实现放大，缩小，漫游，复位等功能

void CmapwingisTest2View::OnWindowsZoomin()

{

         m_map.SetCursorMode(cmZoomIn); //放大

}

void CmapwingisTest2View::OnWindowsZoomout()//缩小

{

         m_map.SetCursorMode(cmZoomOut);

}

void CmapwingisTest2View::OnWindowsPan()//漫游

{

         m_map.SetCursorMode(cmPan);

}

void CmapwingisTest2View::OnWindowsReset()//缺省放大到首个图层

{

         int numLayer=0;

         numLayer=m_map.GetNumLayers(http://www.my516.com);

         if(numLayer<1)return;

         m_map.ZoomToLayer(0);

}

void CmapwingisTest2View::OnWindowsGlobal()//全球范围

{

         m_map.ZoomToWorld();

}
