Use The Internal System Speaker To Generate Sound?
Jun 12, 2011
I know it is possible to use the internal system speaker to generate sound.
EG
System.Console.Beep(500, 500)
'Beep(FREQUENCY,DURATION)
However i was wondering if anyone knows if it is possible and how to go about using said system speaker to speak - MESSAGE YOU ARE NOT AUTHORISED - for example
I am creating an app that allows admin access via a usb key (this is working fine) and i want their system to sound an alarm with a warning message should they try to force thier way into the admin section without the admin usb key.

I just started programming in vb 2008 Using vb studio 2008 and vb 4.0 Running Windows XP Home Edition My question concerns the capabilities of vb to call for the internal sound cards and/or midi synthesizer.Can a module call the sound card for it to play MULTIPLE notes at the same time, notes of fixed frequency and duration?
I have tried programming vb 4 AND vb2008 for them to modify the default BEEP sound: using a code i found on internet:private declare Function Beep lib "kernel32" (byval soundFrequency as int32, byval soundDuration as int32) as int32

I am building a permissions system in vb.net against the normal Windows Server file system. Have not decided on the best method, but is there a way to get access to some kind of internal GUID that Windows might store for a folder. If I just store the path for security, then it quickly becomes very hard to update a database storing path information to get security information. If a folder had some kind of internal GUID structure that would be great. Is this available?

I have been developing some components for our products at work, and one of them is based off the flow layout panel.What i would like to do is provide a custom designer for it, but without loosing the features provided by it's default designer (System.Windows.Forms.Design.FlowLayoutPanelDesigner) which is marked as internal.Using Reflector i thought i would just implement it again myself, seeing as it inherits from 'FlowPanelDesigner and that from PanelDesigner` all of which are internal.
Why would these classes be specifically marked as internal? Is it due to them being specifically for Visual Studio use, and thus not 'framework' code?Also, is there an easier option that re-implementing all the functionality?

Does anyone know how to get and set the system sound volume? I have tried every method I've found on the net and none of them work. I've tried the winmm.dll APIs with no luck. I've also tried waveOutGetVolume/waveOutSetVolume, which didn't work. I'm using Win 7, but need a solution that works on XP+.
Right now I use the VolumeUp keyboard event, but I need to be able to get the volume and set it to a specific level.

I am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).

I'm using the following code to generate a CSV file containing data from a dataset. The CSV generates fine and a prompt box displays so that the user can either open or save the csv file. What I'm wondering is whether it's possible to save the CSV file?
Edited with solution (NB I don't need the prompt box to open as I'll be writing additional code to generate and save a number of files and then display links to them). This saves the dataset as a CSV on our server.
Protected Sub exportBtn_click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ds1 As DataSet
ds1 = csvdownload.ReturnNewPledges()

I have asked questions about this before but my program has came to cross roads where I require more flexibility in my security procedures.At the moment I generate a specific key based on certain details about the system, and I hash this data to file, which ensures it will only run on this system.
However it has now got to the point where I have a need for providing keys which will carry settings for the program within the key. So that if a customer wants an update its the matter of sending an updated key, which will allow certain areas of the program to be unlocked/locked.Obviously I can no longer use the hash, as it can't be decrypted. I am looking to use key encryption system, which will allow to encrypt data within a license key. But obviously it brings the problem of where to store Crypt & decrypt key within the program.

I have a function that accepts a string and generates an email attachment based on that string. It works fine for html pages, text documents, and so forth but I can not get it to generate a PDF file.
Code:
Public Sub SendMail _
( _
ByVal strFrom As String _
[code]......
If I save the file attachment as Whatever.PDF i get the error that it was not encoded properly.I am using datadynamics active reports PDF exporter to generate the PDF
dim pdf as new datadynamics.activereports.export.pdf.pdfexport
sendmail("from@", "to@", "test", "test", pdf.tostring, "pdf.pdf")
I think the problem is I am converting the PDF to a string, and then trying to convert it back to a PDF and attach it to the email but I am not 100% sure.

I'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.
