Using Scanner With VBA


I want to use VBA to get an image from a scanner and then convert the image to text using OCR. I think that VBA can access twain devices without 3rd party software but I don't know where to begin. Can anyone give me a tip?

Hi all



I need to transform informations taken from Form and input into a database.

I gonna distribute some forms in a convention with some questions, the user gonna read and answer.

An example.

1 - What do you think about ... ( ) 1 (x)3 ( )5
2- What about .... ( )1 ( )3 (x)5
........



After that I want to scan those informations.

Any idea how to do it.

I was wondering if VB has a component to read this. After that, I create a standart that make possible read and find the answer by the lengh of each line.


Thank you in advanced

VB And Scanner
Hi guys,

I have to build one application in which the user should have a command button "Scan". By which he can give scan command to the scanner and scanner should print the document and make it available on the form.
I did some R&D and found out that TWAIN driver is used for this kind of features. I had a few questions in mind which i think u people are the best to answer

1) Is there any other driver other than TWAIN?
2)Will using this driver create any complications while packaging?
3)Are the free ActiveX controls available for TWAIN trustworthy or should i buy it from TWAIN official website?
4) Any suggestions how to program it will be very useful

I know questions are too much, but i wanted to clear it one go, so that i dont have to trouble u guys gain

Hope u understand

regards,
kaushik

Using A Scanner
Hello,
Is there a way to turn on a scanner from VB. (I tried using the MS Multimedia control - which MSDN Help said can open a scanner), but couldn't get it to work.

I would prefer this way rather than using the shell() to open up the scanner's interface software.

Thanks a lot.

Resizing (scanner)
This is sort of directx but the main code is vb so ill try here. What i want is a scanner to detect other ships in my game, now what i need is for every like say 1/2 a second, for the box on my scanner to get larger and go from a tiny dot in the middle to the perimeter of the scanner, what i have is:

Public Function scan()
Dim W As Integer
Dim X As Integer
Dim Y As Integer
Dim Z As Integer
Dim Count As Integer
LastTick = GetTickCount
W = 87
X = 200
Y = 92
Z = 205
If W > 0 Then
If GetTickCount > LastTick + 500 Then W = W - 1: X = X - 1: Y = Y + 1: Z = Z + 1
'DrawBox 87, 200, 92, 205, vbGreen
Backbuffer.SetFillStyle (1)
Backbuffer.SetForeColor vbGreen
Backbuffer.DrawBox W, X, Y, Z
LastTick = GetTickCount
End If
End Function

which didnt work, does anyone have any ideas?

Barcode Scanner??
I didn't really know where to ask this question? I was recently working at a local hospital and saw the old program that they were using used a scan gun to scan the barcodes on all medical record folders. The program would scan these barcodes into multiple text boxes. When I saw this I was trying to find information over the internet of how programs would be able to use scanners with programs written in vb today? I thought maybe it would require the use of a driver of some type?

Anyway, i just thought maybe someone has used something like this before and would like to know what they did or what they had to do to use this in a vb program?

UDP Port Scanner
I need to find a way to monitor a UDP port that is already in use.

OS: WinNT

A third party application is sending a data stream through a port that it opens itself. I have not control over that port.

When this third party application freezes up, it hoses my application that is used to print out newsletters. The only way to know for sure that this particular app freezes up, is when the bytes transfered becomes 0.

Thus, I need to monitor the port for when the bytes transfered becomes 0 during a normal operation. This way my secondary app will know when to shutdown and restart the frozen app.

It is vital this shutdown only happens when the bytes transfered reaches 0.

I need to try and do this through code or api's, not using another control such as WinSock.(If Possible)

Thanks

Using A Scanner With TWAIN
Does anybody know how to include code to control a scanner with TWAIN? This in order to allow the user to scan documents and "attach" (I will store only the filename(s) in the database and the images will be stored in a folder) them to the information in a record.
Any reference?

Thanks.

Using A Barcode Scanner
Hi everyone, I'm having a barcode scanner enter a 9 or 10 digit number into a field. What I would like is once the scanner enters the full number into the field the program will automatically run a routine to save the date and time into a database without the user having to press any other buttons. The problem I'm having is I'm using the _Change event in the field and as soon as I scan the barcode only the very first digit is taken and the event is run. Is there a way I can make VB6 wait until all 9 or 10 digits are in the field before it launches the event?

Thanks for everyone's help in advance.
