<br>主题：工作者线程参数传递问题
<br>内容：我在对话框的CPP文件的前部定义了线程的控制函数<BR><BR>UINT MyThreadControlProc(LPVOID pParam)<BR>{<BR>&nbsp;&nbsp; //恢复参数<BR>&nbsp;&nbsp; SHELLEXECUTEINFO *psInfo=(SHELLEXECUTEINFO *)pParam;<BR>&nbsp;&nbsp; //启动分块程序<BR>&nbsp;&nbsp;&nbsp;&nbsp;if(ShellExecuteEx(psInfo))<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .......<BR>&nbsp;&nbsp; //中止线程<BR>&nbsp;&nbsp; return 0;<BR>}<BR><BR>在对话框的某成员函数中<BR>&nbsp;&nbsp; //定义SHELLEXECUTEINFO结构<BR>&nbsp;&nbsp; SHELLEXECUTEINFO ShExecInfo = {0};<BR>&nbsp;&nbsp; ShExecInfo.cbSize = ......<BR>&nbsp;&nbsp; ......<BR>&nbsp;&nbsp; //初始化结构的参数<BR><BR>&nbsp;&nbsp; //启动工作者线程<BR>&nbsp;&nbsp; ::AfxBeginThread(MyThreadControlProc,&amp;ShExecInfo,THREAD_PRIORITY_NORMAL,0,0,NULL);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp; 调试发现传递到控制函数中的SHELLEXECTEINFO的结构参数不同了，就是说psInfo结构的参数与ShExecInfo结构的参数根本不同。<BR>&nbsp;&nbsp; 请高手指点这个问题。<BR>2003-2-21 15:20:22
