请教一下关于透明控件和右键弹出菜单的问题。

[supergold]

先说透明控件：
我做了一个透明的窗体，然后在上面放了一个PICTUREBOX和一个LABEL，要怎么样才能把这两个控件设置成透明的啊？窗体我是用GETWINDOWSLONG函数来改变它的样式的。用什么函数才可以得到控件得样式并改变它？
关于右键弹出菜单的问题：
因为这个窗体我想做成没有边框的，也就是我把FORM的borderstyle属性要设成NONE,在不放置菜单的时候是没有边框的，可是在我设置了菜单后，边框又出现了。我把菜单设置成不可见，改为用右键弹出菜单，可是右键弹出是没有问题，可是窗体的边框还在，要怎么样才能把边框除去？

请大家给点指导!谢谢。

label的透明可以这样做：label.backstyle=1

无边框窗体的右键菜单
设计无边框窗体时，如果使用菜单编辑器，就会自动改变成有边框的窗体，此时，可以在另外一个窗体中（一般情况下你的程序应该不止一个窗体的吧，如果真的只有一个，可以利用其他人写的类，添加右键）编辑菜单（VISIBLE属性设为FALSE），然后在本窗体中调用。调用形式如下：
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 2 Then
PopupMenu Form2.mymenu
End If
End Sub

还有个问题，透明是解决了，可是上面的picturebox和label都看不到了，该怎么办阿？

这个是做出透明窗体的代码（社区里别人的），可是我觉得这个好像不是窗体了，只是在原来的窗体周围画了一条线。原来窗体上的控件什么的一个都看不到。感觉是窗体整个都没有了，只剩下个边框一样。哪个兄弟有好的解决办法阿！

5653325兄弟的代码倒是解决了我关于菜单的问题。谢谢!

你可以直接使用透明控件， 不用把控件特意改为透明， 添加部件 Microsoft forms2.0 object library
透明控件把Backstyle改为0-你试试

[supergold]

为什么按照我上面那个透明窗体的程序，在上面放置的控件都显示不出来啊？
