[02/03] Weird Problem with Visibility

[JohnRChick]

Hey. Ok I have this label on my forum that is my default set to be not visible. When the forum loads my program executes some code to check for new software updates. If there are any, it makes the label visible and allows the user to click on it and download the updates. This automatically opens a new forum called FrmUpdate. The thing is, this forum looks all greyed out and eventually I run into an error where it says that "an external component has thrown an exception". Now if I set the label to be by default visible in the properties, then I don't have this problem. I don't understand why this is happening, because either way I am eventually making the label visible. It's just weird that the default visible is screwing it up.. Any ideas why?

Thanks
John

Have you tried stepping through the code from the time you click on the label? That might show you where the problem is.

Sounds like the reason visibility is messing up your code is that you have an if statement based on the visibility of the label somewhere. As for the solution to that, I couldn't guess at that without seeing some code...

I'm not to sure how to use the debugging mode. And I dont have any if statements that depend on visibility. Here's the code for the label:

If (labelInformationSystem.BackColor.Equals(Color.Yellow)) Then
            If fu Is Nothing Then
                fu = New FormUpdate
            End If
            fu.ShowDialog()
        End If

I know that that part deals with color, but either way when it comes to determining the color of the label, the label has already been turned visible. I have code that makes it visible after a certain amount of time. The real problem just simply steps from If I set it to visible or invisible when i'm in regular design mode. Any ideas?

It sounds like there's some code somewhere in your program that isn't doing what you want... without a more detailed look at the program, it is hard to know where to begin...

I suggest you have a quick look at jmcilhinney's profile with all the tutorials... I lifted this article from there. It should get you going with debugging, which is learning to fish as opposed to being fed a fish I keep jmcilhinney's profile on tap in case I run into problems... Might I suggest the same?
