You can't.
The code will be executed on the server, not the client.
You cannot run programs on the client from server (i.e. C#) code - security prevents that to stop malicious sites from damaging your computer.

Any application the C# code executes will not be even slightly visible to the user. It appears to work in development because the client and server are the same computer - as soon as they become separate PCs, it fails.

Thanks for your response is there any other solution to solve this?

In practice - no.
In theory, yes: you can use an ActiveX control to run the app on the client PC. *BUT* that only works in IE, not in any other browser, and only when ActiveX controls are enabled - which they aren't by default to prevent web sites running applications on user computers... So while you could do it in theory - in practice it would only actually work on 0.001% of computers, and not at all on phones, tablets, MACs, Linux, etc.

You need to look at a different solution!

Let's clarify: do you want this tool to run on client side or on server side?

If you want on client side, than you got your answer from OriginalGriff: you can't in general (first of all not how you intended to do it). Well, you could under special circumstances, but let's not dig into this until you have clarified (for example using Silverlight full trust: http://silverlightedweb.blogspot.hu/2011/12/how-to-get-unrestricted-access-in.html[^]).

If you want this tool to run on server side, than what you have seen that "in task manager its showing that is its running in background" is exactly what it should happen. IIS is a service running under special user account - even if you specify application pool account and you impersonate that account the you will have different session. So your application won't have a GUI visible to anyone :(. This way you should run only executables that have command line interface and no user interaction is needed.

i dont want any user interactions to be done actually my exe is to compare two files so before starting process i will provide arguments so it will automatically compare and displays result. and i want my tool to run in server

Zoltán Zörgő 20-Aug-13 6:24am

Than what's the actual problem? If you see it running in the background and does what it should do, than you have what you need or not? The "will display the results" part is the problematic one: you won't have GUI at all! So it should either exit automatically or you need a command line tool.

Member 9762654 20-Aug-13 6:29am

i have a button in my tool after clicking that it will display sorry i forgot to mention that

Member 9762654 20-Aug-13 6:26am

my output file from the tool is not created

Check if the user running the process has proper rights. Run a procmon and check where fails, or simply run it as the pool user and see for yourself.

i have a button in my tool after clicking that my output file will be created whether it is possible?

I don't know your tool. Is it available somewhere? But in general such tools are not good to be used is such scenarios.
