i want to resize my window

[Gintaras]

Capture the control (rectangle that shows the number) using the "Find window or control' dialog (the second Drag image). Move it to the top-left corner of the window, and to the top of the Z order. Then resize the window.

int hwnd=id(??? "window name")
SetWindowPos hwnd 0 0 0 0 0 SWP_NOSIZE
siz 100 100 "window name"
