What is a good way to do networking? I tried this example, but it did not work. [URL]
how to connect two computers similar to how you would with Winsock. Also, I would like to be able to send an image, but I can figure that out later.
I created a simple desktop app (really simple) and did a network clickonce deployment. It works fine on most computers.BUT nothing on one computer (computer A). No message, no start menu, nothing. App has no dependencies other than .NET framework. If I just copy the exe onto the same computers, it works fine on all computers except computer A.Computer A has the correct framework installed. When I double click the exe it does nothing - no message, no error, not showing up in task manager, notta. I tried more than one application and it performs the same.

Scenario: 10 computers in a computer room. connecting it to a server.
I have created a program that allows me to remotely access computers on my network (not all done by me i found some code online) however i want to modify that program to allow me to connect to computers not on my network. How can i go about doing this? My program consists of a client and a server. When the server runs it listens for the client on the client side i enter the IP address and it connects so i can send remote commands to the remote system.

We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).
I'm working on an application where I'm using an webcam image. I have code that works when using the built in iSight (It's an Apple running boot camp windows 7) camera.

I am trying to connect to my remote MySql Database within Visual Studio using the compact framework.
I can successfully add a data source and preview the data within the IDE so assume that the connection is ok regarding Connection strings and remote access.
However, when I attempt to access the data using any run time control I get the following error when the table is loaded using the .fill method.
MySql.Data.MySqlClient.MySqlException was unhandled
ErrorCode=-2147467259
Message="Unable to connect to any of the specified MySQL hosts."

Also, if they are so similar then why do they exist separately?

I've two BGW with similar coding but different approach, My second BGW shows me "NOT RESPONDING" whenever i try move/click/focus to form while the BGW is running.
VB
RichTextBox2.AppendText("Some Text")

My.Computer.Network.DownloadFile(andpic, "pics/" & spliti(0) & nnum & ".png")
My.Computer.Network.UploadFile("pics/" & spliti(0) & nnum & ".png", "ftp://ftp.mywebsite.com/domains/mywebsite/public_html/Pics/" & spliti(0) & nnum & ".png", "users", "password")

I've taken out number of things that i think is causing this error Are they the cause of "NOT RESPONDING" ?
I have a web site where users enter company names to use in the rest of the app. However, recently I've noticed that similar duplicates are appearing, e.g. someone will enter EastTec Solicitors another will enter EastTec Solicitors Ltd someone else will enter EastTec Solictors (missed the i out in Solicitors), when there should only be one entry of EastTec Solicitors. What is the best way of checking the database for entries similar to what they have entered? How would you about checking for spelling mistakes as well like the Solicitors one?

View 5 RepliesI'm trying to create an enumerable class, similar to System.Drawing.Color - My goal is to have places in the code where I can define a variable as the type of my structure, then be presented a list of static values to pick from.I'd also like to use this for a property of a UserControl.I don't know if I'm using the right setup here with the class, structure, etc.I'm just trying to mimic the Drawing.Color class.I'm creating a Public Class called Person.Inside it, I have two Public ReadOnly Properties for Name and Age, their corresponding Members, and a Constructor to create a new Person.Second, I have a Structure called Persons and it has two ReadOnly Properties: Billy and Sally.[code]In my attempt, I get the full freaking .net class library in my intellisense list. Using Drawing.Color, I get a nice pre-defined list of values to pick from.No extra methods.No constructors.Just values.

I've looked around and I haven't found anything that fits my needs.I wish for the program to be able to intercept the Win32 (?) messages that are being sent to my own application, which is written in Visual Basic.As a side note, is "intercept the Win32 messages" the correct phrasing?Either way, an elaboration won't hurt; I wish for the spy tool to intercept the same messages that I would programmatically intercept with WndProc, i.e: the SendMessages and PostMessages.
I wish to make it clear that I am not seeking a program that intercepts the .NET framework events.
Edits:I can see my window and the handles of its child controls, but I do not receive any messages.I am using Windows 7 64 bit.My Spy++ version is 8.00.50727 Semi-solved; I have got a Spy++ alternative ([Window Detective][1]) to work on my virtual machine, which I am most certainly happy with, and would definitely not mind settling for. Although I am still wondering why all the "spy-like" programs I found did not work on my "main" PC... but I guess I needn't care.
Like my computer have 3 image, and this is the location of these 3 image:
C:/A.jpg
C:/B.jpg
D:/C.jpg
And this is the 3 image preview: now if we use eye common sense, we will saw that A.jpg is similar with C.jpg (just think that C.jpg is not animated) But now if i use VB.net to find the for the similar image, how can this be? (just like the searching function on computer but this is searching for similar images, and also what google images does (google image have a function that search for similar images))

View 4 RepliesI saw this in some vb.net source code:Dim sTest As String = "" & drTest("column")
I was told that if drTest("column") is nothing, then sTest will be assigned "", so it is in effect doing:
Dim sTest As String = If("",Nothing,drTest("column"))What is the downside of doing it the first way I showed?
What is the difference between using If and IIf?
I have a table which has the following Columns
