I'm broadcasting a simple message to ..*.255 (changing to 255 the last part of my ip) and i'm trying to listen to it. the code returns no error but i'm not receiving anything. In wireshark I can see the broacast is sent correctly, but with a different port each time (I don't know if that's a big deal).
Here's some parts of my code.
Private Sub connect()

btnsend.Enabled = True
btndisconnect.Enabled = True
btnconnect.Enabled = False
receive()

I have a program running in many machines in a network. The program reads a Sql database, and there's a table showing one table in a DataGridView in each computer from the same DB stored on the server. The same table in all the computers. What I want to do is, every time one computer changes something in the table, to update every table in all the computers.
Every program writes an entry in the database to know that they are connected to the DB. So any program can know who the other computers are.
How can all the computers know that there was a change in the table? (the idea is the get the changes quickly)
I have some experience creating programs that use tcp to transport information from a server computer to a client computer and vise versa. However, I am unable to create udp server/client programs with visual basic.net .

View 1 RepliesI want to be able to kinda like have a timer that will get an image off my Hard Drive, and upload it online, so that all I'd have to do is download the image, even if it's been written over, I want to be able to broadcast an image from my hard drive, using only my IP Address.
127.0.0.1 is my IP Address.8888 is the port.Somthing like if you were to goto http://127.0.0.1:8888/update.html or Update.Jpg If YOU were to go to this address on your machine, you could see the image... Of coarse, it will probably be an image of which I was able to get from Printing my Screen image, and then saving it as like C:Test.Jpg, but the Timer would get my Desktop Image, or Print My Screen and Save it and Overwrite the Test.jpg image on the C Drive... Ya know what I'm talking about?

Now as you can see it is sending the textbox1 text and then pressing enter then sending textbox2 text! Theres quite a few problems in that but before i discuss note: This code is in a Timer. Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!
Are there any good books out there that will show someone how to set up a form using Visual basic that will take information and send it to the server and then send a recipient an Email?

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).
View 1 RepliesI have a filter that is used to populate a grid view and the url will conain: /example/grid?value1=1&value2=2
It will then have a link to page 2, which allows them to edit something.I then want them to click a link that will send them back to the gridview under the same parameters of: /example/grid?value1=1&value2=2
Is this possible? How do I hold on and fill in the URL values so it knows how to refill the grid view accordingly?

I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should. This is the code to send the string and my attempt at making it replace the () in the module
