[hgwi]

本来想让鼠标一进入窗口按钮就自动移开,但为什么鼠标一进入窗口,按钮就不见了,到底是什么地方出的问题呀?请帮帮我谢谢!

我对32位程序不太懂，觉得你对MousePoint.x和MousePoint.y都判断eax,edx是不是不对？
.IF MousePoint.x > eax && MousePoint.x < edx
mov eax,ButtonRect.top
mov edx,ButtonRect.bottom
.IF MousePoint.y > eax && MousePoint.y < edx
invoke GetWindowRect,hInstance,ADDR WinRect
invoke iRand,WinRect.left,WinRect.right
mov ButtonRect.left,eax
invoke iRand,WinRect.top,WinRect.bottom
mov ButtonRect.right,eax
.ENDIF
invoke SetWindowPos,hwndButton,NULL,ButtonRect.left, ButtonRect.right,NULL,NULL,SWP_NOSIZE
.ENDIF

有两个地方可能需要注意
1）就是屏幕坐标和窗体坐标的关系
2）就是可能按钮的鼠标移动的消息你接收不到。

什么运行不了，是编译不了还是运行出错。

我的经验是，如果你的程序出错但能编译成功，一般是指针的问题，就是API中的指针参数你没有写对造成空指针。

仔细看看程序吧。

对呀我把两个参数传送到EAX,EDX中原因是.IF指令必须比较至少含1个寄存器的两个内容
