[help] GetWindowText by cirix on 06-28-2006 at 07:17 PM
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)
RE: [help] GetWindowText by segosa on 06-28-2006 at 07:43 PM
Use GetWindowTextLength to find out how long the buffer should be.
RE: [help] GetWindowText by cirix on 06-28-2006 at 07:45 PM
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));
}
quote: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.

Debug.Trace('sBuffer: '+sBuffer.ReadString(0));
}
quote:There is the fixed code, all you need to do is add 1 to lBuffer.
