SetIcon Error / Exception
-
I have a MDI application where, i am using a picture control to load icons of leds. The goal is to load the picture control with ICON that look like leds green and red. However, I am getting a Debug Assertion Failed where i set the new icon value. iconPitchActiveFault is CStatic control variable for a ICON void Lenze8200_Dlg::OnShowWindow(BOOL bShow, UINT nStatus) { CFormView::OnShowWindow(bShow, nStatus); //UpdateData(TRUE); HICON Red_ON; HICON Red_OFF; HICON Green_ON; HICON Green_OFF; // TODO: Add your message handler code here Red_ON = AfxGetApp()->LoadIcon(IDI_RED_ON_LED); Red_OFF = AfxGetApp()->LoadIcon(IDI_OFF_LED); Green_ON = AfxGetApp()->LoadIcon(IDI_GREEN_ON_LED); Green_OFF = AfxGetApp()->LoadIcon(IDI_OFF_LED); ******** The exceptions shows up here ************** m_iconPitchActiveFault.SetIcon( Red_OFF ); }

Is it an exception or an assertion?

As soon as a window is created, many different messages, including
WM_SHOWWINDOWwill start flying. But just because the parent window is created, doesn't mean its children are also alive and well. You can avoid this problem by making liberal use ofIsWindow():if (::IsWindow(m\_iconPitchActiveFault.m\_hWnd)) m\_iconPitchActiveFault.SetIcon( Red\_OFF );Best wishes, Hans

How do you make m_iconPitchActiveFault?
