  • How do you store third party libraries in your source control?

    - by ajma
    How do you store third party libraries that you use in your project in your source control? When would you store binaries in your source control? When would you store the code in your source control? Would you ever store both? In what situations would you do this? (Btw, I'm using .NET but it doesn't really matter for this question)

  • Best Design Pattern for Coupling User Interface Components and Data Structures

    - by szahn
    I have a windows desktop application with a tree view. Due to lack of a sound data-binding solution for a tree view, I've implemented my own layer of abstraction on it to bind nodes to my own data structure. The requirements are as follows: Populate a tree view with nodes that resemble fields in a data structure. When a node is clicked, display the appropriate control to modify the value of that property in the instance of the data structure. The tree view is populated with instances of custom TreeNode classes that inherit from TreeNode. The responsibility of each custom TreeNode class is to (1) format the node text to represent the name and value of the associated field in my data structure, (2) return the control used to modify the property value, (3) get the value of the field in the control (3) set the field's value from the control. My custom TreeNode implementation has a property called "Control" which retrieves the proper custom control in the form of the base control. The control instance is stored in the custom node and instantiated upon first retrieval. So each, custom node has an associated custom control which extends a base abstract control class. Example TreeNode implementation: //The Tree Node Base Class public abstract class TreeViewNodeBase : TreeNode { public abstract CustomControlBase Control { get; } public TreeViewNodeBase(ExtractionField field) { UpdateControl(field); } public virtual void UpdateControl(ExtractionField field) { Control.UpdateControl(field); UpdateCaption(FormatValueForCaption()); } public virtual void SaveChanges(ExtractionField field) { Control.SaveChanges(field); UpdateCaption(FormatValueForCaption()); } public virtual string FormatValueForCaption() { return Control.FormatValueForCaption(); } public virtual void UpdateCaption(string newValue) { this.Text = Caption; this.LongText = newValue; } } //The tree node implementation class public class ExtractionTypeNode : TreeViewNodeBase { private CustomDropDownControl control; public override CustomControlBase Control { get { if (control == null) { control = new CustomDropDownControl(); control.label1.Text = Caption; control.comboBox1.Items.Clear(); control.comboBox1.Items.AddRange( Enum.GetNames( typeof(ExtractionField.ExtractionType))); } return control; } } public ExtractionTypeNode(ExtractionField field) : base(field) { } } //The custom control base class public abstract class CustomControlBase : UserControl { public abstract void UpdateControl(ExtractionField field); public abstract void SaveChanges(ExtractionField field); public abstract string FormatValueForCaption(); } //The custom control generic implementation (view) public partial class CustomDropDownControl : CustomControlBase { public CustomDropDownControl() { InitializeComponent(); } public override void UpdateControl(ExtractionField field) { //Nothing to do here } public override void SaveChanges(ExtractionField field) { //Nothing to do here } public override string FormatValueForCaption() { //Nothing to do here return string.Empty; } } //The custom control specific implementation public class FieldExtractionTypeControl : CustomDropDownControl { public override void UpdateControl(ExtractionField field) { comboBox1.SelectedIndex = comboBox1.FindStringExact(field.Extraction.ToString()); } public override void SaveChanges(ExtractionField field) { field.Extraction = (ExtractionField.ExtractionType) Enum.Parse(typeof(ExtractionField.ExtractionType), comboBox1.SelectedItem.ToString()); } public override string FormatValueForCaption() { return string.Empty; } The problem is that I have "generic" controls which inherit from CustomControlBase. These are just "views" with no logic. Then I have specific controls that inherit from the generic controls. I don't have any functions or business logic in the generic controls because the specific controls should govern how data is associated with the data structure. What is the best design pattern for this?

  • The Image ASP.Net web server control

    - by nikolaosk
    In this post I will try to show you how to use the ImageMap web server control. This is going to be a very easy example. We will write no code but I will use the control to create navigation hotspots. 1) Launch Visual Studio 2010/2005/2008. Express editions will be fine. 2) Create a new asp.net empty web site and call it “ NavigationHotspot ”. 3) Drag and drop in the default.aspx page a ImageMap web server control from the Toolbox. 4) Let me explain what I did. I have an image that contains two flags...(read more)

  • Version control and personal configuration file

    - by Erel Segal Halevi
    Our project uses a user-specific configuration file. This file is currently not in version control, since it is different for each user. The problem is, whenever a developer adds a new module that requires configuration, or changes the name of an existing modules, the other developers get errors because their private configuration files are not updated. To solve the problem, we thought of working with two configuration files: a default/global configuration file that will be in version control and will be updated regularly by each developer that adds a new module, and a private configuration file that will be kept out of version control and will contain only the user-specific changes. However, this still seems like an ad-hoc solution. Can you propose a better solution? What do the professionals do?

  • ThinkPad fan control via procfs

    My ThinkPad W500 used to crash sometimes under heavy load because the automatic control is not speeding up the fan far enough. But I was able to disengage the fan and let it run at full speed in Ubuntu 10.10. But this does not work in my new nice and shiny Ubuntu 11.10.

  • Error installing Package Control for Sublime Text 3 on Ubuntu 14.04

    - by user1837378
    This is the error. It comes up when I paste and enter the installation code (which I get from the Package Control website) and each time I open up Sublime Text. Package Control Your system's locale is set to a value that can not handle non-ASCII characters. Package Control can not properly work unless this is fixed. On Linux, please reference your distribution's docs for information on properly setting the LANG environmental variable. As a temporary work-around, you can launch Sublime Text from the terminal with: LANG=en_US.UTF-8 sublime_text I had the same problem with Ubuntu 13.04 so it's probably not version-dependent.

  • UbuntuGNOME 13.10 - Problem: Keyboard layout: Control L and Caps Lock swapped

    - by linuxubuntu
    I have a problem in UbuntuGNOME 13.10 which I didn't had in prior releases: I did a clean install and I don't know if it was already there or if I may have changed something, but my "Control L" and "Caps Lock" keys are swapped. How to swap them back? See also the attached image. http://i.imgur.com/PR1YB4T.jpg I swapped them back using but this is obviously not a proper fix $ cd ~ $ xmodmap -pke > .Xmodmap $ echo "remove Lock = Caps_Lock remove Control = Control_L keysym Control_L = Caps_Lock keysym Caps_Lock = Control_L add Lock = Caps_Lock add Control = Control_L" >> .Xmodmap $ xmodmap .Xmodmap but the "Keyboard Layout Chart" program shows the keys still swapped. What's the reason for this? How to fix?

  • Database Development and Source Control

    - by Enrique Lima
    I have been working with Database Development and the aspects that come with it, the pain and the joy of moving from Dev to QA and then on to Production.  Source Control has a place in Dev, and that is where the baselines should be established. Where am I going with this? I have been working with Redgate’s Source Control 3.0, and I am seeing some features that are great for the process of moving from Dev to … well something that allows for quite a level of control.  We are not only talking about scripting the structure of a database, but creating a baseline, working with migration scripts, and integrated with Redgate’s Schema Compare.  There is a detailed paper that will be posted here in the next day or so to provide step by step information of the process to define your baseline in Dev and then take it to the desired destination. In the meantime, check the Webinars Redgate has regarding this process and products.

  • Best way to patch (8) RJ45 ports from one room to another.

    - by zimmer62
    I have a 48 port patch panel in my basement, which I've wired almost all of them to various rooms around the house. Many are not actually being used at the moment, but pretty much all of them are wired to somewhere. As of recent, I've put in an HTPC in my media closet (different room), and I'm finding I need a lot more RJ45 plugs to this area. I have 4 drops here, and adding a switch will not solve my problems. I'm using the cabling for other things such as IR and Serial devices, not just Ethernet. What I'm hoping to do is add an 8 port panel in that media closet, and tie those into an 8 port panel on my rack next to the 48 port... What I don't want to do is pull 8 separate cables one by one from one area to the other unless someone has a technique that will allow me to do that quickly, and painlessly. Do they make cables with more conductors specifically for this purpose? Or patch panels that are designed for a special cable essentially just extending ports from one room to another?

  • Nested flowlayout panel not wrapping

    - by SnOrfus
    I've got a FlowLayoutPanel with properties: Dock = Fill (in a usercontrol) FlowDirection = TopDown WrapContents = false I do it this way so that each item added to the panel gets added to the bottom. The items that I add to this panel are usercontrols which themselves have FlowLayoutPanels on them, however they have the standard behaviour (LeftToRight, WrapContents = true). The problem that I'm having is that the interior usercontrol's FlowLayoutPanel isn't resizing to fill the outer control, but when I set autosizing to true on these controls, then the panel won't wrap its contents - which is a known problem apparently. If it helps visualize what I'm trying to do, it looks like this: ______________________________ | __________________________ | Outer box = exterior flowlayout | |Text____________________| | (TopDown, NoWrap) | | # # # # # # # # # # # #| | | | # # # # | | Interior boxes = usercontrols with text and a | |________________________| | flowlayoutpanel on them | __________________________ | (LeftToRight, Wrap) | |Text____________________| | | | # # # # # # # # # # # #| | # = pictures | | # # | | | |________________________| | |____________________________|

  • Accordion - Expand/Collapse - but first panel is opened and screws it up

    - by lorenzium
    Hey guys, I've got an accordion which has the first panel opened on default by throwing in: $("h4#open").trigger('click'); (which triggers the first panel to act as if the h4 link were clicked, and thus opened...) But this seems to screw up the only way I can think of expanding / collapsing all the panels. I have this code to expand / collapse: $("a.ex-col").click(function(){ $("div.accordion div").slideToggle("slow"); return false; }); When using this, all the panels toggle open and close except any panel that happens to be open (or closed) at the time. How can I keep the default div opened on load, while also expanding / collapsing with the rest of them? Thanks.

  • all individual panels are not shown inside root panel

    - by Suresh Kumar
    Respected sir/madam, I want to add multiple jpanels to jpanel.So i added a root panel to jscrollpane.and then added all individual jpanels to this root panel.I made jscrollpane's scrolling policy as needed.i.e HORIZONTAL_SCROLLBAR_AS_NEEDED,VERTICAL_SCROLLBAR_AS_NEEDED. But the problem is all individual panels are not shown inside root panel. Code: JScrollPane scPanel=new JScrollPane(); JPanel rootPanel=new JPanel(); rootPanel.setLayout(new FlowLayout()); JPanel indPanel = new JPanel(); rootPanel.add(indPanel); JPanel indPanel2 = new JPanel(); rootPanel.add(indPanel2); //.....like this added indPanals to rootPanel. scPanel.setViewPortView(rootPanel); //scPanel.setHorizontalScrollPolicy(HORIZONTAL_SCROLLBAR_AS_NEEDED); And one more thing is, as i scroll the scrollbar the panels are going out of jscrollpane area. I am not able to see all individual panels, Please suggest me.

    Is there a way to get a listing of control panel categories on Windows Vista and Windows 7 using the shell? Is there a way to determine which category an applet is assigned to using conical Names using the shell? such as Microsoft.Mouse is in which category? I have some code that works nicely to display control panel applet names obtained from the shell in a TListView in a Vista Classic ungrouped list. I'd like to try to group the applet names in the TListView similar to Control Panel Classic Grouped by Category in Vista. Bill

  • AJAX Panel not throwing exceptions

    - by Grant
    Hi, i have just noticed something strange in some asp.net markup. I have a standard form with a couple of textboxes and a submit button. When clicked the code behind will attempt to perform some logic and then return. If the input values are not valid it used to throw an exception. The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong. Does anyone know how to return this to the previous behavior whilst keeping the update panel?

  • Answers to “What source control system do you use?” (and some winners)

    - by jamiet
    About a month ago I posed a question here on my blog SQL Server devs–what source control system do you use, if any? (answer and maybe win free stuff) in which I asked SQL Server developers to answer the following questions: Are you putting your SQL Server code into a source control system? If so, what source control server software (e.g. TFS, Git, SVN, Mercurial, SourceSafe, Perforce) are you using? What source control client software are you using (e.g. TFS Team Explorer, Tortoise, Red Gate SQL Source Control, Red Gate SQL Connect, Git Bash, etc…)? Why did you make those particular software choices? Any interesting anecdotes to share in regard to your use of source control and SQL Server? I had some really great responses (I highly recommend going and reading them). I promised that the five best, most thought-provoking, responses (as determined by me) would win one of five pairs of licenses for Red Gate SQL Source Control and Red Gate SQL Connect; here are the five that I chose (note that if you responded but did not leave a means of getting in touch then you weren’t considered for one of the prizes – sorry): In general, I don't think the management overhead and licensing cost associated with TFS is worthwhile if all you're doing is using source control. To get value from TFS, at a minimum you need to be using team build, and possibly other stuff as well, such as the sharepoint integration. If that's all you need, then svn with Tortoise would be my first choice. If you want to add build automation later, you can do this with cruisecontrol (is it still called that?), JetBrains, etc. For a long time I thought that Redgate's claims about "bridging the SSMS-VS divide" were a load of hot air, since in my experience anyone who knew what they were doing was using Visual Studio, in particular SSDT and its predecessors. However, on a recent client I was putting in source control for the first time, and I discovered that the "divide" really does exist. That client has ended up using svn with Redgate SQL Source Control, with no build automation, but with scope to add it in the future. Gavin Campbell I think putting the DB under source control is a great idea.  I have issues with the earlier versions of SQL Source Control in that it provides little help in versioning the DB. I think the latest version merges SQL Compare and SQL Source Control together.  Which is how it should have been all along. Sure I have the DB scripts in SVN, but I can't automate DB builds and changes without more tools.  Frankly I'm surprised databases don't have some sort of versioning built into them. Nick Portelli Source control has been immensely useful and saved me from a lot of rework on more than one occasion.  I have learned that you have to be extremely careful checking in data.  Our system is internal only so during the system production run once a week, if there is a problem that I can fix easily(for example, a control table points to a file in the wrong environment), I'll do it directly in production so the run can continue as soon as possible since we have a specified time window.  We do full test runs to minimize this but it has come up once or twice.  We use Red-Gate source control to "push" from the test environment to the production environment.  There have been a couple of occasions where the test environment with the wrong setting was pushed back over the production environment because the change was made only in production.  Gotta keep an eye on that. Alan Dykes Goodness is it manual.  And can be extremely painful at times.  Not only are we running thin, we are constrained on the tools we can get ($$ must mean free).  Certainly no excuse, and a great opportunity to improve my skills by learning new things.  But...  Getting buy in a on a proven process or methodology is hard, takes time, and diverts us from development.  If SQL Source Control is easy to use and proven oh boy could you get some serious fans around here!  Seriously though, as the "accidental dba" of this shop any new ideas / easy to implement tools can make a world of difference in productivity and most importantly accuracy.  Manual = bad. :) John Hennesey (who left his email address) The one thing I would love to know more about is the unique challenges of working with databases as source code - you can store scripts, but are they written as deployment scripts with all the logic about how to apply them to an existing DB? Where is that baseline DB? Where's the data? How does a team share the data and the code? It's a real challenge. Merrill Aldrich Congratulations to the five of you. Red Gate will be in touch with you soon about your free licenses. Thank you to all those that responded. And again, go and check out all the responses – those above are only small proportion from what is a very interesting comment thread. @Jamiet

  • Book Review: Middleware Management with Oracle Enterprise Manager Grid Control 10g R5

    - by olaf.heimburger
    When you are familar with the Oracle Database and Middleware stack, chances are that you came across the Enterprise Manager. It comes in many versions for the database or the middleware and differs in its features. If meet someone who talks about Enterprise Manager, it might be possible that this person is talking about something completely different - Enterprise Manager Grid Control. Enterprise Manager Grid Control is the Oracle product for the data center that monitors all databases - and middleware components as well as operating systems. Since the database part is taken for granted, is needs some additional steps to get into the world of centralized middleware management. That's what this book is for - bringing you in the world of middleware management. The Authors This book is written by Debu Panda, former Product Management Director of the Oracle Fusion Middleware Management development team, and Arvind Maheshwari, Senior Software Development Manager of the Oracle Enterprise Manager development team. The Book Oracle Enterprise Manager conceptionally works for many different management areas. As a user you often think of managing databases with it. This is a wide area and deserves another book. The least known area is the middleware management and that's what the booked aimes for. The first 3 chapters cover the key features of Enterprise Manager Grid Control, Installing Enterprise Manager Grid Control, and Enterprise Manager Key Concepts and Subsystems. The foundation you need to understand the whole software and the following chapters. Read them in order and you are well prepared for the next 10 chapters on managing the various bits and pieces in your data center. The list of bits and pieces is always a surprise, no matter how often you open the book. You can manage Oracle WebLogic Server, Oracle Application Server, Oracle Forms and Reports Services, SOA Suite 10g, Oracle Service Bus 10g, Oracle Internet Directory, Oracle Virtual Directory, Oracle Access Manager, Oracle Identity Manager, Oracle Identity Federation, Oracle Coherence Cluster, Non-Oracle Middleware like Apache, Tomcat, JBoss, OBM WebSphere and much much more. The chapters for these components can be read in any order you like, you only need the foundation chapters and continue with the parts in your data center. Once you are done with them, don't forget to read the last chapter, Best Practices for Managing Middleware Components using Enterprise Manager. Read it, understand it, and implement it in your organization. This will save you valueable time and budget. Recommendation This book is mainly written for the Enterprise Manager newbies and saves you a lot of time while going through the standard product documentation. All chapters are considerable short and tell exactly what need to know to get started with. Nothing more and nothing less. That's the beauty of it and why I love it. Due to its limitation it will cover everything you'd like to know, but it gets you started and interested for more insights. But that is the job of the product documentation. The Details Title Middleware Management with Oracle Enterprise Manager Grid Control 10g R5 Authors Debu Panda and Arvind Maheshwari Paperback 310 pages ISBN 13 978-1-847198-34-1

  • How to center and scale Silverlight applications using ViewBox control

    - by Jacek Ciereszko
    There are many ways to make your application scalable in Web Browser window and align it in the center. Usually we use two Grid controls to align and panel control (like Canvas) to scale our apps. Not the best solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Grid HorizontalAlignment="Center" VerticalAlignment="Center">             <Canvas x:Name="scalePanel" VerticalAlignment="Top" HorizontalAlignment="Center">                 …             </Canvas>         </Grid>     </Grid> </UserControl>               The example above usually works but there are better ways. How? Use ViewBox. ViewBox control contains scale mechanisms with some stretching options. So ViewBox together with Grid control is all what we need to align and scale our applications. Good solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Viewbox>             ...         </Viewbox>     </Grid> </UserControl> How to find ViewBox control For those applications created in Silverlight 4, ViewBox is available in plug-in. For applications created in Silverlight 3 you can find it in Microsoft Silverlight Toolkit. Demo Let’s create a simple application that will contain: Button, TextBlock and red Rectangle. It will also have some Margin settings. This application won’t be in the center of window and it will not scale. <UserControl … >     <Grid x:Name="LayoutRoot">         <Grid Margin="100, 50, 100, 20">                 <StackPanel Orientation="Horizontal">                     <Button Width="100" Height="100" Content="test"/>                     <TextBlock Text="Button" Width="100" Height="100" />                     <Rectangle Width="100" Height="100" Fill="Red"/>                 </StackPanel>         </Grid> </Grid> </UserControl>   Run demo: RUN But If we use ViewBox control, we will got centered and always scaled application.    <Grid x:Name="LayoutRoot">         <Viewbox>             <Grid Margin="100, 50, 100, 20">                     <StackPanel Orientation="Horizontal">                         <Button Width="100" Height="100" Content="test"/>                         <TextBlock Text="bottom" Width="100" Height="100" />                         <Rectangle Width="100" Height="100" Fill="Red"/>                     </StackPanel>             </Grid>         </Viewbox>     </Grid> Link to application: RUN (try to resize application’s window) Link to source code: SilverlightCenterApplication.zip References ViewBox for Silverlight 3 http://silverlight.codeplex.com/    Polish version: http://jacekciereszko.pl/2010/05/jak-wysrodkowac-i-skalowac-aplikacje.html Jacek Ciereszko
