How i can make a program to verify if files of a text file exists ?
Example:
I have directories.txt who contains:
Line 1: C:PasswordsAccounts.txt
Line 2: D:GamesFifa 11fifa.exe
So i can to verify if these two files exist?
But not: my.computer.filesystem.fileExists("for each one")
I have a series of text files in multipule diffrent sub directories. I found the following functions on the Internet:
CODE:
The functions will make a direcotry tree in my debug window, that looks something like this:
CODE:
What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.
Something like this:
CODE:
Any ideas on how to acomplish this?
I have an issue with avoiding this exception and trying to continue on with my code.im trying to search directories for a file. this is my code
vb.net
Dim As FileInfo() = d.GetFiles()'Errors here
Dim fFile As FileInfo
For Each fFile In Files
If Not fFile.Attributes = FileAttributes.System Then
If fFile.Extension = Extension Then
[Code]...
It's the files located in the C:System Volume Information Directory.How can i avoid the exception but continue on. I can't put a if then statement around the variable declaration. because then i can't use the variable. And catching the exception just causes my routine to stop.
i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo
[code]......
However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.
I got some code that im try to make search and text file and replace it. The code im using to replace it with is whatever the user entered in txtURL.text. Here is what i have
Dim strFile as String
Dim result as String
strFile = "C:\test.txt"
oRead = IO.File.OpenText(strFile)
result = Replace(oRead.ReadToEnd(), txtURL.text, "1F.php")
oRead.Close()
Is this writing it back to the file also....I think that might be the problem, not sure..
one of the BIG hurdles in my simple project, making a search engine. I don't know how at all. The search engine need only to search in one Directory with its sub directories and txt files for criteria, and display the results, with option open from the results. any basic code or example maybe?

Im learning Visual Basic 2010 on my programming class and we reached the part of file handling. Here i tried to make a simple program that can create a text file with the content of what i type on the textbox, basically i create the file if it doesn't exist, and if it already exists i append the content to it. Once the file is saved i can read it using the "Open" button. Unfortunataly, whenever i try to create the file, the compiler gives me an error saying that it cannot modify a closed file, although i've followed up the execution instruction by instruction and i can't find the error.

use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox.
