推荐答案

如果你有1000个字符串10组合框重复，你可能要考虑使用一个所有者绘制组合框的基础上的指数纳入其中借鉴了飞弦你阵列，而不是在组合框中存放它们。方式速度更快，方式更多的内存效率。退房的 DRAWITEM 的在线帮助的方法和 DRAWITEMSTRUCT 的结构。基本上，你会喜欢用做点什么 InitStorage 和 InsertString （由NuSonic提到的）在你的combobx创建1000空白项目，并覆盖 DRAWITEM 提取和绘制所需的串，根据索引，因为它需要绘制

If you have 1,000 strings repeated in 10 comboboxes, you may want to consider using an owner drawn combobox, which draws the strings on the fly based on indices into your array, rather than storing them in the combobox at all. Way faster, way more memory efficient. Check out the DrawItem method and DRAWITEMSTRUCT structure in the on-line help. Basically, you would do something like using InitStorage and InsertString (as mentioned by NuSonic) to create your 1000 blank items in your combobx, and override DrawItem to extract and draw the required string, based on index, as it needs to be drawn.
