So the program I have is an overlay for a bit of software that has a main Video out. Whenever I go between forms the video freezes for a tiny bit but is noticeable. I am using the following to go between forms,
vb
Form6.WindowState = FormWindowState.Maximized
Form6.Show()
Me.WindowState = FormWindowState.Minimized
Me.Hide()
Is there a better way to cause less work for the form, making there be no lag at all?
I have some forms in my application and need to switch between them. I dont want to open another form over other form, in short I want the user to get a feel that he is working on one form only. Right now I am doing something like this but this is not what I want
[Code]....
In my project, I want the abiliity to switch between forms without closing them. What is the best way to do this? I have a "Login Splash Form" that you sign into, and then a Main Menu Form opens in Full Screen. I want this form always to stay open with the ability to open up other forms from this main menu screen as needed.
View 3 RepliesThe problem I'm having is with the .close() event. Basically I've created the below code to prompt the user when closing the form they are currently viewing.

I am making a visual basic game. And in the game I have a few instances where I want to call open a window (let's save to save the user's preferences) from a form, then I want to go from that form to another one.
Example:
The user has completed the new game page. I have the users choices in a host of string, integer, and boolean variables. Now I want to use a generic saving screen I made with a progress bar. When I open up the saving box, I want to close or hide the new game setup menu (whichever I need to do). Then when it is done saving I want the Saving bar to return and cause the new game form to open the actual game form and close itself.
So I guess my question is this: What is a reliable(or correct) way to poll for a return in form to signal it to go ahead with execution?
Second:
This is similar to the first question. Instead of keeping the first form open when I use the saving form; is there a way I can save the name of a page I want the saving bar to go to once it's done?
I want the user to enter their prefered username before they start a new game for the first time. So I poll the saved username setting I have and if it equals "username" I want the Username entry form I made to pop up, but once it's done I want it to immediately call the new game screen. I also want to use this username entry form on the options screen so that the user can change their accepted name at anytime; but I want this screen to return back to the options screen.
What is the accept way to do this? Is it done through stacks? (form information -> stack : load new page : Do stuff: load stack value -> goto)
Finally:
Do I have to keep a window open (not close it) to access the variables that I have defined in it, and have stored values too? Does this apply to hiding too?

View 1 RepliesThe scenario is i get a string sent to me that i split by a space. Any thing under 60 count when the split occurs it's fine. After that i have a problem.Now there is a lot that needs to happen before we can add this newly split array to the listview.First we need to check what the name starts with. Then assign an icon to this nick.When my server class gets sent this string. Raw Numeric 353 channel names i then send it to my nicklist class.
vb
Private Sub InitiateThread(ByVal nicks As String) Handles _server.NameListEventArgs
Dim thread As New Thread(DirectCast(Sub() DoWorkChannelNicks(nicks), ThreadStart))
thread.Start()
End Sub
Then we split the string and loop each item
vb
Private Sub DoWorkChannelNicks(ByVal users As String)
Dim nicks() As String = users.Split(" "c)

how to speed the process up?
I've copied a project from one computer to another and while I can open the project and its one module, when I try to open any of the forms, I get this error:
Quote: There is no editor available for 'C:UsersDaBoyesDesktopWattsDBForm6.vb'.
Make sure the application for the file type (.vb) is installed. I can open the forms just fine on their own--I just can't open them from within the project.
How can I check if a computer has multiple screens?And is it possible to move form to other screens aswell?

I created a background image for the form with rounded corners. I filled the outer edges and empty space with Lime color (00FF00) and then set the same transparency key in the properties for my form. It worked well, the edges were transparent and the form appeared round-edged. This was accomplished with Visual Studio .NET 2005 on Microsoft Windows Vista Home Premium 64-bit.The very same application was ported to a different platform. Visual Studio .NET 2005 on Microsoft Windows XP Professional 32-bit. All the settings are the same and nothing has been changed. But the transparency effect is not appearing on the Windows XP platform.

View 1 RepliesI have 2 listbox's, same locations/sizes (one behind the other). I have 2 buttons, and they just switch the views between the listbox's by changing their visibility propertyThe problem is listbox1, which gets populated first, displays just fine. No code in the program touches listbox2, except for 1 button that adds items. When switching to listbox2 to see the added items, the items are there (verified by debugging and hovering over the added variable), but the text that is displayed won't update. The text that is displayed is the text from listbox1.

I have an application I wrote that is in VB.NET 2.0. Works great, but I'd like to switch this application to Linq. I use ADO.NET to load XML into a datatable. The XML file has about 90,000 records in it. I then use the Datatable.Select to perform searches against that Datatable. The search control is a free form textbox. So if the user types in terms it searches instantly. Any further terms that are typed in continue to restrict the results. So you can type in Bob, or type in Bob Barker. Or type in Bob Barker Price is Right. The more criteria typed in the more narrowed your result. I bind the results to a gridview.
1) Go to Project Properties --> Advanced Compiler Settings and change the Target framework to 3.5 from 2.0.
2) Add the reference to System.XML.Linq, Add the Imports statement to the classes.
So I'm not sure what the best approach is going forward after that. I assume I use XDocument.Load, then my search subroutine runs against the XDocument. Do I just do the standard Linq query for this sort of repeated search? Like so:
Dim people =
from phonebook in doc.Root.Elements("phonebook")
where phonebook.Element("userid") = "whatever"
select phonebook
i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.

View 6 RepliesI have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans.

So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
