Searching A Dir For Special Files And List Them?
May 8, 2009
I want a form to search a directory (which i specify in the code) and then list all files with a file exstension that is .amxx .And that's not all, it should list them in a checked listbox.And of course a little + is that it only list the name of the file, not the hole directory + filename. But that feuture i don't really need, just for good looking.I looked into the problem and i tried something with DirectorySearcher but with no success.

i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like
Dim strTest As String
strTest = File.ReadAllText("ae.txt")
Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.

If I want the saved files from a application to get special icons, how do I do that in VB? For a f ew years ago when I programmed to Mac, in RealBasic, it was just to add icons and associate them with the extension.

I have been reading extensively about searching generic lists in VB.NET with the usage of delegates.However, I still cannot seem to grasp how to achieve what I want to, which I believe is frustratingly simple! I have a list populated with instances of an object with three parameters (fields/ variables).When I receive a new object to add to the list I want to search the list for the "layer" field.If the field matches then I will replace that row (object) in the list with the new object, if no match is found then I will add it to the list.

My problem is probably something simple..I am trying to load a list of a perticularcustomer.I will have to load the list of all the purchases they have make (amount of tickets purchased (rseat). It runs fine, but when I change the file name from fri to saturday and keep the call name the same it still searches to the name that is in the call name textbox. I dont want it to do that. I want it to say the there are no reservation for that name if I change the file.here is part of my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
'resets file reader and put to the top of txtfilename

I want to use a System.Collections.Generic.List<Of T> and store custom objects in the list. I then want to filter the list by my own custom defined criteria and return a System.Collections.Generic.List<Of T> of all the objects in the list matching my search criteria. For searching in Java, you would create an object that implements the comparator interface. The object would then be passed as an argument to the list's sort method. Is there an equivalent VB way to do this BUT when searching for items in the list?I have looked at using delegate functions, but these pass EVERY item of the collection into the function, which is not efficient in any way.

I can search all the images with .jpg extension and pass it to the fancybox gallery , The issue is i just want the images of particular productid for instance if a product has 5 images , and they are saved as (productid_imagenumber.jpg) , therefore a product with productid 99 will be saved as 99_1.jpg , 99_2.jpg similarly 99_5.jpg,I can pass the productID but i cant find a away just to get the images of that productID , instead of getting all the images which is done by the function below:
Dim directory As DirectoryInfo = New System.IO.DirectoryInfo("C:Images")
Dim allImages() = directory.GetFiles("*.jpg", SearchOption.AllDirectories)
Dim strContent As String = ""
For Each image As FileInfo In allImages

I'm creating an app that has check boxes that will define a search. The files all reside in one folder. I've looked at some tutorials that use io.directory.getfiles and I can get this to work. But what I think i want to use is: io.path.getfilename because I don't need the path (though I'm about ready to make an exception).
When should I use io.path.getfilename and can I use that method to do a search? I can't figure that out. I would think it would react as io.directory does but I am incorrect.....
Here is the code. Its short becasue I'm just figuring things out first:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim afiles() As String
[Code]....
The commented out line is what I can't get to work and I'm thinking that is what I need to work.

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

It seems simple enough, but apparently I cant figure it out. Theres more to my actual problem, but once I figure out this concept then I can do the rest. I want to search a list for a given string, and if it matches, then print it out. If it doesnt match, then it moves to the next item in the list. If if doesnt find any matches, it says "no matches found".

I need to scan all files on our solution (aspx, js, ascx, etc). Our solution contains 22 projects all in all. What I need to accomplish is to search for all files which contains "img=" in its content (not filename containing "img") I don't want to do this manually of course (opening and checking files one by one). How I can do this faster.

I'm trying to create a folder search operation. The folder will have several text files (.txt), and user will specify the folder path and a search string, and the program will search the exact string within the text files which are located in the specified folder, and show the files. So far I've done nothing. I don't know how I can do folder operations with vb.net. a link to reading material.

I am in charge of developing a searchable database which should allow users to search for any key term in every fils content in a folder. Note that I need to search for filescontent, not file name. Right now, users usually have to searchfor every file to look for particular filecontents with any key terms.

Okay so i have a very large list of string (500 000 strings) i want to check the number of duplicate strings and maybe even isolate the duplicate strings if i can.
i cant find a fast method to do so :S
i tried using a string array (slower than list) takes ~15mins
i tried using list with the code below takes ~10 mins
that wont cut it :S i need something faster.

I have a file search that I want the user to select the folder they are searching the file in. At the moment I have
If Check.Text = "Correct" Then
If My.Computer.FileSystem.FileExists("C:Systemsfile.txt") Then
1CheckBox.Checked() = True
Else
1CheckBox.Checked = False
End If
However this check will be used for various files and its not usable if the FileExists directory stays the same ie searching the same folder and file for different records. I have a FolderBrowseDialog that I want the user to select the folder first in where to search and then within this chosen folder the static file will be checked. I have this as my folderbrowsedialog:
Dim Browser As New FolderBrowserDialog
Browser.Description = "Please select ."
Browser.ShowNewFolderButton = False
Browser.RootFolder = "c:"
Browser.SelectedPath = "c:windows"
If Browser.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.text.Text = Browser.SelectedPath
End If
I tried adding in this code to the actual file check to encoporated the dynamic folder search but its bringing up errors and not working, I have this:
Dim path As String = "Browser"
Dim f As ReadOnlyCollection(Of String) = My.Computer.FileSystem.GetFiles("test.xlsx")
If My.Computer.FileSystem.FileExists("test.xlsx") Then
Box.Checked() = True

I am having a problem. The IO.Directory.GetFiles code is resulting in error do to the fact that it is trying to access the Temp folder in the Windows folder on drive C:. Apparently that folder is restricted... When the code encounters that folder the code stops retrieving files. Is there a way around this? Is there somewhere i can give my program administrator access? If not then am i able to skip the files in that location?

In general Combo Box looks for the strings in the list that Start with the text that typed in the textbox portion of combo box.
I want a feature in combo box which do not just look in the starting of the strings, insted they shold search the maching strings within any part of records i.e. If User types 'Ja' in textbox portion, the the list should show following maches with highlighting the mached records
Micle Jackson

Similar control is already used by Yahoo Web Site for Search Assistance in its Web Search Combo box. Here if we type say 'bush', it will populate following records
