Now change the slider’s values from 1 to 2. This tool is used at runtime to operate the controls in the Front Panel. This tool allows you to change some of the object’s properties. In the Tools toolbox, click on the Operate Value tool. The horizontal slide will be used to select the channel to “watch” (i.e., the channel from which data will be read and displayed onscreen). In the Front Panel, insert a Horizontal Slide from the Controls toolbox. This will make the WinDaq control available to all frames within the sequence. Connect the WinDaq Control to the Sequence. 
These paths tell LabVIEW to take information from one object and send it to another object. The wiring tool can be used to create “paths” that are to be followed during the execution of the program.
Click the Wiring tool in the Tools toolbox. This will make it easier to identify what the object/picture represents. In the Diagram window, right-click the newly created control, select Show then Label to display what it is. This will give you a list of all currently available ActiveX controls on the system. Scroll to find WinDaq Control select it, and click OK. Right-click the container and select Insert ActiveX Object…. This section can be found by searching for “ActiveX, introduction” in the index. Refer to the “Introduction to ActiveX” secondary topic in the LabVIEW online help documentation for a description of how LabVIEW works with ActiveX controls. ActiveX controls work on the basis of server-client relationships. The ActiveX container is necessary to insert an ActiveX control into LabVIEW. The Front Panel is what will become the User Interface. Insert an ActiveX Container into the Front Panel. This is the “behind-the-scenes” work that runs the Front Panel. The diagram drawn in this window will determine what gets executed, in what order, etc. #Labview data acquisition code#
The Diagram window is the source code of the project.
Insert the selected sequence structure into the Diagram window:. In this example, the sequence structure will be used to “start” the WinDaq control before it is used. The sequence structure forces the diagrams to execute in a particular order and separate the diagram into logical execution blocks. Open a new LabVIEW project (this is usually the default when LabVIEW starts up). #Labview data acquisition archive#

This procedure uses the WinDaq control which allows data acquired by WINDAQ® Acquisition software to be simultaneously made available to LabVIEW.
This application note describes a step-by-step procedure you can use to access any DATAQ Instruments ActiveX control from LabVIEW. DATAQ Instruments hardware products may be programmed under LabVIEW by applying our ActiveX software tools. LabVIEW is a popular programming environment for many data acquisition applications.
