I am having a problem with a list box on a form. I have a list box that when
I add items to it the text does not show up in the list box. I know thy are
added because the side scroll bar changes and I can scrolll throught the list
box. I can not figure out why the items are not being displayed. I have
checked that the background color and the text color are different. Please
let me know what else could be wrong

推荐答案

你是否肯定你正在添加输入text对吗？ listbox.items.add

方法接受类型对象因此，如果您尝试添加非文本内容的
，则不会产生错误。你能从你的

申请表中提供一些代码吗？

Are you positive you''re adding type "text" to it? The listbox.items.add
method accepts a type "object" so it wouldn''t produce an error if you tried
to add something that was not text. Could you provide some code from your
application?
