.net - "Find All Tiles Connected To This One" Project?
Jan 29, 2011
Remember MS Paint? The bucket tool? If you used it and clicked on a pixel, all pixels connected to this pixel that are the same are affected. The theory is, I suppose, to check if there is any pixel adjacent to the selected one. If such pixel is the same type as the selected one, check for more adjacent pixels in this one, and so on.
I want to implement something similar in VB.NET. Basically I have a 2D array map which represents the map. Let's assume there are only two types of tile: 0 and 1.Now, I got pretty much everything ready: I got my 2d map and I can tell which tile is clicked and tell what array indexes are the ones that represent such tile.Now for the "painting" process. Whenever I think about it, I can't figure a convenient way to execute such iteration. Can someone help me choosing a correct design/way/tip to achieve this?

Using the code below i will get all network interfaces wich are enabled and functional on the machine.
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
For i As Integer = 0 To netIntrfc.Length - 1
If netIntrfc(i).OperationalStatus = OperationalStatus.Up Then
[code]....
But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
[code]....

On my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

For a university term project, I'm working on a graphical roguelike (I'm aware of the contradiction in terms :P) that uses an isometric display. What I'm trying to figure out is, since drawing all the tiles is stupidly expensive and unnecessary, I'm wanting to figure out a relatively fast algorithm to determine which tiles should be drawn to fit within an NxMpx window, given that the tile graphics are XxYpx.
I'm not doing smooth scrolling for this, so that's not an issue. I'm also not worried about being perfect - a little unnecessary draw is fine, I just don't want to draw a huge amount of unnecessary tiles that won't show up in-game.

I've been trying for a week now to get a clipped tile from a sheet and draw it in either it's destination picturebox or draw it to a picturebox that will be the same size and the clipped tile and then draw it from there to it's destination. Nothing seems to work for me. I even tried using Bitblt but that didn't go very far, although I had better luck with that then the built in graphics functions. So, for now, I removed all code and decided to start from scratch again.
The only thing I got so far is this:
Dim myImage As Bitmap = New Bitmap("C:UsersSomeClownDesktopBitblitTestinasis.bmp", True
picSource.Image = myImage
As you know, all this does is load a bitmap file into memory and the second line draws the bitmap to a picturebox.

While trying to find an answer to my question, I came across a project called OTSe, which allows people to make they're own online 2d online games. The system is based on an open X, Y, Z square tile map. For the sake of easy understanding, lets say they're are 3 types of tiles. Tiles you CANNOT walk on, tiles you CAN walk on, and tiles that SLOW YOU'RE CHARACTER DOWN.The project team has created a API class for users to work with in order to develop tools. What I'm trying to do, using they're classes, is GET the all the tiles on the current floor I am walking on, and then display them in a tile grid on my form, changing they're color depending on what type of tile they are. If the tile is NOT WALKABLE, make the tile gray, if the tile IS WALKABLE, make the tile brown, and if the tile SLOWS YOU DOWN, make the tile red. I also need it to store the information of each tile, since tiles are objects, and have properties.

I am trying to update a Vs2008 project to vs2010. In one of my projects I have two controls. The controls are not being seen by the form when I open it up in design view. They are friend controls. (No code has changed since I opened it up in vs2010.) But it was running fine in vs2008.

I am working on a WPF project in Visual Basic. In some textboxes I want to limit what the user should be able to type. The sub roughly looks like this:
Private Sub Intervall_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles Intervall.KeyDown
'Determine whether the keystroke is a digit from the digit keys on the top of the keyboard.
[Code]....
If the I type backspace or delete, keydown doesn't react, so these particular cases I've handled in KeyUp.
There are two problems with this code: The test If e.Key < Key.D0 only checks whether the user has pressed the key that contains 0 at the top of the keyboard. It is also possible to enter some other signs if the user presses shift, and this test doesn't discover whether the user presses shift. I therefore need to extract the actual character that the user entered, not only which key he or she entered, and check if this character is a legal one. This is easy in a Windows.Forms project; there I can use e.Keyvalue, but in my WPF project I don't get that alternative when I enter a dot after "e".
It's necessary to solve this problem in order to do the next step: The user should also be allowed to enter colon, as this textbox describes a time that an action should be performed. If I could check the content of the key pressed, this would be easy. The problem is that the test If e.Key = Key.OemPeriod returns true whether the user pressed shift or not, i.e. whether the user entered a period or a colon, which are on the same key on my keyboard, I don't know how it is on other standards of keyboards.
I have tried hard to find a solution for this on Google, [URL] and MSDN, but I haven't managed to find any articles or topics about this particular problem. Does anyone know how to do this in a WPF project?

I am having a problem running an Excel/VBA program that has been working till this morning. The error I got when I ran a macro I wrote is: Compile error: Cannot find project or libraryWhen I check the references in VBA editor, I find the list of references to be different than when I ran it on another machine. I have some xla libraries on a server that I've linked to the application, and the libraries are being shared among my colleagues. I tried relinking the libraries but that didn't work either. Sometimes, I get another message saying the library is being used by another application.

I've just converted a project from .net 1.1 to 3.5, and I'm being given loads of warnings in the error list. The program compiles and runs ok, but I think I should probably try to at least reduce this large number of warnings.The trouble is that the error list only tells me about the first 102 warnings. Even when I fix one, the number stays at 102. So I have absolutely no idea how many warnings there actually are. If there are 150, I'd like to get rid of them. But if there are 10,000, I don't have the time to fix them all.Is there a way to see the actual total number of warnings?

I am trying to publish a project. Via the publish wizard I have published the project. So I have:Project.applicationSetup.exeand a directory application files in which:Project.applicationProject.exe.deployProject.exe.manifest. When I start the setup it does it's thing (only one question: do you want to install ...etc) and 2 seconds later its done.
Problem:
1. I can't find the installation directory... (I can find the app in the 'add/remove programs' but not anywhere in program files or ..)
2. there are a few xml and mdb files I want to include in de project (or else the project does not work).
But because of (1) I don't know where to do so. Or beter yet, I would like to include these files in the installer.3. Why doesn't the installer ask me where I want to install?

The application must have basic functionality as to: Insert new customers into the database A search function will be needed to find a users criteria entered The more advanced features would include matching certain criteria with another for example if the data in field 1 is the same then it should match this and return the results. so for example if a person has a hobby of 'football' it will return all the people with the same hobby

I support applications in VB6 and VB2003, and I'm trying to upgrade the VB6 app to VB2005, so I have three versions of Visual Studio on my pc. I ran VS2005 and opened the VB6 app to launch the upgrade wizard. It seemed to run fine until it threw an error saying it could not find the project it just created. The project I'm trying to upgrade is called MGxFromSAP.vbp. The error said it could not find MGxFromSAP.vbproj. The project file it actually created is called MGxFromSAP.vbproj.vs7.vbproj. When I try to open this project in VS2005 it says it was created in an earlier version of Visual Studio and needs to be upgraded.Did it perhaps invoke the VB2003 upgrade wizard instead of the new one? How would I be able to tell?
Should I just let VS2005 upgrade the vs7 project or should I try to deinstall the old VS2003 upgrade wizard and rerun the upgrade from scratch?

About 3 years ago i came across a vb project for a photo album, it was on online tutorial and I followed it and after some custom tweaking I found it was quite usefull. Unfortuatly the original sourcecode has long since vanished.The project was fairly easy to follow and I remember the author had a photo image of his sailing boat and a yellow labrador (just trying to jog some memories here) :).
Anyway; I have searched high and low for it but can not find it. I'm pretty sure it was on a msdn or some other microsoft forum and was to do with VB 2005 or VB 2008 edition of Visual studio.

I have a couple of NET 2.0 projects on the go, but in one of them, I can't access the "Server" object to get at its HtmlEncode property.i.e Server.HtmlEncode("xxx") does not work.
I get the following error displayed in Visual Studio design time error log: "Local variable 'server' cannot be referred to before it is declared." I have tried to add a manual reference to System.Web, but although the dll file is present, it doesn't add itself on - or at least it doesn't display on the "Add Reference" dialog as being added. BUT here is what's interesting - I can access other intrinsic objects such as "Request", "Response"...etc. All except "Server" This is only happening to 1 particular project. In other projects, I can access the "Server" object just fine.
