script to make chanel name a variable

[flat4flamer]

HI,

I'm pretty new to writing script but am totally stuck on this. 

I'm trying to write a spript to create a time channel based on sampe rate (the equation is simple) but the part where i get stuck is every time i load a different set of data my script is stiff refererencing "channel group2" so what i need is an input button/drop down box.....etc to sellect what channel group it should be using. 

Any ideas?

Hi Steve,

I am Ed from National Instruments Technical Support. I am happy to assist you with your request today. I'd just like to clarify, are you wanting to have this functionality in DiAdem rather than LabVIEW?

From what I can tell so far you could use a numeric control such as a dial, convert the numeric to string in your script and then concatenate this number to your channel name. You could also store your channel names as a string array and have a script acquire the string in the array at the given position, input from a numeric dial. Both methods can then be executed using a button. The input button is available under Visual -> Manual Instruments, which the numeric dial is also located in.

I hope that this is helpful and if you have any questions regarding your query please don't hesitate to ask.

Best Regards,

Ed

Hi Steve,

If you want to create a script that always adds a time channel for the most recently loaded data set, then you can use the "Active Group" in your script:

Set Group = Data.Root.ActiveChannelGroup
Set TimeChannel = Group.Channels.Add("Time", DataTypeChnFloat64, 1)
Call ChnLinGen(TimeChannel, 0, LastXvalue, XvalueCount, "s")
