<br>内容：使用ShellExecute，你的情况试试下面的调用：<BR>ShellExecute( NULL , "open" , "netsh" , "-f C:\\ll.txt" , NULL , SW_SHOW );

<br>内容：ShellExecuteEx Function<BR><BR>--------------------------------------------------------------------------------<BR><BR>Performs an action on a file. <BR><BR>Syntax<BR><BR>BOOL ShellExecuteEx(&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LPSHELLEXECUTEINFO lpExecInfo<BR>);<BR>Parameters<BR><BR>lpExecInfo<BR>Address of a SHELLEXECUTEINFO structure that contains and receives information about the application being executed. <BR>Return Value<BR><BR>Returns TRUE if successful, or FALSE otherwise. Call GetLastError for error information. <BR><BR>Remarks<BR><BR>With multiple monitors, if you specify an HWND and set the lpVerb member of lpExecInfo to "Properties", any windows created by ShellExecuteEx may not appear in the correct position. <BR><BR>If the function succeeds, it sets the hInstApp member of the SHELLEXECUTEINFO structure to a value greater than 32. If the function fails, hInstApp is set to the SE_ERR_XXX error value that best indicates the cause of the failure. Although hInstApp is declared as an HINSTANCE for compatibility with 16-bit Microsoft&amp;reg; Windows&amp;reg; applications, it is not a true HINSTANCE. It can only be cast to an int and compared to either 32 or the SE_ERR_XXX error codes.<BR><BR><BR>Note&nbsp;&nbsp;The SE_ERR_XXX error values are provided for compatibility with ShellExecute. To retrieve more accurate error information, use GetLastError. It may return one of the following values:<BR><BR>Error Description <BR>ERROR_FILE_NOT_FOUND&nbsp;&nbsp;The specified file was not found. <BR>ERROR_PATH_NOT_FOUND&nbsp;&nbsp;The specified path was not found. <BR>ERROR_DDE_FAIL&nbsp;&nbsp;The Dynamic Data Exchange (DDE) transaction failed. <BR>ERROR_NO_ASSOCIATION&nbsp;&nbsp;There is no application associated with the given file name extension. <BR>ERROR_ACCESS_DENIED&nbsp;&nbsp;Access to the specified file is denied. <BR>ERROR_DLL_NOT_FOUND&nbsp;&nbsp;One of the library files necessary to run the application can't be found. <BR>ERROR_CANCELLED&nbsp;&nbsp;The function prompted the user for additional information, but the user canceled the request. <BR>ERROR_NOT_ENOUGH_MEMORY&nbsp;&nbsp;There is not enough memory to perform the specified action. <BR>ERROR_SHARING_VIOLATION&nbsp;&nbsp;A sharing violation occurred. <BR><BR><BR>Windows 95/98/Me: ShellExecuteEx is supported by the Microsoft Layer for Unicode. To use this, you must add certain files to your application, as outlined in Microsoft Layer for Unicode on Windows 95/98/Me Systems.<BR><BR>Function Information<BR><BR>Minimum DLL Version shell32.dll version 4.0 or later <BR>Custom Implementation No <BR>Header shellapi.h <BR>Import library shell32.lib <BR>Minimum operating systems Windows NT 4.0, Windows 95 <BR><BR> 摘自MSDN
