VS 2008 - Use GoTo - Microsoft Seem To Use It A Fair Bit In The Internal .NET Framework Code
Sep 28, 2009
I've seen a few people on here saying that you shouldnt use GoTo in VB.NET and to be honest I've tended to agree as I have never needed to use it and there is always another way of doing something without using it. However, I'm just wondering what is so bad about it? I actually noticed that Microsoft seem to use it a fair bit in the internal .NET framework code, which is what makes me wonder why people are so against it.

is this even necessary in VS2010 & .NET 4.0? I've been trying to take advantage of the new Windows 7 taskbar interfaces like the Jump List. The MSDN documentation/tutorial instructs me to include a System.Windows.Shell, but apparently Shell isn't a member of System.Windows. I downloaded the API code pack, but I am unsure of what to do with it. The instructions say to open the main solution file and build it:QuoteTo build the library (except the DirectX related features) in Visual Studio 2008, please extract the contents of the �WindowsAPICodePack.zip� file in a new folder and build the included �WindowsAPICodePack.sln� file.And so I did that, but that is the extent of the instructions. I thought maybe it was a Visual Studio extension, so I tried accessing Shell again to no avail. Do I need to add each of the respective namespaces' projects to the target solution to use the API Code pack?

I have a for each item in listbox:
try
'code goes here
catch ex as exception
end try
next
now, in my code, i also have if ex = certain error. i'd like it to go back to the top of the try. reason for not letting it do its thing is, i am wanting it to retry it, under the same item. So, is there a way to goto a portion of the code.

I realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3
Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.

i was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?

Is it possible to manually download the Microsoft Framework 3.5 or 4.0 ? That would be useful in order to have it during installation of a program . I know that when installing a VB .NET program , it asks to connect and download it , if the PC does not have it already . The problem is that some people have a very slow connection speed or don't even have any connection . Therefore it would be useful to have that installation kit in order to supply it along with program itself .

I have a question to ask you. All of the programs that I made always worked perfectly in my PC. But, whenever I test it on another PC, it requires a thing like... Microsoft .NET Framework Version 4. Which is really annoying, cuz that thing installs in 15 minutes. I mean, can I do something about this? Is this common?

It might be funny , but I'll ask anyway : is it allowed to create a program with VS2008 while at the same time it will use the Microsoft framework 4.0 ? I am asking because I use VS2008 while at the same time I have the impression that framework 4.0 is "lighter" than 3.5 .

I am creating a Visual Basic 2008 .net application that will be using the Sync Service for ADO.NET on Windows 7 Ultimate. The back end database is SQL 2008. Below are the basic steps I take when the error occurs
a. Add a Local Database Cache item to my application
b. Use the Configure Data Synchronication wizard for the setup process
c. Click the OK button to accept changes
d. An error message is generated, "The given key was not present in the dictionary".
I have attempted this several times and the error message presists no matter how I vary the options. I have also installed Microsoft Sync Framework 2.0 successfully but the error persists. I also have all the following Dlls referenced in my project:
Microsoft.Synchronization.dll,
Microsoft.Synchronization.Data.dll,
Microsoft.Synchronization.Data.Server.dll,
Microsoft.Synchronization.Data.SqlServer.dll,
Microsoft.Synchronization.Data.SqlServerCe.dll.
I am sure I don't need all of these references but I figured it does not hurt to have them all referenced for now. I have the latest OS service and Visual Studio 2008 service packs.

I am currently working on an existing Windows Forms application (VB.net), and am busy reworking the exception handling mechanism.Currently, a lot of methods in the code are just surrounded with try/catch block that catches a generic exception and then calls a utility method that just shows the user a messagebox informing him of the error, and then logging it.So in a lot of cases no corrective action is taken and the exception is just logged. I know this probably isn't the best way but that's they way we're gonna have to do it for the near future.Anyway, I wanted to do this in a more generic way, so I hooked up Application.ThreadException and AppDomain.UnhandledException.
This seems to work well, except for one inconvenience. Whenever an error gets thrown from the .net runtime itself, or a 3rd party control, the stacktrace begins there where the exception is thrown in the framework-methods or 3rd party methods (obviously!)But it would be handier if I had an easy way of finding out exactly where these exceptions cross the boundary into my code. I would like an easy way of determining (in Application.ThreadException) where in my own code an exception originated. am aware this information is contained in the Exception.StackTrace property, but I would like an easy way to get to this specific information seeing as the stacktrace property is one huge string.

I'm currently making a code that will login to a cisco router, and show the version, then return the version to me. The connection to the cisco router is using telnet, and I'm using Dimac's w3Sockets code to Connect, login, and return data. Reference
But currently I'm having some problems, since the router sometimes need the login typed 2 times, or having a key pressed to update the terminal(telnet),meaning i have to check if it gets logged in or not. But the problem is that using dimac code, i can only wait() and waitFor(), and if it none data comes whilst waiting, it keeps on waiting. Is there away to do like: "if wait fails goto"
I've tryed "on error goto", but since its not a error, but just keeps waiting, that dont work. Also, To locate where it gets stuck I have it write to my textbox everytime it takes a step in the code, but its like the dimac code overtakes vb.net. ex: If i send some text to a textbox in the same sub as the connect code is, and it gets stuck at a wait, it dont even write to the textbox, eventhough the textbox.text command was suppose to execute before the wait().
Code:
Private Sub telnet(ByVal port)
TextBox3.Text = TextBox3.Text & Environment.NewLine & "Telnet func Called" 'Cant execute this if it gets stuck at login below. ??

I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).
