  • Writing datatable to database file, one record at a time

    - by Kevin
    I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time.

NA List the top three school ? one National two Devs three PS And a button for click event. The button click event will open MS word and paste the page contents in word. The word page contains the table property of html design page. It occurs only in Word 2003. But in word 2007 the word document contains the text with out table property. How can I remove this table property in word 2003. I am not able to add the snapshots. Else i will make you clear. I am designing the web page by aspx. I am exporting the web page content by the following code. protected void Button1_Click(object sender, EventArgs e) { Response.ContentEncoding = System.Text.Encoding.UTF7; System.Text.StringBuilder SB = new System.Text.StringBuilder(); System.IO.StringWriter SW = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter htmlTW = new System.Web.UI.HtmlTextWriter(SW); tbl.RenderControl(htmlTW); string strBody = "<html>" + "<body>" + "<div><b>" + htmlTW.InnerWriter.ToString() + "</b></div>" + "</body>" + "</html>"; Response.AppendHeader("Content-Type", "application/msword"); Response.AppendHeader("Content-disposition", "attachment; filename=" + fileName); Response.ContentEncoding = System.Text.Encoding.UTF7; string fileName1 = "C://Temp/Excel" + DateTime.Now.Millisecond.ToString(); BinaryWriter writer = new BinaryWriter(File.Open(fileName1, FileMode.Create)); writer.Write(strBody); writer.Close(); FileStream fs = new FileStream(fileName1, FileMode.Open, FileAccess.Read); byte[] renderedBytes; // Create a byte array of file stream length renderedBytes = new byte[fs.Length]; //Read block of bytes from stream into the byte array fs.Read(renderedBytes, 0, System.Convert.ToInt32(fs.Length)); //Close the File Stream fs.Close(); FileInfo TheFile = new FileInfo(fileName1); if (TheFile.Exists) { File.Delete(fileName1); } Response.BinaryWrite(renderedBytes); Response.Flush(); Response.End(); }

  • wcf trying to set up tracing to debug, not writing to log file

    - by joey j
    here's my web.config, running a WCF service in an application on IIS7, but nothing is being written to the specified file. permission on the file has been granted for everyone. </listeners> I can add a service reference just fine. I then try to call the service from a windows app and, after a few minutes, get an error on the machine running the windows app "Client is unable to finish the security negotiation within the configured timeout (00:00:00). The current negotiation leg is 1 (00:00:00)." but absolutely nothing is written to the trace log file specified in config. Is there something else I need to do to enable tracing? thanks for your help EDIT: "sources" section now matches the section recommended here: http://msdn.microsoft.com/en-us/library/aa702726.aspx I've added the "diagnostics and the event viewer shows: "Message Logging has been turned on. Sensitive information may be logged in the clear, even if it was encrypted on the wire: for example, message bodies. Process Name: w3wp Process ID: 1784 " but the log file is still empty

  • Writing a simple incrementing counter in rails

    - by Trip
    For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  • Writing white space to CSV fields in Python?

    - by matt
    When I try to write a field that includes whitespace in it, it gets split into multiple fields on the space. What's causing this? It's driving me insane. Thanks data = open("file.csv", "wb") w = csv.writer(data) w.writerow(['word1', 'word2']) w.writerow(['word 1', 'word2']) data.close() I'll get 2 fields(word1,word2) for first example and 3(word,1,word2) for the second.

  • Writing user stories for internal technical tasks

    I am attempting to manage my projects a little better so I am looking at attempting to apply some of (eventually all) the features of scrum. Looking at user stories specifically the high level format seems to be: As a User I can Feature Description or Artifact is Doing Something How would I write "Upgrade the Database"? Is it simply Upgrade the Database? I think I am being thrown off as there is no specific actor/customer and that the customer is the IT department.

  • Using htaccess rewrite to make a subdirectory be its own root for root relative path requests

    - by Scott
    Can I use htaccess to capture requests from a certain subdirectory and make that directory use itself as the root directory for any root relative path requests? For example if I have... http://www.example.com/subFIXED/subANY/restofpath ...where subFIXED is always the same directory, subANY is any immediate subdirectory of subFIXED, and I want a redirection of all href/src requests from any file under subANY to use subANY as the 'root' (sort of like a subdomain), in effect having root level requests use this as the root directory level: http://www.example.com/subFIXED/subANY/ Instead of this: http://www.example.com/ I'm assuming I can put an htaccess file in subFIXED to handle all calls coming from anything under any subANY, but not being very familiar with htaccess rewriting, variables, etc., I can't figure out how to capture which subANY directory is making the root level request and then use that capture to make a rewrite to consider that directory the root level of any root relative path requests from it. Thanks for your help

  • OutputStream with ByteArrayOutputStream not writing

    - by Yonatan
    Hey again Internet ! So i'm trying to write out an object to a ByteArray, but for some reason it's not writting anything, which i see by the fact that the return value is 0, and that by the fact that reading it results in an exception. BAoutput = new ByteArrayOutputStream(); Oout = new ObjectOutputStream(BAoutput); Oout.writeObject(receiver); where receiver is an object i get through a parameter. and the exceptions are always the same: at java.io.ObjectInputStream$BlockDataInputStream.peekByte(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) Any ideas?

  • ASP.NET Writing to the Bin directory, access denied when anonymous user

    - by LeeW
    Hi all I have a program that creates a small file in the Bin directory for the purpose of tracking a license (that's the intention), all works fine when debugging but I've just realized that when I run it on a IIS server under the anonymous user account (IUSR) the file isn't created as IUSR only has read permission (I know this is correct but drat!). Can I write to another location under IUSR account or can I run my code under 'Local Service' account? Thanks

    I'm trying to write from a loop to a data frame in R, for example a loop like this for (i in 1:20) { print(c(i+i,i*i,i/1))} and to write each line of 3 values to a data frame with three columns, so that each iteration takes on a new row. I've tried using matrix, with ncol=3 and filled by rows, but only get the last item from the loop. Thanks.

  • Detecting own posts on Facebook from a Chrome extension perspective

    - by Bane
    I want to create a Chrome extension that will automatically like every post I make on Facebook. My question is, how can I detect when I post something, and if that post if mine? Is there an event that occurs or something? (And just for the record, I know that these sorts of things are impossible when other apps post on my behalf, at least from an extension perspective. So I'm only concentrating on posts that I actually click the "post" button, or enter for, myself.)

  • StreamWriter stops writing when file is opened from web link

  • Word 2010 for writing invoices, starting with XML

    - by TomTom
    Hello, we are doing quite some invoice generation, and so far it is based on some pretty awful word automation that is now in for a review with Word 2010. I would love to move to a XML based format for storing / presenting invoices, only going to a word document in the last stage. This means I can use easily othermeans to present an invoice internally from the XML. We use Word as "last stage" because Word is a lot better than anything else ever discovered for formatting - our invoices have quite some text sometimes, in the invoice item table, and word is smartest with handling page breaks in the "correct" way. Now, here my question: is there any proper way by now to do this with XML easily? I remember Word having (had) in 2007 some XML field mapping mechanism, but it did not handle tables in the XML. Was anything changed? What would be the proposed approach for generating an .docx document (starting with a .dotx templace) for an invoice, if the relevant data is available in XML form?
