  • Powerbuilder ressources

    - by afilatun
    I'm recently working in a company where we use PowerBuilder extensively. The only documentation or ressources we have access to is some basic course saying things like "Do A, then B and you'll get C". I was wondering if there is some better crash courses or tutorials for this language on the net or somewhere else which actually explain something instead of simply taking me by the hand.

  • Warning produced by f#: value has been copied to ensure the original is not mutated

    - by user1878761
    The first definition below produces the warning in the title when compiled with f# 3.0 and the warning level set to 5. The second definition compiles cleanly. I wondered if someone could please explain just what the compiler worries I might accidentally mutate, or how would splitting the expression with a let clause help avoid that. Many thanks. let ticks_with_warning () : int64 = System.DateTime.Now.Ticks let ticks_clean () : int64 = let t = System.DateTime.Now t.Ticks

  • declerative_authorization on User problem

    - by Webpain
    I am trying to block all default methods except create and update in my users controller using declerative_authorization. But at the time I add filter_resource_access or filter_access_to into my usersController i always get "Couldn't find User without an ID". Anyone care to explain why this could be happening? class UsersController :new end end def show @user = @current_user end def edit @user = @current_user end def update @user = @current_user # makes our views "cleaner" and more consistent if @user.update_attributes(params[:user]) flash[:notice] = "Account updated!" redirect_to account_url else render :action = :edit end end end

  • MS SQL Server stored procedure meaning

    - by den-javamaniac
    Hi. I'm developing a simple database architecture in VisualParadigm and lately ran over next code excerpt. IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'getType') AND type in (N'P', N'PC')) DROP PROCEDURE getType; Next goes my stored procedure: CREATE PROCEDURE getType @typeId int AS SELECT * FROM type t WHERE t.type_id = @typeId; Can anyone explain what does it mean? P.S.: It would be great, if you may also check for any syntax errors as I'm totally new to MSSQL and stored procedures.

  • Why not use GDI+ from ASP.NET

    - by roygbiv
    I've been told that using GDI+ from ASP.NET is dangerous and undefined. Is that because there is no guarantee of a Device Context? Can someone explain? What are some of the alternatives? Here is the source: http://msdn.microsoft.com/en-us/library/system.drawing.aspx

  • Object Events, how do are they implemented

    - by Malfist
    Events are really awesome, and I wouldn't know what I would do without them, but they're a mystery to me. I'm talking about events in a sense, a function(s) is called if a property, or value, a special event happens. I have only the vaguest idea how these actually work. I know it's an observer pattern, but I don't truly know how it works and/or how to implement it. Can someone explain that to me?

  • Updating shared files across computers

    - by murgatroid99
    I have a file server running Windows Server 2008 and a couple of laptops running Windows 7 on a network. There are a large number of files that all users will need access to. My plan is to have the files on both the server and the laptops because the users will need to access the files in places with no Internet access. I also want any changes made to the files on any of the laptops to propagate to the server and then propagate to the other laptops whenever they connect to the network. Should I do this with a scheduled batch script with a few xcopy commands or is there a better way to do it?

  • Best ways to move a server room and 80 desktops to a new building

    - by Marko
    Need to plan the best way to physically move a server room (12 IBM x3400 towers) and all associated networking equipment to a new building. Everything is going, comms (80 strong call centre operation), desktops(80-90) the whole lot and has to be done efficiently over a weekend. What I cant seem to find are the best ways to move equipment, i.e is it best to remove hard drives and pack them separetely, do I pack the chassis' with foam and/or surround them in bubble wrap? Are there specific products designed to move computer equipment and where would I find these. The internet has failed me so far, please help

  • Using git with cgit for decentralized/centralized development

    - by polemon
    I plan to use git for hosting my projects on my server. I've read about cgit, git-daemon, and I more or less decided to use those tools. But general use is still kind of confusing for me. What do I need to set up on the server, to push my files onto it. And when the files on the server are newer as the files on my computer, how do I merge them? Also, I use, say, two computers where I develop. How do I merge from one computer to the other? Also, when two people are working on the same project, how do they merge their local repos from one another? As you probably can tell by now, I come from SVN, but I've worked with Mercurial and now I'd like to test git.
