Introduction I am a beginner of C + +, the introduction all depend on vckbase, fortunately there are a lot of examples suitable for beginners, let me take a lot less detours, in order to give back to everyone, I have recently completed a simple small program to provide to everyone, so that those who have been wandering in the C + + gate with the same people can quickly grasp the essentials, You may wish to take a look at it. This paper is based on the VC knowledge Base, Mr. Yi Yiming's "audio

Wednesday, September 2003 1:24 PM when a certain event is completed, the program sends a specific signal to increase the user interface characteristics of the program, such as when downloading is complete or when a command is selected. The use of a multimedia function, through a VB program to run WAV files is an easy thing. However, the system must install a sound card for this operation. The API function you need is called PlaySound, and the followin

Based on the analysis of the FLV format in the previous article, the FLV format includes file header and file body. Therefore, you can define file header and previous tag size #0 as follows: Const static unsigned char flvfilehdr [] = {0x46, 0x4c, 0x56, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; The file body consists of the tag header and tag data. Therefore, the tag header can be defined as follows: Unsigned char flvtaghdr [] = {0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; Note:

First, map to see the effect: Supported Audio Playback in WAV format starts from API. You can perform any skin replacement on the player. You can select your favorite image for skin replacement.Resource usage is extremely small and installation-free. The interface is implemented using an "interface control skin library". You can download the latest version of "interface control skin library" in my resource list, I will keep updating this

Apple's iPod family does not support common lossless formats-this is a big pity. Of course, there must be some reason why Apple wants to promote its own lossless format (later called ALAC. However, at present, there are still few convertible ALAC conversion software. Today, I searched for this information and found a useful music Conversion Tool. It can basically convert all audio formats into the apple lossless format or other music formats you want. This software is dBpowerAMP Music Converter.
