Good morning, you guys!

I have a personal question I haven’t found yet, so I come here.

What’s the difference between WinExec and ShellExecute at Delphi?

I ask this question because recently I had a problem trying to use the WinExec (tried to install a Windows service, but without success), but when using ShellExecute, the service was installed normally.

What does one have that the other doesn’t? I used Delphi 2010.

The function ShellExecute works like Windows Run menu, and this is your best use benefit, the WinExec already in disuse with the successor CreateProcess.

WinExec performs a simple instruction from another application, an execmplo would open the Windows caculator by clicking on some button inside your application!

Already the ShellExecute is much more complex, it operates up a "file", an example would be you ask to print a particular file from your application! I believe you could install the service with the correct command line!

Edit:

Inside the IDE’s Help you can browse the item Microsoft Windows Plataform SDK and get more details on the Shellexecute, this is not a navigation link, it only serves within Help
