Program Suddenly Stops While Debugging With No Errors?
Feb 22, 2012
I've built a windows form application that steps through a wafer map and sends a command to ink specific dies if the bin number is between certain values. While debugging I have run into an issue with the program crashing with no error message anywhere. While stepping through my code, the place the program stops has occured in two different places but both in the same subroutine in the code I use for the network communications. Below is the subroutine I've seen it break on with the two places it has broke indicated.
Private Sub EventHandler(ByVal Args As EventArgs)
Select Case Args.EventP
Case EventPointer.Connected
RaiseEvent Connected()
I'm having trouble getting my archive service working. The service counts files in a directory and sends a email. Pretty simple. However, it randomly stops working. I debugged the service and found nothing wrong. I also have it writing to the eventlog so that I can use it to determine where it fails It progresses through each function normally. I thought my program was failing at on point, because it was only posting "Email Notification Service is Running". However, I realized it wasn't posting to the eventlog source so I've been playing around with different ways to post the message to the eventlog. Am I missing something from my code below? I'm really scratching my head with this one.
ive been building a app, and have a beta tester who is on xp, im on vista x64, the app works great t my end, an dive also tested it on another pc with vista x64, and on a laptop wit win7 32, Now my beta teste has been testing fine on hes xp rig, up untill today when the WIP build i sent him started kicking up errors all over the place, try as i might i cant narrow it down to were the error is, heres how the app looks on vista and win7:[code]So i thought it might of been something i changed in between the working xp version and the wip but, all i changed was the page title, nothing else, no code etc.
The user has been running the app in question for over a year with no issues like this (this is a VB2008 business/database application with an executable 4.6 MB in size). Starting last week, "all of a sudden", the user started getting INTERMITTENT error messages like the following:
Exception has been thrown by the target of an invocation. Creation of the ImageList handle did not succeed. Out of memory. Parameter is not valid.
The last two have been accompanied by the big "red cross" on the form (in the screen shots the user sent me).The fact that the one message mentions "ImageList" and poking around on the Internet for answer on "Parameter not valid" points in the direction of a graphic problem, but nothing has changed in this area for a long time, and the app only uses graphics in a very straightforward way, using images on buttons and menu items, but not doing any in-line graphics methods.

I am attempting to teach myself VB and write a parental control application at the same time, so my learning curve is rather steep. However, I have managed to complete the design of the application with no design time errors, and to my untrained eye, all my code looks like it should work. Unfortunately, when I attempt to debug the thing, it returns an error that looks like Greek to me. I have traced to line numbers I found mentioned in it, but I couldn't find anything wrong. I just need someone to point me to the part of my code that isn't working, and maybe give me an idea of how to improve it.
The project consists of 3 forms: MainForm, WarningForm, and AboutForm. The 1st and 3rd are self explanatory, the 2nd is simply a message popping up telling the windows user that they have 10 minutes before they will be logged off of windows. I cannot imaging why any of the codes on the 2nd or 3rd forms should be causing this issue since they don't activate until either a button is pushed (AboutForm) or after a certain number of hours has elapsed (WarningForm). So unless someone feels that it would be helpful, I won't post those on here.
I have code that has no output, it doesn't do what i want it to do, but i can't see any errors in it, there are also no errors in the compiler, but in debug mode there are the following errors:[code]

I have an VB ASP.NET (.aspx) file that has deeply nested logic and I'm getting lots of build errors like "If must end with a matching End If" and "Do must end with a matching Loop". How do I begin to debug this beast to at least get it to build?
I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.
I was in correspondence with someone using my program and he verified that on his system, XP won't shutdown/restart either if my program is running.
Basically what happens is when XP gets to my program in the shutdown process to terminate it, the whole shutdown/restart just stops. I have to exit my program, then start the shutdown again.
The person sent me an image of some threads that were still running after the shutdown process halted and I was curious if anyone might be able to shed some light on this info and what to do about these threads.
These are the threads that are running and what they do: mscoree.dll - a module containing the .NET Framework functions. mscorwks.dll - Microsoft .NET Runtime Common Language Runtime gdiplus.dll - contains libraries for the GDI graphics interface.
I have a form with 3 background workers. On the click of a button all three start async. Once they all finish my program stops responding. If I run one at a time I encounter the same error.

And here I am with a new problem in my program When I debug it everything works fine (the buttons, progressbars, pinger, spambot, When I compile it and run the Executable file, it works too.When I run the Executable file on another computer (tried on 4 different ones) the program stops working and I get this error:
{$ exception. "Failed to create the form For more information, see Exception.InnerException error: File or assembly ." Microsoft.VisualBasic.PowerPacks, Version = 9.0.0.0, Culture = neutral, PublicKeyToken = b03f5f7f11d50a3a "or one of its dependencies not found. The system can not find the file specified .."} System.Exception {System.InvalidOperationException}
I m using access database and vb.net. My problem is that execution of program stops at third and sixth ExecuteNonQuery() methods because they are of string types and i am not able to understand the cause. I have also tried a single insert command but it gives syntax error so I used separate insert commands. The rest of the values are getting inserted properly.
is missing. Please build the project and retry, or set the OutputPath and AssemblyName properties appropriately to point at the correct location for the target assembly.
I recently made some obvious changes to one of my programs (added a few buttons, etc), and when I start debugging, it goes back and uses an earlier version before I made the changes.
I'm having to write a reporting application that gets information from some Interbase servers and it also has to work on Vista as well as XP, I'm using to connect Borlands Data Provider.[code]My Issue is that debugging on my xp Machine the dataset gets filled, debugging on my vista box it fails ("Interbase provider initialization failed"), my initial thought was that this could be UAC related but I've compiled the application and 'ran as admin' and still same issue. (by the way it failes on the line Dim da as BdpDataAdapter...)
My program hangs during debugging at a breakpont set at a subroutine call. It hangs on breakpoints anywhere inside the subroutine also. But does not hang otherwise at other locations where I have set breakpoints.
I am trying to create a new library (.dll) for use in my SSIS project. I dont have any prior experience of creating these kind of projects. So please bear with me.
When I try to debug the program, it throws the following error
What would be the best way to debug the following code. I know that it maybe wrong, but I am trying to learn this.
I've been using a piece of code I found that reads in joystick movement into my VB application using DirectInput. Building an executable works great, the program operates as should be, however when I publish my program for final deployment, I get the following error:
"WindowsApplication has encountered a problem and needs to close. We are sorry for the inconvenience."
I just got Windows 7, so I re-installed VB 2008 Express and have been met with some weird issues. One of which is when my program is running it used to break on a line where an error was occurring and tell what it was and let me fix it and continue. So I can see the error in the Immediate window but why is it not breaking on the line? It just continues loading the program. Is there a setting I'm missing?
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.
for our culminating activity we must make a program that uses a bunch of things etc.
i decided to go the extra mile and make sudoku.
The problem lies in generating the puzzle, the program always crashes, but there is never an error. im sure there are easy ways to make the generator, but from what we've learned this is the only way i know how to do it.
i made a function for each 3x3 square, and what happens is the block its currently on, checks for interferences horizontally, vertically, and within each 3x3 square, because computers process in order, i set it so that it only checks for previous block interferences, since this is the first 3x3 quadrant, there are no previous horizontal/verticals to check.
The code works fine, the problem is when i run it, it says its running but no form appears, i learned to use a progressbar to try and separate each 3x3 block to generate individually, to try and split the processes up 1 second at a time. the problem is, it does run, but it only generates a certain amount before it crashes, and every time its different, sometimes it generates half the puzzle, sometimes 1/3rd, sometimes only the first quadrant.
Is there a way to return only a set number of decimal places when using the mod function? My 'ones' equation seems to be rounding up? (I'm assuming I have the wrong idea about '\')

Is this program very inefficient? Based on the past programs I have written for this class, I would say I've probably done it again. I don't think I have written a single "efficient" program yet. =/
I have compiled a project with no errors and published the release version through ClickOnce to my website, almost 5 users are working ok with the application but on 2 computers the appliication fails when a button is pressed the exception is "Index was out of range.Must be non-negative and less than the size of the collection. Parameter name : index" Note that no parameter is named index in my code and that the program runs fine on 2/3 of the computer's I there is an error why does the application compiles?Also i have send my project file to a friend to use on his own visual studio to check if it compiles and the errors appeared in the debuger despite that i havent managed to find a solution, i beleive that my code is probably ok. I'm using visual studio 2008 with Option Explisit and Option Strict On and all the deployment pc's have .net 3.5
