VS 2008 Console.Beep Speed Adjustment?
May 8, 2009
i'm creating an alarm clock for my computer. my alarm is the console.beep() sound. can I somehow alter the interval speed between the beeps using a trackbar? here is my code so far. all i want to know is how i would go about doing this, i like to learn the specific code on my own.
vb
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
lblTime = lblTime

How can I play a tone or beep using VB.NET. I don't want to use Console.Beep() because I want the tone to always come out of the speakers, not the speaker on the motherboard.Goldfish64

I have Visual Basic 2010, can you tell me how I could simplify this code without using the last IF statement? In other words, have console.beep when form2 comes up, but with out adding the extra line?What would an easier way to write this be? I mean instead of writing the separate if statement for the console.beep?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "valentines" And TextBox2.Text = "day" Then Form2.Show() Else MsgBox("That's Not It Theresa!")
If Form2.Focus = True Then Console.Beep()
End Sub

I'll try to clarify by using the following example. In here I have two Drop down lists (ddlInsertEmployee + ddlInsertCustomer) which should both be bound to fetch data from tables [Employee.EmployeeID] and [Customer.CustomerID] and insert it into table [Task].
The problem is that it inserts data from Employee.Fullname and Customer.Fullname into resp.Employee.EmployeeID and Customer. CustomerID.If I would change the Drop down lists to textboxes, and manually insert the IDs, it works like a charm, but this is not very efficient, I want to be able to see the entire Fullname.how to change my Sqlstring in order to make this work correctly.

I am using API calls to transform a Bitmap object. I have various physical transformations (rotation, flipping, scaling, displacement) as well as some colour adjustments (inversion, brightness and contrast)Everything works fine except for when I use the rotation or shear transformations in combination with the colour adjustment. In that case the colours revert to the original image.The interesting thing about this problem is that it seems to be dependent on the off-diagonal factors (eM12 and eM21 below) in the XForm matrix. For example, here is the rotation matrix:
Public Sub RotateClockwise(Radians As Single)
With XFormMatrix
.eM11 = Cos(Radians)[code]....
is there some way I can use both SetWorldTransform and SetColorAdjustment when using non-zero values for the off-diagonal factors in my XForm transformation?

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.

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 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?

I have a method in place to capture the "Enter" button when pressed and then move to the next control in the tab order. I do this to mimic Access (my users are spoiled).The problem arises when the current control is TextBox. I changed all my TextBoxes to multi-line and it got rid of the beep. However, it also added a "carriage return" and entered it as such in the DataBase.

For some reason, .NET applications that I've written seem to have issues if they're launched when Windows starts (by being in the Startup folder for instance). An application that can finish in 3/10 of a second if one launches it normally may seriously take 45-90 seconds to finish if it was launched when Windows loads. Even if I just manually wait 30 seconds after login and launch the program, it'll complete virtually instantly while a copy launched at startup is still struggling along, so it isn't just that Windows is still loading...this continues AFTER that finishes and all HDD activity stops.Writing something to disk using an IO.anything goes at about 20KB/s during this event.
