Question

I know I can use MoveWindow to move it but I only want to move the button on the x axis. Thanks.

Answer 1

I figured it out. You can get the button’s (screen) position using GetWindowRect, then you can use ScreenToClient to get it’s location in the form. Example:

RECT buttonScreenRect;
GetWindowRect(hwnd, &buttonScreenRect);

POINT buttonClientPoint;
buttonClientPoint.x = buttonScreenRect.left;
buttonClientPoint.y = buttonScreenRect.top;

ScreenToClient(hwnd, &buttonClientPoint);

MoveWindow(hwnd, 50, buttonClientPoint.y, buttonScreenRect.right - buttonScreenRect.left, buttonScreenRect.bottom - buttonScreenRect.top);

Hope it helps!
