what is the fastest way of deleting all the files found within the directory, except any .zip files found.
Smells like linq here... or what?

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

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.
How can i delete image files (ex *.gif) that might be in use, by another process in a directory?

The code below displays a thumbnail of each image in a specific server directory and when I click on the image it pops up a nice full sized picture. It works perfectly.
I would however, like to be able to delete an image. I first thought I could have a button at the bottom of the page with a checkbox next to each image, giving it a uniqueID as per the filename but as they are dynamically created I couldn't figure how to handle the Click Event on the button for a randomly named Checkbox ID. Then I tried adding a button next to each item and then tried an OnClick & OnServerClick to call a Sub but this didn't work either.

I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.
I coded it with:
OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"
but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

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.

View 4 RepliesI'm at present looking at various ways on how to convert files without any extension and making them with a .txt extension. At present, I'm using the RENAME feature within windows to do this, but i takes time when there are a lot of files to rename. Can anybody give me a few pointers on how this can be done using Visual Basic?
View 3 RepliesI have a program that processes files in a special subdirectory and the program processes the files based upon the "Type", i.e., "Text Document". If an application, such as a text editor, installed onto the system, the "Type" may change to suit that application. For example, I recently had one change the type from "TXT File" to "UltraEdit Document (.txt}". Yes, the squirrely brace was on the end, don't know why. Well, after this app was installed, my program found no files of "TXT File" type to process even though the subdirectory was full of filename.txt files.
So, how can I get the code to look at the file extension, not the Type? A few lines of the code are shown:

I have to read SGI Files (I belive it's Suns Raster Image files, they have .rgb extension,but contains no header information), scale it, rotate it and maybe apply anti-aliasing filter to resampled image.I am just trying to read the image file. I read the file in byte array using FileStream and trying to display it in a image box, but it is throwing error while creating Bitmap class from the byte array. My code looks like this:
csharp
string imgpath = "Images\sample1_400x400.rgb";
System.IO.FileStream fs = System.IO.File.OpenRead(imgpath);

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 1 RepliesI have some code that launches a .bat file. The error comes from within the .bat file, navigating to the specified directory."F/Program Files/ Tversity/Media Server/data/ if i run cmd, then manually navigate to F/program files, i cannot navigate into any other directory within program files. Wierd..if there is an easier option to just use vb.net without launching a .bat that might help please let me know. i know i am not showing any vb.net code, but it just launches a .bat file. i know the forum rules, but i am hoping that someone might know why i can't navigate to my program files. it is not permissions, i am an admin on the local machine no domain.

I'm experiencing a wierd problem deleting some .csv files. Any .csv files named 1.csv, 2.csv, or 3.csv will not delete using delete() method of system.io namespace. if i do any number greater than 3 it works. For example, 4.csv, 5.csv, etc. works fine. 1.xls, 2.xls also is ok. The error it is throwing in my log is 'access to the file is denied.' Nothing is using the file. I even copied a new file into the directory and it does not work. I even created a 1.csv in a totally different directory with no luck. What is going on with this? Has anyone ever experienced this?
