Hello,

I am getting this error when I use the .Common dll   - where can I find the version that works witht he VisaNS .. it requires the 274 version whereas I have the 243. I've searched for the newer version in vain.

Thank

david

Did you create this example or are you just running an exe?
Make sure you are using the same version of VISA that the exe was created with. You might also consider creating an installer if you just need to run something on another machine

It's all set. I was not using the 4.0 version .. Thanks

Are there actual C# examples on how to use those drivers.  I am using a sample code and keep triggering an error 'null exception' when i try to read back my HP Meter string

string

HPAddress; object responseString = null;

HPAddress =

"GPIB0::22::INSTR";

mbSession = (

MessageBasedSession)ResourceManager.GetLocalManager().Open(HPAddress);

respondString = mbSession.Query(

"ID?");  <-- I get an error here saying it's timing out

I tried using NI-SPY to see what is going on but the code is in C I believe and it sees the correct model number !!

There are samples available under C:\Program Files\National Instruments\MeasurementStudioVS2005\DotNET\Examples\Visa

Isn't the query string supposed to be "*IDN?"  ?
