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].....

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've used this in a couple of places and it simply doesn't work. Despit the try event, VB.Net still crashes or throws up an error.

My problem: I moved the original file (Project A) to another folder and extracted the unzipped Project A onto the desktop. When I open the new Project A's solution file, nothing happens besides VB starting up. It doesn't show me anything.
I am taking an Intro to Visual Basic class right now. When we do homework, we have to take it into class and put it into a folder that our professor has.When I save it onto my hard drive and I open it from Documents/Visual Studio 2010/Projects/HW Assignment 1, it opens everything perfectly. But on my flash drive, I have the same set up (E:/Homework Assignment 1) and I am not missing any files. But when I double click on the .sln file, it just seems to open the program without my project (display or code) showing.

But I'm running into a problem: whenever I open the project on my new laptop, it crashes!I can open other projects on my new laptop, including some copied from my old laptop. I can also open the project in question on my old laptop. So the problem must be some combination of things in the project, and the fact that it was moved
View 4 RepliesI 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.

When I publish my program I get no errors, and then when I install it on another machine it says it gives me the error that it can't read the txt file that it stores data in. If I hit continue it also fails to read the database. The database file is stored in the bin/debug folder and I told my program to include it when I first added the data connection. Anything I can do to have these included so my program can run on other machines?
View 6 RepliesI 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.

Tried searching and found some related issues but none exactly like I was having
I iterate thorugh a DGV and write to one of the fields of the row. After it writes this field, I do an update() command.
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

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

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.

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
