dynamically allocated data socket item drops from the data socket server

[TerryMoss]

Hello,

I have a data acquisition program that writes it's data to a data socket for another program to re-dsiplay it.

Seems to work well enough, but after sometime, the data acquisition program seems to disconnnect that item from the server.

Initially, the item was being dynamically created, i.e. I just used the data socket binding and enable options in the graph control to attach it to the data socket server.

I have now added the data item manually so that both programs just attach it, but it will be sometime before I know if this helps or not.

Any othe rsuggestions are appreciated.

TerryMoss,

Have you compared your application with the DataSocket examples in LabWindows/CVI? Which DataSocket protocol are you using? DSTP, OPC, LOOKOUT, HTTP, FTP... When the item gets disconnected, are there any errors? If so, could you please post a screenshot of them.

[TerryMoss]

There aren't any error messages, the writer is just not connected.  I'll have to look into the protocol, it's been almost 10 years since I created the base code for this.

That being said, there is no real code behind it, the program automatically connects the graph to the data socker server.

Okay, so the application has worked correctly in the past? What has been added since then and would it be possible to get a screenshot of it?

[TerryMoss]

What changed was that I added the graph the the data socket.  I added the item manually and it seems better, but it takes days to really know.

I'll update the status early next week.

Thanks

Terry
