int GetDlgItemText( int nID, LPTSTR lpStr, int nMaxCount ) const; int GetDlgItemText( int nID, CString& rString ) const;
- Specifies the integer identifier of the control whose title is to be retrieved.
- Points to the buffer to receive the control's title or text.
- Specifies the maximum length (in bytes) of the string to be copied to lpStr. If the string is longer than nMaxCount, it is truncated.
- A reference to a CString.
Specifies the actual number of bytes copied to the buffer, not including the terminating null character. The value is 0 if no text is copied.
The GetDlgItemText member function copies the text to the location pointed to by lpStr and returns a count of the number of bytes it copies.
