VB.NET中windows窗体控件如何画一个圆
VB.NET没用过
VB6的话用form.circle方法画圆,圆的半径和圆点用form.width或者form.height乘以比例数来得到,然后在form_resize事件中重画圆就可以了
不知道和VB.NET差别大不大

vb.net 怎么吧combobox的边框四个直角变成弧形
可以使用onpaint事件进行重绘使combobox的是边框四个直角变成弧形。这里需要用到gdi+绘制的知识和onpait事件。窗体和combobox设置自动重绘为true即可。你可以参考下gdi的圆角绘制的知识的。这里很容易做到的。希望能帮到你。有疑问继续提问哈。
