Error when loading table how to avoid

[tvrman]

I'm busy for serveral hours to find the solution for the below issue which
i'm can't solved yet.

When a table is loaded with data like files (filesearch), the table is loaded
with the file names of the current directory, that's works fine.
When i do an reload the table will start at the top and the error starts
with that it's not possible to use dublicate names in the table.
(of course starting with clear table is one solution), what i want is
that the filesnames in the table will stay and not changed anymore,
this make it possible to reload the directory and only the files which added
will be added to the table.
I have tried to errorlabel and create serveral sub's with variable all of them
will not work now. the errorlabel will brake out of the loop and comes never back.

Is there one solution to compare the data from the filesearch with the table and
only the difference or new filenames will be added to the table

You could add duplicate items to a table (unless you have set the column unique property).
I guess that you don't want to show duplicate values.
You can store the file names in an ArrayList and then check if a name exists using: if ArrayList.IndexOf(newFile) > -1 then ...

Greate Erel ,

i have used your advise Arraylist see below code

' load the arraylist to compair.
Arraylist2.Clear
for counter = 0 to table1.RowCount - 1
Arraylist2.Add (Table1.Cell("Files",counter))
next

al1.clear
filesearch(al1,path)
for I =0 to al1.count - 1
s=al1.item(i)

'Compair with exist data in table which is loaded in arraylist2 at the start
If ArrayList2.IndexOf(Substring (s,c,strlength(s)-c)) > -1 then
'..
Else
Table1.AddRow (Substring(s,c,strlength(s)-c),s)
End if

next
