New to Delphi XE2 from Delphi 7 - STUCK

For over 10 years I have been using the ExecuteFile function from the fmxUtils unit.  Upon switching to Delphi XE2, I no longer seem to have that available to me.   WinExec does not work.  CreateProcess gives access violation.  What do I have to do to execute a program? This was something that was always simple to do. Now suddenly it seems rather tricky.  Perhaps it's something in the ASCII to Unicode conversion as all winapi calls seem to be PWideChar instead of PChar.

ExecuteFile was a simple wrapper around ShellExecute()

Please see here some examples on how to use ShellExecute() yourself: http://tekreaders.com/blog/2011/08/03/shellexecute-in-delphi-launch-external-applications/

I know how to use ShellExecute.  Could you please tell me what unit I might need to use for it to be available.  I am already using winapi.windows unit and ShellExecute is not declared there.

I feel silly even asking the question, but I've spent more time trying to run an external program that I've spent writing the rest of the program, and the documentation with XE2 is horrible at best.

Geert, I relate it to you don't need to correct my thank you to MerijnB.  Not sure why you felt the need to speak up about that, since you offered no assistance on my question.  I don't think your condescending comment was at all necessary.  It was humiliating enough to even ask the question.  I don't need for you to rub it in for the sake of making yourself feel better.  I kinda figured that whoever answered the question would have known the answer by previous experience.  Nobody and I mean nobody knows everything.  Everybody is capable of a brain fart once in a while.
