VS 2008 Key Repetition Speed
Nov 20, 2009
Say you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.

The goal is simple... generate a set of random numbers with a certain range (e.g., 1-6, 5-10) with no repeats. I tried using a system with arrays where everytime a number has been generated, its marked as "used" and then the program is required to generate a new number. But it doesn't work!
Public randomnumgen As New System.Random
Public randomnum As Integer
Public iCounter As Integer
Public GotIt(7) As Boolean

How can I write all possible combinations to the console? For example, if user enters abc, then it will write aaa, aab, aac, abb, abc, acc, bbb, bbc, ccc.
Here's some code:

I have written an if...else statement which uses an array myArr and a string myStr as follows:
If myArr.Length > 0 AndAlso myArr(0) = "-1" Then
'Do stuff 1
ElseIf myStr= "xyz" Then
'Do stuff 2
ElseIf myArr.Length > 0 Then
[Code]...
It works exactly as I need. But It looks really confusing, mostly because the array length is checked twice. There must be a clearer way to write it, but I can't think of one. the order that each statement is executed is crucial. i.e. Stuff 1 has priority over stuff 2, which has priority over stuff 3.

I have a button that when you click executes a certain code, lets say I make a menu that when clicked on should execute the same code, so how can I do this without having to copy/paste the same code twice.

In the database there are two records with the same value and so, of course, in my list box the value is given twice.How do i remove this repetition from the list box? (still keeping it the same in the database)

I need to stop the execution of a program in VB.net. Within a repeating structure the program checks whether a variable is true or false. When the variable is false I need to stop the program execution. I do not want to close the program but simply stop it. One way I found was raising an exception, but I would not want to display the error message to the user. What is the best way to do it ?
Do
If myvariable=false then
throw new exception... 'Silent exception
end if
Loop until ....

My application works fine.However, I am connecting to 5 DBF files and the queries are very slow.[If I copy the DBF files to the local hard drive everything runs fast enough. 30-40 seconds vs. 1-1.5 minutes]The DBF needs to stay on the network.I am hoping that using the index will speed things up enough.Can anyone tell me how or give me a code example on how to index on DBF files?

I'm getting a bit more fluent in VB.Net, but am still a bit green around the edges in certain aspects. I'm creating custom controls, and am starting to rely heavily on AddHandlers to manage them.Until recently, I didn't realize that you can add multiple event handlers for the same control and same address
[code]...
The above code would create 10,000 copies of the same event, and if I would click on combobutton1, the event would fire 10,000 times. I only need to fire the event once, but sometimes my code is a bit circular, and there may be an instance where two or more addhandlers are designated for a given control and address. Is there a way to have a loop on my custom dispose event where it would look something like:
[code]...
Or better yet, remove all events from a control(On a side note, is there any way in the debug mode to see all the active events attached to a control?)

i am trying to complete a project. My task is to read large TXT files (300 files, 2.2 GB in total) read the customers inside, perform some data calculation and write each customer data to a separate txt file.
I made a code in VB6, it runs fine, however it takes 8 days to run on a quadcore processor, utilizing 20-30% of the CPU. Now I upgraded the code and am running on VB.NET 2008, the latest version. The speed still remains the same, and the CPU usage is also about the same.
Anyway I can make this process faster. I have a quadcore PC with 8GB of ram, possible to maybe make VB utilize all the CPU say 100%? so it executes atleast 2 to 3 times faster.

I'm working on a CMS web app (aren't we all) and wondering if it's better to store the content of web pages as files on disk rather than text fields in MS MSQL.
There will be thousands of pages, a lot of content, so I was loathe to burden the database when it might be quicker this way.
Does anyone know if retrieving the contents of a file on disk is overall faster than reading it from a large database field?
