Self update application while running in memory
|
<p>I have a console app that is triggered by a scheduled task. I would like to run this console app permanently in a new thread and anytime a newer version of the console app is placed, it should run the main code. (maybe once the main code is done executing, it should run a monitor thread on the console exe. When the exe is changed, a shell execute could be called to the console app again and the original thread aborted?).</p>

jquery on input blur show / hide class
|
<p>I am currently building an html form and using jquery to validate.</p>
<p>Each input field is set up like this:</p>
<pre><code><div class="controls">
<input type="text" class="input-xlarge" name="name" id="name">
<div class="info">&nbsp;</div>
<div class="valid" style="display:none;">&nbsp;</div>
</div>
</code></pre>
<p>Here is my jquery so far:</p>
<pre><code>$('.controls input').blur(function() {
if( !$(this).val() ) {
$(this).css('border-color','red');
$(this).find('.info').css('display','none');
$(this).find('.error').css('display','inline-block');
</code></pre>
<p>The idea is when the user view the form, the info div shows. If they proceed with the form tabbing through the inputs without enetering any information, the error class will show and remove the info class.</p>
<p>Any ideas on where im going wrong?</p>
<p>Cheers, Dan</p>

How to design a JavaScript class to support callbacks in a clean way?
|
<p>I've tried to design some classes to support a callback functionality. Classes MyClass1 and MyClass2 didn't work. Class3 worked, but the design is really horrible. It uses a external class reference to call the method. I'd like to implement a design similar to MyClass1, which is a lot clearer and isn't coupled to an external variable. This callback mechanism would really be great to ajax calls too.
$j is just an alias to jQuery.</p>
<pre><code>function MyClass1() {
$j("#myDiv1").click(this.func);
this.func = function() {
alert("Inside method.");
}
}
var _class2;
function MyClass2() {
_class2 = this;
$j("#myDiv2").click( _class2.func );
this.func = function() {
alert("Inside method.");
}
}
function MyClass3() {
$j("#myDiv3").click( function() { cls3.func(); } );
this.func = function() {
alert("Inside method.");
}
}
var cls1 = new MyClass1();
var cls2 = new MyClass2();
var cls3 = new MyClass3();

PHP Remove URL from string

<p>If I have a string that contains a url (for examples sake, we'll call it $url) such as;</p>
<pre><code>$url = "Here is a funny site http://www.tunyurl.com/34934";
</code></pre>
<p>How do i remove the URL from the string?
Difficulty is, urls might also show up without the http://, such as ;</p>
<pre><code>$url = "Here is another funny site www.tinyurl.com/55555";
</code></pre>
<p>There is no HTML present. How would i start a search if http or www exists, then remove the text/numbers/symbols until the first space?</p>

How can I create News Android application without having my own server?
|
<p>I have tried to create a news app that display news from some website.<br>
Some friends helped me to write some php so that I can call the php using http request and get the JSON from the response.<br>
Then, I can parse the JSON and display the news correctly.<br>
However, the server is not mine.<br>
Actually, I don't want to have server communication using php.<br>
I want to do it just on client side.<br>
1) I know how to parse the html and get the result using python in local machine, is there any way to implement my python code in Android, and after running the python code, it will connect to the news website and display it correctly.<br>
2) If not, what can I do because I do not want to host a server. </p>

issue with using std::copy
|
<p>I am getting warning when using the std copy function.</p>
<p>I have a byte array that I declare. </p>
<pre><code>byte *tstArray = new tstArray[length];
</code></pre>
<p>Then I have a couple other byte arrays that are declared and initialized with some hex values that i would like to use depending on some initial user input. </p>
<p>I have a series of if statements that I use to basically parse out the original input, and based on some string, I choose which byte array to use and in doing so copy the results to the original tstArray.</p>
<p>For example:</p>
<pre><code>if(substr1 == "15")
{
std::cout<<"Using byte array rated 15"<<std::endl;
std::copy(ratedArray15,ratedArray15+length,tstArray);
}
</code></pre>
<p>The warning i get is
warning C4996: 'std::copy': Function call with parameters
that may be unsafe
- this call relies on the caller to check that the passed
values are correct.</p>
<p>A possible solution is to to disable this warning is by useing -D_SCL_SECURE_NO_WARNINGS, I think. Well, that is what I am researching.</p>
<p>But, I am not sure if this means that my code is really unsafe and I actually needed to do some checking?</p>

Method to recursively delete any directory that has no files, my solution seems to work but trying to find ways it can break

<p>This method will delete any files and empty directories provided in the fileList. It seems to be working. I use recursion to delete the empty directories and i'm worried about cases that will create an infinite loop. Any thoughts or things to consider with this approach?</p>

boolean result = true;
List<File> returnList = new LinkedList<File>();
for (File file : fileList) {
result = file.delete();
if(result == false && file.isDirectory()) {

How can I store reference to a variable within an array?

<p>I'm trying to create an array that maps strings to variables. It seems that the array stores the current value of the variable instead of storing a reference to the variable.</p>

var array = [];
array["reference"] = name;
name = "bar";
// Still returns "foo" when I'd like it to return "bar."
array["reference"];

jQuery softscroll.js works in all browsers in the demo, but doesnt work in safari on my website?
|
<p>Basically what i say in the title is what goes.. Ill show you some of the code and give an explanation.</p>
<p>Here's the website page: <a href="http://eosa.co.cc/themes/osoa/portfolio.html" rel="nofollow">http://eosa.co.cc/themes/osoa/portfolio.html</a></p>
<p><strong>As this doesnt let me post more than 1 link due to spam ive put 2 others links in big orange letters at the top so you can see the demo page and the JS for the softscroll</strong></p>
<p>the arrows on the right side are what im refering too, they scroll in all browsers fine apart from safari? No idea why it wont work seeing as the demo works fine in safari.</p>
<p>and heres some html for the links used:</p>
<pre><code><div class="fullwidthbox">
<div class="portfoliogrouptitle">
<h1>Logo Design</h1>
</div>
<a href="#webdesign" class="scroll portfolionav-up"></a>
<a href="#prints" class="scroll portfolionav-down"></a>
</div>
</code></pre>
<p>And heres what they would link onto...</p>
<pre><code><hr class="contenthr" style="margin-bottom:30px" id="prints"/>
</code></pre>
<p>Im not sure what else to say?? but visit the site and the arrows on the right are anchor links to different sections, you'll understand better once you take a look. Also apologies for the speed of the site, its free hosting.</p>

Web frontend for a Python application
|
<p>I created a nice RSS application in Python. It took a while and most of the code just does heavy work, like formatting XML, downloading feeds, etc. To the application itself requires very little user interaction, just a initial list of RSS feeds and some parameters. </p>
<p>What would be really nice, is if I was able to have a web front-end which allowed me to have the user edit their feeds and parameters, then they could click a create button and it runs. </p>
<p>I don't really want to have to rewrite the thing in a web framework. Is there anything that will allow me to build a nice front-end allowing it to interact with the normal Python underneath?</p>

Android TrafficStats delivering wrong numbers
|
<p>I want to measure the data transferred and received for my HTTP request over the mobile network. I found the TrafficStats API in Android 2.2, but the numbers I get from this seem to be too low. I am measuring on a real device (HTC Desire), over 3G network.
Immediately before the request a compute the tx/rx data since boot time, then do a GET request, then calculate the rx/tx numbers again:</p>
<pre><code>long bytesStart = TrafficStats.getTotalTxBytes() + TrafficStats.getTotalRxBytes();
// execute request (Apache HTTP client)
client.execute(get);
long totalBytesNow = TrafficStats.getTotalTxBytes() + TrafficStats.getTotalRxBytes();
long bytesDiff = totalBytesNow - bytesStart;
</code></pre>
<p>For bytesDiff I get numbers around 1.5KB, where it should have been 3.5KB. The totalBytes number is around 5MB, which seems to be a reasonable amount of data for 10 hours that the device is running.</p>
<p>I read <a href="http://stackoverflow.com/questions/4029186/can-someone-explain-how-trafficstats-works-its-magic-in-the-android-os">here on stackoverflow</a> that the numbers come from a file, can it be that the data is not flushed to the file immediately? Or why are my numbers always too low (I checked the data size on the server and it is really larger)?
Is it a problem of my HTC Desire device (Android 2.2 by HTC), does the TrafficStats API work for anyone?</p>
<p>Thanks,
Martin</p>

C++ template specialization question
|
<p>I'm trying to implement a generic toString() function that would work on all types. All our internal classes derive from Abstract which includes a signature for toString(). In other words, all our internal classes have in some form, a toString method. </p>
<p>The problem is, the primitive types (int, char, double..) don't have a native toString function. But we do have a utility function that calls the lexical_cast to give back the string value of the primitive. We don't want a whole bunch of if statements depending So I'm trying to create a templated utility class that would do the job.</p>
<p>My first hack at this is the below:</p>
<pre><code> template<class T>
class ObjectToString {
public:
string objectToString(T value) {
iil::stringUtils::StringSp ret(stringUtils::valueToString<T>(value));
return ret;
}
};
template<>
class ObjectToString <Abstract<T>*> {
public:
iil::stringUtils::StringSp objectToString(Abstract<T>* value) {
return iil::stringUtils::StringSp(new std::string("AAAA"));
}
};
</code></pre>
<p>The problem now is, since Abstract is a templated class, it needs the template value T. I have no idea how to set that. Could anyone advise?</p>

<p>I have a service that basically manages a MediaPlayer instance for playing podcasts. Once an activity binds to the service it can do things like play, pause, stop, etc. I used a service because I want the podcast to continue playing even after the activity is destroyed.</p>
<p>I'd like the service to be able to send messages back to the activity in case of an error or for normal status updates. Is it possible for the service to get a reference to the activity that's trying to bind to it? Doesn't look like the intent makes this available.</p>

<p>This is what I'm doing at the moment at ListView:</p>

<p>this can deduce that C++ doesn't support variable length parameters...</p>

Block a user from a website in ASP.NET
|
<p>Beside IP blocking and probably using a cookie (if the user changes the IP but doesn't remove the cookie, the new IP is added to the banned list, so the IP has to be changed and the cookie has to be removed together to access the site), is there any tricks one can use to block an annoying user from a website, I know that nothing will work with a savvy user but I'm trying to make it harder for the less savvy ones, any suggestions?</p>
<p>Edit: I already have registration in my website, the point is that this is useless to stop determined users (they can simply create other accounts).</p>
<p>@rifferte,
Actually I'm already building a moderation section where moderators can remove posts and suspend members, also members can report abuse and spam, I'm not trying to make this impossible, simply there's no way to do this, I'm just trying to get rid of the less savvy ones (the majority), and not forever, I'm planning to block them for a certain period of time (probably a couple of days or something like that).</p>

Linking with constant variable definition in a header file
|
<p>Suppose I created a header file constants.h and this file contains:</p>
<pre><code>extern const int YEAR = 2011; // definition
</code></pre>
<p>If I tried in a cpp file (MainCPP.cpp) to use this constant after declaring it without defining it and without including the constants.h file as following:</p>
<pre><code>extern const int YEAR; // declaration
int main() {
cout << YEAR << endl;
}
</code></pre>
<p>When I try to do that I get: unresolved external symbol "int const YEAR". On the other hand, if I placed the definition of YEAR within constant.cpp file and done the same in MainCpp.cpp, I will not get the error and the linker will be able to link with YEAR defined within constants.cpp (without including constants.cpp in MainCpp.cpp here too).</p>
<p>Does this mean that the linker can link with source file code but not with header file code unless you explicitly included the header file.</p>

Can we execute multiple commands in the same command prompt launched by python
|
<p>There is an excel file which contains the paths of multiple scenarios. I am using <code>os.system(command)</code> in a for loop. In each iteration, a path is read from excel file and executes the scenario for that path. </p>
<p>My problem is that every time, by using <code>os.system()</code>, a CMD opens, execute one command and close. In next iteration, again second path is read and execute it and CMD close. Here CMD pop-ups again and again. And the system is busy during that period and not able to do other task. I want to execute all the commands(scenario) in one CMD because I would like to minimize it and use the system for other task.</p>
<p>In each iteration, there are two main steps:</p>
<ol>
<li><code>os.chdir(PATH)</code></li>
<li><code>os.system(path of exe+" "+name of config file that is present at PATH")</code></li>
</ol>
<p>Can it be done by using subprocess. If yes please give me some example how it can be implemented?</p>

Sending keys to inactive windows
|
<p>I've been doing java for a couple months now in a software engineering class and I've recently been working on a program that sends text to an inactive or minimized program. Sending it to the active window is a simple matter of importing jna and using the key press function, ex: <code>r.keyPress(KeyEvent.VK_F6);</code>. However, I can't find out how to set the handler to the minimized window and then send the keys there.</p>

Can I use file.readline in a blocking manner? Am I doing this right?
|
<p>I'm trying to write a something that monitors a log file and adds a timestamp when it sees a complete line: </p>
<pre><code>import sys
f = open(sys.argv[1])
if not f:
print 'Failed to open %s' % sys.argv[1]
print sys.argv[1]
import time
try:
while True:
line = f.readline().replace('\n', '')
if not line:
continue
print time.time(), line
except KeyboardInterrupt:
pass
f.close()
</code></pre>
<p>The check for line contents is there because, to my surprise, readlines does not block, but rather returns an empty string for the end of file immediately. </p>
<p>So then, for monitoring files, I have a few questions: Is there any way I can set this to block? I'm seeing empty strings in this loop, is there any chance they don't actually represent an end of line? Do files that are still opened for writing have end of line characters added to them? </p>

Dictionary with List of Values
|
<p>I have a file such as:</p>
<pre><code>a 1
a 2
b 5
c 8
a 9
</code></pre>
<p>I want to add together the second field per key so that I have an aggregate number and therefore a single key:value pair.</p>
<p>With a large dataset I am thinking the best way to go about this would be to create a dictionary that contains a list of values per unique key. Is this the best approach?</p>
<p>How do I set the lists of values per key accurately (below code seems to overwrite values instead of appending)?</p>
<pre><code>dict={}
file=open('foo.txt','r')
lines=file.readlines()
for line in lines:
k, v=line.split()
dict[k]=[v]
</code></pre>
<p>now if i want to take the aggregate numbers populated in first dictionary and compare both the keys and the values against keys and values in another dictionary to determine differences between the two, i can only conclude something like the following:</p>
<p>for i in res.keys():</p>
<pre><code>if res2.get(i):
print 'match',i
else:
print i,'does not match'
</code></pre>
<p>for i in res2.keys():</p>
<pre><code>if res.get(i):
print 'match',i
else:
print i,'does not match'
</code></pre>
<p>for i in res.values():</p>
<pre><code>if res2.get(i):
print 'match',i
else:
print i,'does not match'
</code></pre>
<p>for i in res2.values():</p>

print 'match',i

<pre><code>class Ford extends Car{
}
class Chevrolet extends Car{
}
class Audi extends Car{
}
</code></pre>
<p>Now i have a function called <code>printMessge(Car car)</code> which will print a message of a particular car type. In the implementation i use if statements to test the instance of the classes like this.</p>
<pre><code>public int printMessge(Car car){
if((Ford)car instanceof Ford){
// print ford
}else if((Chevrolet)car instanceof Chevrolet){
// print chevrolet
}else if((Audi)car instanceof Audi){
// print Audi
}
}
</code></pre>
<p>for instance if i call it for the first time with Ford <code>printMessge(new Ford())</code>, it prints the ford message but when i call it with <code>printMessge(new Chevrolet())</code>, i get <strong>EXCEPTION</strong> from the first if statement that Chevrolet cannot be cast to Ford.</p>

Jquery Keyup with Contains to hide Span
|
<p>I am attempting to hide certain elements using the combination of keyup with contains. What I want to do is hide the span elements that do not equal my input values.</p>
<p>For instance, if I input the value 1 the spans containing the values 2 and 3 are hidden, leaving only the span containing the 1 visible. I would also want it to show all of the spans if I then deleted the 1 value from the input</p>
<p>Here is what I have so far, <a href="http://jsfiddle.net/8TXDM/36/" rel="nofollow">http://jsfiddle.net/8TXDM/36/</a></p>

Destruction of class members when destructor is not called
|
<p>In the following code, when <code>ptr</code> is deleted, the destructor for <code>Base</code> is called, but not the destructor for <code>Derived</code> (due to destructor of <code>Base</code> not being virtual).</p>
<pre><code>class Base
{
int b;
};
class Derived : public Base
{
int d;
};
int main(void)
{
Base * ptr = new Derived();
delete ptr;
return 0;
}
</code></pre>
<p>Valgrind reports that the program contains no memory leaks, which i guess is true in the sense that all newed data is deleted in this particular case. <strong>My question is - given that the (default) destructor of <code>Derived</code> is not called, when and how is the memory for <code>d</code> deallocated or reclaimed?</strong></p>

Button subclass with Alpha
|
<p>I'm trying to set the transparency of a button using the API level 10 (so no view.setAlpha).
I wrapped the <code>Button.onDraw</code> calling a <code>Canvas.saveLayerAlpha</code> on a subclass: this works with the text but not with the button background.</p>
<p>I want to make it possible to leave the current button's background management, should I draw the button background myself without calling <code>super.onDraw</code>? How to get a consistent reference to the current button background inside the <code>onDraw</code> extent?</p>

implementing tabs with fragments instead of TabActivity issue
|
<p>I have used this <a href="http://developer.android.com/reference/android/app/TabActivity.html" rel="nofollow">tutorial</a> to implement tabs with fragments instead of TabActivity and it worked greate for some time I have two tabs with ListFragment.
the problem is that suddenly the realTabContent disappeared from the view now I can see TabWidget and change the tab but nothing displayed with no exception and when close the activity with tabs and open again it worked perfectly as expected.
Have any one faced this problem? and what may cause this behaviour?</p>

readlines not reading the last line of the file in python
|
<p>I have a code where I am reading all the lines from the file using readlines function and I am further parsing each line in a list. But when I printed the list I saw that the loop is ignoring the last line in the file. When I inserted a blank line in the file then all the contents are read. can you pls tell me why it is doing that</p>
<pre><code>def readFile1(file1):
f = file1.readlines()
cList1 = []
for line in f:
if re.findall('\n',line):
v = re.sub('\n','',line)
cList1.append(v)
print cList1

php regex form questions

<p>Is it possible to just use this code alone to do two different regex matches?</p>
<p>One reg-ex match for X digits and the other for a given string "CAT" only, or do I need to create two different forms, one for each: X digits and one for the string "CAT"? </p>
<p>Furthermore is there a better php method for this or I am headed in the right direction?</p>
<p>Thank you in advance. </p>
<pre><code><form action ="callself.php" method = "post">
Enter a numeric value:
