View 2 Replies"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?

so i added a service based database in my visual basic project. At this time the project only exists of logging in or registering, after which you'll log in.now all my SQL seems to be correct and working, the code is good, but when i register new user, it doesn't get stored in the database. but it does get stored...
i know sounds weird right, well what i mean is that apparently the data is getting stored somewhere because i check whether or not the username exists already. if it does i get a message box. Now the weird thing is that between builds and runs it remembers all the users i registered, but when i close the program and later re-open it, all the data is gone...
i used parameters to insert the date, everything from code below:
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click

i have an access 2007 database in wich i have a table named abc_PersonalLog, wich also has three columns: Id (auto number), StarDate (text) and LogEntry (Memo). It is a Diary application. So, when the user makes a log entry, the StarDate column receives a string formed of concatenated year, month and day, i.e. if date is 20th march 2012, the string will be 120320, and the Log entry column, the text entered by user in a textbox.My problem is that, somehow, i have to retrieve that data, when the user will want to read log entries he made. I managed to assign the text property of a label to the LogEntry text for a given date.But, if the user makes multiple entries in a single day, the table will have several rows containing the same string in the StarDate field, but different text in the LogEntry fields. How can i display ALL the LogEntry texts for all the rows containing the same StarDate value? Here is my code so far:

I am trying to take a database with multiple entries of 11 digit numbers and run a check sum algorithm that adds the 12th digit to the 11 digits as an output.The algorithm is as follows:
Add sum of odd digits starting with first digit, then multiply by 3.
Add sum of even digits, then add to result of odd digits multiplied by 3.
Take result and divide by 10. The remainder is the check sum which needs to be added to the end of the original 11 digits.
I have 7 textbox entries and I would like to add them to a listbox and when I close my application it would save them, I have the code for the 7 texboxes and everything like that has been done, but I just dont know how to add multiple textboxs to a listbox then save the list box so when I close the application and reopen it, itll still be there. I know I need a button to add the list to the listbox, but how do I save them, so theyll still be there?

I have data entries in my database that have a common field. For example:
account_id type user_id
1 new 1
2 old 3
3 new 1
4 old 1
I am using a query like this(mysql): SELECT account_id, type, user_id FROM table WHERE user_id = 1
This is just all theoretical. The problem that I am having with this is it is only returning the first result in this case account_id 1. How can I get it to find all the results with the user_id 1 because in the way I am thinking that it is failing is that it is finding only the first result and then ending?
I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box

In class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic.

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
View 1 RepliesI work for a company that produces accident reconstruction software. We have a vehicle dynamics program that realistically simulates the motion of a vehicle (position and rotation of car and steer angle of individual wheels, etc).
All the positions of the car are stored into an array called AMTN. The vehicle dynamics program can calculate positions at time steps finer than .005 secs (200 FPS).
I need to represent this data in real time, and so far I have not been able to accomplish this. I have tried doing this in Excel/VBA, VB6, and am currently trying to do it in VB.NET.
I have used a whole plethora of timers and counters as well as different methods of drawing lines on graphics linked to images linked to picture boxes, etc. My animation program writes/clears the screen correctly, but there is clearly some sort of lag in either the timer or writing method. I have scaled it down to 25 FPS and there is still a lag.
Here is an example of what I am trying to do with each tick of the timer:
Code:
Sub Timer1_Tick1(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
MyGraphic.Clear(Color.White)
[Code].....
With each tick of the timer, the graphic is cleared, lines representing each side of the car are drawn onto the graphic, and the picturebox is then assigned to the image, which is linked to the graphic. This is just like how your asteroids program works.
Do I need to change my method? Should I use sprites? Or would it be better for me to create images/bitmaps of the animation beforehand and simply flip through them with a timer?
I'm thinking that creating the images beforehand might work because I do not have to calculate the vehicle's position as it is predetermined by my AMTN matrix.
if there is a more efficient way of displaying my vehicle on the screen that would allow for greater FPS, etc.

building a program at the moment that changes registry entries to turn on and change, and off proxy settings. This small program is going to be dropped on each persons desktop so they can easily turn on the proxy in work, and turn it off when they take their laptop home.
However, the proxy address changes depending on which company I am at. I would like to be able to make a single program, but have a "hidden" setting to change the proxy and store it in the program, and push a copy of the file out across the network to each machine. I tried to make it so the proxy address can be saved as a string in My.Settings, but it would have to be made as a User setting rather than an application setting to give it read-write access.The only other option I can think of is to hard-code the proxy address into the program, which really isn't ideal

I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String. Being a setting with an unchangable 'Application' scope i cannot change its value at runtime.
The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ?
