帮助:waveOutGetDevsCaps问题 [英] HELP: waveOutGetDevsCaps problem

问题描述

有人可以告诉我为什么当我尝试获得带有线条的音频设备盖时吗

Can someone tell me why when I try to get audio device caps with the lines

int nwaveOutDevs = waveOutGetNumDevs();

if ( nwaveOutDevs ){

	WAVEINCAPS wOC;

	waveInGetDevCaps( 0, &wOC, sizeof(WAVEINCAPS) )
				

	}
}

我得到wOC.wchannels = 65535 ???


感谢您的答复！

i get wOC.wchannels = 65535 ???


thank for your responses!!

推荐答案

尝试以下代码.

Try this line of code.

WAVEINCAPS wOC = {0};

waveInGetDevCaps()返回什么?

What does waveInGetDevCaps() return?

我检查了waveInGetDevCaps()的结果并初始化了wOC var

返回值为MMSYSERR_NOERROR.

i checked the result of waveInGetDevCaps() and initialized the wOC var

the return value is MMSYSERR_NOERROR.

int nwaveInDevs = waveInGetNumDevs();
	
	if ( nwaveInDevs ){

		WAVEINCAPS wOC = {0};

		if (MMSYSERR_NOERROR  == waveInGetDevCaps( 0,&wOC,sizeof(WAVEINCAPS)))
			AfxMessageBox("DONE it!!");

	}

但是调试我得到了

wChannels = 65535

waveOut的故事也一样....

but stll with the debug i get

wChannels = 65535

story is the same for waveOut....
