Well .. if you want to see parameters pass to function in EXE .. then simply loads it in any debugger say ollydbg .... then set the breakpoint where the function is called ...then
run until breakpoint is hit .. then look at the "stack windows" .. you will find the parameters passed to your function ...
I have told you a very basic procedure .. many variations can be there .. like manytimes parameters not pushed onto the stack .. they are directly uses thorugh registers like ebx ...
I suggest you read the concept of procedure prolugue and epilogue ..
