When we want a form to keep a form on the top of the desktop, you can define a form.
Formstyle
Property, keeps the form on the top. However, after using this method, the form will flash when switching the form of the form. In order to avoid flashing when switching the form mode, you can use
Windows API
function
SetwindowPOS
To solve this problem, the method is as follows:
Setwindowpos (Form1.handle, Hwnd_topmost, Form1.LiD, Form1.top, Form1.Width, Form1.Height, 0);
Instead of "Form1" with the actual form name, you can set the form to keep the form to the top of the desktop. To switch the form back to the normal form, call the following command:
Setwindowpos (Form1.Handle, Hwnd_Notopmost, Form1.Width, Form1.Height, 0);
