Specifically as follows: Here Delphi with WaveIn ... function to make WAV files The specific code is as follows: Use a window to accept messages from an audio device: unit Unit1;　 Interface uses Windows, Messages, sysutils, variants, Classes, Graphics, Controls, Forms, Dialogs, Stdctrls;　 　　Type TFORM1 = Class (Tform) Button1:tbutton;　 　　Button2:tbutton;　 　　Button3:tbutton;　 　　Procedure For

Inetisoffline function in URL.DLL needs to be introduced.Function declared as:function Inetisoffline (Flag:integer): Boolean; stdcall; External ' URL.

Windows 95/NT provides rich multimedia service functions, including a large number of low-level to advanced multimedia API functions. With these powerful APIs, you can write multimedia applications at different levels. You can write a book about multimedia services. This section briefly introduces some of the most commonly used multimedia services. When developing multimedia applications using Visual C ++, you must include mmsystem in all source progr

is not the actual execution time of a function or algorithm, because it is impossible for the function and algorithm thread to occupy the CPU all the time. It is the same for all functions that determine the execution time, but it is basically accurate, you can perform regular queries. The gettickcount () and clock () functions require realTime Clock time, with interruptions and latency issues. Precision: WindowsNTThe precision of 3.5 and later versions is 10 ms, and its time precision is hig

To control the pop-up and close of the CD-ROM In the Delphi Program, you can use the media control interface function of the mmsystem. Pas unit. Two functions can achieve the same effect. One is the mcisendcommand function, and the other is the mcisendstring function. The opencddrive functions written using these two functions are as follows. 1. Use mcisendcommand:Function opencddrive (isopen: Boolean; drivename: Char = #0): Boolean; VaR OP: tmci_open
