Error When Opening Text File - FileNotFoundException Was Unhandled - Could Not Find File At Xxx
Feb 15, 2012
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 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.

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.

I have a project to complete and i have begun the code. What i want to do is go through the text file and find evey | (pipe) symbol and change it to a , (comma). I have the code and worked out how to do it but the code will only work for the first line. I was just wondering whether any of you had any advice on the way through this problem because i am stumped.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As_ System.EventArgs) Handles Button1.Click

I'm trying to upload a file via FTP from my local computer to an FTP server, which is also on my local computer at the moment. I've got this sub I'm calling:
Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential(username, password)
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.

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'

I've got an application that passes commands to a terminal window and saves all the output to a text file Here is one of the commands my application passes to the terminal
MyProcess.StandardInput.WriteLine("host " + device)
The output of which is
"HostA has address Y.Y.Y.Y"
this along with a whole bunch of other text is saved to a text file...my question is how do I find the sting "HostA has address Y.Y.Y.Y" in that text file and then extract the IP address and assign it as a string variable?

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.

Dim excel As New Microsoft.Office.Interop.Excel.Application()
Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w))
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

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'm having trouble opening a text file to process and order the data in it. When i try to read the first line of characters an error message occurs saying: 'Variable words1 is used before it has been assigned a value.' I dont understand what i am doing wrong when opening the file. Also, I am sorry if this is a rather basic question.

I'm having some trouble using resource files. In my project I'm using a bunch of bitmap files and two txt files. Bitmaps are used as backgrounds for controls, but .txt files I want to open in Notepad or WordPad. Till now I was accesing them from a file path on my machine:
ControlName.backgroundimage = New Bitmap(direcorypath & "/Map.bmp")
Process.Start(direcorypath & "/Instrukcje.txt")
And it worked fine. Now I added these files to my resources (it's practical for me to have them in executable file) And replaced those lines with:
ControlName.backgroundimage = New Bitmap(MyProject.My.Resources.Map)
Process.Start(MyProject.My.Resources.Instrukcje)
For bitmap it works fine, but for txt file an error occurs saying that a file cannot be found.
Interestin thing is: when I type "MyProject.My.Resources.Instrukcje" in "Watch" it shows the content of the file. So it is there, only not as a file?
