Compare Two Input Files And Extract The Duplicates To One Output File
Dec 31, 2009
so here is my scenario. I have two input files... both are plain text files. File1 has customer name, customer address and invoice number. File2 has customer name, customer address, invoice number AND a keyline. File1 will only contain some of the records in File2, and it will change daily. I need to be able to compare File1 against File2 and output one file (preferably an Excel spreadsheet) with the info from File1 and the keyline from File2, that matches the duplicated info. I know the basics to get it to work, but I'm not sure what would be the easiest way of doing this... File2 can have up to 100,000 records per day. I'd only need to run it once a day though.

Depending on the data being used, I can have up 10,000 items in each of the 2 ListBoxs. I need to find and remove any Duplicates between the 2.I am currently using the method of select and Item from Listbox1 and search in Listbox2. If I find a match, then remove both items. This goes back and forth until all the duplicates have been removed. This take some time.Currently have the code in Old VB6 and VB2008 Express.

This question has been most likely been asked a number of times, but really hitting a brick wall regarding this.
The issue is that at the moment, I have to create a database using text files on VB.
So far I have managed to get the code working to add new customer and browse added records, but stuck on how to output/input back and fore to a text file, to store information, and after this input/output the text file to a DB ( Not worried about this at the moment)
Public Class Customer
Dim CmrColl As New Collection 'Create the new collection. Think of this as an array of objects.
Dim itemCount As Integer = 0 'A variable to help us scroll through the objects later.

I work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.

I have 4 string lists as follows
Dim input_list As New List(Of String) Dim input_POS As New List(Of String) Dim trigger_list As New List(Of String) Dim trigger_POS As New List(Of String)
I want to compare the contents of the input list (containing words (e.g., want, the) etc. to the ones of the trigger list (containign again words) and if a same entry (i.e. word) get the POS for both input word and trigger word from the relevant lists and put them into a property list. For example
input list (want, the, right)trigger list(want, there, wait)input list POS (verb, article, adjective)trigger list POS (verb, pronoun, verb)
Output property list (want:verb, want:verb) (only want is common between input and trigger list). Then I need to conduct a test between the two property items for similarites. If they are exactly the same, the code should output a confirmation "i.e., Yes" into a textbox. If not the code should output a "No" plus the contents of the property list into a textbox.

I have a task to resolve, it is regading extracting characters from a long string to the console, the extracted text shall be reformatted and saved into a CSV file. The string comes out of a database.
It looks something like: UNH+RAM6957+ORDERS:D:96A:UN:EGC103'BGM+38G::ZEW+REQEST6957+9'DTM+Z05:0:805'DTM+137:20100930154
The values are seperated by '.I can query the database and display the string on the console, but now I need to extract the Keyword 'ORDERS' for example, and lets say it's following 5 Characters. So the output should look like: ORDERS:D:96A then I need to extract the keyword 'BGM' and its following five characters so the output should look like: BGM+38G:After extracting all the keywords, the result should be comma seperated and look like:
ORDERS:D:96A,BGM+38G: it should be saved into a CSV file automatically.
I tried already:
'Lookup for containing KeyWords
Dim FoundPosition1 = p_EDI.Contains("ORDERS")
Console.WriteLine(FoundPosition1)
Which gives the starting position of the Keyword.I tried to trim the whole thing around the keyword "DTM". The EDI variable holds the entire string from the Database:
Dim FoundPosition2 = EDI
FoundPosition2 = Trim(Mid(EDI, InStr(EDI, "DTM")))
Console.WriteLine(FoundPosition2)

In my programming class, we have been set a task in which a user inputs 8 numbers, and those 8 numbers will be split into groups of 4 (therefore having 4 lots of two digit numbers). These 2 digit numbers will then translate to a specific time, day, place and city.
For example, this table below is what we have been given for city. (there are separate tables for time, day, place with different 2 digit numbers)
(Excuse the formatting)
City Code
London 11
Paris 37
[Code]...
For example, if a use inputs 11995467 I would want that to output London (being the number 11), [a PLACE = 99], [a DAY = 54], [a TIME= 67]
Bearing in mind I am a newbie, and my knowledge of VB is minimal. How would I go about doing this. It's suggested we use MOD and integer division, but I don't see how it can work.

Applications in the .NET Framework can use the System.Console class to read characters from
and write characters to the console. Data from the console is read from the standard input stream,data to the console is written to the standard output stream, and error data to the console iswritten to the standard error output stream. These streams are automatically associated withthe console when the application starts and are presented as the In, Out, and Error properties, respectively.I am working with redirects and I am solving small problems one at a time. So far so good, but I lost track of the big picture here. Can someone please clarify something for me.

We learned How to assemble an input/output control board that would connect to your serial port. We were able to use out statements (back in the old gwbasic) to send output signals to the parallel port to turn on/off different outputs. The board had connections where you could connect lights, relays, etc, and had connections where you could attach switches and sensors.
I have been looking for something simple that I can manipulate in my programs. I already have an ActiveHome X10 interface which includes an activex for receiving and sending x10 signals (home automation, turning lights on/off, etc.). I want something that I can straight out connect relays to, and sensors as well. I don't want something that connects to the serial port since that is already being used up, the parallel port would work fine, or even better usb.

I have 2 VB programs that I would like to communicate with each other, but I want them to be separate EXEs. Anyway, the easiest way I figured would be for me to call the one program from the other and then return a result. How do I get this result into another program?
Here is how I want it to work:
1. Start System Information Program (easy)
2. Call a video test program, and send a couple arguments (see below)
3. Receive arguments from the video test (I do not know how to do this, I do not know how to send from the video test or receive from the system information)
