Get a group's index by knowing its name

[Simon_Aldworth]

I notice that there have been a number of changes to function behaviour such that referencing groups by their names has become increasingly difficult.

I have data files that may include a group whose name I know but not its index. ChnAlloc used to allow you to place a channel in a particular group without having to know the index of that group. Thus I could easily place new channels into my group whose name I knew but whose index I didn't. Now I can't do that.

Instead I need a way of determing the index of a group by its name. This should be easy and I can't for the life of me understand why there are so many ways of obtaining information about channels but not groups. Surely it would make sense to have a variable called GroupNo("Group Name")?? I considered using GroupPropValGet and asking for the group's index number but I can't because this function requires you to use the index number to specify the group in question.

Will I have to go to the lengths of writing a loop that passes through each group name and checks whether it matches the name I'm after??

Cheers,

Si.

Simon,

can you please provide some additional information:

- What version of DIAdem do you use?

- What did make working with groups moe complicated than it was before ? Can you please provde an example ?

Hey Simon,

I use this in my code to get the group reference number from the group name...

Dim GrpName ' name of group

Dim GrpRefNum ' Group reference number

GrpRefNum = GroupIndexGet(GrpName)

Good Luck
