Windows system functions with callback

Hi,
is it possible to use windows system functions which need a callback routine as a parameter?
In this case i would like to use EnumWindows, out of bm.

I know this could be done with a c code but is it possible with native bm code?

I would have used the search function of this board, if it would work ;-)

Try this...

Extern "win32"
 Function EnumWindows(Callbackptr:Byte Ptr,lParam)
 Function GetWindowText(hWnd,lpString:Byte Ptr,nMaxCount) = "GetWindowTextA@12"
End Extern

Global CharBuffer:Byte[255]

'The callback function
Function EnumWindowsProc(hwnd,lParam)
 
 GetWindowText(hwnd,CharBuffer,255)
 Print "("+hwnd+") / "+String.FromCString(CharBuffer)

 'Return True if you want to fetch the next window, return False to tell EnumWindows to stop.
 Return True
End Function

EnumWindows(EnumWindowsProc,0)

Thanx a lot.

I tried it with the EnumWindowsProc as a method in a type, which doesn't work.

But as a function it seems to work.
