问题 It goes like this, we need to detect if the display is a Projector (or if the system is connected to a Projetor). the catch is this should be done from within the browser. so is it possible to do so by using an Java Applet Flash ActiveX (this does constrains to a single browser, so not an option) searching so far only reaveals display resolution. expecting if there is something still out there. . . Edit: accecpted answer is for Java Applet approach. hope there may be an easier way through

I have tried starting Powershell as administrator and using that to run the script. No luck. I have tried giving the "everyone" user full control over the COM DLL. No luck. Any ideas? 回答1: The only thing that makes sense to me is that the COM object is the same bit-ness as the class ASP and a different bit-ness than the script

问题 Why it is impossible to expose WPF control as ActiveX directly , without hosting wpf control within WinForms control and then exposing WinForms control as ActiveX? All articles I've read : - WPF User Control in a Dialog System Application - WPF Vista Gadgets using ActiveX post it as a fact? but no one explains why? 回答1: One big reason is that they are entirely different graphics and rendering systems. When you create a WPF Window, it is completely different from a Win32 Window, and therefore
