1. Advanced Audio functions.
2. MCI
Playback of audio files in VC
Yang ChenIntroduction
First of all, I have not learned well and feel that I have not been able to fulfill the task assigned by the party.
I haven't watched any sound during the past few days. On the one hand, it seems that we have enough knowledge from the five sub-scripts we have to complete and the bomb program. On the other hand, playing audio in VC is a very
limited? For example, neither of them can play waveforms larger than kb.Audio file.To write an example, you should be clear:Playsound (" ..wav", null, snd_async | snd_loop );// The first parameter is the sound file name, and the last snd_loop indicates loop playback.I feel that it is impossible to use these functions to play two types of music at the same time.Once it is used, the interface of the device is occupied, and the second time it is used, or the interface is snatched from the firstOnc
Usually, how do you deal with sound files in the design of multimedia software? Use the API function sndPlaySound provided by Windows to implement WAV file playback? However, have you ever encountered this situation: when the WAV file is larger than the available memory, the sndPlaySound function can not play!!! So, how do you use MCI to play large audio files?
This article will introduce a method.

The example of this paper describes the process of the initialization of SIM card information in android4.x. Share to everyone for your reference, specific as follows:
During the Phone object initialization process, part of the SIM card's data information is loaded, which is stored in iccrecords and Adnrecordcache. The initialization of the data information of the SIM card is mainly divided into the following steps

After several years of preparation and development, the concept of IoT was quickly recognized worldwide and became one of the core driving forces of the new scientific and technological revolution and industrial revolution. According to statistics from Strategy Analytics, as of the end of 2017, nearly 20 billion IOT and networking devices will be deployed worldwide and 10 billion more devices
between sdio and SD card specifications is the addition of low-speed standards. On the sdio card, only the SPI and one-bit SD transmission modes are required. The target application of low-speed cards supports low-speed IO with minimal hardware overhead.

MCI: MCI is short for the multimedia card interface, that is, the multi-media ca
C # Call mciSendString to play the audio file,
The mciSendString function is a WinAPI used to send string commands to the Media Control Interface (MCI) device.
I. function declaration:
Private static extern long mciSendString (string command, // MCI command string returnString, // buffer that stores feedback int returnSize, // The length of the buffer IntPtr hwndCallback // the handle of the callback window
, when calling these methods, we need to pass the file system address to read and write, and the callback function after reading and writing. The Iccfilehandler notifies the caller after reading the data and passes the return value past .
second, the creation of Iccfilehandler process
because different types of SIM card partitioning information are different, different Iccfilehandler objects are created in uicccardapplication based on the current SIM type:[Java] View plain copy @UiccCardApplicat

In July 1, Microsoft decided not to continue developing kin mobile phones for social network users due to poor sales, according to foreign media reports, but focused on its own Windows Phone 7 mobile phone. Kin mobile phones will not be listed in Europe as planned, because Microsoft is shifting the focus of the team's employees to the Windows Phone 7 smartphone operating system planned to be launched later this year. Andy Lees, head of mobile phone R D at Microsoft, announced the move to Micro

According to Strategy Analytics, in 2013, the average monthly consumption data traffic of global mobile phone users will reach 156 MB. The average monthly consumption of users in North America will reach 843.3 MB, making it the most advanced regional market. The East neighbor Japan wi

In multimedia applications such as desktop video conferencing and videophone, obtaining digital videos is a key prerequisite. Before video for Windows (VFW) appeared, it was extremely complicated to capture digital videos. Microsoft Visual C ++ has been supporting video for Windows (VFW) Since version 4.0, which makes video capture programming very convenient. For multimedia application development, the most popular materials on the market are: mCi (m
