An exception of type 'unknown exception' was not handled

[khalsa]

I have a dll created in c++. I registered it using regsvr32. When i use the below code in visual basic it works fine and writes a file to the c drive. But when i run it with asp in Visual interdev i get the following erro and nothing is written to the c drive. It used to work before i did a reinstall of nt on my machine. What could be the problem.
An early response would be appreciated.

Error message :
