I am writing a app in VB and get errors with inserting or deleteing records. I can do a try catch in by app, but I would like to know how to make the cryptic error messages that I get back from my tableadapter queries into messages that make sense to the end user.
Ex. ERROR [23000] [Microsoft][ODBC SQL Server Driver][SQL Server]The DELETE statement conflicted with the REFERENCE constraint "FK_License_Vendor". The conflict occurred in database "AssetsSQL", table "dbo.License", column 'VendorID'. ERROR [01000] [Microsoft][ODBC
I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
So when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.

I'm new to visual basic 2008 and have worked on this question for quite a bit before deciding to come to this website and asking for someone to walk me through it."Write a program that requests an amount of money as input and displays the names of all liquids for which a gallon could be purchased with that amount of money. The information in the (table 6.2) should be read from a file. As an example if the user has $2.35, then the following should be displayed in the list box: "You can purchase one gallon of any of the following liquids:Bleach Milk".[code]

How can I make it so that when my Webbrowser returns an error - such as 404 or 407, it shows a web page of my choice like a webpage designed by me instead of the IE version?
I am trying to deploy a ClickOnce app. It had worked previously when the server was just sitting with .Net 2.0 installed (no SP). Recently the server had 3.5SP1 installed on it and now ClickOnce is failing with the error:Value does not fall within the expected range inside System.Deployment.
Here is the information posted on the MSDN forums (answers there are generally hit or miss for me) with the call stack:It was in VS 2005 w/SP1 and I tried changing the path I publish to, changing the installation URL, changing the assembly name, manually controlling versions, running mage -cc, manually removing all application data in %userprofile%AppDataLocalApps and even changing deployment servers completely but still get the same error:
The whole code here has to be used as a search engine. I need to build strings and then, convert them into queries. I had already done everything with linq-to-sql. But it seems impossible to convert a string into a linq querry. However, I found on stackoverflow a kind of solution, but I've never been able to use it : String.ToLinqQuery(). It's just not known by visual studio, and I can't find any documentation about it.
I am using VB.NET Framework 3.5 . I have a very complicated program with over 40 forms and 100s of lines of coding. Earlier today, this program worked perfectly. I decided to change the Assembly Name from APA to Salamander. I do not get any errors and things seem to be going fine. Upon the next debug, the splash screen loads fine. (I am using a timer to proceed to the main form, not the inbuilt splash screen setting as I found it to be more reliable). However, when the main form loads, none of the pictures (resources) load and it exits itself immediately yet no errors appear at all. I think it might be to do with the .resources file but I really don't know. As I only started Visual Basic less than two months ago I'm not sure what all the files other than .vb files actually are.I really don't want to have to completely rebuild the program as my release date is in five days and as I am still at school I don't have time to complete it on top of homework. I have tried changing the assembly name back to APA again but it still does not work. I am completely stumped.
I'm converting some C# code to VB.Net, as it's a language I know better, I've got some code that I can't figure out...
Dim mybtn As New ImageButton() mybtn.ImageUrl = _imgUrl Select Case _buttonType Case ButtonType.Backpage
[CODE]...........
This is giving 2 errors:
Me.btnBackpage_Click = Delegate 'System.Web.UI.WebControls.CommandEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.
And
mybtn.Command = 'Public Event Command(sender As Object, e As System.Web.UI.WebControls.CommandEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
When ever I use a Shockwave Flash Object in one of my Forms, it always says this It might be to do with some Add-On packs which I downloaded ages ago, but I have no idea. I have tried uninstalling and re-installing Flash, and the same for Visual Basic and all of it's components.
I'm converting an existing VB6 command line app to VB.net as need a bug or 2 fixed. It uses 3 x Crystal Reports 9 libraries. The only errors I have now are related to CR9 (dll) code, but don't have CR9 on the VSE machine, & dont have VSE on the CR9 machine. We also have a CR11 version of this. The fellow who created them has left & we dont have VB6, he used his own.I can't seem to copy the 3 x CR9 dll's to the VSE machine to get rid of the errors, says the dll access is denied, source file may be in use.I can't install VSE on the CR9 machine so have to create/build it on the VSE machine & copy exe to the CR9 machine.

When I am Connecting a website through remote machine, The Website showing the run-time error
Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.
But i want to display entire site in my website, and one more thing i am using Ajax controls in website, they are CalenderExtender control.[code]...
1. I can check a DataSet for errors with DataSet.HasErrors and I wonder how to check the same thing for a DataGridView.
2. Coming from MS Access I am not used to batch editing a dataset via a datagridview for instance. Think of a multi user Windows forms application / SQL Server setup. So I wonder if it's ok to just save the data after a row has changed, edited or deleted and not wait till all modification are done and then do a batch update?
