Been doing VB2010 for about a year now, have recently started to push the boundary's for what kind of media I can incorporate into my forms. I haven't been able to play .wav or .mp3 files though. I have tried to follow tutorials on microsoft and other coding websites without success.

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
View 2 Repliesi've got a simple timer setup to start vlc
System.Diagnostics.Process.Start("c:\program files\videolan\vlc\vlc.exe")
only thing is, i'm not sure how to get vlc to automatically start playing when it opens up.
In my Windows Form's application, I enable and start a Windows Form's Timer for a state machine which interacts with various User Controls. In one part of the state machine where an external device is being rebooted, I need to disable the User Interface (a User Control's UI) for the time it takes the device to reboot. The problem exists in that once I use System.Threading.Sleep, the timer that fires the State Machine stops and never restarts. I even re-enabled the Timer and re-started it after the Sleep command but to no avail. Is this expected operation or should a Windows Form's Timer be able to restart after a Sleep?
Snippet of code from a step in the state machine below:
Cursor.Current = Cursors.WaitCursor
MainForm.Enabled = False
System.Threading.Thread.Sleep(8000)
MainForm.Enabled = True
Cursor.Current = Cursors.Default
MainForm.t1.Enabled = True
MainForm.t1.Start()
How can you access the Start Menu from a VB form for both Windows XP & 2000?
I've done a lot of research and haven't found anything that works for this.
I want to start a Windows Forms Project (VB.NET) using a simple text editor like notepad. I'm not interested in creating a button and other controls from scratch, I just want to know how to create a form, initializing controls without using the wizard.how to use command-line to compile the whole project?
View 2 RepliesBased on a thread earlier today, and in particular an answer that Cor gave wherein he
pointed to this article, I thought that I'd do some investigation. Many times here the question has come up about playing .mp3 audio files and NOT using the Windows Media Player object. In the article referenced above, he shows how this can be done via DirectX.
I've looked at DirectX before and it seemed ambiguous so I never really dug into it but it turns out to be pretty simple actually! I thought that I'd write this as a step-by-step of what I did so that maybe some of you will find use from it. The whole thing stems around using DirectX and to begin with, you'll need to download and install the SDK for it. If you haven't already,
try this link. Do be aware that it's a large download (about a half gig)! Once that's installed, create a form and add a reference to the class that we need for this. You can do this several ways, but the way I usually do is to right-click on the name in the Solution Explorer, then choose "Add Reference":

I want to play MP3 Files directly from the internet. I don't want to use other applications, like WMP, just my application.
I have a file that contains the list of the playable files: listoftracks.ini that contains:
hxxp://....../example.mp3
hxxp://....../example2.mp3
I wrote hXXp instead of http to disable links - in the files, they are http

This is tied in with the other discussion that I started last week about playing audio files using the DirectX classes. If you haven't yet had a look at that other thread,Using the same reference as in the audio application, let's set up a form for video this time. I started with a form that I then placed a split container on and in the lower panel of the split contatiner, I placed the buttons and other controls. Following is how I have mine set up:
Reread the thread on the audio player because the methods are very similar - in fact some are identical! However, this is video and it got a bit more involved as you might expect.The full code is here and I hope you'll find it useful to you. Following is a screenshot of the end result.

Is it possible to play 8 different and individual mono wave files to a 7.1 (8 channels) audio system using vb.net? (I undestand that the .1 speaker is the subwoofer and I'm not yet sure it can be replaced with an ordinary speaker.) The playing should start simultaneously and the files can be of different size/length.Is this something that should be done using win API functions if it can be accomplished at all.I just re-installed my old VB6 which I need to ugrade and vb.net would be the easiest for me so I placed this Q here.
View 2 RepliesI am working on an application in VB.net (.NET 2.0) where I need to open a dynamic amount of different audio streams. Normally, for audio files, one would suggest importing the Windows Media Player COM reference and adding a GUI-based element from the toolbox, but since I'll be working with a dynamic amount of these a GUI would be a terrible idea (especially with Tab stops).

View 18 RepliesWe have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?

View 2 RepliesI'm trying to make a "Simon" game with four buttons labeled 1-4. The game is supposed to read the numbers out loud, but i have a problem with that. I have 4 wav files from google text-to-speech, each named 1-4. I made an number generator that can return like this "42331", and the game is supposed to play 4.wav, 2.wav, 3.wav, 3.wav and 1.wav.
Here's what I got so far.
Public Class Form1
Dim rnd As New Random
Dim i = 0
Dim level As Integer = 5
Dim nums As String
[code] .....
It only plays 1.wav (the last in the sequence).
I have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:
Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub
The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.
The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?
I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.

Now, I have confirmed the files it is attempting to play are in fact valid video files. It refuses to play all but the last one.
I'm looking to see if anyone has a good reference for a third-party add-in that will allow me to play .mp4 video files inside my program without a need to embed a web browser in my program.

I'm developing a VB.NET Windows service which is costantly checking a BMS database for new alarms and making phone calls to warn operators remotely. I'm currently using a .NET TAPI wrapper and the SAPI 5.3 interop assembly, and the steps I'm taking to speak over the phone are:
Initialize TAPI interface;Make the call to the operator's number;Take the voice modem waveOut device id Set the voice output to that device id; Let SAPI do the magic. This is all working fine if I compile the code as a Windows console or forms application, but as soon as I compile and run it as a Windows Service, step 5 never occurs - voice modem calls but stays silent; everything else works, even digit monitoring.Now I know windows services are not supposed to interact with the desktop, so things like UI elements and playing sounds are a no-no, but I'm struggling to find an alternative which doesn't involve using the wave API and can be developed in a reasonable timeframe.
I have two, soon to be many spreadsheet files. There are cell references between the files which need to be updated. I would write this in a excel macro but these spreadsheets are design tables for Solidworks, a CAD system and it does not allow macro enabled workbooks. So what I would like to do is push a button and open all of the spreadsheets, accept the update workbook prompt then save and close the files.
I've seen a similar command developed by someone using the Soildworks API but updating design tables in solidworks takes ALOT of time to run compared to just opening and closing spreadsheets.I am using Visual Studio 2010 Beta 2 along with Excel 2010 Beta 2 (I like to have the new things)

Dim zAlbum As String = AxWindowsMediaPlayer1.Ctlcontrols.currentItem.getItemInfo("Album")
