I have a problem with reading from the IO Warrior 24
When i use the example software (converted to vb.net 2003) after one read the software hangs.
Also after reading the datasheet and program it by myself:
Res = IowKitRead(iowHandles(0), 0, data(0), N)
The software will hang, is there somebody who have a working read IOW24 in vb.net?

The software does not hang, it waits for new data from the IO-Warrior which comes only if there is a change of status on the ports.

I don't know so much about VB. But its the sam way like "IowKitRead()".
you need the same parameter but if you use "IowKitReadNonBlocking()", you may do this with if.
The sample-code in the IOWKIT.DLL shows, how it works. And i dont think, thats so different with VB
