On the statement "Set gApp = New Word.Application" I get the following:
===========================================================================
Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
===========================================================================
Right clicking on Winword.exe and going to the security tab, I've given full rights to Anonymous, Guest, <system>\\Aspnet and Internet Guest Account. I don't have a 'IUSR_MACHINENAME' logon available, even when going to Add User -> Advanced -> Find Now.
I have no way of knowing exactly what 'user' the program is using in its attempt to fire up Word, so I can't create the user locally to make the program happy. Nor does the VB.Net code allow me to specify a user in the Word object creation statement.
