Ok from what I can understand; You expect the posted code to write something to the console.
It does not and that is to be expected as you're not writing anything. If you want to write something to the console then you should use the Console class[^] e.g. Console.WriteLine("Writing to console");

Thank you Simon. Next question, I was expecting it to print out how many instances of notepad are runnibg, What do I need to do? Thanks.

Console::WriteLine(localByName.Length); will write the size of the array to the console, so the number of the processes will be writen to the console.

Thank you, Simon. I'm getting this message now.
warning C4817: 'System::Array::Length' : illegal use of '.' to access this member; compiler replaced with '->'

Damn, my lack of familiarity with C++/CLI is exposed :P
Replace the . with -> and the warning will disappear

Thank you. Did that no more errors! But no return of data either, even though I have two instances of notepad running. Flashes closed.

I suspect that is because the code you provided here is just written to reproduce your problem and not your actual code.
I've just treid this in my system and these two lines will print the number of notepad processes runnning.

array<Process^>^localByName = Process::GetProcessesByName("notepad" );
Console::WriteLine(localByName->Length);

Member 7766180 10-Sep-11 15:24pm

No its the actual code, however; the console flashes closed quickly and I do think I might of saw a 2 there! I tried System("pause"); but that gave me an error. How do I pause this baby!

Simon Bang Terkildsen 10-Sep-11 15:23pm

Oh I think I know what your problem is now, the console just closes and you don't get to see the output. That is beacuse your program is done running. you can add Console::ReadKey(); to the end of your main() then the program wont terminate before hit a key.

Yes Sir! That did it! Thank you so much for your help!
