How to Run a .msi file in a LabVIEW Application Installation
There is no support of the running of .msi files in the options in the installation of a LabVIEW application. But we can file other ways to do it. Because installation only support *.exe or *.bat file to run after in LabVIEW application’s installation, so we can work around it with one of following methods: [...]
How to Add Version Control in LabVIEW
LabVIEW does not have built-in version control, but we can use 3rd party software to realize version control in LabVIEW. First, use menu Tools>>Source Control>>Configure Source Control to config the 3rd party source control software to integrate into LabVIEW, as in the following picture:
A Better Way to Access Variables in Complex Programs in LabVIEW
In some LabVIEW programs, we need to access the value of a variable which is inside a loop from outside before the loop is over. Most of us will use a local variable of a indicator to do this job. But this is not a good way to do this job. For example, if you [...]
A Note about DAQ Assistant and 200279 Error in LabVIEW
Just a few days ago, I created a simple LabVIEW program which read about 32 channels at 2KHz and display the data and write the data into file. The program is quite simple, so I used DAQ Assistant and Measurement File Express VI to read and write the data in one loop as the following [...]
Change Windows XP Environmental Variables in LabVIEW
The Windows XP’s environmental variables can be changed in Windows’ control panel. And if you want to change these variables in LabVIEW, you can use the System Exec function and the command “path=dir1; dir2; dir3” together to realize it. Using “cmd/c path=dir1;dir2;dir3” as the input parameter to System Exec function in your LabVIEW program will [...]
Make Artificial Data Dependency in LabVIEW
Sometime, we need the data flow in LabVIEW not to be naturally. In this case we can use sequences structure or artificial data dependency to realize it. But, usually a single frame sequence with an error wire or other data wire is sufficient. A multiple case sequence structure is not needed. If you use artificial [...]
