Dialog Function: Sends a Windows message to a dialog box control.

Module

USE IFLOGM

result = DLGSENDCTRLMESSAGE (dlg,controlid,msg,wparam,lparam)

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.
controlid	(Input) Integer. Specifies the identifier of the control within the dialog box. Can be either the symbolic name for the control or the identifier number, both listed in the Include file (with extension .FD).
msg	(Input) Integer. Derived type `T_MSG`. Specifies the message to be sent.
wparam	(Input) Integer. Specifies additional message specific information.
lparam	(Input) Integer. Specifies additional message specific information.

Results

The result type is INTEGER(4). The value specifies the result of the message processing and depends upon the message sent.

The dialog box must be currently active by a call to DLGMODAL or DLGMODELESS. This function does not return until the message has been processed by the control.
