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?

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.
View 2 RepliesIm 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.

View 7 RepliesI 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?
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 am creating a programme in which the user searches a file by typing into a textbox. if the search terms match anything in the file, it will be displayed in the list box. I understand this may be unclear so i will include an example:If the user enters "Oliver" into the textbox, the programme will search the file for any records that include "Oliver".The records are stored in structures:[code]The user will then click the desired record (several may appear)how would i get the integer and perform simple addition and subtractions on it?
View 10 RepliesFirst my prog scan a specific path "C:music" which contain Mp3. Then it takes the MD5# of all mp3 and put it in a listbox1. Also on the formload it does open a ".txt" which also contain MD5# that goes into listbox2.Now this is what i am looking to have :When i click my button it compare each line of my listbox1 to listbox2. If , for exemple , the first line of listbox1 is already in the listbox2 then it delete the first line of listbox1 (listbox1.items.removeat(0)). And Do until listbox1.items.count = "0".

I have a program I'm trying to put together to allow my employees to submit shift reports. I'm doing this simply to make my life a little easier as this way, they will all be formatted the same. Instead of spending a large chunk of my afternoon thumbing through a bunch of differently formatted reports.
One feature that I need to figure out requires that one listbox can see what another is doing. Here, let me try to explain..
I have one list box that keeps track of EVERY action the employee does on a customers account. (cancel, upgrade, downgrade) and then a hidden listbox that JUST tracks "cancel" actions..one for "upgrade" actions and one for "downgrade" actions.
The reason behind that is that in the shift report, the all need to be listed separately. This way, I can just add each list to it's own array and list them where I need to.
The problem I've run into... If an employee handles an "upgrade" action at the beginning of the day..and then later on the upgrade is canceled, I can easily remove it from the main listbox that shows everything, however, I can't figure out how to find it in it's own listbox. The "Upgrade" box.

So unfortunately, on the shift report, it's still there even though it's gone in the program as far as the employee can see.The item in the main listbox doesn't have the same index as the item in each individual list boxes so I can't just tell it to remove the item at the same index..

I've got my first ever program and it's working. Having tested it a bit it would be helpful for the user to be able to copy the results printed in a listbox into an email or text doc. Just somewhere where they can make a note of it really.Is there something I need to do to enable it? All the google results I found were referring more to doing this in code. I literally want to be able to support Ctrl+A, the Ctrl+C straight out of the program to wherever the user wants.
View 4 RepliesI am starting to feel completely dumb when it comes to VB.Net coding. I am using Visual Studio 2010 and am trying to compare the numbers in 2 listboxes. If an item from list A matches an item from list B, I want it to add that item to List C. Once it has added the item to List C, remove those searched items from list A & B. Continue until it runs out of numbers to check.

I have this exercise which says the following: Create a form with 2 listBoxes. Add a number of items to one listBox. Create a button that when clicked removes the selected item in the first list and adds it to the second list... Also How can i create a Messagebox that will display error when nothing is selected
I wrote this code:
CODE:
I have a datagridview (parent) and a (well, several) listboxes that I am trying to create a relation with.Datagrid has master records which contain ID fields to lookup tables. The lookup tables are populated into listboxes.I have 1 dataset which contains tables for my datagridview(s) and my listboxes.I need to create the relations so that when they click on a row in the grid, it shows the corrisponding item in the listboxes as well.Problem is, a lot of the ID's in the parent table are empty... so when I try to create the relation, it blows up.
Code: "This constraint cannot be enabled as not all values have corresponding parent values." I'm doing like like so
Code:
lo_relation = New DataRelation("RelationName",DataGridTableIDColumn, ListboxTableIDColumn)
I tried to reverse it, naming the ListboxTableColumn as the parent. That allows the relation to build, but I can't set the Listboxes .ValueMember to that...I'm kind of stumped... as it needs to be a two way relationship.
1) When the parent record (datagridview) changes, it changes the value in the listbox
2) When the Listbox changes, it changes the "value" in the parent datatable so it can be updated.
Would I resolve my issue if I populated the parent with a "default" ID in each field (say 0)... if the database value is null? And furthermore, populate each lookup table with a "blank" default value as well? i.e. First record is ID = 0, Desc = ''?
I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.
View 1 RepliesI have almost completed coding moving entries between listboxes. My only hangup is: when I trigger the dragdrop event I get the target listbox x,y coordinates. I need a way to convert these coordinates to an entry number so that I can insert the source entry in the proper place. Any one have a solution?

I have four list boxes, side by side. I've got a huge list of files that the program scans through and if (file insides) = (this) then; else if and etc. I know that part is working. The problem is actually the list boxes themselves. The reason I know this is:
I have four listboxes side by side, only the first one shows data, but if I delete the first one from the form, only the second will show data, if I delete first and second, the third one displays data, and if I delete the first three, the last one shows data. The problem is they wont display data at the same time. I was talking with someone else and they said I needed to change the IDs and I should see that option somewhere near the "Name" section. I use Visual Studio 2010... I don't see any IDs option to change. on how I can change this ID or maybe something I have to do to get these listboxes working?
How do I parse this and add the names and IDs in Listboxes ?
