Currently I have excel .xla addin with a macro that was created by the Microsoft Office 2003 Web Services Toolkit. Works fine with XP and Excel 2003. Now some users in office have Windows 7 and Excel 2003 and I have to remove the references to the mssoap30.dll and msxml6.dll in order to have the .xla addin load correctly. At this time these Windows 7 users do not use this functionality. I believe the reason is they are missing the two dll's mentioned.
Question: What will I use when we move to a newer version of Excel on Windows 7? All the information I can find says that web services do not work in the newer versions of Excel or windows 7. It was mentioned to use managed code. Not sure what they are referring to. Any suggestions will be appreciated.
