Re: SetWindowPos unhandled exception only in release system

Tech-Archive recommends: Fix windows errors by optimizing your registry

put a try catch block around the code and see what the exception is


try
{
CRect ParentRect;
GetParent()->GetClientRect (&ParentRect);

CRect OurRect;
GetClientRect (&OurRect);

// compute position for this window

int Column = (m_Number - 1) % MAX_COLUMNS;
int Row = (m_Number - 1) / MAX_COLUMNS;

int xOffset = X_OFFSET_START + (Column * (OurRect.Width() +
COLUMN_SPACE));
int yOffset = Y_OFFSET_START + (Row * (OurRect.Height() +
ROW_SPACE));

SetWindowPos(GetParent(),
ParentRect.left + xOffset,
ParentRect.top + yOffset,
0, 0, // ignores size arguments
SWP_NOSIZE | SWP_NOZORDER);
}
catch (CException *E)
{
E->ReportError();
}

I have a class derived from CDialog. In its OnInitDialog(), I call
SetWindowPos() as shown below. Under debug, it works fine. In the
release version, I get an unhandled exception access violation in
MFC42.DLL.

Any ideas?

Thanks so much.

BOOL CDlgPortStatus::OnInitDialog()
{
CDialog::OnInitDialog();

// place the window based on its number

CRect ParentRect;
GetParent()->GetClientRect (&ParentRect);

CRect OurRect;
GetClientRect (&OurRect);

// compute position for this window

int Column = (m_Number - 1) % MAX_COLUMNS;
int Row = (m_Number - 1) / MAX_COLUMNS;

int xOffset = X_OFFSET_START + (Column * (OurRect.Width() +
COLUMN_SPACE));
int yOffset = Y_OFFSET_START + (Row * (OurRect.Height() +
ROW_SPACE));

SetWindowPos(GetParent(),
ParentRect.left + xOffset,
ParentRect.top + yOffset,
0, 0, // ignores size arguments
SWP_NOSIZE | SWP_NOZORDER);
