Gathering Data From Several Different COM Ports And Reformat?
Apr 28, 2010
I have written a program that will gather data from several different COM ports and reformat the data before sending it to a web site. This program is intended to run 24/7, but only send the information at user specified intervals. I have the routines to gahter data, but I only need it to perform this task at the specified time (5 minutes to each hour). At startup the dialog minimizes to the system tray. I would like a balloon message notifiy anyone watching that the data is about to be sent, and allow them to add additional comments if they choose (by clicking on the balloon). The system tray icon has several context menu items that the user may need. Is this the proper use of a background thread? I would also like opinions on the best method for pausing execution until the specified time.

The code below randomly selects two players from "Preferences.txt" which has the names of all current players. (not necessarily all saved profiles) Now I need to find the best way to match 'Doer' and 'Receiver' with their profiles in "Players.txt" and get their profile attributes.

I want to gather some data from some tables of an Access Database, I've found some solutions online, but I haven't found ways to fill a datatable, or dataset, and get each single field properly. Is it easier for me to get whole tables then get just the info that i want, or should I make a lot of searches in the access DB getting just what I want each time? Any code snippets for it? The Access Database is in an ACCDB file, with no user or password. I'm currently using VB.NET, but it doesn't matter if you answer in C#. [URL]

I have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?

I am currently making an app in visual basic that I plan to make a chat server. I know that somehow I'm going to get the program to send and recieve data across ports on a certain ip address with variables such as maximum connections, etc.
The part I am mostly stuck on is firstly the code that you would need, or how to make a function to interact with ports across an ip.
Secondly, would it be a good idea to make a backround service to run for it to work on a host, and also how the other computers are going to find a host.

I am trying to set up a program that allows you to open multiple COM ports and then select which COM port you send data down. The computer i am using has 18 COM ports. Also on the first code it shows the ports are open they just wont receive anything.

My computer was running really slow so I decided to reformat my computer and reinstall Vista. I thought I had backed up everything I needed, but I COMPLETELY forgot to grab the Projects folder in my user folder, so this huge project I was working on is gone Does anyone know of any data recovery software that I could get for free (or even buy if it will definitely work) to get these files back? I can't afford professional data recovery.

finally my programme works. It will test the other programme, which is a Bid Tabulation programme allowing up to 10 Supplier Quotes each one having up to 500 line items; handling mixed currencies; many additional lines of specific information; etc.; using any combination of Suppliers and Line Items.However, I thought that I would let you know about some of the things I had to do to make it run.Obviously, the programme can bring up the Bid Tabulation programme very quickly, and then moves on to obtain the handle of the first form. But I had to insert a timing delay in order for the programme to report that it had found the handle; I also had to add the same delay all over the programme in order to see a valid handle number instead of "0".In addition to this I had to cycle through the ChildHandles, as you had indicated in order to get to the handle I needed. This raised another problem. I wanted to enter information in the same sequence as the tab order, but I found that the ChildHandle order was all over the place; generally back to front. In other words the tab order which went from top to bottom, and left to right, whereas the ChildHandle order was sometimes all over the place.
Is there a simple method of rearranging the ChildHandle order, as there is for arranging the tab order? I had to reformat several of my forms in order that entries would make sense. Imagine the table below is a form with 23 TextBoxes. The order that I need them to be filled is from top to bottom, and left to right, but the actual order of the TextBoxes is as below: [code] This message does not really require a resolution to a problem, unless there is a way of re-ordering the handles without having to completely reformat the form.

Are there any tools available for automatically formatting vb.net code - specifically for adding line breaks at a predefined line length? I'm working with a lot of code with long lines (thousands of lines), and manually reformatting it is quite time consuming. I've seen a number of tools for rearranging code into regions etc., but haven't found any that reformat with line breaks.

I'm trying to gather changing information (just text really) from a web page, or collection of web pages. For example, looking up the most recent weather predictions from weather.com.
After searching the Internet I came across some code (which I don't fully understand) that seems to get the job done but not very efficiently:
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("www.example.com")
Dim response As System.Net.HttpWebResponse = request.GetResponse
Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream)
Dim src As String = sr.ReadToEnd()

I have a task to resolve, it is regading extracting characters from a long string to the console, the extracted text shall be reformatted and saved into a CSV file. The string comes out of a database.
It looks something like: UNH+RAM6957+ORDERS:D:96A:UN:EGC103'BGM+38G::ZEW+REQEST6957+9'DTM+Z05:0:805'DTM+137:20100930154
The values are seperated by '.I can query the database and display the string on the console, but now I need to extract the Keyword 'ORDERS' for example, and lets say it's following 5 Characters. So the output should look like: ORDERS:D:96A then I need to extract the keyword 'BGM' and its following five characters so the output should look like: BGM+38G:After extracting all the keywords, the result should be comma seperated and look like:
ORDERS:D:96A,BGM+38G: it should be saved into a CSV file automatically.
I tried already:
'Lookup for containing KeyWords
Dim FoundPosition1 = p_EDI.Contains("ORDERS")
Console.WriteLine(FoundPosition1)
Which gives the starting position of the Keyword.I tried to trim the whole thing around the keyword "DTM". The EDI variable holds the entire string from the Database:
Dim FoundPosition2 = EDI
FoundPosition2 = Trim(Mid(EDI, InStr(EDI, "DTM")))
Console.WriteLine(FoundPosition2)

We need to put a firewall in between our servers and a couple of clients. To do this we need to limit the number DCOM ports available so that we know what ports to open on the firewall.The question I have is do we need to limit the number of ports on all the machines inside the firewall as well as outside. This would cause an issue as we have lots of machines which would need to be modified.If DCOM has the intelligence to negotiate on port 135 which port is available on both machines which need to communicate, we will only need to modify the 2 machines on the outside of the firewall.

I Need to be able to read an unknown number of serial ports (I plan to limit the number to 10). I'd like to use a datareceived handeler for all of them. This is what I came up with, that seems to work with my test ports. However I'm wondering if thiscould cause any problems if more data is received than I'm currently testing with. It is possible that one or two ports will be transmitting 16 records per second each. Here is the code I'm testing with:
