I'm using MFC for Visual Studio 2003. I have an Edit Control with ID IDC_COMMENT_EDIT
.
In the following code, after my first call to GetClientRect
, I don't expect the value of rc
to change.
CWnd* pWnd = GetDlgItem(IDC_COMMENT_EDIT);
if (pWnd != NULL)
{
RECT rc;
pWnd->GetClientRect(&rc);
pWnd->MoveWindow(&rc, TRUE);
pWnd->GetClientRect(&rc);
}
rc.top
and rc.left
are 0
all the way through, as expected.
However:
GetClientRect
, I get rc.bottom == 52
, and rc.right == 575

After the second call to GetClientRect
, I get rc.bottom == 48
, and rc.right == 571
.
Does anyone have any idea what is going on?
Your call to MoveWindow is resizing. You need to use GetWindowRect instead of GetClientRect.
The client rect only includes the client area
which is the non windows elements (such as border) of the window.
The client rect doesn't include the window borders, but MoveRect expects a rectangle that includes the borders. Use GetWindowRect instead.
