SQL Exception Error Running Sample CreateDb?
Sep 26, 2011
I am attempting to run (unaltered) the sample program found in the VS2010 package CreateDb.When running the Create Database intially from the button on Form1 I get a SQL Exception Error diaglog that states: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I was scripting a very basic process manager, with a ListView component, and it was working fine for many days, up until now.Here is the code for getting processes:
Dim Process As New Process()
Dim Count As Integer = 0
ListView1.Items.Clear()[code].....
The line of code where I put "*WIN32 EXCEPTION LINE* keeps running into an error(Win32 Exception was unhandled; Access is denied). Here is the full error description:
System.ComponentModel.Win32Exception was unhandled
ErrorCode=-2147467259
Message=Access is denied[code]....
As I said before, this had been working for several days, up until now.

We have a VB.NET applciation that is run from a mapped network drive. This works fine on all PCs expect those with Windows 7, on those we get the following: "application generated an exception that cannot be handled" System.Security.SecurityException was unhandled If the application folder is copied locally and run from there it works fine. I assume it is related to Windows 7 netowrk security but not sure how to work around it.

I'm making a program from witch one could run an application with different credentials.I can compile the program successfully, but when I press the button to run the program I get the following error: Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.The system cannot find the specified file.The code behind the button is as follows:
Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process()
myProcess.StartInfo.FileName = "c:
un.bat /user:kreathyr c:getlogin.exe"
myProcess.Start()
Getlogin.exe does nothing but show the logged in username and run.bat utilizes the runas command.

I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...

I just finished coding a small app which access the Outlook 2007 Inbox. On my dev machine, it works OK. I created a new machine in VMWare using WinXP, Dot.Net 3.5 and Office 2007 installed and Outlook configured to my GMail account.I copied the BIN folder of my project to the new machine and ran the app and it runs OK until it scans all emails in the Inbox. This is where I get the exception:[code]When JIT debugging is enabled, any unhandled exceptionwill be sent to the JIT debugger registered on the computerrather than be handled by this dialog box.Can anyone suggest why my code can not see the Outlook 12 assembly? Do I have to create an installer file for my app before copying it to the test machine?

I started out with a console application but half way I switched to windows form in the application properties. Does that have something to do with it? I do this because I don't want to show the console. My application takes about 57 miliseconds to run. Maybe it's too fast for the clr profiler ?

The code below runs on the click of a button to create a table in a SQL Server database and then runs a stored procedure to update the table. The whole procedure runs and works fine the first time However when I click the same button again and run it immediately after I get a Object reference not set to an instance of an object. exception. Not sure why this is and what to do in this situation.

I am doing automation testing of a web application using selenium. While running automation testing of web application you encounter application errors. Is there any way to detect those exceptions. Specially exceptions that are on the page which causes the page to hang up as it is not finding the element it is looking for or page stays on the same page and waitforpage() function keeps running.

i have this line of code to catch an exception if a letter is inputed, or if it is out of rang as a number, but I have added WHEN to avoid catching numberical data. Now how can I use an exception error to use it before my case statement in order to avoid running the code twice, cause once the case codes has been through it will run a clear txtbox which is already taken care by the try catch, don`t if thats clear for you but i understand it. here is the code in parts...
Try
'Integer Levels: intLvls is egual to the assigned text box, the first one from
'the top, this line of code allow the user input to be captured into a variable.

I am using VB.NET 2005 to create a Windows forms application. I have a procedure named SendMail that creates an instance of Outlook.Application, to send an email from my application. I found the code on this forum, I think.The procedure works fine, but I can't use error handling with it.I call the procedure from a button click event. I put the procedure call in a try/catch block, and the application won't build, with the following error.

Using MS Visual Studio 2010 Express, when trying to debug, the build finishes and the following error below appears. It doesn't seem to effect the running of the program.
The error is:

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

I have installed a debug version of my program at a customer for him to test it and therefore have copied the debug .exe and .pdb file instead the release version. So when an error occurs the exception window comes up and I can see in which file and code line the error appeared.
Unfortunately, when an error occures, the Microsoft error report windows comes up. I deactivated error reporting in the control panel, but still it comes up.
