Anyone have any examples, or source code or SDK's that are FREE?I'd like to setup a simple voip program to play with.Was curious whats the simplest way of doing it, using UDP across an IP.I planned on having a server program, as i'd want multiple clients.My question is, how can i stream voice, without using alot of bandwidth with minimal delay between talking?

View 2 RepliesI 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.
Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.
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?

View 1 RepliesI know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

Due to use postmessage tow times, I want add a delay (50) between tow postmessage(), and my timer interval is 1000.

I failed to get any interest/response with this question on the VBExpress forum. Surely most of you have to write help documents to go along with your programs. I have used HTML Help files for years to support my programs and before that WinHelp but in 2002 MS indicated time change to Microsoft Assistance Markup Language (MAML). I am a little behind. Google hits for the acronym or full title are minimal. What are you guys using today?
View 3 RepliesI have a preloader app that runs before the Main application and performs an Update check.. (and then installs the latest update) it's come in very handy at the current client I'm at as there are going to be several hundred installations of the App on site.. Also it's a Live Development.. (One app that handles the Full Plant Monitoring and maintenance) .. But that's not the problem..
The Preloader simply checks on the server if there's a new Update, Copies it down and then runs the Main app.Now there are several Configurable routes through the app: Quick, Skip, Auto, For now the Default is Ask.. and in this mode, if there is an update, the Preloader will ask if you want to install it, if not it will wait 10 seconds and start the Main app.
My problem is If there is no user interaction with the Preloader, windows thinks that it terminated incorrectly, and throws up one of those "This program has stopped working" (similar to image below).
If the user however simply clicks the Done that clears the timer, or clicks the Yes/No for the update, no problems.

So the problem .. If there is NO user interaction, Windows (XP Sp2 mostly) thinks it crashed.What can i include to let windows know that the application does not require User Interaction.
I have a project that runs perfect under windows xp. Now I have tried to run it under Windows 7 and got there a lot of exceptions under Immediate window.

I found this really cool page that allows you to hook up facebook into your site: See here

I want to be able to call this iframe in my page (I am using ASP.NET) and I want to be able to set the visibilty based on a variable and most important I want to be able to change the src of the iframe based on a string that is build up by variables to change the "www.EXAMPLE.com" to another URL based on the location of the page.
In my program I have a tab control with 4 tab pages. In the second tab page there is a lot of controls (about 50! includes buttons, labels, combo boxes, textboxes, option boxes). When user opens the program and want to navigate to tabpage 2 there is about 2-3 second delay showing tabpage. This problem only occur the first time, after that it just shows the page fine. I am not sure what is causing this lag but the program seems buggy and slow to user.

View 4 Repliesto some server via an UdpClient. However, I need to make sure that all commands send are separated by a 1 second delay. If there is no delay, two commands send within this 1 second timespan will not be received both; only the first or the second command will get through.he commands are sent in a background thread at the moment, because it might take some time before the command is sent. I keep looping until the command has been sent, like this:

Public Sub Send(command As String)

View 1 RepliesIm having some wierd behavior on a bound form in vb.net 2008. I have setup a client form, with another tab that has contacts for that client. the contacts tab has a binding navigator at the bottom, so the user can move amongst the contacts. all fields on that form are bound to a bindingsource called bsContact, using a table adapter called "ContactTableAdapter"
if i have a contact already saved, and want to modify the contact info, the form binding doesn't seem to recognize that i have changed the value of a textbox on that contact.i would think that if a textbox is bound to a bindingsource, then if the value of that textbox changes, the bindingsource would know about it, but it doesn't. The dataset.HasChanges returns false, and my save wont happen. (see code)so, when i hit the movenext on the bindingnavigator, it changes to record 2...i change a value on a textbox...i hit the save button on my form....no update will happen.
Update: I noticed that if i am on the tab with the multiple contacts, and i change a textbox on the form, then i MOVE TO ANOTHER RECORD, then the dataset recognizes that there was a change, and the update happens. Why doesn't the textbox immediately notify the dataset that a change is happening?

I got a function that reads memory of another process and then uses it in different ways. To prevent the GUI from lagging, I start a new thread and executes the code in it. It runs fine, but after a while, aprox. 20 minutes, the applications stops to work and an OutOfMemory exception pops up. The thing is that the memory use of the application isn't higher that 10mb and I can't notice any high increaments either. I have tried everything to find out what is wrong, but it seems to be impossible.
View 11 RepliesI am currently in the process of writing a demonstrative program that will generate a string of 9 random numbers in a textbox. Now my basic knowledge of VB 2010 allows me to do this but my goal is to delay the generation of this number sequence until the my progress bar has progressed to the end. How can I insert a delay after my button activates my progress bar/timer without stopping all function and usability of the program all together. The basic wait function seems to lock everything up for the allotted time and then the number instantly generates and the progress bar begins.

I just made an auto talker but i wanted to know if its possible to make a random time before it start talking. Exemple: Instead of just talking every 2 seconds, make it random between 2 - 8 seconds so he can talk at 2 seconds then the second 7 seconds then 3, 5, 6, 7, 8 etc......
