how to take  running exe file into vb.net2003  windows application coding ?

I have opened many exe file like(winword.exe,excel.exe,notepad.exe)
I want to move, maximize and  minimize the  word file window, excel file window, etc. that  means exe file  type wise. this is my ideal

Dim a() As Process = Process.GetProcessesByName("iexplore")
Dim b() As Process = Process.GetProcessesByName("notepad")
Dim c() As Process = Process.GetProcessesByName("winword ")
consider the above coding
a will take all opened interexplore file
b will take all opened notepad  file
c will take all opened  winword file .  I know about above coding
I want programming for following format
consider the following programming. this is not correct programming.
this is  imagine of my mind plan for my requirement
I  want to  take any of exe file that is running
Dim d() As Process = Process.GetProcessesByName("any of exe file ")
 if typeofexefile(d(1)=="winword")
          m=d(1).getprocess();
else  if typeofexefile(d(1)=="notepad")
          n=d(1).getprocess();
I know this is not correct programming.
this imagine programme  is   to  understand you   for  my mind expectation  

what is the original  vb.net2003 windows application code  for my above imagine programming expectation    ?
