A while ago i did a small VoIP chat for LAN-network where i used TCP protocol.But due to the overhead on TCP (causes major loopback in the sound) i'm trying to change to UDP, but got some problem.I used BeginAccept to add new clients to a list, but i can't use BeginAccept unless i use "Listen" first.But UDP dose not have the "Listen"-function, so i'm kind of stuck.(This is on the server-application)Here is most the code i use for the TCP version

I am trying to change the cursor type to a crosshair but am having no luck. The program I am writing initially starts up as taskbar notfiy icon. Once one of the menu items is clicked the mouse cursor should change from an arrow to crosshair. This should remain like this when the mouse button is pressed again, held and then released and then it should go back to being an arrow cursor once again.To start off, I wrote the following code:
Private Sub changeMouseCursor(ByVal sender As System.Object, ByVal e As EventArgs) Handles DisectMyScreenToolStripMenuItem.MouseLeave Cursor = Cursors.Cross End Sub
This does not work but do not understand as to why this is. Visual basic 10 on Windows 7 SP1. dot net framework 4.5 Beta?
if its possible could i temporarily change the inner code of a program instead of using a timer or multiple buttons ex: i have a BUTTON1 set to open a webpage like [URL]how be able to do something like this
Private Sub BUTTON2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click if textbox1.text=1 then button1.code=me.close
I have an image that is using an indexed pixel format. I can't load such an image into a graphics object using loadimage. Ultimately, all I am trying to do is to overlay one bitmap onto a different one, neither of which will be visible for some time, if ever. That looks like it can be done fairly easily by loading the BMP into a graphics object, then drawing the other image onto it. However, that would require transforming the incoming image from an indexed pixel format to a non-indexed format.

I have created a dialog box which opens when you click the options menu item in the menu stip control, I have customised this dialog box so the user can change display modes and so on but now I want to be able to change the language of the entire application as in from the default English (american) to French, German and so on.
When the user changes the language selection I want the text in the menu bar, the title of the app and the text of whatever is in the text box of the app.

I am having in VB.NET 2010. I am writing an app to change the background wallpaper kinda a little project I am making for my wife's grandma. It is a multiple wallpaper changer to change the wallpaper based on a list of images she adds. Anyways! I have everything setup except the fact that it doesn't change the wallpaper...
This code here:
Public Declare Auto Function SystemParametersInfo Lib "user32.dll" (ByVal uAction As Integer, _ ByVal uParam As Integer, _ ByVal lpvParam As String, _
[CODE]...
Will NOT change the wallpaper but the same code works in VB6 I tried it because I have made something like it before in VB6 but it was a game that changed the wallpaper. Anyways, using the above code in VB6 works(well with a change to the SystemParametersInfo declare to work within VB6. But it doesn't work in VB.NET. I have NO IDEA why everything gets set in the registry just fine from VB.NET but I just cannot seem to get it to update the wallpaper...

I have created several small applications that use my own DLL. The problem is, this DLL is constantly changing. My current solution to this problem is that I have a Setup project in the class library solution that creates and registers the DLL. In all my applications I then have to open the solution and re-reference the newly created/registered DLL. Then I have to re-compile their setup projects, uninstall the old applications, and then re-install the new application.
There has to be a better way and I'm just not sure because I'm fairly new to all this. I have looked into ClickOnce but I don't think that will solve my issue as I cannot publish a class library. I have looked into checking version numbers but I must be doing something wrong because it doesn't work either.I understand that once a DLL is created and being used in an application it should essentially not be touched. I do not have that option in this situation. It is constantly updated. Done.
Edit: The DLL is not constantly changing during runtime but it is constantly evolving to allow more functionality and detail within the other applications. Also, one big thing I guess I should have mentioned is the Public interface is constantly chaning - usually adding new methods.
