I am trying to send data to a MS Access mdb. I have looked up tons of different things but I still cannot find what I need. I am not sure of what the correct name of the operation that I am looking for is? I already have the table saved. I just want to fill one cell in the table for now. The table is not in the same folder as my program. Or would it be better to have it in the same folder, if so how do I access the data as an mdb file?

View 1 RepliesI'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

In order to re-sort the data received in USB easier, I send the data array received in USB (declared as Byte) to a temporary array (declared as SByte) to re-sort. I declared the temporary array as SByte just for easy sorting. After I compiled, an error message came up "make sure not divided by zero". I tried to use convert.SByte but still didn't help. Is it not allowed to send data to an array with different data type declaration?

send data bytes (file data)
send end of file (0x03)
how to send the STX and ETX before and after the file data respectively. The PLC should receive them as 02 and 03 i.e. in their Hex values. If there is any ready function like vbCrLf for STX and ETX

I've been playing around with the TCP client/server sample code I found on [URL] but I can't seem to get it to function correctly. The problem I am having is that if I try to send data from the client a second time I get nothing back, not even an error that it couldn't send data. Every time I run the project it works the first time but that's it. When I was running the code line by line it seems to get to 'networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))' and then it jumps over the rest of the routine.

I have to send a sequence of video frames over UDP as fast and real-time as possible and while I got the basics working, I am running into all sorts of difficulties. Some of my goals:Data will normally be sent over dial-up (hence UDP instead of TCP), but also needs to support fast Ethernet.It's OK to occasionally drop frames (hence UDP instead of TCP).Need low latency. The frame the remote receives should be one that was recently sent (no more than a few frames waiting in buffers).I need to be able to detect the effective bandwidth so that I can compress the frames more or less to keep frame rate up.I break up frame data into one or more datagrams of about 500 bytes and each has a sequence number and other info. The receiver reassembles the entire frame and detects if any datagrams are missing.If the receiver detects more than a certain percentage of dropped frames (e.g. 50% over the last 10 frames), I send a TCP message to the sender to slow down by 50%. Sender than slowly increases speed by 5% each subsequent frame.Using System.Net.Sockets.UdpClient to send and receive the data.I have a separate TCP channel used for control messages back to sender.My main difficulty right now is detecting the effective bandwidth and dealing with latency, especially over dial-up (max ~4,000 bytes/sec). For example, if I try to send 100,000 bytes/second using TcpClient.Send() they ALL seem to arrive (no dropped datagrams) but with large latency by the time last datagram arrives. I think the TcpClient.Send() function is blocking until the buffer is able to send which messes up my current algorithm.
Can anybody point me to any sources of information for how to:Detect actual bandwidth over UDP.A better algorithm for dynamically adjusting bandwidth to suit the available pipe.Send data smoothly at the desired bandwidth.A way to detect and keep latency down to a minimum.I have been spinning my wheels over the last week and every time I solve one problem it seems another rears up is head.
