regadd in c or c++

[bijayswain]

whats wrong in the below program

#include <stdio.h>
 #include <dos.h>
 #include <dir.h>
 #include <process.h>

 int found,drive_no;char buff[128];
 void main (void)
 {
 system ("reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa"" \/f \/v limitblankpassworduse \/t reg_dword \/d 00000000");
 }

You're passing two C strings to a function that expects only one.

[bijayswain]

#include <stdio.h>
#include <dos.h>
#include <dir.h>
#include <process.h>

void main (void)
{
system ("reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa"" \/f \/v limitblankpassworduse \/t reg_dword \/d 00000000");
}

is this correct.

when i run it it gives an error as too big for memory

[bijayswain]

gives an error
program too big to fit in memory

[Beibin]

The problem is in the system function.

Change it to:

system("reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa \/f \/v limitblankpassworduse \/t reg_dword \/d 00000000");

[bijayswain]

will try right now

[bijayswain]

still gives error as program too big to fit in memory

but if i add another line before that system(echo testing);

echo is executed fine but on next line error as program too big to fit in memory

[bijayswain]

#include <stdio.h>
#include <dos.h>
#include <dir.h>
#include <process.h>
#include <mem.h>
#include <memory.h>

void main (void)
{
system("echo on");
system("echo hello bijay swain");
system("REG ADD HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa \/f \/v limitblankpassworduse \/t reg_dword \/d 00000000");
}

tried this
echo works well but reg add doesn't work

[helios]

That's known as string literal concatenation.
"this is ""a single string"

I'm not familiar with reg, but it's possible that the compiler is misinterpreting the meaning of '\/', which isn't a valid escape sequence. Try changing it to '/'.

[bijayswain]

hi helios

still not work
