delete groups

[portas]

Hello,

i have 805 groups in my data and in some cases there are less then 805 groups (for example 801).

now i have a script for deleting all groups except the first group.

my problem is:

If in my data are only 801 groups, the script stops and say (i use an invalid value: allowed are values form 0 to groupcount)

how can i solve this problem?

here is the scirpt i use for that:

number = 2                                 
for gruppe = number to 809
    do
    number = number+1
if zahl <= 809 then
       Call GroupDel(gruppe)
       call msglinedisp("delete group Nr. "+str(zahl))
end if
   loop until (number>809)

hope anyone can help.

thank you

Hi portas,

why don't you write someting like this:

dim i

for i=2 to groupcount
  Call GroupDel(groupcount)
  call msglinedisp("delete group Nr. "+str(groupcount))
Next

If you have files and just want to load the first group you can just use selective loading instead.

Option Explicit
Call DataFileLoadSel("example.TDM","TDM","[1]/*","Load")

This can also be used to load a group with a specific name or multiple groups of a single file.

Maybe this will spare you the delete.

Hello Philipp K.,

ich glaube, das funktioniert soweit. Ich werde es die Tage nochmals testen.

Danke

When deleting channels or Groups. It usually works best to delete from the highest number to the lower numbers.  (Each time a group or channel is deleted, the group or channels numbers all change, and will make the numbers incorrect.)

Hi Paul,

you are absolutely right.

you should use a reverse counting loop for that.

Thank you very much.
