The Problem

After finally making the jump from Visual Studio 2008 to Visual Studio 2010, a project using Infragistics NetAdvantage 2008.3 started throwing the “Code generation for property ‘Image’ failed” error in Visual Studio 2010.

The NetAdvantage incompatibility with Visual Studio 2010 appears to be related to Windows Forms and making any changes to the image of the form.

The Fix

Infragistics has reported an error in some versions of it’s product with Visual Studio 2010.  It appears that NetAdvantage 2008 is not fully compatible and no patch has been provided.  Luckily I still had an upgrade for NetAdvantage 2009.1, of which after being patched / updated to the latest build works.  The standard install of Infragistics 2009.1 or 2009.2 does not work and must be patched / updated.  Check with Infragistics or download the patch directly from them from your downloads area.

Compatibility

NetAdvantage WinForms compatibility with Visual Studio 2010

• NetAdvantage 2008.x and previous versions – Not fully compatible, see error above
• NetAdvantage 2009.1 Unpatched  - Not fully compatible, see error above
• NetAdvantage 2009.1 Patched to 9.1 2094  – Compatible, fixes above error
• NetAdvantage 2009.2 Unpatched - Not fully compatible, see error above
• NetAdvantage 2009.2 Patched to 9.2 2083 - Compatible, fixes above error

Original credit for solving this goes back to an Infragistics employee in their forums:

I’ve tested their solution with my project and reflected the results above.  As always, back up your solution before making changes!

Scenario

On machines where Vista/W7 is installed there appears to be an issue when checking to see if a user is in a role.  User Account Control (UAC) must be on to reproduce the issue.  The result is that the value returned is always FALSE even when the user does belong to the group.

Sample Code (UAC must be on to produce error)

If My.User.IsInRole(“My Domain\My Group”) Then

     Return True

Else

     Return False

End If

Workaround

To get around this I created a function using other .Net functions.

Public Function IsInUserRole(ByVal RoleToFind As String) As Boolean

    Dim id As WindowsIdentity = WindowsIdentity.GetCurrent
    Dim irc As IdentityReferenceCollection

    ‘ Gets a SID list of groups the user belongs to

    irc = id.Groups

    For Each ir As IdentityReference In irc

        ‘ Need to convert the SID to plain english

        Dim act As NTAccount = CType(ir.Translate(Type.GetType("System.Security.Principal.NTAccount")), NTAccount)

        If act.Value = RoleToFind Then

            Return True

        End If

    Next

    Return False

End Function
