US To Metric Conversions?
Feb 9, 2009
Write a program to convert a U.S. Customary System length in miles, yards, feet and inches to a. Metric System length in kilometers, meters, and centimeters.
I found this same project on these boards already however I received an error and was seeing if someone could see what I did wrong.
My error message is: 'lstResult' is not declared
Public Class lengthConversion
Private Sub convertBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles convertBtn.Click

Declare constants for all numeric values in the two formula above. The variable used to represent the number of meters and the numeric constant 39.37 must be declared as the data type double. the constants and data types in the first formula should be declared as integers. Convert the Total Inches in the second formula to a Double data type before using it in the calculation. Set Option Strict to on in your code. (Hint: After the number of meters has been determined, the maximum number of kilometers can be computed from Kilometers = Meters/1,000. Next, the remaining meters can be determined from: Remaining Meters = Meters - 1,000 * Kilometers. The number fo integer meters in Remaining Meters then can be determined from: Integer Meters = Convert.ToInt32(Remaining Meters). Continue with the same technique to compute the number of centimeters.)

how to convert a metric unit to standard. I will be converting Feet/Inches to Meters/Centimeters and vise versa as well as pounds/ounces to kilograms/grams and vise versa. I can input the values into my Textbox to where it reads " x'y" ," however, when I go to code the Convert button (the same button has to be used for all conversions) how to separate out the text and then perform the conversion.

I'm looking for a fast way of searching a textbox containing plain text mixed with coordinate values.These coordinate values may contain no decimals or 4 decimal places after the decimal.I'm somewhat familiar with regex, but my uncertainty is the actual number of characters in each word will be different.[code]

im trying to create a program that will convert between metric and standard units.I chose length as my measurement so i have nanometer,millimeter,centimeter,meter,hectometer,kilometer,inc,feet,yard and mile.i wanted the input to be
- number to be converted(text box)
-unit number is in(combo box)
-unit to convert to(combo box)
i know how to do combo boxes,buttons and labels and stuff.The output is the converted number this is what i have so far but its soooo wrong?
Public Class Form1
Private Sub Convert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Convert.Click
Dim Inch, Feet, Yard, Mile As Integer
Dim Nanometer, Millimeter, Centimeter, Meter, Hectometer, Kilometer As Double

I am having a bit of an issue and would like some opinions. I have a settings class that I use in my program that gets passed around to various pieces of the program. When the program exits, the settings class is serialized out to an xml file. When the program starts the settings class is serialized back from the xml file.If the program doesn't find an existing xml file, the defaults in the class are used and a new xml file is created when the program exits.This all works well. Here is a trimmed down version of my settings class:
Public NotInheritable Class UserSettings
Private _Length As Double = 10 'feet
Private _Name As String = "Inert Material"
[code]....
The problem that I am having is that if the program units are metric, then the default values are always converted in the constructor and the xml serializer then stuffs the values that exist in the configuration (over writing the converted default value which is what I want) into the proper properties. The reason for this behavior is to make sure that that new properties that don't exist in the xml file have a proper default value when metric units are required.
It seems wasteful to convert all of the default values every time when working with metric units? Is there a better way to do this? My full class has currently about 15 default values that need to be converted to metric equivalents. Ideally I would only like to convert values that haven't come from the xml file.

I am making a program that calculates various results with variables entered by the user. What I am trying to do is incorporate a function that will allow the user to switch from metric to imperial easily but only when the ok button is pressed. Now I got all the coding done for the metric and everything is working fine. My problem is when I use the radiobuttons to switch the entered variable in the text box to the desired unit it gives me a 0 or a random number in the textbox...
I also have labels indicating each variables unit which I easily managed to change with the text box using this code. :
'Change Labels to Metric
lblMDegreeC.Text = "Degree C"
lblMDegreeC2.Text = "Degree C"
lblMmm.Text = "mm"
lblMmm1.Text = "mm"
lblMmm2.Text = "mm"
lblMm.Text = "m"
lblMm2.Text = "m"
lblMm3.Text = "m"
lblMDegreeC3.Text = "Degree C"
I created all the coding to convert the metric variables to imperial. My problem is changing the textbox text when the user switches the units during run time. The labels change without a problem but the textbox never works. I have attached the coding for the file.

I usually use the developer fusion online code converter to convert code snippets from C# to VB.NET.It partially fails especially in LINQ or complex interface / inheritance scenarios. What are your experiences with other converters? Can you recommend another tool or website?

I am rather new to OOP and I have, what may be, a simple question. I am developing an architecture for a project that includes some object inheritence trees. I have been running into a bunch of narrowing conversion issues (the old 'Unable to cast object of type x to x' error). I understand the limitations of narrowing conversions and why this error exists, but I'm not quite sure how to get around it architecturally. Here is an analogous problem to mine...

Is there a way to define an implicit conversion operator in VB.NET?
I can't remember ever seeing or hearing of anyone do this; but now I'm in a situation where I think it would be incredibly useful to define my own custom 'type conversion' for my class.
As an example - let's say I have my own class, 'AwesomeDataManager'. It does not inherit from DataTable, but it holds data in a similar fashion to a DataTable. I would to be able to say, 'myDataTable = CType(MyAwesomeDataManager, DataTable)' and have it execute some code inside my class that would return a populated DataTable.
Granted, I could do something like 'MyAwesomeDataManager.GetDataTable' but for the sake of integrating with an existing code base, I'd like to avoid it.

Have been obsessed with DataTypes recently and would like some thoughts, etc. on the following: What's going on is when the BindingSource.PositionChanged Event fires, I capture an Integer relating to another tables Primary Key and then filter that DataTable to select the matching record.
So the focus of the question lies in the first 3 lines in the event. First example creates 2 objects, 2 lines of code. Second example does it all with one line... not sure if it creates only one object or not, seemingly not.. can't tell for sure. Which is "better"? Am I really approaching this from the right angle? Beside y'all here on this forum and Google, I'm self-taught and looking for some validation.

I am struggling to get this to output calculations correctly. Have I properly made my conversions between decimal,string and so forth. Is that the only reason that a calculation would not produce the right result or is there another reason? I have negative total results for output when they should be positive.
Dim decAmount As Decimal
Dim decInterestRate As Decimal
Dim mdecFutureValue As Decimal

i am using integer for days and miles, and the calculation is for money so i am using decimal in one function i am allowed to CDec the days for the calculation and the next function it gives me an error.
I dont see where what i am doing is any different than the other.
Function CalcLodging(ByVal intDays As Integer, ByVal decRoom As Decimal) As Decimal
Return (CDec(intDays)) * decRoom ' This function allows the conversion from integer
End Function

How do I correct the error Option Strict On disallows implicit conversions from 'Double' to 'Integer'. ?
The two lines below that divide by 2 are causing the error.
Private Function StringToByteArray(ByVal hex As String) As Byte()
Dim NumberChars As Int16 = CShort(hex.Length)
Dim bytes As Byte()
Dim i As Integer = 0
bytes = New Byte(NumberChars / 2) {}

I get the error for both highlighted red parts = Option Strict On disallows implicit conversions from 'Integer' to 'Short'.
Also
I get = Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.

When I have Option Strict ON in my project, the IDE tells me that "Option Strict On disallows implicit conversions from 'System.Data.ParameterDirection' to 'String'." How can this be, since I'm using their built-in enumeration for the SqlParameter direction.
