If the environment is 32 bit then this translates into a Long data type. If the environment is 64 bit then this translates into a LongLong data type.. This data type should be used for pointers and handles. DimmyLongPtrAsLongPtr

Pointers and handles are 32 bits on 32-bit Windows and 64 bits on 64-bit Windows.To write code that is compatible with both 32-bit and 64-bit versions of Windows, use CWindow::GetWindowLongPtr.RequirementsHeader: atlwin.hSee AlsoC
如果是开发win 32位的应用程序,这个时候需要用到两个32位的勾子函数:GetWindowLong和SetWindowLong。 如果是开发win 64位的应用程序,这个时候需要用到两个64位的勾子函数:GetWindowLongPtr和SetWindowLongPtr。 处理64位的上述两个函数(GetWindowLongPtr和SetWindowLongPtr)兼容32位的应用程序,微软的MSDN解释如下: GetWindow...

pThisand casts it to aLONG,which is a 32-bit integer type. This truncates the pointer and throws away the upper 32 bits of data. Therefore, when read back, the pointer looks like garbage because the top 32 bits were set to zero (or to0xFFFFFFFF, depending on the value of bit 31)...
