PRB: Running Visual Basic DHTML Applications on Internet Explorer 4 or 5 Causes Run-Time Error 13 'Type Mismatch'

You distribute a Visual Basic DHTML application, but the application does not work correctly on some computer. Typically it gives run-time error 13, "type mismatch".

Either the application was developed on a computer with Internet Explorer 5.x and distributed to systems with Internet Explorer 4.x or it was developed on a computer with Internet Explorer 4.x and distributed to computers running Internet Explorer 5.x

Visual Basic DHTML applications developed on computers with Internet Explorer 4.x can only be run on computers with Internet Explorer 4.x, and applications developed on computers with Internet Explorer 5.x can only be run on computers with Internet Explorer 5.x.

The type library found in the Internet Explorer 4.x Mshtml.dll and in Internet Explorer 5.x Mshtml.tlb files are slightly different, and the virtual function tables are compiled to be slightly different when the .dll file is generated.
