When i run the debugging tool for visual basic my computer crashes (Blue screen). it's rather constant with the VB forms, even ones without code at all... Any help on the matter? All the forms were originally built on this computer but don't work any more, they however work fine on other computers so it has to be my computer.

when i attempt to debug a program in visual basic studio 08 the black screen dissapears immediatly and i cannot read anything that appears. not sure if it is an option or a bug, but it makes the system relatively useless.
View 4 RepliesUsing this code, before I added the funky "abort" button code - stopping it using the Stop Debugging button in the IDE blue screened my computer every time, PROCESS_HAS_LOCKED_PAGES - Anyone care to try it ? Win7 Ultimate , VS2010 SP1. This machine has never blue screened since it was built. Code is by no means exotic in any way.

I was attempting to clean up my serial port example that is in the code bank. I had decided to use a modem, thinking that a lot of computers still had them. By using the loopback feature of the modem I am able to simulate / emulate various features of the serial port.All was going well, and then I got a Blue Screen with this error after running for 10 minutes or so:DRIVER_IRQL_NOT_LESS_OR_EQUALSTOP 0x000000d1 etc.I then went back to using my GPS receiver, which sends messages constantly to a serial port. This test ran for several hours(4). It received messages correctly during the entire test.I then created a new, not as complex, version and it also receives the Blue Screen. I have made sure that the modem drivers are up to date, searched for the error, etc. My gut is telling me that it is the modem driver. I have attached the project. This is the scaled back version, but it uses the same functionality.
View 7 RepliesI am developing a simple application in VB10 that uses ADO.net to store data in an Access database, and gets input via a serial port RS232. It works well, but is not fully debugged. Unfortunately, a problem has recently started where as soon as i close the program I get a blue screen. Makes it hard to debug. The solution does not even have to have run; it just has to have been loaded and then exit VB10. The blue screen aslo happens to most of the other example solutions that I have downloaded.
Questions:
1)How do you capture the STOP error codes (probably stupid question)?
2) Is there an easy solution that rings a bell? My IT support is trying but not getting anywhere. Have to believe it is hardware related, but the hard drive checks out with testing.
I was debugging my application when suddenly the computer crashed(blue screen).

I was trying to install a program and it install fine but when i went to run i clicked the icon and i got a blue screen and it rebooted, i found out from the program site that its caused by framework.net, i need to update mine, or fix it i check my add or remove programs and i had 2.0 i went to get 3.0 and it told me that cound not cause of prev version was not upto date.

How is it best to do this?
Simple question that does not seem to be covered: If I use a lot of Debug.WriteLine statements in my code, will they be completely absent in my production version?
I mean: Is the compiler smart enough to not emit any code for those calls? Or would I have to surround them by #if DEBUG..#end if directives?
BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

View 1 RepliesExceptions can have different degrees of impact on a program. For example a program should probably abort if OutOfMemoryException is raised, but it is possible to safely and appropriately handle System.Data.SqlClient.SqlException without putting the program in an unknown state.
I do understand that any exception has the potential to put the program in an unstable state if it is not properly handled. Are there exceptions that should never be handled beyond simply logging and throwing up the stack?

In a nutshell...I have developed a site in ASP.Net and VB.Net which allows a user to create an order and submit it to a SQL Server backend database.
When the order is placed...an xml file is also produced, showing the items that have been ordered...which is then loaded in to a program to update stock quantities.
The code I have is as follows:
Public Sub butSubmitOrder_Click(sender As Object, e As EventArgs) Handles butSubmitOrder.Click
Dim sqlConn As New SqlConnection

I am not sure why this code doesn't work. I have follow according to the table field data and it I am still unable to get the SQL Datareader to work. I have checked the tables and all datafields, everything is correct. But I still am unable to read data from the database.

View 19 RepliesI have a strange problem in my VB.NET project when I want to compile it as x64. If I set the target CPU to Any CPU, it will be fine and on x64 systems it will run as x64. But if I set the target CPU to only x64, my project will show up some error/warnings and won't compile at all, here are them:
Error 1 : An attempt was made to load an assembly with an incorrect format
Warning 2 : Possible problem detected while building assembly 'x': Referenced assembly 'mscorlib.dll' targets a different processor
Warning 3 : Possible problem detected while building assembly 'x': Referenced assembly 'System.Data.dll' targets a different processor
Warning 4 : Possible problem detected while building assembly 'x': Referenced assembly 'System.EnterpriseServices.dll' targets a different processor
This is very strange, those are system assemblies and my project is .NET Framework 2.0. How they can run when my application is set to any CPU but not at x64 only?!

In a program I am writing (in VB.NET, 2008), I have 2 classes, "Receipt" and "Group", each with similar properties, both implementing a custom interface entitled "IIDUser". In my program, I have a number of lists of "Receipt" and "Group", declared like:Friend receipts as List(Of Receipt)
I have written a few functions that apply equally to managing both lists of receipts and groups, declared like this one:Friend Function getNextAvailableUserLabel(ByRef theList As IList(Of IIDUser), ByVal startLabel As Short) As Short
Then called like this:getNextAvailableUserLabel(receipts, s)
I did all this in an attempt for interface-based polymorphism, as I thought writing 2 identical functions (except for that one would be for lists of receipts while the other for lists of groups) would be bad practice (and waste time). However, I get an "InvalidCastException" during runtime. It is explained, "Unable to cast object of type 'System.Collections.Generic.List`1[Receipt_Sorter_v2.Receipt]' to
