This web site has a vary good listing of all the ADO connection strings.
http://www.able-consulting.com/ADO_Conn.htm
To make a reference to a different version of Ado goto project -> references, and they are called microsoft activex data objects.
To download the lastest version of ADO, you will have to do this for each computer if it's not already installed..

Good luck

Helo
Im planing a project, but one of my requirements is that the app
will auto-update it self. My plan is to have the app checking whith
my server if there are any new program-updates/patches.
Q: Are ther any built-in services witch can help me whit this?
Or can a webservice fix it, having the patch in XML?

I have a problem:
Try make a new custom control(usercontrol1). In this control, you add a listbox which goes beyond the bounderies of you usercontrol1 and insert as many strings so these as well goes beyond the bounderies. That is it, compile it.
Now try add usercontrol1 and a button control to a webform. Since the listbox goes beyond the the bounderies, you add the property (autoScroll = true ) to usercontrol. Compile and run the program. You now use the scrollbar to go to the last element in the listbox and select this. You now push the button, and then you select the second last item in the listbox. Now you will see that the usercontrol scrolls to the top.... WHY? I think it it because the control is being ScrollControlIntoView, but how to prevent that?
Thanks in advance...

and i spell it into VB...
I have now a function which copying the __gc table

But is there other means to acces to the memory,

When you said "managed C++", that eliminated me fromt he discussion. Unless forced to by a job change or corporate policy of my current employer, I have no interest or knowledge in "managed" c++.

Any thoughts on where I can start and where to get the info?

I know this is probably a stupid question, but I just started on this whole VB thing (damn that .NET! Else I wouldn't be learning VB...). So far I've written a program to type a message in one textbox that displays in another textbox as encrypted text, and now I want to add an option to save the encrypted text. Help, anyone?

As I have created one application using Visual Basic.NET, I found out that the application pop-up very slow. I don't know why?
Please help? Thanks!

Check to see if you're compiling in debug mode. I've found that compiling in release mode with optimizations on can decrease initial load time up to 10x.

there is also a known bug in this verson of the dotnet framework involving slow start times.
If you don't have one... try adding an "ASPNET" account to your machine. you can disable the account if you want... it just needs to be there.

Have a look at the ngen.exe util that comes with the .NET Fx.
You should get an immediate benefit.

Hi all!
I made a simple Windows Application (MyApp.exe) that shows a simple form with the system date.
That application adds an icon to the system tray (a notify icon) that has associated to it a simple context Menu (Exit). So far no problems...
My problem is:
If i run MyApp.exe 2,3,4 or n times it adds 2,3,4,n icons to the system tray
 
How can i prevent this in order to if i had already the icon of MyApp in the system tray, and if i click on MyApp.exe the focus goes to the form of MyApp and don't add a new icon to system tray??
Thanx in advance

You just check if your app allready is running with eg. ::FindWindow(...) (you need to P/Invoke it)

Rather than using the FindWindow API, there is a nice .NET way to find out if your app is already running.
If UBound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)) > 0 Then
If this returns true then there is another instance of the process running. What I haven't had time to work out yet is how to activate that existing instance. So if anyone knows off the top of their head how to do that, please comment. I've done plenty of this stuff with API calls in VB6 but I'd prefer to use native .NET as much as possible now.
cya,

In *VB* ??? There are toolkits to do it in C++, but I don't think they exist in VB. They are also commercial products and they are not cheap.
