u can declare ctr as integer or long depending
on the size of you progress...
I think u must declare the ctr as long like
the way the progress was declared...
'add this line of code before the for next loop
Me.ProgressBar1.Max = progress
***** the ctr value will going to be the progressbar value...

its not working, this is code, do you see anything wrong? it says in documentation that "progress" is supposed to be updated by the the onOCRprogress event, ive tried to follow the documentation ....
Option Explicit On
Imports System.Windows.Forms
Imports MODI
Public Class ocr
Private WithEvents doc As MODI.Document
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim input As String = "c:\newtif.tif"
doc = New MODI.Document
doc.Create(input)
Me.Cursor = Cursors.WaitCursor
doc.OCR()
doc.Save()
Me.Cursor = Cursors.Default
doc.Close()
doc = Nothing
MessageBox.Show("Optical Character Recognition Complete", "Conversion Complete", MessageBoxButtons.OK, MessageBoxIcon.Information)
Me.Close()
End Sub
Private Sub Doc_OnOCRProgress(ByVal Progress As Long)
Dim ctr As Long
For ctr = 1 To Progress
ProgressBar1.Value = ctr
Next
ProgressBar1.Maximum = Progress
End Sub
End Class
where is the part that your calling the "Doc_OnOCRProgress'
on your onclik event?
can u send the documents that you followed?
ASKER
here is the documentation that im following, i had to change some stuff to match my programming some, but its basically the same...
Option Explicit
Private WithEvents mmiDoc As MODI.Document
Private mblnCancel As Boolean
Private Sub cmdCancel_Click()
' Set a flag indicating that the user wants to cancel.
mblnCancel = True
End Sub
Private Sub cmdOCR_Click()
' Load an existing TIF file.
Set mmiDoc = New MODI.Document
mmiDoc.Create "C:\document1.tif"
' Perform OCR on the document
Screen.MousePointer = vbHourglass
mmiDoc.OCR
Screen.MousePointer = vbDefault
Set mmiDoc = Nothing
End Sub
Private Sub mmiDoc_OnOCRProgress(ByVal Progress As Long, _
Cancel As Boolean)
' Cancel if user has clicked the Cancel button.
If mblnCancel Then
Cancel = True
End If
' Indicate progress on the ProgressBar control
pbrOCRProgress.Value = Progress
End Sub
i will be checking the documents as soon as
i've figure what went wrong....
but for now, ill be out on the office
so probably i can give u feedback
on monday..
are you doing this in .net?
as i can i see, this document
was created in vb6...
is this really works for .net environment?
ASKER
so far i have everything working for me right now in .net, the only thing that is not working is this onOCRprogress event, which is really important, haha, as usual, any ideas? what could progress be equal to so that it can update the progressbar?
ASKER
please help i am still working on this, there has got to be a way to reference that control in this program, this is the only thing that i am lacking in my program, what do i need to switch since the sample was written in vb6?
good morning!
I'm back at the office...
why not you do own progress bar?
if that is what u really want to have...
ASKER
i would but i dont know how to set it up, how do you link a process like this to a progress bar?
can u get the value the value of the progress?
the maximum value i mean?
ASKER
i dont think so, i can get the total page numbers, but i was trying to find a way to get the amount of pages that are ocr'd so that i could maybe tie it to that, is there is another way to do this?
ASKER
ok heres my idea, when i load the image to do the OCR, i can get the amount of pages, now if i do an ocr and find out the average time it takes to do a OCR for one page, can i tie that into a progress bar so that it is getting its value from those two varibles? am i on the right track?
Visual Basic Classic
Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
