System_Exec (Inputs and Outputs problem)

[juanfer23]

Hello,

I am trying to create a simple executable, and in it, i need to change the inputs parameters and read the output.

I created my executable checking the Pass all command line arguments to application box. (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000YHdICAW&l=en-US)

Then, I create another subvi for writing and reading the parameters (see call.vi attached).

In Command Line i write the path of my executable "c:\Desktop\Call\Test\Test.exe" and then I write -- "c:/newpath" "d:/path2" (these are my two inputs parameters).

I run the program and my executable is open, but I cannt see these input parameters changed (I closed it), but I also dont get any output.

Could you please help me with these??

Hello!

To read the argument you have to read it using Property Node as shown on the webpage you have linked.

As far as I know Exe built from VIs doesn't have standard output. I can suggest the workaround - write the output to the file and read in a calling VI.

I have also attached the simple VI Snippet (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x2PkCAI&l=en-US) of my VI which built to exe reads arguments properly.
