I am developing a server client application, where Client will send a huge amount of data to server through internet. However I have done some asynchronous socket programing before. Can I use same code here ?
Hi Geeks,
I downloaded the qt embedded demo source code recently on my linux machine. Following are the outcomes during running of the program
I compiled it statically on my x86 machine and run the application on x86 machine it runs fine. But when i took the statically compiled binary file to other machine with Atom platform It run with some missing widgets. I found that the plugins cant be ported with static compilation. Can anybody tell me is it true? If no can anybody tell me the steps for it?
I compiled it dynamically with shared libraries. Then got an executalbe on linux. I did "ldd MyAppName". It show me the shared library files it is using. But I dont know how to package these. Can anybody tell me the steps to package it?
I checked in the article on deploying qt applications on X11-linux platforms. But its not complete. Can anybody give me the detailed steps?
Any help will be appreciated......
Like every other web developer on the planet, I have an issue with users double clicking the submit button on my forms. My understanding is that the conventional way to handle this issue, is to disable the button immediately after the first click, however when I do this, it doesn't post.
I did do some research on this, god knows there's enough information, but other questions like Disable button on form submission, disabling the button appears to work. The original poster of Disable button after submit appears to have had the same problem as me, but there is no mention on how/if he resolved it.
Here's some code on how to repeat it (tested in IE8 Beta2, but had same problem in IE7)
My aspx code
<%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<script language="javascript" type="text/javascript">
function btn_onClick()
{
var chk = document.getElementById("chk");
if(chk.checked)
{
var btn = document.getElementById("btn");
btn.disabled = true;
}
}
</script>
<body>
<form id="form1" runat="server">
<asp:Literal ID="lit" Text="--:--:--" runat="server" />
<br />
<asp:Button ID="btn" Text="Submit" runat="server" />
<br />
<input type="checkbox" id="chk" />Disable button on first click
</form>
</body>
</html>
My cs code
using System;
public partial class _Default : System.Web.UI.Page
{
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
btn.Click += new EventHandler(btn_Click);
btn.OnClientClick = "btn_onClick();";
}
void btn_Click(object sender, EventArgs e)
{
lit.Text = DateTime.Now.ToString("HH:mm:ss");
}
}
Notice that when you click the button, a postback occurs, and the time is updated. But when you check the check box, the next time you click the button, the button is disabled (as expected), but never does the postback.
WHAT THE HECK AM I MISSING HERE???
Thanks in advance.
I am looking to profile my web application on Android for starts...what is the best way to get the kind of information that a tool like Web Inspector would give me on the desktop? Since I cannot use Web Inspector or Speed Tracer on the mobile device...how can I get such data/info ?
I am running a dell poweredge 1950 with 4 nic cards. 1 is bonded to SAN #1 on 192.168.90.xx. The second SAN is on a separate network - 192.168.7.xx The network adapter can view the ip range of the san and the NIC can be pinged from 192.168.7.xx range. vswitch1 and vswitch2 are configured identically except for the ip address. The second SAN has been added to the iscsi software adapter but the SAN is never recognized. I can connect to the SAN from other machines on the local network. Is there something else that needs to be configured for the iscsi software adapter to know which vswitch to use?
Hi, I'm working on how my company does documentation (especially programming documentation). I'd like to be able to synchronize sections of different Word documents, such that if a section in one document changes, the change is reflected in the other document, and vice versa. Is there a way to do this with Word, and if not, is there some word processing program that is good at this?
I am trying to understand why any import can be referenced using the importing module, e.g
#module master.py
import slave
and then
>>>import master
>>>print master.slave
gives
<module 'slave' from 'C:\Documents and Settings....'>
What is the purpose of the feature? I can see how it can be helpful in a package's __init__.py file, but nothing else. Is it a side effect of the fact that every import is added to the module's namespace and that the module's namespace is visible from the outside? If so, why didn't they make an exception with data imported from other modules (e.g don't show it as part of the module's namespace for other modules)?
I have a menu click event that looks something like this....
Public Sub ToolbarManager_ToolClick(sender as Object, e as EventArgs)
Case "New"
CreateNewFile()
Case "Save"
SaveCurrentFile()
Case "Exit"
ExitApp()
Case.......
etc...
etc...
End Sub
This strikes me as being 'ugly' - but I'm unsure of the 'best' way or the most appropriate way to clean it up.
if IDE by default adding ; at end. should i remove?
selector {property:value;property:value;property:value;property:value;}
I read on an article semicolon not required at end.

I am developing a network based application. I need to retrieve data through internet. The scenario is like this - a client machine will send data through internet to the server machine and data size will be big enough. So should i use simple TCP/IP socket concept or else? Because i never did a socket program which will retrieve data through internet..... Any suggestion will be very helpful....... Thanks.

I am writing a small windows script in javascript/jscript for finding a match for a regexp with a string that i got by manipulating a file.

Hi,
I'm creating a COM dll and it will be loaded by VBA. However, I noticed that for every excel instance (workbook), a new COM object is loading to memory. But I need to maintain single COM state irrespective of number of Excel instances exists.
Please help me achieve this purpose .
Thank you
I have a computation task which is split in several individual program executions, with dependencies. I'm using Condor 7 as task scheduler (with the Vanilla Universe, due do constraints on the programs beyond my reach, so no checkpointing is involved), so DAG looks like a natural solution. However some of the programs need to run on the same host. I could not find a reference on how to do this in the Condor manuals.
Example DAG file:
JOB A A.condor
JOB B B.condor
JOB C C.condor
JOB D D.condor
PARENT A CHILD B C
PARENT B C CHILD D
I need to express that B and D need to be run on the same computer node, without breaking the parallel execution of B and C.
Thanks for your help.
I have the following type in wsdl (it is generated by third party tool):
<xsd:complexType name="IntArray">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Elements" type="xsd:int" />
</xsd:sequence>
</xsd:complexType>
Sometimes Visual Studio generates:
public class IntArray : System.Collections.Generic.List<int> {}
And sometimes it doesn't generate any proxy type for this wsdl and just uses int[].
Collection type in Web Service configuration is System.Array.
What could be the reason for such upredictable behavior?
Edited:
I found the way how I can reproduce this behavior.
For examle we have two types:
<xsd:complexType name="IntArray">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Elements" type="xsd:int" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="StringArray">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Elements" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
VS generates:
public class IntArray : System.Collections.Generic.List<int> {}
public class StringArray : System.Collections.Generic.List<string> {}
Now I change StringArray type:
<xsd:complexType name="StringArray">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Elements" type="xsd:string" />
<xsd:any minOccurs="0" maxOccurs="unbounded" namespace="##any" processContents="lax" />
</xsd:sequence>
<xsd:anyAttribute namespace="##any" processContents="lax"/>
</xsd:complexType>
VS generates proxy type for StringArray only. But not for IntArray.
I'm trying to set up an NSCollectionView (I have done this successfully in the past, but for some reason it fails this time).
I have a model class called "TestModel", and it has an NSString property that just returns a string (just for testing purposes right now). I then have an NSMutableArray property declaration in my main app delegate class, and to this array I add instances of the TestModel object.
I then have an Array Controller that has its Content Array bound the app delegate's NSMutableArray. I can confirm that everything up to here is working fine; NSLogging:
[[[arrayController arrangedObjects] objectAtIndex:0] teststring]
worked fine.
I then have all the appropriate bindings for the collection view set up, (itemPrototype and content), and for the Collection View Item (view). I then have a text field in the collection item view that is bound to Collection View Item.representedObject.teststring. However NOTHING displays in the collection view when I start the app, just a blank white screen. What am I missing?
UPDATE: Here is the code I use (requested by wil shipley):
// App delegate class
@interface AppController : NSObject {
NSMutableArray *objectArray;
}
@property (readwrite, retain) NSMutableArray *objectArray;
@end
@implementation AppController
@synthesize objectArray;
- (id)init
{
if (self = [super init]) {
objectArray = [[NSMutableArray alloc] init];
}
return self;
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
TestModel *test = [[[TestModel alloc] initWithString:@"somerandomstring"] autorelease];
if (test) [objectArray addObject:test];
}
@end
// The model class (TestModel)
@interface TestModel : NSObject {
NSString *teststring;
}
@property (readwrite, retain) NSString *teststring;
- (id)initWithString:(NSString*)customString;
@end
@implementation TestModel
@synthesize teststring;
- (id)initWithString:(NSString*)customString
{
[self setTeststring:customString];
}
- (void)dealloc
{
[teststring release];
}
@end
And then like I said the content array of the Array Controller is bound to this "objectArray", and the Content of the NSCollectionView is bound to Array Controller.arrangedObjects. I can verify that the Array Controller has the objects in it by NSLogging [arrayController arrangedObjects], and it returns the correct object. Its just that nothing displays in the NSCollectionView.
UPDATE 2: If I log [collectionView content] I get nothing:
2009-10-21 08:02:42.385 CollViewTest[743:a0f] (
)
The problem is probably there.
UPDATE 3: As requested here is the Xcode project:
http://www.mediafire.com/?mjgdzgjjfzw
Its a menubar app, so it has no window. When you build and run the app you'll see a menubar item that says "test", this opens the view that contains the NSCollectionView.
Thanks

A bit weird... ...if running in IE8 quirks mode, the table added by the following code doesn't render. Can anyone tell me why, because it is not obvious to me..?

I've downloaded, unzipped and setup Eclipse 3.4.2 with some plugins (noteable, EPIC, Clearcase, QuantumDB, MisterQ).
Now I find when I'm editing Java projects the code completion is not working. If I type String. and press ctrl-space a popup shows "No Default Proposals" and the status bar at the bottom shows "No completions available".
Any ideas?
Thanks....
In the spirit of the "Perl Preamble" where a script works properly whether executed by a shell script interpreter or the Perl interpreter...
I have a Perl script which contains an embedded HTML document (as a "heredoc"), i.e.:
#!/usr/bin/perl
... some perl code ...
my $html = <<'END' ;
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
... more HTML ...
</html>
END
... perl code that processes $html ...
I would like to be able to work on the HTML that's inside the Perl script and check it out using a web browser, and only run the script when the HTML is the way I want. To accomplish this, I need the file to be openable both as an HTML file and as a Perl script.
I have tried various tricks with Perl comments and HTML comments but can't get it quite perfect. It doesn't have to be "strictly legal" HTML... just displayable in a browser with no (or minimal) Perl garbage visible.
