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.

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 />

There is another way with Visual Studio 2005 that is really easy:

My.Computer.Audio.PlaySystemSound(Media.SystemSounds.Beep)
or
My.Computer.Audio.Play("C:\MySound.wav")

(So if you don't have VS2005 I'm sorry to waste your time)

Converting string to integer

16-Jan-07 4:42

Don't tell me you're actually going ahead with 300+ TextBox's on a form? Bad, really bad, idea.

Hi
Is there a way in vb6 to convert a string to an integer. The string I have will always be numbers. I need to do some maths on the string.

Thanks. There is also one other thing when I try get the filelen of a file that is about 3gb in size it returns a -value that is no were near the correct size. This is waht I need to do the math on but can't because of the incorrect value given by filelen

Dave Kreskowiak16-Jan-07 7:54

16-Jan-07 7:54

FileLen, since it's return value is a Long (32-bit signed Integer), will only work with files that are less that 2 GB in size. For anything larger, you'll have to call into the Win32 API to get the file size. Discussion[^].
