Hi

I have created an asp.net project that exports items from datagridview to and outlook calendar
This is the code that i have used..

Dim body As String
        Dim ends As String
        Dim location As String
        Dim start As String
        Dim subject As String
 
        'Create an outlook application
        Dim oApp As Microsoft.Office.Interop.Outlook.Application
        oApp = New Microsoft.Office.Interop.Outlook.Application()
 
        'Get Namespace and Logon
        Dim oNS As Microsoft.Office.Interop.Outlook.NameSpace = oApp.GetNamespace("mapi")
 
 
        'Create a new appointment
 
        Dim oAppt As Microsoft.Office.Interop.Outlook.AppointmentItem
 
 
 
        For Each row As GridViewRow In GridView3.Rows
            oNS.Logon("YourValidProfile", Missing.Value, False, True) 'todo:
            oAppt = oApp.CreateItem(OlItemType.olAppointmentItem)
            body = row.Cells(0).Text
            ends = row.Cells(1).Text
            location = row.Cells(2).Text
            start = row.Cells(3).Text
            subject = row.Cells(4).Text
 
            oAppt.Subject = subject
            oAppt.Body = body
            oAppt.Location = location
 
            oAppt.Start = start
            oAppt.End = ends
 
            oAppt.Save()
 
 
            oNS.Logoff()
        Next

It works locally on my machine but once i have uploaded the files to the server on which the application is running then i get the following error.

Could not load file or assembly 'Microsoft.Offi ce.Interop.Outl ook, Version=12.0.0. 0, Culture=neutral , PublicKeyToken= 71e9bce111e9429 c' or one of its dependencies. The system cannot find the file specified.

I have loaded the PIA's on the server itself and have checked the C:\Windows\Asse mbly folder and the Microsoft.Offic e.Interop.Outlo ok assembly is within that folder and the version is 12.0.0.0

Can anyone direct to a solution if possible please.

You need to install Outlook on the server... the Interop class (in your project) is just a wrapper class that allows .NET to access the COM objects in the Outlook assembly. If this assembly (Outlook) is not installed on the server then this will not work.

I have installed Outlook on the server. Now i get this response

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005.

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}\ASPNE T 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="tr ue"/>, the identity will be the anonymous user (typically IUSR_MACHINENAM E) or the authenticated request user.

To grant ASP.NET 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

Have you tried to do what the error message is suggesting that you try to do?
