Have a look in DelphiLand's Code Snips section. You'll find an article about this, together with the Delphi source code for an example project ;-)

Well it's taken me an hour of searching Delphi help and the internet to find this little gem - how to run an external program from Delphi.
Those searching the net might strike this point a little sooner:
external program
dos
shell
run command
start dos executable
program file
console
command line
run program
dos interpreter

Have the project installed, works well.

I'm starting a BAT file, to do some stuff, which it does nicely, but the DOS window won't close on exit. On any ordinary shortcut, I simply click the close window on exit tick box on the program tab.

I've tried reading as much on ShellExecute in the WinSDK as I can understand, but nothing. Tried setting cwe in command.com section of inf\apps.inf, nothing. Tried the pif files dosprmpt and command in \windows, or properties of them, nope.

So, when you shellexecute, how do you convince windows to close the window on exit?

Ok, so I've found it, answered my own question.
This is arcane, but then this is Windows

Article Q152682

SUMMARY
In Windows 95, the default behavior of the operating system is to keep the console window of an MS-DOS application open if it has displayed text in the window. This provides users with an opportunity to read any messages that may have been displayed in the window before the window is closed. To close a window in this state, you must click the close button (that is, "X") on the window caption or Close on the System menu.

In some instances, however, the user's needs may require that the console window close automatically. The solution is to programmatically remove all the displayed text of an MS-DOS application thereby allowing the console window to close automatically.


MORE INFORMATION
The displayed text of an MS-DOS application can be removed by adding the application to the following .bat file:

@echo off
@cls

Then launch this .bat file instead of the original application. The first line, @echo off, prevents .bat file commands from being displayed in the window. Once the MS-DOS application has completed, the cls command clears any text that may have been sent to the Console window. Thus, because no displayed text has been left in the Console window, the Console window closes after the .bat file has completed.

Could Guido add this snip to the readme for execwait?
