难解！TAPI(50分)

&nbsp; &nbsp;lineInitialize(lineApp,HInstance,@lineCallback,nil,nDevs);<br>光标停在NIL那里说需要变量<br>我不明白怎么办

你查了msdn 没有啊 你的这个api只能在98下用<br>2000下是另外的LONG lineInitializeEx(<br><br>&nbsp; &nbsp; LPHLINEAPP lphLineApp, <br>&nbsp; &nbsp; HINSTANCE hInstance, <br>&nbsp; &nbsp; LINECALLBACK lpfnCallback, <br>&nbsp; &nbsp; LPCSTR lpszFriendlyAppName, <br>&nbsp; &nbsp; LPDWORD lpdwNumDevs, <br>&nbsp; &nbsp; LPDWORD lpdwAPIVersion, <br>&nbsp; &nbsp; LPLINEINITIALIZEEXPARAMS lpLineInitializeExParams <br>&nbsp; &nbsp;<br>不知道是不是的你自己去看

我试过<br>还是报这个错
