ProgressBar not visible

[AHilberink]

Hi,

I have a problem making my progressbar visible.

Could it be a problem using SQL library, making it visible?

The only way I see the progressbar is when I put a MsgBox within the procedure.

I tried: Activity.Addview("ProgressBar1",....) and ProgressDialogShow

Any suggestions?

Thanks,
André

There are two types of ProgressBars. There is a regular ProgressBar view and there is the ProgressBar dialog.
Which one of them do you want to show?

Hi Erel,

I tried both.

Doesn't matter which one I show, just inform that the process is running.
Choose the easiest one.

Part source:

Activity_Create(FirstTime As Boolean)
   If FirstTime Then
      File.MakeDir(File.DirRootExternal,"DVDProfiler")
      ProgressBar1.Initialize("ProgressBar1")
      ProgressBar1.Indeterminate = True
      parser.Initialize
      Activity.AddMenuItem2("Importeren","Import",LoadBitmap(File.DirAssets,"import.png"))
      InitTable      
      SQL1.Initialize(DBFilePath, DBFileName, True)
      SQLTableCreate
   End If

........

Sub ReadXML
   Dim in As TextReader
      
   If File.Exists(XMLFilePath, XMLFile) = True Then
      Activity.AddView(ProgressBar1,60,140,200,200)
      ProgressBar1.BringToFront
      SQL1.ExecNonQuery("DROP TABLE IF EXISTS " & DBTableName)
      SQLTableCreate
      in.Initialize2(File.OpenInput(XMLFilePath, XMLFile),"windows-1252")
      parser.Parse2(in, "Parser")
      in.Close
      ProgressBar1.RemoveView
   
      FetchTitelLijst
   Else
      Msgbox("XML bestand niet gevonden.","")
   End If
End Sub

I hope you can help.

Thanks,
André

1. You should create the UI whenever Activity_Create is called. Not just when FirstTime is true.
2. You should call DoEvents to allow the progress bar to appear and rotate. You may need to call it more than once.

Hi Erel,

Thanks, I got work now.

Hi Erel,

It looks like DoEvents slows the programm down.

Is this correct or did I something wrong?

You should not call DoEvents many times. If you have a long loop then you should call DoEvents every x iterations.
