FileNotFoundException Message On Modifying Existing App?
Aug 16, 2011
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.

I've seen this great example of serial communication in VB.NET
[URL]
I try to use it in a project I am working on but somethings are not clear to me.
1: Now the send and received data is shown in one RichTextBox but I would like to split this into two RichTextBoxes (RtbSend and RtbReceived).It is unclear to me how and were data is assigned to the RichTextBox?
2. the received data is shown in the Richtextbox as one long line, I would like to get a new line for every send message.So for example: I I send "test" four times, I would like to see:
Test
Test
Test
Test
now I see: Test Test Test Test I've tried ctrlf but this does not work.The example describes that "comPort_DataReceived" is executed when data is waiting in the buffer. Where can I see the eventhandler responsible for this? How does it know data is waiting?The problem is this kind of coding is a bit to difficult for me. I want to understand the code before I implement it into my project.

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'

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.

The code is very simple.
If File.Exists(strFileMovingTo) Then File.Delete(strFileMovingTo)
If File.Exists(strFileMovingTo) Then
Call SendEmail(Globals.EmailInternetTeam, "dev-sql@fad.co.uk", "Display Jpg
[Code]....
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.

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()
[CODE]...
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 have finished coding an application which I designed for people working in my office. When I started to install the application to computers at the office, I realized that, in some machines, application doesn�t work properly. Although it worked for 15 computers perfectly, for 3 computers following error code is displayed:
System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

I have a core EXE I wrote to serve a series of purposes. Another editor that goes along with it needs to repackage that EXE along with the script that EXE interprets. That is simple enough.
However, I need to give users of this stuff the ability to give that repackaged EXE an icon of their own choosing, but they do not have the source code to manually compile that EXE.
I know some magic with file streams and binary manipulation could do this, but I have the sinking feeling that that's pointlessly doing this the hard way and there may be a better way. Maybe the EXE itself can reset its own app icon per instructions given to it.

I am populating data form database in combobox. This data is in the form of numeric codes like 112, 113,
The thing i want to do is on selecting some code like 113 from combobox, it will display it as ABC113 in the combobox.if code like 114 selected from combobox, it will display it as ABC114 in the combobox.
I don't want to store this modified string in database.
Please help me to achieve this.
Provide me some sample code or link for simple combobox or combobox in datagrid.

I've got to do some special things with a RichTextBox. I have to add syntax highlighting and I need
to be able to find out what character was added/removed/inserted at what position every time a key
is pressed. Is there some way to edit the existing, or is there a open source (.net compatible,
preferably VB.net) available for download? I've tried making my own, the problem is, it has to have
every function normally available and I don't have enough time to implement all of that.
