VS 2010 - How To Get Real IP Address
Feb 1, 2012
In a WinForm application, if you want to get the IP address of the machine the code is running on (for instance, to log in the database what the IP address is when a user deletes a record), I would use this
Dim xEntry As System.Net.IPHostEntry = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName)
Dim ipAddr As Net.IPAddress() = xEntry.AddressList
blIP.Text = ipAddr(0).ToString()
While the code works, and it returns the correct IP address (for example: 140.139.138.137), Visual Studio doesn't like that code, and tells you that GetHostByName is obsolete, and needs to be replaced with GetHostEntry.
But if I do that, then I get back something that does not look like an IP address:
fe80::28ba:e091:1056:949f%11
So my question is, if I'm not supposed to use GetHostByName because it's been replaced by GetHostEntry, how come GetHostEntry doesn't give me the IP address?

I am working on a DLL to do PDF manipulation. In my DLL I reference the itextsharp DLL. (ie. a DLL in a DLL) In my DLL I have a form with an imagelist on it. Now here's the strange part. if I put an image in the imagelist in design mode & run the program I get this error:
Error1Could not load file or assembly 'file:{full path}/itextsharp.dll' or one of its dependencies. The system cannot find the file specified. Line 141, position 5. Error2Unable to open file 'D:VBProjectsDLL_DemoMyDLLobjReleaseMyDLL.Form1.resources': The system cannot find the file specified.

I have code a sample program. and protect it with Xenocode,It's weird That I can't get the real filesize of the protected file.the code I use to detect filename and filesize is below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim fileDetail As IO.FileInfo
fileDetail = My.Computer.FileSystem.GetFileInfo(Assembly.GetEntryAssembly().Location)
MsgBox(Assembly.GetEntryAssembly().Location)
MsgBox(fileDetail.Length)
End Sub
When it startup. It does not show the correct file size "359,833"of this exe instead of a smaller value."20480". Even I define filepath to a real path such as "C:WindowsApplication3.exe" and detect C:WindowsApplication3.exe,'s file size it shows 20480 too. seems something wrong with file.length method. With Assembly.GetExecutingAssembly() also return false value of file length.

On VB.NET 2005 and 2008, if you were debugging you could roll over the variable you set as an array and a little "+" would pop up next to the array variable and you could click it and see all of the data loaded into the array.

connected to my Arduino. Using the VB.NET (2010) GUI I request which LED I want on (via buttons) and the I2C device then sends a reply confirming which LED actually turned on (basic feedback). Ok, sounds great right? Here's where I get issues. Well when I try to read the serial data sent to VB and display the real-time stream on the GUI, a) I get a bit of a mess as an output (values are ok, just spewn across GUI) and b) when I select a new LED to turn on, the GUI data does not refresh to this change. The stream being sent from the Arduino is ok, I looked at the data in a serial monitor.

- I'm working on a windows forms application (.NET 4.0). - My form contains a 'Fast Line' chart using the Microsoft chart control included in VS2010. - The chart gets filled with about 20,000 datapoints. - My application then starts receiving market data from a server via DDE (Dynamic Data Exchange) in real-time and adds it the chart.
Note: I have no control over the server and so I have to deal with DDE only even though it's an outdated technology. VS doesn't support DDE anymore and so I use the Ndde library which works like a charm.
Private Sub StartDDE()
'first we connect to the DDE server:
Dim client As DdeClient = New DdeClient("ServerApplication", "Bid")

Lately I have been making a program (I guess you could call it a trainer), which would read the process memory to get the character's coordinates in a game. It later makes a simple map and show it in a separate windows. I built this program in VB.net, and it works surprisingly well. The only problem is the fact that the memory address where the coordinates are stored, changes every time I restart the game. Could someone please help me find a way, for the program to find the correct address by itself? If it helps, the game I am referring to is Minecraft.

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

1. Can I include a database in an exe file? - I am trying to create a small launcher application which contain 10-20 IP addresses with name, addresses, phone and email for people I help out on a regular basis. I would prefer if I could have the DB containing this info included in my launcher app, so I could carry it around on a USB stick.
2. How do I get mstsc.exe (remote desktop) to launch with an IP address from my DB above?- In my small app I am trying to add a launch button for each person. So if I am helping "person1", then I click the button next to him, and it launches my remote desktop of PC Anywhere to his IP address....
My initial thought was to use an ini file with my exe file, and modify the ini file with data through the app, but I want to be sure that there is no way I can include this information in the exe file.As I want to be able to change the connection information through my app interface I reckon I am forced to use either a SQL DB or some sort of file DB right?
