No code example is currently available or this language may not be supported.
- hWnd IntPtr
-
A handle to the window or control containing the text.
- lpString StringBuilder
-
The buffer that will receive the text.
If the string is as long or longer than the buffer, the string is truncated and terminated with a null character.
- cch Int32
-
The maximum number of characters to copy to the buffer, including the null character.
If the text exceeds this limit, it is truncated.
Int32
If the function succeeds, the return value is the length, in characters, of the copied string,
not including the terminating null character.
If the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid,
the return value is zero.
