[RESOLVED] Splash Screen "Coding to make it Optional"

I'm writing a small program and it uses a Splash screen. This program will be accessible on various PC's. I was attempting to make it optional for users with powerful PC's. The following code is what I have and it yields an runtime error. This option is a ToolStripMenuItem. Is it possible to save this setting?

VB.NET Code:

If My.Application.SplashScreen.Enabled = True Then
            Me.EnableSpToolStripMenuItem.Checked = False
            My.Application.SplashScreen.Enabled = False
        Else
            Me.EnableSpToolStripMenuItem.Checked = True
            My.Application.SplashScreen.Enabled = True  
        End If

yeah! it is! you can save the settings in registry. here is the sample code, you can edit it according to your need:

Add this on the top:

vb Code:

Dim YourApplicationName as String = "Your Application Name"
Dim SplashScreenEnable as Boolean = True

How To Save:

vb Code:

Private Sub SaveSettings(ByVal showsplashscreen as Boolean)
        Dim ParentKey, Key As Microsoft.Win32.RegistryKey
        Dim SubKey As String
 
        ParentKey = Microsoft.Win32.Registry.CurrentUser
        SubKey = "Software\"+YourApplicationName
 
        Try
            'Open the registry key.
            Key = ParentKey.OpenSubKey(SubKey, True)
            If Key Is Nothing Then 'if the key doesn't exist.
                Key = ParentKey.CreateSubKey(SubKey)
            End If
 
            'Set the values.
            Key.SetValue("ShowSplashScreen", showsplashscreen)
 
            MsgBox("Settings Saved.", MsgBoxStyle.Information)
        Catch e As Exception
            MsgBox("Cannot save the settings.\n\nError occurs in WriteRegistry" & e.Message, MsgBoxStyle.Information)
        End Try
    End Sub

How To Load:

vb Code:

Private Sub LoadSettings()
        Dim ParentKey, Key As Microsoft.Win32.RegistryKey
        Dim SubKey As String
 
        ParentKey = Microsoft.Win32.Registry.CurrentUser
        SubKey = "Software\"+YourApplicationName
 
        Try
            'Open the registry key.
            Key = ParentKey.OpenSubKey(SubKey, True)
            If Key Is Nothing Then 'if the key doesn't exist
                Exit Sub
            End If
 
            'Get the value.
            SplashScreenEnable = Key.GetValue("ShowSplashScreen")
 
            ProfileLoaded = True
        Catch e As Exception
            'Console.WriteLine("Error occurs in ReadRegistry" & e.Message)
        End Try
    End Sub

SplashScreenEnable will be the value (True or False)

Call the LoadSettings function and you'll get the saved value.

Rate my post if it helps you!

Thank you very much. This seems very promising, but I do not know where to place this code to test it. I have a main form and a ApplicationEvents.vb file.

Woah.... stop....
Right-click the project and pull up it's properties. Go to the Settings Section and add a User level setting, call it ShowSplash, or whatever and set it to type boolean. The Default value is "True"

Now.... in code Use the My keyword.... My.Settings.ShowSplash.... you get it and set it jsut like any property and it automatically saves.

NOTE - this is for 2005... you didn't specify what version of VS you are using, so if it isn't 2005, this won't work.

-tg

just put this in the man form file..

Ok. What does the ProfileLoaded boolean variable do? It's not declared.

oohh remove that variable.. i forget to remove that variable...

ok. however, it didn't work. I think I just didn't integrate it correctly. For instance, used

vb Code:

my.application.info.assemblyname

in place of using;

vb Code:

Dim YourApplicationName as String = "Your Application Name"

And the SplashScreenEnable variable was made global.

The following is how I am trying to use the code you provided to helped me;

In the Main Form | Menu | Item:

vb Code:

Private Sub mnuItemEnableSplashScreen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuItemEnableSplashScreen.Click
        If Me.mnuItemEnableSplashScreen.Checked Then
            Me.mnuItemEnableSplashScreen.Checked = False
        Else
            Me.mnuItemEnableSplashScreen.Checked = True
        End If
        My.Settings.SplashScreenEnable = Me.mnuItemEnableSplashScreen.Checked
        SaveSettings(My.Settings.SplashScreenEnable)
    End Sub

In the Main form's Load sub:

vb Code:

LoadSettings()

according to your script, change the loadsettings subto this:

Code:

---

Private Sub LoadSettings()
        Dim ParentKey, Key As Microsoft.Win32.RegistryKey
        Dim SubKey As String
        ParentKey = Microsoft.Win32.Registry.CurrentUser
        SubKey = "Software\"+my.application.info.assemblyname

        Try
            'Open the registry key.
            Key = ParentKey.OpenSubKey(SubKey, True)
            If Key Is Nothing Then 'if the key doesn't exist
                Exit Sub
            End If

            'Get the value.
            My.Settings.SplashScreenEnable = Key.GetValue("ShowSplashScreen")

        Catch e As Exception
            'Console.WriteLine("Error occurs in ReadRegistry" & e.Message)
        End Try
    End Sub

---

Ugh.... pick a spot. EITHER the REGISTRY... OR in application Settings.... don't try to mix the two... all the code above does is pull it out of the registry and stuff it into My.Settings..... still doesn't do any good... still need the value out of My.Settings in order to use it... so what's the point?

use this code like you have it:

Code:

---

      Private Sub mnuItemEnableSplashScreen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuItemEnableSplashScreen.Click
              If Me.mnuItemEnableSplashScreen.Checked Then
                  Me.mnuItemEnableSplashScreen.Checked = False
              Else
                  Me.mnuItemEnableSplashScreen.Checked = True
              End If
              My.Settings.SplashScreenEnable = Me.mnuItemEnableSplashScreen.Checked
              SaveSettings(My.Settings.SplashScreenEnable)
          End Sub

---

In the form load of the main form:

Code:

---

If my.Settings.ShowSplash Then
  'Load your splash screen and show it
End If

---

No complicated registry.

I'm sorry, but you lost me.
"according to my script..."

Is this an answer to my question or are you attempting to verify what my code should look like after the changes I said I made?

The sub look actually like that, but my question remains...

Myke

look,.... starting from the beginning:

Code:

---

' This will save your settings
Private Sub SaveSettings(ByVal showsplashscreen as Boolean)
        Dim ParentKey, Key As Microsoft.Win32.RegistryKey
        Dim SubKey As String

        ParentKey = Microsoft.Win32.Registry.CurrentUser
        SubKey = "Software\"+my.application.info.assemblyname

        Try
            'Open the registry key.
            Key = ParentKey.OpenSubKey(SubKey, True)
            If Key Is Nothing Then 'if the key doesn't exist.
                Key = ParentKey.CreateSubKey(SubKey)
            End If

            'Set the values.
            Key.SetValue("ShowSplashScreen", showsplashscreen)

            MsgBox("Settings Saved.", MsgBoxStyle.Information)
        Catch e As Exception
            MsgBox("Cannot save the settings.\n\nError occurs in WriteRegistry" & e.Message, MsgBoxStyle.Information)
        End Try
End Sub

' Now this will load
Private Sub LoadSettings()
        Dim ParentKey, Key As Microsoft.Win32.RegistryKey
        Dim SubKey As String
        ParentKey = Microsoft.Win32.Registry.CurrentUser
        SubKey = "Software\"+my.application.info.assemblyname

        Try
            'Open the registry key.
            Key = ParentKey.OpenSubKey(SubKey, True)
            If Key Is Nothing Then 'if the key doesn't exist
                Exit Sub
            End If

            'Get the value.
            My.Settings.SplashScreenEnable = Key.GetValue("ShowSplashScreen")

        Catch e As Exception
            'Console.WriteLine("Error occurs in ReadRegistry" & e.Message)
        End Try
End Sub

' now, your menu item click event:
Private Sub mnuItemEnableSplashScreen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuItemEnableSplashScreen.Click
        If Me.mnuItemEnableSplashScreen.Checked Then
            Me.mnuItemEnableSplashScreen.Checked = False
        Else
            Me.mnuItemEnableSplashScreen.Checked = True
        End If
        My.Settings.SplashScreenEnable = Me.mnuItemEnableSplashScreen.Checked
        SaveSettings(Me.mnuItemEnableSplashScreen.Checked)
End Sub

' on form load
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        LoadSettings()
       
        If My.Settings.SplashScreenEnable Then
            ' Show Splash Code goes here!
        End If
End Sub

---

this is what you want to save your settings... i'm 100% sure that this will work!

and never forget to rate! [;)]

OK, I did all that except for the If statement. However, techgnome offered a more desired approach which didn't change my original coding and it works.

I will be creating another larger appliaction soon and will definitely apply your code to it's similar feature.

Thanks a million extreme.aly & techgnome. Having support from guys like you would definitely motivate to me to give support back once I'm no longer a beginner...

well few days back, i was also a beginner but VBForum really help me alot in learning vb.net!
