New to ADE 4.6

interface IAdeUICallbacks (ADE)

An application can implement this interface (as a COM interface) in order to intercept evaluations of the MsgBox function in expressions. This provides an opportunity for a program that uses ADE to display message boxes during evaluation in its interface.

To use this, your program must implement a COM class with each of the messages, such as the MsgBox method. As a COM class, it will implement the QueryInterface method from IUnknown, and its QueryInterface method must report that it implements this interface. You then instantiation an instance of the class and pass a pointer to that object to CAEngine::SetCallbackObject.

Methods

LONG MsgBox(string title, string text, long buttons)

Called when the MsgBox function is evaluated. You implement this method and can display a message box or other feedback to your end-user. The return value indicates what button was pressed to terminate the message box, as follows:

1 = OK
2 = Cancel
3 = Abort
4 = Retry
5 = Ignore
6 = Yes
7 = No

The «buttons» parameter has the following values:

0 = OK only
1 = OK and Cancel [Default]
2 = Abort, Retry and Ignore
3 = Yes, No and Cancel
4 = Yes and No
5 = Retry and Cancel

which are then added to one of these values:

0 = no icon
16 = Critical
32 = Question
48 = Exclamation
64 = Information
