If your label in for an asp.net application you need to put in a
which the the HTML version of vbCrLf.

So if this is an asp.net app then your code would look like:
lblScore.Text = "Well done, you got
" & intScoreTop & " out of 10"

If this is a windows app it should work fine.

hi guys?
I am making a POS - Point of sale System - project. I want to read from a barcode reader and match the barcode against a barcode already in the database. I'm really stumped on how to go about it. How can I save a barcode to the database and then match what is in the database to what has been read from the barcode reader.

Please help

A bar code represents a string of characters and numbers. So your bar code reader should scan the bar code and convert it into the string representation. This is the value you would save in the database. Once in string form it should be very easy to compare it with other items in the database.

Hello,

This is very simple. The input of scanning in a barcode is the same as the keyboard input.

If you want to input a barcode value, you just put the cursor in a text box, read in the barcode and the value will be there. Once you have it you can do what you like if it. input into a database, compare with another value etc.

Once the barcode scanner is connected to the computer, you don't have to do anything else.

Hope this help,

Steve

Well it is quite bit intrique. I am still working on it but having hard time to display the textbox next to cursor inside the big textbox. Here is the code it displays the text box according to form's cursor (X and Y) coordinates. WTF | :WTF:

Public Class Form1

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress

If e.KeyChar = Chr(65) Then 'Define CTRL-T instead of chr(65) "A"

Dim tbox As New TextBox
Dim tx As Int32 = Windows.Forms.Cursor.Position.X
Dim ty As Int32 = Windows.Forms.Cursor.Position.Y

Me.Controls.Add(tbox)
tbox.Location = tbox.PointToClient(New Point(tx, ty))

tbox.BringToFront()
End If

End Sub

End Class

The problem with this is that a Textbox cannot contain other controls, like another Textbox. You can have a Textbox appear OVER another Textbox, but that's about it.

Getting the cursor position inside the TextBox is identical to gett it for the form. You just ask the Textbox to convert the coordinates using its PointToClient method. Just replace Me with the name of your instance of the Textbox.

I've never had a problem with this. Am I missing something here? As far as I can tell a textbox can contain other controls.

**EDIT**
I see the child control doesn't scroll with the textbox like it would under a form or other such container. It just sits on top. Now I get it.

Most people expect it to scroll with the Text. Unfortunately, they don't understand that the child textbox isn't part of the text at all.

No.. No.. I didn't want the small textbox to come in the big textbox at all, I just wanted the small textbox to come beside the cursor(I say again not the mouse pointer Laugh | :laugh:

) that is in the big textbox.

The cursor is the mouse pointer. The "caret" is the little binking line in the textbox.
You can get the position of the caret using this:

Dim caretPosition As Point = TextBox1.GetPositionFromCharIndex(TextBox1.SelectionStart)

My mistake, But the code doesn't work.
(it says "GetPositionFromCharIndex" is not a member of System.Windows.Forms.TextBox") Confused | :confused:

Re: Still...

GetPositionFromCharIndex is in the .NET 2.0 Framework and above. This means that your using VB.NET 2003 (.NET Framework 1.1) There is no equivilent in .NET 1.1 and below.

I wrote an article that minimizes the windows app to the tray and also using a notify icon. It is in .net 2.0. The part of the code that minimizes the form is pretty much the same.

add this statment after dim statements and re try again

request.KeepAlive = False

But probably it would be necessary to disabled it on the web server also. WTF | :WTF:
