Reading File - Search Files For Matches And Depending On What Category The Match Is Under
Feb 14, 2010
I'm trying to search files for matches, and depending on what catagory the match is under, do a certain function... Say I have a .txt file that looks like this
[Code]...
Then I have a form with Button1 and Textbox1. Say I type "Cat" into Textbox1 and press Button1. It would then bring up a MsgBox that says "Match found under Animal catagory". But if I put "Three" in Textbox1, the messagebox would say "Found under Numbers catagory".

I can't seem to figure out how to write this query properly. I've tried various combinations but nothing's worked yet.Below is the relevant portion of my database model:
I need to select the products that match a given Category and Group, and that match a given Year, Make, Model, submodel. This I've done below: ItemList = From P In gDataContext.Products.Include("Groups").Include("Groups.Category1").Include("LookupYearMakeModels") From G In P.Groups Where G.Category = Cat And G.Grp = Group From Y In P.LookupYearMakeModels Where Y.Year = YMM.Year And Y.Make = YMM.Make And Y.Model = YMM.Model And Y.Submodel = YMM.Submodel Select P

i'm currently making a client database program for work that stores data in multiple text files (so that the information won't be confused as to which info belongs to who in the database). Each client has his/her own text file, which isn't really a problem although i realize it's a bit messy. A listbox holds items, each item a person's name.When the listbox selected index is changed, the streamreader opens the corresponding textfile, which is as such: "John Doe.txt", and populates the correct textboxes with the information stored in "John Doe.txt".What I'm unfamiliar with is implementing a search function.
1. search query entered
2. streamreader reads through all txt files in a directory looking for matching keywords.
3. if a match is found in a txt file, it looks at the name ("John Doe.txt"), gets the corresponding listboxitem, and finally, once the textboxes have been populated with the info in the file, highlights the matching keywords.
4. then i figured if there was more than 1 match over more than 1 txt file, you could repeat the process and skip to the next match via the tab key (like the find feature of a WebBrowser or other such application).
What i don't understand is how to read multiple text files, search in keywords, highlight the matching keywords, or the tab function..I know that's a lot to ask on a forum, but I had nowhere else to turn.

'this calls the connection sub
connection()
SQL = "SELECT * FROM Customers WHERE Surname Like '" & Textbox1.Text & "%'"
'this calls the DatagridFill sub
Datagridfill()
This is my current code, it searches for anything entered into the textbox against the row "surname", but I also have a first name row and a Order ID row. Instead of searching against one row, i want to to search all the rows, and fill the datagrid with anything it matches it with.

I'm trying to gather some WMI data, search that data and depending on the results change the color of a textbox and append some text.I can acheive this using a select statement but was hoping there is a more elegant solution as what I have generates a lot of similar code At the moment, the WMI data contains two properties I'm interested "State" and "ReplicatedFolderName". The"State" value determines the color and text that goes in the text box, however there are different textboxes for each replicated folder name.What I have which works is

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

An application that my company uses stores report files with a .dat extension for use with their software. These files can be opened in notepad and the basic report information can be seen as text. I am attempting to write an app that opens and reads data from these .dat files and displays it in a checked listbox. My hangup thus far is that I can't figure out how to read the data from the .dat files since they are not .txt files. Can anyone point me in the right direction?

Here's the situation: I've got a form that has
- RichTextBox
- OpenButton (to load RTF file)
- SaveButton (to save RTF file after editing)
- Textbox (for search phrase)
- SearchButton
- ExitButton
- 2 RadioButtons (WholeWord and MatchCase search)
All of them are working just the way I want them to except search features; I don't know how to write them properly. At the moment, they search and highlight only the first word they encounter. E.g. say I search for word "the" in the document, only the first "the" it encounters is highlighted. The rest is just untouched.
I understand this is because I've only got few lines of simple code as follows
If rtfText.Find(txtSearch.Text, RichTextBoxFinds.WholeWord) = -1 Then
MessageBox.Show("No results returned. Please try again.", "No matching results.", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
I did try a few other snippets I found on the Internet including While loop but they didn't work as I wanted them to, and I couldn't understand them either. What I want is, which ever search option is used, when the matching result is found; it will highlight that word and when I click it again it will move onto another word. If I keep clicking, it will highlight the same words (but located in different areas) throughout the whole document and at the end, it will send back to the first matching word. Just like Adobe Reader search.

I'm creating a search application that needs to have a fuzzy search. Basically if there are 0 results, I need to provide a suggestion, much like google. For example, if I type "Californea", I need my program to suggest "California" after doing a query on my DB for similarity.

I wrote a cleanup program to go through some directories and delete files based on if the creation date is older than say 6 months. It works fine with some of the directories I have that contain around a few thousand small files. However, there is one directory (that contains small backup files from another program) that is loaded with over 300,000 files and it locks up on me as soon as I read in the first file in that directory.I am convinced it is the directory has too many files in it to open it. The server that the directory is on is slow. It takes a half hour to open the directory while on the server itself. I know it will take forever to delete the amount of files I want to delete, but I don't understand why it gets stuck and hangs there with no error message.Here is where I get stuck. Listbox1 is the directory I'm attempting to access
For Each selectFile In My.Computer.FileSystem.GetFiles(ListBox1.Items.Item(Count), FileIO.SearchOption.SearchTopLevelOnly, "*.*")
compFile = Path.GetFileName(selectFile)

The functions will make a direcotry tree in my debug window, that looks something like this:

What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?
