I have a little problem whit passing delegates. I have a program that load some data from internet. When the loading starts i create new thread for this. What I want is, when the loading ends I want to call one procedure in my form. So when I initializing class I want to pass that procedure. But I have problems with implementation. This is the pseudo code off my class and how it should look like.
Public Class GetArtistInfo
Public Delegate Sub RefreshInfoSub()
Public RefreshSub As RefreshInfoSub
Public Sub New(ByVal RefreshInfo As RefreshInfoSub)
RefreshSub = Address Of RefreshInfo
End Sub
I'm developing a management program for a driving school, where information about all students is stored and accessed.
The thing is, this school has got two branches, so I need some way for those two computers to share files with each other in order to keep a common database. I would like to use the same program in both computers, to keep simplycity to the maximum.
I know it's using TCP, but I haven't got the lesser clue of how i can achieve that. I've looked around, but I haven't found much of how to acchieve something like that. The files both computers would be sharing are text files.
About the IPs, I'm thinking of using NoIP or one of those to always know both IPs.
I am reading data from a mysql database table.I have populated a dropdown with the relevant slections, i want the rest of the form to load data once i select the plate number .[code]...
i have a program that calculate a download and up load speed for internet , and i'm doing this by the following for download
1. but the whole code in a timer with interval 1 second
2. calculate the total byte recieved and store it in a variable (s)
3. calculate the new value of total byte received and store it in (s1)
4. s2=s1-s
5. s2 represent the difference in an interval within 1 second is that a download speed ?
i test it with downloading some files from internet using mozilla firefox the values is so close to each other but is that the right way to measure the speed ???
I have a dynamically created webpage(in a string) and I save this locally to a file subsequently load it up to view it in IE, is there a way to get Internet Explorer to view the page from memory without having to save it first.

I wanna make a chat program over the internet NOT OVER LAN i found alot of examples but it's all about LAN networks chatting but i want a chat program for the internet chat
I'm trying to create a program that will disconnect/connect you from the internet.Example:When I press F10, I get disconnected from the internet. When I press F11 It connects me to the internet.
First of all let me say that while I was knowledgeable enough to create my program using VB-10 express I am by no means fluent in 'programming' speak .. so if you choose to help me please don't use technical jargon.. just explain as if you are talking to a 6 year old ..
Anyways I would like to give my program to some friends either by Email or via the internet (I have a website [url] (it is a wordpress blog) but I have no clue as to how I would get it onto my site.
I have attempted to Email the files .. first I had to change the file extension because Email would not send an .EXE file.. Then I tried to ZIP the files and send them via WINZIP but my recipients kept getting 'unable to open file' messages.
I am making a program that gets files and folders off the internet.I want to make a window simular to a windows explorer window only these would get the files online.My problem is href tags for each one of the nodes and then get the files into the listview control. [code] I can get one node but after that I can't figure out how to get the other nodes to work.
had 3 courses in computer science 10 years ago and decided to go into economics. After a 6 year and continuing career in economics, I decided to dabble in code to assist my economic career. In this pursuit, I have developed some neat things, but I have a simple problem. I code an application, hit build, hit publish, receive a setup and manifest, then put it on my usb drive. Plug the usb drive into another computer. Drag the setup and manifest to the hard drive, hit the button, a graphic regarding Launching Application comes up, then immediately a window comes up stating:
Cannot Start Application.Cannot download the application. The application is missing required files. Contact application vendor for assistance.
The errors stem from the manifest file. It says downloading the file (file path) Hello.exe.manifest did not succeed. It then follows with 3 lines of filepaths for the Hello.exe.manifest.
I am running VB 2010 express. I made a slot machine game for my mother for her birthday one Computer A. I moved the published files to Computer B as described above to test before giving to my mother. The game isn't too important at this point because I tried to test whether the game itself was the problem or if it was my error in lack of knowledge of how to deploy. As such, I created a program called Hello. In Hello, there is simply a form1 and a button1. When clicked, button1 displays a messagebox with some text. Not a rocket science program.
My intention is simply this:Allow the Hello program to be put on another computer via a USB drive and then installed.The two computers are not networked and let's assume the second computer cannot connect to the internet. When I go to the wizard, I select the location I want to publish to. In this situation, my desktop.Next, I select CD-ROM/DVD-ROM instead of UNC path or website. I don't know what UNC path is. I presume CD-ROM/DVD-ROM would be similar to USB drive in that it is a removal data storage item.I chose that the application will NOT check for updates.Finally, I receive this:The application will be published to:
file:///C:/Users/ComputerA/Desktop/
Where I find the files, put them on the USB drive and try to install on Computer B.Also, for more information, I can use those files on the originating computer and they do SUCCESSFULLY install and I can use the application. I have not figured out why it will not install on another computer.

In class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic. Now my program doesn't recognize one of my forms when i try to access the design view of it. I hit run for the hell of it and the program runs with errors of course but the form1 "the missing one" shows up with all the buttons etc and i can use it.

i have a audio program that will play some mp3 files from a folder. but the audio files together take up about 1 gb. it is possible to let my program download the files from the internet after it is installed on a computer. to a specific folder..?
I'm using Visual Studio 2008 and developing a VB.NET application. I'm having strange lockup problems with my program, but only when Internet explorer 8 is opened.
When I cover my form with another window and then uncover it, I find that it has locked up. My program has no references to IE and the only thing it even has to do with IE is using Process.Start with a web address.
My program works fine and exactly as it should, but only when IE is not opened.
Does anyone know why a program would lock up only while IE is running?
Edit: I've done some digging and I've found the offending thread in my program. I don't know what starts this thread or what it does, but when I kill it, my program no longer freezes. The thread is one of the CreateApplicationContext threads, here is the last few items in the stack trace of that thread.

Late binding is not allowed and that's how we want it. Depending on whether our program is running on a LAN or the Internet, we need to dim an object as one of two types. We use an if...then statement to ascertain whether or not we are running on a LAN or the Internet.
When we declare our object inside the if...then statement, we have declared in the wrong scope and cannot use the object. When we declare it as an 'Object' type and use DirectCast inside an if...then statement, we receive a late binding error. How can we get around this problem without turning off Option Strict?
At the moment I'm developing an application (Similar to Swiftkit.net's) that will aid users when playing Runescape.My next major project on the program is to Make a highscores look-up. (If you dont know about the Runescape highscores, HERE)Now, i want to grab data from that webpage, and add it to a form on my application. The form in particular, will display a specified persons levels on that form under labels.First of all, i have NO IDEA on grabbing stuff from the web in VB. Second, i have searched far and wide for something similar, but everyone that has something similar is not very willing to part with their hard earned code.
