Problem launching Excel from server
Posted on 2001-09-03
Hi kind people - I wonder if you can help with the following...
I have written a simple DLL in VB6. The DLL opens Excel97, puts some values on a worksheet, runs the chart wizard and then saves the chart generated as a gif file. This gif file is then going to be displayed within a web page.
I am instantiating the DLL from some server side script in an ASP page, and this all works fine on my development server.
Unfortunately when moving the application to a test server, this functionality no longer works. When the users navigate to the web page with this ASP code on, they get the error message:
Method '~' of Object '~' Failed (800a03ec).
The DLL is called directly from the ASP page (i.e. not using MTS) and the asp apge runs under IIS.
I know that Excel is installed and working on the test server, and that my DLL is correctly installed / registered ( I can run a VB compiled EXE which calls the same DLL with no problems).
I have looked through MSDN and Technet with no luck so far. I thought that it could be permissions related - I have tried the following:
Created a user with access rights to log on locally to the server. Logged on as that user and checked could access Excel / the DLL. In IIS Admin, for the web page I am using, set the properties, then file security to allow anonymous access and to use the special user i created.
What is particularly annoying is that it worked fine in development, and I can't find any differences between the development server and the test server!!!
Anyone who can solve this will be worth their weight in gold!
thanks in advance for your help...
