DirectX Based on COM, so a directinput object is used to represent the input device, and a specific device is represented by the directinputdevice object.The actual creation process is to first create a directinput object, and then create the directinputdevice object through the createdevice method of this object.Example:# Include # Define dinput_buffersize 16Lpdirectinput; // directinput objectLpdirectinputdevice lpkeyboard; // directinput DeviceBool initdinput (hwnd){Hresult

It seems that Microsoft Source reader is still quite difficult to use because of its needs. In fact, according to the example provided by Microsoft, You can normally debug the program. The following example shows the source reader code. At the same time, the pointer is used in the hresult createvideodevicesource (imfmediasource ** ppsource) function to correctly export the ppsource, not null. Before debugging, use hresult createvideodevicesource (imfmediasource * ppsource). After the output, pps

a professional relief user as soon as possible, let's start by learning directinput keyboard programming.Directinput InitializationAs mentioned earlier in DirectDraw, Microsoft designed DirectX Based on COM, so a directinput object is used to represent the input device, and a specific device is represented by the directinputdevice object.The actual creation process is to first create a directinput object, and then create the directinputdevice object through the createdevice method of this objec

One, through SQL MailSQL Mail provides a simple way to send and read e-mail messages from Microsoft SQL Server. The principle is to send mail by calling the MAPI subsystem on the server, so the server needs to install MAPI clients such as Microsoft Outlook (which cannot be Outlook Express), and when sending messages, Outlook must be in an open state. The specific setting method can be queried through the Internet.Ii. Use of CDONTSBy invoking the native SMTP service to send mail, IIS and SMTP mus

using the COleDispatchDriver class in MFC. 2, the use of MFC Cidispatchdriver is by reading the type library information in the Msado15.dll, creating a derived class of the COleDispatchDriver class, and then invoking the ADO object through it. 3, directly with the API provided by COM If you use the following code: CLSID clsid; HRESULT hr =:: CLSIDFromProgID (L "ADODB.)
