求EVC录音程序

[cjyun]

我通过修改VC的录音程序，能在模拟器上录音，但在板子上运行时，却不能录音，我不知道是板子的问题还是程序问题，想参考各位的录音程序。谢谢了！

我截取了一些代码发给你了，能够在SPV和PPC机器上实现录音，希望对你有所帮助

模拟器上可以录音的，PDA上却不行，麻烦各位看一下，找一下错误，谢谢！

不好意思多贴了一遍 void CRecordeDlg::OnStop()

[cjyun]

顶一下

[cherishhu]

帮你顶一下

[crazyeagle]

没做过，帮你顶！

[cjyun]

不行啊，没人帮我啊

[cjyun]

郁闷都是自己在答话

[cjyun]

我疯了，没人会啊，郁闷！！

[无聊客]

我帮你顶下，我做过，但是最近没空帮你看代码，我懒，呵呵

我发到你的邮箱里了,查收
