I'm trying to play a MIDI file in my VB.NET (VB 2010 Express) and things work well with the code from this other question here on Stack Overflow, which I translated from C to VB.However, I also need to PAUSE, while that code is only for open and stop. I edited the code like this:
Imports System.Runtime.InteropServices
Imports System.IO

I am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.
View 1 RepliesI am looking for a way to play the usual MIDI sounds in a VB program. Similar to the beep program (ie console.beep, leading to timer1.start etc.)but instead of an annoying bleep, have a MIDI sound (like a flute, violin, clarinet, etc.). Is this possible in VB 2008?
View 10 RepliesI 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
[Code]...
I want to build a system that will take the input from an electric guitar and capture the frequency of the sound. and when the frequency is captured, the system identify the chord, and create new controls to represent the audio frequency. i want to use the label as the controls. so when the controls is created, how can i know that the user is click on what label. is there something like label1.click in vb 2005 express? then when the label is all created, i want the system to read all the labels integer as the sound of midi. so i have to assign what integer for what sound.
View 2 RepliesFor a school project I need to make a timer with a bell sound that sounds every 60 seconds in VB, I cannot work out how to make the bell sound on the 60th second, I am not getting any errors in the VB console, so I assume that I am just using the wrong code or it is in the wrong place.
Public Class OSCETimerControl
Dim t As Integer
Dim s As Integer
Dim a As Integer
[CODE]..........
There are actually 3 text boxes (not yet coded the final one) one for minutes, one for seconds and the final one is for the bell sound which will not be visible.
There is this software called Harping midi. You can view it here [URL] I would very much like to recreate this software but extend on it. For example. I would like to be able to pick up the "midi notes" and then translate that to guitar tabs. I would like it to have the same features (channel filters, tempo control) those sort of things. Where would I start???

I'm trying to add a new feature to some software I have developed but am having difficulty. Essentially I want to add a 'Pause' and a 'Resume' feature.I have a timer which counts down.

If togo.Ticks < 0 Then
Timer.Enabled = False

When the Start command button is clicked the timer starts counting down from what amount the user inputed. I've added an elseif to pause the timer and this works ok. When I click resume the although the timer text has paused the actual timer has not and continues from where the timer would be if it had not been stopped. Much like a stopwatch lap timer. Could you help me with my Else statement.
If StartButton.Text = "Start" Then
StartTime.Text = Format(DateTime.Now, "HH:mm:ss") 'Hour(Now) & ":" & Minute(Now) & ":" & Second(Now)
txtTimeLimit.Text = HourUp.Text & ":" & MinuteUp.Text & ":" & "0"
mTestEnd = Now.Add(TimeSpan.Parse(txtTimeLimit.Text))

I am trying to find a way to resume a thread after catching the AbortThreadException and calling AbortReset.
My thread is running a loop to control two motors used in a raster scan. Once the button is pressed to begin the scan, I want to be able to click a stop scan button and have the following happen:
1. AbortThreadException is thrown and caught- a window comes up asking if you really want to abort the scan. Click yes for abort, no for suspend, or cancel to continue scanning.
2. Given users answer the program responds accordingly- If cancel, then the scan should continue right where it left off and not restart.
My problem occurs in my understanding of the thread events. I am not sure how to tell a thread to wait for a button event nor do i know how to tell a thread to continue where it left off. I also noticed that the 'suspend' and 'resume' methods have been deemed obsolete and i am not sure of the alternative way of doing those actions.
The following is the code used to catch the exception and execute the task.

I want to make my form freeze for 5 seconds before it resumes to the next form.So I have a form that says : Establishing a connection....
But I don't want it to make a connection, i just want the user to think that it's making a connection.
And I then want it, when the timer reaches zero, that it would resume to the next form.
I just need the code of the timer behavior.
I am thining of using a boolean value per each backgroundworker to flag their completion and check all of the boolean values but there should be a better way,

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.

Is there a way to generate a pure tone (e.g. 440 Hz) for a specified period of time through the sound card without using having to find or make a separate .wav file for each tone.I tried using the "Beep" function, but while it produces the tone for a specified period, it sounds broken up into a (probably 500ms) time frame which repeats with an audible space between the repetitions.

View 1 RepliesIs it possible to convert MIDI files (.midi or .mid) into a .wav or .wma file in Visual Basic.NET (2010)? If so:
1: How would this be done?
2: If the output format can be .wma, how can one write the tags (such as artist, album, etc.) to the file in VB.NET?
I am saying .wav or .wma because I know that Microsoft does not have any rights to the MP3 file or something like that.
I wish to get my VB 2010 program to wait a few seconds after executing a command, and then exit.
