.net - Program Crashes With No Errors?
Apr 25, 2011
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.

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

I have an application that I have built that used a winsock control to send commands and receive data from a wafer map program. I have been converting the winsock to use the built in sockets in .net and so far things have been going fine. I have been able to get it to connect and send out a command to the wafer map. Yet I have having a troubling error that I can't resolve.

my situation is this; I have a search button which searches records with Surnames, when two or more records have the same surname, the first record appears and 4 navigational buttons appear, they are 'Go back to first record' (btnFirst), 'go back one' (btnPrevious), 'go forward one' (btnNext) and 'go to the last one (btnLast)'. All of these work properly except for 'go back one' (btnPrevious). When I click this and the record is currently the first one, the program crashes. Its probably a very elementary mistake but I can't figure it out. Here is the code for btnPrevious

The application is like a client for a game site. I made it for the fan site i am apart of to help the members of our community.The application crashes when you click play on the game at the site.

I write text to a file using StreamWriter as shown below several times a second. The problem I have is that sometimes these files are left blank after my program has crashed or the computer has crashed. I've done several searches on the internet without any results other then writing to a second file, copying over the file and then deleting the extra file when done. If this method doesn't have any error modes it still appears to be less then a beautiful solution. (What happens if the computer crashes when writing over the original file?)Is there a more secure method for writing the text file that doesn't leave it vulnerable? This happens way too often. I never find errors related to file writing. I really want this code to be reliable enough that I could just pull the plug on the computer
Try
Dim mSW As IO.StreamWriter = New IO.StreamWriter(countFile, False)
mSW.WriteLine(CStr(totalCount))

I am having Beta Testers go through my program. For some reason, the help file doesn't open but crashes the program. But it is in the program folder... I'm not sure why it is having a problem finding it.I created a try catch format because it seemed to have a problem at one point between looking in the 32 bit program folder or the 64 bit even though the program itself is in 64 bit...[code].....

my program crashes when my datagrid view is empty.
It crashes at this
M = Allow_grid.SelectedCells(1).Value
I know its because the grid is empty. when the grid is empty it has a "-1" as the selected value index right?
Is ther a way to test if the index is "-1".
if grid_selected index <> "-1" then
M = Allow_grid.SelectedCells(1).Value
else

Problem: The excutable of the vb program crashes when trying to run but when I step through the program inside of visual studio it runs successfully.
Details: The program performs a winscp.com transfer from a ftp server and then takes the downloaded file and extracts the data from it before sending it to a webpage. The program also decrypts a des3 encrypted file which holds the login details for the sftp server and the webpage.
My Thoughts: I was thinking this could be something to do with the excutable jumping ahead of the slower transfer and decrypt functions thus causing a "file not found" exception to be produced and the program to exit. Lending to this if I slowly (aka spend 10+ seconds stepping through the code) move through the code it works just fine.
As requested Crash Messages:(I capture everything in exceptions and exit properly so no "crash" is reported but the error I get in my logs is as follows:)
1st run with standard test case:Could not find file 'C:UsersAdministratorDesktop..ILC2INFOENC.txt'
2nd run standard case (the file above was not deleted by my cleanup function either as it could not be found)Could not find file 'C:UsersAdministratorDesktop..ILCNETSL10663.csv'
Background:The first file that is found missing is the encrypted login information file while the second file is the winscp.com downloaded csv file.

I've been having a bit of a problem using the while function.
Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer
[CODE]..............
When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.

I'm trying to make an auto updater. It kind of works, but I've got some problems.I need to make the download threaded or something so you can use the program while downloading. I've tried the background worker and now the Application.DoEvents(), but I didn't get it to work.
The second problem is that the program crashes after having downloaded in a while. It may be because it isn't threaded, but I don't know.Anyways, here's my

whenever my program crashes at college, an error message pops up in a window which tells me why the program crashed and points to the line of code which made the program crash. I have recently taken the program home to finish on my own computer but now whenever it crashes nothing pops up to tell me why it has just crashed.

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.
Private Sub FirstBlock()
Randomize()
intNumber(0, 0) = Int(9 * Rnd() + 1)
[Code]....
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

Is there a way to catch ALL errors of the program?
Purpose: The idea is to catch all the errors of the program, load errorform which basically just says "A Error Was Detected" (Which I have already designed). Then send a web request to a formmail.php file with the said error (which i have already done).
In short: I need a way to catch ALL errors, and get the error string that it gave.

Anyone ever get fake compile errors and rebuild the program and then they go away? Well mine aren't going away and I can compile and run no problem. I've got something like 100 compile errors and the "run with error's" warning doesn't appear at any time and when I do run my program it runs just the way it should. However I still see like 100 errors.

I am not exactly sure what I am doing wrong. I need to convert Me.xCommissionLabel.Text = Format(Me.xCommissionLabel.Text, "currency") to a toString, so it displays a dollar sign, 2 decimal places. so I did this. Me.xCommissionLabel.Text = commissionLabel.ToString(CType("C", IFormatProvider))When I run the program and input the data I get: A first chance exception of type 'System.InvalidCastException' occurred in Commission Project.exe.
