　　如何用vb获取指定网页的验证码啊？（可以用webbrowser）
　　在vb中建立一个image,如何让验证码显示在image里面啊？
　　满意答案：
　　在窗体上建立一个text1，一个command1，还有picVlCode和intGetVlCode.
　　
　　
　　
　　窗体代码如下：
　　Private Sub Command1_Click()
　　GetVlCode
　　End Sub
　　'-----------------------------------------------
　　'- 获取验证码(GetVlCode)
　　'-----------------------------------------------
　　Private Sub GetVlCode()
　　On Error Resume Next
　　Dim Buff() As Byte
　　'验证码地址
　　intGetVlCode.URL = Text1.Text
　　'以二进制方式存入buff数组
　　Buff() = intGetVlCode.OpenURL(, icByteArray)
　　With picVlCode
　　'绘制成图片对象
　　.Picture = PictureFromBits(Buff())
　　'描绘到picturebox
　　.PaintPicture .Picture, 0, 0, .Width, .Height, 0, 0, .ScaleWidth, .ScaleHeight
　　End With
　　End Sub
　　模块代码：

　　' 转换验证码图片
