<br>内容：以下是一个使用CreateProcess（）的例子：<BR>http://bcbhome.myrice.com/experience/001/exper84.htm<BR><BR>如果要打开一个帮助文件help.chm可以如下：<BR><BR>为“帮助”菜单命令在应用类中添加映射函数如下：<BR>void CXXXApp::OnHelpChm() <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;// TODO: Add your command handler code here<BR>&nbsp;&nbsp;&nbsp;&nbsp;TCHAR exeFullPath[MAX_PATH];&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;::GetModuleFileName(NULL,exeFullPath,MAX_PATH);<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString s=exeFullPath;<BR>&nbsp;&nbsp;&nbsp;&nbsp;int index=s.ReverseFind('\\');<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString path=s.Left(index);<BR>&nbsp;&nbsp;&nbsp;&nbsp;path=path+&#34;\\Help.chm&#34;;<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;ShellExecute(NULL,NULL,LPCTSTR(path),NULL,NULL,SW_SHOW); <BR>}<BR><BR><BR>

<br>内容：CreateProcess是用于调用EXE程序,具体的做法是:<BR><BR>CreateProcess( <BR>LPCWSTR lpszImageName, <BR>LPCWSTR lpszCmdLine, <BR>LPSECURITY_ATTRIBUTES lpsaProcess, <BR>LPSECURITY_ATTRIBUTES lpsaThread, <BR>BOOL fInheritHandles, <BR>DWORD fdwCreate, <BR>LPVOID lpvEnvironment, <BR>LPWSTR lpszCurDir, <BR>LPSTARTUPINFOW lpsiStartInfo, <BR>LPPROCESS_INFORMATION lppiProcInfo); <BR>CloseHandle(lppiProcInfo-&gt;hProcess);<BR>CloseHandle(lppiProcInfo-&gt;hThread);<BR><BR>但CreateProcess和ShellExcute不同,它只能调用进程文件,而不能打开文件.CHM文件的格式我不是很清楚,假如它确实属于可执行文件的话是可以这样调用的.

<br>内容：这是MSDN上的代码，我作了些改动，使其能运行：<BR>将MyApp.exe改为你的程序名字就可以了。<BR>#include &#34;Windows.h&#34;<BR>void main()<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;STARTUPINFO si;<BR>&nbsp;&nbsp;&nbsp;&nbsp;PROCESS_INFORMATION pi;<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;ZeroMemory( &amp;si, sizeof(si) );<BR>&nbsp;&nbsp;&nbsp;&nbsp;si.cb = sizeof(si);<BR>&nbsp;&nbsp;&nbsp;&nbsp;ZeroMemory( &amp;pi, sizeof(pi) );<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;// Start the child process. <BR>&nbsp;&nbsp;&nbsp;&nbsp;if( !CreateProcess( NULL, // No module name (use command line). <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#34;C:\\Program Files\\MyApp.exe&#34;, // Command line. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Process handle not inheritable. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Thread handle not inheritable. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FALSE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Set handle inheritance to FALSE. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// No creation flags. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Use parent's environment block. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Use parent's starting directory. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&amp;si,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Pointer to STARTUPINFO structure.<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&amp;pi )&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Pointer to PROCESS_INFORMATION structure.<BR>&nbsp;&nbsp;&nbsp;&nbsp;) <BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//ErrorExit( &#34;CreateProcess failed.&#34; );<BR>&nbsp;&nbsp;&nbsp;&nbsp;}<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;// Wait until child process exits.<BR>&nbsp;&nbsp;&nbsp;&nbsp;WaitForSingleObject( pi.hProcess, INFINITE );<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;// Close process and thread handles. <BR>&nbsp;&nbsp;&nbsp;&nbsp;CloseHandle( pi.hProcess );<BR>&nbsp;&nbsp;&nbsp;&nbsp;CloseHandle( pi.hThread );<BR>}

<br>内容：打开chm文件还要用这种方式：<BR>CreateProcess( NULL, // No module name (use command line). <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#34;&#34;hh X:\\XX\\XXX.chm&#34;&#34;, // Command line. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Process handle not inheritable. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Thread handle not inheritable. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FALSE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Set handle inheritance to FALSE. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// No creation flags. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Use parent's environment block. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NULL,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Use parent's starting directory. <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&amp;si,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Pointer to STARTUPINFO structure.<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&amp;pi )&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

<br>内容：sorry!<BR>&#34;&#34;hh X:\\XX\\XXX.chm&#34;&#34;多写了一对引号。hh是关联帮助文件的可执行文件名即hh.exe。
