General Software Discussion / Re: Any suggestions for a good freeware DBF to Excel and Excel to DBF converter

« on: February 08, 2009, 08:03 AM »

Hello,

Excel itself can open DBF files.  Try Open and change the file types drop down to dBase files (.dbf).  That's the way it is in Excel 2007, i believe it is available in earlier versions of Excel as well.

HTH.

Developer's Corner / Re: Forms calls a class, class interacting with a form

Yes, you have to declare a special constructor (New) and have a private variable in the class:

Public Class MyClass
    private _tx as TextBox

    Public Sub New(ByVal txtBox as TextBox)
        _tx = txtBox
    End Sub

    Public Sub MyFunction(ByVal someText as String)
        _tx.Text = someText
    End Sub
End Class

Hello,

There is more than one way to do this; one is to have the runfunction method take a TextBox as a parameter:

Form1:
textbox.text = "";
Class class = new Class();
class.runfunction(textbox)

Class:
public void runfunction(TextBox tx)
{
 tx.text = "Some text"; // This would never work, but how could it?
}

Developer's Corner / Re: c# assignment: Problem with random

« on: March 20, 2008, 10:59 AM »

Hello,

You need to supply the Random constructor with a seed value.  See http://msdn2.microso...ibrary/ctssatww.aspx for examples.

I'm trying to pick two random numbers for assignment 5 of the c# school. I'm using the following code

Code: C# [Select]

1. private void fillFirstBoxes()
2.         {
3.             userCard1Text.Text = Convert.ToString(functions.GetRandomCard());
4.             dealerCard1Text.Text = Convert.ToString(functions.GetRandomCard());
5.         }
6.  
7. ...
8.  
9.     public class Functions
10.     {
11.         private int RandomNumber(int min, int max)
12.         {
13.             Random random = new Random();
14.             return random.Next(min, max);
15.         }
16.  
17.         public int GetRandomCard()
18.         {
19.             int[] cards = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10 };
20.             int random = RandomNumber(0, 12);
21.             return cards[random];
22.         }
23.     }

The trouble is that 90% of the time the two numbers are the same. Occasionally (about 10% of the time) the numbers are different but it is rare. So what am I doing wrong?

I know that computer random isn't really random, but surely it only takes a tick?

As a last resort, if normal uninstall does not work, you can try the tool mentioned here (it helped me when I had a similiar problem):

Take your time and be very careful!

N.A.N.Y. 2008 / Re: AccuTicket v1.0 - Free Ticketing Software

« on: December 29, 2007, 09:30 AM »

Hello,

This is from memory, but in .NET there is a GetExecutingAssembly() function that will return the full path of the excecutable that is running.  This could be used to set/get data files.

Hope this helps.

Hello,

Maybe NetStumbler is what you're looking for.  I don't have the link handy, but a search should come up with it.
