在特定窗口上执行 Ctrl-C 而不聚焦它

Question

I have an application to which I want to send the Ctrl - C keys combination. I am trying with SendMesssage , but I know that the application checks for Ctrl - C combination using GetKeyState and GetAsyncKeyState so SendMessage is pretty useless... How can I send the Ctrl - C combination to this window without calling SetForegroundWindow(hWnd) ? I need a solution which works without focusing/bringing to front the window.

I am temporarily using this code (but requires focus):

SetForegroundWindow(hWnd);
SendKeys.SendWait("^(c)");

I am using C#, but C++ code is ok.

A long time ago, back when I was doing Sys Admin automation.. I used AutoIT. It's been a long time, but if you don't mind picking up their .dll...

This is the method I'd use.. it mentions you can send directly to a window/control without focus.. in some cases you can't..
