Hi All,

how to launch an application [say notepad] installed in the client system on button click,..using asp.net?
please respond soon.

browsers do not have permissions to access client system.
you can achieve such tasks to some extend by using ActiveX, but again it's limited to IE browser.

While googling I found one link, here it is.
Just google for ActiveX Articles.

You should not be accessing the client's system.

ActiveX controls will let you break this rule but it is not advisable to do this. ActiveX controls can only be run in Internet Explorer (no other browser can support them) and they are blocked by default. Since ActiveX controls are able to access the client's computer they can do anything with the client's operating system. This means that ActiveX controls are considered highly suspicious since they are favoured by malicious websites. Even if the ActiveX control is not malicious in nature, they may open security holes just by existing on the client's computer.

I highly recommend that you find another way to achieve what you are looking for. Accessing the client's operating system is not a good idea.

Hi Frinny,

Thanks for ur reply...is there any other method to sort this?
i tried with the following code on button click.

Dim Myprocess As Process = New System.Diagnostics.Process
        Myprocess.StartInfo.FileName = "c:\\windows\Notepad.exe"
        Myprocess.Start()
        Myprocess.WaitForExit()

it works fine. but when you access the page from some other system, nothing works. :(
why is it so?

The reason that works on your test system is because that code is being executed Server-Side.

When you try to run that client side, NotePad will open on the server.

Why do you want to open NotePad anyway?
