Why dont you do a GetWindowText(.) from where ever you want the text from. It is also possible to change the position in the z-order of the newly created window by modifying the hwndInsertAfter member of the CBT_CREATEWND structure.Īs explained above, you have intercepted the call just before the window was created, and so you dont get the text. It is possible to send messages to the newly created window, although it has not yet received WM_NCCREATE or WM_CREATE messages. The hook procedure returns zero, the window is created normally.Īt the time of the HCBT_CREATEWND notification, the window has been created, but its final size and position may not have been determined and its parent window may not have been established. Returns NULL, but the WM_DESTROY message is not sent to the window. If the hook procedure returns a nonzero value, the system destroys the window the CreateWindow function The system calls the hook procedure before sending the WM_CREATE or WM_NCCREATE message Please remember to mark the replies as answers if they help and unmark them if they provide no help.Ī window is about to be created.

The window manager handles character conversion for you ( SendMessageA vs SendMessageW) so you don. Some applications dynamically handle the WMTEXT messages. GetWindowTextW is always able to retrieve this text. Most top-level windows store their text here. And here is code sample about this idea: The window text can come from two places: Unicode text 'stored internally in the HWND'.
