Maximize form using send/postmessage User32.dll
I have windows application, i need to maximize the window/form.
public const int WM_NCLBUTTONDOWN = 0xA1; public const int HT_CAPTION = 0x2; SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0); and int WM_SIZE = 0x0005; int SIZE_MAXIMIZED = 2; SendMessage(Main, WM_SIZE, SIZE_MAXIMIZED, 0);
Nothing is not working.
Can any show me what the right wat to do it?
