Unable To Complete In Roughly 15 Mins Give Or Take?
Jan 8, 2012
after reading a topic that Chris Rutland wrote about student in final year (link)[URL]...So i was able to complete this in roughly 15 Mins give or take. it also said multiples of three and five. Which i would have understood as 3 * 3, 5*5 as so on, but when I thought about it they would never match within 1 - 100 so I took I must have misunderstood so I then done it as 3 + 3 and 5 + 5 and so on. Which would then give matches for FizzBuzz. So my question is from my code below what would you do different. Could any of you write this with less lines and if so how.

I have a small problem with my AutoComplete Textbox in that it doesn't replace what I type with the item from the drop down list. This is hard to explain so I will start off with the AutoComplete of the combobox and how it works.
If I create a combobox with the following listitems (pay attention to case as this is the actual problem)
Item1
Item2
Production1
Production2
Now I can set my AutocompleteSource to ListItems and when I begin typing into a combobox I get a list of matches (Using SuggestAppend)So if I type i (lowercase) I get a list containing Item1 and Item2 with tem1 added and selected for overtyping in my combobox text. Now if I press Tab or Enter, My combobox.text is updated with Item1 with the proper casing from the list even though I typed a lowercase i. This is not how it is working in the textbox. Using the following code:
Dim mySource As New AutoCompleteStringCollection
mySource.AddRange({"Item1", "Item2", "Production1", "ProductionItem2"})
TextBox1.AutoCompleteCustomSource = mySource
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend
When I begin typing in the textbox, again, the list drops down. And again, when I type a lowercase i, I get a list containing Item1 and Item2 with tem1 filled in to my textbox. Now if I press enter or tab, my textbox is filled with item1 instead of Item1 as it did with the combobox.
My question is:Is there a way to ensure that the text in the textbox matches the actual case of the item in the customsource? I can click the item in the dropdown and it appears in the textbox just fine. But I don't want to force my users to have to do that.

I want to create a Timer such that I can reset the time to say 00:00:00 (hrs:mins:sec) and be able to stop, reset and start the timer as needed. I have actually created one from the scratch but it seems like it is long on code. Any ideas on how best to do this?Only performance counts!

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

23430 seconds = 06:30:30 (hh:mm:ss)52230 seconds = 14:30:30 (hh:mm:ss)The problem occurs when my total seconds goes over 24 hrs. So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result. I potentially need to be able to calculate upto 1000 hours - e.g 3601839 should equal 1000:30:30 (hh:mm:ss)
Dim ts
As TimeSpan = TimeSpan.FromSeconds(95430)
Dim hours

What I want is: To scan a website every 15 mins or so, (craigslist in this case), and email myself any new posts that come up. I know I need to use WebClient, but I never used that before. Another question would be how to only email when a new post is up and not receive the same email every 15 mins.

I have a datagridview which fetches data from a local SQL server. Now, I have a setting called My.Settings.database_url which indicates the hostname of the SQL server.
Now, the problem is that if the host name is incorrect, instead of getting an error, the app just freezes. So what must I change in order to fix that?[code]...

Is there a way to give a value to multiple variables (integers in this case), instead of all at once?
For instance, I have Dim aceVal, twoVal, threeVal, fourVal, fiveVal, sixVal, sevenVal, eightVal, nineVal, tenVal As Integer and, pending listbox selection, I'd like to assign threeVal fourVal and sixVal all values of -1.

I am a beginner who used to use VB5 seven years ago, but am now trying to get up to speed using Visual Basic .NET 2010 Express in XP.
A difference I have noted is that in VB5 my buttons appeared to be three dimensional (raised) due to shading, etc. With VB2010 my buttons are plain 2D. I have not been able to find a property to give them the 3D appearance.Is this a limitation of using VB Essentials? If not, what properties give buttons the appearance of 3D?
