Persistent "Dispose" Error In VB2008
Jan 9, 2011
I have an error in the beginning of a program I have converted from VB2002 to 2008, and I can't seem to find a way out of it. The error message is:Error2'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.C:Documents and SettingsAdministratorDesktopBack UpExpendable VS8 copiesClick Counter VS8Click Counter VS8frmSecond.Designer.vb729Click Counter VS8
The offending code seems to be the word "Dispose" after the words "Overrides Sub".

Why does everyone say in forums that it is Rolling back in the dispose? Where does it rollback?

I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.
Dim oEmail As New System.Net.Mail.MailMessage()
oEmail.From = New MailAddress(strSender)
oEmail.To.Add(strRecipient)
oEmail.Subject = strSubject

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

The exact error I am getting in Visual Studio 2012 is:
error BC30456: 'Dispose' is not a member of 'System.Net.Mail.SmtpClient'.
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Port = 25
[code]....
This should be an obvious error. You would think I was using .net framework 3.5 or lower as Dispose() was only added as a member to SmtpClient in .net 4.0. However, I am using 4.0!In the website property pages it states 4.0. Is there somewhere else that I need to set as 4.0?

I am trying a example codes of animated graphics. I rewrote all the code and I found an error which doesn't happen on the example code(I run the example project)
error: 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.
when I double clicked the error, I got this in Form1.Designer.vb:
'Form overrides dispose to clean up the component list.

I have a converted VB6 App that would draw irregular shapes on a PictureBox when I click on a button, and these irregular shapes would persist until I either close the App or erased the PictureBox to start the display anew.I converted my App to VB.Net to do the same, i.e. draw on a PictureBox again, but the drawn lines appear briefly and then, at the end of the drawing process, when my App returns control to the Operating System in wait for another event, the graphics disappear as if erased by the App (which I don't do of course).I have created a Graphics Object associated to my Picture Box as:
Dim CurrGraphics as System.Drawing.Graphics
CurrGraphics = PictureOut.CreateGraphics
I then use the DrawPolygon and DrawLine methods to add the irregular shapes I want:
CurrGraphics.DrawPolygon(CurrPen, Pts)
CurrGraphics.DrawLine(CurrPen, Pts(I).X, Pts(I).Y, Pts(I+1).X, Pts(I+1).Y)
where CurrPen is a defined Pen, and Pts is the Points() array with the coordinates of the displayed shape. Several dozens irregular shapes are drawn and then the subroutine stops, and returns to waiting for another request from the user.What could be the prime reason why graphics do not persist in a PictureBox, and are erased immediately after they are created ?
PS: I do not use the PainEvent of the PictureBox PictureOut, as in the example given in the VB documentation (below), as the display process is initiated by clicking on a button, and I cannot relate how to transfer control to the PaintEvent as below:
Private Sub Form1_Paint(sender As Object, pe As PaintEventArgs) Handles _
MyBase.Paint
' Declares the Graphics object and sets it to the Graphics object

I am building a program which offers solutions to the travelling salesman problem (finding shortest tour between a set of cities while visiting each only once).
My program loads a bitmap image of a map into a picture box. From there, graphics which point out the cities as well as tour paths are drawn onto the map. My problem is that when the option to plot ALL cities is enacted, the user may choose to pinpoint a specific city with a separate control. When the user erases that pinpoint via an invalidation routine, though, it erases all graphics beneath it, which is undesirable. How can I make my tour graphics and city plots semi-permanent by drawing them directly on the image? I tried drawing them on a separate bitmap, but it 'covered up' the map image.

I have an application that has two states based on the value of a Boolean variable: a read_only=true state and read_only=false state. The value of this state is stored in an external settings file. My application has a feature called deploy that generates a copy of itself in the same folder with the read_only=true state. But, the read_only variable value is stored in an external file so now both files will be in the read_only=true state. What I want to do is make one of them(the original one) always be read_only = false and the other read_only=true

I was wondering if it is possible to have persistent changes to resources in an executable. I am using VB 2010. I don't know how to be much clearer than that but I will try.
> User opens program and picks 'File A'
> 'File A' is now copied into the executable, thus storing it forever (or until deletion of .exe
> .exe is now slightly larger because 'File A' is inside the program
> User can extract or delete 'File A'

point me to the best way to store persistant objects ( of my own class) in a vb application? I am putting together a simple family recipe application and have created a food item class. I would like to store the instances ( food items) indefinately so that they are there each time I start the program complete with all properties and meethods

You know how using My.Settings.something to store persistent data is done only for user settings and not application settings. This information is stored in the registry on the local user section.My problem here is that even if it is in the same machine, when a user changes some setting it is not reflected on other users. This is desirable for some of them but there are a few I would like to keep for all users.Is there a way to do it with the settings? Do I need to write to the registry in the machine section? or do you just recomend I create a configuration file?

I'm trying to create a version of the game Spill and Spell. I'm having problems with a click event for Labels that is supposed to exchange the .Text value stored from the previous mouse click with the current .Text value on the new Label clicked. The labels are initialized and stored in an array on the form load.
What's happening is that the values are remaining persistent to the label being clicked.
Desired Results (example):
User clicks on lblDice1 (sender), tempLetter is set to mouseLetter.CurrentLetter, mouseLetter.CurrentLetter is set to lblDice1.Text (sender.text), lblDice1.Text is set to tempLetter. (this part works)
User clicks on lblDice2 (sender), tempLetter is set to mouseLetter.CurrentLetter (s/b initial .Text value from lblDice1 above), mouseLetter.CurrentLetter is set to lblDice2.Text (sender.text), lblDice2.Text is set to tempLetter.
What's Happening:
The tempLetter and CurrentLetter values are remaining persistent to the Label being clicked on. Ie: lblDice1 click will only display the original text associated. If I click Dice1 then Dice2 and then Dice1 again, the original Dice1 text is displayed (same for Dice2).
This is a lot easier to see. All of the controls with the exception of a button ("btnStart") are defined in the code below. Click the Start button to show values in the DiceLabels grid.
The area that's the problem is Public Sub DiceLabel_Click
(this is a work in progress...)

I have a VB2002 program that works. When I run it in VB2008, it updates, and runs and debugs until I shut down. When I try to start it up again from the updated SLN, or try to run the .exe in the BIN folder, I get the message "This application has failed to start because the application configuration is incorrect.
I checked the error logs and it says there is a syntax error in the first line of the vhost.manifest file in the BIN folder. The first line is the xml declaration and it includes the parameter standalone = "yes".
When I put the error message into Google I only get references to Visual C++ compiled programs running on machines without the C++ redistributable dll. That doesn't seem to apply here at all, since I have the VB 2008 express edition installed on this

In one of my forms witch I imported from VB2008 there are all properties saved in the *.resx file. One Property, of the Type System.Windows.Forms.Keys, can contain the Value 'Ctrl+F1' witch compiles fine in VB2008, but not in VB2010. To reproduce, simply add the following to any resx file:
<data name="cmdFenster.ShortcutKeys" type="System.Windows.Forms.Keys, System.Windows.Forms">
<value>Ctrl+F1</value>
</data>
It will compile fine with VB2008, but not with VB2010. Notice: The VB2010 also generates this Code in the resx file

I am having fun working with System.Threading.Tasks. Many of the code samples I see, however, look something like so:
Dim lcTask = Task.Factory.StartNew(Sub() DoSomeWork())
Dim lcTaskLong = Task.Factory.StartNew(Sub() DoSomeWork(), TaskCreationOptions.LongRunning)
Task.WaitAll(lcTask, lcTaskLong)
That's the extent of the sample.Tasks implement IDisposable, so obviously I'm supposed to dispose of them, but what if I just want to "Fire and Forget"?If I don't dispose, will I leak threads/handles/memory/karma?Am I using tasks "wrong"? (Should just use a delegate and leave tasks alone?)
Can I dispose in a "ContinueWith()"? (That seems like playing Russian Roulette.)[URL]..
