我一起来讨论一下以下实例每句代码的含义，我们把这个实例的代码全部中文注解掉，做一个非常基础的实例。欢迎大家踊跃参加！
Imports HalconDotNet
Public Class Form1
Dim m_hWindow As HWindow Dim m_hoImage As HObject = Nothing
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
m_hWindow = HWindowControl.HalconWindow
HOperatorSet.GenEmptyObj(m_hoImage)
HOperatorSet.SetColored(m_hWindow, 6) HOperatorSet.SetPart(m_hWindow, 0, 0, 511, 399) HOperatorSet.ReadImage(m_hoImage, "letter.tif") HOperatorSet.DispObj(m_hoImage, m_hWindow)
End Sub
Private Sub ButtonTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonTest.Click
Dim hoRegionThresh As HObject = Nothing Dim hoRegionClosing As HObject = Nothing Dim hoRegionConnected As HObject = Nothing Dim hoRegionSelected As HObject = Nothing Dim hoRegionIntersection As HObject = Nothing
HOperatorSet.Threshold(m_hoImage, hoRegionThresh, 0, 124) HOperatorSet.ClosingCircle(hoRegionThresh, hoRegionClosing, 3.5) HOperatorSet.Connection(hoRegionClosing, hoRegionConnected) HOperatorSet.SelectShape(hoRegionConnected, hoRegionSelected, "area", "and", 80, 1000) HOperatorSet.Intersection(hoRegionSelected, hoRegionThresh, hoRegionIntersection) HOperatorSet.DispObj(hoRegionIntersection, m_hWindow)
End Sub
End Class


Imports HalconDotNet 引用命名空间，但我不知道引用的是哪个的命名空间。
Dim m_hWindow As HWindow Dim m_hoImage As HObject = Nothing 定义这两个变量的意义和作用，为什么要这样定义，那位高手指导一下，感谢！

Imports HalconDotNet 引用的是在halcon安装后的目录下bin\net35里的halcon
Dim m_hWindow As HWindow Dim m_hoImage As HObject = Nothing
hwindow及hobject均是halcon定义的结构体。

Dim m_hWindow As HWindow Dim m_hoImage As HObject = Nothing
hwindow及hobject均是halcon定义的结构体。
这段能不能讲的在通俗一些，感谢！

详细可以看参考手册，halcon里最基本的就是这些结构，例htuple，hobject，rgion等等
如果要运用好halcon，这份资料就须好好的看看，hwindow，himage等是为了在window下编程方便而设出来的，例如，如果你宣告
Dim m_hoImage As HObject 那要把图片放进m_hoImage就要这样写
HOperatorSet.ReadImage(m_hoImage, "letter.tif")
如果你改成宣告
Dim m_hoImage As Himage 把图片放进m_hoImage要改写成这样
m_hoimage.readimage("letter.tif");
这二句的结果是同样的。


感谢您的回复！ 请继续往下讲！我们在期待！

跟我一样，有前劲没后劲
