下面是我实现窗体淡出的代码,我想问一下:我在程序中加入了以下的代码后淡出的效果出来了,但是却遇到了一个奇怪的问题,如果把textBox放在guoupBox里面的时候,textBox这个控件就看不见,但如果把鼠标移过去,就会变成I形呀,点击,这textBox会显示出来;如果把这textBox放在groupBox外面,就能够正确地显示 ,两种情况textBox均能使用,望高手指点指点。using System.Runtime.InteropServices;
public class Win32
{
public const Int32 AW_HOR_POSITIVE = 0x00000001;
public const Int32 AW_HOR_NEGATIVE = 0x00000002;
public const Int32 AW_VER_POSITIVE = 0x00000004;
public const Int32 AW_VER_NEGATIVE = 0x00000008;
public const Int32 AW_CENTER = 0x00000010;
public const Int32 AW_HIDE = 0x00010000;
public const Int32 AW_ACTIVATE = 0x00020000;
public const Int32 AW_SLIDE = 0x00040000;
public const Int32 AW_BLEND = 0x00080000;
