I'd like to ask about the way in ASP.NET VB to detect the changes in stocks prices, if the price inceased, the containing cell inside the grid blinks in green, decreased will blinks in red? ex: if the price now 10.00$ and increased to 10.01$ the containing cell will blink with 1 second in green..
View 1 RepliesI'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

I created a program that displays the stocks from a file, with options to add/update/change prices etc. I had it working and I was adding things etc. So I went to erase what I did from the file itself, and now I am getting an IndexOutofRangeException. Is it because I was adding to the array?
Here's my code:

View 1 RepliesI want to do a project in vb.net 2008 using database from MS Access 2007. I have to go from the main menu to the other forms, in each form I have to select one or more items, each item has a price (should be taken from the database *.accdb), then I have to return to the main menu, click the cost button to find the total cost of these items.
1. Where I have to write the code to access my database, in the main menu or in each form individually? and how to write it? I used the code found at:
http:[url]......
but after DEBUGging told me that it cannot see "Table1"?
2. When I am in one of the forms, do I have to "save" my selections, and how?
3. How do I exit from any of the forms to give me the total price to the step, form, I have reached?
4. The total cost should appear in a separate form (screen) at the same time should be saved?
I am trying to use if statements to add the prices of a cruises special packages together. I am using check boxes for the packages, so any, from none to all 3 are able to be checked. The packages available are VIP, excursion and restaurant. The price will also depend on the cruise length (7 or 10 day). I am wondering on which format to use, and if I even need to use if statements, how to make this statement true,

I am trying to put together a simple form with prices assigned to Radio buttons and check boxes.
I started by creating a simple form with four Windows Form control, two check boxes and two radio buttons, there is also a NumberUpDown Control for quantity but I have not added that yet.

I am trying to start as basic as possible then work my way up to more complex calculations as I progress.

View 11 RepliesSweet candy store currently has a special offering of heart shaped candy. It comes in two sizes: small and large. The company sells the large one for $29.50 and the small for $16.25.Design an application to calculate how much a costumer owes. When the user clicks the "Calculate" button, the program gets the number of large and small chocolate hearts ordered from the textboxes, calculates and displays the extended price for each type of the chocolate in a label. The program also calculates the weight of the chocolate to determine the shipping cost, displays the total weight, the shipping cost and the final total due. The large chocolate weighs 4 pounds 10 ounces, and the small one weighs 2 pounds 14 ounces. Shipping cost is 35 cents per pound and 3 cents for each additional ounce. Display all dollar amounts except the final total due with 2 decimal places. Display the FINAL TOTAL DUE with a leading dollar sign and 2 decimal places. Be sure to also include a CLEAR button that will remove all inputs/outputs from the form, and an EXIT button. Define the CALCULATE button as the accept button and the EXIT button as the cancel button.

Im trying to make it so I can input a number for a percentage, multiply that with my current array prices, and display the total in the listbox. I have a few theories on why it isnt working but cant pinpoint which one to use, I'm at a basic level to this and still learning the process. Im also pretty sure I dont have everything I need on here yet.

This is not a problem, as my code works correctly, but a question of aesthetics. I have written a programme which compares the prices and terms of up to 10 Bidders and 500 line items in mixed currencies. For this small section of the programme, I paraphrased a jmcilhinney CodeBank example; his looked neat, mine looks ugly.
