View 5 RepliesHow can I check if a file exists on a server? Let's supposed that I want to check if "[URL]" exists. How can I do that?
I tried to do this but it does not work:
Dim fso As New FileObject
If fso.FileExists("[URL]") Then
MsgBox("exists")
Else
MsgBox("File not found")
End If
I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

I have a database table where the user marks files to be downloaded. Subsequently, I browse this table and need to create a fileList to pass to an ActiveX downloader. My routine works locally and on the server for ONLY the first file. I know my logic must be bad, but I cannot find it. All of these files are always in the same server directory which is as follows:
"D:inetpubvhostsWebSite.comsessionVideos"

I want to create a text file or see if a text file exists when application starts. The problem I was having was after creating the text file, I tried to write to text file and got an error saying that another process was using it.

If System.IO.File.Exists(test) Then
MsgBox("File Loaded")

I looked up topics on filestream, but am unsure if this is how to use it. Is my code ok? Is there another way to create a text file?
I am working on a Windows Application where i need to check a file exists in particular library with user crediantials.
Note : .Net framework 1.1 (VS2003)
What I want my code to do is to check to see if a text file exists, and if it doesn't, it'll create one and write to it, but if it does then I want it to make the contents my label's text.
Here's my code:
Imports System.IO
Public Class Main
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

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:

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 have a simple program that opens up a text file and changes it and then what I want to do is save a text file when you click the "convert" button to the directory that the exe exists in e.g. "C:UsersBeaudeanDesktop--Distro--" etc. so say I have a richtextbox with the text in it I want to save and a button called "convert", when I click convert it will save it in the programs root folder with the name "main.html" and I also want it to overwrite any file with the same name.
View 3 RepliesI'm using the following code (System.Data.SQLite within VB.net)[code]...
I know the table exists because I can write to it via the command line through sqlite and through Autoit and can see it and edit it in the SQLite browser when I open the database. I don't understand why VB can't see it (I know it sees and opens the database file just fine).
Controls: textbox, combobox and button
I want to have a condition to find out if the value I enter in the textbox exists in the combobox. The combobox reads a text file.
I need a way to tell me if a certain word already exists in a multi-lined textbox. Right now I have a multi-lined textbox with some names inside it. After each name I add a newline so all the names are on their own line inside the textbox.I use this code to add names to the textbox, Text Box1. AppendText(ComboBox1.Text + vbCrLf)Then I have been checking if the name exists by doing it this way,[code]The problem is that Ted and Teddy return the same when searching for Ted even if Ted isnt in the textbox at all, I have googled for the last few days and even tried RegularExpressions and still the same results. I think this might be a simple true or false check but I may be wrong... or even a loop or something line by line.

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'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?
I have a little question about txt-files...This is the case: I am going to make a small software for editing particular parts in text files, so you don't have to do it by hand. In this program, i need to find several words in a text file and retrieve the text or number that is after the the "="-sign, and then replace that info. Then, I want to use the information it retrieves to add some text in the end of the file.
P.S. There are 36 differet words to search for, and some of them will occur in several places, so i want the data from those words that occur several times in an array. And the data i want to retrieve is AFTER the searchword and a "=", so i dont want the searchword or the equals-sign included. Can someone explain to me how to do this?
I have a database created and tables inserted into it. One of the tables is called UserLogin. It consists of two columns, BarcodeId and Technician. I have a barcode value, and what I am trying to do is check if any of the values in the BarcodeId column of this table is equal to the barcode that I have. Then when I get a match, I want to get the Technician that matches that BarcodeId and display the Technician in a text box.

I'm not sure if I am on the rught track or not, when the code gets to the line connection.Open during debugging, nothing seems to happen.

I want to check on the server for the existence of an image, then if it does exist, display the image wrapped in other code. E.g.
if "/images/name.jpg" exists then
<div><img src="/images/name.jpg"></div>
else
Do nothing.
Seems really simple to me but NOTHING I have tried has worked (compilation errors). I've tried examples using system.io, DIM stuff with 'FileInfo', Set fs. FileInfo examples produce 'not defined' errors, 'Set' says it's outdated and not used anymore and so on.

6 program to VB .NET 2008 that had code that used the CDO 1.21 DLL to validate if a mailbox entered existed on an Exchange server. I saw the one posting from Microsoft that states that CDO is not supported on the .NET Framework. As this is a client application, the article recommended using WebDav to interact with the Exchange Server.

I am making a program for work, i have it partly coded, unfortunately i don't have a wifi connection for my laptop right now which makes it hard to add my code here. What i am trying to do is have the user pull in a text file from anywhere on the computer using a open file box that pops up, i got that part, to make sure that is working i have a textbox that reads the data of that text file, it gets pulled in fine using a stream reader. Now what i need to do is search the text file for certain values, and depending on the selected item in the listbox which is on another form, change that value in the text file, im guessing i will need to use a stream writer, and ive seen examples used based on the file location(C:....) but in my case im not sure how to do it.
