GetConsoleMode and SetConsoleMode example help

I'm going batty .... !

Wrote this snippet of code in C to block echoing in console window app. It works. Can't get the same thing to work in VB!!! No matter how many times I set the console mode it still echoes... Does anybody have an EXAMPLE of how to switch console input echoing on and off in Visual Basic? Much appreciated!

#include <windows.h>
#include <stdio.h>

int main(int argc, char **argv)
{
char passwd[128];
char usrinput[128];
HANDLE h;
int md;

/* set no echo */
h = GetStdHandle(STD_INPUT_HANDLE);
GetConsoleMode(h, &md);
SetConsoleMode(h, md & ~ENABLE_ECHO_INPUT);

printf("Password:"); fflush(stdout);
fgets(passwd, sizeof(passwd), stdin);

/* reset echo */
SetConsoleMode(h, md);
printf("\n"); fflush(stdout);

printf("got '%s'\n", passwd);
fgets(usrinput, sizeof(usrinput), stdin);
return 0;
}

What does the tilde~ mean before the constant in C++
SetConsoleMode(h, md & ~ENABLE_ECHO_INPUT);

I've got a test version here, but I can't seem to turn it off at the mo...

It's a Bitwise NOT isn't it. I cant work out how to replicate that in VB, I tried
SetConsoleMode hConsole, Not ENABLE_ECHO_INPUT

but that didn't work, i'm still trying....

Hi,

The ~ is a bitwise NOT yes.

This is the VB code snippet which doesn't work. It still echos the input. *SIGH* ....
