Great! The purpose of my work is to automate the drawing of my telecommunication network. In my disposal: a datase sotirng my network desciption. The idea is to read from this database and draw the network map insigth a visio sheet. Next, i will be working on how to dynamically update the map I hope it's clear! Thanks

So the only way is to develop an application which runs on the server side so that everyone having Microsoft application virtualization client can access and run its? If i'm right how to built such an application? Thank!

First of all, thank your for your contribution! In fact, i have Microsoft application virtualization app-v client installed locally on computer trough which Visio is streamed. So i can open and read manually visio as it was locally installed locally on my machine. Now, other than running the code on the server side, is there anyway using my c# code to instantiate the viio application. I think it's possible!! Thanks

Hello! I have visio running on my computer trough Microsoft Virtualization software which streams visio from a remote server. I'm writing a c# program to command visio using the reference Microsoft.Office.Interop.Vsio, when trying to instantiate the visio application "Application app=new Application()" an exception is raised and roughfully telling that Visio is not installed. Does someone, know how to address this issue? Any contributions will be really appreciated!

I installed a visio trial version and everything works perfectly! :) Thus i will need to locally install visio on each sytem of my network instead on having its installed on a server and using client app to acess its in order to run my soft. This is the issue actually. Anyway, thanks for your valuable contribution.

Ok, since it's still a Microsoft technology (i mean the virtualization application for software ), is there any way to access Visio without having to install its on my real system? The fact is that the application Virtualization is an application streaming solution and i run visio manually without any issue. Thanks for your interest and constribution :)

Thanks for your reply. I have visio installed on my system trough Microsoft Virtualization application. That is why, the COM for visio is not found comparing to the COM for Word or Excel which i directly installed on my system(locally installed). How to access visio objet which is installed on a virtual server as it is my case from my c# program. Any idea! Thanks

i'm using the reference Microsoft.Office.Interop.Visio to create a visio drawing document. When trying to obtain a visio application in my c# program as follow : "Application application =new Application()", i got the error below:

La récupération de la fabrique de classes COM pour le composant avec le CLSID {00021A20-0000-0000-C000-000000000046} a échoué en raison de l'erreur suivante : 80040154 Classe non enregistrée (Exception de HRESULT : 0x80040154 (REGDB_E_CLASSNOTREG)).

When using the same type of reference such as "Microsoft.Office.Interop.Word" or "Microsoft.Office.Interop.Excel" everything works properly. Any suggestion on how to address this issue will be really appreciated. Thanks!!
