Post subject:  Tab Order
I am trying to set up a Tab Order for a form I am designing for class. When I open the tab order stuff it starts with 0 then the sub categories are 0.1 and up then 1, 1.0 and up, etc.

Which determines the priority order? Would 0 get the priority or it is high to low?

Typically, low to high.

now... if I may ask a follow up question:

I have a field that is entered with an integer... and when you check a radio button it sets a second text box (hidden) with a value.

Now when I click a button it unhides a DiplayText, which I am trying to populate as follows:
Code:
DisplayText.Text = Val(TimeText.Text) + Val(OffsetBox.Text)


The issue I am encountering is that in order to actually show any text in the box I need to manually place my cursor in the window and press any key. Once I do this it displays as expected.

Isn't there a way to automatically display the data without the need to go into the field that way?

Depends on the language. If you're doing this in some flavor of VB, Application.DoEvents might be what you need. If it's not related to VB, you'll need someone else's advice cuz that's the only language I'm currently familiar enough with to offer assistance.

I think you need to move the code that sets the text to within the event callback that happens when you click the radio button.

If this doesn't help, you could paste all your code within a [spoiler ][code ][/code ][/spoiler ] and I could probably help you better.

        ' Displays the MST/PDT display and sets the MST timezone

        ' Displays the CST/MDT display and sets the CST timezone

        PicBox.Image = My.Resources.ChicagoClock
        OffsetBox.Text = Val(6)
    End Sub

    Private Sub PlusFiveRadio_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlusFiveRadio.CheckedChanged
        ' Displays the EST/CDT display and sets the EST timezone

        PicBox.Image = My.Resources.BostonClock
        OffsetBox.Text = Val(5)
    End Sub

    Private Sub PlusFourRadio_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlusFourRadio.CheckedChanged
        ' Displays the EDT display and sets the EDT timezone

        PicBox.Image = My.Resources.globe
        OffsetBox.Text = Val(4)

    End Sub

    Private Sub DisplayText_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DisplayText.TextChanged
        ' Displays the GMT conversion of the initial text based on the selected radio button

        [b]DisplayText.Text = Val(TimeText.Text) + Val(OffsetBox.Text)[/b]

    End Sub
End Class


The bolded part is what is not refreshing until I enter the field and press a key.

Other than this automatic update, the only other thing I want to figure out is how to use the same form to display a xxx time to UTC conversion. But I will get to that later

Interesting. I'd have gone with a single event for changing the value of the radio button group, with a switch statement to test the value of the group and set the text accordingly. Using separate events for each button is an approach I wouldn't have come up with.

In response to the problem you're actually having ... the only place I see in your code in which the value of DisplayText.Text gets changed is within the event that's triggered by the change to said value. I recommend altering the event to be triggered when the value of OffsetBox.Text is changed, since that's what will be modified each time a radio button is clicked.

I'm not sure why that behavior occurs. I created a small form with a textbox and a button. Textbox was set with Text of 1 and Visible = False. I set an event to make the textbox Visible the same way you did it, and it works without having to click in there. We're still using Visual Studio 2005 at work though and it doesn't seem to have that Me.DisplayText.Refresh() method.

No weird defaults as far as fonts go?

I think the issue is that Me.DisplayText.Refresh() does not cause DisplayText_TextChanged() to happen.

You should put this code:


DisplayText.Text = Val(TimeText.Text) + Val(OffsetBox.Text)

in DisplayButton_Click where Me.DisplayText.Refresh() is.
