Can't you create a bat file with that exact command and just call the bat file i.e

system("something.bat");

Which is an alternative to system calls on the windows platform...

If it's something particularly old like Turbo C 2.01, then you're probably not using cmd.exe as your command interpreter, but the rather more archaic command.com.

i am using the system() function to do that so my code looks something like

string x;
x = "\"c:\\folder\\file.exe\" -parameter1:value1 -parameter2:value2";
system(x.c_str());

string x; x = "\"c:\\folder\\file.exe\" -parameter1:value1 -parameter2:value2"; system(x.c_str());

so it would run this command ( "c:\folder\file.exe" -parameter1:value1 -parameter2:value2 )

it works fine untill one of the parameters values must include quotes in it like this ( -parameter:"value" )

so when i type the code like this

string x;
x = "\"c:\\folder\\file.exe\" -parameter1:\"value1\"";
system(x.c_str());

string x; x = "\"c:\\folder\\file.exe\" -parameter1:\"value1\""; system(x.c_str());

i get the error :

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.


but if i put the same command line ( with the quoted value of the parameter ) in the windows run , or in CMD , it would work fine, why do i get the error when i try to run it from the system() function ..?!!


i appereciate any help.
