Transfer Real Time Data From Vb 2005 To Excel?

Nov 24, 2009

I am working on a project that is able to display real time data from sensors from micro-controller. I am able to do so by sending the data through the serial port and then use vb 2005 to show the data. However, I want to save those data from vb 2005 to excel. How am I able to do it ? I am able to use vb to insert data to excel step by step, cell by cell using the following codes.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim oExcel As Object
Dim oBook As Object
Dim oSheet As Object

[code]....

Lets say TextBox1.Text and TextBox2.Text is my real time data. How do I save it to the excel sheet displaying the data in cell A2, A3, A4 when the time goes by. Eg. If I want to save TextBox1.Text to excel it would be, the data in the 1st seconds in cell A2, data in the 2nd seconds in A3, 3rd seconds A4, 4th seconds in A5, A6 and so on...

Communications :: Real Time Data Collection From Socket And Storing In Excel

Jan 5, 2012

I m into automation development of FMCG products using Micro-controllers. I get real time data Barcode 2D from TCP/IP connection. My task is to compare the result do some Computation with them and Store the incoming Barcode and results into a Excel sheet in a folder. I m successful with the basic working. Am currently working at slow speed of 1 barcode(22 char info) per second from the TCP/IP data (barcode scanner). Now, comes the real issue. I need to process atleast 5 barcodes per sec ( <200ms per process). I m partially successful with 3 Barcode per second(300 ms per process). so, thats like 300ms per processing. I need to achieve less than 200ms for entire processing. I have used threads and timers. but I m unable to achieve. Seems like storing in Excel takes more than 250ms. Since i come from micro controllers background 1msec is a lotta time to process for me. I m not sure how much time does it take and trust me i find it difficult to guage the time here.

Office Automation :: Multi-threaded Real-time Data Handling In Excel With COM

Jun 22, 2010

I have an Excel based algo-trading app that needs to take in lots of real-time data, and make trading decisions based on the calculations driven by the data. It is not one of those "read-only" stock ticker kinda spreadsheets.I created a COM object with VB.NET that runs in its own thread space which collects data from a socket, and when the data is read it raises an Event with data attached. In Excel VBA, the event handler parses the data, puts them to the right places on the spreadsheet to feed calculations (so far it sounds like a stock ticker app), and then, based on the results of the various calculations it does something.The problem is that when the user starts to click around the spreadsheet while there is large amount of data coming, the event handler's cell updating breaks apart. If the app is left alone without user action, it stands well. My frustration comes from not understanding what happens to the main thread when a user clicks around. Either the event handler blocks the user action, or the user action blocks the event handler (under which case I will put in some queuing facility). But I just don't see how user action can break the code (like causing VBA to stop executing)

How To Send Real-time Data Over UDP

Sep 19, 2010

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.

Mirror Real Time Text?

Apr 6, 2012

I created a form with MS Access with some dropdown menus and some check boxes. The main reason is for when the user select a check box or an option from the dropdown menu a specific phrase will appear on a Note box I created on the bottom of the form. Where I am having the problem is because I added a Text Box in Access where the user can type something in it. What I need is when something is typed inside of the text box the content should be mirrored inside of the Note Box on the bottom of the form. I was able to create the functions using VB for the dropdown menus and the check boxes but for the Free Form Text Box I dont know how to mirror the real time texting.

Real-time Vehicle Animation In .NET?

Oct 14, 2009

I work for a company that produces accident reconstruction software. We have a vehicle dynamics program that realistically simulates the motion of a vehicle (position and rotation of car and steer angle of individual wheels, etc).

All the positions of the car are stored into an array called AMTN. The vehicle dynamics program can calculate positions at time steps finer than .005 secs (200 FPS).

I need to represent this data in real time, and so far I have not been able to accomplish this. I have tried doing this in Excel/VBA, VB6, and am currently trying to do it in VB.NET.

I have used a whole plethora of timers and counters as well as different methods of drawing lines on graphics linked to images linked to picture boxes, etc. My animation program writes/clears the screen correctly, but there is clearly some sort of lag in either the timer or writing method. I have scaled it down to 25 FPS and there is still a lag.

Here is an example of what I am trying to do with each tick of the timer:

Code:
Sub Timer1_Tick1(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
MyGraphic.Clear(Color.White)

[Code].....

With each tick of the timer, the graphic is cleared, lines representing each side of the car are drawn onto the graphic, and the picturebox is then assigned to the image, which is linked to the graphic. This is just like how your asteroids program works.

Do I need to change my method? Should I use sprites? Or would it be better for me to create images/bitmaps of the animation beforehand and simply flip through them with a timer?

I'm thinking that creating the images beforehand might work because I do not have to calculate the vehicle's position as it is predetermined by my AMTN matrix.

if there is a more efficient way of displaying my vehicle on the screen that would allow for greater FPS, etc.

I have no plans on using it just trying to learn variable structures and arrays and thought this type of program was a good start. Now I would like to take the text of a text box in runtime and use that to input a new check number into the variable structure. Just so I am not confusing anyone I will write the basic code

So what I would like to do is use a textox labeled check number to add check numbers into the checkrecord structure instead of having to add them into the code manually is this possible?

Generate A Real Time 2D Plot With Autoscaling?

Oct 27, 2010

I have finally made the switch VB.net and I am using VS2010 .NET 4.0 with WinForms. I want to generate a real time 2D plot with autoscaling and update the graphics/picturebox/form/<insert control here> from another thread so when I click a menu the device doesn't halt. The graphics are intensive in that a function is continually reading from hardware and drawing the data. I have been able to do this in VB6 (minus the multithreading) with GDI API and it ran great. Now in VB.NET GDI+ is used which is extremely slow. So my questions are as follows:

1) Should I go back to GDI commands or will this be outdated soon.

2) Should I use Direct2D, if so do I need to switch to WPF and are there any WinForm examples

3) Best approach to multithread this, if I double buffer can I have the GUI thread periodically read the buffer and display it. How can I tell the drawing thread to post an update and the UI thread displays it when it has the chance, similar to using InvalidateRect()

Real-time Application Communication Over A Network?

May 2, 2011

I am starting a new project in VB, a card game modelled to be similar to a real card game.

I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).

I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.

What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!

Using Fiddler2 To Txt Log Webpage Traffic In Real-time?

Me and a few other people are developing a piece of software that measures levels of distraction based on some user settings. The user will be able to designate certain programs, websites, etc. as "on task" and anything else will be considered "off task" by the program. The only road block we have run into is being able to grab the user's current web page in real time -- at any given second we need to be able to programatically determine what web page the user is viewing (in any browser) and determine whether it falls under "on task" or "off task". We would like to do this by creating a C# extension for Fiddler2 but are open to other suggestions as well (the software itself is programmed in VB.NET).

.NET And Displaying Real-time Received Serial Data On GUI?

I'm having a bit of an issue receiving a stream of serial data and displaying the data real-time in my GUI. I am fairly new to VB.Here's what I'm trying to achieve: I have an I2C device (bank of LED's) connected to my Arduino. Using the VB.NET (2010) GUI I request which LED I want on (via buttons) and the I2C device then sends a reply confirming which LED actually turned on (basic feedback). Ok, sounds great right? Here's where I get issues. Well when I try to read the serial data sent to VB and display the real-time stream on the GUI, a) I get a bit of a mess as an output (values are ok, just spewn across GUI) and b) when I select a new LED to turn on, the GUI data does not refresh to this change. The stream being sent from the Arduino is ok, I looked at the data in a serial monitor.
