Application Crashes For Other Users
Jun 8, 2010
I recently finished an application which I spent a long time making, but when I sent it to my friends so they could beta test, everyone single one of them said it stopped responding on start up. I took the .exe out of the project>bin>debug>application.exe and thats what I gave them, and it doesn't crash for me, so i was wondering what might be causing it to crash, or if they would need extra files for it to work properly?
Also, when my friend opened it, he says he got an error that says:
Name: Microsoft .NET Error

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

I am writing a system that utilizes the Timer to execute a command after an interval of three seconds. The command is to send a trigger to my RFID reader and hence the program will then decode the received data and changed it to information. It runs fine for the first few hours, but it will crash after that and the error given is an "System.NullReferenceExeption - Object reference not set to an instance of an object." error. Initially, i thought that it might be something that relates to my comobobox selected index change event that might be causing the crashes, but yet the application is crashes after i removed the section.
I fail to find the reason of the crash, even after spend fewing days finding the memory leak or some other events that might cause the crash.
I have insert TRY CATCH METHOD, just to catch the exeption error message that might cause by one of the codes, but still it doesnt show me.

I have created a program in Visual Basic 2008 Express Edition, and it runs fine on my computer, but on client computers (which do have the .NET |Framework installed), it crashes. I have ran Win dbg, and it says the program encountered a break instruction exception. I have googled a lot, but can't make the program work on client computers.

I have a VB application in .NET Framework 2.0 and I'm using VS 2008 Professional for development. The application is running without any problem on some PCs and it's not running on one of the PCs. To make sure that nothing is wrong with the that specific PC, I tried to reproduce the issue on my machine. So I formatted my PC and reinstalled everything. After installing .NET Framework and required drivers, the ran the application i got the same error. Then I installed VS 2008 and open the project to debug my code and then I realized that the exception is being thrown on this line:
********************************
Private Sub btnEnterRecords_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterRecords.Click
' Dim frmNext As New frmIncident()

We have an application that works well on XP/Pro, Vista, Windows 7, Windows 2003 Server, Windows 2008 Server (32 bit) but is problematic on Windows 2008 Server (64 bit). The application uses an unsigned activeX control which may or may not be related to the problem. To install we need to add the program name and regsvr32 as DEP exceptions. Once that is done the application installs correctly and operates normally except when the application closes.
If a user clicks the 'exit' button our code basically says 'unload me' (where me = the main form of the application) and there is no code in the form_unload section of the program.
Everything works well on every Windows platform except Win 2008 64 bit where we get
APPCRASH
Application Name: PDFPrint.exe
Application Version: 10.10.0.18
Application Timestamp: 4d238253
[Code].....
After we continue to close the program we see a message box with run time error 216 at 00002B24 message.

I have a small application (in VB.NET 2008) which gives the user the option to open a PDF document. This document is stored on a mapped network drive and is loaded in to the AxAcroPDF Control.
When closing my application I get the following message
The instruction at "0x0700609c" referenced memory at "0x00000014". The memory could not be read.
I've been google-ing this error message, but seen only a lot of problems, but no solutions.
I also tried using the WebBrowser Control, but this gives the same error.

I have an application with serial port datareceived event. My instrument sends me aprox.00bytes every 1 second. Which I then process and update few textboxes on the main formRecently my application started crashing if I press close button.I am guessing form_closing closes serialport at the same time datareceived event triggers in which the sp1.bytestoread causes the crash.1. I added synclock in datareceived and in form_closing.Within synclock in form_closing I removed datareceived handler.

I have a vb.net 2005 application that connects to an access database. I use Access Database Engine 2007 to connect to to this database.
Everything worked fine until i install MS Office 2010. After this, the application started to crash, returning the error 'application has stopped working'.
I've a Windows Seven Enterprise SP1 32bits.
When i debug the application, visual studio also crashes. I get the following error, closing an OleDbConnection: 'vshost.exe stopped working'.
I decided to run some tests. I installed my application on 2 virtual machines: a windows xp sp3 and a windows 7. When i installed ACE 2007 everything worked fine, but when i installed ACE 2010, thats when the problems began. This behavior ocurred on both machines.

We have a rather large VB.NET accounting application that crashes occasionally for some customers. I have now been able to reproduce this particular almost 100% in my test nvironment using certain data. The crash happens when clicking a list box after printing a report. The form involved has a list box listing available reports. You select one or more reports from the list box and click the print button. After printing, if you click the list box again, the program crashes, with an exception that does not seem like one VB.NET should even be able to produce.The exception message is: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."The call stack is:
1. System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)
2. System.Windows.Forms.NativeWindow.DefWndProc(Message& m) [IL offset: 0x3e]

I am having an issue with an ASP.Net page I am writing and struggling to diagnose why this page is failing.
I am trying to do this:
Dim st As New StringWriter()
Dim strURL As String = "CourseProgramme.aspx?id=3733"
Context.Server.Execute(strURL, st)
txtNotes.Text = st.ToString()
The aim here is to get the HTML back for the page that has been specified in strURL and then display it in a textbox. However when I run this code it crashes the ApplicationPool in IIS and when I look in event viewer I see this error message:
A process serving application pool 'blueprintdev' suffered a fatal communication error with the Windows Process Activation Service. The process id was '5284'. The data field contains the error number.The strange thing here is that in another page I do this code which works fine:
Dim strDutyStartDate As Date
strDutyStartDate = TextboxDutyStartDate.Text
Dim st As New StringWriter()
[code]....
As far as I can see other than the URL I am passing, which does exist, I cannot see a difference between the two.The page I am developing is in ASP.Net with .Net 4.0 however in the website there are some classic ASP pages. IIS is running at version 7.5.7600.16385 on Windows Server 2008 R2 64Bit.So far I have tried setting the application pool to run in 32bit mode but that causes errors in other areas and the site will not load.

There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

the error code points to a Stack-Overflow I can not pin the offending code down because the software works faultlessly on some computers after deployment but on others the crash occurs when a Gantt chart gets redrawn after changing activity dates. All the computers are situated on the same LAN and connect to the same SQL server 2008 database.The application has been developed with Visual Studio 2008.
I used the same install disk on all the computers and they are all using the same date/time format. The crashes occur on both 32 - and 64 bit machines.
The error message:
Stopped working
Problem signature:
Problem Event Name: APPCRASH
Application Name: Pfisterer Project Manager.exe

I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?

i am wondering if there are any case studies / white papers available comparing web applications to remote desktop applications on running on comparable hardware? What I am trying to get at is if a web application can support more users, as far as hardware resources go, than the same windows based application running on terminal services?

I have a rather popular application, and I was wandering if I could allow users to create add-ons for this software. I was unable to think of a method of doing this, and I do not know where to start. If you have any questions in order to provide a better response, feel free to ask.

I use a fontdialog box in my application allowing users to change the font details within my application. This works fine but unfortunatly I don't seem to be able to set the values in the dialogbox as they are read only.
Basically if the user has Bold Wingdings set and wishes to change it to something else then when they open up the fontdialog box I would like to be able to set the font to wingdings and bold so the user can see what they previously selected. Word seems to do this so why cant I?

I'm using the Application Updates option in Visual Studio with 'Before the Application Starts' checked.Users are complaining of canceling the update and then finding out they really want the update. When they decide they want to update there is no way for them to update the application until I publish a new version, because once they cancel the dialog box it never shows up again.
Is there a way to create a menu option to force a check for updates?
Kind of off-topic... Are there any open source Application Update programs for .NET?

I am writing an App that automates file uploads from users desktops to a specified file server. On the first run of the app, I need the user to select a file server and save it for all other users of that PC. I thought I could do this
with application settings but it appears it is not suitable for this purpose. I need suggestions on how I can make this work.
I thought about a registry setting but the user may not have permission to edit the registry based on group policy/security settings.
I also thought about creating an XML file with the file server name that I can read from the installed project directory, but I was hoping there was a more streamlined way.
