Frame控件透明的问题，请帮助修改代码
首先，我在tabcript上边放了一个frame，为了适应xp视觉效果，希望frame背景色能够透明，在网上找到一段代码。但是出现了两个问题。
1，只有在button点击得情况下才能生效。我希望在formload的情况下出现
2，重复点击的话，背景色又恢复到了原始效果。
因为对api不太熟悉，修改不了。请指点

[解决办法]
在 form的show事件里面写
FrameTransparent Frame1
[解决办法]
你在程序中加入下面的一句话，就可以解决“2，重复点击的话，背景色又恢复到了原始效果。”
CtrlDc = GetDC(.hwnd)
lBackColor = Ctrl.BackColor
'========避免重复绘制================================================
if GetPixel(CtrlDc, 0, 0) <> lBackColor then exit Function
’==================================================================
因为执行一次透明操作后， GetPixel(CtrlDc, 0, 0) 的颜色就不等于 lBackColor 了。

至于：1，只有在button点击得情况下才能生效。我希望在formload的情况下出现
是因为在窗体还没有Show之前，系统不会绘制窗体及控件的，可采取一个笨办法：
设置一个 Timer1, 将其Timer1.Enabled = false , Timer1.Interval = 10,然后：
Private Sub Form_Load()
'keine Systemfarben
Frame1.BackColor = &HFF&
Timer1.Enabled = True
End Sub
Private Sub Timer1_Timer()
Command1_Click
Timer1.Enabled = False
End Sub
勉强可以解决以上问题，当然，也许有更好的办法，我还没时间去探究。
