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 am trying to calculate the number of years for my calculate age event handler, however i am apparently missing a method or whatnot because im trying to calculate the age , can anyone suggest help on this. I need to subtract years to get my age but when i try the birthdate.Subtract (currentDate) method i get an error about not able to convert from LONG?
So below is what I have.

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 11 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

Using the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.
' Xc = 1965
' Xp = 0
' Yc = 5244

View 4 RepliesI certainly hope I don't aggravate you with what is certainly a very simple code problem. I have never programmed before, but I do have a background in tech support, etc. I have an assignment to do and it's frustrating to wade through the information out there to find exactly what I need and nothing more.The assignment has 3 parts, one of which i've done. We are to do the same function in both javascript and VB. I was able to take a sample we did in class that caluclates a 10% discount and modify it so it calculates the total. Now, I have to modify that into a VB sln file. then write about the differences but that part will be cake.
I am working in Visual Studio 2008 - that program is new to me as well. When I created my login and it asked what VB I'm using, I did not know but under theu of VS, it says VB 2008.hat I attempted to do was to take the instructor's sample discount code and modify it for the new purpose, but an error was generated. This is the sample code I started with:

So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.
