When working on developing or debugging an app that is created via automation (i.e. ActiveX DLL), keep in mind the following: if you invoke that app from a calling program

When passing a variant array by reference, make sure to use Dim to declare the statement before using Redim. Example: Private Sub Command1_Click()Dim x as integer ReDim v(2) As Variant

When you have multiple web pages calling the same client script code, locate the shared script code in a separate file (e.g. Shared1.js) and reference the shared code in each
