How to upgrade VIs from 3.1 to 5.1.1

[Srinivas_Aluri]

I need to run Labview 3.1 program in Labview 5.1.1. The program is for controlling a Tektrobix-VXI VX4244, it uses an old 16bit dll. How do I change the LV program for a 32 bit dll.

What dll? If it's the one for VXI and the board is full VXI compliant (as the name states) it should work with LV drivers.

The old program (Labview3.1) uses a 16 bit dll(TKVX4244.dll- TektronixVX4244). But for NT there has to be a 32 bit dll for TektronixVX4244 namely TKVX4244_32.dll, which I already installed. Now, when I try to run the Labview3.1 program in Labview 5.1 on NT, its still looks for TKVX4244.dll instead the program should be changed to look for TKVX4244_32.dll, what do I do to change it?

I don't remember how LabVIEW 3.1 called a .dll. Was there a plug and play driver that was converted to a LabVIEW one? You should be able to get the rest of the driver (CVI fp, etc.) and update it that way. If the old program used a CIN to communicate with the .dll, then you might have to go into the old program and replace all of the old instrument calls.

Try to go down in subVIs to see where the old dll is accessed by LV (or if you can, send me your VIs and i'll take a look - costmiha@yahoo.com).
