I do this in my code, capturing a frame from camera, opening a UDP connection, and sending frame data:
UDP_Client.Connect(Host, Port)
Dim sendBytes As Byte() = Data
UDP_Client.Send(sendBytes, sendBytes.Length)
I do it every 400 ms.Is it streaming video?
In my project I am capturing frames using a camera. The frame resolution is 1280*1024. Now I wanted to copy the same captured frame i.e contents of buffer(1280*1024 size) into an another buffer which is of size 1024*1024. The remaining 256bits I just want to discard.

I can access a specific frame and put the frame into a bitmap so that I can process the bitmap.
I am very new to SQL and do not understand as much about the language as I had hoped I would after a couple months of looking at it. I am creating a procedure database for work where we store word documents of procedures in a folder and use that to populate our database. I've been getting connection errors because I didn't realize I was trying to use the server.CreateObject command with an Apache DB and then using the connection string with an SQL Server DB. I am using SQL Server 2008 and I just ahd no idea why it wasn't connecting because I had been googling most errors.

I'm developing vb.net application with mysql as database. The database is on other machine in the network. In one function connection opens and executes query successfully. The same function makes call to other function.This second function tries ot do same thing. But this time while opening connection it gives error-"Access denied for user 'root1'@'AZAR' (using password: NO)". Here 'AZAR' is the name of my machine. The first function uses public variable declared in module for connection, whereas second function uses local variable for connection. I'm using PhpMyAdmin tool.

View 7 RepliesFinally starting some coding in VB.Net, I notice over the years, that we can say (in VB6)
Code: Dim MyForm_Stock as NEW frmStock
in the same session, being able to open, say 3 Stock Forms at the same time and maintain details independently of each of the other forms. Also am I able to maintain separate Database connections and the same table being opened and updated independently of each other by each separate form. What is actually taking place in terms of memory being used by each process? My ultimate goal is to be able to have ONE Module with all the possible data Connection and Recordset Opening and closing options, which I have failed miserably to do in my VB6 experience. Data access is an obvious module based set of subroutines. Others could be Date routines eg, Week Number of the year, Days Diff, Days to, etc. [Code]
I have made a PRN file using the "Print to file" option, and now I want to make a VB.net application that will print it directly to a TCP/IP printer which is not currently installed on the computer. Is it possible to achieve this by simply opening a connection to the printer's IP and sending all the bytes of the PRN file to it, or is it more complex than that?
