The GetDlgItemText function retrieves the title or text associated with a control in a dialog box.
hwndDlg
Identifies the dialog box that contains the control.
idControl
Specifies the integer identifier of the dialog-box item whose caption or text is to be retrieved.
lpsz
Points to the buffer to receive the text.
cchMax
Specifies the maximum length (in characters) of the string to be copied to lpsz. If the string is longer than cchMax, it is truncated.
The return value specifies the number of characters copied to the buffer, not including the terminating null character, if the function is successful. Otherwise, it is zero.
The GetDlgItemText function sends a WM_GETTEXT message to the control.
The GetDlgItemText function may be used as either a wide-character function (where text arguments must use Unicode) or an ANSI function (where text arguments must use characters from the Windows 3.x character set installed).
