Hi


I am trying to automate visio 2003 from a web application.I am using the Visio Interop to talk to the Visio application from my C#.NET code.
The code is as follows

===============================================

using Visio=Microsoft.Office.Interop.Visio;

Visio.ApplicationClass A = new Microsoft.Office.Interop.Visio.ApplicationClass();

Visio.Document AddedDocument;
Visio.Documents visioDocuments;
Visio.Page AddedPage;
Microsoft.Office.Interop.Visio.Document stencil;
Microsoft.Office.Interop.Visio.Master masterInStencil;
Microsoft.Office.Interop.Visio.Shape StartShape;
Microsoft.Office.Interop.Visio.Shape EndShape;

AddedDocument =A.Documents.Add("C:\\Program Files\\Microsoft Office\\Visio11\\1033\\SITPLN_M.VST");

visioDocuments= A.Documents;
AddedPage=A.ActivePage;
stencil = visioDocuments["ANNOT_M.VSS"];

masterInStencil =stencil.Masters.get_ItemU("Ceiling");



// This is just the connection part...Pasted it for continuity...The above code is the important one

double pinXInternal=820.676;
double pinYInternal=799.900;

StartShape=AddedPage.Drop(masterInStencil,pinXInte rnal,pinYInternal);
StartShape.Text="Start Shape";
EndShape= AddedPage.Drop(masterInStencil, pinXInternal - 300 , pinYInternal );

EndShape.Text="End shape";

DynamicConnector D= new DynamicConnector();
D.ConnectWithDynamicGlueAndConnector(StartShape,En dShape);

AddedPage.DrawRectangle(800,800,1000,1000).Text="R ectangle";

AddedDocument.SaveAs("C:\\Deepak\\NewWindowsDoc.vs d");

A.Quit();


===============================================
(I plan to initialize the Application class in Global.asax in the future)

The problem is this..This code works fine when i run it from a Windows app( the diagram gets created and saved )..however it chokes when i run it from a web app.I get a RUN TIME error which says

Server execution failed


I am using impersonation.I have also added all the identities that ASPNET could take (as far as I know) MACHINENAME/ASPNET,MACHINENAME?IUSR_MACHINENAME,NETWORK,NETWOR K USER( They din work I got Access Denied Error...and finally when nothing worked...i impersonated!!
It worked) BUt now..i get this new run time error.


The error shows up on the line that I initialize my Application class object

Visio.ApplicationClass A = new Microsoft.Office.Interop.Visio.ApplicationClass();

Like I said...the same code runs perfectly when I run it from a windows application.
PLEASE HELP ME.I can see I need to do some configuration settings.Not sure what I need to do.I searched around in many forums...but could not find anything on this.Any help would be highly appreciated.

Thanks
