Re: Debug Assertion Failed, with SetTimer
O, and by the way, if you're using VC6 make sure that all your event
handlers have correct function signature. VC2002+ will check that for you.

Don't access your dialog from another thread.

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
