• Escape characters during paste in vim

  - by Michael Anderson

  I copy stuff from output buffers into C++ code I'm working on in vim. Often this output gets stuck into strings. And it'd be nice to be able to escape all the control characters automatically rather than going back and hand editing the pasted fragment. As an example I might copy something like this: error in file "foo.dat" And need to put it into something like this std::string expected_error = "error in file \"foo.dat\"" I'm thinking it might be possible to apply a replace function to the body of the last paste using the start and end marks of the last paste, but I'm not sure how to make it fly.

• Wpf- Is there any way to disable some of the default hotkeys in a RichTextBox?

  - by Justin

  I have several keybindings in my text editing application that no longer work now that I have switched from using a regular textbox to using a richtextbox. This is because the wpf richtextbox has several default hokeys such as "Ctrl+1", "Ctrl+2", and "Ctrl+5". My keybindings are defined in a view that contains the view that the richtextbox is in. I can't move the keybindings to the richtextbox; Is there any fix for this problem? Other than using a third-party control or creating my own richtextbox from textboxbase.

• Event Tracking

  - by DRapp

  I want to understand event cycles. I have a form with a grid and textboxes. It has a grid, bound to DataTable, and textboxes bound to same table too. I'm trying to debug something and need to know how to identify ALL events fired in the form to see what may solve an issue for me. Anyhow, unless I explicitly subclass every class on my form, and override / attach to every event to my own event handlers, how can I get / listen to all events being fired during a certain action... Such as changing a "Selected" road in a DataGridView. It obviously updates its own "CurrentRow"... I need to know what / how to maybe FORCE a re-loading of SAME CurrentRow. Reason: during a form level "Edit Mode", and I change the content in another "Textbox" control, and reject changes, I need it to simulate the current "Record" is reloaded to go back to its original values.

• ASP.NET/JavaScript: How to surround an auto generated JavaScript block with try/catch statement

  - by Rami Shareef

  In the Script documents that asp.net automatically generates how can I surround the whole generated scripts with try/catch statement to avoid 'Microsoft JScript Compilation error' My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error. Thanks in advance

• NServiceBus is blocking when hosted in ASP.NET web application

  - by Dale Niemeyer

  Hello, I created a simple web application where a search form is filled out, submit button clicked, and a message is sent with the search parameters via nServiceBus. I also have a handler in the same project that picks up the message (from the same queue). For some reason, the web server process blocks until after the message is picked up, is there any reason for this? I set a breakpoint in the message handler and it breaks before the request finishes... locking the browser until I allow the code to continue. I would expect control to return to the browser regardless of when the handler gets fired... Thanks, D.Niemeyer

• Is there a best-practice approach for internationalization of an application?

  - by Lee Warner

  We need to have our apps be translated into other languages. This entails renaming the .text properties of our visible controls as well as other literals found within our apps to whatever language we need to translate into. Is this something that can easily be accomplished with .resx files? I was thinking of creating a master resx key/value list where the key would be the fully qualified name of the control/variable/constant etc. and then refactor our apps to look into this file to get their values based on the cultureinfo found at runtime? Is there a standard or simpler approach to this problem?

• Can .NET load and parse a properties file equivalent to Java Properties class?

  - by Tai Squared

  Is there an easy way in C# to read a properties file that has each property on a separate line followed by an equals sign and the value, such as the following: ServerName=prod-srv1 Port=8888 CustomProperty=Any value In Java, the Properties class handles this parsing easily: Properties myProperties=new Properties(); FileInputStream fis = new FileInputStream (new File("CustomProps.properties")); myProperties.load(fis); System.out.println(myProperties.getProperty("ServerName")); System.out.println(myProperties.getProperty("CustomProperty")); I can easily load the file in C# and parse each line, but is there a built in way to easily get a property without having to parse out the key name and equals sign myself? The C# information I have found seems to always favor XML, but this is an existing file that I don't control and I would prefer to keep it in the existing format as it will require more time to get another team to change it to XML than parsing the existing file.

• C#, WinForms: Which view type for periodically updated list?

  - by rdoubleui

  I'm having an application, that periodically polls a web service (about every 10 seconds). In my application logic I'm having a List<Message> holding the messages. All messages have an id, and might be received out of order. Therefore the class implements the Comparable Interface. What WinForm control would fit to be regurarly updated (with the items in order). I plan to hold the last 500 messages. Should I sort the list and then update the whole form? Or is data binding approriate (concerning performance)?

• DataTemplate defautl visibility for ContentControls

  - by bitbonk

  In my MVVM based WPF application I have a lot of different ViewModel types that dynamically loaded into ContentControls or ContentPresenters. Therefor I need to explictly set what DataTemplate is to be used in XAML: <ContentControl Content={Binding SomePropertyOfTypeViewModel} ContentTemplate={StaticResource someTemplate} /> Now my problem is that the content control is displaying the UI of someTemplate even if the ContentControl is bound to nothing (i.e ViewModel.SomePropertyOfTypeViewModel is null) Is there a quick and easy way to make all ContentControls display nothing if they are currently bound to nothing? When I use implicit DataTemplates everything works as expected. Unfortunately I can't use this mechanism here.

• Can I make controls defined in my markup public instead of protected

  - by RoboShop

  Say I have a web site with a master page and an aspx page. In my ASPX page, I am pointing to my masterpage with the MasterType tag. <%@ MasterType VirtualPath="~/mymasterpage.master" % Say, I've defined a label in the markup of my master page. If you look at the designer code, this label should be something like this. protected global::System.Web.UI.WebControls.Label label1; Now in my content page, I would like to reference this label. If I type in this "Master.label1", the complier will complain that the control is inaccessible due to the protection level" and rightly so, as label1 is automatically defined as "protected". My question is, if I define controls in my markup page, is it possible to set these controls as public instead of protected? I do not see an attribute for it. thanks in advance.

• Cloning just a particular directory with hg?

  - by leeand00

  I come from a Subversion background, but I am slowly migrating to Mercurial. When starting on many of my projects, I would setup a development environment that was configured to a particular starting point in developing an app/webapp/program (much like a Maven 2 archetype, but not necessarily Java/Maven). Later I would checkout this archetype/template project out of my svn repo by its particular path; and than export the working copy from version control by the repository; so that I could import the working copy back in to another repository without adding the changes that I made to the working copy to the base the template/archetype project. I've tried doing the same thing in Mercurial, and I've run into a wall since I can't check out, er..um..no, clone a specific path from the hg repository. If I want to achieve the same sort of functionality using Mecurial, what should I do? Use tagged branches? The archetypes/template projects are very different, but I'd like to keep them in the same repository.

• SharePoint Custom Application Page does not recognize tagPrefix defined in custom web.config

  - by Hasan Khan

  I have a custom application page integrated in Centeral Administration. My application pages are placed in a subfolder in Template\Admin folder. I placed my own web.config in my subfolder and added tagPrefixes in the control section. However when I open my application page ASP.NET throws the exception that the tag SharePoint:InputFormTextBox was not recognized. Moving the add tagprefix statements in root web.config solves the problem but thats not acceptable in my case and I can't define them in individual pages either. What am I doing wrong? Or it doesn't work this way? What can i do to achieve this?

• CSS :after pseudo element on INPUT field

  - by matra

  Hi, I am trying to use :after CSS pseudo element on INPUT field, but it does not work. If I use it with SPAN, it works OK. <style type="text/css"> .mystyle:after {content:url(smiley.gif);} .mystyle {color:red;} </style> This works (puts the smily after "buu!" and berfore "some more") <span class="mystyle">buuu!</span>a some more This does not work - it only color someValue in red, but there is no smiley. <input class="mystyle" type="text" value="someValue"> What am I doing wrong? should I use another pseudo selector. Note: I can not add SPAN sround my INPUT; because it is being generated by a third party control. Matraj

• Security exception with ASP.NET AJAX toolkit

  - by Rod

  I've got an ASP.NET WebForms app that I've written, which uses the ASP.NET AJAX Toolkit. I've put the MultiView control onto the web form, and it worked fine, when I had it under Vista. Well, I had to replace my machine (HD failed) and I went to Windows 7 Ultimate. I tried copying the ASP.NET app from the system (before it finally failed for good) and put it onto the Windows 7 machine. I can bring up the app fine, go to all pages, but the one with these controls on it. When I do I get the following error: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. What's going on? How do I fix it?

• Controlling the laziest common denominator

  - by bobobobo

  This is a programming-related question in that it has to do with combatting the laziest common denominator in a start-up like team. Some devs are driven. They wanna do stuff. They wanna build feature after feature. They wanna do it all. Others are.. lazy. And in every team there's someone who is the laziest. Some lazy people though have an influence on the others.. by their behavior and words, they actually make other people wanna do less. You can't always get rid of these people. But you need to control it. How?

• Is it possible to use IPC inside of a IE8 Browser Helper Object?

  - by Joel

  I need to communicate with a Service using IPC from inside of a Browser Helper Object (registered with IE8). Unfortunately, all of this communication is done through an Assembly API that I have no control over. Whenever this API starts up I get the following error: ExceptionSystem.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: The system cannot find the file specified. I realize that it is difficult to discern what the issue is without source. However I am curious if anyone knows of anything sort of permissions or DLL issues that would prevent IPC from working in this case.

• How do I hook up a custom tab bar build in IB to a UINavigationController Object instanced in XCODE?

  - by David Hsu

  What I did to create the custom NAV BAR: 1. Created an empty XIB and added a view with class UINavigationController. 2. Under the view I added the navigation bar and a left and right button onto the nav bar. 3. Control drag from "File Owner" to "View" Inside my class where I call the modal view navigation controller: SignupViewController *addController = [[SignupViewController alloc] initWithNibName:@"SignupViewController" bundle:nil]; // Create the navigation controller and present it modally. UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController]; navigationController.navigationBar = ///WHAT SHOULD GO HERE? [self presentModalViewController:navigationController animated:YES]; Thank in advance!

• How to segue modal without losing tab bar controller

  - by Arian

  Okay, so I want to be able to have a TabBar Controller with two Tabs (like the template in Xcode), but inside the Second tab, I want to have a button that takes the view to a Third View Controller. I want the Third View Controller to have a back button to the Second Tab, I don't want the Third View to retain the TabBar, but when I go back to the Second Tab I want the TabBar to return. So this is what I actually did, and it doesn't work. I put a button in 2nd view and 3rd view, and I control clicked and dragged to the respective views, and clicked modal. Everything works, except when I go back to the 2nd view I lose the tab bar. Pictures of what I am talking about: http://s13.postimage.org/78gqghflj/Screen_Shot_2012_07_09_at_2_03_41_PM.png http://s16.postimage.org/gdwus4w6t/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_50_PM.png http://s10.postimage.org/5uq3ste7d/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_57_PM.png http://s8.postimage.org/gpmsx959x/i_OS_Simulator_Screen_shot_Jul_9_2012_2_03_54_PM.png

• Access Elements inside a DataTemplate... How to for more than 1 DataTemplate?

  - by GaaTY

  I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State). I followed the example here: http://blogs.msdn.com/b/wpfsdk/archive/2007/04/16/how-do-i-programmatically-interact-with-template-generated-elements-part-ii.aspx about how to access the Elements inside the DataTemplates from Code behind. I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException. What could i be doing wrong?

• "Cannot convert to IComparer"

  - by Odrade

  I have the following IComparer defined for boxed RegistryItem objects: public class BoxedRegistryItemComparer : IComparer<object> { public int Compare(object left, object right) { RegistryItem leftReg = (RegistryItem)left; RegistryItem rightReg = (RegistryItem)right; return string.Compare(leftReg.Name, rightReg.Name); } } I want to use this to sort an ArrayList of boxed RegistryItems (It really should be a List<RegistryItem, but that's out of my control). ArrayList regItems = new ArrayList(); // fill up the list ... BoxedRegistryItemComparer comparer = new BoxedRegistryItemComparer(); ArrayList.sort(comparer); However, the last line gives the compiler error: "Cannot convert from BoxedRegistryItemComparer to System.Collections.IComparer". I would appreciate it if someone could point out my mistake.

• UITableViewCellStyleDefault label width

  - by Rob Bonner

  Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!
