how to remove a number from a list controlling a table

[achfire]

i'm controlling data that enter to a table by using a specific one from them,let's call it "number of the user", when a client has the num 5 and enters his data ;it will be stocked in the 5th row.i want this number 5 to be removed from the list ,so when a new user try to enter num 5 he gets a message"number already used" so he have to enter a different number than 5,for instance 8,consequently i'll get all his data in the 8th row.

if anyone know a little trick to solve this problem

thanks

Delete from Array will remove an item.

That or maintain a boolean array that will tell you if a number has been picked before.  If element 2 is picked, the check if element 2 of the boolean array is True (already picked).  If it is False (not picked), the act on that data and set that boolean element to True.

Wash, Rinse, Repeat.

Hi archifire,

 Please have a look at the block diagram where student details is implemented a table.

There is no need to keep track of anything seperately. Simply check if the requested row has already been filled or not.

adding to others...

• check your specific column of data
• compare empty string of each row using 'for loop'
• index out the results
• fill your drop down list of available user #'s

this number has to be a shared variable,every client is concerned .

"There is no need to keep track of anything seperately. Simply check if the requested row has already been filled or not." i'm not sure if i get your point,because i don't want a new user to even try to fill data in same row,for example 5,the moment he enters 5 in "NR_ORDRE" he gets a message"it's already taken" or use a combo box containing numbers when a client use one it gets deleted for the upcoming client.

would it be better if i replace it with a combo box and fill it with numbers from 1 to 100 ,but i'll need something to remove a number from a combo box when it's already used by a client >> unique number for each client

[altenbach]

Wouldn't it be more useful to instead keep a list of rows that have been used?

[achfire]

how to do that Mr altenbach,by the way i posted the vi in my previous post if you need to see what i'm talking about

thanks
