Hi there
Could anibody help me out.
1. My program need to know if the user pressed the Ctrl+Alt+Delete.
2. In windows Explorer, when you right-mouse click any file, explorer will pop up a Menu.My question is how to add some item into this Menu. Such like WinZip, when you install Winzip, the Menu will add two item - "Add to Zip" and "Add to *****.Zip" when you right-mouse click any file. How can it do that? I look for solution from registry, I found it do it by a DLL "Wzshlext.dll" and I found it has two function "DllCanUnloadNow" and "DllGetClassObject". But I don't know how to do that. could you tell me?
