NIPALK

Hi,
I am having a very similar problem as I found that somebody else had on the discussion forum. But, no one answered, so I am posting my own question, in hopes that somebody who knows about this stuff will help. I am also using Labview6i, Windows 98, and a variety of hardware. We have a PCI-MIO-16E-1, DIO, GPIB, and a few serial port devices.
I added a new version of code onto the test station, basically made a few non-hardware related changes, and all of a sudden my new code doesn't work. Although the old code does. But the two versions are almost the same. I even tried it on a different computer using the same set how hardware and OS, but I am still getting a blue screen and an error message.
The message I get looks like this:"An exception 00 has
occured at 0028:C29A440 in VxD NIPALK(01)+ 00000360. This was called from 0028:C29C7740 in VxD NIPALK+00023660. It may be possible to continue normally". It happens right after a reboot of the PC. Sometimes it goes away after the first run, but most of the time it doesn't. I've also noticed that it start to hick up at places that Aquire Data, specifically the tests that use AI Aquire Waveform.
Any help or suggestions would be greatly appreciated.

Thanks,
Julia

It's hard to tell exactly what causes the problem. Since it happens at places that Acquire Data, one general idea would be that something wrong is with the read buffer. If this is a string buffer which is shorter than your reading data of waveform it could corrupt system memory and crash the system. Good news that you still have working version. To find the wrong place I would try one change in a time and see when it fails.

EURIKA! I solved the problem! It turned out that I had to upgrade NIDAQ, and it started working again. It works without errors so far, so I hope it will stay this way.
