  Leena,

  I'm still confused. From which computer should the application be uninstalled from The computer hosting the web page or the computer that is viewing the web page

  You could copy the file from the server share to a temp directory on the client machine, then execute it and delete it once execution has completed.

  string strSourceFile = @"\\server\share\filename.exe";

  string strDestinationFile = Environment.GetEnvironmentVariable("TEMP") + @"\filename.exe"

  File.Copy(strSourceFile, strDestinationFile, true)  // the true is a bool value to overwrite if exists

  Process myProcess = new Process();

  myProcess.Start(strDestinationFile);

  myProcess.WaitForExit();

  File.Delete(strDestinationFile);

  I hope this helps you.

  So how is it done indirectly
  
  We have the same issue. Our users have installed say program A, B and C locally and want to see icons for these programs on a page on our intranet. They want to click and start these programs from the icons instead of finding these programs in the start menu.
  
  I once did this through an ActiveX component. What I didn't implement was a way to white list programs the component could start in case someone wanted to run format c: or something. So I removed it and I'am wondering how I can write a similar component, but this time in C#.

  It sounds like you are trying to execute code on the clients machine from a web page. You cannot do this directly and you should not try to do this. If you need to uninstall something, you need to have the user download the exe and then run it locally on their machine manually.

  What are you trying to achieve Do you want to run the application on the client or server side

  If its the former, you won't be able to do that as the Process code runs on the service side. If you are trying to start up Outlook Express for emailing purposes try using the mailto protocol, for example: mailto:mail@mydomain.com

  If its the later, this is typically a very bad idea, imagine if a hundred users pushed the button at the same time; you have a very 'denial of service' attack waiting to happen.

  Hi Leen

  I dont know if this is a good idea but one of the ways to do this is create a Managed C++ class that has a public function receiving a system command. In this public function you excute the system command by calling the C system() function.  Compile this class to a DLL and reference this DLL from your C# application to call the Manages C++ public function directly. By doing this, you can activate your EXE from a button click. 

   

  Declaration:

  int system(const char *string);

  The command specified by string is passed to the host environment to be executed by the command processor. A null pointer can be used to inquire whether or not the command processor exists.

  If string is a null pointer and the command processor exists, then zero is returned. All other return values are implementation-defined.

  Hi David,
   I have taken example of outlook express...Actually we have some.exe which uninstalls some software which are no more required.
  Right now we are manually running that exe, (& Do not want our end users to access that exe)
  I want anybody who clicks the button on webpage, that exe should be run and uninstall respective software from that machine.
  How to achieve this, is there any other way to do that
  Thanks
  Leena
