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,

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?

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?

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

Try renaming the project using "Save Project As..." (from the File Menu if this has not changed since C++ Builder 4.0).

That worked, I knew it was something stupid... Thanks a lot.

I'm not a big Borland user so let me understand. You can't change the name of the generated exe or dll without changing the entire project name?

Hi,
How to remove the close button(the one on the upper right)
from a dialog? thanks.
p.c.

Lose the WS_SYSMENU style on your dialog. In dialog editor, uncheck the System Menu option.
