Re: Debug Assertion Failed, with SetTimer
A couple of more things wincore.cpp line 311 is different for different
versions of Visual C++, you might want to specify which version you are
using.
You can also find out where this is happening by pressing Retry when the
assert happens and walk up the callstack to find what line in your code is
causing the problem.

Are you 100% sure that this is happening when SetTimer is called? Did you
put a breakpoint in OnStart and step through it?
SetTimer never even gets near the Attach method, so I don't think that it
is SetTimer that is causing the problem.

Hi,
I got this error when call the SetTimer (..) for the 2nd time:
Debug Assertion Failed
File: wincore.cpp
Line: 311
Basically, I call SetTimer
void CChildDlg: OnStart( )
{
// do something
...
SetTimer(100, 500, NULL);
}
void CChildDlg: OnEnd( )
{
KillTimer(100);
...
// do something
}
Click Start Button, timer running OK, then click End to stop timer,
then click Start button, and I get the Debug Assertion Failed.
When debug, it points to:
BOOL CWnd::Attach(HWND hWndNew)
{
ASSERT(m_hWnd == NULL); // only attach once, detach on destroy
ASSERT(FromHandlePermanent(hWndNew) == NULL);
// must not already be in permanent map
if (hWndNew == NULL)
return FALSE;
CHandleMap* pMap = afxMapHWND(TRUE); // create map if not exist
ASSERT(pMap != NULL);
pMap->SetPermanent(m_hWnd = hWndNew, this);
#ifndef _AFX_NO_OCC_SUPPORT
AttachControlSite(pMap);
#endif
return TRUE;
}
Can anyone help ?
I changed to Release Version, also same issue
