How To Reset Decimal Array
May 4, 2009
I'm trying to get my exersize to work but am stuck on 2 fronts.
1. I don't seem to find a way to reset my resultArray. As it works now i get the result from the first test second test and so on each time.[code]
2. My print function doesn't read 'nothing'.I'm pretty sure that when i find a way to empty resultArray i'll fix this problem at the same time.But for now i'm hopelessly stuck.[code]

I have an array structure. and I'm done with it at some point. So I need to reset that array structure so I can start over! Is it possible to be done even with the sub array inside that structure array?

I have a class I am working on for a program I am writing while I am stuck at hospital 3x a week and was wondering. If my class has a Reset function that sets the count variable to 0, can I then say that the Data array is equal to "nothing" and wipe all the data that was in it?
Below is the class structure so far:
Private Count As Integer = 0
Private Data() As Integer
Public Sub Add(ByVal value As Integer)
Count = Count + 1
[Code] .....

I got on my form textboxes, checboxes but also a groupbox which holds texboxes.
The idea is to be able to clear and reset all of these by clicking a reset button.
At the moment i got this
Private Sub ClearFields()
Dim ctrl As Control
[Code].....
But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.

I want to sort a decimal array (currency with the places). I'm sure that I could find a bubble sort and modify it to suit my needs but it would seem that there would be a clean solution out there so I don't have to reinvient to wheel.

Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .

How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

If I have the code:Dim x as Decimal = 100.0m

Maybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:
Dim MyNumer as TwoDecimalNumber
MyNumer = 1.124
Msgbox(MyNumber) 'This would pop up a box showing "1.12"
[Code]....

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..

I've created an application that runs queries against a SQL server (via Data Adaptors) in VB.NET 08 and returns the results to a DataGridView. It works great and returns my data, but when I switch to a different query that returns different columns, the DataGridView keeps the old columns from the previous query and adds the new columns from the new query to the end (far right) of the DataGridView. Is there a way to counter this? I don't want those previous unused columns showing up in my results.I tried setting the DataGridView DataSource and DataMember to Nothing and that didn't fix it. [code]

I'm currently having an issue where an updatepanel does an async postback and loses the tab order when the partial postback occurs.When you run through the tabs the tab order works correctly, but then you press a button and the partial postback occures the tabindex is reset.
