File I/O - Getting Name Of Last File Of A Set Of Files With Similar Set Of Names
Feb 24, 2009
How do I get the name of the last file of a set of files with similar set of names? I have sets of files with the similar names beginning with the same characters such as: D1A2-1.jpg, D1A2-2.jpg, D1A2-3.jpg, and D1A2-4.jpg. The set keeps changing (by adding new files of the same set up to it). I want to get the name of the current last file, for example in the set above it should be D1A2-4.jpg. How can I do this in VB2005?

I want to see the name of the image files each time imagebox shows an image from imagelist. There's 117 images loaded into imagelist. How can I do it or which object/properties can I use?
I had to develope a program that shows a list of names and age in text editor. I am able to open the file in text editor but not getting the names and ages when typing it in the text box and clicking my "write button" or the file menu write. Everything else seems to be working fine with the exception of getting my message box twice from the event load. I don't know if the below is enough for you to assist me but this is what I should see in the text editor:
I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
I made project using VB.Net 2005 with multi languages, the first form is MDIParent form with MainMenu and toolbars also there is some changes in properties as righttoleft and text of forms.In my Mainmenu (Menustrip) there is opetion to change the UI Culture and I have already done but I need to change all texts in the form as mainmenu items anf form properties.My quetion is: how can I reload my form again to read the new texts names and mainmenu items names from resx file?
I have an array of filenames, and an array of files in a directory. I use a for loop in a for loop to check if those files are in that directory. Look at the below code to illustrate my problem. [code]
I've got a setup where a ComboBox displays all files in a certain directory, but it shows each files path/directory, and it also shows the files format next to the file name (i.e. "filename.txt").

I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code: Dim di As New IO.DirectoryInfo(strPath) Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt") Dim dFiles As IO.FileInfo ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I am experiencing a problem when trying to convert a rather large VB6 application into a .Net 2005 application. Everytime I try to convert the project I get the following error: "Upgrade Failed: Exception occurred: Can't use character device names in file names"The weird thing is i have tried to convert the project using .Net 2003 and I do not get the error, it does convert.
Basically I'm trying to make a file browser similar to what XBMC has, a file browser that you navigate with your arrow keys.This is the custom UserControl I made:
The small box on the left will be an icon, I will have a custom icon for directories/files. The label box that says title will be the name of the directory/file.
What I need to know is How to get the name of the directory/file so I can change the Title labelbox text to match the name.How to distinguish whether it's a file or a directory so I can set the picturebox to the right icon.How to create a new UserControl for each directory/file
I am interested in uploading an image to a file field using httpwebrequest or similar however I am stuck on a few things. Would it be a matter of add the file field and the image I would like to upload as the value? I'm not looking for code, I would like to learn how this can be accomplished.
I am currently working on file carving techniques and found that outlook has to be original and have its own files in a file (file system) going on. You guessed it the wonderful PST file. right direction on opening PST files without outlook if possible.
I am writing a backup program that zips files. Using some sample code I have the following that creates a zip file. Problem is it does not get any subdirectories or files. Where am i going wrong?
Dim azFileNames() As String = Directory.GetFiles(SourceFolder) Dim objCrc32 As New Crc32() Dim zipStream As ZipOutputStream
[CODE]...
Alternativley, there is another component to the zipping dll that I could probably bypass the above altogether. It is: FZ.CreateZip(DestFile, SourceFolder, True, "", "") Where DestFile is (Output stream as system.io.stream). I'm trying to read all the files, directories, sub dir and files, etc from a specific location, let's say 'My Documents' into Destfile in which the FZ.CreateZip zips the file. FZ is FastZip which is from icsharpcode.net. They have c# examples, but that's greek to me. I'm trying to just learn VB!
I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?
Looking for an idea of where the best place to keep files for a program. I use them frequently and they interact with the program directly. I want to place them in a place where they won't be easy to find if someone is just cruising thru the directories. Any ideas?
I have a new app im making... its for a mod im making for rFactor now for ease for the testers getting updated mod files im making a download manager (i have done that bit already and it works) but what im trying to do is put a list box on the form so they can click the file/zip they need to download and click download.. now i know how to get a list of file/folders from a dir on my pc...
Dim dir As String Me.ListBox1.Items.Clear() Dim dirs() As String = Directory.GetDirectories("C:\")
[CODE]...
But is there a way i can do this for my webserver? i have lloked on google and cant seam to find anything.... i was going to make a auto updater and i see some source code on code project but as im still pretty new to coding i dont think im ready for it.
Im not grasping something here.I can populate folders in listbox's but dead in the water populating files in listbox's.
Option Explicit On Imports System.IO Imports System.IO.FileInfo Private Sub ListBox5_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox5.SelectedIndexChanged
I am using the following to poulate a list box with the file names in a certain directory...lstImages.DataSource = IO.Directory.GetFiles("C:UsersLBDesktopSTRImagesPumps")This works, and does populate the list box, but it shows the full path on each line...
When i want to download a file with my own browser, there is a problem. when it gets the file name from the URL there are symbols added like "%20" and it dont get the extension of the file. (look at the printscreen)How can i get the file name without the symbols and with the extension?
I am trying to create a small application that will pull values from a config file (which is working) and then based on those values will search through directories recursively for files with specified extensions. In the end I would like these files deleted but I also need to have the app write a list of each file that is successfully delted to a .log file.Here is what I have so far, the values from the config file are successfully being passed to the sub routine however nothing is ever written to the .log file.
Sub activeRecursive(ByVal activeStat AsString, ByVal rootDirectory AsString, ByVal fileExtension AsString, ByVal maxAge AsInt32) IfNotDirectory.Exists(rootDirectory) Then EndIf Dim tmpFile AsString = "C:Files.log" Dim objWriter AsNewStreamWriter(tmpFile) Dim allFiles() AsFileInfo Dim dirInfo AsDirectoryInfo dirInfo = NewDirectoryInfo(rootDirectory)
i'm having a bit of trouble. can't seem to add ONLY the file names, without path or extensions to a list box no problem there with a a textbox. also the code i have to get the file to open in a textbox is a bunch of runaround (get's the job done though) but includes a few labels, text boxes, etc. i need a simpler code if possible.
I wanna put the files that ends with ".dll" which in the EXfile pat in a listbox in my program so know It's kinda easy question but I'm a begginer, I was using vb6 & there were a FileListBox Tool it was
how to list names from a file, as you enter (spell) the name. eg if you enter 'b' all 'b' names will appear. If you next enter 'e' then all 'be' names will appear. repeating this until the last letters are entered. eg 'bell' will show all names starting with 'bell'. You can then select from the list the correct name?
