Hello could someone help me get a window text, I currentlu have this script but I cant get the window text

quote:

---

var sTitle;

function OnEvent_MyMediaChange (new_media) {

playerHwnd = Interop.Call('User32','FindWindowW','Winamp v1.x',0);


Interop.Call('User32','GetWindowTextW', playerHwnd, sTitle);


Debug.Trace('Media Info is :'+ new_media + playerHwnd + stitle);

}

---

It is getting playerHwnd correctly but I dont know whats wrong with sTitle.

I have a similiar function in VB6 that is currently working its:

quote:

---

Public Function getWinampSong() As String
    Dim lblWinamp As Object
    'This function will get the song current ' ly playing on Winamp

    If hWndWinAMP = 0 Then
        '~~/\~~ return error code...
        Exit Function
   End If

    Dim lRet As Integer
    Dim sTitle As String * 256
    If hWndWinAMP > 0 Then
        lRet = GetWindowText(hWndWinAMP, sTitle, 256)
       getWinampSong = Left(sTitle, InStr(1, sTitle, vbNullChar) - 10)
   Else
      getWinampSong = "Winamp Not Found"
    End If

End Function

Hope someone can help me.
Thanks.

youre missing the last parameter of GetWindowText (buffer length)

Use GetWindowTextLength to find out how long the buffer should be.

Ok, I have added the buffer
I have just tried the GetWindowTextLength but I guess Im doing something wrong, I get Error: 'stitle' no está definido with GetWindowTextLength too.

quote:

---

sTitle = Interop.Call('User32','GetWindowTextW', playerHwnd, sTitle, 256);

---

But Is says 'stitle' Isnt defined.

I am not sure if this will work as I am at work not home

code:

---

function GetWindowText(hWnd){
    var lBuffer = Interop.Call('user32', 'GetWindowTextLengthW', hWnd);
    var sBuffer = Interop.Allocate(2*(lBuffer+2));

    Interop.Call('user32', 'GetWindowTextW', hWnd, sBuffer, lBuffer);

    Debug.Trace('sBuffer: '+sBuffer.ReadString(0));
}

The syntax is incorrect. GetWindowTextW will return a number of the length of the string, not the string itself. That is what the sTitle parameter is for.

Thank you its working, here is the code in case any one cares:

quote:

---

function OnEvent_MyMediaChange (new_media) {

playerHwnd = Interop.Call('User32','FindWindowW','Winamp v1.x',0);

var lBuffer = Interop.Call('user32', 'GetWindowTextLengthW', playerHwnd);

var sBuffer = Interop.Allocate(2*(lBuffer+2));

var Title = Interop.Call('user32', 'GetWindowTextW', playerHwnd, sBuffer, lBuffer);

Debug.Trace('sBuffer: '+sBuffer.ReadString(0));
}

---

Result is:

sBuffer: 3565. Jay-Z - Aint No Nigga ft. Foxy Brown : "Reasonable Doubt" - Winam


The only problem I got now is that its cutting off the last letter but its good enough.

There is the fixed code, all you need to do is add 1 to lBuffer.
