Visual Basic :: Searching For String In Text File

Searching A Text File For A String
Hi,

What is the quickest way to find out if a text file contains a specified string?

I have a program that adds a string into HTML files. I do not want to add the string if it already exists in the file. I am processing upto 50 files at a go. (I am reading the file line by line until I find the right spot for the string.) Is it possible to read in the whole file in one go into one string and then do an instr command?...or something.

Thanks for any advice.

Searching And Deleteing String In Text File
i am useing this code to delete a line # in a text file:

Open "C:windowssystempersonnel.txt" For Input As #1
Open "C:windowssystempersonnel1.txt" For Append As #2
Do While Not EOF(1)
Input #1, LineStr
Line = Line + 1
If (Line <> linedel + 1) And (Line <> linedel) Then

Write #2, LineStr
Else
'Ignore the line
End If

Loop

Close #2
Close #1

Kill "c:windowssystempersonnel.txt"
Name "C:windowssystempersonnel1.txt" As "C:windowssystempersonnel.txt"
my question is i have alot of chkboxes in array and is it possible to delete a text line by searching for the words that you want to delete instede of the line number?

Searching For A String In A Text File Line By Line
eiSecure: The following code will work with single instances of the ~BEGIN and ~END tags, but it doesn't work with multiple instances (but you should be able to add it in if you play around with it for a bit).

VB Code:
Dim sFile As StringDim saFile() As StringDim strText As String Open "MyFile.txt" For Input As #1sFile = Input(LOF(1), 1)Close #1 saFile = Split(sFile, vbCrLf) For y = 0 To UBound(saFile) If Trim$(saFile(y)) = "~BEGIN" Then For x = y To UBound(saFile) If Trim$(saFile(x)) = "~END" Then For Z = y + 1 To x - 1 strText = strText & saFile(Z) & vbCrLf Next Z strText = strText & vbCrLf End If Next x End IfNext y Text1 = strText

Searching For A Directory Vs Searching A Text File For The Same Thing!
After working on a piece of code for a while, and actually getting it to work, I was asked to do it a different way.

Originally, I had a login box set up to search for a user's username and password that was stored in a text file. The problem with this was that I didn't know how to get it to search ALL of the entries, not just a set 1 to 10 like I was using in my code. To see the full program code, click here.

Now my group members want me to do it so that it searches for the directory instead of the text file for the same information. The directory name is the username, and in the directory, they'd like (theoretically speaking) to have the user's username and pass stored in a pwd file or a txt file.

I'm trying to argue that searching a text file's easier (partly because I believe it is, and also because I've already done it), but they're arguing that searching the directory's easier because then, the program could just store the directory in a global module, so when it comes to other aspects of the program itself, it'd be easier to do.

I'm willing to give the 'searching for the directory' route a try, but I can't seem to find anything that pertains to this, WITHOUT using api (I've searched the forum, and all I found was recursive search for stuff thats already in a directory, or stuff that has to do with api).

Any help would be greatly appreciated.

Searching A String Of Text
How do I search a string of text to see if another string is in it.

For example, the long string would be...."Hello World." and I want to know if "Hello" exists there. I'm sure this is easy and I should know this, but I can't figure it out. Thanks

Searching For Text In String Problem
Hey,
I'm trying to test to see if a string contains a certian word but I'm not having the best results.

I'm using:

text = "This is a string"
word = "ring"

If Results <> 0 Then

msgbox "Word Found!"

Else

msgbox "Word Not Found!"

End If

But it doesn't match. How can I do the same thing but be able to match words inside of words?

Thanks,

Searching For The First Instance Of A String In A File. *RESOLVED*
I'm writing a piece of code that searches for the first instance of a string in a file, and return the offset in which the string is located. So far I have this:
VB Code:

...but I'm not satisfied with the speed. Is there any way to speed it up? Better yet, can anyone suggest a better method of achieving this?

Searching Text File For A Group Of Text.
Does anyone know the most efficient way to search a text file for a group of lines? For example, if the file was:

d = xxxxxx
a = xxxxxx
b = xxxxxx
d = xxxxxx
c = xxxxxx
e = xxxxxx
b = xxxxxx
where xxxxxx is any set of numbers.

and you wanted to search for the block of strings:

b = xxxxxx
d = xxxxxx
c = xxxxxx

Is there a quick and efficient way beside reading each line, matching against the first line, checking if the line following it is the second line, etc?

TIA

Searching A Text File
I am writing a small program to screen pop our ACT! Database from our CTI program, I have tried using a method that searches the database using the SDK tools but it is too slow.

Another utility creates a CSV from the database which is used for another purpose but the CSV contains the phone numbers and the unique ID of each record and with the Unique ID i can tap straight into the database very quickly.

The CSV File containing about 8000 lines each with 8 fields, I would like to search in the file for the appearance of the phone number and then use the contents of field 8(Unique ID) further in the program. The phone number could appear in multiple lines and i would like to have it display a choice between these records.

I Am a newbie coder so any help with methods of searching this CSV would be greatly appreciated. Search speed is the key feature i need.

Please Help

Searching Through A Text File
I would like to be able to extract certain data from a text file for my program and have no idea how to do it. I've searched through all my VB books but I'm still confused.
Here's the scenario.

The external txt file contains comma delimited data that would look something like this:

Amount,11000,Amount,5000,Amount,1000,Amount,11000

The real thing contains more data, but the above is more specific to my needs.

I would like to set it up where the user would click a button, the program would go through this file (located in the root of the c: drive) and add up all of those amounts. Then return the total to a txt box.

I know this is a bit much, but any ideas would help.
Thanks!

Searching A Text File...
I created a database to store records and had no problem returning query results. However, I was told that we can't use Access and that the records need to be stored in a semi-colon delimited text file.

I have no clue whatsoever how to write a search. This file holds over 260,000 records so speed is possibly going to be a problem.

The file format is (semi-colon used because of name Format with comma):

ID; Lastname, FirstName; Sex; Date of Birth; Mother's Name

Originally with the database I selected a field to search and ran the related query with the criteria pulled from a text box. Now I'm thinking that I just need a text box and run the search for matches from that single text box.

A piece of code to get me started would be lovely. Or... if you have links to any tutorials that would be great to.

Thanks,

Phil

I am doing my a level visual basic project, and have a problem. My program is for a shoe shop, with a stock control system and a till system. I add the details of a shoe (barcode, name, price) into a text file from my stock control system, and in my till system i want to input a certain barcode, where it will search for this barcode in the saved text file until it finds the corresponding record, and as a result brings the corresponding name and price of the shoe onto the screen. How do i do this? Do i need to separate each individual variable (barcode, name, price) by a comma? because when i open the text file it is stored like so: "Slipper 49.99 34583248 Ross † 12365478" (These are two records, the "slipper" and "ross" are the names of the shoe, the 8 digit nos are the barcodes, and the other symbols are the price and quantity (?)) btw, i also need it to take one off the quantity each time i input the barcode (this is when a sale is made). Help would be much appreciated. Thanks, ross

Hello all,

am trying to have a list of about 60,000 words(.txt file) searched and the results/partial match displayed in a text box. It will be used as a spelling reference for specialty words. I know that a list or combo box would do what I am looking for but populating it with that many entries would be a nightmare. Any ideas as to how I could accomplish this? I have tried to populate a table with the text file in a VCE form but it crashes the PPC and requires a hard reset. Any help/direction would be appreciated.

Reading/Searching Text File
I tried searching the boards for the answer to this, but all i could find is bits and pieces. All I need is some simple code on how to read from a text file, and how to search through a text file, then take the items its found, and place them into variables.

For example

I have a text file called text.txt. The contents of the text file are as follows:

One
Two Three
Four Five Six

Basically what would be the code to pick out the string "Four Five" from the text file and place it into a variable. It would need to search through the entire file, to see if there are several instances of "Four Five".

Im sure this has been answered several times, but I couldnt find it

Searching And Modifying A Text File
OK, this is a pretty basic thing, and if search was working, I would probably find the answer in there. So bear with me, I know this has probably been covered a million times.

I'm writing a program that reads a text file, which is basically a bunch of records, displays them, allows the user to edit them, and saves the changes back in the file. (Obviously, this thing would be accomplished so much better with a database, especially since we're looking at uber files on the order of 1+ MB. But the file is already in text format so that's what I have to work with.)

So, my question is, I haven't done file handling in quite a while, and I'm not sure what the best way to go is. I was thinking about using the FileSystemObject to find and manipulate the file, then I thought about using the Word ojects, since it has find capabilities built in. I'm not that familiar with either of these objects, so I don't really know if one is better than the other, or if there's a better solution. If anyone can give me some tips, or point me to some info, I'd appreciate it.

Thanks.
