You'll need to add an "autorun.inf" file to the root of your USB-drive. As simple example of this file;
[autorun]
open=myexecutable.exe
icon=someicon.ico
For a list of all options look here[^]. If you wants an editor, look here[^].

Hii,
After searching on for auto update feature to suit my needs/project, i started developing my own auto update feature.
This application basically compares the version of my file and any difference in it, it will download the newest version of that file.
Now problem is , i want to fire or start an .exe application/my main application whenever i find that there is no version update . And close auto update application before starting my different application .
I tried out using system.process.Diagnostic.Process method
But didnt succeeded.
Can anyone show me how i can open different application from my current application and close the current application before starting different application. 
Aspiring Techie,

Proces.Start is the easiest way to start a program.

Did you get an error? If so, what was the message? Can you post the code you used?

Now i have changed the way i used the code.
Now i use my process.start code in Program.cs file.
But it is behaving in a different manner.
static void Main()
{
string appPath = applicationPath();
try
{
if (checkInternetConnection() == true)
{
if (setXML() == true)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Update());
}
else
{
Process.Start(appPath);
}
}
else
{
Process.Start(appPath);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
Process.Start(appPath);
}
appPath is the path of main application retrieved from applicationPath() method.
and setXml() is a method returning boolean value.
Now if update is available.
the application will fire Update Form else it will start my main app.
But instead the application runs , but its control and text are not visible.
When Update Form runs, Form is blank without any controls in it.
I m unable to understand what happens that my controls and heading form becomes invisible during runtime.
Can u sort out the problem?

I can't see any reason here why the Update-form would hide it's controls, unless there's some kind of weird exception.
I wouldn't change the Program.cs, instead, I would have put the Process.Start code somewhere in the Update-form. Perhaps that any of the other members see a potential source of the error?

Since i want either of the form to open. i.e either Update form if update is available or else my main app if there is no update.
Hence i chose it to include process.start code in program.cs file.

The check might take a while, depending on connectivity. I'd still recommend showing a form with a message "Hold on, checking for new cool stuff!".
Alternatively, this worked for me;
Program.cs
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
if (true) <- perform update check here :)
{
System.Diagnostics.Process.Start("Calc.exe");
}
else
{
Application.Run(new Form1());
}
}

i got my mistake, i got the reason why Update form hided its control.
Its because by mistake i commented out the InitializeComponent() method in Update's constructor, that led to hiding of the controls in the form.

Hello All,
Ive got a difficulty regarding opening files in their respective editors...I have to develop an application where I need to say open a pdf file in AcrobatReader,doc file in Word,image in image editor...
Please do let me know if ne1 has solution to this....atleast reference to what i can do to solve this...

Each file-extension has a binding to a program that is used to open them. That's how the Windows Explorer knows that it should start "WordPad" for ".doc" files if you don't have Microsfot Word installed. Once Word is installed, it will use Word, as this gets associated with the file-extension during the installation.
If you just want to "open" the file with the correct editor, then you can simply use "Proces.Start" to start the document - it will open the document with whatever editor the user has associated with the file-extension.
If you want to display the editor-name in, say, a listbox, you'll have to dig deeper.

Why do you have to develop that app when Windows Explorer already does that and comes free with Windows OS?

You will need to write your own code in the Validating event.
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Hi there,
I'm using the .NET 2.0 WebBrowser control in a windows form app, running on XP SP2.
Some of my users are getting the classic 'Access Denied' security exception when dropping into the Document_Completed event handler. I think the exception is happening when trying to access the .Document object of the WebBrowser control.
I know there are issues with frames, and cross domain requests using the WebBrowser control, but the website I'm hitting doesn't use frames and is on the local intranet. When the users try accessing the URL in a normal IE window, it loads fine. Must be something to do with the .Document object and user permissions?
The kicker is that some users are working fine on XP SP2, so I'm thinking it's permissions, any ideas?
Much appreciated,
thanks.

Don't stare at Exception.Message; instead look at the line numbers when you investigate Exception.ToString() and teach your IDE to always show line numbers (Visual Studio: Tools/Options/TextEditor/AllLanguages...), that way you will know exactly what line throws it.

I've solved this now, and here's how I did it, if anyone else has similar issues...
I just added the following code to the OnLoad of the form, after the Navigate() call:
while (wbs.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
I also stopped initialising the browser control with 'about:blank', instead just navigating straight to my target page without going to 'about:blank' first.
I think what was happening is the DocumentCompleted handler was trying to access the wbs.Document property before it was initialised, if thats possible(!), and throwing an error. Weird thing was, this was just happening on some user's PCs, and not others.
Anyway, adding the while loop and removing the load of the about:blank first, seems to have fixed it.

If you have problems with finding the path, this might help you [^]
And since you would be editing you need to set the ReadOnly in Open call to false[^]
