I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()

The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.
I'm getting a suprising FileNotFoundException although i'm sure that the file exists.I simply wanted to add Logfiles(IO.FileInfo) as attachments to an email, therefore i tried to check the length of every file to detect if they must be added/zipped.This works fine if these files already exist. But if i've created them in this run, i get above exception when i try to check the length. It's oddly enough that i can write into these "not existing" files(actually FileInfo.Exists returns false) without a problem one line before.
Here is some code...
Creating one of the files in the constructor of a class named Log:
Me.LogFile = New IO.FileInfo(infoLogPath)
If Not LogFile.Exists() Then
'tried to use `Using` on the Stream but that doesn't change anything'

Why do i get this error ?I know the answer is staring me in the face but i cant figgure it out, i have been over the code so many dam times :/See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I am modifying an existing application in VB .NET. In one routine, I have added a reference to a class in a newly-referenced class library project that is part of my solution, and now I get run-time FileNotFoundException messages when the program attempts to access this routine while debugging. The error tells me that the class can't be found, what's up with that?
To be clear: If I remove the lines of code relating to the new class, I no longer receive the exception messages. If I add them back in, here they come again! I have referenced the class library in the project containing this routine. The class library is building properly (other projects reference same library, and use it more extensively), and the project is referencing the class library's .dll file in my "debug" folder. I get no errors from other routines that use this new class (thus far). I get no errors in the Error List of the IDE.

We have a vb application with many forms that contain a "lookup" button that has an icon called find.ico. Once in a while, a user will open one of these forms and get the below error but not every time. Has anyone else run into a similar situation? Since it is not consistent, it's been very difficult to track down.
Exception Source: System.Drawing
Exception Type: System.IO.FileNotFoundException
Exception Message: find.ico
I have a WPF application that has 3 projects in the solution. I have the main menu, which is the actual EXE, a reporting DLL and the application files DLL which both are a WPF Class Library. I'm getting the System.IO error when I'm trying to use a 3rd party reporting tool from in the application files DLL. I have the 3rd party DLLs referenced and are set to copy local in my application DLL. Everything works fine if i reference the 3rd party reporting tool in the EXE project but I don't want to do that. I want my DLL to be stand alone so someone else can reference my DLL without having to add anything but my DLL.

However a FileNotFoundException exception is thrown during File.Copy even though its wrapped in a If File.Exists ... End If to check its existance.
The great thing is if you run this through the debugger it nearly always works, when released as an app it almost never works.
I created a SQL application that synchronises with a SQLCE database when loaded. Works fine on my Dev machine but produces the following error on user machines:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'
In my attempts to fix, I have:
1) Reinstalled SQL Compact Editon 3.5 on the client machines
2) Reinstalled .NET Framework 3.5
3) Installed Microsoft Sync Framework 1.0 (which puts the 'missing' DLL onto the machines).
This still fails with the same error.

One of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.

This returns "Conversion from string "" to type 'Long' is not valid." I was wondering what the error is and how it's possible to fix it? The other questions that I've looked at were mostly to do with variables assigned incorrect types, but I think that isn't the issue. It occurs when all of the variables are empty.
This never happened to me, and the less data one has (usually) the less you can say what happened.I am trying to write a simple query analyser. I randomly receive these kind of crashes:

The file specified above does not exist. The place where it crashes is wrapped with Try-End Try. Moreover, yes, I have the painting event set up but it should not concern it (or maybe it does?). I have to add that I use visual basic express edition. The error occurs ocasionally - sometimes when I'm lucky nothing happens, and when I'm not then I get this crash.

All of a sudden, when I built my project, it wouldn't read any changes, then all of a sudden, this error started popping up!The description of the error is:An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.and it pops up when the following code is executed:
frmMain.Show()
on the line prior to it I have the code
frmStats.Show()
and that pops up no problem.These errors happened suddenly, and all I was changing in the code (which was in frmMain) were just a few changes to labels (activated by an event).
I get the following expeption when trying to switch from one form to another (click event):
