Text not visible in ListBox

[schaf]

Hi NG !
I have an application which writes information for the user in a
ListBox. This works very good on my computer and also on other
computers. But there are some computers on which the text (Welcome text
after start the application) in the ListBox is not visible. If i do
some actions in the application on this computer, all text would be
shown. But why not the welcome text ? I do a refresh after writting the
text in the ListBox. What could it be ?

Thanks
regards
Marcel

Hard to tell without knowing more. Is your welcome text conditional on
anything? Is there a race condition somewhere? What event are you using
to write your welcome text?

Hi Barry

I add the text as item to the ListBox and do that in the constructor of
the form. In the Activated event I always do a refresh.
First I thought that it could be because i do it in the constructor,
but if that would be a problem, it would be one on all computers. ???

Hi ,

I add the text as item to the ListBox and do that in the constructor of
the form.

Just make sure it's after the call to initializecomponent

In the Activated event I always do a refresh.

You do not need to do this. unless you have something else going around.

Most probably. You could move it to the OnLoad event but I don't think it
will be different at all.

I did it after the call of InitializeComponent

In the Activated event I always do a refresh.

Thanks, I removed it.

Unfortunately it didn't help. The texts are not shown on this computer.

Thanks
