I didn't see this before, but the problem is because you're not assigning a new object to your class-level listenerSocket. You're defining a new, local one and it's dropping out of scope at then end of this sub:

Private Sub btnListen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnListen.Click
acceptCallBack = New AsyncCallback(AddressOf _
acceptHandler)
Dim listenerSocket As Socket = New Socket( _
AddressFamily.InterNetwork, _
SocketType.Stream, _
ProtocolType.Tcp _
)

Remove the Dim from the listenerSocket line:

listenerSocket As Socket = New Socket( _
AddressFamily.InterNetwork, _
SocketType.Stream, _
ProtocolType.Tcp _
)

Veera,

I'll try to help you but..

What do you mean by "split the wave file"?

Do you want to edit it? .. Or get a section of it? ... or what?

No, to write a virus, even a pretend one, requires a real programming language, not VB6.

Can't be done in VB6. Also, the only way you're going to this is by getting Group Policies and setting up the "Dont run specified Windows applications" policy.

Actually,I have an exe which i get through my close friend
and well he also get the code from somewhere else , is it possible in vc++ or pure window programming under C,
and dave group policies mean the policy editor which we open gpedit.msc in xp and then writing the registry entry or that is something else.

GPEDIT stands for "Group Policy Editor".

Export Datagrid to Excel

22-Jul-05 13:52

I am looking for some direction on how to export a datagrid or Stored Procedure to Excel while in a VB.net application. I don't want to have to publish as a Report (Crystal or Reporting Services) first and then export it to Excel. I want to export the data either from a datagrid or SQL Stored Procedure and put it into Excel.

I see, from The Code Project forum - that exporting a datagrid from C+ and ASP.net has already been done and looks straight forward if my app was written in either of these languages. Both my skills and my app, at this point, are based in VB.net.

Any suggestions or leads would be helpful.

Thanks

Pat

Sending text to an external application

setedivento22-Jul-05 10:51

22-Jul-05 10:51

Hi everybody..I hope you can solve this little problem:
you know when you log into windows 2000/xp as a guest you may sometimes need to run an application as the administrator.To do so,you press the right mouse button holding at the same time the shift key,then it appears a menu called "Run as...",or something like that,and when you finally click on it,it shows a window asking you to insert the username you want to run as(in our case the administrator)and the password.Well,to get to the point:i want to create a program in vb 6 or .net that sends to the textbox titled "Password:" the password text without passing through the clipboard.To do this,i think i can use windows APIs,and it seems the function SetWindowText is enough,isn't it?But my trouble is the SetWindowText function requires the handle of the object to send the text to.So the question becomes:how can i first of all get the handle of the textbox object(and not of the window that contains it nor using the function GetForegroundWindow)?
Can someone please help?
Many Many Thanks
Luke

Or you could skip that garbage and just shell launch your application using the RunAs command line utility, where you can supply it with the username and password of the account you want it to use.

Or you could just use the Win32 API to do the exact same thing as that RunAs shortcut menu. See CreateProcessAsUser[^], CreateProcessWithLogonW[^], CreateProcessWithTokenW[^].

In VB6, you can't do this unless you use WMI. There are problems with using it to uninstall applications though. The call will fail every single time, so the app may be uninstalling, but you'll never know if it completed successfuly or not. Also, you can't use this method on Windows 9x or NT4 SP3 and below.
