(SELECT ALARMDESCRIPTIONTABLE.DESCRIPTION FROM ALARMDESCRIPTIONTABLE) AS BB
ON AA.ID=BB.ID
Both these tables have an id column that relates the id in one table with the description in the other. The idea being i can get a count and description for each alarm. e.g.
AlarmDescription Alarm COUNT

Using the `height` and `line-height` CSS properties, I can almost achieve it, but there's a small offset on the top (`2px` in my example) and I'd like to understand why.
As a workaround, I can set a negative top margin to the image, but I'd like to avoid it if possible (more prone to break across browsers?). I'm also surprised that I need a `-4px` top margin to counteract the `2px` offset.
Any hint?

The webdav is working fine users can access upload, delete and download files fine. However what I want to do is only allow specific users to delete or upload files.
The way I have tried this is using basic apache authentication as below:
<Directory /var/host/myserver/httpdocs/testdav >
Dav On
Allow from all
AuthType Basic
<Limit PUT DELETE MOVE COPY POST>
Require user example
</Limit>
</Directory>
(users are setup in Plesk 10 panel)
The idea here is that all users are denied access to delete or upload except for the user example.
This sort of works in a client such as CyberDuck. Downloading files works and trying to upload/delete files returns a login failed message. I would have expected this to say permission denied or something similar.
However I am trying to use this in ReaddleDocs on the iPad. Again a user can access and download the files by Synchronising the application to the WebDAV. However if they delete a file or create new files in ReaddleDocs and try and synchronise instead of just downloading the deleted files the synchronise fails.
I have created a free account with cloudsafe which offers WebDAV and can allow a user read only access to a folder and I have tested this in the app and works as expected (user deletes local file, when synchronising the file is downloaded again), so I know this is possible.
What I need to know is if this setup is possible in Apache and how?
Any help is much appreciated!

I'm asking for Your help about an issue I'm having with AudioTrack AND AudioRecord. I am trying to record the audio in android using the AudioRecord. I am dumping the data from AudioRecord buffer to byteArrayOutputStream and then byteArrayOutputStream will be stored in the Vector bufList. I've created a separate thread FullMxPlay to play Audio, which will get the data from Vector bufList and dump it to AudioTrack buffer. The code is working fine when the FullMxPlay thread is initialized in stopRecording(), which will play the recorded audio when the recording is stoped. Now I want to initialize the FullMxPlay thread on startRecording() so it will be able to play the audio as it is being recorded.
I've added 100ms delay in thread so that startRecording() being able to dump some data in to Vector before Thread start playing the Audio but it's not working...
Here is my code,

We use the MVVM pattern in conjunction with DelegateCommands. So normally I bind a command to the button like this:
<Button Command="{Binding SetXYZActivatedCommand}" />
I need to execute different commands when the button is pressed and when the button is released again. My idea was the following:
<Button Grid.Row="3" x:Name="TestButtonObj" Content="asdlknm">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" CornerRadius="80" Background="LightBlue">
<ContentPresenter Name="content" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="border" Property="Background" Value="Aqua" />
<Setter TargetName="content" Property="Content" Value="Pressed" />
</Trigger>
<Trigger Property="ClickMode" Value="Press">
<Setter TargetName="TestButtonObj" Property="Command" Value="{Binding SetPttDeactivatedCommand}" />
</Trigger>
<Trigger Property="ClickMode" Value="Release">
<Setter Property="Button.Command" Value="{Binding SetPttActivatedCommand}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
The problem is that TestButtonObj is unknown. Ok I have accepted, that I cannot access the parent object. Without TargetName="TestButtonObj" it compiles, but the command is not executed. Mhhhh...
Ok I tried the following, but it cannot work... CommandBinding is not a dependency property (hopefully you get me out of this labyrinth)
<Button Grid.Row="2" Content="CommandBindings">
<Button.CommandBindings>
<CommandBinding Command="{Binding SetPttActivatedCommand}" />
</Button.CommandBindings>
</Button>
At this point I stuck. I don`t know if the way was completly wrong. I read the whole day docs about commands and binding, but I don't get the clue. I hope, someone can show me the way.
I posted also here today morning:

We have an ASP.Net website, which generates a PDF report. To generate the PDF report we need to make multiple web-service calls (each call returns a part of the data). Most of the calls are to the same endpoint, but the methods and the parameters are different. To improve performance, we have thought of the following 2 approaches:
1. Expose a web service operation that accepts parameters for all the individual calls. Internally, this method calls each of the methods one by one; when completed, it packs all the responses in a collection and sends it back. The ASP.Net web page then receives the list of responses and unpacks them and generates the report.
2. Make parallel calls to the web service methods from the ASP.Net application. When all parallel calls are completed, collect all the responses and generate the PDF.
At first, the 2nd approach looks elegant; the problem is, how do we make the parallel web service calls. Thread.QueueUserWorkItem is not a good option as suggested here:

**Get Entity**
1. Run Action at a controller
2. Fetch data from FactoryClass that operates against the Model(Entity Framework)
3. Get data back to the Action in the controller
4. Use AutoMapper to translate from Model object to ModelView object
5. Return the ModelView object to the strongly typed View
**Update Entity**
1. Run Action with ModelView Entity as input (DefaultDataBinder will be used)
2. Validate ModelView Entity
3. Send the ModelView object direcly to the right factory method.
4. Check if the ModelView object has id and if so fetch the Model object from database
5. Use AutoMapper to translate the incoming ModelView object to a Model object/entity. If its a update, then use the fetched Model object as destination.
6. If it is a update use Refresh Client.Wins else use Add
7. Run SaveChanges and return to the controler.
**Problem 1**
The ModelView classes is special made for the views that the controler actions is connected to (it could contain both edeting objects and lists). It´s common that several actions with diffrent views uses the same ModelView Class, that means that not all objects in the ModelView object will be used in every action/view.
As long as the View uses all the properties of ModelViewObjects that can be updated there is no problem but...
Say that we got a View where some of the properties of the ModelViewObject is not used, this ModelViewObject is sent to the factory(to be updated) where the corsponding ModelObject is fetched(from db/entity framework) and then merged with the ModelViewObject with AutoMapper. The problem here is that properties on the ModelViewObject that is not set(not used in the view) will result in a overwrite of real data in the ModelObject.
To solve this u usually use AutoMapper ForMember Ignor(), but this will be a problem when a complete ModelViewObject(all properties set) will update db.
How do you handle this? Do you have diffrent Update methods in the factorys where diffrent AutoMapper setting?
It would be nice If I could only have a method like this : UpdateMyEnityt(MyEntity entity) and this methid will update och add MyEntity object.
**Problem 2**
Where should I place the AutoMapper mappings? So far I have placed **Updates** in the factory and **Get** in the controller. I have thought of placeing the mappings in the ModelViewObject for example ModelViewObject.ToDataModel but if I do not need a complete translate(som properties is to be ignored) then I will have to do this AutoMapper else where.
How do you handle this?
**Problem 3**
Say that you have an working update method in our factory class where you use AutoMapper with som ignors to translate a ModelViewObject to a ModelView(entity framework object). Say now that we updates the database table with a new field/propertie, if we run a view that handles the ModelViewObject corsponding to this tabel but do not handle the new propertie this will mean that the propertie will always be set to null/string.empty/0. When running the regular update method in the factory there will not be a ignor on this propertie and this means that the zero value will overrite the real value.
Its a big risk that these kind of updates will be done and its a big risk that I will not remember to handle this in old code.
How do I handle this?
**Problem 4**
AutoMapper have a validation method where you can check if the mappings will be possible, right now I am having these validations where the mapping is done, should I maby put this in some other method where the validation will be executed as fast as the application starts? Else problems in the mappings will show first when using the function.

===
I am trying to use WebLogic 2-way SSL configuration on Weblogic 9.2. I have created the Server Certificate & key files (ServerCert.pem, ServerKey.pem) and Client Certificate & key files (ClientCert.pem, ClientKey.pem) by following instructions given on link:
http://weblogictips.wordpress.com/2010/05/20/two-way-ssl-on-weblogic-server/
I am using CertGen to create the Certificate files and using DemoTrust as the Trust Store. In short, I created client Certificate and Key files using Certgen tool command:
> java utils.CertGen -certfile ClientCert -keyfile ClientKey
> -keyfilepass keypass
and
> pkcs12 -export -in C:\ServerCert\ClientCert.pem -inkey
> C:\ServerCert\ClientKey.pem -out C:\ServerCert\client-pkcs-12-cert
and then added the certificate to the Mozilla Browser.
The command I am using is:
> java -Dweblogic.home="~/bea/weblogic92/server"
> -Dweblogic.security.TrustKeyStore=DemoTrust -Dssl.debug=true -Dweblogic.StdoutDebugEnabled=true -jar mytestplugin.jar t3s://x.x.x.x:7002 weblogic weblogic ClientKey.pem ClientCert.pem
> keypass
And my code looks like:
weblogic.jndi.Environment environment = new weblogic.jndi.Environment.Environment();
environment.setProviderUrl(t3s://x.x.x.x:7002);
environment.setSecurityPrincipal(weblogic);
environment.setSecurityCredentials(weblogic);
InputStream key = new FileInputStream(new File(ClientKey.pem));
InputStream cert = new FileInputStream(new File(ClientCert.pem));
key = new PEMInputStream(key);
cert = new PEMInputStream(cert);
environment.setSSLClientCertificate(new InputStream[] { key, cert});
environment.setInitialContextFactory(Environment.DEFAULT_INITIAL_CONTEXT_FACTORY);
environment.setSSLClientKeyPassword("keypass");
Context context = environment.getInitialContext(); //This line throws exception
The last line throws exception:
> FINE: Failure loading trusted CA list
> java.security.cert.CertificateException: Could not get public key for:
> C=US, ST=MyState, L=MyTown, O=MyOrganization, OU=FOR TESTING ONLY,
> CN=CACERT at

and
> FINE: Problem accessing private key

I can't decide when to make a Class and when not to. I've heard that for simple functionalities only a function would suffice. I don't want to make up Classes for every random things that I implement on the site.
It's said "Classes are representation of data" - does that mean we only need to make classes for the individual tables int he database?

**2.** Is it possible to have an iAd displayed only sometimes? For example, only on the main menu/pause screen? Is it feasible to do so?

I create stress test to my swing app. swing app call remote EJB method which returns List of entities. I put remote method invocation in for loop and set max iteration to 5000 calls to server, after that I run 2 clients but after some number of calls, server throws exception

I'm wrapping that in a little html and putting it into a web view like this:
NSString *cssPath = [[NSBundle mainBundle] pathForResource:@"style" ofType:@"css"];
NSString *cssLink = [NSString stringWithFormat:@"<link href='file://%@/' type='text/css' rel='stylesheet'/>", cssPath];
NSString *html = [[NSString stringWithFormat:@"<html><head><title></title><meta charset='UTF-8' />%@</head><body>%@</body></html>", cssLink, htmlContent] retain];
[myWebView loadHTMLString:html baseURL:currentURL];
Is there any way to fix the above code so that the link to the local stylesheet works?
I could load the stylesheet without problem if I change the base url to the local application resources file, but this breaks the image links within the html loaded from the server.
I could also include the contents of the stylesheet directly into the html, but would prefer not to do that for a number of reasons.

These are all in an array of XML objects, I need to sort through the array and set up (obviously) a FAQ section for this site. The problem I am having is that since this is not 1 xml document but a collection of xml documents, I am having a hard time sorting/separating by Main category > Sub category.
Here is where I am so far with the getting of the main categories:
Protected Sub getFaqData(ByVal DocArray() As CMSWS.CMSDocumentRecord)
Dim mainFaqCategoryItem As String = ""
Dim mainCategoryList As New List(Of String)
For Each Doc As CMSWS.CMSDocumentRecord In DocArray
xml.LoadXml(Doc.Xml)
Try
mainFaqCategoryItem = CType(xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText, String)
If Not mainCategoryList.Contains(mainFaqCategoryItem) Then
mainCategoryList.Add(mainFaqCategoryItem)
End If
Catch ex As Exception
Response.Write("ERROR getting the main category")
End Try
Next
For Each item In mainCategoryList
outputsubs(item, DocArray)
Next
End Sub
Here is the start of getting the sub categories and where I am stuck:
Protected Sub outputsubs(ByVal item As String, ByVal DocArray() As CMSWS.CMSDocumentRecord)
Dim subFaqCategoryItem As String = ""
Dim subcategoryList As New List(Of String)
'Add the main Category to the HTML output:
lblFaq.Text = lblFaq.Text & "<h1>" & item & "</h1>"
For Each Doc As CMSWS.CMSDocumentRecord In DocArray
xml.LoadXml(Doc.Xml)
Try
'If xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText = item Then
subFaqCategoryItem = CType(xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText, String)
If Not subcategoryList.Contains(subFaqCategoryItem) Then
subcategoryList.Add(subFaqCategoryItem)
End If
'End If
Catch ex As Exception
Response.Write("ERROR getting the main category")
End Try
Next
For Each subItem In subcategoryList
lblFaq.Text += "<h2><a name=""subCategory"" style=""text-decoration:none;""><span class=""FAQPlusMinus""> + </span>" & subItem & "</a></h2>"
Next
End Sub
My thinking is that I will need to set up for-each loops nested to about 3 levels to get this to work, but I can't get my brain around it. Especially since it isn't a single XML document.
Which works to display the main categories

Here is the start of getting the sub categories and where I am stuck:
Protected Sub outputsubs(ByVal item As String, ByVal DocArray() As CMSWS.CMSDocumentRecord)
Dim subFaqCategoryItem As String = ""
Dim subcategoryList As New List(Of String)
'Add the main Category to the HTML output:
lblFaq.Text = lblFaq.Text & "<h1>" & item & "</h1>"
For Each Doc As CMSWS.CMSDocumentRecord In DocArray
xml.LoadXml(Doc.Xml)
Try
'If xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText = item Then
subFaqCategoryItem = CType(xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText, String)
If Not subcategoryList.Contains(subFaqCategoryItem) Then
subcategoryList.Add(subFaqCategoryItem)
End If
'End If
Catch ex As Exception
Response.Write("ERROR getting the main category")
End Try
Next
For Each subItem In subcategoryList
lblFaq.Text += "<h2><a name=""subCategory"" style=""text-decoration:none;""><span class=""FAQPlusMinus""> + </span>" & subItem & "</a></h2>"
Next
End Sub
My thinking is that I will need to set up for-each loops nested to about 3 levels to get this to work, but I can't get my brain around it. Especially since it isn't a single XML document.
Which works to display the main categories

In another post I asked about how to structure a Django project and applications using buildout. In the details of doing this arose another issue, simply installing 3rd party Django applications using either easy_install or setup.py. My question is, where should you install a Django application? If looking at Django documentation, one would think to put a Django application inside the project folder. But if your Django application is an egg (a mystifying term in my opinion) and you use easy_install without option '-b' (build-directory) the application will be installed into your current python site-packages directory. Using option '-b' will put a copy of the application in your directory, but still will install it in your current site-packages directory. Then there are other options like --install-dir and prefix. Also how should installation happen when using setup.py which have similar options as buid-directory, install-dir, and prefix?
Is there a 'good practice' standard for installing 3rd party Django applications into a Django project?
Thank a lot,

We are developing a web application for banks. This is a website for clients of the bank; it allows clients to log in and view information on their personal banking accounts, stock portfolios, etc.
Can this web app use SQL Server 2008 Web Edition?
Here is information on this edition of SQL Server:

It is said on this page that Web Edition can be used only on "**public and Internet accessible** ... Web applications".

I wrote them in batch first, but there's a little logic in them, so I thought it might be best to write them in a more readable language. The project is free open-source, so I want it to build in Visual C# Express 2010 and SharpDevelop as well as VS2010, and avoid third-party software.
I found [MSBuild Inline Tasks](http://msdn.microsoft.com/en-us/library/dd722601%28VS.100%29.aspx), which might serve this purpose. I figure it would be more intuitive to other developers if the build tasks were a file in the project (instead of in the project file), and apparently there is a way to do this, but I haven't found any good resources on it.
