<br>内容：用LoadLibrary()<BR>但是要知道DLL存放的路径，还有函数的原型。<BR><BR><BR><BR>LoadLibrary<BR>The LoadLibrary function maps the specified executable module into the address space of the calling process. <BR><BR>HINSTANCE LoadLibrary(<BR>&nbsp;&nbsp;LPCTSTR lpLibFileName&nbsp;&nbsp; // address of filename of executable module<BR>);<BR> <BR>Parameters<BR>lpLibFileName <BR>Pointer to a null-terminated string that names the executable module (either a .DLL or .EXE file). The name specified is the filename of the module and is not related to the name stored in the library module itself, as specified by the LIBRARY keyword in the module-definition (.DEF) file. <BR>If the string specifies a path but the file does not exist in the specified directory, the function fails. When specifying a path, be sure to use backslashes (\), not forward slashes (/). <BR><BR>If the string does not specify a path, the function uses a standard search strategy to find the file. See the Remarks for more information. <BR><BR>Return Values<BR>If the function succeeds, the return value is a handle to the module.<BR><BR>If the function fails, the return value is NULL. To get extended error information, call GetLastError. <BR><BR>摘自MSDN<BR>
