Arg 1 error

[jsandra]

Hello everyone,

I have PCI- 7340 and I am using a custom software to control it. the driver used is Ni motion 18.0 and I don't see any VISA driver software installed, I don't understand why I am getting this error. I am very new to this software and controllers. Kindly reply. I am also getting Open TCP connection error also

Thanks,

Sandra

I doubt most can troubleshoot a VI from a picture of a front panel containing a truncated error message. You probably need to provide significantly more information.

Who wrote the "custom software"? What does it do? Can you attach the VI?

I guess the the TCP part is a completely unrelated problem and you don't provide any details at all.

Please fill in all the blanks so somebody can hopefully help you. Thanks!

I have solved it, thanks. I have a new error with file path. I am not sure about the error, I am literally a rookie interns of lab view knowledge. would you like to look at the error ?. I also want to contact you privately if its OK .

Since you still have errors, the problem is not solved. Right?

Error 7 is "file not found". Does a file named "C:/tape info.ini" exist? This must be a very old program. Newer OS version highly discourage or even prevent writing to the root folder (which is a very bad idea anyway!). Where does that file originate? Does it get installed or written by the application later? Obviously, it's not there, possibly due to permission issues. Try to see if running the program as administrator help. I assume you know how to do that.

Any reasonable program should properly deal with missing ini files and work around the situation. Just throwing an error at the user as we see here is bad form! Who wrote the program?

No, I don't do private consulting because nobody would be able to afford my rates. 😄

Hello Sir,

the tape info. ini file is a path constant. I have checked the block diagram and also used the debugging tool. looks like the file should be already present. so, it's not written after the execution. I was able to run most of the project. without this file a few buttons are inactive ( I guess it's a safety feature), the problem is, I am not sure what was in the file. it was an old program operated on the windows 7, our old hard disk was corrupted and unfortunately we didn't have a backup. By any chance can we write down a new file and define the path again ?.

Thanks and regards,

Sandra.
