Search A Text File (*.txt Extension) For A Certain Keyword?
Jul 22, 2010
I want to search a text file (*.txt extension) for a certain keyword or a part of it. And then let the found item be displayed in a listbox or something else. Now the more difficult part, how can I display the word in front of that found word ?
Example:
I search for VBFORUMS in a file called test.txt
I find this:
VBFORUMS
but in front of that is this:
IDS_IDS_TXT_008912VBFORUMS
How can I then display the IDS_IDS_TXT_008912 on a label ?

i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo
[code]......
However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.

I am wondering, would it be easy to make a program to:1. Activate Window2. Search for a sentence on the webpage.3. Search for a keyword in the sentence.4. Execute action based off the keyword.5. Repeat every 17 minutes.Is it possible?I have used AHK, but I like the interface of VB better. Any insight?Also, I created a whole browser aspect through Visual Basic. Or would this be easier to just run through a program instead of my own created web browser?

I am trying to search one column (Titles) of an Access database using an SQL query. The search entry comes from a split string passed to an array and inserted into the SQL command.
This works well, however, the results I get back are for entries containing EITHER of the keywords entered, not entries containing ALL keywords entered.
The code I am using is::::
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
dgvSearch.Visible = True
[Code]....
The loop is working, but acting as a new search as opposed to searching the results of the previous search.

i need to search any text in my entire database and get the result in my dataset. my database is in ms-access. i have written the following function for the same:
Dim con As OleDbConnection
Dim ada As OleDbDataAdapter
Dim ds As DataSet
[Code].....
the query written herein works fine if you copy and run it in access so i guess it is correct.

I want to build an application using VB, that is essentially an information system.The operation of this system would be as follows:1. User can select one of several buttons, each button being a different topic.2. When a button is selected, information about that topic appears on the right hand side of the form.3. The system allows information to be added by a user So, for example, if a user clicked on the button named 'Banana', information about the banana would appear on the form, where the user could read this info, scroll down etc.I would also like the user to be able to search a specific word like 'apple' and for information on the apple to appear.How could I implement this? I don't know how I would store paragraphs of information, and then search for it based on a keyword.

The user inputs a serial number in a form, the program searches a specified text file on the internet for that serial number, and if it is there then the program runs normally, but if not it exits. I already know how to do the trial part of this program and I know that this is not secure as someone could just hack it and find the text file and read the numbers, however this is for school and is not commercial. The only thing I need to know is how to search a text file for exact text that has been inputted by the user. I've been trawling the internet and I've heard of something called instr or something, but I'm not sure.

Trying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??

I got some code that im try to make search and text file and replace it. The code im using to replace it with is whatever the user entered in txtURL.text. Here is what i have
Dim strFile as String
Dim result as String
strFile = "C:\test.txt"
oRead = IO.File.OpenText(strFile)
result = Replace(oRead.ReadToEnd(), txtURL.text, "1F.php")
oRead.Close()
Is this writing it back to the file also....I think that might be the problem, not sure..
