Hello Mirek!

I found the interesting situation about Global Hotekey:

I want to register global hotkey for Ctrl+C+C and get from clickboard copied data.
I did so:
1. Register system hotkey Ctrl+C

TranslateHotKeyId = Ctrl::RegisterSystemHotKey(K_CTRL_C, THISBACK(GlobalShortCutHandle));

2. in my callback I wrote:


void GoogleTranslatorDemo::GlobalShortCutHandle(){
	if(!AtomicRead(test_test)){
		AtomicWrite(test_test,1);
		
		bool need_translate = false;
		
		if(shortcut_stage==0){
			shortcut_stage = 1; // first Ctrl+C
			time_stop_shortcut.Reset();
		}
		else if (time_stop_shortcut.Elapsed()<600){
			need_translate = true;
			shortcut_stage = 0;
		}
		else {
			shortcut_stage = 1; // first Ctrl+C
			time_stop_shortcut.Reset();
		}
		
		if(need_translate){
			WString cur_text = ReadClipboardUnicodeText();
			
			if(cur_text.GetLength()){
				inputwindow.textedit.Set(cur_text);
				TranslateTextInBaloon();
			}
		}
		AtomicWrite(test_test,0);
	}
}

On the second press Ctrl+C start translating.

The problem:
When I press Ctrl+C from the other application the standard command (copy text) do not react. In other words did not coping the selected text.

How can I do this?
