How To Get Decimal As Degrees / Minutes And Seconds

First of all I got app to convert Degrees, Minutes and Seconds to decimal. But now I need to get Decimal back to Degrees, Minutes and Seconds and I can't get it how to make it because I'm terrible with math formulas... Here is what I done so far:

TextBox4.Text = TextBox1.Text + (TextBox2.Text * 1 / 60) + (TextBox3.Text * 1 / 60 * 1 / 60)
End Sub
End Class

Textbox1 - Degrees
Textbox2 - Minutes
Textbox3 - Seconds

Winforms - TabControl Alignment - Rotate 90 Degrees To The Left

Dec 18, 2009

I'm having a weird behaviour with a left-aligned TabControl in VB.NET. Screenshot:

What I wanted was to have the tabs literally the same way they would be if rotated 90 degrees to the left. Does it have something to do with the fact I'm not (god forbid) using the standard XP theme? Any solution to just make it work? (Even if it's hard, but I don't want a control that has a contrasting style, I want the program looking consistent)

VS 2010 - Convert Latitude / Longitude Into Values In Decimal Degrees

May 30, 2011

Create a function named DecimalDegrees to refactor the code that converts a latitude or longitude into a value in decimal degrees. (This function will be used inside the functions ValueOf and Distance.)
Task 2a: Write the code for the function DecimalDegrees with an input parameter for DegreeString as type string, and returns the value as type Double.

Here is my code for the function part
Private Function DecimalDegrees(ByVal DegreeString As String, ByVal degrees As Double, ByVal minutes As Double,
ByVal seconds As Double, ByVal ID As Integer) As Double

I am having difficulties with the 2nd part which is I believe to take the code for the calc1 and calc2 buttons and somehow get it to convert to decimal degrees by the function I have created. The buttons would then be removed as the code would automatically take the latitude and longitude and convert the degrees, minutes and seconds into a decimal.

Here is the code for the current buttons:
Dim StartPtr, StopPtr As Integer
'To Replace Calculator 1 Button
'Convert degrees before passing argument - Latitude
StartPtr = 0

Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field

May 18, 2012

Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer

[CODE]...

The variables in the brackets [example] do not actually have brackets in them in the original code.  These are where the issues are.  For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')."  Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.  

-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop.  Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.

VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?

Jan 10, 2011

Say that i have the following code that parse about 20k records from the DB.

Code #1

vb.net While reader.Read()
  list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While

And then another code which does the very same thing but it seems to be a little cleaner.

Code #2

vb.net While reader.Read()
  Dim storeowner As Integer = 0
  Integer.TryParse(reader(0).ToString, storeowner)
  list.Add(storeowner)
End While

This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared

Aug 24, 2009

I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

Object Variable Or With Block Variable Not Set - From Property Get With Bindingsource.current?

May 31, 2012

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.

[Code]...

The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.
