VS 02/03 OpenFIledialog To ImageList To FileNames?
May 12, 2010
I am using VB.net 2003 to work with a bunch of images. Using OpenFileDialog I populate an ImageList of image files. I can easily scroll through the images, but I would like to get a list of names of the image files so that I can work with these image files later in the program. I've looked at several good postings in the CodeBank, but have found nothing that I can figure out how to use for what I want. My 'textbook' on vb.net 2003 is Sams Teach Yourself Microsoft Visual Basic .Net 2003 in 21 days. While I view this book as excellent it does not give the info that I need in any way that I can figure out how to use,
When the user selects a file it should add a item with the name of the file to a listview. But when the user selects multiply files it just takes the name of the first file, so all items get the same name.[code]...
I have files that start with unique numbers and are word documents. Say the document starts with "1234567" is there a way to make the OpenFileDialog filter to where only all the .doc files that start with "1234567" show up?
I'm a relative novice at coding in visual basic 2008 and am trying to implement dragging and dropping filenames from windows explorer into a listbox within my VB app. My customer wants to do this as opposed to selecting filenames from a directory browsing window.
Private Sub OpenFileDialog2_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog2.FileOk ListBox1.Items.Add(OpenFileDialog2.FileNames)
I am using this code to get a list of files in a folder:
Dim files() As String = (From file In New IO.DirectoryInfo(myFolder).GetFiles Where file.Extension = ".exe" Select file.Name).ToArray
This works fine, but the problem is that it selects only files with the extension of "exe" & skips files that have an "EXE" extension. Is there any way to make it case-insensitive, to make it return any combination of upper/lower case letters in the extension?
I have a string of filenames separated by commas that I want to add to a listbox. This is how I'm currently doing it: vb.net Dim FileNameArray() As String myFileNames = tblOpenTemplate.Rows(0).Item("filenames").ToString FileNameArray = myFileNames.Split(",") For i As Integer = 0 To UBound(FileNameArray) .ListBoxFileNames.Items.Add(FileNameArray(i).ToString) Next i
But I've been reading about using: vb.net Dim FileNameArray As New List(Of String) How to populate this with string of filenames?
I have this app that suppose to read images from folders and display them. What I'm trying to do now is to use the file names and use them to query the database. [code]...
I need to display the Browse for Folder dialoge on button click event. I have some how managed to start File Dialog form, however that is not what I need.
I have two pictureboxes both with images in them i want to see if the image in picturebox1 is the same or has the same filename as the image in picturebox2
for labels i would do if label1.text = label2.text then
is there anyway to do somthing like if picturebox1.imagename = picturebox2.imagename then ?
I am sure this is a simple question to the more advanced, however, to the less advanced I am having a problem. I have to come up with a quick program (that works) for my job (I am a systems admin) that will either look in a database or excel sheet (which ever is easier) and find copy files from one directory to another. I know how to move, copy and delete, however, I need it to look for the specific filename.
The code below creates multiple folders based on different file names and moves those files into the new folders. For example, files ABC and XYZ are moved into a newly created folder named ABC and XYZ. I want to advance the code to allow slightly different file names to go into a common folder. Example, I want file ABC_rock, ABC_soil, and ABC_water to be put into a folder named ABC still, AND file XYZ_rock, XYZ_soil, and XYZ_water to be put into a folder named XYZ. I do not want a separate folder created for ABC_rock, ABC_soil, and ABC_water.[code]...
I'm trying to do something to delete a folder with files and subfulders ,my problem is that sure that the one or more directorys are with full long names. So what i can do?
I am trying to fill filenames from a folder into a listbox. Now what i want to achieve is that if in the folder there are 2 files with same name but different extension for example song.wmv and song.mp3 then i want to show only .mp3 filename in the listbox. This is how it works in VB6. PERFECT! How to make this code work in .net.
I am creating a text editor in Visual Basic .Net 2005. I want to get the list of filenames dragged into the MDI form. I can't figure out the proper code to do that.
I have a program in which I need the user to be able to import multiple image filenames into a listbox. Here is my
vb.net Private Sub ImagesToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ImagesToolStripMenuItem.Click Dim import As New OpenFileDialog
I'm trying to figure out how to make the code from HTML url...I have in a listview with some pdf filenames..each of these pdf's have bookmarks to other pdf files.I managed to get the code to export the bookmarks and load them into the listview..but only the first listing seems to be working. when it gets to the second listing,, when it gets to the exportbookmarkstoxml function..it hits the catch from then on..i've tried several different things and none of them seem to be working..the code i have is somewhat messy because i been messin' with it,,but i'll try and tidy up as much as possible for ya.I'm thinking that something between the using statement needs to be closed or something but i can't get it to come even close..i even tried closing the reader with reader.close and then deleting the outputxml and then making the file again but that isn't working either.

Do you know of a method to read dbf with filename more than 8 chars?I'm stuck here because all my dbf's have long filename and is located on another networked server. Copy and rename the dbfs to a short file name to the web server.
I have a list of files I need to add to a Treeview in the correct 'format' (each directory one main node, carrying a child node for every file in that directory, and a child node for every directory in that directory). So for example, if my list of files is this:
How do you remove unwanted characters from filenames?To get my program to run without causing errors it needs to remove characters from filenames like spaces, "." and "_".What it needs to do is to scan a folder which old the files and remove any unwanted characters from them.
continuing my project my AV can detect viruses by its filenames.. or fileextensions.. and its a incorrect form of detecting a virus..how will my program detect viruses by its behavior?.. least the common viruses like worms and trojans..
I have a sorted array of files saved in the following format of filenames:
XXX XXX_XX XXX_XX_XX
I want to insert a new file (with a unique filename) between two given filenames (which could be in any of the 3 formats above).
For eg., a new file between 401 and 403 could be inserted with name 402 and a new file between 401_01 and 401_02 could be inserted with name 401_01_01. etc
The idea is to conform to the sorted list. Is there a way I could generate filenames for the files to be inserted, given the two filenames between which it needs to be inserted?
I am currently new to visual basic and I am using Microsoft Visual Basic 2010. I am trying to create a small game in which i want to use 8 images. These images are imported in my resources under images as _0.gif _2.gif up to _7.gif. I could write code for each of the imageboxes individually but i prefer doing it in an array as shown below. As you can see I use the variable "i" to run a for, next loop. picbox(i).Image = My.Resources._1 So that not every time it loads the image. _1.gif but it loads the images _0.gif through _7.gif, based on the "i" variable.
For i As Integer = 0 To 7 picbox(i) = [Code] .....
For Each tempstring In SourceDataCollection LineToFieldsTemp = Split(tempstring, ",") LineStringWithoutFirstEntry = "" 'reset the linestring For i = 1 To UBound(LineToFieldsTemp)
[code]....
essentially what i'm doing is to read through each item in a collection of comma separated variable strings. the first variable in each string is appended to a master filename and becomes the NEW filename to which the entire string will be appended. this is a way to split a CSV file into multiple files using the first variable in that string.
the trouble is that this is doing a LOT of writes to potentially a LOT of files, the IO is taking forever. is there a way to buffer this data until the end, then write it to a disk? be aware, the filenames and total number of files to be created is UNKNOWN at the begining of the loop. it just creates a new file each time a unique first column ID is discovered.
Dim subfileEntries() As String = Directory.GetFiles(FolderPath) For Each f As String In subfileEntries If (File.GetAttributes(f) And FileAttributes.Hidden) <> FileAttributes.Hidden And (File.GetAttributes(f) And FileAttributes.System) <> FileAttributes.System Then

The issue I'm running into is that 1 folder I have has 812 files in it and it takes a good 20 seconds or more to load the files with their Extracted icons. Furthermore, I ran into one instance where a .pdf file was given a system icon (sort of like the icon a .bat file would receive with the two gears) instead of the Adobe PDF icon.
So, my questions are: 1) Is there a better way to load files so that it will be able to get the icons and display them in the Listview faster?
2) Is there a better way of getting associated icons since the VS built in option seems fallible.
