The short story is that I have a 5.1 audio system that is linked to my pc and I would like to make a tool to help me to transmit audio from my laptop to my pc to be played back.
I have a home network provided by a wireless router. (Bandwidth is about 54 mb/s so that shouldn't be a problem)
Router ip : 192.168.16.1
PC ip : 192.168.16.100
Laptop ip : 192.168.16.101
I am developing an application where in I need to stream audio and video in the local area network. There is calling option from my application where users can call each other(audio call or video call) in the LAN.
I'm developing a standslone system for my school project. I'm developing an audio management system which allow user to add audio files itself into database together with the audio information such as artist name and album year. I just started it few days ago and face some problems.. my song in the playlist wont continue to play after 1 finished and i need some idea on how to store the audio files into database ... in blob types may be?
Heres the screenshot and codes
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bt_add.Click
I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.
Im trying to capture the audio played on my laptop. so i have searched the internet and found a source code for doing exactly that. the problem i have is that my audio device is not listed in the dropdown box (see picture) but it does when its run on windows xp (im running windows 7 x64) the goal of this application would be to capture my friends radio stream and save the individual played mp3's to a loction on my hard drive.(yes i have permission) i have included the source code so perhaps some 1 could have a look at it. (source code)[URL]
I have a database application developed around Access with VBA,I have used the Speech SDK and developed an application that in conjunction with MSCOMM 6.0 library calls into a remote IVR system.It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one problem;I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.
I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well). This means that I must route the system audio output to the SR engine audio input. It seems that I must use an InProc SR instance - however in VBA that type is not recognized - since the shared SR uses the microphone as input by default. there is some statement to the effect that it is difficult in Microsoft's Help file. I'm unable to set the SR audio input to the modem output stream in VBA.As needed I can accomplish the C++ interface using an ActiveX object or a DLL to expose the missing API to VBA?
Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:
I want to be able to send a copy of the currently opened form to a number of remote PCs every couple of seconds and be able to view the form as it is received.Although I have been programming for a number of years, I have virtually no knowledge of reading and writing image data.
In my project, I got a page that creates guest users for a number of products chosen.Basically you tell the application how many users to create for each product you choose.When you click 'Save' I generate the guests, save their username + password (before encryption) in a csv file that I transmit at the end of the process, and finally redirect the user to the index page.The problem happens at the file transmission and the consequent redirection to a new action:
Private Sub DownloadCsv(ByVal csv As List(Of String), ByVal filename As String) Dim sb As New StringBuilder() For Each Str As String In csv
[code]....
What's happening is the page transmitting the file to the browser and never doing the redirect that follows.I read a bit on the matter and found out that once you add an Header to our Response object and Write a file, it will automatically close the Response. If I'm wrong, please correct me.How can I make it possible to transmit this file after the user has being redirected to the Index or Redirect to the Index after he either saves or cancels the file download?
It's been a while since i've posted. Happy Valentine's day! Requirement: I would like to interface my .NET application to a "virtual webcam driver" for the purposes of SENDING image frames. I'm happy to use an open source .NET or COM component if that exists or indeed implement a "webcam driver" from scratch if someone can point me in the right direction. My first priority is the functionality.
My second priority is low dependancy on 3rd party libraries and tech (aside from .NET of course I'd prefer not to involve directshow if possible?
I currently have a program that, when I select an option from a drop down menu, will transmit a character to a microcontroller. I then have to click another option after 10 seconds to send another character. What I would like to do is modify this program to transmit one character for a period of 10 seconds, then transmit another value for another 10 seconds and so on for a defined period of time, say 30 seconds in total.
I need some information on broadcasting front. I have a program which gives data every few minutes to my friends. The logic is data is prepared on a local computer, the file is then uploaded to my webserver and then the programs at friend's end download the file and process it.
Though the above logic works, but its plagued by time delays, uploading & downloading basically. Is there an alternate whereby the program on local computer which prepares & uploads file is able to broadcast data and client apps can read that data and work on it. For e.g. if you see apps that show live stock market data, the data is refreshed for so many stocks every sec. They use some other system similar to broadcasting I guess. In-order to transmit data fast how can I go about it?
I would like to know how can I transfer some data bits from one location e.g. Location X to the location Y. I am already moving MS (mobile station which I take as an image) from one location to other. Now I want to check or you can say add some data while MS is moving and make it reach successfully to location Y as I already can do with MS movement, mean to say data transmission along with MS and on that basis I want to find handover failure rate and if any data loss during the data transmission from x to y location. And check if the data delivered is successfully reached to location Y from Location X, check bits transmitted and bits received
how can i play the audio after the previous audio play is finish by using directx.
assume i have audio1.wav and audio2.wav.
i play audio1.wav by this code.
audio1 = audio.fromfile("D:audio1.wav", false)
how can i play audio2.wav after audio1.wav is finish? without use any button or signal. just depends on when the audio1.wav is finish, then audio2.wav will play automatically.
i wrote small programm based on joyGetPosEx which read ION Drum Rocker commands as gamepad events and converted it to midi notes signal to MidiYoke or other virtual midi cable.With this program ION Drum Rocker xbox360 drums with cymbals can be used as midi device for PC. Also if edit source for read another command can be used any gamepad device as mididevice.If any someone have ION drum rocker drumset then try to test this program.
I have some issue with it, drumset do not transmit any commands which can be used for sensitivity of hits. But drumset have some sensitivity of hits if connected them to xbox360 console. Maybe problem in HID gamedevice driver, or joyGetPosEx?
I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.
I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try ' We need to keep this stream alive to prevent other applications gaining access to the lock mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).
I have a problem I want to make a server and client where the server is password protected and will make the client display files/folders in a designated folder which will be in the server's current directory and the client will ask what IP and password to connect to and if the password is correct is allows the client to access the files/folders in that folder in C.D. of the server and the client can download any file within the folder by clicking a button, yet don't even know where to start.
I have all 66 books of the Bible in audio format. MP3 I believe. I want the users to have a choice of either reading the book of Romans or listening to it.
I've tried to use this and I got all the errors gone but two
Private Sub buttonSaveAs_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonSaveAs.Click If listViewTracks.SelectedIndices.Count > 0 Then
i keep getting this very wierd problem were i put in audio into my forms and (Design) but when i put in a 4'th song, it stops working and comes up with a error. I havn't limited my audio to how much songs i can play but for some reason it just stops playing them. This code below is the code i use for this form
I would like to loop through audio in VB.NET. Here is my code: While blnAlert = True My.Computer.Audio.Play("C:cat_1.wav") End While But it freezes the app.
I have put some wav audio on the resources. in my form, i have a label. i named the label as s1f1 and s1f2. now i want to play the audio according to the label click. if it is click then the audio play. i dont to put a line of code in every label. assuming that there is a lot of label, then it will be a waste of time. so how can i play the audio, by only write a several line code but for all of the labels.
I just wanted to be able to detirmine if the file that the user selected out of an OpenFileDialog is an audio file (mp3, mp4, wav, etc.)
I know that I can just use the filter property with the OpenFileDialog box, but I'm sure that there must be an easier way to validate the file the user chose and see if it's an audio file.
