Hi,
I am currently converting an application that automated PC-DMIS in VB6 over to C#. Our application does the following:
1) Ask the user what PC-DMIS program (i.e. a PRG file) they want to run
2) Launch PC-DMIS passing in the name of the program file selected
3) Get PC-DMIS to run a series of measurements on a Scirocco machine
4) Import the measurements from PC-DMIS into the application for processing
5) Process the results (basically we compare the measurements to a baseline, then insert the deviation into a database)
What I observed is that for any program (we've tried quite a few and this seems to be consistently happening), the VB6 application takes approximately 30 seconds to perform step 4, whereas the C# application takes around 2.5 minutes.
Can anyone help with the following questions please?
1) We directly ported the code from the legacy VB6 application to C# so the new program isn't doing anything different from what the old VB6 one used to do, so why does C# take so much longer than VB6 to perform the import?
2) Is there any way to speed it up, e.g. I think I read something on a forum that VB.NET may be faster, but I can't find anything technical from Microsoft to support that so I can't really justify burning a lot of hours to convert from C# to VB.NET in case it is the same speed?
Thanks!
