Hi,

I have the following trouble:
I need a function, what automatically recognize, if I one USB Stick reinstecke, and as returnparameter gives me The drive (h:, or F: etc) the USB back.
Erstes part have I already, now Please I but Help... How can I The drive Info rausziehen?

Hilfeseiten for trouble (hopefully)
[...]

so far i see, The & UlParam should include my info, but the can I not treat

my kurzprogramm (XProfan 11 fullversion)
Compile Mark Separation

 $H Messages.ph
Declare Ende%
UserMessages ~WM_DEVICECHANGE
CLS

WhileNot Ende%

    WaitInput

    If ((%UMessage = $219) AND (&UwParam = $8000)) Device setup change (USB reingesteckt)

        print "Hopp"

    endif

Wend

End

means question: What drive letter has the plugged USB?

I hope that here is the right Forum.... oh, and German is not my native tongue, so I Please circa understanding...

Hey, thanks for response !
unfortunately The GetLogicalDrives and GetDriveType functions help I do not

trouble is, if I z.B. already The dritte USB Stick reinstecke, where should the program know,
which was latest?

therefore have I attempts, these Broadcast of windows To reading, but I have so weinge Experience with XProfan (3 Monaten so far.), and can I The Systemvariable &UlParam not read.

but from this modifiziertes Program sees man, the not Empty is !

    If ((%UMessage = $219) AND (&UwParam = $8000)) Device setup change (USB rheingesteckt)

        print "Hopp"
        print &UlParam

    endif

Wend

End

i'm already utterly wonder, what kind of Info enthaltet these Variable
my supposition of msdn.com:

The system broadcasts the DBT_DEVICEARRIVAL device event when a device or piece of media has been inserted and becomes available.

To broadcast this device event, the system uses the WM_DEVICECHANGE message with wParam set to DBT_DEVICEARRIVAL (this is $8000 into View source) and lParam set as described following:
A pointer to a structure identifying the device inserted. The structure consists of an event-independent header, followed by event-dependent members that describe the device. To use this structure, treat the structure as a DEV_BROADCAST_HDR structure, then checked its dbch_devicetype member to determine the device type.

have your / have you got Perhaps ideas, how can I The Info of &UlParam read?
(I knows not whether the one Struct or one area is#... no idea unfortunately

)

Hello Gabor,

mean You something like?
Compile Mark Separation

CLS
userMessages 16//wm_close
subClass %hWnd,1

While 1

    WaitInput
    case %uMessage=16 : break

Wend

End

subClassProc

    if subClassMessage(%hWnd,537) and (&sWParam=$8000)// WM_DEVICECHANGE and DBT_DEVICEARRIVAL

        print "Size:",long(&sLparam,0)
        print "Type:",long(&sLparam,4)
        case long(&sLparam,4)=2 : print "Laufwerksbuchstabe:",unitMask2DriveLetter(long(&sLparam,12))//DBT_DEVTYP_VOLUME

    endif

endproc

proc unitMask2DriveLetter

    parameters unitMask&
    declare s$

    whileLoop 26

        if (unitMask& & 1)=1

            s$=chr$(&loop+64)
            break

        endif

        unitMask&=unitMask& >> 1

    wend

    return s$

endproc

User Messages are here instead of SubClassing less suitable, because a memory the message read becomes, but what is definitely time for message and user messages but ((if too) "zum Glück") shifts/ gestackt einflattern and supplied Speicheradressen not any more consist must if one from this then attempts "verspätet" auszulesen.

with obigem (based on subclassing-) code can I successful my Handy-drive discern. (having no other unit to hand

)

hope it helps. ^^

>> I know not whether the one Struct or one area is#

can only both be a field and it is always - "Struktur" describe ("nur") The order the Information in memory.
