In vc++ you can try the system function:

#include <stdlib.h>  
. . .  
system( "pscp -pw Mypassword file.cfg root@127.0.0.1:/filesys/net/provisioned/file.cfg" );

See also the _exec and _spawn functions.

I wrote like system(_T(" pscp -pw Mypassword file.cfg root@127.0.0.1:/filesys/net/provisioned/file.cfg") )
I got a error error C2664: 'system' : cannot convert parameter 1 from 'const wchar_t [116]' to 'const char

Remove the _T.

I removed _T, error was cleared but its not working.
I just try like this passing three parameters which is file name and IP taken dynamically,

ex: system((" pscp -pw Mypassword \"%s\" root@%s:/filesys/net/provisioned/file.cfg "), m_strFileName, ipAddr.GetAsString());

Getting error C2660: 'system' : function does not take 3 arguments
Is it way to pass the more than one parameter in to system command?

Hi @raghav kuppili ,

If you want to execute multiple commands, you should separate the commands with ;

system("command1; command2; command3");

I think that you should try the simple way using your original command that does not contain '%s' yet: system( "pscp -pw Mypassword file.cfg root@127.0.0.1:/filesys/net/provisioned/file.cfg" ). Use the exact command that works manually from command prompt.

If it works, then you can use functions like sprintf to build the commands dynamically. (You can even ask separate questions regarding strings in C++).

Otherwise, it does not have sense to build the commands dynamically.
