Hi,
I'm using VB.NET 2005 Express, and I want to create a price break DataGrid having three columns, with an unknown number of rows.
In column 0, I want "From"
In column 1, I want "To"
In column 2, I want "Price"
That bit is easy enough.
The complicated bit, for me, is applying a min and max to the "From" and "To" cells. So, for example, if the user has entered ...
From|To|Price
1|9|5.00
... on the first row, when the user comes to add the next row, I want the "From" cell on the new row to only accept a value greater than 9, so the table may look like ...
From|To|Price
1|9|5.00
10|20|4.50
Any help would be greatly appreciated.

You can use the DataGridView1_CellValidated method to validate your numbers.
In this method use code such as the following to accomplish the validating:
If Me.DataGridView1.Rows(Me.DataGridView1.CurrentRow.Index).Cells(0).Value < 9 Then
'handle error
End If

Have you created a Setup project for you application? When I use the Setup wizard it scans the application project for dependencies and adds them to the setup project. When running the setup.exe it installs all the files needed to run your application.

Yes i have created a setup project for my application but not with the wizard, i am going to try using the wizard and see if it helps out better, because i am also using a twain device and it is missing that file also.. Question?.. when i use the wizard..how does it know which application to package?

When the solution is open click File | Add | New Project and select the Setup wizard. In the wizard I normally select Primary Ouput File. When the wizard finishes you can look in the Solution Explorer to verify it added you dependencies.

About all I can tell you at this poiont is to handle the click event of the control that you're painting the circle on. Anything other than that and you'll have to supply a lot more detail.

i am trying to change the name of text boxes in vb.net as they are not in proper sequence 180 of them but it wont let me change name as invalid property textbox21 needs to be textbox40 and textbox40 needs to be textbox21 and so on any ideas
|

If I understand your question correctly, you are trying to change the name of a textbox to a name already in use.
If that is the case, change your naming convention: instead of naming them 'textbox1' through 'textbox180', use something like 'txtbox1' through 'txtbox180'.
Since these objects should not already exist, you won't have a problem.

Well, your basic problem is that your UI sucks. Use a grid if you want a grid. Don't use 180 text boxes if they don't represent a grid.
The other problem is that your naming convention sucks, and that if you want to set the names of your controls, you should do it in the designer, or if you're dynamically creating them, you should put them where you want them in the first place.

I would bet you would be better off doing something like using an image of the seating chart as the background of the Form and handling the click event of the form. Get the mouse corrodinates to deterime which seat was clicked. You would have to do some math so you know how big the x and y range is for each seat but I bet you could figure if each seat is 10 X 10 points, for example, and your mouse click was at x y you could find which seat was clicked. I have never done this but that would be the first thing I look at.

Use the 'Beep' function.
Code sample from Help.
Dim I As Integer<br />
For I = 1 To 100 ' Loop 100 times.<br />
Beep ' Sound a tone.<br />
Next I<br />

Originally, you asked how to beep on alert. Question answered.
If you want to play a WAV file, use the following (modified from version in Help)
<br />
Dim player As New SoundPlayer<br />
<br />
Try<br />
' Assign the selected file's path to the SoundPlayer object.<br />
player.SoundLocation = "C:\Program Files\NetMeeting\TestSnd.wav"<br />
<br />
' Load the .wav file.<br />
player.Load()<br />
player.Play()<br />
Catch ex As Exception<br />
SendToLogText(ex.Message)<br />
End Try<br />
