Hello,
I am stumped on an issue and I can't figure out why it is doing this. My application uses a tab control, which automatically switches to the next tab control at the set interval. When the appropriate slide is showing, it reads the appropriate line of text.
However, it recently and randomly started repeating the last tabpage's and then saying the current tappage instead of just saying the current tabpage. I do not have it coded to do this and it randomly started doing this.
Here is my code:
Auto Slideshow of Tabpages:
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs)
Dim g As Graphics = e.Graphics
Dim _TextBrush As Brush
' Get the item from the collection.
Dim _TabPage As TabPage = TabControl1.TabPages(e.Index)
' Get the real bounds for the tab rectangle.
Dim _TabBounds As Rectangle = TabControl1.GetTabRect(e.Index)
If (e.State = DrawItemState.Selected) Then
' Draw a different background color, and don't paint a focus rectangle.
_TextBrush = New SolidBrush(Color.Red)
g.FillRectangle(Brushes.Gray, e.Bounds)
Else
_TextBrush = New System.Drawing.SolidBrush(e.ForeColor)
e.DrawBackground()
End If
' Use our own font.
Dim _TabFont As New Font("Arial", 10.0, FontStyle.Bold, GraphicsUnit.Pixel)
' Draw string. Center the text.
Dim _StringFlags As New StringFormat()
_StringFlags.Alignment = StringAlignment.Center
_StringFlags.LineAlignment = StringAlignment.Center
g.DrawString(_TabPage.Text, _TabFont, _TextBrush, _TabBounds, New StringFormat(_StringFlags))
End Sub
Private Sub LFI_Panel_Timer_Tick(sender As Object, e As EventArgs) Handles LFI_Panel_Timer.Tick
If TabControl1.SelectedIndex < TabControl1.TabCount - 1 Then
TabControl1.SelectedIndex = TabControl1.SelectedIndex + 1
Else
'Go to the first tab
TabControl1.SelectedIndex = 0
End If
Narration Code:
Private Sub TabPage1_Enter(sender As Object, e As EventArgs) Handles TabPage1.Enter
Task.Run(AddressOf CurrentConditionsVoice)
End Sub
'THE ABOVE IS DONE FOR EACH TAB PAGE ONLY THE ADDRESSOF IS DIFFERENT.

The above code has worked flawlessly. This issue started after I forgot to plugin my speakers or headset and it caused the program to give an AudioException because it couldn't find an audio output. What is going on with the application and how can I fix it?
