ShellExecute ?

[Dominique Bodin]

Hello, i need some help about this command.
I'm working on a text editor, with syntax colouring, and direct compilation by
another langage called Euphoria.
Then i try to run the compilation process
with the function ShellExecute in this way:
SHELL ENVIRON$("EUDIR") + "\BIN\exw.exe " & ztext
Well, every things work very well at my
home.
But whent i try to execute the prog on
another computer, it doesn't compile at all!
The Eudir environnment variable is correctly
set, the Path is OK ?
At home i own two computer's, one where i
developpe my prog, and another where i
tested the result. Both are executing well !

What append ? ? ? ?

Thanks for an help.

First, I don't know whether or not this is important to your basic question, but the PowerBASIC SHELL function and statement do not use the ShellExecute API.

I assume you mean that it does not run at all, correct? (If it does not compile, that is a completely different problem.)

Do the computers use different versions of Windows? There are subtle differences in the way things like ENVIRON$ and command-line strings are processed by Windows 95/98 vs. NT/2000, so I would check to make sure the strings that are being produced by "EUDIR") + "\BIN\exw.exe " are 100.0% identical. Perhaps you could write the string to a disk file before the SHELL, to make troubleshooting easier.

Next, if the strings are identical, the chances are good that the program is not located where the EUDIR variable says that it is. Perhaps the wrong drive letter is being used?

And perhaps the directory name has a space in it on one machine but not the other. For example:

SHELL "C:\MYDIR\MYPROG.EXE  COMMANDLINE"

...will work but...

SHELL "C:\My Directory\MYPROG.EXE  COMMANDLINE"

...will not. Windows will see the space and try to execute C:\My with a commandline of "Directory\MYPROG... (etc.)".

If that is the problem, you would need to enclose the program name in quotes (CHR$(34)) like this:

SHELL CHR$(34) + ENVIRON$("EUDIR")+"\BIN\exw.exe" + CHR$(34) + " " + zText

Thank's to Eric, and Thierry for help..
I'll have a try and give an answer back
tomorow, cause i'm not at work for now.
The soft i'm working on is a text editor
( one more. . .) for another langage called
( Euphoria ). I've used RichEdit controls ( With the help of some sources code
found on the Forum. ) to edit the text.
I've used another part of Forum sources to
implement color syntaxing.
Everythings works well at home.
The same configuration at work ( everythings
are the same : dirs, paths, env . . . ,the
systems are all Win 98SE 2nd ed .).
Then i was wondering WHY ? ? ?
I will try the two suggestions given to me,
and feedback after.

Another question: during my developpement,
of course everythings didn't work the first
time i compiled it, then i compiled time and
time again... Then now, when i compile the soft with PowerBasic, it compiles but doesn't
run in the same time ( i use the compile and
run Icone of course ! ). If i load another
soft into PowerBasic, it compiles and run
in a good manner !
Someone can tell me why ?

Great regards . . .
