I have read the tutorials and anything else I could find on developing KLD's which isn't much of a problem, but can anyone tell me, for example, how I could obtain the src and dest address of a packet that is being processed by the system?
I was also thinking of perhaps using IPF to redirect packets (i.e. all FTP data) to a program for analysis instead of hooking directly into the stack as mentioned above. Is this possible? I don't want to have to use libpcap as I want to be able to manipulate real packets in real time and not just copies.
Any information would be greatly appreciated.

This is particularly true when using agile methodologies, which emphasize minimalistic documentation.
The issue with development-oriented documentation is that it tends to be less usable as a reference, especially after a few releases. It's a pain to sifting through a pile of story cards (or story pages on a wiki, as our team uses) trying to work out which stories are current, and which have been modified (directly or indirectly) by more recent stories. A full waterfall-style requirements specification, technical-design document, etc. may be fine if development is always done in a big bang, but as bugs are fixed, minor features added, etc. it may be difficult to maintain.
I'm a fan of minimalistic documentation, as the less documentation there is, the easier it is to find things (assuming what you're looking for is documented, of course), and the easier it is to maintain.
I am thinking of extending our wiki-based story pages to contain some meta-data, i.e. references to other stories which are related, affected, obsoleted, etc., similar to [IETF RFPs][1].
I'm interested in hearing about other peoples' experiences with lightweight approaches to software documentation that works for maintenance and support, not just delivering a project and tossing it over the wall.

var xml:XML = <root><node>value1</node><node>value2</node><node>value3</node></root>
At runtime, I want to create a TextInput control for each node under root, and have the values bound to the values in the XML. As far as I can tell I can't use BindingUtils to bind to e4x nodes at runtime (please tell me if I'm wrong here!), so I'm trying to do this by hand:
for each (var node:XML in xml.node)
{
var textInput:TextInput = new TextInput();
var handler:Function = function(event:Event):void
{
node.setChildren(event.target.text);
};
textInput.text = node.text();
textInput.addEventListener(Event.CHANGE, handler);
this.addChild(pileHeightEditor);
}
My problem is that when the user edits one of the TextInputs, the node getting assigned to is always the last one encountered in the for loop. I am used to this pattern from C#, where each time an anonymous function is created, a "snapshot" of the values of the used values is taken, so "node" would be different in each handler function.
How do I "take a snapshot" of the current value of node to use in the handler? Or should I be using a different pattern in Flex? | javascript | flex | e4x | null | null | null | open | Editing XML in Flex using e4x

I would like to
- take in data from an outside source (or hardcode it in for testing purposes)
- draw the graph
- Hover over a node/bar and have a tooltip appear displaying the number/relevant data.
So my question is, it is possible to apply tooltips to individual images/lines/anything on a canvas? (I know that the canvas itself can have it's own tooltip)
One solution that I'm sure would work would be to just make each node a separate canvas with it's own tooltip and image but that sounds a bit excessive.
And ideally I would like to use jquery.ui.tooltip, but really I just want to know if anything will work.
var imageObj = new Image();
$(imageObj).attr("title","kitten");
$(imageObj).tooltip();
imageObj.onload = function(){
context.drawImage(imageObj, destX, destY, destWidth, destHeight);
};
imageObj.src = "BW-kitten.jpg";
I got the outline from [here](http://www.html5canvastutorials.com/tutorials/html5-canvas-image-size/) and added what I thought could possibly work.

I have a form with a BindingNavigator on it. There's a binding source declared and all hooked up. There's 2 text boxes on the form and a Public withevents instance of my class inherited from a BindingList(of T) - ThingCollection.
If I create a new Thing using the Navigator, the "AddNewCore" method of ThingCollection gets called by the Navigator and I happily create a new instance of Thing amd add it to the collection and write the data to a database.
If I edit an item on the form, I can pick up the change in the Property of the Thing and write the changes to the database.
Likewise on startup I can happily read from the database, create instances of Thing and add them to the ThingCollection.
My problem comes on clicking the Delete button on the Navigator. How do I hook that back to the ThingCollection on the instance of Thing so that I can delete it?
I appreciate I could use BindingNavigatorDeleteItem_Click on the form, then go through and try and find out what's missing, but that seems a really messay way of doing things compared to the Create, Read and Update. I could also disable the delete button and add my own, but that's not much better.

For encoding, I am using the [Windows Media Video 9 Screen][2] codec because it is very efficient for screen captures and because it is available to practically everybody without the need to install anything, as the codec is included with Windows Media Player 9 runtime (included in Windows XP SP1).
I am making BITMAP screen shots using the GDI functions and feed those BITMAPs to the encoder. As you can guess, taking screen shots with GDI is slow, and I don't get the screen cursor, which I have to add manually to the BITMAPs. The BITMAPs I get initially are DDBs, and I need to convert those to DIBs for the encoder to understand (RGB input), and this takes more time.
Firing a profiler shows that about 50% of the time is spent in WMVCORE.DLL, the encoder. This is to be expected, of course as the encoding is CPU intensive.
The thing is, there is something called [Windows Media Encoder][3] that comes with a SDK, and can do screen capture using the desired codec in a simpler, and more CPU friendly way.
The WME is based on WMF. It's a higher lever library and also has .NET bindings. I can't use it in my project because this brings unwanted dependencies that I have to avoid.
I am asking about the method WME uses for feeding sample data to the WMV encoder. The encoding takes place with WME exactly like it takes place with my application that uses WMF. WME is more efficient than my application because it has a much more efficient way of feeding video data to the encoder. It doesn't rely on slow GDI functions and DDB->DIB conversions.
How is it done?
Thanks in advance,

I am using [Windows Media Format SDK][1] to capture the desktop in real time and save it in a WMV file (actually this is an oversimplification of my project, but this is the relevant part). For encoding, I am using the [Windows Media Video 9 Screen][2] codec because it is very efficient for screen captures and because it is available to practically everybody without the need to install anything, as the codec is included with Windows Media Player 9 runtime (included in Windows XP SP1).
I am making BITMAP screen shots using the GDI functions and feed those BITMAPs to the encoder. As you can guess, taking screen shots with GDI is slow, and I don't get the screen cursor, which I have to add manually to the BITMAPs. The BITMAPs I get initially are DDBs, and I need to convert those to DIBs for the encoder to understand (RGB input), and this takes more time.
Firing a profiler shows that about 50% of the time is spent in WMVCORE.DLL, the encoder. This is to be expected, of course as the encoding is CPU intensive.
The thing is, there is something called [Windows Media Encoder][3] that comes with a SDK, and can do screen capture using the desired codec in a simpler, and more CPU friendly way.
The WME is based on WMF. It's a higher lever library and also has .NET bindings. I can't use it in my project because this brings unwanted dependencies that I have to avoid.
I am asking about the method WME uses for feeding sample data to the WMV encoder. The encoding takes place with WME exactly like it takes place with my application that uses WMF. WME is more efficient than my application because it has a much more efficient way of feeding video data to the encoder. It doesn't rely on slow GDI functions and DDB->DIB conversions.
How is it done?
Thanks in advance,
A.

I later saw Joel's invitation to this site, and I thought I'd paste it here to see if anyone has any insight into the situation.
I wrote, and now support, an application that consists of a Visual Basic thick client speaking DCOM to middle tier COM+ components written in C++ using ATL. It runs in all eight of our offices. Each office hosts a back-end server that contains the COM+ application (consisting of 18 separate components) and the SQLServer. The SQLServer is typically on the same back-end server, but need not be.
We recently migrated the back-end server in our largest office -- New York -- from a MSC cluster to a new virtual machine hosted on VMWare's ESX technology. Since the location of the COM+ application had moved from the old server to a new one with a different name, I had to redirect all the clients so that they activated the COM+ application on the new server. The procedure was old hat as I had done essentially the same thing for several of my smaller offices that had gone through similar infrastructure upgrades.
All seemed routine and on Monday morning the entire office -- about 1,000 Windows XP workstations -- were running without incident on the new server. But then the call came from my mobile group -- there was an attorney working from home with a VPN connection that was getting a strange error after being redirected to the new server:
<pre>
Error on FillTreeView2 - The stub received bad data.
</pre>
Huh? I had never seen this error message before. Was it the new server? But all the workstations in the office were working fine. I told the mobile group to switch the attorney back to the old sever (which was still up), and the error disappeared. So what was the difference? Turns out this attorney was running Vista at home.
We don't run Vista in any of our offices, but we do have some attorneys that run Vista at home (certainly some in my New York office). I do as well and I've never seen this problem. To confirm that there was an issue, I fired up my Vista laptop, pointed it to the new server, and got the same error. I pointed it back to the old server, and it worked fine. Clearly there was some problem with Vista and the components on the new server -- a problem that did not seem to affect XP clients. What could it be?
Next stop -- the application error log on my laptop. This yielded more information on the error:
<pre>
Source: Microsoft-Windows-RPC-Events
Date: 9/2/2008 11:56:07 AM
Event ID: 10
Level: Error
Computer: DevLaptop
Description: Application has failed to complete a COM call because an incorrect
interface ID was passed as a parameter.
The expected Interface ID was 00000555-0000-0010-8000-00aa006d2ea4,
The Interface ID returned was 00000556-0000-0010-8000-00aa006d2ea4.
User Action - Contact the application vendor for updated version of the application.
</pre>
The interface ids provided the clue I needed to unravel the mystery. The "expected" interface id identifies MDAC's Recordset interface -- specifically version 2.1 of that interface. The "returned" interface corresponds to a later version of Recordset (version 2.5 which differs from version 2.1 by the inclusion of one additional entry at the end of the vtable -- method Save).
Indeed my component's interfaces expose many methods that pass Recordset as an output parameter. So were they suddenly returning a later version of Recordset -- with a different interface id? It certainly appeared to be the case. And then I thought, why should it matter. The vtable looks the same to clients of the older interface. Indeed, I suspect that if we were talking about in-process COM, and not DCOM, this apparently innocuous impedance mismatch would have been silently ignored and would have caused no issues.
Of course, when process and machine boundaries come into play, there is a proxy and a stub between the client and the server. In this case, I was using type library marshaling with the free threaded marshaller. So there were two mysteries to solve:
Why was I returning a different interface in the output parameters from methods on my new server?
Why did this affect only Vista clients?
As my server software was hosted on servers at each of my eight offices, I decided to try pointing my Vista client at all of them in sequence to see which had problems with Vista and which didn't. Illuminating test. Some of the older servers still worked with Vista but the newer ones did not. Although some of the older servers were still running Windows 2000 while the newer ones were at 2003, that did not seem to be the issue.
After comparing the dates of the component DLLs it appeared that whenever the client pointed to servers with component DLLs dated before 2003 Vista was fine. But those that had DLLs with dates after 2003 were problematic. Believe it or nor, there were no (or at least no significant) changes to the code on the server components in many years. Apparently the differing dates were simply due to recompiles of my components on my development machine(s). And it appeared that one of those recompiles happened in 2003.
The light bulb went on. When passing Recordsets back from server to client, my ATL C++ components refer to the interface as _Recordset. This symbol comes from the type library embedded within msado15.dll. This is the line I had in the C++ code:
<pre>
#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename ( "EOF", "adoEOF" )
</pre>
Don't be deceived by the 15 in msdad15.dll. Apparently this DLL has not changed name in the long series of MDAC versions.
When I compiled the application back in the day, the version of MDAC was 2.1. So _Recordset compiled with the 2.1 interface id and that is the interface returned by the servers running those components.
All the client's use the COM+ application proxy that was generated (I believe) back in 1999. The type library that defines my interfaces includes the line:
<pre>
importlib("msado21.tlb");
</pre>
which explains why they expect version 2.1 of Recordset in my method's output parameters. Clearly the problem was with my 2003 recompile and the fact that at that time the _Recordset symbol no longer corresponded to version 2.1. Indeed _Recordset corresponded to the 2.5 version with its distinct interface id. The solution for me was to change all references from _Recordset to Recordset21 in my C++ code. I rebuilt the components and deployed them to the new server. Voila -- the clients seemed happy again.
In conclusion, there are two nagging questions that remain for me.
Why does the proxy/stub infrastructure seem to behave differently with Vista clients. It appears that Vista is making stricter checks of the interface ids coming back from method parameters than is XP.
How should I have coded this differently back in 1999 so that this would not have happened? Interfaces are supposed to be immutable and when I recompiled under a newer version of MDAC, I inadvertently changed my interface because the methods now returned a different Recordset interface as an output parameter. As far as I know, the type library back then did not have a version-specific symbol -- that is, later versions of the MDAC type libraries define Recordset21, but that symbol was not available back in the 2.1 type library.

The Interface ID returned was 00000556-0000-0010-8000-00aa006d2ea4.
User Action - Contact the application vendor for updated version of the application.
</pre>
The interface ids provided the clue I needed to unravel the mystery. The "expected" interface id identifies MDAC's Recordset interface -- specifically version 2.1 of that interface. The "returned" interface corresponds to a later version of Recordset (version 2.5 which differs from version 2.1 by the inclusion of one additional entry at the end of the vtable -- method Save).
Indeed my component's interfaces expose many methods that pass Recordset as an output parameter. So were they suddenly returning a later version of Recordset -- with a different interface id? It certainly appeared to be the case. And then I thought, why should it matter. The vtable looks the same to clients of the older interface. Indeed, I suspect that if we were talking about in-process COM, and not DCOM, this apparently innocuous impedance mismatch would have been silently ignored and would have caused no issues.
Of course, when process and machine boundaries come into play, there is a proxy and a stub between the client and the server. In this case, I was using type library marshaling with the free threaded marshaller. So there were two mysteries to solve:
Why was I returning a different interface in the output parameters from methods on my new server?
Why did this affect only Vista clients?
As my server software was hosted on servers at each of my eight offices, I decided to try pointing my Vista client at all of them in sequence to see which had problems with Vista and which didn't. Illuminating test. Some of the older servers still worked with Vista but the newer ones did not. Although some of the older servers were still running Windows 2000 while the newer ones were at 2003, that did not seem to be the issue.
After comparing the dates of the component DLLs it appeared that whenever the client pointed to servers with component DLLs dated before 2003 Vista was fine. But those that had DLLs with dates after 2003 were problematic. Believe it or nor, there were no (or at least no significant) changes to the code on the server components in many years. Apparently the differing dates were simply due to recompiles of my components on my development machine(s). And it appeared that one of those recompiles happened in 2003.
The light bulb went on. When passing Recordsets back from server to client, my ATL C++ components refer to the interface as _Recordset. This symbol comes from the type library embedded within msado15.dll. This is the line I had in the C++ code:
<pre>
#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename ( "EOF", "adoEOF" )
</pre>
Don't be deceived by the 15 in msdad15.dll. Apparently this DLL has not changed name in the long series of MDAC versions.
When I compiled the application back in the day, the version of MDAC was 2.1. So _Recordset compiled with the 2.1 interface id and that is the interface returned by the servers running those components.
All the client's use the COM+ application proxy that was generated (I believe) back in 1999. The type library that defines my interfaces includes the line:
<pre>
importlib("msado21.tlb");
</pre>
which explains why they expect version 2.1 of Recordset in my method's output parameters. Clearly the problem was with my 2003 recompile and the fact that at that time the _Recordset symbol no longer corresponded to version 2.1. Indeed _Recordset corresponded to the 2.5 version with its distinct interface id. The solution for me was to change all references from _Recordset to Recordset21 in my C++ code. I rebuilt the components and deployed them to the new server. Voila -- the clients seemed happy again.
In conclusion, there are two nagging questions that remain for me.
Why does the proxy/stub infrastructure seem to behave differently with Vista clients. It appears that Vista is making stricter checks of the interface ids coming back from method parameters than is XP.
How should I have coded this differently back in 1999 so that this would not have happened? Interfaces are supposed to be immutable and when I recompiled under a newer version of MDAC, I inadvertently changed my interface because the methods now returned a different Recordset interface as an output parameter. As far as I know, the type library back then did not have a version-specific symbol -- that is, later versions of the MDAC type libraries define Recordset21, but that symbol was not available back in the 2.1 type library.

I am fairly impressed, however as I continue to piece together a game engine, I have a (probably) basic question.
How much should you rely on C#'s Delegates and Events to drive the game? As an application programmer, I use delegates and events heavily, but I don't know if there is a significant overhead to doing so.
In my game engine, I have designed a "chase cam" of sorts, that can be attached to an object and then recalculates its position relative to the object. When the object moves, there are two ways to update the chase cam.
* Have an "UpdateCameras()" method in the main game loop.
* Use an event handler, and have the chase cam subscribe to object.OnMoved.
I'm using the latter, because it allows me to chain events together and nicely automate large parts of the engine.
However, if event handlers firing every nanosecond turn out to be a major slowdown, I'll remove it and go with the loop approach.
Ideas? | c# | xna | camera | null | null | null | open | Game Programming and Event Handlers

I mainly use python to open/edit/read these files. However I may need to use other programs as well.
I used to use XML/XPATH. However, the xpath libraries are frail and don't work on most systems withtout a significant amount of frustration. I am tired trying to figure out xpath this I port my scripts to different platform.

BTW, `sudo apt-get install python-xml` does not fix this problem.
The bottom line is that I am fed up with xml/xpath. I want a solution that will work in all cases, on all platforms, without question!
What can I use? Advice?

When I select a different object (in a combobox above), I need to update the grid. Unfortunately different objects have completely different data, even different columns, so I need to clear all the existing data and columns, create new columns and add all the rows. When this is done, the whole control flickers horribly and it takes ages. Is there a generic way to get the control in an update state so it doesn't repaint itself, and then repaint it after I finish all the updates?
It is certainly possible with TreeViews:
myTreeView.BeginUpdate();
try

//do the updates
}
finally
{
myTreeView.EndUpdate();
}
Is there a generic way to do this with other controls, DataGridView in particular?

dim a as New Foo()
dim b as New Foo()
and a would get a unique id and b would get a unique ID. The ids only have to be unique over run time so i would just like to use an integer. I have found a way to do this BUT (and heres the caveat) I do NOT want to be able to change the ID from anywhere. My current idea for a way to implement this is the following:
Public Class test
Private Shared ReadOnly _nextId As Integer
Private ReadOnly _id As Integer
Public Sub New()
_nextId = _nextId + 1
_id = _nextId
End Sub
End Class
However this will not compile because it throws an error on
_nextId = _nextId + 1
I don't see why this would be an error (because _Id is also readonly you're supposed to be able to change a read only variable in the constructor.) I think this has something to do with it being shared also. Any solution (hopefully not kludgy hehe) or an explanation of why this won't work will be accepted. The important part is i want both of the variables (or if there is a way to only have one that would even be better but i don't think that is possible) to be immutable after the object is initialized.
