I have migrated a vb.net program to vb 2005. I am going nuts trying to fix this.
There is a splash screen that fades in and then in the background some sub procedures are taking place.
Here is the original code; This code gives me cross threading errors dealing with the opacity. - Private myDebuglog As DebugLog = ApplicationDebugLog
-
Private FormAlpha As Double = 0
-
Private WithEvents AlphaTimer As New System.Timers.Timer
-
Private WindowsSecurityPrincipal As System.Security.Principal.WindowsPrincipal = New System.Security.Principal.WindowsPrincipal(System.Security.Principal.WindowsIdentity.GetCurrent())
-
Private ntUserName As String
-
Private strt As System.Threading.Thread
-
-
-
Private Sub frmSplash_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
-
' Fill in the user box
-
ntUserName = WindowsSecurityPrincipal.Identity.Name.ToString
-
ntUserName = ntUserName.Replace("ILIOSPARTNERS\", "")
-
Me.txtLogin.Text = ntUserName
-
FormAlpha = 0.0
-
Me.Opacity = FormAlpha
-
AlphaTimer.Enabled = False
-
AlphaTimer.Interval = 10
-
-
AlphaTimer.Enabled = True
-
'strt = New System.Threading.Thread(AddressOf AlphaTimer_Tick(AlphaTimer,)
-
End Sub
-
-
-
-
Public Sub AlphaTimer_Tick(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles AlphaTimer.Elapsed
-
-
If FormAlpha >= 1 Then
-
AlphaTimer.Enabled = False
-
Me.Opacity = 1.0
-
Else
-
Me.Opacity = FormAlpha
-
FormAlpha += 0.05
-
Me.Refresh()
-
End If
-
End Sub
-
-
Public Sub UpdateStatus(ByVal status As String)
-
lblLoadingStatus.Text = status
-
Me.Refresh()
-
End Sub
-
-
-
Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
-
Me.Dispose()
-
Application.Exit()
-
End Sub
---------------------------------------------------------------------------------------------------------------
So I modified the code to like this thinking this would solve the problem but now I get disposed errors.
here is the revised code; - Private myDebuglog As DebugLog = ApplicationDebugLog
-
Private FormAlpha As Double = 0
-
Private WithEvents AlphaTimer As New System.Timers.Timer
-
Private WindowsSecurityPrincipal As System.Security.Principal.WindowsPrincipal = New System.Security.Principal.WindowsPrincipal(System.Security.Principal.WindowsIdentity.GetCurrent())
-
Private ntUserName As String
-
Private strt As System.Threading.Thread
-
-
Private Sub frmSplash_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
-
strt = New System.Threading.Thread(AddressOf updateValues)
-
strt.Start()
-
' Fill in the user box
-
ntUserName = WindowsSecurityPrincipal.Identity.Name.ToString
-
ntUserName = ntUserName.Replace("ILIOSPARTNERS\", "")
-
Me.txtLogin.Text = ntUserName
-
FormAlpha = 0.0
-
Me.Opacity = FormAlpha
-
AlphaTimer.Enabled = False
-
AlphaTimer.Interval = 10
-
-
AlphaTimer.Enabled = True
-
'strt = New System.Threading.Thread(AddressOf AlphaTimer_Tick(AlphaTimer,)
-
End Sub
-
-
-
-
Public Sub AlphaTimer_Tick(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles AlphaTimer.Elapsed
-
updateValues()
-
-
End Sub
-
-
Public Sub updateValues()
-
If FormAlpha >= 1 Then
-
AlphaTimer.Enabled = False
-
changeOpacity()
-
'Me.Opacity = 1.0
-
Else
-
changeOpacity()
-
'Me.Opacity = FormAlpha
-
FormAlpha += 0.05
-
Me.Refresh()
-
End If
-
End Sub
-
-
Public Sub UpdateStatus(ByVal status As String)
-
lblLoadingStatus.Text = status
-
Me.Refresh()
-
End Sub
-
-
-
Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
-
Me.Dispose()
-
Application.Exit()
-
End Sub
-
-
Public Sub changeOpacity()
-
If Me.InvokeRequired Then
-
Me.Invoke(New MethodInvoker(AddressOf ChangeOpacity))
-
Else
-
Me.opacity = FormAlpha
-
End If
-
End Sub

Please state the error in full and whether it gives you a line number. Also more info about the platform you are working in might help, OS, .net version etc. Thanks.

Can someone look at this and tell me why, when I call this from my main app,
it displays fine (fades form in and out) but then before my main app
displays, I see other dialog boxes flash monentarily on the screen and this
delays the main app display?
Here is the fade which I compile to a dll and call from my main app:
using System;
using System.Threading;
using System.Timers;

Hi All
I have an odd thing happening with my splash screen form
The splash screen is set in Project properties and in the 'new' event of the
splash form I run some code (before the initialisation) to launch a form

All worked well

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
