  • Convert.ToSingle() for float data Type

    - by Asim Sajjad
    I have used many of the Convert.To..... functions for conversion , but I didn't understand one thing that for every datatype they have provide a Convert.To function but not for float datatype, in order to convert to float you need to use Convert.ToSingle() , why is this so ?

  • Sites like itjobswatch.co.uk allowing to estimate $ value of particular IT skills and positions

    - by koppernickus
    I am using site itjobswatch to estimate $ value of particular IT skills and positions. I am using it also to observe salary trends for them. Sometimes I also use site salary.com where as a kind of hidden-feature one may list really impressing list of different IT positions and see salary statistics for them. What are the other similar sites, especially for markets other than UK and US?

  • Ajax and Brower Navigation for Back/Forward

    - by David Rodecker
    I am using a ASP.net form with custom onclick mouse events to modify data values. Upon clicking and updating the values, one div section of the form performs a postback. onclick="__doPostBack('ctl01$phCon1$gridReports','sel1')" This is working well, however when the browser BACK option is selected, the browser opens goes through the history of the DIV ajax/onclick actions prior to going back to the prior URL. I suspect that this may be due to the doPostBack being treated as a browsing operation. Is there a means to perform the necessary ASP.net code events to make the page work, but not have the action stored in the browser history?

  • sharing message object between web applications

    - by jezhilvalan
    I need to share java mail message objects between two web applications(A and B). WebApplication A obtains the message and write it to the outputStream for(int i=0;i<messagesArr.length;i++){ uid = pop3FolderObj.getUID(messagesArr[i]); //storing messages with uid names inorder to maintain uniqueness File f = new File("F:/PersistedMessagesFolder" + uid); FileOutputStream fos = new FileOutputStream(f); messagesArr[i].writeTo(fos); fos.flush(); fos.close(); } Is FileOutputStream the best output stream for persisting message objects? Is it possible to use ObjectOutputStream for message object persistence? WebApplication B reads the message object via InputStream FileInputStream fis = new FileInputStream("F:/MessagesPersistedFolder"+uid); MimeMessage mm = new MimeMessage(sessionObj,fis); What if the mail message object which is already written via WebApplication A is not a MimeMessage? How can I read non-mime messages using input stream? MimeMessage constructor mandates sessionObj as the first parameter? How can I obtain this sessionObj in WebApplicationB? Do I have to again establish store connection with the same emailid,emailpassword,popserver and port(already used in WebApplication A) with the email server inorder to obtain this session object? Even if obtained, will this session object remains the same as that of the session object which is priorly obtained in WebApplicationA? Since I am using uids to name Message objects (inorder to maintain uniqueness of file names) how can I share these uids between WebApplication A and WebApplication B? WebApplication B needs the uid inorder to access the specific file which is present in "F:/MessagesPersistedFolder" Please help me in resolving the aforeseen issues.

  • Do you use protective gear while programming?

    - by Can Berk Güder
    I've been suffering from a lot of elbow and forearm pain lately, and apparently it's caused by my arms and elbows constantly pressing against the desk. My doctor says I'm damaging the nerves on my elbow, and if I don't use elbow pads (or spend less time with the computer), it will get worse, and I will be risking permanent damage to the nerves. Since spending less time with the computer was not really an option, I purchased a pair of these: They didn't arrive yet, and I know they will probably make me look like a total idiot (my girlfriend has already started making jokes) when they do, but health comes first. Anyway, my question is: do you use any protective gear while programming? If yes, what do you use? Thanks,

  • keybd_event is not working right =(

    - by user302131
    I can't get this to work right. This should press left for 1 second then wait 10 seconds, then right 1 second, etc.: keybd_event(0x25, 0xCB, 0, 0); // press left cout << "Ldown\n"; // so i know it worked Sleep(1000); // hold it for 1sec keybd_event(0x25, 0xCB, KEYEVENTF_KEYUP, 0);// let go of the key cout << "Lup\n"; // so i know i let go Sleep(10000); // Sleep for 10secs keybd_event(0x27, 0xCD, 0, 0); // press right cout << "Rdown\n"; // so i know i pressed right Sleep(1000); // sleep 1sec keybd_event(0x27, 0xCD, KEYEVENTF_KEYUP, 0);// let go of the key cout << "Rdown\n"; // so i know i let go. This is in a loop but it wont do anything :( Unless I close the program before the key is let go, then it will just keep the key down until I press the key again. I know you can use only one key code if you want but I need to use both. So what am I missing?

  • Code Analysis - Treat as Error

    - by Brian Schmitt
    Looking to enable the "Enable code Analysis on Build" feature in Visual Studio. Obviously the Rules are a best practice, and I am working with an existing code base that currently fails many of the rules. I am looking for input as to which rules are the most egregious and should be treated as an Error.

  • Spoofing domains - using one domain to look at another without frame redirect

    - by hfidgen
    Hiya, In Plesk 9.2.2 does anyone know how the following can be achieved? I've got domain1.co.uk registered in plesk, but the domain has not been set up with any nameservers or A records, so it is unreachable from the web. However, I need to test it while we get the domain1.co.uk nameservers etc sorted over the next week or so. SO, i've got sparedomain.co.uk registered, with the nameservers and A records pointing to the server, and sure enough it displays the default plesk "theres no website here yet page" . bingo. Now, how can I set up sparedomain.co.uk on my plesk server, so it displays all the data held on the plesk account for domain1.co.uk? Frame forwarding doesnt work - because you get errors saying "domain1.co.uk cannot be found" in your browser - i need a server solution to spoof it all. Anyone got any ideas? Thanks!

  • Execute a remote command on a Mac from Windows

    - by ripper234
    What's the easiest way to execute a single command on a Mac from a remote Windows machine, via batch? I'd like minimal pre-configuration (like SSH credentials) to exist on either machines, as I need to apply this on several Win/Mac pairs. The macs all have a common user/password (in fact, they are on the same domain), and I want to automate this as painlessly as possible.

  • Excel - convert groupped data into PivotTable - is it possible?

    - by zmische
    I have report in Excel format (Excel 2007) from Accountant department - and it has Groupping by Rows. + Client 1 300$ (group Bills by Client) |-- BIll 1 100$ |-- Bill 2 200$ So in Excel It looks like this in plain rows format (If I ungroup those rows): 1 Client1 300$ 2 Bill1 100$ 3 Bill2 200$ 1,2,3 - row numbers. So I cant Pivot these data to get Client-by-Bill-SUm report, because rows with Client Name are not Connected (that is necessary for Pivoting info by Client, Bills) with Bills rows after UnGroupping.
