This function copies the text of the specified window's title bar — if it has one — into a buffer. If the specified window is a control, the text of the control is copied. The specified window must be on a Windows Embedded CE–based remote device.
int CeGetWindowText ( HWND hWnd, LPWSTR lpString, int nMaxCount );
The length, in characters, of the copied string, not including the terminating null character, indicates success. Zero indicates that the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid. To get extended error information, call CeGetLastError and CeRapiGetError.
This function cannot retrieve the text of an edit control in another application.
