I am trying to access an external windows .DLL. Here is sample Visual Basic code:

It might be possible -- the code you supplied however won't provide
enough information... are you sure that's the complete code?

Joe, I don't think this is possible directly with VDS, because it seems that this DLL is an ActiveX or OCX one. With VDS, you can only use functions which are defined in Visual Basic as "Public Declare Function FunctionName Lib "dllname.dll" (Parameter1 As String) As Long". But, you might be able to do this with the Gadget DLL... Smile

Thanks for the replies - maybe I will check out VDSUG.dll. Just wanted to see if I was heading in the right direction.

Let us know if you make any progress -- it's an intriguing idea. Yes

Joe,
Does the OCX your trying to use show the image on the screen before the OCR process takes place? In other words does the OCX need a container box on your window to use it?

I don't believe it requires that. It seems that you can simply "create" a document (and load into it a .TIF from disk) and then perform OCR and then do whatever you want with the results.

The documentation for it is here:

Joe,
You do know that this can only be used with Microsoft Office 2003? Since I don't have Microsoft Office 2003 at home I will be trying to build this at work but only people with MS Office 2003 will be able to use this.

Also can you post a example of a *.tif file I can use to do the OCR against?

Yep - only works with Office 2003. That is what I have installed on my computer.

I will attach a sample .TIF -

Thanks for any help or direction.
