It's been a long time since i stop using my vb6.
Now i'm using vb2005.
You can store many kind of file into your OLE object field.
THe concept is:
First, you need to read all bytes of your file and put it into an array of bytes.
Last, then you can store this array into your OLE Object. Simple isn't it?
In VB2005 you can do this with a line of code:
--------------------------------------------------------------
Imports System
Import System.IO
Class Streamer
'It will return array of bytes.
Public Function GetByteArrayFromFile(ByVal FileName As String) As Byte()
Return File.ReadAllBytes(FileName)
End Function
'It will make the file form array of bytes.
Public Sub MakeFileFormByteArray(ByVal FileName As String, ByVal ByteStream As Byte())
File.WriteAllBytes(FileName, ByteStream)
End Sub
End Class
--------------------------------
You need to make the routine to retrieve and store the data by your own.
I believe you can do that.
If anyone can convert it to vb6? Plz Helo him
Thanks before

I can display my barcode in my crystal report successfully when i run at crystal report v by using code 128 font.
Unfurtunately, when i want to hook my crystal report in VB.NET form with CRViewer30.CRViewer. The barcode became a string of characters...
Isn't i need to define the code 128 font in my VB.NET form even the barcode can display properly in my crystal report..
Any idea about it?

I see no sign of that. where have you looked ? Did you try google ? Did you search this site ? There are plenty of other barcode articles here, although that was the first one I saw in VB, plenty are in C#.

Try Fontware. I have used them in the past for barcode solutions, including EAN128.

Hi,
I have to write a program that uses a webcam to capture an image of a barcode, then translate it to numbers then search these numbers in a database and update the time that the barcode is imaged.
I'm not a profesional programmer, I think of some ways, but I think all of them lacks something, my biggest problem is I can't find a way to capture & import the image from webcam to my program, can anyone please help me with a code or someway that I can do this task, & I think I saw a barcode translation code somewhere, can anyone please help me with it, tell me if there is any SDKs or codes that do this thing.
I'm totally out of ideas, so if someone can be so kind & give me any ideas I would be very thankful, I use VB.net for writing my code.
Thanks.

Only in the VB.NET forum....
There is an article on reading barcodes on CP, I thought, in C#. You can use DirectShow to get the video from the webcam, there are CP articles on this, also. Either way, I would not have thought a web cam was the ideal device for reading barcodes. Tell your boss to buy a barcode scanner, they deliver the barcode as a number to your code, and they don't cost that much.

That this is the forum to find questions that start with 'I'm not a programmer, but I need to *insert difficult task here*'. People seem to think that if they download VB Express, they can write anything, as if by magic.

Hi there,
I have a bit of a stupid question but I just dont know how to solve it, so here goes:
I am currently busy with an application that uses tree view to traverse between screens, and at the moment I have a form for each screen.
Only the panel part of the screen changes when the user navigates so I want to change my solution to refresh the panel with the appropriate one when the user navigates.
How would I go about doing this?
Thanks,
Igor.

Invalidate() is the call that forces a control to redraw itself, is that what you need ?

Hi All,
Anyone knows how to format email msg body so that it matches with word document?
For example. The word document is using centered text-align, how do I create the msg so that it will send with centered text-align as well?
Thank you

Yes you need to write out HTML and don't forget to set the body format to HTML. Then use a div tag or table tag and set the style property.

Thank you, but how do you know what the text alignment that word uses?
For example:
paragraph 1 (left)
Paragraph 2 (center)
paragraph 3 (right)

Will you kindly stick to your original
thread[^].
Either nobody knows or they haven't had the time to address your question yet.
Take a look at this[^]. It's probably not exactly what you're looking for but it should get you started.
A quick search[^] of the forums might also have provided you with some inspiration.
This sounds angry but it's not meant to be, just trying to show you how to help yourself.
