This following builds but I see no effect in my test form:
protected override void OnClick(System.EventArgs e)
{
base.OnClick(e);
}

If you don't want the radio button to process the OnClick event, remove the base.OnClick(e) call from your code.

make it like this

//base.OnClick(e);
}

Hi Josh,
I think the Code Project site has reformatted your code or else it's identical previous suggestions.

Hi,
I have a listview (property View is "Details"). I set the sorting property true. Is it possible that the sorting is made after the second column and not the first one (like it does now)?
Thanks!
|
|
|
|
|
Yes, it's possible. But it's not easy. You have to handle the ColumnClick event of the ListView, provide you own sorting mechanism...
But wait, actually it's easy  Simply use the ListViewSortManager class from the following article:
http://www.codeproject.com/cs/miscctrl/lvsortmanager.asp[^]
I hope it helps!

hi all,
I would want to allow the opening of particular system dialog from my c# application. I heave find this article written in mfc/c++, is possible to written a similar class in c# ? I have tried but my solution not allow to open a system dialog as modal.
this is my class:
using System;<br />
using System.IO;<br />
using System.Diagnostics;<br />
using System.ComponentModel;<br />
using System.Windows.Forms;<br />
using System.Runtime.InteropServices;<br />
<br />
namespace System<br />
{<br />
public class SystemDialogs<br />
{<br />
public SystemDialogs()<br />
{<br />
<br />
}<br />
<br />
public enum Dialogs<br />
{<br />
SD_FORMAT = 1,<br />
SD_INTERNET_OPTIONS = 2,<br />

SD_DEVICE_MANAGER = 16,<br />
}<br />
<br />
public static void ShowDialog(SystemDialogs.Dialogs Dialog)<br />
{<br />
string[] Args = new string[16]<br />
{<br />
"Shell32.dll SHFormatDrive",<br />
"Shell32.dll Control_RunDLLA inetcpl.cpl 0",<br />

Is there a function that will automatically turn a relative path into an abosolute one? I could use Application.ExecutablePath and iterate up a level for each ..\ in the relative one if not but I'd just as soon not reinvent the wheel.

Have you looked at the Path.GetFullPath( string ) method?
From the documentataion:
Returns the absolute path for the specified path string.
For example, if I write a console application that contains the following statement as the sole entry in the Main function:
Console.WriteLine( System.IO.Path.GetFullPath( "..\\.\\moo.txt" ) );
and run it from the Command window, I'd get:
c:\dir1\dir2\dir3\dir4> RunGetFullPathTest.exe
c:\dir1\dir2\moo.txt
c:\dir1\dir2\dir3\dir4>

Hi!
I would like to make a control that can contain other controls. I know how to accomplish this by inheriting the Panel. Next problem is how to reserve parts of the control for headers etc., ie restrict the ClientRectangle to a part of the control. Is this possible.
BR

There may be other ways to do this.
What if you change the location of the child control in the ControlAdded event if the child control is drawn in the Header area.

Hi all,
I'm writing an assembly which processes incoming messages from a tcp socket and fires an event if a relevant message is received. I understand the need to fire the message on the appropriate thread, but was hoping that instead of the consumer of my client having to use begininvoke, i could somehow pass in the thread I want the event to fire on as a parameter and have the control handle the event without 'knowing' which thread it came from.
Is this at all possible, or have i missed what is going on here.
Thanks for any help anyone gan give,
Russell

Does that come from the need of modifying the UI on the thread it was created? You usually only have one UI thread so writing formname.BegingInvoke isn't too complicated.
If you are talking about worker threads that only process the events without touching the UI, I usually just queue them in a work queue. I wrote a class that create a delegate that do it transparently from another one. I really should write an article on that.
You can mix both technique to have both UI and direct delegate on the same event, just make a class like this:
class UIDelegate<br />
{<br />
private ISynchronizeInvoke mSync;<br />
private Delegate mDelegate;<br />
<br />
public static Delegate Create( ISynchronizeInvoke sync, Delegate d )<br />
{<br />
UIDelegate newd = new UIDelegate( sync, d );<br />
return Delegate.CreateDelegate( d.GetType(), newd , "Handler" );<br />
}<br />
<br />
private UIDelegate( ISynchronizeInvoke sync, Delegate d )<br />
{<br />
mSync = sync;<br />
mDelegate = d;<br />
}<br />
<br />
private void Handler( object sender, EventArgs arg )<br />
{<br />
if ( mSync.InvokeRequired )<br />
{<br />
mSync.BeginInvoke( mDelegate, new object[]{ arg } );<br />
}<br />
else<br />
{<br />
mDelegate.DynamicInvoke( new object[]{ arg } );<br />
}<br />
}<br />
}<br />
<br />
myObjectOnAnotherThread.AnEvent += (EventHandler)UIDelegate.Create( theForm, new EventHandler(TheFunction) );
I am trying to get the indentation right but it seems I cant figure it out and I need to go home.
I did not compile it, just wrote what I remember from the class I have at home.
That will hide the ugly forwarding into the UIDelegate class this was other classes do not need to be aware of UI things to do their job correctly.
I use the same principle to queue the request and execute it later on my worker threads.

I need to implement YesToAll,NoToAll feature with messagebox. Say I have several images, when user selects ClearAll...I want to show Prompt with Yes,No,YesToall,NoToAll..Yes would delete current image and prompt with next image, No would skip current image and prompt with next image
How can it communicate with business logic? I have to pop up messagebox each time if user selects yes or no for image
Thanks for anticipation.
Regards,
MaulikCE

You need to a create a form with that functionality. Messagebox doesn't provide any way to do it.

Hi Everyone,
I went through a article "Build solution from command line or with contexmenu item with Microsoft VS.NET" and i tried the code in VS.Net 2003"
Link: www.codeproject.com/dotnet/builditemincontextmenu.asp
written by "Jerry Maguire".
Using that application i tried to create dll for a solution file created in VS.Net2003, Its working fine.
But when tried it for a solution file written in VS 2005, it raises error.
Should i change anything from that given code?
Plz help me to solve this issue.
Thanks & Regards,
Dhivya N.

I can't imagine why it wouldn't be visible, but to get around the problem just add a new text file, call it App.config, and add the following text to it:
="1.0"="utf-8"
<configuration>
</configuration> It will behave the correct way. There's nothing special about App.config when it's being edited.
Share and enjoy.
