Dialog Functions: Determine whether the specified message is intended for one of the currently displayed modeless dialog boxes, or a specific dialog box.
USE IFLOGM
result = DLGISDLGMESSAGE (mesg)
result = DLGISDLGMESSAGEWITHDLG (mesg, dlg)
mesg |
(Input) Derived type T_MSG. Contains a Windows message. |
dlg |
(Input) Derived type dialog. Contains dialog box parameters. The components of the type dialog are defined with the PRIVATE attribute, and cannot be changed or individually accessed by the user. |
The result type is LOGICAL(4). The result is .TRUE. if the message is processed by the dialog box. Otherwise, the result is .FALSE. and the message should be further processed.
DLGISDLGMESSAGE must be called in the message loop of Windows applications that display a modeless dialog box using DLGMODELESS. DLGISDGMESSAGE determines whether the message is intended for one of the currently displayed modeless dialog boxes. If it is, it passes the message to the dialog box to be processed.
DLGISDLGMESSAGEWITHDLG specifies a particular dialog box to check. Use DLGISDLGMESSAGEWITHDLG when the message loop is in a main application and the currently active modeless dialog box was created by a DLL.
