Caveman,
We don't have a demo project to do that, but you can modify the demo in the following folder to add manual OMR zones:
[LEADTOOLS 14.5 location]\examples\COM\VB\OCR

In the file Main1.frm, do the following:
1. Add the following line to Sub Form_Initialize():
LEADRasterView1.AutoRubberBand = True

2. Write the rubber band event handler as follows:
Private Sub LEADRasterView1_RubberBand() 'Manual Zones
   If (Not ShowOCRErrMsg(True)) Then Exit Sub
   Dim zData As New LTZoneData
   
   LEADRasterView1.ClientToBitmap LEADRasterView1.RubberBandLeft, LEADRasterView1.RubberBandTop
   zData.Left = LEADRasterView1.ConvertX
   zData.Top = LEADRasterView1.ConvertY
   zData.Right = zData.Left + LEADRasterView1.RubberBandWidth
   zData.Bottom = zData.Top + LEADRasterView1.RubberBandHeight
   zData.FillMethod = FM_OMR
   zData.RecognizeModule = RECOGNIZE_MODULE_OMR
   zData.CharacterFilter = CHAR_FILTER_DEFAULT
   zData.Type = ZONE_TYPE_FLOWTEXT
   zData.Flags = 0
   zData.EnableVerificationEvent = False
   zData.SectionName = "Section1"
   
   If RasterDoc.AddZone(PageIndex, -1, zData) = 0 Then
      FindZone = True
   End If
End Sub

You can then draw the zones using the mouse, then save them using the Zone => Export Zones... menu item.

Hello,

I want to be able to draw zone and edit them like it's done in the executable OCRUTL32.exe.

How can I do that?
- When you draw a zone, then a message box appears when you can set the zone properties.
- After if you  click on a zone you can edit it or delete it.

Thanks for you help.

I'm using VB6 and leadtools 14.

Best regards

You can create your own custom
ZONE dialog. You can use Amin's code from above and before setting the ZONE
properties your dialog will appear and you actually set the ZONE values using your dialog rather than hard coding them.

As for the second issue, you can handle it in the Mouse Down event by checking if the ZONE area has been clicked.
