VS 2008 MciSendString Save Wave File
Jul 19, 2009
I have a created a small application that records and plays audio. However, my application needs to save the wave file to the application data directory on the users computer.The mciSendString takes a C style string as a parameter and has to be in 8.3 format. However, my problem is I can't get it to save. And what is strange is sometime it does and sometimes it doesn't. However, most of the time it failes. However, if I save directly to the C drive it works first time everything. I have used 3 different methods that I have coded below. The error number that I get when it fails is 286."The file was not saved. Make sure your system has sufficient disk space or has an intact network connection".[code]

I am trying to convert a mp3 to wav and I need to know...What is the very first thing you see when you open a wave file up? the 2nd, the 3rd, 4th and so on. Is it the riff header or the riff header contents(ID, size, Type). I need this info for a Regex string that would look something like this...
'Frame/MaxFrame (PercentDone%) | CPU time/estim | REAL time/estim | play/CPU | ETA
Private Shared _regLine As Regex = New Regex( _
"(d+)/(d+)D+(d+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d.]+)D+([d:]+)"

So, I re did my project in VB.NEt instead of C#. So, I put all the sound files in the resource files. I made a routine to play the sound file but it says that to make sure the sound file exists. Which it does because it played in the resource manager.Here's the sub routine to play the sound:
Dim sndplayer As New Media.SoundPlayer
Public Sub TestSound(ByVal snd As String)
My.Computer.Audio.Play(snd)

I am trying to figure out the numSamples in this:The canonical WAVE format starts with the RIFF header:
0 4 ChunkID Contains the letters "RIFF" in ASCII form
(0x52494646 big-endian form).
4 4 ChunkSize 36 + SubChunk2Size, or more precisely:
[code]....
This works fine for getting the wave file info, It just doesn't display the numSamples which I need.

I have used DirectSound to play a wave file in my application using the function CreateSoundBufferFromFile. It works perfectly.Now I want to play files from a resource dll file. I have created 1n2v32.dll file having nearly 100 small wave files named 1,2,3... I can play them using LoadLibraryEx, PlaySound & FreeLibrary.Now, I am trying to use CreateSoundBufferFromResource function from DirectSound api to play these files. I get Run-time error '432': File name or class name not found during Automation operation I used the following code to create the buffer.
Set LDSB = LDS.CreateSoundBufferFromResource(App.Path & "1n2v32.dll", "14", BufferDesc, gw)

How could I...
- Increase the frequency of every part of a wave file by a specified amount of Hz
- Increase/decrease the length of a wave file without reading it faster = changing the pitch
- Combine many wave files into one

I have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for. I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.

My question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.

I'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

All my files are .gif files and all have the same format. However, some of my 'objects' are located at different positions on the image. I would like to store the position in a Tag and save the Tag with the file. I took a simple approach to it but its not working. This is what I did..
dim pathload As string = "C:myfile.gif")
dim picViewer1 As New PictureBox
Sub graphlocationsave()
[Code].....
My MsgBox is blank, there is no data... I know the data get store in the Tag, but I do not know if its not saved, or I am not retriving it correctly or if this is the wrong way to do this altogether ?
