提问by Khayralla
I have code written in C# on a Windows7 and VS2010, 32 bit using .Net 3.5 and it is runing without any problem, now I converted it to 64 bit using .Net 4.0 but I got an error when my code call CloseHandle.
我在 Windows7 和 VS2010 上用 C# 编写了代码，32 位使用 .Net 3.5，它运行没有任何问题，现在我使用 .Net 4.0 将它转换为 64 位，但是当我的代码调用 CloseHandle 时出现错误。
ERROR - CloseHandle
System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.

Any help is appreciated.

You can't use CloseHandlewith a pointer to user memory. You need to allocate a HANDLEin order to close it. What do you expect CloseHandleto close?
您不能使用CloseHandle指向用户内存的指针。您需要分配 aHANDLE才能关闭它。您希望CloseHandle关闭什么？
