How To Recognize Time Past

Sep 1, 2009

How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this:
Imports System.Globalization
Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick
Dim date_info As DateTimeFormatInfo = _
CultureInfo.CurrentCulture.DateTimeFormat()
ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern)
End Sub

That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
TextBox48.Text = Val(ToolStripLabel1.Text)
End Sub

Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable:
My.settings.12hourspassed

So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1
If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1"
End Sub

The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...

I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off?

How To Recognize Which Item To Display For Each User

Jan 29, 2012

I need to create a program, and now I want some advice from you, as I simply don't have so much experience to get round it.Firstly, I have issue with a checked list box. For example, there will be 5 items.I want each item to have a different value, because it will be a things people will be buying, and so when someone clicks on item1, the value I assigned to it will be output into a label, so user will know how much that item costs. I know how to output it, label1.text = CheckedList Box1.SelectedIndex but how do I set for example for item1 value of 5000, for item2 3500 and etc? Secondly, I will have a page for users, where they will see history of their bought items. But what's the best way to store the price they paid, item they bought and date? It should be able display for each user their own bought item history.I hope you understand what I meant, as I'm quite new in programming so It was a bit hard for me to express what exactly I want. If you didn't understand something, or need more information please ask me. I hope someone will be able to help me, as I really have a bit of a struggle with it. At first I wanted to use plain .txt file to store and output into textboxes, but it wouldn't be aligned, look nice and etc. Then I thought about database, but how to recognize which item to display for each user and etc.

Recognize Handwriting(numbers Only) In A Picture?

Jan 18, 2010

I am trying to create a program that will be able to recognize handwritten numbers in a picture. Right now, the program locates a rectangle that the numbers are in. The numbers will generally be in the range between 0 and 9000. I have found some stuff about ink recognition, but I dont think that is the same. Also, is there anyway to be able to make the program 'learn' from the style of the handwriting? I'm using VB.net 2008

Using XAudio2 To Recognize Pitch From Microphone?

Apr 3, 2011

I'm learning to play the Trumpet and thought it would be a great idea to write myself a flash card type program that would flash a note, pick up the sound from the microphone, determine the pitch, compare it to the note and evaluate right/wrong. For example, it puts a middle C on the screen, listens for a tone above the din and beeps or buzzes if the result is right or wrong.
