Searching For A Text String Within A Folder?
May 5, 2010
VS2008
VB.net
I have the following simple code for searching for a text string within a folder and have several questions:
Dim searchFolder As String = "C:BakerOrders estOrders"
Dim files As ReadOnlyCollection(Of String)
files = My.Computer.FileSystem.FindInFiles(searchFolder, "NEXT DAY PM", True,
[Code].....
The folder will contain up to 1,000 text files (at any point) at 20kb to 50kb each. The scan should occur every 5 sec with ~200 new files and (-) ~200 exiting files during this period.
Questions: The previous code only catch files from 1 text string. Is there a way of doing one search and returning the files which contain any of the 3 strings? Is there a more effective way of achieving this? Is there a simple / effective way of searching each file only one time by keep track of previous results while searching only the 200 new additions each scan?

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.

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've got two text files. The first has got a list of certain keywords. Each one if these keywords are fed into a combobox. Now, when I choose one of the items from this combobox, I want to search the other textfile for the same keyword and read from that point to the next keyword. And then feed each line into a listbox. Perhaps I should use an INI-file for this purpose, doesn't really matter for me.
The textfiles have this structure;
Textfile1:
London
Oslo
New York
Hamburg
Amsterdam
The second textfile has this structure;
Textfile2:
'London'
Apples
Oranges
Pears
'Oslo'
Pasta
Salami
Monkeyballs
'New York'
Dada
Duda
Dadadish
Is this possible? The reason I want to do it this way is to create a fully dynamic system. One which relies fully on whatever information is stored in these textfiles. I'm gonna build pretty complex strings from these results later on. So far, I've got this to read the first file and add each line to the combobox:
Dim oReadMenuFunction as System.IO.StreamReader
oReadMenuFunction = IO.File.OpenText("textfile1.txt")
Do While oReadMenuFunction.Peek <> -1
Dim LineIn as String = oReadMenuFunction.ReadLine()
Combobox.Items.Add(LineIn)
Loop

There's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.

I have a program I made that connects to a driver website at a timed interval to check for updates, but there are certain times where a CAPTCHA page comes up - I am trying to have my Timer stop if that page comes up, so I'm not constantly hitting it over and over - This is what I have, but it doesn't fire when the CAPTCHA page comes up:

So I've been using some code to generate directories and such in a custom treeview, but am looking to expand upon this idea. While it's not using recursive functions, and only calls functions when expanding levels, I'm not quite sure how to put some of these together.find a way to just search through all folders on the PC. If the folder contains audio files, that folder is than added to an array (searching a folder for audio files and adding that folder to an array is done). It's just recursivly searching all folders on the PC.Here is the code I've been using for the treeview (I'm not sure if it can be adapted):
Public Function ListAllDrives() As String()
Dim arDrives() As String
arDrives = Directory.GetLogicalDrives()[code].....

I have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.

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 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 have a folder that contains about 100 txt files with information in each file.I'm trying to figure out how to loop through each file in the folder, and add the text to a string.I've pulled this off MSDN's site, but it doesn't seem to read "each" file but just one.
Dim path As String = "c: empMyTest.txt"
' This text is added only once to the file.
If File.Exists(path) = False Then

I got this
If File.Contains(Searchwhat) Then
Countnr = Countnr + 1
VinBox.Items.Add(filename)[code]....
That code works great to search for one string, but how can i search for multiple strings in the file? Lets say that "Searchwhat" looks like "GFR,EPB,IKJ" and if the file i am searching in can find all that in the file it will add the filename to the Pathlistbox.

I have a problem when searching an XML string. The problem is that I can't get it to work. I have a big XML in a string, and I only need 2 values that are each in seperate elements. It is hard to explain so it's best I just show it.This is my XML: (sorry it's very long, but I want it to be complete so my question can be answered properly).
<transactions result="1">
<transaction raisewarning="false" result="1" location="temporary">
<header>
[code]....
For each <transaction> I need the value of <Number> that is in <Header> and the value of <invoicenumber> in <line (id=1)> ... I have colored the elements in my sentence the same as I colored them in my big XML?The number of <transaction>'s can vary for each XML (these are a webservice response).I've been looking for 2 days now, and I can't seem to grasp this XML stuff unfortunately.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.

I know this has been answered before but I am having trouble with it still. I am trying to find if a textbox has an "x" as the first character. I am trying to use the left(string, 1) command as described in a couple other threads to just test the first character on the left but the only left function I can find relates to the left coordinates of the textbox.

I want to search for a specific string within a text file, however instead of hard coding these string values into the system is there any way I can have them within an external file such as a text file and have these values that are to be searched in there and then pull them from there?

I need to accum some data based on whether or not an SSN number appears in the data. I have it in a string, what I need to do is search for a numeric pattern within the string such as:I looked into regex a bit, but I don't have much time to read deep into it (my company needs the program this week) and it seems too complex to grasp in such a short time. What I've came across so far is:
If (rec.address1 Like "###-##-####")
but I don't know if this will filter it out of the string (it can appear with an address attached to it).

I'm sure but can't see the answer. Currently going through a string "DO While Not ts_IN.AtEndOfStream" looking for information. This includes then checking another string (while inside the first) for matching reference point for further data.
So within the first loop, I have a second loop "Do While Not ts_IN2.AtEndOfStream". And looping through that string searching for the reference point.
This works initially, but after awhile don't find anything because it is not going back to the start of ts_IN2 string each time loops on the first section.
