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.
how vital enterprise application are for proactive organizations leveraging collective synergy to think outside the box and formulate their key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line. But of course, that's all a "high level" overview of things

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.

As far as I recall, the Code Project tutorial I referenced was written with C#.
Use "VB.NET and C# Comparison" cheat sheet from (I think) www.harding.edu[^] but in case it wasn't, Google for it.
This should help you to understand what is happening in both C# and VB.net, but as you are just learning, consider downloading the Microsoft PDF e-book that is available to registered users of vb.net 2005 Express Edition.
Also, you might like to get a copy of "VB.NET Fundamentals" from http://www.pdsa.com/[^] this is a free e-book that comes with source code. As I understand, you are required to register with them before they let you have a copy to download.

Hi there.
If you use an Access database here is an example on how to use it.
First add a reference to ADODB.dll
Declare database connection varaible as follow:
Private cnDatabase As ADODB.Connection
Open the database. Note that the DatabaseName must be the full path of the database.
cnDatabase = New ADODB.Connection
cnDatabase.Open(DatabaseName)
Fetch data from the Database:
Dim rsRecord As New ADODB.Recordset
Dim strSql As String
Dim tempValue As Object
strSql = "SELECT * FROM " & TableName
rsRecord.Open(strSql, cnDatabase)
With rsRecord
If Not .EOF Then
tempValue = .Fields("FieldName").Value
End If
.Close()
End With
rsRecord = Nothing
Save data to the database:
Dim rsRecord As New ADODB.Recordset
Dim strSql As String
strSql = "SELECT * FROM " & TableName
rsRecord.Open(strSql, cnDatabase, ADODB.CursorTypeEnum.adOpenKeyset,
ADODB.LockTypeEnum.adLockOptimistic)
With rsRecord
.AddNew()
.Fields("FieldName").Value = YourValue
.Update()
.Close()
End With
rsRecord = Nothing
Hope this wil help you.
