I have a space ship, and am wanting to calculate how long it takes to turn 180 degrees. This is my current code to turn the ship: .msngFacingDegrees = .msngFacingDegrees + .ROTATION_RATE * TV.TimeElapsedMy current .ROTATION_RATE is 0.15, but it will change.I have tried:Math.Ceiling(.ROTATION_RATE * TV.TimeElapsed / 180)

Right now I can add background music in my program by using this code
My.Computer.Audio.Play(My.Resources.Music_3, AudioPlayMode.Background)
I can also turn it off and change the music by using this code
My.Computer.Audio.Stop()
My.Computer.Audio.Play(My.Resources.Another_Music, AudioPlayMode.BackgroundLoop)
Is it possible to pause the music then if I resume the music it will just continue the flow? I mean if I pause the background music in 33 seconds and the music has 50 seconds and I resume it will just continue playing in 33,34,35 etc.. seconds?
I was wondering if their was a way to for me to turn off events and then turn them back on in my program or just queue them up until i am ready for them to be excuted. Kinda like how a OS turns on and off interupts. Is this one of those general programming no-nos?

View 9 RepliesFirst 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:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox4.Text = TextBox1.Text + (TextBox2.Text * 1 / 60) + (TextBox3.Text * 1 / 60 * 1 / 60)
End Sub
End Class
Textbox1 - Degrees
Textbox2 - Minutes
Textbox3 - Seconds
Textbox4 - DECIMAL RESULT

View 1 RepliesI know that LINQ queries are deferred and only executed when the query is enumerated, but I'm having trouble figuring out exactly when that happens.Certainly in a For Each loop, the query would be enumerated.What's the rule of thumb to follow? I don't want to accidentally enumerate over my query twice if it's a huge result.
For example, does System.Linq.Enumerable.First enumerate over the whole query? I ask for performance reasons. I want to pass a LINQ result set to an ASP.NET MVC view, and I also want to pass the First element separately. Enumerating over the results twice would be painful.It would be great to turn on some kind of flag that alerts me each time a LINQ query is enumerated. That way I could catch scenarios when I accidentally enumerate twice.
I dont even know if you can do this in vb.net but, how do you change the pictureboxes x2 y2 to tilt some degrees other than 90 degree angles?
View 2 RepliesI'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)

View 4 RepliesCreate 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

After converting all degrees-->decimal, and decimal-->hours, how can i use Tan, Cos and Sin formula in vb.net? I want the user must enter an input (which it is a coordinat-->i already convert the degrees-->decimal value as suggested by stanav and paul.
The questions like this (i only calculate on paper but dont know how to implement in code):
Input user need to enter:
-latitude local (e.g. 1.4875)
-longitude local (e.g. 103.3883333)

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
