killing a dll process

I'm using another company's proprietary dll in a program and they can't help me.

Sometimes, when I 'close' the connection to it, the process doesn't die.

Does anyone know how I can track the process in Windows so that I can kill the PID if necessary?

One important note: there may be more than one instance running from other programs, so I can't just search the process list and kill the first one I find!

I need to kill only the one I spawned.

Also, when I 'open' the dll, it does not return any kind of ID.

Any clues?

Thanks.

can you paste the line of code that creates the process?

If you create an instance of it , when using it.

All you can do is setting this object to nothing.

If there are still processes running after setting your object to nothing then they have made a bad dll.

Public Declare Function mqlOpen Lib ".\mqlvb32.dll" () As Integer

result = mqlOpen()

Returns an integer
0=fail
1=success

hmmm, i would write to the designers meself :(
