Use the CellDoubleClick event handler. It will have an argument e, which is System.Windows.Forms.DataGridViewCellEventArgs type. From there, e.RowIndex will give you the row, and e.ColumnIndex will give you the column. I trust you can take it from there to fetch the data.

I want to share some media files over LAN. I generated a list box which shows the list of files on my computer. I planned that when the user click on any filename mean when the listbox1 selectedindexchanged client computer automatically start VLC media player and start playing that file without asking any manual assistance from client.
I successfully generated file list on listbox1 which provide full path to the file when click on it mean ftp://server/media/filename.mp3
I use this code to activate the VLC media player
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim furl As String = "ftp://speedexbb/media/" & ListBox1.SelectedItem.ToString
With Process1
.StartInfo.FileName = My.Computer.FileSystem.CombinePath(My.Computer.FileSystem.SpecialDirectories.ProgramFiles, "videolan\vlc\vlc.exe")
.StartInfo.Arguments = furl
.Start()
End With
End Sub
Please help that is there anything wrong. as the VLC made error that unable to open file. how can i get ride of this.
I will be gratefull for kind support

Have you tried launching the file, from the FTP server in VLC??
I'm willing the bet that VLC player can't play a file from an FTP server. In that case, you'd have to download the file to the local hard drive, then play the file from that.

When button is clicked it adds an image to picture box.
I need the image to have a number next to it or a rollover hint with the image name and number.
The problem is, when you add more than one of the same image you don't know which one was added first.
All images on 'The Grid' also get listed in a list box where I also need a number next to the name so it can be selected.
Any help is appreciated.
Thanks

I'm not sure what your question is really. Do you have a problem keeping track of the images in the program, or just with the method of showing the information?

OK, here is the situation. In the program I have a number of buttons, when you click on one an image is placed in a picture box which then can be moved and positioned on the screen. The image name is then listed in a list box. If you click another button another image is placed on the screen. If you go back and click the same button again the same image is place on the screen and is listed in the list box with the same name. Is there a way to add a number to the listbox picture name and have it correspond to the same item on the screen.
Thanks

Your best bet is to dispose of the picture boxes, and render a number on top of the images when you render them. Or, just load the image, build a graphics object, draw a number on it, and then put it in your wretched picture box.

Do you have any sample code on how to render a number on top of an image.
Thanks

Hi,
if you are already rendering the image, you can add text to it like so:
Graphics g=myPaintEventArgs.Graphics;
g.DrawImage(...);
g.DrawString(myText, myFont, ...);
But if you want to modify an image to include some text, get its graphics:
using (Graphics g=Graphics.FromImage(myImage)) {
g.DrawString(myText, myFont, ...);
}
myImage.Save(...);

This is the code for one of my buttons which places an image. Does it get added to this section?
Thanks
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim p As PictureBox
p = New PictureBox
Current_item = Item_names.door
p.Image = System.Drawing.Image.FromFile(door_image)
PictureBox1.Left = 84
PictureBox1.Top = 78
PictureBox1.Height = p.Image.Height
PictureBox1.Width = p.Image.Width
PictureBox1.Visible = True
PictureBox1.BorderStyle = BorderStyle.FixedSingle
PictureBox1.Image = System.Drawing.Image.FromFile(door_image)
PictureBox1.Select()
If PictureBox1.Controls.Count > 0 Then
PictureBox1.Controls.RemoveAt(0)
End If
p.Dispose()
End Sub

Hi Tom,
1.
my example code was C# not VB, sorry. VB.NET can do the same with a slightly different
syntax (except for the using statement, which is a shorthand for automatically calling
Dispose when done with an object).
2.
alternative one was about rendering, hence it goes in the Paint handler.
alterbative two was about modifying an existing image, hence it goes anywhere you like
(but such that it gets called only once for any given image)
3.
your code is a mess:
what is p and what is PictureBox1?? p is never really used/shown!
why would you set Top and Left again and again?
are you adding (and removing) Controls to a PictureBox???
4.
I am not exactly sure what it is you want to achieve, but
I concur with Cristian's suggestion to throw out all pictureboxes.

I have one data scraping project where my vb.net 2.0 application will browse pages and will extract information from there. The only problem is the IP address if the site comes to know that any IP is doing this job they block it. There are many softwares out there is in the market which hides the IP . Is there any way I can do this job in my application through code instead of buying any third party component ?
Any help would be precious
Best Regards

Do you understand what the purpose of an IP address is?
It allows servers to identify where the request for a page comes from and where to serve the results to.
This means that the server has to have an IP address supplied to it.
As far as I know all you can do is route yourself through a proxy server if you wish to hide your IP address.
You could write yourself a proxy server application - which is a task I am no expert in.
However that proxy server's IP address could get blocked.
You always pass failure on the way to success.

Written an app to play some sounds for me, in time with a text file I've got displayed.
Uses Microsoft.DirectX.AudioVideoPlayback (April 07 SDK I believe) and consists of an array of 7 Audio objects, where each is set to a particular file by the following:
Imports DXAV = Microsoft.DirectX.AudioVideoPlayback
Dim audioTracks(7) As DXAV.Audio
Private Sub SetSound(ByVal trackID As Byte, ByVal soundName As String)
Dim soundFullName As String = soundPath & soundName & soundExt ' Builds full filename
If IO.File.Exists(soundFullName) Then
audioTracks(trackID) = New DXAV.Audio(soundFullName)
Else
MsgBox("File not found: " & soundFullName & ".", MsgBoxStyle.Exclamation)
End If
End Sub
The actual play/stop actions are simply audioTracks(trackID).Play() and Stop() calls.
However, when I run this, the audioTracks(trackID) = New DXAV.Audio(soundFullName) fails because:
DLL 'C:\..dahdahdah..\Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock.
I've seen LoaderLocks when using multi-threaded apps with calls to Me.Controls but my app is single-threaded.
