I've figured out the Variable declaration and coding to make it work:
Dim Celsius, Fahrenheit As Double
Try
Celsius = CDbl(txtCelsius.Text)
[Code]....
I'm gettting an "error": Option strict on dissallows implicit conversions from string to double? I have a textbox for celsius input that I want stored and converted into a label with the Convert Button Click Event.
I am creating a program that will convert Celsius to Fahrenheit and visa versa. The program must use a function to return the answer. I'm using a string function that will return either the temperature in Celsius or Fahrenheit or "Please enter a valid temperature" if anything but a number is entered. TryParse is used to check if the input is valid.
When using the TryParse method in the function I am trying to use a parameter to pass the variable that will store the converted data type value [Code] The line " If Double.TryParse(tempTextBox.Text, scale) Then " is supposed to check if the conversion is possible and if it is pass either F or C as a variable to the scale parameter. It seems to verify the conversion all right but it doesn't actually do the conversion. Why isn't doing the conversion? Both F and C remain 0. I can get it to work by using two more TryParse methods (one in each branch of the If else statement in the function), but I'd rather not do this.
This is what i have i need for it to run and ask for celsius instead of fahrenheit but it is not doing it..
[code]...
I am not understand this at all i am suppose also ask users to input a celsius degree for this part.its telling me i nedd to change formula to calculate the fahrenheit temp for this part.
I am not quite understanding I am working with Microsoft Visual basic .Net programming and I Have this so far
Sub Main()
Dim fahrenheit, celsius As Double
Console.WriteLine("Enter a value for fahrenheit tempature:")
[code].....
I've been looking at this code for about 3 days now and I can't seem to get what I did wrong. When I run it as a console application I get "0 : 32" a lot of times.
The purpose of this code is to start at 0 degrees Celsius and work our way up to 100 by 10's. IE:
0 degrees C = 32 degrees F
10 degrees C = 50 degrees F
etc.. too
100 degrees C = 212 degrees F
Module Module1

I've got this far with my interface and layout and buttons. I cannot figure out to do the functions for converting to and from celsius and fahrenheit.[code]...
View 2 RepliesI have already completed most of the program and it works, except when there is no input in the Fahrenhiet or is left blank.I get the following exception: on this code: Inputsingle = CSng(TextBox1.Text).Conversion from string "" to type 'Single' is not valid.Here is my code:
'Project" Convert Tempertures
'Progammer: Cathy R. Hjelm
'Description: Convert Fahrenheit temperture to Centigrade Temperature using a convert button and output Text Box[code]....
The formula is F = 9/5C + 32 where F is Fahrenheit and C is centigrade temperature.I've this code but the result shows 32 no matter what I enter. How come?
Dim intTemp As Integer
Dim intResult As Integer
' calculation
intResult = (1.8 * intTemp) + 32
[code]....
The lesson exercise is to convert from both Cecilius and Fahrenheit using two sub procedures. I thought I had this one in the bag..seemed pretty easy when I was doing it but my calculations are always 0..
This includes two radio buttons one for F and one for C the tempature text box and the results lbl along with two buttons, convert and exit. (see attached screen clipping)
Option Explicit On
Option Strict On
Option Infer Off

I'm new to visual basic and have decided to make a temperature conversion program. I've attached a screenshot to aid in my description. The program reads the temperatures on the left(from text boxes), converts them, and displays the answers on the right in text boxes. The program has a fever check at the bottom which displays whether or not the converted values are a fever.
I've managed to get this to work no problem, but I'm trying to get it so if the user enters the temperatures directly into the "result" textboxes, that the fever check still works. Unfortunately I'm having no luck, the fever check will only display a message if the values have been converted, not directly entered by the user. Here is the code I tried(fever.Text is what is displayed in a textbox above the fever check button):
Private Sub FeverCheck_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FeverCheck.Click
'Turn string values entered into Decimal Values so they can be compared to decimal values
Dim fahrfever As Decimal
Dim Celsfever As Decimal
'The following two lines have problems when debugging

I am working on a school project to make a temperature converter that when fahrenheit is entered into textbox1 and then tabbed, the conversion to celsius, rankine, and kelvin is displayed in textbox 2,3, and 4.My instructor showed me how to input the code for this, but it isn't working correctly. I know I need more code to get this right but I am a newbie to programming and my instructor doesn't insruct very well. Can someone please tell me what I need to do to finish this coding? This is what I have so far:

View 7 RepliesI had web application (website?) that was started in VS 08 (this was the VS 08 that comes with SQL Server 2008 - not the full-blown version) and I loaded it in to VS 2010 (this is a recent Professional version upgrade from VS 05 Pro). The web app is a HealthVault application created by the HealthVault Application Manager that ships with the HealthVault SDK.
