About Application Programs - Picotest M3500A User Manual

If you select the RS-232 interface and then set the HP-IB address to the
talk only address (31), the multimeter will send readings over the
RS-232 interface when in the local mode.
D. About Application Programs
This section provides a brief description for each M3500A sample
collection.
Visual Basic
Learn how to create and use PICOTEST IOUtils components, controls,
data access, and more with the Visual Basic sample applications. For an
overview and installation details, see Visual Basic: Explore the Samples.
Visual C++
In an MFC application, you can override PICOTEST IOUtils interfaces in a
class as well as provide additional interfaces. The example in this article
illustrates how to override an interface in a class while preserving the
original interface implementation so that it can be delegated to by the
new interface implementation. Browse the Visual C++ samples code;
see Visual C++ DEVQUERY Sample Application.
Using MEASure? for a Single Measurement
The following example uses the MEASure? command to make a single
DCV measurement. This is the easiest way to program the multimeter for
measurements. However, MEASure? does not offer much flexibility. The
example is shown in Visual Basic.
Creating the Application
Create a new Visual Basic project as follows:
1. Create a new Standar.EXE project.
2. To set the startup object for a Windows Application to Sub Main
3. Add New Module, and declare a Sub Main().
