VS 2008 Error: Input Past End Of File
Nov 12, 2009
I have this program that excepts user input and does some mathematical calculations. When the user hits quit, the program saves all values that are entered and stores them into a text file called values.txt. Then when the user opens the program again all the values are there. But when I run the program, sometimes it gives me this error:
EndOfStreamException was unhandled by user code
Input past end of file I don't know what could be the problem. Here is my code to load the values and then save the values:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
SaveValues()
[Code].....

We have a demo program that was written and compiled in May of 2006, last used successfully during the summer of 2009. This program is stored on the development PC and a laptop, both WinXP PRO.The developement tool was VB 2005 Express Edition.Now we have revisited the demo program since there is a possibility of restarting the project. Today the demo program fails on both machines with the error - Input past end of file.
Unfortunately the original developer is no longer on staff or available to question. This leaves us to wonder if a Windows Update may have broken the once working code. Could this be possible and what update is the culprit?

I am working on tis program that excepts user input and does some mathematical calculations. When the user clicks on the button btnExit, to quit the program, the program saves all the values that were entered and stores them into a text file called values.txt. Then when the user opens the program again, all the values are there. The problem is that when I run the program, sometimes it gives me this error:
EndOfStreamException was unhandled by user code Input Past End of File I don't know what could be the problem. Here is my code to save the values and load the values:Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
[Code]...
When I try to comment them out, the program runs fine and I enter the values in. Then when I quit the program, I uncomment these lines and run the program again. It runs fine.and all the values that were entered before, are there. So I have no idea what could be the problem.

Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

Can I set this function so that if the local settings.txt exists, it will NOT be overwritten unless the mapped file is newer?
If IO.File.Exists("C: empsettings.txt") = False Then
IO.File.Copy("K: empsettings.txt", "C: empsettings.txt")
ElseIf IO.File.Exists("C: empsettings.txt") = True Then
[Code]...
Currently modifying a program that is being used by several staff. Each time they restart it, it starts the latest build.
I have a settings.txt file that is needed for the latest build(not on all pc's yet, original version has the settings written in the code) and updated as needed.
If local PC doesn't have settings.txt, it is copied, if it does have settings.txt it gets overwritten by the mapped copy on each run.
Wanting to let users keep their 'personalized' local settings.txt, unless I add a new feature to the program that requires a change to the mapped settings.txt file.

My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this:
Imports System.Globalization
Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick
Dim date_info As DateTimeFormatInfo = _
CultureInfo.CurrentCulture.DateTimeFormat()
ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern)
End Sub
That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
TextBox48.Text = Val(ToolStripLabel1.Text)
End Sub
Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable:
My.settings.12hourspassed
So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1
If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1"
End Sub
The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...
I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off?

Applications in the .NET Framework can use the System.Console class to read characters from
and write characters to the console. Data from the console is read from the standard input stream,data to the console is written to the standard output stream, and error data to the console iswritten to the standard error output stream. These streams are automatically associated withthe console when the application starts and are presented as the In, Out, and Error properties, respectively.I am working with redirects and I am solving small problems one at a time. So far so good, but I lost track of the big picture here. Can someone please clarify something for me.

I tried to accomplish this via a MailMessage.Headers.Set call, in VB.net. See below:
Dim objMail As MailMessage
Dim objSMTPClient As SmtpClient
objMail = New MailMessage()
objSMTPClient = New SmtpClient()
[Code]...
To be clear: I am not doing this with malicious intent. I am working on an e-mail integration component that utilizes both UIDs and a "Last processed" date to locate the first new e-mail to integrate. I want to test cases where multiple e-mails have the exact same date/time - as the e-mail integration module should handle those situations flawlessly. If I could simply fake the date this way, I could send as many e-mails as I wanted that matches a certain date/time, rather than trying to send them with an automated script - hoping they will all be received within the same second.

I have a combo box defined as a drop down list for a numeric field and have possible values under items. One of the values I have is a blank value (at the top of the items list) in case the user needs to leave the value as null. However, when I choose the 'blank' value, it will not let me past that field. I tried changing the 'data source update mode' to 'Never' and it let me past the field but then of course it won't save ANY of the values I choose.Is there any easy way around this without having to change the field to a string? I have several like this.

I'm using Try/Catch blocks for a program calculating payroll and commission. I've dim'd my variables, and I've parsed them inside my Try/Catch blocks. It appears as if my Try/Catch blocks have been coded correctly. However when in run-time, my format exceptions will show regardless if I provided a correct input.[code]Is there an issue with my programming? Or could there be a property I'm over-looking for my text boxes? I'm stuck.
