I know I've asked this before and for some reason I can never remember how to do it. I need to loop thru a directory structure and for every *.txt file, I need to open it and read it. This is a little application that basically searches for a given string. How do I do this?
View 2 RepliesI wrote a cleanup program to go through some directories and delete files based on if the creation date is older than say 6 months. It works fine with some of the directories I have that contain around a few thousand small files. However, there is one directory (that contains small backup files from another program) that is loaded with over 300,000 files and it locks up on me as soon as I read in the first file in that directory.I am convinced it is the directory has too many files in it to open it. The server that the directory is on is slow. It takes a half hour to open the directory while on the server itself. I know it will take forever to delete the amount of files I want to delete, but I don't understand why it gets stuck and hangs there with no error message.Here is where I get stuck. Listbox1 is the directory I'm attempting to access

I have created a project in VS2003.Net under VisualC++.-->Windows32 Application. I have to make an executable file that I will be able to run from different machine.The purpose of this file is to read some files that are in a particular directory. I will run the VSC++ .exe file from this folder. So I have to use some code to get the currentdirectory(directory where the current exe file is existing). After getting the directory, I have to find all the files in this directory that has an extension of .config.

I am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.

I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase
If f.Exists is False, mark it as deleted in the database
Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

I am trying to get the files in a directory and display them in a list box. I have that part working, but I would only like to show the files that are NOT hidden. I am currently using this:
Dim atts As FileAttribute = CheckDirectory.Attributes
If (atts And FileAttribute.Hidden) = FileAttribute.Hidden Then...
this is part of a for each loop.
But is there a way to only return the files that are not hidden, instead of having to check if they are?
I also need this to see how many files are in each directory so I don't have to count each file in each directory within the current folder. If I use the CheckDirectory.GetFiles().count, it counts the hidden files to.. A for each loop is just too slow..
