Exception When Running App In New Machine
Aug 25, 2009
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 am an end user of a VB based program and our windows 95 based machines are dying of old age. Before getting my boss to agree to my trying out a newer machine I would like to know if there is any chance of getting this program to run.
I know that I need to be able to drive 3 serial (485 / 422/ 232) ports one of which is on an ISA bus and the other 2 are located internally on the motherboard. Another factor in trying to do this is the drivers are missing for the 485 card and I hoped
to be able to locate newer drivers easier.I think the VB code was created under VB3, but we do not have the expertise / tools to be able to disassemble the .exe file.

Here's the situation - I have a vb.net exe compiled for X86 machines using 2 dll's... Because one of the dll's was only provided in 32 bit, and I didn't want to have to deal with 32/64 versions, I forced 32 bit in compile options and everything was fine. Now I have a 64 bit workstation that is throwing an error about the sqlite.dll (error #1 below).
after reading around I am starting to understand a lot of people are having this issue. I tried replacing the dll on the client machine with the 64 bit version of sqlite and that didn't work (error #2). I read somewhere that the 64 bit version requires VC 2010 redistro, but that didn't work. I can't compile this app as a 64 bit because of the other dll is 32 bit.

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.

I have developed a 32-bit VB.NET application that runs fine on 32-bit systems. Some of the folks in engineering, however, are using 64-bit machines, so we have created 32-bit virtual PCs and installed the application on the Virtual PC. When we try to run it, however, the application fails to establish a connection to the SQL server (remote, SQL 2000) for login validation.

The conditions are I don't have administrator privilege I want to see the status of a service in remote machine (server)I use the following code (vb.net with framework 2.0) to see the status
Dim sqlSvc As ServiceController
Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName)
If sqlSvc.Status.ToString.Equals("Running") Then
displayStatus("success", sqlSvc.Status.ToString)
Else
displayStatus("error", sqlSvc.Status.ToString)
End If
When running the code, InvalidOperationException is raised and found out that I need admin right in the server.Can I lookup the status of the service without having admin right in remote machine ?

I just want to write code inside my assembly to detect whether it is running on a "desktop machine", or inside the context of an ASP.NET application. This is crucial guys, (licensing purposes), and I don't want to get fired because I did a mistake.So, please, be direct and if you please give me some code snippet.
EDIT v 2.0: What about using in the assembly:
[assembly: "AspNetHostingPermission (SecurityAction.RequestRefuge, Unrestricted=true)]"
to prevent the execution on the web?

I have some programs written in VB2010 using functions from a DLL. I have compiled and run these programs on a 32bit XP computer and a 32bit Win7 computer and have had no problems accessing the DLL.I have published an installation of these programs and tried running the install on a 64bit Win7 machine and the installation is performed correctly. It installs the programs and copies the required DLL into the same folder. the problem is that whenever I run the software and try to access the DLL I get errors.
The error says something like:
An unhandled exception has occurred in your application. An attempt was made to load a program with an incorrect format. (Exception from HRESULT:0x8007000B)
If I click past it the software runs and all of the forms are loaded properly, but anytime in the software if I try to access the DLL I get the same error.I am declaring functions in the DLL like this:
Public Declare Function OpenDriver Lib "OP815M.DLL" (ByVal handle_Renamed As Integer) As Integer
I have also tried placing the DLL in the system32 directory and also the sysWOW64 directory and that did not help as well.I do recall that hardware drivers need to be properly signed and pass the Microsoft Logo testing. Must I get the DLLs I am using properly signed?
Edit: Also it might be fair to mention that I have used the DLL with another program written in C, which would run in the DOS command line in Windows and it correctly accesses the DLL on a 64bit machine, but just when run from the DOS command line in windows.

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.

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 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'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.

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:
