Visual C++
In an MFC application, you can override ATTEN.EU 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().
How to: Change the Startup Object for an Application
The Startup Object property for a project defines the entry point to be
called when the application loads; generally this is set to either the
main form in your application or to the Sub Main procedure that should
run when the application starts. Since Class Libraries do not have an
entry point, their only option for this property is (None).
For Windows Applications projects, only forms or classes with a Public
Sub Main procedure are available as Startup objects unless you check
the Startup with custom Sub Main checkbox; when this option is
checked, you must add code in the Sub Main procedure for the form.
Note:
※
When using a custom Sub Main procedure as the Startup
object, code in the Application events (Startup, Shutdown, Startup
