daq assistant cannot be edited

[DBadowski]

When I try to edit the settings of the DAQ Assistant it gives the error "Remote editing is not supported".

This happened after I coppied it into another vi to experiment with the settings without making changes

to my main program. What can I do to allow editing again?

What is your version?

[DBadowski]

I'm running v8.0

[DBadowski]

I figured it out. When I opened the vi from my project window it gave that error when trying to edit the DAQ Assistant but it worked when I opened the vi by itself.  Why is this?

[Mr.F]

I’m a bit confused to the series of events here. You copied a DAQ Assistant from you VI to a new VI and got that error message? And this error message only occurs when you copy the DAQ Assistant from the VI you opened from the project window, but not when you copy the DAQ assistant from the VI open separately? I tried both of these but was unable to reproduce your experience. Unfortunately I don’t have LabVIEW 8.0 installed on my machine as we technically no longer support this version. It’s possible there is a bug in the way the project interacted with your VI that is not there when you open the VI separately, but I was unable to find any past information on that.  Do you have another version of LabVIEW to test with?

[DBadowski]

Sorry for the confusion. I had copied a section of code with the DAQ Assistant to a new vi to fiddle with without messing up the original program. When I was done that copy was deleted. After that I was unable to open the DAQ Assistant properties in the original vi so I associated that with the copying I did. It turns out that was a coincidence. If I open the .vi directly by double clicking the file I can open the DAQ Assistanrt properties, but if I open the vi from the Project Explorer window I would get the error. Can you tell me why the Project Explorer interferes in this way?

[Mr.F]

OK, thanks, that’s clearer. Does this happen when you try and edit the VI or only when you try to edit the DAQ Assistant? Does any other express VIs have the same behavior?

[DBadowski]

My vi is always editable no matter where I open it from, the error only happens with the DAQ Assitant. I tried another ExpressVI, Simulate Signal, and it was editable whether I opened my vi file directly or through the project explorer. I also tried to see if when I added the ExpressVI (file opened directly or through Project Explorer) made a difference. In either instance I was able to place the Simulate signal. However, I was not able to place the DAQ Assistant when my VI was opened through the Project Explorer. When I try adding a DAQ Assistant after opening my vi from project explorer the icon appears but the configuration wizard does not show up. Double clicking on the VI makes the cursor go to hourglass for a split second. Other than that nothing happens. It seems the problem is isolated to the DAQ Assistant, and only when the containing VI is opened from the Project Explorer.

I converted the DAQ Assistant to code. The resulting code is surprisingly simple and it's easy to make changes, add channels, etc. so I will use that instead of keeping it an ExpressVI. Though I have abandoned the DAQ Assistant I am still interested in finding out what's causing this error in case it starts happening with other VIs.

[Mr.F]

Well I’m glad you’re not having trouble with the other express Vis or editing your VI in general. What version of DAQmx are you using? Do you have another version of LabVIEW?

[DBadowski]

I have LabVIEW 8.0, this is our only version. And I'm using DAQmx 8.7.
