LabWindows/CVI
LabWindows/CVI works with the DAQ Assistant in MAX to generate
code for a task. You can then use the appropriate function call to modify
the task. To create a configurable channel or task in LabWindows/CVI,
complete the following steps:

complete the following steps:
1.
Launch LabWindows/CVI.
2.
Open a new or existing project.

5.
Configure the NI-DAQmx task following the instructions in the
section.
6.
The DAQ Assistant creates the code for the task based on the
parameters you define in MAX and the device defaults. To change
a property of the channel programmatically, use the
parameters you define in MAX and the device defaults. To change
a property of the channel programmatically, use the
DAQmxSetChanAttribute
function.
Note
Refer to the NI LabWindows/CVI Help for more information on creating NI-DAQmx
tasks in LabWindows/CVI and NI-DAQmx property information.
Measurement Studio (Visual Basic, .NET, and C#)
When creating a task in Visual Basic .NET and C#, follow the general
programming flow in Figure 5-1. You can then use the appropriate function
calls to modify the task. This example creates a new task and configures an
NI-DAQmx channel on the SCXI-112511251125. You can use the same
functions for Visual Basic .NET and C#.

Programmable NI-DAQmx Properties
All of the different ADEs that configure the SCXI-1125 access an
underlying set of NI-DAQmx properties. Table 5-5 provides a list of some
of the properties that configure the SCXI-1125. You can use this list to
determine what kind of properties you need to set to configure the device
for your application. For a complete list of NI-DAQmx properties, refer to
your ADE help file.
