I need to use a inhouse designed and made instrument in a LabView platform but the driver was written in VB 6.0 so I build a dll using VB to allow LabView to communicate with the instrument. I succeeded but the problem is whenever I exit my test application and load it back in I got an error that say a dll file is not found. This dll file is called by the dll I built and it was written in C language. I had to set the automation refnum again just to get rid of this error. Any help is appreciated.
I thought perhaps the OS registration had some problem so I even wrote a wrapper in VB .Net to make use of its type library registration to run my application but the same problem occurred.
Go to www.sysinternals.com and download a tool called Filemon. When you run this, set the filter to the name of your EXE (you're VB.NET test app would be best - generates less entries than LV will) and then launch the program. Filemon shows all the file I/O access (including loading DLLs) - so you might see what command is failing.
