<br>内容：ShellExecute(<BR>&nbsp;&nbsp;&nbsp;&nbsp;HWND hwnd, <BR>&nbsp;&nbsp;&nbsp;&nbsp;LPCTSTR lpOperation,<BR>&nbsp;&nbsp;&nbsp;&nbsp;LPCTSTR lpFile, <BR>&nbsp;&nbsp;&nbsp;&nbsp;LPCTSTR lpParameters, <BR>&nbsp;&nbsp;&nbsp;&nbsp;LPCTSTR lpDirectory,<BR>&nbsp;&nbsp;&nbsp;&nbsp;INT nShowCmd<BR>);<BR>hwnd <BR><BR>Window handle to a parent window. This window receives any message boxes that an application produces. For example, an application may report an error by producing a message box. <BR><BR>lpOperation <BR><BR>Address of a null-terminated string that specifies the operation to perform. The following operation strings are valid: "open"&nbsp;&nbsp;The function opens the file specified by the lpFile parameter. The file can be an executable file or a document file. It can also be a folder. <BR>"print"&nbsp;&nbsp;The function prints the file specified by lpFile. The file should be a document file. If the file is an executable file, the function opens the file, as if "open" had been specified. <BR>"explore"&nbsp;&nbsp;The function explores the folder specified by lpFile.&nbsp;&nbsp;<BR><BR>This parameter can be NULL. In that case, the function opens the file specified by lpFile. <BR><BR>lpFile <BR><BR>Address of a null-terminated string that specifies the file to open or print or the folder to open or explore. The function can open an executable file or a document file. The function can print a document file. <BR><BR>lpParameters <BR><BR>If the lpFile parameter specifies an executable file, lpParameters is an address to a null-terminated string that specifies the parameters to be passed to the application. <BR>If lpFile specifies a document file, lpParameters should be NULL. <BR>lpDirectory <BR>Address of a null-terminated string that specifies the default directory. <BR><BR>nShowCmd <BR><BR>If lpFile specifies an executable file, nShowCmd specifies how the application is to be shown when it is opened. This parameter can be one of the following values: SW_HIDE&nbsp;&nbsp;Hides the window and activates another window. <BR>SW_MAXIMIZE&nbsp;&nbsp;Maximizes the specified window. <BR>SW_MINIMIZE&nbsp;&nbsp;Minimizes the specified window and activates the next top-level window in the z-order. <BR>SW_RESTORE&nbsp;&nbsp;Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window. <BR>SW_SHOW&nbsp;&nbsp;Activates the window and displays it in its current size and position.&nbsp;&nbsp;<BR>SW_SHOWDEFAULT&nbsp;&nbsp;Sets the show state based on the SW_ flag specified in theSTARTUPINFO structure passed to theCreateProcess function by the program that started the application. An application should callShowWindow with this flag to set the initial show state of its main window. <BR>SW_SHOWMAXIMIZED&nbsp;&nbsp;Activates the window and displays it as a maximized window. <BR>SW_SHOWMINIMIZED&nbsp;&nbsp;Activates the window and displays it as a minimized window. <BR>SW_SHOWMINNOACTIVE&nbsp;&nbsp;Displays the window as a minimized window. The active window remains active. <BR>SW_SHOWNA&nbsp;&nbsp;Displays the window in its current state. The active window remains active. <BR>SW_SHOWNOACTIVATE&nbsp;&nbsp;Displays a window in its most recent size and position. The active window remains active. <BR>SW_SHOWNORMAL&nbsp;&nbsp;Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time. <BR><BR>If lpFile specifies a document file, nShowCmd should be zero. <BR><BR>You can use this function to open or explore a shell folder. To open a folder, use either of the following calls: <BR><BR>ShellExecute(handle, NULL, path_to_folder, NULL, NULL, SW_SHOWNORMAL);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR><BR>
