WinExec("C:\\WINDOWS\\NOTEPAD.EXE",SW_SHOW);
ShellExecute(NULL,"edit","C:\\WINDOWS\\NOTEPAD.EXE",NULL,NULL,SW_SHOWNORMAL);为什么shell将参数由open改为edit两条语句都没反应？？

C:\WINDOWS目录下没有NOTEPAD.EXE吧？

ShellExecute()中edit参数的说明如下：
Launches an editor and opens the document for editing.
If lpFile is not a document file, the function will fail.

ShellExecute()返回值说明如下：
Type: HINSTANCE
If the function succeeds, it returns a value greater than 32. If the function fails, it returns an error value that indicates the cause of the failure. The return value is cast as an HINSTANCE for backward compatibility with 16-bit Windows applications. It is not a true HINSTANCE, however. It can be cast only to an int and compared to either 32 or the following error codes below.
你试下ShellExecute()到底返回了什么。
