Excuse me: What is the role of WM_SIZE?

error_log

.if eax == WM_SIZE
invoke GetClientRect, hWinMain, addr @stRect
invoke MoveWindow, hWinEdit, 0,0, @ stRect.right, @ stRect.bottom, TRUE


What is the purpose of this, I removed it, the program can still run normally?

Oh? Drag the border of the main window to change the size of the window to see how the two programs behave differently before and after you modify it.

error_log

No adverse reactions

Look at the code above, there should be an edit type child window in the main window. The child window also behaves the same?

error_log

Oh, it's for the child window,
