wNetGetConnection() issue

[peterk]

Hi Antonio

wNetGetConnection( z: ) returns the correct UNC path for the specified drive but the returned value (which is correct) has a whole lot of garbage chrs appended to it, which I have to remove by finding the first Chr(0) in the returned value and substringing to the chr before that.

Using xHb and fWh version from +- Oct 2006

Peter,

Its strange because the C source code uses lLen to trim it:

WNetGetConnection( hb_parc( 1 ), ( char * ) bBuffer, &lLen );

hb_retclen( ( char * ) bBuffer, lLen );

So it looks as a Windows API wrong behavior. But you got a good workaround

should iLen be DWORD ?

[Antonio Linares]

lLen is an unsigned long wich it is like a DWORD

Code: Select all  Expand view

function Main()

   MsgInfo( Test() )

return nil

#pragma BEGINDUMP

#include <hbapi.h>
#include <windows.h>

HB_FUNC( TEST )
{
   hb_retl( sizeof( unsigned long ) == sizeof( DWORD ) );
}

#pragma ENDDUMP   


It shows .T.

you are right. sorry. i shdnt have bothered you with that.
actually long time back wnetgetuser() function was having the same problem. I used to have a wrapper function truncating upto chr(0). later it got solved on its own. similar problem exists now with this function.
