Whenever Run The Program And Enter Text Into The Label The Program Crashes?
Oct 14, 2011
Public Class Form1 Private Sub Button1cmdRun_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1cmdRun.Click ' Variable declaration & initilization Dim hour As Integer Dim minute As Integer Dim second As Integer ' Validation If IsNumeric(txbTotal.Text) And txbTotal.Text Then >= 0 Then ' Total number of seconds Dim totalSeconds As Integer = CInt(txbTotal.Text) ' Calculation hour = totalSeconds 3600

Whenever I run the program and I enter text into the label the program crashes. When I type in a negative number the message box works. A number like -45 worked and a message show appeared, whilst a string like 'bob made the program crashed.

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 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 am currently working on a program, that you enter certain values/text in and it organises it into a word document automatically,
I found a code online, which has worked a treat, However I'm wondering what lines of code I would need to:
1. Add Bullets or Numbers
2. Add a new line of text (I can add a new paragraph but I don't want a huge space between the two lines)
3. I have around 20 check box's is there a quicker way to check which are selected then write the text in word or do I have to write alot of If Checkbox1.Checked = True then, etc)

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 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.

I want to read a text file and write the lines on different labels. Is it possible to generate labels?
I tried with four labels with label1, label2, label3, label4 names but I don't know how to create a loop to read every line of the file and write it in every different label. First line in first label, second line in second label etc.[code]...

I'm trying to simply center the label text in the middle of my program.I put the label control in the center of my form. It starts out blank. Then, it receives input from the return values of MySQL commands being sent out to a server.When it receives the message, it displays like this:
|-------->
.. with the "|" being where the label starts.I'd like it to center the text like this:
<-----|----->
Is this possible. Hopefully I explained it clearly. I had no success with the text align property or modifying the anchor property.

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
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.

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.

I am still a beginner programmer so keep in mind that what I'm trying to do is beyond my knowledge but I have no one to teach me Visual Basic except from what little I can learn off of the internet. Currently, I am using Visual Basic 2008 Express Edition so my problem may be appear different if I show you any of my code.
I've created a program that contains a label and the words in the label form a question. Below that is a textbox with some text that has to be memorize for a play. Just think of the question as the previous speakers part. So far I've set it so that the words in the textbox are randomly removed and are replaced with a blank. I face with the program is that the user can't enter the answer because the blank is in the way.
Instead of putting a blank where the missing word is I would like to have some textboxes put there that way the user can enter the missing word and so that I can later insert some code that will let the user check to see if the answer they entered is correct.now the missing word is still replaced by the blank so I need to get rid of that and insert the textbox wherever the words are missing.
