VISA Example in Visual Basic .NET
To compile and run this example in Microsoft Visual Studio 2008:
1 Open Visual Studio.
2 Create a new Visual Basic, Windows, Console Application project.
3 Cut- and- paste the code that follows into the Visual Basic .NET source
file.
4 Edit the program to use the VISA address of your oscilloscope.
5 Add Agilent's VISA header file to your project:
a Right- click the project you wish to modify (not the solution) in the
Solution Explorer window of the Microsoft Visual Studio
environment.
b Choose Add and then choose Add Existing Item...
c Navigate to the header file, visa32.vb (installed with Agilent IO
Libraries Suite and found in the Program Files\IVI Foundation\VISA\
WinNT\include directory), select it, but do not click the Open
button.
d Click the down arrow to the right of the Add button, and choose Add
as Link.
You should now see the file underneath your project in the Solution
Explorer. It will have a little arrow icon in its lower left corner,
indicating that it is a link.
e Right- click the project again and choose Properties; then, select
"InfiniiVision.VisaInstrumentApp" as the Startup object.
6 Build and run the program.
