Windows-equivalent for cocoa declares

I am using the following functions from the Cocoa lib:

//allow for transparency by setting opaqueness false
setOpaque(self.Handle, false)

//set the background completely transparent
setBackgroundColor(self.Handle, clearColor(NSClassFromString(“NSColor”)))

setMovableByWindowBackground(self.handle, 1)

dim newStyle As UInt32 = 0 //no titlebar, not resizeable
if self.Resizeable then newStyle = 8 //no titlebar and resizeable

addChild(Handle, self.Handle, 1)
Now I am trying to port my app to Windows. Is there a windows-equivalent of these functions?
Thanks for an answer.

Thank you, where can I find an overview of these functions? I looked around but couldn’t find something.

For the system calls, you’ll need to look at Microsoft’s documentation. I find it easiest just to do a web search for the function name.

Ok, thank you. This is new to me.
