C# and Scriptlet

[eddie]

Hi, my colleague wrote a scriptlet to get server wide environment variables
from ASP. However, my web application is written by C#, and I try to write a
program to access that COM but I always get a error. How can I solve this
problem? Any solution? Thanks!


An unhandled exception of type 'System.InvalidCastException' occurred in
mscorlib.dll
Additional information: QueryInterface for interface
ScriptletTypeLib.Automation failed.



ScriptletTypeLib.ASPEnvClass ASPEnv = new ScriptletTypeLib.ASPEnvClass();
Console.WriteLine(ASPEnv.GetItem().ToString());

Hi eddie
may be i didn't get your problem correctlly but , if the com component was
working fine then all what you have to do is .... Set the AspCompat
attribute of the Page directive "of your asp.net page"to true. and i hope
this solve the problem .....

Hi Mohamoss, thank you for your reply. In fact, I come from hp AsiaPacific
IT team, and now we manage several Web and DB servers. In order to manage
these staging and production servers well, my colleague wrote a scriptlet
for our ASP websites, so that our web developers can use the scriptlet to
query the Server Variables to know which server it is hosted and which DB to
use. However, some websites are written in C# by me, and I tried to call the
COM in global.asax but fails with the following error message. Can you give
me some hints about how to call this kind of COM (scriptlet) in my C#
program?

ScriptletTypeLib.ASPEnvClass ASPEnv = new ScriptletTypeLib.ASPEnvClass();
string ServerName = ASPEnv.Item("PROD_DB").ToString();





thanks,
