How To Call C Lang. Program Through ASP And Show Output In Html.

I have front end in ASP and I need to call C Language prog. for matrix search program. I have used this code(which I got here)

<SCRIPT language="VBScript" type="text/vbscript">
Function popC
dim wsh
set wsh = CreateObject("wscript.shell")
wsh.run("D:TC
ew.exe")
set wsh = nothing
End Function
</script>

This code works fine but I need to show the output in html (so people can see over the net). .Exe is for command line argument. As I know that command line argument can not be shown to the client.

Is that mean that C prog. needs to create instance and instead of 'void main' write 'string function' which which will have return values and this 'class' I will call in ASP program.
