Create An Application That Calculates Body Mass Index?
Nov 10, 2009
I am working in Visual Basic 2008 and am trying to create an application that calculates body mass index. I have the entire form complete as well as much of the source code, but I am having trouble creating the code for input validation. On the form I have a text box for entering weight and a text box for entering height, which are both used to calculate the body mass index. Therefore, both text boxes input information cannot be negative or an illegal character ( $, @, !...) The input validation is supposed to present a Message Box that displays something along the lines of "Please enter numeric values" when input values are illegal characters "Please enter a positive number" when input values are negative "Invalid Entry" when input values equal 0
Here is my code:
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click

Create an application that calculates the total cost of a stay in a hotel in the North Carolina mountains. The application should accept the following in terms of input:Month of Check in Length of Stay (in Nights) Number of Persons Room Service Charges Phone Charges Other Charges If the check in occurs in November-March the rate is $89/night. April-August is $99/night and September-October is $109/night. $10/night should be added if more than 2 people are in the room. More than 4 people are not allowed in the room, and a traveler can only request 1 room. A 15% tax should be added to the room rate and 10% tax added to all room service and other charges. No tax will be added for phone charges.
The program should use a function to calculate the total charges for the visitor's stay and output it to a label. There should be buttons or menus to calculate the total, clear the form, and exit the application.At least one of the button should call a sub procedure which performs its function. I don't understand how to set this program up and I'm not sure what it means.
create an application that calculates the registration fees for a conference. The general conference registration fee is $895 per person. The is also an optional opening night dinner with a keynote address for $30 per person. additionally, the optional preconference workshops listed in table 7-16 are available. [code] When the user clicks the select conference options button, it should display the conference option form the conference options allows the user to select the regular conference registration, the optional opening night dinner, and an optional preconference workshop.(the user cannot register for the optional events, however, without selecting the conference registration of $895.) when the close button is clicked the conference form should be removed form the screen and the total should apper on the main form. [code]
The hotel has 8 floors and 30 rooms on each floor. Create an application that calculates the occupancy rate for each floor, and the overall occupancy rate for the hotel. The occupancy rate is the percentage of rooms occupied, and may be calculated by dividing the number of rooms occupied by the number of rooms.When the user clicks the "Complete Report" button, a loop should execute and iterate 8 times. Each time the loop iterates, it should display an input box for one of the hotel's floors. The input box should ask the user to enter the number of rooms occupied on that floor. As the user enters a value for each floor, the loop should calculate the occupancy rate for that floor, and display the information for that floor in the list box. When the number of occupied rooms has been entered for all the floors, the application should display the total number of rooms occupied and the overall occupnacy rate of the hotel.I have some of the code but I'm not sure which way to go now!
The program is a hotel occupancy form The Hotel has eight floors and 30 rooms oneach floor. I'm supposed to create aapplication that calculates the occupancy rate for the hotel. Theoccupancy rate is the percentage of rooms occupied, and may becalculated by dividing the number of rooms occupied by the number ofrooms. For example, if 18 rooms on the first floor are occupied, the occupancyrate is: 18/30 = .6 or 60%. The form has two out labels called totalrooms occupied and overall occupancy rate that holds two output text boxes todisplay the numbers its only three buttons Calculate report,close, and exit Its obvious what the exit buttons issupposed to do the clear button should clear all the controls on the floor
Now the complete report button is supposedto loop and iterate eight times. Each time the loop iterates, it should displaya input box for one of the hotel floor. The input box should ask the user asksthe user the user to enter the number of rooms occupied on each floor. As theuser enters a value for each floor, the loop should calculate the occupancyrate for that floor and display the information for that floor in a list box.When the number of occupied rooms has been entered for all floors theapplication should display total number of rooms occupied an overall occupancyrate for the hotel. (the hotel has a total of 240 rooms total)

VISUAL BASIC 2008. Program Description: Create a program that calculates the amount of quarters, dimes, nickels, and pennies are needed from an amount of change (entered in pennies). The program should use the largest coins possible (for example, fifty cents should use two quarters, not five dimes, fifty pennies, etc.)
I don't want the code already written out, I need somebody to walk me through making a code. Also, this is my first class dealing with computer programming so all we've learned so far is declaring variables and how to label objects, the simple stuff. I'm at a loss at how to start because a quarter is worth 25 but the program is supposed to show how many quarters once a user enters the amount in cents.
I have created an application that calculates and displays the quarterly payment on a loan but when i run the application the paymnet amount is showing with () around the amount I can't figure it out.
I'm creating an application that calculates render times for Maya. I kinda got bored of coding all the technical stuff so I started to mess around with the interface. I'm trying to create a combobox color picker.

I now have another problem. The message body is using the XMLMessageFormatter to store the body in MSMQ. I can read this out into an XDocument, but I cannot seem to get any nodes now. The root element is as that the XDocument gets is as follows:
I'm having trouble figuring how to code the calculations for a Pocket PC application that calculates the cost of a cell phone bill. From a Pocket PC the user should enter the number of minutes used during the past month, in order to calculate the cost of the cell phone bill. The plan allows 300 minutes for $29.95 per month. For each minute over 300 the cost is $0.17 cents per minute. Tax and Fees are $4.85 a month.
1. User enters the number of minutes used during the past month.
2. Based on plan rate of 300 minutes for $29.95 and 17 cents for each minute over 300 calculate the cost of the bill including the fixed cost of $4.85.
3. The user must be able to initiate the calculation and display the individual charges and the total cost of the cell phone bill.
4. The user should be able to clear the number of cell phone minutes, the individual charges and the bill total
If negative number is enterd for the cell phone minutes, the user should be advised and asked for a valid entry If non numeric value entered for the cell phone minutes, or if left blank the user should be advised and asked for a valid entry.Application is deployed on the Pocket PC emulator built in VS 2008
Enter # of Minutes ________ (user enters) Regular Minutes Charge ___ (29.95)
I am buidling an application that users can use to submit text data and attachments to email recipients. Certain fields, quite a few in fact from the textboxes in the app will be in the email body, and some in the subject line.This is how I am doing it right now, but I figured there has to be a better way. In VB it is one single line of code, not many like it is here. Ideally I would like to be able to better control the positioning in the message body.
While I understand there are properties of MailItem that would allow one to programmatically create a formatted email, I would prefer the ability to copy the body of an email that is already formatted to my liking (bolding, italicizing, embedded pictures/tables, set margins, etc.) copy and paste it to a newly composed email such that this formatting is preserved.
I want to create an index on my table. I used the following command Code:
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False") cn.Open() cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT (ITEM_NO)", cn) cmd.ExecuteNonQuery()
Now I want to use this. Is there a file created with some extension when i do an Indexing?. Is the above statment actually index the field, ITEM_NO or do i have to use ALTER TABLE command? Currently I am getting error "Cannot execute data definition statements on linked data sources"
I've looking everywhere but can not find out how to create index on vb 2008.what I mean is like in vb 6, for example in TextBox properties, I can create index. how is this working in vb 2008?
I have a question related with VB.Net Code. I see that the DataTable we can use: DataTable(0)'This return a DataRow with the selected index In the intellisense I see that this functionality can achieve with a extension... but, If I create a extension, always I need refer the Extension before to use it
The objects I am trying to mass select are text boxes, and I am trying to select them all, without tediously selecting all of them, to see if any are blank and place in a 0 if any are.
I have a listbox (ListBox5) and what i want to happen is when, and only when, a USB mass storage device is inserted a list of the files will appear on the listbox - and then when your press the button marked "Remove File" it will delete the selected file off the USB
I'm doing a mass email system using Microsoft Visual Studio 2005 and I'm suppose to use my codes to read the Email address from my Sql Server and send messages. My Default Smtp server is already running but my codes still cannot read the data from the sql server and send emails..
I'm making an art program involving 8x8 squares on a grid, but there are 64x64 grid square PictureBoxes for each grid square. Meaning there are 4096 picturebox squares to be setup.
I'm having them names like pic0001, pic0002, pic0003, etc... but re-naming them individually would take me forever. Is there a way to mass re-name them at once?
I had restart my program for 5 times, and i still can get through it. the due date just around the corner.
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."
