running application on client machine

I have developed two applications, one ASP.NET web application (myWebAppl) and one windows application (myWinAppl).

myWebAppl Details : This application has two web pages myPage1.aspx and myPage2.aspx.

myWinAppl Details : This is a single instance windows application, which accepts some parameters.

Now from myPagep1.aspx (depending on the requirement) I want to check whether myWinAppl is installed on client machine or not

• if it is installed, I want to run myWinAppl and pass the required para开发者_运维问答meters.
• if it is not installed, the web page should prompt the user that myWinAppl is not installed on your machine, so download it from server.

How do I do this?

You client application should have a script safe ActiveX COM component. In your page, through Javascript (so client-side), you try to instantiate that ActiveX and to execute your desired code with parameters.

If your myWinAppl has Windows Installer package, you can use MSI scripting interface to determine if your app is installed using client-side javascript on web page. Also this interface can let you find out where application is installed. But custom ActiveX object is much easier to use.
