How to restrict user to reduce size of dialog box
-
Hello all, I want to restrict user not to reduce the size of dialog within limits. My dialog box is created in resource editor and class is derived from CDialog. I made the Border property "resizable" and it allows the user to resize the dialog. I want to restrict the user not to reduce the size than certain limit. I write the code in OnSize handler as below
void CMyDlg::OnSize(UINT nType, int cx, int cy) { if (cx < 650) cx = 650; if (cy < 270) cy = 270; CDialog::OnSize(nType, cx, cy); // resize all controls present in the dialog box }But the dialog still can be reduced less than width 650 and height 270. I tried to put "return" if the cx is < 650 and cy < 270. but user can still reduce the size. Can any one suggest how to restict the user? Thanks for your time Ravi -

That's what
OnGetMinMaxInfo()is for. There is an example of it here (in the Extras section).
