  • Populate an Object Model from a data dataTable(C#3.0)

    - by Newbie
    I have a situation I am getting data from some external sources and is populating into the datatable. The data looks like this DATE WEEK FACTOR 3/26/2010 1 RM_GLOBAL_EQUITY 3/26/2010 1 RM_GLOBAL_GROWTH 3/26/2010 2 RM_GLOBAL_VALUE 3/26/2010 2 RM_GLOBAL_SIZE 3/26/2010 2 RM_GLOBAL_MOMENTUM 3/26/2010 3 RM_GLOBAL_HIST_BETA I have a object model like this public class FactorReturn { public int WeekNo { get; set; } public DateTime WeekDate { get; set; } public Dictionary<string, decimal> FactorCollection { get; set; } } As can be seen that the Date field is always constant. And a single(means unique) week can have multiple FACTORS. i.e. For a date(3/26/2010), for Week No. 1, there are two FACTORS(RM_GLOBAL_EQUITY and RM_GLOBAL_GROWTH). Similarly, For a date(3/26/2010), for Week No. 2, there are three FACTORS(RM_GLOBAL_VALUE , RM_GLOBAL_SIZE and RM_GLOBAL_MOMENTUM ). Now we need to populate this data into our object model. The final output will be WeekDate: 3/26/2010 WeekNo : 1 FactorCollection : RM_GLOBAL_EQUITY FactorCollection : RM_GLOBAL_GROWTH WeekNo : 2 FactorCollection : RM_GLOBAL_VALUE FactorCollection : RM_GLOBAL_SIZE FactorCollection : RM_GLOBAL_MOMENTUM WeekNo : 3 FactorCollection : RM_GLOBAL_HIST_BETA That is, overall only 1 single collection, where the Factor type will vary depending on week numbers. I have tried but of useless. Nothing works. Could you please help me?. I feel it is very tough I am using C# 3.0 Thanks

  • Roughly cutting Fibre Cables

    - by Bryan
    I recently asked a question about which type of Fibre optic cable to use for my installation. We have now found a cable type and supplier and I'm about to order the cable (OM3, Tight Buffered, 12 Core), however I have a further question: We are shortly moving in to a new building (still being constructed) and we are about to get a window in which we will be able to run any cabling that we need. How should I roughly cut the fibre? Can I just use some heavy shears to cut through the cable? I'm aware that doing so will damage the ends, but will the damage be limited to the ends, or could the cracks/fractures continue up the length of the cable? p.s. I have already allowed for several metres of extra cable at each end, and I am going to get a specialist in to terminate the fibres.

  • What's the coolest machine you've ever worked on?

    - by mxg
    What's the most exotic, coolest, unique, or interesting machine you've worked on? Most of us work on machines with x86 architectures using some Windows or Linux variant. I'm sure there are those of you out there who are working on or have worked on machines with experimental architecures, or operating systems. Maybe you worked on a machine that has some sigificance in the history of computing. I'd be interested to hear about it. I'm sure others reading SO will as well. EDIT: I appreciate all of you who took some time to talk about their experiences with interesting or unusual machines. I enjoyed reading your answers. Although it wasn't my intent to get nostalgic, I see that theme amongst the responses.

  • Help with CSS - getting an element to fill 100% of the remaining vertical space

    - by Jack W-H
    Hi folks I'd consider myself a reasonable standard CSS/XHTML chap but I'm pretty baffled by this. The problem is available here: http://furnace.howcode.com - (note that the site is still in development, most stuff doesn't work, and it's likely to change fairly quickly as it is updated often). Basically I've got a fluid layout that needs to work in the same proportions on any resolution. Here's a screenshot of how the designer invisioned it (I apologise for my Paint-tool anotations): I want the tabs and the search box to STAY at the top of Col2, whilst there should be a scrollable area beneath it where the results are returned. I want NO vertical viewport scrolling, only within the 100%-height area thingy. My problem is this. If you take a look at http://furnace.howcode.com, you'll see that I've got a bit of a problem. I've made a placeholder black-background div which I will turn into the Tabs shortly. However I want the Col2 div to float BENEATH this and fill 100% of the remaining vertical height (i.e. go to the bottom of the screen, nomatter what the resolution is) and Col3 to be in the place where Col2 currently has been put (it normally is there automatically, when Col2 is in the right place!). I hope that makes sense. If you need to me to clarify please just ask. Cheers! Jack

  • How can I set a connection time out manually?

    - by Daniel
    I use connect(socketfd, (struct sockaddr*)&remoteAddr, sizeof(remoteAddr)) to connect my iPhone to a computer (over WIFI) and it works fine so far. However if the computer is out of reach, my iPhone tries to establish a connection for more than a min. Is there a posibility to set the time manually out to a new value, e.g. 15 sec?

  • WPF: KeyboardNavigationMode.Contained doesn't work to suppress focus wrap

    - by codymanix
    I want to navigate in my window with the arrow key. It works so far but if I reach the end of my window, focus wraps to the first main menu item. But I want that focus stops at the last control in my window. private void Window_PreviewKeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Down) { elem.MoveFocus(FocusNavigationDirection.Next); } } "elem" is indirect child control of "stackPanel". MoveFocus always returns true and I already tried: KeyboardNavigation.SetTabNavigation(stackPanel, KeyboardNavigationMode.Contained); KeyboardNavigation.SetDirectionalNavigation(stackPanel,KeyboardNavigationMode.Contained); KeyboardNavigation.SetControlTabNavigation(stackPanel, KeyboardNavigationMode.Contained); Nothing helped.

  • Does there exists a method to render an object using DebuggerDisplayAttribute

    - by Joe
    I have a number of classes that are decorated with DebuggerDisplayAttribute. I want to be able to add trace statements to Unit Tests that will display instances of these classes. Does there exist a method in the .NET Framework that will display an object formatted using DebuggerDisplayAttribute (or fall back to using .ToString() if no DebuggerDisplayAttribute is defined)?

  • Decimal data Type Display scale part as zero

    - by Wael Dalloul
    I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

  • c++ variable declaration

    - by swan
    Hello, Im wondering if this code: int main(){ int p; for(int i = 0; i < 10; i++){ p = ...; } return 0 } is exactly the same as that one int main(){ for(int i = 0; i < 10; i++){ int p = ...; } return 0 } in term of efficiency ? I mean, the p variable will be recreated 10 times in the second example ?

  • content management system

    - by Farax
    I am building a website for a client who needs a content management system to go with it. The client requires features such as content staging, approving process before publishing a page, provision for templates (changing which changes the lay out for the whole website), entry and expiry dates for pages and content search. I am planning to use an existing opensource CMS for the work but I am confused as to which one should it be. I need help in deciding whether this approach is good or should i develop my own CMS? and if I do use an opensource one, which one is extensible and customisable enough using .NET?

  • Setting Up virtualenv with python2.6

    - by Zach
    I'm setting up a virtualenv, but it seems to be using python2.5 by default. I'm using this command virtualenv newenv --no-site-packages -p python because the python found on my path is python2.6. I believe this to be true because when I type python and go into the shell, it tells me it's 2.6. When I create the virtualenv with the above command and launch the shell, it tells me I'm in 2.5. Anyone else have this issue?

  • Help choosing authentication method

    - by Dima
    I need to choose an authentication method for an application installed and integrated in customers environment. There are two types of environments - windows and linux/unix. Application is user based, no web stuff, pure Java. The requirement is to authenticate users which will use my application against customer provided user base. Meaning, customer installs my app, but uses his own users to grant or deny access to my app. Typical, right? I have three options to consider and I need to pick up the one which would be a) the most flexible to cover most common modern environments and b) would take least effort while stay robust and standard. Option (1) - Authenticate locally managing user credentials in some local storage, e.g. file. Customer would then add his users to my application and it will then check the passwords. Simple, clumsy but would work. Customers would have to punch every user they want to grant access to my app using some UI we will have to provide. Lots of work for me, headache to the customer. Option (2) - Use LDAP authentication. Customers would tell my app where to look for users and I will walk their directory resolving names into user names and trying to bind with found password. This is better approach IMO, but more fragile because I will have to walk an unknown directory structure and who knows if this will be permitted everywhere. Would be harder to test since there are many LDAP implementation out there, last thing I want is drowning in this voodoo. Option(3) - Use plain Kerberos authentication. Customers would tell my app what realm (domain) and which KDC (key distribution center) to use. In ideal world these two parameters would be all I need to set while customers could use their own administration tools to configure domain and kdc. My application would simply delegate user credentials to this third party (using JAAS or Spring security) and consider success when third party is happy with them. I personally prefer #3, but not sure what surprises I might face. Would this cover windows and *nix systems entirely? Is there another option to consider?
