Or you can just use the following Wink
Code:

%H = @MCI(Set CDAudio Door Open)
%H = @MCI(Set CDAudio Door Closed)

I still don't know how to use all that API stuff... CodeScript, maybe you can explain where you've found it, and how you converted it into VDS code? Thanks. Smile

Yes I could have done that - but simply didnt want to introduce another varable when it is not needed- increased confusion to one who views it - Am i wrong there ?

Skit 3000
I got the idea from a vb code found on a forum - from google cache - lying on my HD for months -may be more. I will post the corresponding VB code :

Code:


Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal _
lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal _
hWndCallback As Long) As Long

Private Sub Command1_Click()
  Dim Dummy As String
  Dummy = vbmciSendString("set cdaudio door open", 0)
End Sub

Private Sub Command2_Click()
  Dim Dummy As String
  Dummy = vbmciSendString("set cdaudio door closed ", 0)
End Sub

Function vbmciSendString(ByVal Command As String, ByVal hWnd As Long) As String
    Dim Buffer As String
    Dim dwRet As Long
    Buffer = Space$(100) ' Create a buffer
    dwRet = mciSendString(Command, ByVal Buffer, Len(Buffer), hWnd)
    vbmciSendString = Buffer
End Function

CodeScript:
I was saying that VDS already has a built in MCI command and function.

Skit:
MSDN is hard to navigate for some people but still a good place to find information on API functions.
APIViewer is a good program.

OK I think I have to read the help file more.
AS u siad that when U can do it with vds - no need for calling the winmm.dll directly. BTW I am Sleep

SKit
If U want to have a standard reference W32.HLP file I think aroung 9 mb or so. But U get good idea as to what a function does.
API viwer is good too and can help U find some latest ones not in the W32.HLP file. and also constants if U dont have VB - API text viewer.

I am also just a starter with APIs

I've found this with the ApiViewer, but it doesn't work complete... Crying or Very sad Can you tell me what I did wrong?

I got some info here too.

Code:
clipboard set,Just some text...

loadlib user32

rem Following line comes out of the ApiViewer
rem Private Declare Function EmptyClipboard Lib "user32.dll" () As Long
%i = @lib(user32,EmptyClipboard,INT:)

  list create,1
  list paste,1
  info |%i|@text(1)|
  list close,1

freelib user32

exit


Btw. I found out that if I don't use the INT: parameter, %i returns nothing...


Thanks Smile

Before calling EmptyClipboard, an application must open the clipboard by using the OpenClipboard function. If the application specifies a NULL window handle when opening the clipboard, EmptyClipboard succeeds but sets the clipboard owner to NULL. Note that this causes SetClipboardData to fail.

Info on EmptyClipboard at MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/dataexchange/clipboard/clipboardreference/clipboardfunctions/emptyclipboard.asp
Code:

clipboard set,Just some text...

loadlib user32
%i = @lib(user32,OpenClipboard,INT:,0)
%i = @lib(user32,EmptyClipboard,INT:,0)
%i = @lib(user32,CloseClipboard,INT:,0)

  list create,1
  list paste,1
  info |%i|@text(1)|
  list close,1

freelib user32

exit

Um Skit,
Are you putting anything on the clipboard first? Also why are you guys trying to do things the hard way? VDS already has the ability to clear the clipboard.

CLIPBOARD CLEAR
