SUMMARY
IntelliSense, or Automatic Statement Completion, is the ability of an editor to complete design time function declarations, object references and other editing functions. This ability, which is integrated into other Visual Studio components, is not natively available in Visual FoxPro.



MORE INFORMATION
In order for IntelliSense to work, the editor needs to know explicitly, at design time, the referenced object type. Since Visual FoxPro is a weakly typed language, this information is not available during design time and is not available until run-time, with some exceptions. In order for the editor to know what object to examine for the appropriate methods and properties, a type declaration similar to the following is needed: PUBLIC oForm LOCAL oADO, oRef With the following statements, Visual FoxPro cannot resolve the references until run-time. The class for "myForm" actually depends upon the SET CLASSLIB setting at run-time. Similarly, oForm and oADO could potentially change on subsequent executions of that line of code. You cannot be sure what the references are until the code actually executes. Here is an example: oForm = CREATEOBJECT('myForm') && Visual FoxPro Class oADO = oForm.myRecordSet      && Component Object Model (COM) Class oRef = oADO                   && Unknown object reference In Visual FoxPro, without a strongly typed language, we cannot know at design time that "oForm" is derived from the "myForm" class. In other Visual Studio languages, such as Visual C++, Visual Basic, and Visual J++, the strong language typing gives the editor and compiler system the ability to make use of IntelliSense.

As an alternative to having native IntelliSense, there is a public domain utility called SuperClass available for download from the following World Wide Web URL:

This utility makes IntelliSense functionality available within Visual FoxPro. On the toolbar, click Tools and then locate the SuperClass utility.
