But I thought the WM_SIZE message was sent when the size of the dialog is changed. I have already implemented resizing and reposition on the WM_SIZE, but the controls will always have a position and size relative to the edges of the dialog.
What I am trying to do is resize the Child windows on the dialog, without the dialog itself being affected. In theory one child window would become larger while the other becomes smaller to give space. I'm guessing I would need to place some sort of control bar between the two controls, and handle a mouse event for it. Though I know of no such control.
To make things even more difficult, this is a non MFC project.

There is an article here on CP about a splitter bar for dialogs that does not require the child controls to be CView derived. You can have a look for it here[^]. It may fit your purpose.

Thanks for the suggestions. I have looked through and downloaded all of the splitter bar articles here on CP, all of them use MFC in some form or another. Either the control is derived from CView, CDialog, CSplitter or CWnd. Also after reading through the source codes, I think it would be a great task trying to convert them to a non-MFC project.
There is one article however, which deals with anchoring and resizing controls in non-MFC. Controls are usually anchored against the edges of the dialog, whereas here I would need to anchor the controls against each other, at the same time creating a splitter control.
It's a large task to incorporate into my nearly finished project, maybe I will just leave it for version 2. My boss is already complaining about the time.

I am writing an OpenGL program in visual c++.NET and I am reading a file and using the file as a texture. After I build the program using
Release build" and run the program by double clicking on it in windows explorer, everything works fine, but if I try to run the same program using debug->start from the visual studio menu bar, the texture file won't load. Is this a problem with my code or is visual c++ not loading the file on purpose.
pplshero54 gives his most thanks

Did you install the latest Platform SDK? VirtualAllocEx should be defined in winbase.h which is included by windows.h.
DWORD Address;
to
LPVOID Address;
Address == VirtualAllocEx(
to
Address = VirtualAllocEx(

Thx for your replay. I got rid of the two warnings but am still stuck with the error (error C3861: 'VirtualAllocEx': identifier not found, even with argument-dependent lookup). I have vertion Microsoft Visual C++ .NET. Eny more advice??? please??? thx Glich

From MSDN:
Requires Windows Vista, Windows XP, Windows 2000 Professional, or Windows NT Workstation 4.0.
Server Requires Windows Server "Longhorn", Windows Server 2003, Windows 2000 Server, or Windows NT Server 4.0
That means you need to set WINVER macro to a version that would include VirtualAllocEx declaration.

Thx for your help.
I have tryed it with: "#define WINVER 0x0400" as http://msdn2.microsoft.com/en-us/library/6sehtctf.aspx

Where did you put this definition? It must be defined before windows.h is included. If you use precompiled headers, it is best to put it at the top of stdafx.h. Or just add it to the Project settings.

Thx for your replay.
It still does not work even after I placed the line "#define WINVER 0x0400" as the first line.
More help is needed if posible. Thx again.

Actually, it _WIN32_WINNT that has to be 0x0400. WINVER 0x0400 is the code for windows 95.
#define _WIN32_WINNT 0x0400

i want to check thread is running state or not and if it is running then terminate this thread and start another thread.
anybody have idea about this please share with me:its urgent

To check if thread is still running
<br />
bool IsThreadRunning(HANDLE hThread)<br />
{<br />
DWORD dwExitCode;<br />
::GetExitCodeThread(hThread, &dwExitCode);<br />
return (dwExitCode == STILL_ACTIVE)? true : false;<br />
}<br />
Don't try to terminate the thread using TerminateThread(), either have a flag or event that the thread checks to see if it should terminate gracefully. Frankly I think it's better to reuse the thread...
|
|
|
|
|
To tell if a thread is running or not:
DWORD dwState = WaitForSingleObject(hThread, 0);
switch(dwState)
{
case WAIT_TIMEOUT:
break;
case WAIT_OBJECT_0:
break;
}
The solution using the GetExitCodeThread API has a flaw. From MSDN:
"Warning: If a thread happens to return STILL_ACTIVE (259) as an error code, applications that test for this value could end up in an infinite loop."
In general there is no safe way to forcefully terminate a thread (although this doesn't seem to stop people from doing it) - Doing so, by calling TerminateThread for example, can put the process into an unstable state. One way this happens is as follows:
1. The thread about to be terminated calls an API which enters a critical section by calling EnterCriticalSection.
2. It is terminated before it can call LeaveCriticalSection.
3. Another thread calls the same API and it deadlocks: This API is now broken and any thread calling it will now deadlock.
This really happens and I can tell you from experience that tracking down the problem is not pleasant.
The general solution to this problem is to program the thread so you can arrange for it to exit, typically by signaling an event and then waiting for it to terminate.

Ah. I've never noticed that little caveat since I don't usually return anything other than 0 for my threads. Guess you learn something new everyday...

Returning ZERO signals thats your thread is successfully closed

This need not be the case: The programmer is free to place whatever interpretation on the exit code of a thread that is appropriate for his application. 0 for success is simply the most popular. For example you could use the return code to return the result of a computation.

yeah right... but generally I return results through custom Window Message, as it halp in teo way .. retuning you result plus signally thread is now closed

as my understanding, bar (or space) width is based on unit of mil (1/1000 inch), minimum width of a bar is 7.5 mils.
so barcode should be drawn with MM_HIENGLISH MapMode.
I have checked several barcode software, they draw barcode in many ways with different MapMode, my Question is:
which MapMode is better for drawing barcode?
is MM_HIENGLISH better?
thx

Hi Ganesh_T ,
Can you be more specific ( I press "Esc" all the coontrol opn child dialog also dissappears)
And first question (increase the size of coloumn i list control the borders dissappear)
(I think or I suggestion) that you can derived CListCtrl in your program)
|
|

Suppose we have the Dialog as parent and two dialog as child. On click of button which is placed on parent dialog I am displaying first child dialog.
Now when the focus is on the main Dialog means parent dialog I press "Escape" button the controls which are placed on the dialog box dissappears.
I am not able to find out the problem. Well itried doing different things and setting the properties then also it doesn/t worked.
Cheers
