Hvm tap vs VIF
The pv vm has only one vifx. n. When the PV driver is not installed on the hvm, there are two network interfaces vifx. N and tapx. N, which are actually used as tapx. n.
After the PV driver is installed on the hvm and restarted, tapx. N disappears and vifx. N is used (if not restarted, tapx. N is used)

Controls created with the CreateWindow function, if you want to switch with the TAP key, the simplest way is: the main window has ws_ex_controlparent extension properties, the control has ws_tapstop properties.Then the most important thing is to make a judgment when dealing with the message loop : 1 while(GetMessage (msg, NULL,0,0))2 {3 if(!

Using the ScrollView control in Ngui, you can add and manage subkeys through gird, which generally works normally. But if you put a button as a ScrollView subkey or a button in a subkey, you'll see that the button works, but ScrollView won't scroll when you click on the button. If you remove the Boxcollider component of the button, the ScrollView is normal.The solution to this problem is to add the Uidrag Scroll view script to the button and everything is OK.Unity3d:ngui when there is a button i
