Search Txt File For Keywords?
Nov 22, 2009
How would I make a program that would search through a .txt file, and find certain predetermined keywords. Basically, I have a very simple keylogger on my son's laptop to keep an eye on him. My hope is that I would make a program that would go through the .txt file, and if one of the keywords is found, then I would have the program execute a little something I have cooked up to warn to stop. The only problem is, I do not know how to search through the .txt file.

Hi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?

I am in the process of creating a program, using Visual Basic Express, for a physics professor who has recently had to rename all 1500 questions for his course. I created a database that has the old names, new names, and the entire contents of each question. The program seemed an easy enough idea, but has proved to be very difficult for me. I am new to programming (this is only my third go at it) and have searched for an answer to my problem for at least 20 hours, and have yet to find anything that will work for what I need.
What I would like is to have a text box in which he can type in a keyword (such as "Sun", "ISS", "Force", etc) and for the program to search throughout the entire "questioncontents" column and pull out any questions that contain those words into the datagrid. As of yet the closest I have gotten is for it to search the first word of the column, which is not very useful since most of them start with "The". I had also thought of creating several keyword columns and then just having it search through those, but I couldn't figure out how to apply the filter to multiple columns.

How can I exclude a common keyword like "a,the,is,or.. etc.." from my search query ? If you do a search in Google or other search engine it says "the" is a very common word, and was not included in your search.Is there a list somewhere that I can get all the common keywords that need to be excluded from the search query?

I'm making a (F1) part for my application. I made a form with a Webbrowser-control and I made several .html files. Now I would like that the users enter a keyword and that they see all the files where that keyword is found in the metatag <keyword>. What is the best (and fastest) way to search for that?

I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:
(e.g.) "24 results found for 'blue sky clouds' "
...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.If no results are found I would like the label to display:(e.g.) "No results were found that match your selection. Please try again"I would also like the label to be invisible until a search occurs.

I am trying to make a simple program that will have three texbox controls and it will have like a paragraph in textbox2 and I want to have key words that I type in TextBox1 and it will match the words from textbox1 and will find a line with the matching words. It will then show that sentence from TextBox2 in TextBox3.
This is what I have so far but cant seen to get it to work:
Dim search As String = txtSearch.Text
If txtMain.Contains(search As System.Windows.Forms.Control) Then
MessageBox.Show("Connection Activated")
End If

With this code I can see what happening I'm just showing you what've I've done so far. Basically I want to use an If statement to see if an active directory object contains one of the keywords found in an INI file. I was wondering is this possible with just an IF statement or do I have to use a loop or a for each and how would I do that using one of those two

How do I edit JPG File Title, Subject, Comments, and Tags/Keyowrds?The Exif information provided was helpful, but in the end did not actually solve the real riddle I was working on. So I'll take another angle at describing the desired result:
I want my VB.NET app to allow me to edit the following details of a Jfile (see image):
Title, Subject, Comments, and Tags/Keyowrds
I had a handy image to include but not enough points to post it. Weak.
RIGHT CLICK A .JPG IN WINDOWS and select PROPERTIES
Win XP: Select the "Summary Tab" and Look at the "Description" group
Win7/Server 2008R2: "Details Tab" and look at "Description" group
how to edit those fields through VB.net in Visual Studio?
EDIT: The ultimate goal is to use the image viewer/editer that I built, to sort thousands of images of random webjunk I have collected over the years.Upon viewing the image (say "00001.jpg") and figureing out what it is ("ceiling cat sends son" picture of a lol cat), I want to type in the description (already done in the form). When I hit enter I want to rename the file (from "00001.jpg" to "ceiling-cat-sends-son.jpg", then fill in the keywords, title, subject, and comments fields with the same data: "ceiling cat sends son".
local indexing and with my (later) automating a SQL server referential database for use with site wide searches on my website. The ONLY thing I can't seem to figure out is how to modify those four fields as if I had right-clicked the file and added the keywords.

I am building a program that strips out certain keywords from a much larger file. I am using code that .paul. provided in a different post, but I can't get it to work correctly. Here is the code that I am using: [code] Basically, the first match will appear in textbox2, but no other matches appear after that. I put a breakpoint at the For Each loop and checked out the locals. I am showing 2,502 matches for the variable "match." I just now put another breakpoint in there and I can see that it is stepping, but nothing is recorded.In the archive is a file named debout.txt. This file should be used for the testing.

I'm creating a search function to search through a binary file and find a record based on the users input. Surprisingly, that isn't the problem! The problem I'm having is that as part of this I'm using a procedure to display results in text boxes, and I'm getting the error "Too many arguments to private sub display customer"I've encountered this error before, but never really knew what it was... Here is my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
FilenameCust = "F:\College\CustomersFile.bin"

In VB.NET, you can surround a variable name with brackets and use keywords as variable names, like this:
Dim [goto] As String = ""
Is there a C# equivlent to doing this?

I have a question here. I'd like to develop a vb.net program to run thru all source code in a folder to look for certain strings.my initial thought is to create an .ini file then program will read the strings then start searching in the source code for the strings entered.
the final output will be an excel sheet, stating the filename and the line number.
is this a good way to do it? if yes, can i ask for a skeleton program?if no, any other way?

i'm used to be a VB6 user and started move on to VB.NET few days ago and i'm still quite new to its new syntax.Today i came across there is a object declaration with the 'Nothing' keyword follows at the end and what it actually means? Dim l_Active As AvsIdentityType = Nothing
As i know Nothing keyword is usually used to release the instance to the object after we used it but why it is used in the declaration statement?BTW, the 'AvsIdentityType' is a public structure.

I'm attempting to recreate a form in Crystal Reports, under VS2010, after a form created under VS2008 stopped working.I have reached a point where I am trying to copy the following function from the old form to the new:
Shared myVariable As String
myVariable = {myTable.myColumnName}
formula = ""
In the original function editor, the words "Shared" "As String" and "formula" are highlighted in blue as keywords.In my new version of the report, only "Shared" is highlighted as a keyword. When I try and save the function, I am told it contains an error. This error is reported as: "A variable type (for example, 'numberVar') is missing."
The formula works on the original formula workshop. Why not now?

I'm trying to execute an sql statement in vb.net to an Access database, I am escaping the reserverd word using square brackets []. This has worked in all my SELECT statements within the program.
The reserved word is level
But the SQL statement below fails saying
Syntax error in INSERT INTO statement.
If I directly copy the statement and execute this in Access it works fine
datalayer.getDataTable(String.Format("INSERT INTO users (username, password, [level]) VALUES ({0}, {1}, {2})", username, password, level))
The above statement works if I remove [level] and replace this with another column name.

If someone types in something like "red", I'd like the word's font color to become red. I tried something like this:
Dim red As String = "red"
Dim fnt As Font = New Font("Microsoft Sans Serif", 8.25)
If RichTextBox1.Find(red) > 0 Then
For Each _str In RichTextBox1.Text
Dim my1stPosition As Integer = RichTextBox1.Find(red)
RichTextBox1.SelectionStart = my1stPosition
But I dislike the highlighting-type approach.
