Network only works after selecting drive
Posted: Tue Dec 20, 2011 06:52 AM

Hi,

On a network of a client I want to copy files from one PC to an other.
I check if the path exist with

IF file(vNetwerkPath+'\VLD.EXE')

It work very nice, but...
If the client first start the PC, he have to go to the explorer and select the drive before it works. Otherwise is returns False, and I can't copy the files.
The network map is configured that it automatic reconnect after startup.
Does anyone know a solution for this problem?
PS The problem is not only with my program, also other programs need first selecting the drive before it works.

Regards,
Marc

Mark,

This is a very well know Windows-problem.

I have been looking for a solution for many, many years. But unfortunately, I never found one.

What do I tell to my customers ?
I always create a shortcut on the desktop for the mapped drive. And I always tell my customer to doubleclick on this shortcut before doing anything else. If so, he/she is sure that the networkmapping is working fine.

I'm afraid that is the only solution, to my opnion.

Good luck.

Michel,

I already told my customer to do this, but she find it to difficult to remember :roll: and she ask me to try to fix it so she doesn't have to select the drive each time after starting the PC

Marc,

maybe you can use this code snippet to check the connection

Code (fw): Select all Collapse

//--------------------------------------------------------------------------
FUNCTION MapNetworkDrive(cShare, cDevice)
RETURN(WNetAddConnection(cShare,cDevice))

//--------------------------------------------------------------------------

FUNCTION DelNetworkDrive(cDevice)
RETURN(WNetCancelConnection(cDevice,.T.))

//--------------------------------------------------------------------------
#pragma BEGINDUMP

#include <windows.h>
#include "hbapi.h"
#include "hbvm.h"
#include "hbapiitm.h"

#define MAX_FILE_NAME 1024

HB_FUNC( WNETADDCONNECTION )
{
 char cLocal[MAX_FILE_NAME];
 BOOL Result = FALSE ;
 int nLength ;
    if (ISCHAR(1) && (hb_parclen(1) >5) && ISCHAR(2) )
    {
  nLength= hb_parclen(2) ;
  if ((nLength>=2) && (nLength< MAX_PATH-1) )
  {
   memcpy(cLocal, hb_parc(2), 2) ;
   cLocal[2]= '\0';
   Result = ( WNetAddConnection(hb_parc(1),NULL,cLocal) == NO_ERROR) ;
  }
 }
 hb_retl(Result) ;
}

HB_FUNC( WNETCANCELCONNECTION )
{
 char cLocal[3];
 BOOL Result = FALSE ;
 if (ISCHAR(1) && (hb_parclen(1) >= 2))
 {
  memcpy(cLocal, hb_parc(1), 2) ;
  cLocal[2]= '\0';
  Result = (WNetCancelConnection(cLocal,ISLOG(2) && hb_parl(2)? TRUE :
FALSE)== NO_ERROR) ;
 }
 hb_retl(Result) ;
}

#pragma ENDDUMP

/*
nRetCode := WNetAddConnection2(  RemoteName, Password, UserName, LocalName )

   if nRetCode <> 0

      if nRetCode = 85
         // alreday connected

      elseif nRetCode = 67
         msginfo( "RemoteName " + RemoteName + CRLF +;
            "Password  " + Password  + CRLF +;
            "UserName  " + UserName  + CRLF +;
            "LocalName " + LocalName + CRLF +;
            CRLF +;
            "System error 67 - The network name cannot be found" )

      elseif nRetCode = 1219
         msginfo( "RemoteName " + RemoteName + CRLF +;
            "Password " + Password + CRLF +;
            "UserName " + UserName + CRLF +;
            "LocalName " + LocalName + CRLF +;
            CRLF +;
            "System error 1219 - Multiple connections to a server" )
      endif

   endif
*/

kind regards

Stefan,

Thanks for the code. I will try it and let you know the result.
