iOS Question Progress Bar

[Graeme Mitchell]

I am downloading is a text file that is currently 5001 rows long and 24 columns wide. I am loading the file i downloaded into a multi-dimensional array, its takes a while and I wanted to add some type of progressbar.

I tried a few things but I couldnt get it to update the bar unless I put in a break and halted the program

Sub FillArray       
   partsList = su.LoadCSV(File.DirDocuments, "Database.txt", TAB)
   Dim MyArray (partsList.size,24)As String
   Dim Dummy () As String
   
       For i=0 To partsList.Size -2
           Dummy = partsList.Get (i)
       For j= 0 To 24
           MyArray (i,j)= Dummy(j)
       Next
       Log(i)
   Next

End Sub

Have you tried it in release mode? Which part is the slow part?

Why aren't you use a real database? You can create a SQLite database with 2 million rows and it will load instantly.

 

[Graeme Mitchell]

The slow part is the splitting of the text file into the array.

 

[Erel]

The text file is split in the call to LoadCSV.

The other steps should be fast. Have you tested it in release mode?

 

[Graeme Mitchell]

wow, its like 500 times faster than the debug mode. I don't think i need the progress bar when it loads in 3 seconds

Thanks

See the first sentence in my first answer

Note that it will also be fast in debug mode if you clean the project (Ctrl + P) after you modify the sub.
