Hi,

A customer was point me to an behavior in XppDbg.exe that I think is a bug or at least an undesired behavior.

Test Program:
proc main
local nParams := PCount()
local n
? "PCount() -> " , PCount()
for n := 1 to nParams
   ? "Param " + AllTrim(Str(n)) + ": " ,  PValue(n)
next
inkey(0)
return
------------------
Compiled with debug=Yes

When executed directly from the command line 
test.exe 1 2 3
the CRT show this:
PCount() ->           3  
Param 1:  1              
Param 2:  2              
Param 3:  3              

But when debuging 
XppDbg.exe test.exe 1 2 3
the CRT show this instead:
PCount() ->           4  
Param 1:  test.exe
Param 2:  1
Param 3:  2              
Param 4:  3

Hello Pablo:
good morning.
Xppdbg has an extra parameter before the program name to be executed. 
Please type in the cmd line:  Xbbdbg /?.
Would it be it the problem?

No the trouble is that when the debuger launch the "debuged" program insert the exe name as the first param
take this simple program

proc main( cIni )
? cIni
inkey(0)
return

if you type this on the command prompt
myprogram.exe  config.ini
you will see :  config.ini
if you type this on the command prompt
xppdbg myprogram.exe  config.ini
you will see :  myprogram.exe

so the trouble is that xppdbg start the debuged program with this command line
myprogram.exe myprogram.exe  config.ini
instead of
myprogram.exe  config.ini

Of course the workarround is simple
local cIni :=  iif( IsDebug() , PValue(2) , PValue(1) )
but I think the current behavior is abnormal

Pablo,

I had the same problem, but as far as I know it is fixed with a hotfix.
In my installation it is working correct again.

It's HotFix 36 (a Windows 7 related problem).

Thanks, will try

Hola
Ya había visto ese "inconveniente" de casualidad por haber escrito mal
y lo veras si escribes : xppdbg noexiste.exe 9 Pasa 1


y me hizo recordar que en dos el parámetro 0 era la misma aplicación
