Hello there,
I have a dialog based application which has two classes, CMainWindow and CChildWindow. I want to create the ChildWindow from the MainWindow, from inside a thread.
My code snippet.
static UINT CMainWindow::_ShowChildWindow(LPVOID parameter)
{
CMainWindow *mainWind = (CMainWindow*) parameter;
mainWind->ShowChildWindow();
return 0;
}
CMainWindow::ShowChildWindow()
{
m_childwindow = new CChildWindow();
m_childwindow->Create(IDD_CHILDWINDOW);
m_childwindow->ShowWindow(SW_SHOW);
}
CMainWindow::OnButtonShow()
{
AfxBeginThread(_ShowChildWindow,this);
}
The newly created window just blinks and vanishes.
Please help me!
Regards

you need a message loop. See CWinThread::Run for more information.

you dont have the message pump in the _ShowChildWindow
i.e.
MSG msg;<br />
<br />
while (GetMessage(&msg, NULL, 0, 0)) <br />
{<br />
if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) <br />
{<br />
TranslateMessage(&msg);<br />
DispatchMessage(&msg);<br />
}<br />
}

Hello Prakash,

Can you dump the code in the thread funtion here?
Probably the keyboard events are not translated.

Hello Prakash,
Here is the code snippet.
m_chatWindow = new CChatWindow(this);
m_chatWindow->Create(IDD_DIALOG1,GetDesktopWindow());
m_chatWindow->ShowWindow(SW_SHOW);
MSG msg;
HACCEL haccel;
LoadAccelerators(AfxGetInstanceHandle(),AfxGetAppName());
while (GetMessage(&msg, NULL, 0, 0))
{
if (!TranslateAccelerator(m_hWnd, haccel, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
Regards

The problem is with the m_hWnd, i guess i overlooked that.
replace m_hWnd with m_chatWindow->m_hWnd
and let me know if it worked.

Hello prakash,
It did not work. But I got the problem solved by this way
m_chatWindow = new CChatWindow(this); m_chatWindow->Create(IDD_DIALOG1,GetDesktopWindow());
m_chatWindow->ShowWindow(SW_SHOW);
m_chatWindow->RunModalLoop(); //this solved problem.
Regards

oh cool, I am kinda more conversant with win32. Good that you solved it.
RunModalLoop() kinda does what we were doing before but maybe in a correct way.

Hello,
I've just installed Visual Studio 2005 and eagerly I converted the C++ project I'm working on, from Studio 2003 project format to Studio 2005 one.
But I can't get the project to compile. Visual Studio 2005 compiler has been made more ISO compliant so it no longer accepts implicit int declaration.
Thus, I need to convert my project back to Studio 2003 format. But I don't know how.
Can someone help?
Thanks

Your 2003 sln file should still be in your directory. I think all you need to do is load that instead of the converted 2005 sln file (and delete it altogether if you don't want to eventually upgrade) and you should be go to go.
|
|
|
|
|
In the updrade log generated by VC 2005 it is said there is a backup sln file in the project directory.
It is called myproject.sln.old but I can't find it even in the hidden files.
Do you have any idea?

Thanks for your reply.
I wish I had read that article before upgrading.
Now I just cant compile my project.

So why don't you go ahead and fix it? Why leave bad code in your source?

In my project I'm using a library with thousands of code lines. And the real problem is that library. I don't dare mess with such a huge amount of code I've not written myself.
Anyway thanks for replying.

Hello,
Did you make a backup? VS 2005 asks this before it converts the file.
Anyway, as Nishant already said it: fix the errors and use the better compiler. The standard conformance is far better than any previous compiler written by Microsoft.
