就是Pointer啊。

是对应Pointer类型。<br>如果你转换后不对,应该是你的代码的问题.<br><br><br>举个例子<br>BOOL VirtualProtectEx(<br> &nbsp;HANDLE hProcess,<br> &nbsp;LPVOID lpAddress,<br> &nbsp;SIZE_T dwSize,<br> &nbsp;DWORD flNewProtect,<br> &nbsp;PDWORD lpflOldProtect<br>);<br><br>对应Delphi中的声明<br>function VirtualProtectEx(hProcess: THandle; lpAddress: Pointer;<br> &nbsp;dwSize, flNewProtect: DWORD; lpflOldProtect: Pointer): BOOL;<br> &nbsp;external kernel32 name 'VirtualProtectEx';<br>function VirtualProtectEx(hProcess: THandle; lpAddress: Pointer;<br> &nbsp;dwSize, flNewProtect: DWORD; var OldProtect: DWORD): BOOL;<br> &nbsp;external kernel32 name 'VirtualProtectEx';

谢谢xeen，wr960204<br>既然类型转换没错，那我再从代码上找找原因[]<br>(中午散分)

耶找到原因，果然是自己代码的问题！[8D]（哎，是自己小脑不够发达）<br>散分
