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()
setip()
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?

I have a vb.net project which i have inserted pictures and video. I inserted a video clip using the Windows Media Player control and it does work. The issue i have is that i can't move the program to another computer because the pathname for the video will be wrong. I know i could change the pathname when i move it but this is not practical because i need to present this program. Does anybody know how to make the video accessible no matter what location the program is at?
View 6 RepliesI am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

On the server I want to be able to receive the data on another port (E.g. 8888). Is this possible?And final question is. What protocol should I use for this purpose TCP or UDP.

Currently have a program on the market and just did a major update which 100s of people downloaded, the problem is that that update had a major bug which made it crash. So quickly got to work to fix the bug but everytime I connect my software to the FTP database I get this Error Message:
"The underlying connection was closed: The server committed a protocol violation."
I triple checked my code. Everything is right One minute it was working the next minute it wasn't,My buyers are getting very frustrated and I've had to cancel all orders due to this., The bug in the update software which I have now fixed but this other bug to do with protocol violation.I havent tested if its just now my computer that the error messages comes up or it happens on others.I've tried 3 seperate FTP servers and all the same results?
how can I get the protocol and the domain form a string?
I think I should use regex for this?
Is this correct or is there a better solution?
If this is correct what should the regex code look like?[URL]..
