You receive a "Visual Studio must be used to add business logic to this form template" error message when you close the Form Options dialog box in InfoPath

When you close the Form Options dialog box in Microsoft Office InfoPath 2007 or in Microsoft Office InfoPath 2003, you receive the following error message:Note If you make changes before you close the Form Options dialog box, the changes are successfully saved even though you receive this error message.

This problem occurs when you create an InfoPath Form Template project in Microsoft Visual Studio 2005 or in Microsoft Visual Studio .NET 2003 and you click to select the Save using custom code check box in the Forms Options dialog box. When you select this check box, Visual Studio 2005 or Visual Studio .NET 2003 adds the OnSaveRequest event handler code to the project. Therefore, when you open the form template file (.xsn) outside Visual Studio 2005 or Visual Studio .NET 2003 in InfoPath, you receive the error message.

To work around this problem, make design changes to the form template file (.xsn) only when you work in the InfoPath Form Template project in Visual Studio 2005 or Visual Studio .NET 2003.
