How to add GetValueByPointer XNode in LabVIEW Application

[iErd]

Hi,

How can I add "getvaluebypointer.xnode" file that I use in labview and subvi to .lvproject (labview project file)?
In LabVIEW, how can I specify this in a support directory, also called a resource?

An XNode is purely an editor related function.  It uses scripting to help do things in the IDE and doesn't have any real use in a built application.  When you interact with an XNode in the IDE it generates code.  That generated code is brought into the application because it is needed.  But the XNode itself serves no purpose, and can't be used in the runtime environment, since it doesn't include scripting.

That being said why are you trying to do this?

Hi,

The subvi I'm currently working with has GetValueByPointer.xnode. It's a subvi that works fine, but I need to make it an app, but I'm getting an error in that part of the project file. I need to fix this urgently. Do you have a solution to help?

You aren't giving enough details.  What error?  Does the error remain if you replace the XNode with the equivalent G Code?  Again the XNode isn't doing anything that you can't do yourself, it just makes using the IDE easier.

That Xnode isn't from NI.

If you send me the VI that contains the XNode, I can replace the instance of that XNode with the code that's hiding inside it.

Hİ,

I followed the error code below and the solution steps given by the NI regarding this error,

Error 7 occurred at Call Library Function Node

Possible reason(s):
LabVIEW: (Hex 0x7) File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.

Now, this error does not come out, but when reading data from the array, a '0' value is constantly displayed.

now i sent subvi, what could be the reason for the error on it?

That XNode is from NI and is a function in vi.lib. It makes use of a shared library (DLL) file and the LabVIEW application builder seems to fail to detect this dependency automatically. You need to add that DLL explicitly in the build specs to be added to the exe build.

I don’t have a PC available to check but there have been discussions about this on LavaG and while I prefer to replace the Xnode through my own Call Library Nodes, adding that shared library to the build spec is much quicker and easier.

I believe the shared library resides in the resource directory inside the LabVIEW directory but don’t remember its name.

Try replacing it with this.
