InputBox Function - Program - Allow User To Input 5 Payrolls For Store 1, Store 2, And Store 3
Mar 22, 2012I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

EventHandler AddressOf Invoke?
Apr 22, 2011I wish to check the hard drive space used in a folder on a hard drive. This will happen continuously as a service, so it will be calculating the space used for thousands of folders all the time. I know that this code can be done easily in dotnet, but it seems to take a really long time. Are there any APIs to do this more efficiently, or does the entire looping process have to occur to do this check?

C# - Fix AddressOf Requires Relaxed Conversation To Delegate Error
May 23, 2011This is a mix of C# and VB.Net. I have a C# class with with 2 delegates:
public delegate string GetSettingDelegate(string key);
public event GetSettingDelegate GetSettingEvent;
public delegate void SetSettingDelegate(string key, string value);
public event SetSettingDelegate SetSettingEvent;
In a VB class I add handlers to the event:
AddHandler _gisCtrl.SetSettingEvent, AddressOf SetSetting
AddHandler _gisCtrl.GetSettingEvent, AddressOf GetSetting
When I try and remove the handlers:
RemoveHandler _gisCtrl.SetSettingEvent, AddressOf SetSetting
RemoveHandler _gisCtrl.GetSettingEvent, AddressOf GetSetting
SetSetting is OK but GetSetting throws a warning:
The AddressOf expression has no effect in this context because the method arguments to AddressOf requires a relaxed conversation to the delagate type of the event.
Here are the methods

How to fix this and why it is thrown in the first place? The 2 delegates/events/methods look similar enough that I don't know why one is OK and one throws a warning.
