Reading network pathname (solved)

[driessen]

Hello,

How can I read a full pathname of a network connection?

Example : the drive letter is F:. How do can I get the fulle pathname of the network connection ? (ex. \\COMPUTER1\MAP1\MAP2)

Thanks a lot in advance for any help.

Dear Michael,

You may use WNetGetUniversalName() or adapt this code to Harbour:

Code: Select all  Expand view

Sub abc()
Dim fs As Object
Set fs = CreateObject("Scripting.fileSystemObject")
For Each dr In fs.Drives
msgbox dr.DriveLetter & " - " & dr.ShareName
Next
End Sub

[driessen]

Thanks a lot, Antonio.

Unfortunately, I got an "unknown" external on WNetGetUniversalName.

Michael,

Please try these ones:

Code: Select all  Expand view

function GetDriveLetter( cPath )

   local o := CreateObject( "Scripting.fileSystemObject" )
   
return o:GetDrive( o:GetDriveName( o:GetAbsolutePathName( cPath ) ) )

function GetAName( cDriveSpec )

   local o := CreateObject( "Scripting.fileSystemObject" )
   
return o:GetDriveName( cDriveSpec )

Sorry, Antonio,

It doesn't work.

I tried this :

Code: Select all  Expand view

MsgInfo( GetAName( "O" ) )
MsgInfo( GetDriveLetter( "\\COMPUTER3\C\SOFTWARE\JUDA\DATA" ) )
 

The first results in nothing, the seconds returns "object".

I want to know if 2 folders are the same : "O:\JUDA\DATA" and "\\COMPUTER3\C\SOFTWARE\JUDA\DATA".

There is a networkconnection from "\\COMPUTER3\C" to "O:"

[Antonio Linares]

have you tried like this ?

MsgInfo(GetAName("O:"))

[driessen]

It just returns : "O:"

Can you please try this function?

Code: Select all  Expand view

function UNCNAME( cPath )

   local cDrive, cMap

   cPath    := TrueName( cPath )
   if SubStr( cPath, 2, 1 ) == ":"
      cDrive   := Left( cPath, 2 )
      if Empty( cMap := DRIVEMAP( cDrive ) )
         if File( cPath ) .or. IsDir( cPath )
            cPath := "\\" + NetName() + "\" + cPath
            cPath := StrTran( cPath, ":", "\"  )
         endif
      else
         cPath := cMap + SubStr( cPath, 3 )
      endif
   endif

return cPath

#pragma BEGINDUMP

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

HB_FUNC( DRIVEMAP )
{
   LPCSTR drive = hb_parc( 1 );
   char path[ 80 ];
   DWORD len = 80;

   if ( WNetGetConnection( drive, path, &len ) == 0 ) { hb_retc( path ); }
   else { hb_retc( "" ); }
}

#pragma ENDDUMP

Usage:

Code: Select all  Expand view

? UNCNAME( <your_file_or_folder_name> )

Mr. Rao,

Thank you very much. Your solution is working just fine.

[nageswaragunupudi]

Dear Michael,

You may use WNetGetUniversalName()

This function is based on the above suggestion:

Code: Select all  Expand view

HB_FUNC( UNC_NAME )
{
   DWORD cbBuff = 1000;
   TCHAR szBuff[1000];
   UNIVERSAL_NAME_INFO * puni = (UNIVERSAL_NAME_INFO *) &szBuff;
   DWORD dwRes;
   LPCSTR strPath = hb_parc( 1 );

   dwRes = WNetGetUniversalName( strPath, UNIVERSAL_NAME_INFO_LEVEL, puni, &cbBuff );

   if ( dwRes == NO_ERROR ) { hb_retc( puni->lpUniversalName ); }
   else  { hb_retc( strPath ); }
}
 

Please test

Code: Select all  Expand view

? UNC_NAME( <file_folder_name> )

This code has served me well over the years ..

Code: Select all  Expand view

// where .exe started from is default directory //

cFILE  := GetModuleFileName( GetInstance() )
nSTART := RAT( "\", cFILE )
cDEFA  := SUBSTR(cFILE,1,nSTART-1)

msginfo( cDefa )

Dear Rick, This is not the same?

Code: Select all  Expand view

? cFilePath( hb_argv( 0 ) )

Mr. Rick

Simpler ways of doing:

Code: Select all  Expand view

cFilePath( hb_argv( 0 ) )  // Christobal
// OR
cFilePath( ExeName() )
 

But what Mr. driessen asked is totally different. He wanted to convert the file/path name to UNC.

For example, in my case:

Code: Select all  Expand view

? UNCNAME( "L:\FWH\whatsnew.txt" ) // --> "\\GNRDELL\C\FWH\whatsnew.txt"

Sorry, we were wasting our time re-inventing the wheel.

FWH already has a function
cFileUNC( cLocalName ) --> cUncPath
from FWH 1805
