Clearing Output When Input Changes?

Jun 2, 2009

I created a simple calculator. I just graduated with my Bachelors in Software engineerin in March of 2009. I am tryig to get a better understanding of VB.Net. I created a simple practice calculator and would like to know what code needs to be added in the code to clear the output when the user changes the input without adding a clear button as I know how to clear the input and output using a clear button, y working code is pasted below.

[code]
Public Class Calculator 'Form click event handler
Private Sub Add_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

Clearing Needless Text From IRC Server Input

Feb 21, 2011

I'm making a simple IRC client for myself because I really don't see the need for a lot of mIRC's functionality, but I'm having problems cleaning up the input from the server.

Right now, on connect, I'm getting the following:
[16:37] :young.home.net NOTICE AUTH :** Looking up your hostname...
:young.home.net NOTICE AUTH :** Found your hostname
PING :DE7AED31
[16:37] :DE7AED31!nospoof@young.home.net PRIVMSG Logan :VERSION
:young.home.net 451 PING :You have not registered .....

I've read the IRCP (RFC 1459) and I understand the formatting of the server input, but I can't seem to strip out the unwanted stuff... A friend suggested loading the input into an array and deal with each item individually, but I can't seem to make it work. I have tried, but it doesn't seem to make a difference...

Here's my code
Public Function recv() As String
Dim mail As String
Try
Dim Data(4096) As Byte
sock.Receive(Data, 4096, Net.Sockets.SocketFlags.None)
[Code] .....

VS 2008 Input A Value To Output Another?

Oct 19, 2010

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.

Input Output Error Stream?

Oct 30, 2011

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.

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)

Communications :: Input / Output Control Board?

May 30, 2010

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.

Input And Output Command Line Arguements?

Sep 11, 2009

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)

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.

VS 2008 - Use Regex Or An Array To Display Some Output From An Arithmetic Input?

Sep 19, 2009

I've to make a program that reads an arithmetical sentence from a textbox, e.g 12.3*34+4*5-3 and then on another textbox identify and display what is the content of the first textbox, for example taking the last ex:

If I have this input:

12.3*34+4*5-3

The output should look like this:

<number>12.3
<operator> *
<number> 34
<operator> +

[code].....

This program should only read this operators like (+,-,*,/).I'm have in mind 2 ways of doing it, one with regex and the other taking the first sentence, put it on an array, then trim it, and somehow get the values of the array and identify if it is a number or a decimal number and if it's an operator and then display it.

The difficult part or the part that i can't conceptualize is how to implement it with regex (it should be easier with a regex format than storing it on a array).I write a bit of code, I used an array to store and then to print the numbers and I used the split function to separate the math operator, but I dunno how to print the operators and the tags.

vb
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Sentencia As String = TextBox1.Text Dim i As Integer Dim arryTextBox() As String TextBox2.Clear() arryTextBox = Sentencia.Split("+", "-", "*", "/") For i = 0 To UBound(arryTextBox) Dim Array As String = arryTextBox(i)

[code].....

Btw, I also have the code to validate the input on the textbox ::wink::

Save Application Data (input+output) In A New File Format In Program?

May 16, 2011

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.

Input / Output Methods And Validation (for Secure Coding) - Read/Write DB Encryption ?

May 16, 2011

I've been trolling for a long time now and have decided to register as I finally have some time to start jumping into VB. The last time I coded VB, the current version was VB 4. I've been out of programming for a good while now and considered myself a beginner (tutorial example coder haha).

My question is: Where is a good place to start learning VB.NET?

I know it's an often asked and answered question - but let me give you a bit more information so more specialized replies might be given.

I'm in INFOSEC/COMSEC and would like to (eventually) develop a program that contains a DB of information that is read by the application and saves input information into a DB (encrypted) as well. The program will be a 800-53 C&A control assessment program; used for tracking system compliance for federal information systems. I would like to be able to develop such a tool to make my life easier at work instead of using Excel spreadsheets to track everything.

I would like to learn:
- Input / Output methods and validation (for secure coding)
- Read/Write DB Encryption (RSA or other 128-bit) for user input information
- Ability to generate PDF reports from the primary keys and data sets from the above DB

My goal is to create a program that allows a user to install the program, setup a 'master' account that a serial/key has been generated for - that master account is then allowed to create new projects (progress saved in DB). A project asks the user certain questions pertaining to information systems and takes the input and saves it into the DB (encrypted). When the assessment is completed, I would like the program to be able to generate a PDF report from the DB (from a layout template I created).

.net - Why Only Getting One Output Value (and No Debug Output) From This Code?

Jun 14, 2012

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.

Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False

[code]....

Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is

For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next

not giving me a debug output?
