Dim di As New IO.DirectoryInfo("c:")
Dim diar1 As IO.FileInfo() = di.GetFiles("*.jpg")
How can i use multiple filter to retrieve list of files in directory.
i tried some examples for troubleshooting
("*.jpg|*.png")
("*.jpg,*.png")
But its only filtering one type of file. i need your help about that.
I am wondering if there is a simple method to filter the result returned by Directory.GetFiles(). Basically I am looking to retrive all of the jpg files in a selected folder into an array. My current code works fine if the folder only has jpgs in it which should be the case in operation but I would like to make sure it works correctly when the folder contains other types of files as well. The line I am currently using is..
Code:
files = Directory.GetFiles(IMAGE_DIRECTORY) files is defined as an array earlier in the program and as I mentioned my program works fine when the folder has nothing but jpegs within. The problem is that I am creating a listview with thumbnails from these files and run into some indexing issues when there are non jpgs in the target folder. The easiest solution would seem to be a filter on the getfiles method that would return only files witht he given extension.
Anyone know how to do this or will I need to parse the files out of the array in a second process?
I would like to filter files in a folder so only files with a preselected name format are shown the format is like this "**??????" where ** is two characters selected using the variable acpattern. and the file in the folder is assigned to the variable curFile. i want to only show curFile if it has the same format as acpattern.

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?

View 2 RepliesI 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..

I have a few questions about the following 1.What purpose does the first line of MSDN example serve? ystem.Collections.ObjectModel.ReadOnlyCollection(Of String) Why use this? I tried reading about it on msdn, but i couldnt make much of it.
2. Why use CStr in the msgbox? For me it works fine without it with Strict on. am i missing something?
3. Am i making a mistake using my own version over MSDN example? I dont like using code that i cant understand, which is why i changed it in the first place.

We have a directory of thousands of pdf files that need printing. How can I have a vb app print them one after another until they are all printed. All it needs to do is the equivalent of right click on the pdf and click print. I don't need to open or read the file and I don't need to monitor the printing process. Just go through one by one and say print to each file. I can loop through files but what would the commands be to tell it to print them?
