C#中实现代码说明:
private void DrawFlag(object sender, EventArgs e) { MxDrawResbuf param; param = new MxDrawResbuf(); MxDrawPoint point; point = new MxDrawPoint(); point.x = 100; point.y = 100; param.AddPoint(point); MxDrawResbuf ret; ret = (MxDrawResbuf)axMxDrawX1.CallEx("ExApp_AddFlag", param); MessageBox.Show(ret.AtLong(1).ToString()); }
