AskMsgText(question, title, maxText, default, password)
- AskMsgText(question: Text; title: optional text; maxText: optional positive; default: optional text; password: optional boolean)
Shows a message box with specified «title», «question» and a textbox containing the «default» text, if any, and allowing up to «maxText» characters (or up to the number of characters in default, if that is greater). It returns the text entered by the user into the text box, or the default if none.
The message box appears only when this function is evaluated. Since Analytica caches results once they are computed, if you embed this in a variable, you will not see the question every time you view the result. To trigger the question again, you must change something upstream that the variable depends on, so the result is invalidated. If you place it inside a button script, you would see it every time the button is pressed.
When «password» is true, obscures the characters typed, showing asterisks rather than the typed characters.
The box displays OK and Cancel buttons. Pressing Cancel causes the current computation to abort.

When evaluated in the Analytica Decision Engine (ADE), it calls IAdeUICallbacks::AskMsgText(...). From within that callback, the parent application can display a dialog, collect input from the end-user, and return that as the return value. To receive the callback, the parent application must have previously registered the callback with ADE using CAEngine::SetCallbackObject( ). If it has not registered a callback, then «default» is returned.
