View 6 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.
View 4 RepliesI am using Visual Studios 2008. I'm trying to make a basic addition calculator. It consists of 2 input text boxes, 1 output box and one button. Below is the code I have which works, however, instead of just displaying the answer, I want it to display the entire arithmetic problem including the answer. For example. Instead of just giving me the answer of "6" in the output text box, I want it to say "3 + 3 = 6".
Here is the code I have so far.

I'm trying to generate a simple average pace calculator. I have coded the calculator to a stage where it seems to work although on testing it i have noted my average pace rounding seems to vary slightly from others online. Although i have also note different calculators online seem to vary from each other.
I have used the .tostring("0.##") as a means of converting my calculation back to actual time rather than a decimal. Is this the correct method or is there a better way?

I have a small project from my university they have asked us to make a calculator , well everything is easy so far except the 3 last functions that I need help with.
as we all know vb has already some math functions implemented in its libraries the problem here those functions giving me wrong results I am trying to get math.tan(lblnum.text) math.sin(lblnum.text) and math.cos(lblnum.text)
they don't output the correct numbers any idea why?
just Addition only at this time each number 0 to 9 have this code[code].....here what he says..Write the code for the equals button. There's only three lines in total, and here's a little help.
You need to use the other variable that was set up at the top of the coding window, total2. The variable total1 will be added to whatever is total2.The first line of code will be this
total2 = total1 + (something missing here)
Your job is to supply the missing code. In other words, replace "(something missing here)"
Remember that total1 contains the first number to be added. And you know where that came from. The only thing left to do is to add the second number.For the second line of code, you need to transfer the total2 variable to the textbox.For the third line of code, all you are doing is resetting the variable total1 to zero. That's because after the equals button has been pressed, we have finished adding up. If you wanted to do some more adding up, that total1 will still hold the value from the last time. If you reset it to zero, you can start adding some new numbers.
I was trying to make a calculator which takes the amont of copies you want to make and it tells you the cost. Then you type in the amount you want to enter and if its less a message box comes up saying "please enter more money". I've had a few problems
1. when i use formatcurrency the program crashes for no apparent reason
2. if i calculate cost without entering any copies then it crashes (ive tried putting a msgbox in but it crashes anyway)
3. if i get the msgbox to come up saying "Please enter more money" i had to remove the formatcorrency tag.
Do visual basic forms each run in separate memory and if not is there a way that I can force them to do so. I want them to be in separate memory so that if one form freezes the entire program won't.

View 21 RepliesI am creating a VB 2008 change calculator as an assignment. The program is to use the amount paid - the amount due to calculate the total.(this is working fine). After that, it is to break that amount down into dollars, quarters, dimes, nickels, and pennies. The problem I am having is that sometimes the quantity of pennies, nickels or dimes will be a negative number. For example $2.99 = 3 Dollars and -1 Pennies.

Ok. I just took my final for VB and the last chapter we did was on procedures and functions. Functions was the only thing out of this whole semester that I was just completely lost. I'm trying to work on this cause I'm taking Advanced VB next so I wanna know what I'm doing. So I'm trying another tutorial in the book and I'm really lost. Here is what the it wants you to do.
Retail Price Calculator
Write an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item's wholesale cost is $5 and its retail price is $10, then the markup is 100%)
The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item.
When the user clicks the Get Retail button, the program should do the following:Verify that the values entered by the user for the wholesale cost and the markup percent are numeric and not negative. Call the CalculateRetail function Display the retail cost as returned from the function.
Here's what the calculator looks like and my code so far.

I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test.
The calculator can do one of two things:
1 - given an existing network and CIDR(mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.
2 - given an existing network and CIDR(mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.
I am making a calculator at the moment and the plus works and so does the minus well the minus does the FIRST time but not the time after that.you would normaly get 2, but instead it says that the answer is -3.I have attached the calculator so that you can have a look.
