VS 2008 - Voice Recording And LAN Stream
Jul 19, 2011
I am trying to make a program that can send voice over LAN. I already have the connection between the computers working, but I can't really seem to find a way to actually record + stream sound.
I've found out that I can use
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
and then
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
mciSendString("save recsound *PATH*", "", 0, 0)
to save and record sound.
But I haven't really been able to find any documentation on that function, so I haven't been able to find out for myself, how I can send the recorded sound over LAN, instead of saving it on the computer.

I have a voice program that can compare voices to stored voice files and identify people based on that. It's not the most accurate thing, since being sick or other weird things can make it fail, but it does work for the most part. I was wondering if there was a way to keep the voice recognition running during an unlock and wait for the person who locked it to come back. Upon giving the command and voice verification, if it passes, the computer is unlocked by my program. Is there anyway to do this in VB.NET?Summary: Can a program unlock a computer after it's locked?

I have seen that there are many "Mouse & Keyboard Macros/Recorders" out there & I was wondering how they are being created in visual basic. I have looked within the Microsoft forums, but havent really seen any specific coding that works for the kind of recorder that I'm trying to create.

Basically I'm aware that using the code shown below you can get the default 'microsoft Sam' voice to work and read a textbox for example.

in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing
[code]....
How can I write the resulted stream to be sure I can read it again later?

I'm sending an http request through a proxy using tcp, and then using a streamreader to read the netstream...The streamreader is supposed read each line up to </html> , however it doesn't seem to be waiting for the packet/response to be fully received, as it always returns only the first 5-10 lines of HTML.If I add a breakpoint at the line "Using sr", and pause it there for a few seconds and then continue the execution, it will return the full HTML up to the </html> as it should.This is the part of my code which reads the response.
Dim sendbytes As Byte()
sendbytes = System.Text.Encoding.ASCII.GetBytes(ReqHeaders)
netstream = tcp.GetStream()
netstream.Write(sendbytes, 0, sendbytes.Length)

I am developing a VB.NET 2008 application, consisting of a main EXE application and several resource DLLs.
I need two functions for the DLL:
1) one function to get a list of all files in the resources of the DLL.
2) one function to return 'by name' a resource file as a System.IO.Stream type.
NOTE: The files will not be "Embedded Resource" (this doubles the size of the DLL), so I think cannot use 'GetManifestResourceStream'.

I currently use:
Return New System.IO.MemoryStream(My.Resources.MyFileName)
but I want it to be called by name.I am adding the resources using the VS 2008 "Resources" tab, from the My Project screen, I'm not manually editing Resources.resxAs I said before, it works with:
Return New System.IO.MemoryStream(My.Resources.MyFileName)
but I need to get the resources by name, which also works by using
GetMAnifestResourceStream
but this requires to set the resources Build Action to "Embedded Resource", which doubles the size of my DLL file.I currently use "None" as Build Action, but I can use any Build Action that does not increase the file size more than the actual resources size.

I have a dataGridView and tied it to a button that saves every time you click it. and every time you click it, I want to write a line to a txtfile that displays how many records were changed and the date that they were changed. Everything works fine but every time a save has been made it over write the previous entry on the text file. Here is some of the code.
If changes > 0 Then
MessageBox.Show(changes & " changed rows were stored in the database.") ' changes shows how many entries were changed
swDate.WriteLine(changes & " record changes on " & entryDate) 'entryDate is formated as date with value of "Now"
Else
[code]....
I am getting the right results in the text file except it over writes previous entry's so there is only one entry saved in the text file at any given time. I want it to keep building the text file so every time something is streamWrited the previous things in the text file stay there and it add to it. Looking at my problem I cant really justify or implement a For Each..Next or a Do While..Loop. My vb knowledge is limited so go easy on me.

I'm trying to write code to download from an FTP site. I got it to work in some cases - mostly text files, but when the reader reads a value greater than 256 it seems to have difficulty. Right now I'm trying with a ZIP file, and the file downloads, but always says, 'File is Corrupted' when I try to open it.

I need to read strings by stream! Is this possible? I've been searching for quite a while now, without results.So what i have is an application which gets song lyrics. The lyrics come in a string and i need to separate the string into multiple lines. Just to make that clear, lets say that im getting this text and put it into a string:
Bla bla bla..
Na nana na
And in string format = "Bla bla bla... Na nana na" but what i need to do is separate them into its original, line by line.I created an for each loop which looked for upper chars and when found, create a new line. But that didn't work out so well since the lyrics are written in proper english, using the upper "I" everywhere. So i created a new loop which ignored "I":es if they were followed by a space/blank " ". That didn't work either, it skipped some sentences.

I have create a Stored procedure which is creates the Streaming Data Base.This SP needs to have the path on which will put the mdf files (and some other things).Until now i was run this procedure after i first create the above mentioned path.Now i want to run the same procedure without interference in the server.So I give the following path in order the procedure to execut it and understand where i want to give the path guide.
\ServerNameSharedFolderNameSQL
The stored procedure takes the path and tries to go to the folder of 'SQL' in order to do her job.But in this point i receive an error which says:CREATE DATABASE failed. Some file names listed could not be created, Check related errors.
-I'm Cheking the way of puting the path and it is absolutelly right, I mean accepted from the server machine and from the client machine as well.

I am using StreamWriter and StreamReader in VB.NET 2008 Express to read and write ASCII text files. When I create the file and later read it, there is no problem, because I use System.Text.Encoding.UTF8 on both the write and read sides, so extended text is handled without problem. But sometimes, I have text files come in that are just straight 8 bit ASCII without the Unicode BOM... and they get a lot of junk when I try to read in anything with extended ASCII characters in it. It seems like the 8 bit extended characters are translated into multi-byte codes, and since they are filenames, of course, that doesn't work. Since the filenames just have straight 8 bit ASCII filenames. I have tried all sorts of encodings, and nothing seems to work.
The most common character that causes a problem is an "a" ... it is used in a lot of proper names. The funny thing is that sometimes is seems to workout... is there a way to read these types of text files? Some way to just tell StreamReader not to decode the text, just treat it as straight plain 8 bit ASCII text (with the old IBM PC mapping, I think). The one thing that works is to manually edit the input, replacing the extended characters with their un-accented partner and then renaming the files to match the new spelling. Maybe I should just go to read them as byte input and breaking the lines apart in my code.
