changing size of dialog box
Hi Dave,
The reason the dialog went to the upper left hand corner is because
you used GetClientRect. You need to use GetWindowRect if you want to
keep it in the same place.
Below is a sample of the code I use when I want to resize a dialog
// Create local CRect variable to hold Dialog size
CRect rRect;
// Get the Dialog size
GetWindowRect(rRect);
//Make sure values are positive
rRect.NormalizeRect();
// x position of dialog top left corner
int lx = rRect.left;
// y position of dialog top left corner
int ly = rRect.top;
// width of dialog
int lcx = rRect.right - rRect.left;
// height of dialog
int lcy = rRect.bottom - rRect.top;
// Make sure I subtracted right. Don't want negative values
if(lcx < 0)
lcx = 0 - lcx;
if(lcy < 0)
lcy = 0 - lcy;
//Want to decrease height by 40
lcy = lcy - 40;
// Redraw the dialog in same place but shorter
SetWindowPos(&wndTop, lx, ly, lcx, lcy, SWP_SHOWWINDOW);
