Use of VB.NET's Shell function in C#

jude_wong · June 24th, 2003, 09:59 PM

Hi,

Does anyone know how I can use the VB.NET's Shell function in C#? I understand that there is an equivalent one in the .NET Framework but just could not find out which one.

Thanks.

Best regards,

Jude.

Hi Jude

I did some searching myself and found that it realy is
difficult to find a function that works like VB.Net's Shell.

However being a VC++ guy I know a function a API
called ShellExecute that I have used a lot.
I've used this api in C# as well its pretty simple
here is the declaration code

Code:

        [DllImport("Shell32.dll",CharSet=CharSet.Auto)]
        public static extern IntPtr ShellExecute(
            IntPtr hwnd, 
            string lpVerb,
            string lpFile, 
            string lpParameters, 
            string lpDirectory,
            int nShowCmd );

and this is how you use it

Code:

ShellExecute(this.Handle,"open","notepad","","",3);

I've used 3 as the value for the last perameter.
which maps to SW_SHOWMAXIMIZED;
you can find the values to use for the last
perameter in WINUSER.H located in
whereeveryouhaveintalledit\Microsoft Visual Studio\VC98\Include

The search for the Shell counterpart is still on.

Write back if there is anything else you wanna ask.

Try using System.Diagnostics.Process from framework. It has all the functionality you are looking for.

try this:

using System.Diagnostics ;
...........
...........
Process p = new Process();
p.StartInfo = new ProcessStartInfo("notepad.exe");
p.StartInfo.UseShellExecute = true;
p.Start();

Hello,
My question is can we execute, internal DOS commands like del,copy,ren etc... using System.Diagnostic ?

As illustrated in the examples below DOS commands like notepade.exe or ping.exe can be executed or any other exe files.

How to execute DOS internal command like del and pass the arguments to it ?

TIA
Abhijit

Look into the System.IO namespace for functions pertaining to file operations.
Particularly System.IO.File.

use the static start method of the process class,it accepts two argument which the second one is the arguments..

Code:

            // url's are not considered documents. They can only be opened
            // by passing them as arguments.
            Process.Start("IExplore.exe", "www.northwindtraders.com");
