Try Debug|Break when application hangs. You should be able to have a look at the other threads' stacks - this information may be helpful.

The other threads have nothing to do with the GUI though. In fact, when the app hangs, the other (worker threads) haven't even been started.

But what's on the stack when you Debug|Break? A call to ::CreateDialogIndirect or something else?

Funny -- this has been a bug for a very long time now, and now that I'm trying to reproduce it so I can see what's on the stack, everything works perfectly. You gotta love it...

Hi
I want to create an SDI-app with two splitter-windows.
It should look like this:
|--------------------|
| |
| |
| C(Rich)EditView |
| |
| |
|--------------------|
| CView |
|--------------------|
How can I realize it?`I already wrote some code, but unfortunately the MainFrame looks very weird and has some GUI-bugs. If someone could help me improve this code:
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
CRect cr;
GetClientRect( &cr );
if ( !m_mainSplitter.CreateStatic( this, 2, 1 ) )
{
MessageBox( "Fehler beim Erstellen der einzelnen Fenster!", "Fehler beim Initialisieren!",MB_OK | MB_ICONERROR );
return FALSE;
}
if ( !m_mainSplitter.CreateView( 0, 0, RUNTIME_CLASS(CMyAppView),CSize( cr.Width(), cr.Height()), pContext ) )
{
MessageBox( "Fehler beim Erstellen der einzelnen Fenster!", "Fehler beim Initialisieren!",MB_OK | MB_ICONERROR );
return FALSE;
}
if ( !m_mainSplitter.CreateView( 1, 0, RUNTIME_CLASS(CDebugView),CSize( cr.Width(), cr.Height()), pContext ) )
{
MessageBox( "Fehler beim Erstellen der einzelnen Fenster!", "Fehler beim Initialisieren!",MB_OK | MB_ICONERROR );
return FALSE;
}
m_initSplitters = TRUE;
return CFrameWnd::OnCreateClient(lpcs, pContext);
}
void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
CFrameWnd::OnSize(nType, cx, cy);
CRect cr;
if ( m_initSplitters && nType != SIZE_MINIMIZED )
{
m_mainSplitter.GetClientRect( &cr );
m_mainSplitter.SetRowInfo( 0, cy / 2, 0 );
m_mainSplitter.SetRowInfo( 1, cy / 2, 0 );
m_mainSplitter.SetColumnInfo( 0, cy, 0 );
m_mainSplitter.RecalcLayout();
}
}
thanks in advance

What are these GUI-bugs?

You shouldn't call CFrameWnd::OnCreateClient in CMainFrame::OnCreateClient. Just return TRUE. CFrameWnd::OnCreateClient creates additional view using pContext. Your application has 3 (not 2) views and this is where problems begin.

I have a list box that I am using to display a status log. When the visible list box fills up, I would like the list box to scroll down with each new entry. How can I accomplish this?

I use this
CListBox::SetTopIndex()

Hi
I'm just writing an SDI-application with Splitter-Windows.
I have created the splitter-windows in the function BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
Now I need to set the Row-and col-information in the OnSize-function.
But there the application crashes:
void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
CFrameWnd::OnSize(nType, cx, cy);
CRect cr;
if ( m_initSplitters && nType != SIZE_MINIMIZED )
{
m_mainSplitter.SetRowInfo( 0, cy, 0 );
m_mainSplitter.SetRowInfo( 1, cy, 0 );
m_mainSplitter.SetColumnInfo( 0, cx, 0 );
m_mainSplitter.SetColumnInfo( 1, cr.Height() - 150, 0 );
m_mainSplitter.RecalcLayout();
}
}
it crashes in file winsplit.cpp at this point:
void CSplitterWnd::SetRowInfo(int row, int cyIdeal, int cyMin)
{
ASSERT_VALID(this);
ASSERT(row >= 0 && row < m_nMaxRows);
ASSERT(cyIdeal >= 0);
ASSERT(cyMin >= 0);
->>>>>> m_pRowInfo[row].nIdealSize = cyIdeal; <------- here's the crash
m_pRowInfo[row].nMinSize = cyMin;
}
can someone explain me what's going on here?
thanks in advance

Hi,
check the splitter window handle value before change the size of splitter window,
you can try the following way
void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
CFrameWnd::OnSize(nType, cx, cy);
//i added only the following condition
if ( m_initSplitter.m_hWnd != NULL )
{
CRect cr;
if ( m_initSplitters && nType != SIZE_MINIMIZED )
{
m_mainSplitter.SetRowInfo( 0, cy, 0 );
m_mainSplitter.SetRowInfo( 1, cy, 0 );
m_mainSplitter.SetColumnInfo( 0, cx, 0 );
m_mainSplitter.SetColumnInfo( 1, cr.Height() - 150, 0 );
m_mainSplitter.RecalcLayout();
}
}
}
bye,
J.Mahesh

Thanks!
I just forgot to tell the app that all windows have been created sucsessfully (i.e. I forgot to set the variable m_initSplitters to TRUE)
works well, but I still have problems with the app (view thread above "CSplitterWnd")

How can I intercept the 'Enter' key before it reach a button.
I tried WM_CHAR in the PreTranslate function, but this works only for alphanumerics and not the 'Enter' key.
Thank You

Try the IDOK message.. you are using a dialog, aren't you?
You could also try the WM_KEYDOWN message.

Subject How to send message WM_RBUTTONDOWN?

I want to send the WM_RBUTTONDOWN from a console program to a MFC application window. I did it like this:
::SendMessage(destHwnd, WM_RBUTTONDOWN, 0, MAKELPARAM(point.x,point.y))
But, the MFC application window can't get the msg at all. What's wrong?
PostMessage desn't work also.
Thank you,

The obvious problem could be a wrong handle.
Use Spy++ and debugger to see if your handle is ok.

Have you used FindWindow to get the proper destHwnd?

I have defined inside the DLL a common global variable to store the time (time_t). Well, inside the hook CBTProc i read always a value of 0 from the variable and out of the DLL i can read it correctly (with a function that return it).
What's wrong?
Please help me and thanks in advance.

Probably you forgot to place global variable into a shared data section. BTW: how are you accessing this variable 'outside the DLL'?

I'm new to MFC programming but I'm slowly learning!
I'm writing a program that minimizes to the systray, I can minimize from the menubar but not from the minimize button in the upper right corner!
What message is sent when that button is pushed and where am I supposed to catch it?
Eyses

Use CMainFrame::OnSize
if (nType == SIZE_MINIMIZED)
//Handle the minimized window
else
//don't do anything.
Good luck,
Frank

I'm working on a project in BC++B5 and up until now when compiled the output application is named wb.exe. I want to change what the executable name is when compiled. Any ideas?
Aaron

|
|
|
If C++ Builder 5.0 is the same as 1.0 which I used. The Project Name is the name of the executable.
if your project is myprj.mak
the executable name is myprj.exe
|
|
|
|
|
They no longer use *.mak, it is now *.bpr for your project. Good idea, but I've tried that already and it doesn't work.
Thanks,
Aaron
