How to disable msg about empty USB-drives ? (solved)

[ukoenig]

Hello,

on all FWH-samles about drive-informations, there are messages about empty USB-drives.
Is it possible to disable these messages, because selecting 1 of 4 USB-drives,
I get these messages for the 3 unused drives before a dialog opens calliing aDrives().



aDrives()
It returns an array with all the valid drives ids.
Syntax:
aDrives( [<nType>] ) --> aDrives
This function Returns an array with all the units valid of our system.
Parameters:
<nType> 0 = All drives (default), 1 = Floppy drives only, 2 = Hard drives only
Returns:
<aDrives> The array with the drives ids
Sample:
SAMPLES\TESTDRVS.PRG

Please show a compilable and runnable sample of the problem. I think it can be solved.

Enrico,

just compiled the original sample TESTDRVS.prg

before the dialog opens, I get 4 Messages about empty USB-drives of O, P, Q, R
USB < T > is in use
It happens as soon aDrives() is called :

@ 1, 1 LISTBOX cDrive ITEMS aDrives() SIZE 100, 100 OF oDlg ;
ON DBLCLICK oDlg:End()

Windows 10 installed

The result of TESTDRVS.prg

I could not reproduce the problem. How can I get the messages you are talking about?

Uwe, this code not is perfect, but .....

Code: Select all

function Main()

   local oDlg, cDrive
   local aDrives   := {}  //aDrives()
   local i

   // Execute as an administrator
   // Ejecutar como administrador

   for i = Asc( "C" ) to Asc( "Z" )

      if GetDriveType( Chr( i ) + ":\" ) > 1  .and. File( Chr( i ) + ":\NUL" )
         //? Chr( i ) + ":\"
         if Memowrit( Chr( i ) + ":\A1A2A3A4.txt", "Test" )
             FErase( Chr( i ) + ":\A1A2A3A4.txt" )

             // Unidad disponible
             // Drive available

             AADD( aDrives, CHR( i ) + ":" )
         else

             // Dummy condition
             // Unidad no disponible
             // Protegido contra escritura ?
             // Drive not available
             // Drive write protected?

         endif
      endif
   Next i

   DEFINE DIALOG oDlg FROM 5, 5 TO 20, 60 TITLE "Select a drive"

   @ 1, 1 LISTBOX cDrive ITEMS aDrives SIZE 100, 100 OF oDlg ;
      ON DBLCLICK oDlg:End()

   @ 1, 20 BUTTON "&Ok" OF oDlg ACTION oDlg:End()

   ACTIVATE DIALOG oDlg CENTERED

Cristobal,
thank You very much

it seems all USB-ports are checked calling aDrives()
If the USB is empty, a message is shown < please insert a data-medium >.
Maybe there is somethig like a < autocheck > for USB inside the system-settings ( I don't know )
I'm wondering <A:\> and the <DVD-burner> is empty as well, but NO message.

The message is shown also 4 times, before the MsgAlert is executed.

function Test()
local aDrives := aDrives()

MsgAlert( len(aDrives) )

return( nil )

------------------------

That works ( drive-selection with included USB ) NO messages !!!

AEval( GetLogicalDriveStrings(), { | c | MsgInfo( c ) } )

Uwe, this code work's for me

Code: Select all

   
FUNC Main()
        LOCAL nError := SetErrorMode(1)
        aDrives  := GetALLDrives()  // All disks
        SetErrorMode( nError)
        Xbrowse( aDrives )
RETU
//------------------------------------//
FUNC GetALLDrives( nType )
     LOCAL aDrives := {}
     LOCAL nBitDrives := GetLogicalDrives(), n, cDrive

     FOR n = 1 to 32
         IF lAnd( nBitDrives, 2 ^ ( n - 1 ) )
            cDrive = Chr( Asc( "A" ) - 1 + n ) + ":\"
            IF Empty( nType )
               IF n != 1 .and. Empty( nType ) //.and. GetDriveType( cDrive ) == 2
                  AAdd( aDrives, cDrive )
               ENDIF
            ELSE
               IF n !=1 .and. GetDriveType( cDrive ) = nType
                  AAdd( aDrives, cDrive )
               ENDIF
            ENDIF
         ENDIF
     NEXT
RETU aDrives

Hello,

I finished the one-click BACKUP-section and noticed the following :



Only connected USB-ports are visible. That is OK
But why a harddisk connected to the USB-port < T > changes the type to < 3 >.
I changed the harddisk against a USB-stick and get < 2 >
It seems the return-value is the connected medium and not the port-value.

Uwe

Uwe, you're right function give you media type, not port value.
