My JavaScript sends a selected path, for example C:\files to com ActiveX, I catch it on C# like this:

[ComVisible(true)]
  public string MyParam
  {
   get
   {
    return myParam;
   }
   set
   {
    myParam = value;
   }
  }

I then launch a program like this:

[ComVisible(true)]
	    public void LaunchPlayer()
	    {
		    Process.Start("wmplayer.exe", "ANYFOLDER");
	    }

The problem is that how do I launch the program so that it uses the current value on myparam on "anyfolder"?

Wicked. Do people still use ActiveX? I have no experience in that what so ever. Have you tried Stackoverflow?

	    public void LaunchPlayer()
	    {
		    System.Diagnostics.ProcessStartInfo PSI = new System.Diagnostics.ProcessStartInfo();
		    PSI.FileName = "wmplayer.exe";
		    PSI.WorkingDirectory = "C:\\MyDirectory";
		    System.Diagnostics.Process.Start(PSI);
	    }

Unless I understood the OP's question incorrectly, this should do the trick:

Process.Start("wmplayer.exe", myParam);

The second parameter specifies the arguments passed to the executable. If you want to launch the executable with a different working directory, you should follow stumper66's suggestion above and set the WorkingDirectory property accordingly.

Thanks.

Is there anything better that I can use? I use ActiveX so that I can send parameters from javascript to methods in .dll.

From the way you are using it, doubt there is another way other than COM (am I wrong to assume you are actually using COM and not ActiveX which is a variant of COM/OLE and used primarily for shared UI controls?)

Out of curiousity, why are you using JavaScript in the first place?
