When you call a procedure defined outside your project, the Visual Basic compiler does not have access to the information it must have in order to call the procedure correctly. This information includes where the procedure is located, how it is identified, its calling sequence and return type, and the string character set it uses. The Declare Statement creates a reference to an external procedure and supplies this necessary information.
