• WPF Issues with Control Layout

  - by Brett Powell

  I am making an application that connects to our billing software using its API, and I am running into a few issues getting the layout working properly. I want to make it so that when one of the expanders is minimized, the other window fills the gap, and when it is expanded again the other expander goes back to where it was. Right now when the arrow is clicked on one, there is just an empty gap. I used a DockPanel as the parent which I assumed would automatically do this, but it isn't working. Second question, is there a way to make these areas resizable? I don't want to try and get too frisky with allowing the user to undock the menus (don't even know if that is possible with just straight WPF) but it would be nice if they could change the width/height of them. Also, just a newbie question to C#, but what is the equivalent of a C++ header file? It looks like you just use .cs files, but I am not sure. I want to extract all of my functions that pull the data from the billing software and put them into a different file to clean up the code. Here is my XAML... <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Billing Management" Height="550" Width="754" xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="22" /> <RowDefinition /> </Grid.RowDefinitions> <Menu Height="22" Name="menu1" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Top" HorizontalContentAlignment="Left" IsEnabled="True" IsMainMenu="True"> <MenuItem Header="_File"> <MenuItem Header="_Open" /> <MenuItem Header="_Close" /> <Separator/> <MenuItem Header="_Exit" /> </MenuItem> </Menu> <TabControl Name="tabControl1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderThickness="1" Padding="0" TabStripPlacement="Bottom" UseLayoutRounding="False" FlowDirection="LeftToRight" Grid.Row="1"> <TabItem Header="Main" Name="tabItem1" Margin="0"> <DockPanel Name="dockPanel1" LastChildFill="True"> <ListBox Height="100" Name="listBox3" DockPanel.Dock="Top" /> <ListBox Name="listBox4" Width="200" DockPanel.Dock="Right" /> <DockPanel Height="Auto" Name="dockPanel2" Width="Auto" VerticalAlignment="Stretch" LastChildFill="True"> <shared:AnimatedExpander Header="Staff Online" Width="200" Name="expanderStaffOnline" IsExpanded="True" Height="194" BorderThickness="0" DockPanel.Dock="Top" VerticalContentAlignment="Stretch"> <ListBox Name="listboxStaffOnline" Width="Auto" Height="Auto" Margin="0" VerticalAlignment="Stretch" Loaded="listboxStaffOnline_Loaded" /> </shared:AnimatedExpander> <shared:AnimatedExpander Header="Test Menu 2" Height="Auto" Name="animatedExpander1" BorderThickness="1" Margin="0,0,0,0" IsExpanded="True" VerticalContentAlignment="Stretch"> <ListBox Height="Auto" HorizontalAlignment="Stretch" Name="listBox6" VerticalAlignment="Stretch" Margin="0" BorderThickness="1" /> </shared:AnimatedExpander> </DockPanel> <ListBox Height="100" Name="listboxAdminLogs" DockPanel.Dock="Bottom" Loaded="listboxAdminLogs_Loaded" /> <ListBox Name="listBox5" /> </DockPanel> </TabItem> <TabItem Header="Support" Name="tabItem2" Margin="0"> </TabItem> <TabItem Header="Clients" /> <TabItem Header="Billing" /> <TabItem Header="Orders" /> </TabControl> </Grid> </Window>

• Version Control: multiple version hell, file synchronization

  - by SigTerm

  Hello. I would like to know how you normally deal with this situation: I have a set of utility functions. Say..5..10 files. And technically they are static library, cross-platform - SConscript/SConstruct plus Visual Studio project (not solution). Those utility functions are used in multiple small projects (15+, number increases over time). Each project has a copy of a few files or of an entire library, not a link into one central place. Sometimes project uses one file, two files, some use everything. Normally, utility functions are included as a copy of every file and SConscript/SConstruct or Visual Studio Project (depending on the situation). Each project has a separate git repository. Sometimes one project is derived from other, sometimes it isn't. You work on every one of them, in random order. There are no other people (to make things simpler) The problem arises when while working on one project you modify those utility function files. Because each project has a copy of file, this introduces new version, which leads to the mess when you try later (week later, for example) to guess which version has a most complete functionality (i.e. you added a function to a.cpp in one project, and added another function to a.cpp in another project, which created a version fork) How would you handle this situation to avoid "version hell"? One way I can think of is using symbolic links/hard links, but it isn't perfect - if you delete one central storage, it will all go to hell. And hard links won't work on dual-boot system (although symbolic links will). It looks like what I need is something like advanced git repository, where code for the project is stored in one local repository, but is synchronized with multiple external repositories. But I'm not sure how to do it or if it is possible to do this with git. So, what do you think?

• Common Lisp condition system for transfer of control

  - by Ken

  I'll admit right up front that the following is a pretty terrible description of what I want to do. Apologies in advance. Please ask questions to help me explain. :-) I've written ETLs in other languages that consist of individual operations that look something like: // in class CountOperation IEnumerable<Row> Execute(IEnumerable<Row> rows) { var count = 0; foreach (var row in rows) { row["record number"] = count++; yield return row; } } Then you string a number of these operations together, and call The Dispatcher, which is responsible for calling Operations and pushing data between them. I'm trying to do something similar in Common Lisp, and I want to use the same basic structure, i.e., each operation is defined like a normal function that inputs a list and outputs a list, but lazily. I can define-condition a condition (have-value) to use for yield-like behavior, and I can run it in a single loop, and it works great. I'm defining the operations the same way, looping through the inputs: (defun count-records (rows) (loop for count from 0 for row in rows do (signal 'have-value :value `(:count ,count @,row)))) The trouble is if I want to string together several operations, and run them. My first attempt at writing a dispatcher for these looks something like: (let ((next-op ...)) ;; pick an op from the set of all ops (loop (handler-bind ((have-value (...))) ;; records output from operation (setq next-op ...) ;; pick a new next-op (call next-op))) But restarts have only dynamic extent: each operation will have the same restart names. The restart isn't a Lisp object I can store, to store the state of a function: it's something you call by name (symbol) inside the handler block, not a continuation you can store for later use. Is it possible to do something like I want here? Or am I better off just making each operation function explicitly look at its input queue, and explicitly place values on the output queue?

• Adding a search box to a windows forms web browser control that highlights text

  - by evan

  I have a windows forms (using c#) application. It displays a webpage and has a textbox/botton combination which can be used to search for text displayed to the user. Currently I search the inner text of all elements for the text in the textbox. And then I weed out the elements that are redundant (for example a word could be in a 'p' and 'b' element where the 'b' is a child element of 'p' so the element returned should be 'b'). Finally I run the ScrollIntoView(true) method on the found element. I'd now like to add a function that highlights the text (like if you search for a term in a real webbrowser). My first thought was to just inject html and or javascript code around the text but that seems like a messy solution. Any ideas on how I should do this? Thanks for your help!

• Agile version control?

  - by Paul Dixon

  I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?

• Version control for subtitle creation

  - by user3635

  We make subtitles for a TV series and I plan to use a VCS for it. The structure of project directory is like this: series/ episode1/nameofepisode1.str episode2/nameofepisode2.str episode3/nameofepisode3.str ... Question: When I finish subtitle of an episode, I want to assign release tag for this episode (episode1_v1). I wanted to use git for this, but in git tag is assigned only to the whole repository. What to do, so that I can view every episode progress separately? Maybe there are some more suitable VCS for this?

• Understanding Git's version control

  - by georgeliquor

  Is there a way to go through different commits on a file. Say I modified a file 5 times and I want to go back to change 2, after I already committed and pushed to a repository. In my understanding the only way is to keep many branches, have I got that right? If I'm right I'm gonna have hundreds of branches in a few days, so I'm probably not understanding it really. Could anyone clear that up please?

• Source control issue with deploying versions

  - by Bonefisher

  Hi all, we have this discussion about how to deploy to production revisions that are UAT closed without revisions with UAT not-closed status. We are using SVN and we figured out that we are not able to just take revisions without prior-revisions on the same file made. Let me explain it on this example: we have 3 revisions made on same file: r1: UAT closed (ready to deploy) r2: UAT not-closed (not ready) r3: UAT closed (ready to deploy) now I want to deploy only my changes for which the UAT is closed (e.g. r1 and r3). In SVN this is not possible because r3 contains also r2 changes.. How do you made this to work? Maybe branching? Or just take r1 and wait until r2 is UAT closed? thanks

• version control projects in eclipse

  - by Stan

  Say I have eclipse installed in office and home. Both eclipse are 3.5 but may have slightly difference, like plugins version. I'd like to commit the code to online repo when get off work and then checkout at home. What would be a possible solution? github? sourceforge? Are they free? Would those slightly difference in eclipse cause any problem? Since I might commit whole project folder which consist some configurations. Can the community explain a bit or suggest some keyword? I will look up more online. Thanks.

• (g)Vim with version control like Eclipse

  - by Somebody still uses you MS-DOS

  I was an Eclipse user, now I have to use Vim in my machine. I used to "compare" a file I edited with a CVS repository to do merges an commit the files, using a context menu and my mouse. Is this possible in Vim? Opening a vimdiff for a file before commiting, and commit it from vim itself? And how is that supposed to work? I'm supposing I would be editing a file. Then, I want to see the modifications. I run vimdiff in gvim, and a new window (or buffer) is opened. I run the modifications, save what is applicable (using vimdiff commands), and commit running another command. Is this all transparent in vim? Do I have to keep getting out of vim to my terminal, or can all be done inside it? Do I need to use some plugins, or just really simple functions inside my vimrc?

• get ubuntu terminal to send an escape sequence (control+shift+up)

  - by user62046

  This problem starts when I use emacs ( with -nw option). Let me first explain it. I tried to define hotkey (for emacs) as following (global-set-key [(control shift up)] 'other-window) but it doesn't work (no error, just doesn't work), neither does (global-set-key [(control shift down)] 'other-window) But (global-set-key [(control shift right)] 'other-window) and (global-set-key [(control shift left)] 'other-window) work! But because the last two key combinations are used by emacs (as default), I don't wanna change them for other functions. So how could I make control-shift-up and control-shift-down work? I have googled "(control shift up)", it seems that control-shift-up is used by other people, (but not very few results). In the Stack Overflow forum, Gille answered me as following: Ctrl+Shift+Up does send a signal to your computer, but your terminal emulator is apparently not transmitting any escape sequence for it. So your problem is in two parts. First you must get your terminal emulator to send an escape sequence, which depends on your terminal emulator, and is Super User material, or Unix.SE if you're using a unix system. Then you need to declare the escape sequence in Emacs, and my answer explains that part So I come here for this question: How do I get my terminal (I use ubuntu 10.04, and the built-in terminal) to send an escape sequence for Control+Shift+Up Control+Shift+down

• How can I disable Control-W in Windows XP?

  - by Tim Visher

  I'm an Emacs/Mac user trapped on Windows at work and I often type Control-W from muscle memory to delete a word and thus by mistake kill the entire window, including everything that I was working on. This a particularly egregious problem for Console2 as I run GNU Screen and am often doing many things at once. Is there any way to completely disable Control-W or remap it to something that is far harder to type? Thanks!

• HTTP Basic Auth Protected Services using Web Service Data Control

  - by vishal.s.jain(at)oracle.com

  With Oracle JDeveloper 11g (11.1.1.4.0) one can now create Web Service Data Control for services which are protected with HTTP Basic Authentication.So when you provide such a service to the Data Control Wizard, a dialog pops up prompting you to entry the authentication details:After you give the details, you can proceed with the creation of Data Control.Once the Data Control is created, you can use the WSDC Tester to quickly test the service.In this case, since the service is protected, we need to first edit the connection to provide username details:Enter the authentication details against username and password. Once done, select DataControl.dcx and using the context menu, select 'Run'. This will bring up the Tester.On the Tester, select the Service Node and using context menu pick 'Operations'. This will bring up the methods which you can test:Now you can pick a method, provide the input parameters and hit execute to see the results.

• ASP.NET 4.0- Menu control enhancement.

  - by Jalpesh P. Vadgama

  Till asp.net 3.5 asp.net menu control was rendered through table. And we all know that it is very hard to have CSS applied to table. For a professional look of our website a CSS is must required thing. But in asp.net 4.0 Menu control is table less it will loaded with UL and LI tags which is easier to manage through CSS. Another problem with table is it will create a large html which will increase your asp.net page KB and decrease your performance. While with UL and LI Tags its very easy very short. So You page KB Size will also be down. Let’s take a simple example. Let’s Create a menu control in asp.net with four menu item like following. <asp:Menu ID="myCustomMenu" runat="server" > <Items> <asp:MenuItem Text="Menu1" Value="Menu1"></asp:MenuItem> <asp:MenuItem Text="Menu2" Value="Menu2"></asp:MenuItem> <asp:MenuItem Text="Menu3" Value="Menu3"></asp:MenuItem> <asp:MenuItem Text="Menu4" Value="Menu4"></asp:MenuItem> </Items></asp:Menu> It will render menu in browser like following. Now If we render this menu control with tables then HTML as you can see via view page source like following.   Now If in asp.net 4.0 It will be loaded with UL and LI tags and if you now see page source then it will look like following. Which will have must lesser HTML then it was earlier like following. So isn’t that great performance enhancement?.. It’s very cool. If you still like old way doing with tables then in asp.net 4.0 there is property called ‘RenderingMode’ is given. So you can set RenderingMode=Table then it will load menu control with table otherwise it will load menu control with UL and LI Tags. That’s it..Stay tuned for more..Happy programming..

• Simple Preferred time control using silverlight 3.

  - by mohanbrij

  Here I am going to show you a simple preferred time control, where you can select the day of the week and the time of the day. This can be used in lots of place where you may need to display the users preferred times. Sample screenshot is attached below. This control is developed using Silverlight 3 and VS2008, I am also attaching the source code with this post. This is a very basic example. You can download and customize if further for your requirement if you want. I am trying to explain in few words how this control works and what are the different ways in which you can customize it further. File: PreferredTimeControl.xaml, in this file I have just hardcoded the controls and their positions which you can see in the screenshot above. In this example, to change the start day of the week and time, you will have to go and change the design in XAML file, its not controlled by your properties or implementation classes. You can also customize it to change the start day of the week, Language, Display format, styles, etc, etc. File: PreferredTimeControl.xaml.cs, In this control using the code below, first I am taking all the checkbox from my form and store it in the Global Variable, which I can use across my page. List<CheckBox> checkBoxList; #region Constructor public PreferredTimeControl() { InitializeComponent(); GetCheckboxes();//Keep all the checkbox in List in the Load itself } #endregion #region Helper Methods private List<CheckBox> GetCheckboxes() { //Get all the CheckBoxes in the Form checkBoxList = new List<CheckBox>(); foreach (UIElement element in LayoutRoot.Children) { if (element.GetType().ToString() == "System.Windows.Controls.CheckBox") { checkBoxList.Add(element as CheckBox); } } return checkBoxList; } Then I am exposing the two methods which you can use in the container form to get and set the values in this controls. /// <summary> /// Set the Availability on the Form, with the Provided Timings /// </summary> /// <param name="selectedTimings">Provided timings comes from the DB in the form 11,12,13....37 /// Where 11 refers to Monday Morning, 12 Tuesday Morning, etc /// Here 1, 2, 3 is for Morning, Afternoon and Evening respectively, and for weekdays /// 1,2,3,4,5,6,7 where 1 is for Monday, Tuesday, Wednesday, Thrusday, Friday, Saturday and Sunday respectively /// So if we want Monday Morning, we can can denote it as 11, similarly for Saturday Evening we can write 36, etc /// </param> public void SetAvailibility(string selectedTimings) { foreach (CheckBox chk in checkBoxList) { chk.IsChecked = false; } if (!String.IsNullOrEmpty(selectedTimings)) { string[] selectedString = selectedTimings.Split(','); foreach (string selected in selectedString) { foreach (CheckBox chk in checkBoxList) { if (chk.Tag.ToString() == selected) { chk.IsChecked = true; } } } } } /// <summary> /// Gets the Availibility from the selected checkboxes /// </summary> /// <returns>String in the format of 11,12,13...41,42...31,32...37</returns> public string GetAvailibility() { string selectedText = string.Empty; foreach (CheckBox chk in GetCheckboxes()) { if (chk.IsChecked == true) { selectedText = chk.Tag.ToString() + "," + selectedText; } } return selectedText; }   In my example I am using the matrix format for Day and Time, for example Monday=1, Tuesday=2, Wednesday=3, Thursday = 4, Friday = 5, Saturday = 6, Sunday=7. And Morning = 1, Afternoon =2, Evening = 3. So if I want to represent Morning-Monday I will have to represent it as 11, Afternoon-Tuesday as 22, Morning-Wednesday as 13, etc. And in the other way to set the values in the control I am passing the values in the control in the same format as preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); So this will set the checkbox value for Morning-Monday, Morning-Tuesday, Morning-Wednesday, Morning-Saturday, Afternoon of Tuesday and Afternoon of Wednesday. To implement this control, first I have to import this control in xmlns namespace as xmlns:controls="clr-namespace:PreferredTimeControlApp" and finally put in your page wherever you want, <Grid x:Name="LayoutRoot" Style="{StaticResource LayoutRootGridStyle}"> <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}"> <controls:PreferredTimeControl x:Name="preferredTimeControl"></controls:PreferredTimeControl> </Border> </Grid> And in the code behind you can just include this code: private void InitializeControl() { preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); } And you are ready to go. For more details you can refer to my code attached. I know there can be even simpler and better way to do this. Let me know if any other ideas. Sorry, Guys Still I have used Silverlight 3 and VS2008, as from the system I am uploading this is still not upgraded, but still you can use the same code with Silverlight 4 and VS2010 without any changes. May be just it will ask you to upgrade your project which will take care of rest. Download Source Code.   Thanks ~Brij
