Visual Basic .Net List BoxI 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 Show the newsgroup the code you have & we'll see where you are going wrong
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? -Jason Show quoteHide quote "Hank1234" <Hank1***@discussions.microsoft.com> wrote in message news:0042E09A-9120-4134-8B22-2DB72A7FC2D4@microsoft.com... >I am having a problem with a list box on a form.

If I think
of anything, I'll post back. I'm not sure if any kind of system font changes or anything would affect it or not. Try doing ListBox1.Items.Add(New String("Hello")) That will most likely come up with the same result, but it's worth a shot. Sorry I can't be of more help on this one. -Jason Show quoteHide quote "Hank1234" <Hank1***@discussions.microsoft.com> wrote in message news:981D4CDC-2A8D-44FA-B106-2F4049BBAFD7@microsoft.com... > Here is the code I was testing with. > > Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As > System.EventArgs) Handles Button1.Click > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > ListBox1.Items.Add("HELLO") > End Sub > > "OpticTygre" wrote: > >> Are you positive you're adding type "text" to it?

Thats the only thing I can find that produces those results (Scrollbars showing, but no text) MP I have tried the "ListBox1.Items.Add(New String("Hello"))" code but it
produces the same result of no text but the scroll bars show up. I have also checked the properties of the list box and the DrawMode is set to "Normal". Even if I manually change the items (before runtime) it does the same thing. Any other ideas?

and it is fairly new to the enviroment. I will guess that this is the problem and will see why we do not allready have this patch. Thanks again. Show quoteHide quote "Herfried K.

will keep the same default name, so, you won't need to alter your code. Does that make any difference? McAfee lets viruses through.. Symantec Antivirus 9.0 Corporate Edition is far better!! The patch has solved the problem, thanks again.
