Error in the call of a DLL function

[remyste88]

Hello,

I'm trying to control a Switch Matrix of Agilent (HP5250A) with LabView 6.1. The connections are realized with GPIB. In fact, I have some problems with the DLL called "hpe5250a_32.dll". If I try to start my VI, this error occurs:

"An exception occurred within the external code called by a Call Library Node. This may have corrupted LabVIEW's memory. You should save any work to a new location and restart LabVIEW. VI "hpe5250a Open List - modified.vi" was stopped at Call Library Function Node 0x844 of subVI "hpe5250a Open List - modified.vi" "

Must I install the DLL in a special location as C:\VXIpnp\WinNT\Bin? I have nothing about HP5250 instrument
here... and it is maybe the problem.

Thank you very much for your help.

Le problème a été résolu par mail directement.

Il était dû au fait que l'utilisateur n'avait pas l'habitude des "instrument handle" dans labview et voulait utiliser certaines fonctions directement sans passer par les étapes de configurations.
