VS 2010 Check If Txt File Lines Contains Certain Text

Jul 1, 2011

I have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

Check Lines In A Text File With Rows In Database?

Mar 19, 2012

I have a text file with some call records in it. Each call record states a line in that text file. And what I want to do is that parsing to database with a 100% success rate. Due to sometimes the SQL connection might get buggy or stop or w/e so it came to my mind that I should make some function or maybe a stored procedure to check whether the requested/selected or whole lines in that text file have been successfully added or not to the database. Let's assume I have 10 lines in a text file called "log.txt" like:

call line 1
call line 2
call line 3
call line 4

[code]....

And assuming that the SQL connection to the database got stuck somehow(buggy) and it stopped inserting those lines to their respectively columns. Let's say it parsed lines from 1-6 and it stopped there, that's where I need the app to tell me that it stopped and continue inserting immediately where it stopped at to the end from 6-10th line. What am I supposed to do? The smoothest way so that the processor doesn't get overwhelmed (in case there are like hundreds of thousands lines). And should it be written in SQL as a stored procedure or written as a function from VB side.Toolkit : Microsoft Visual Studio 2010 Ultimate - VB.Net language & Microsoft SQL Management Studio 2005 - SQL Database.

I am waiting for a confirmation email to arrive within the web browser I am using I do not need to click any buttons to open this mail I just need some help figuring out how I can check whether it has arrived or not I already have the code to find the link and navigate to it (I had to navigate rather then invoke due to it trying to open in a new window outside of web browser and out of my control)

I really am desperate for help on this one I have been reading about loops but cannot seem to find any example which I can use and change to my needs I have done so well in learning up until now and I have really hit a brick wall for something which seems so simple

Get A Bunch Of Lines From A Text File (they Will Be Filenames Eventually) Which Are Split By New Lines And Puts Each One Into An Array?

Jun 22, 2010

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..

Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then

[code]....

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

Read Lines From Text File 1 And Delete Those Lines From Text File 2?

Sep 15, 2009

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

File I/O And Registry :: Deleting Lines In A Sequential Text File?

Mar 22, 2009

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...

That is my record file

Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

Read Certain Lines From Text File

Mar 24, 2011

I have this code now doing and that is creating my chart from data off a text file. The final task I need to be able to do, to complete my program is have a way to select how many days of data to populate my chats with via a Text Box input. I am thinking I will need to read the complete text file first to count how many lines are in it, then what ever is put in the text box it will take that many lines of data from the text file and populate the chart. For this to work correctly it would have to read the lines of the file back wards.(last line of file would be the first line..) e.g. textbox1.text = "7" then the chart would show only the last 7 lines of my data.

I was looking up examples of Counting the lines in the file, I think I am close here...
Dim fso As New FileSystemObject
Dim txt As TextStream
Set txt = fso.OpenTextFile(ReadChart, ForReading)
txt.ReadAll
Textbox2.text & txt.Line & " line(s)."

Removing Lines From A Text File?

I am in the process of developing a VB.net helper application that will combine two text files into one, remove the extra blank lines, do some calculations and spit out a new and improved text file.

My question is: at the beginning of each file is a header row that starts with a "01". How does one go about removing all of the other "01" rows but leave the first header line?

So far, I have succeeded at removing all of the "01" lines, which isn't what I want but hey, I got it to work

Summing Lines In A Text File?

Mar 11, 2010

I am reading a textfile and extracting information from each line. For example string1 and string2. I am then writing these string to a datatable. However, sometimes there will be repeats in string1 and string2. If there are repeated lines I would like to be able to delete the repeating line and add a counter to find the total number of repeating lines. so if a string repeates 3 times I would like there to be a column with a 3 displayed next to the line in my datatable.
