  • Auto scrolling control (WinAPI)?

    - by user146780
    In C# (.Net) you can create a panel and set autoscroll to true. you can then add controls into it, including beyond it's size, then it will scroll. I was wondering if when using the real WinAPI in c++ (not .net) how one could acheive the same result. Must I keep track of the controls inside and move them all when I scroll or is there an easier way like in C#. Thanks

  • How to control utf-8 string paddings

    - by Kev
    I got three UTF-8 stings: hello, world hello, ?? hello, ?rld I only want the first 10 chars so that the bracket in one column: [hello, wor] [hello, ? ] [hello, ?r] In console: width('??')==width('worl') width('? ')==width('wor') #a white space behind '?' python's format() doesn't help when UTF-8 chars mixed in >>> for s in ['[{0:<{1}.{1}}]'.format(s, 10) for s in ['hello, world', 'hello, ??', 'hello, ?rld']]: ... print(s) ... [hello, wor] [hello, ?? ] [hello, ?rl] So, I wonder if there is a standard way to do the UTF-8 padding staff?

  • Can I control object creation using MEF?

    - by Akash
    I need to add some extension points to our existing code, and I've been looking at MEF as a possible solution. We have an IRandomNumberGenerator interface, with a default implementation (ConcreteRNG) that we would like to be swappable. This sounds like an ideal scenario for MEF, but I've been having problems with the way we instantiate the random number generators. Our current code looks like: public class Consumer { private List<IRandomNumberGenerator> generators; private List<double> seeds; public Consumer() { generators = new List<IRandomNumberGenerator>(); seeds = new List<double>(new[] {1.0, 2.0, 3.0}); foreach(var seed in seeds) { generators.Add(new ConcreteRNG(seed); } } } In other words, the consumer is responsible for instantiating the RNGs it needs, including providing the seed that each instance requires. What I'd like to do is to have the concrete RNG implementation discovered and instantiated by MEF (using the DirectoryCatalog). I'm not sure how to achieve this. I could expose a Generators property and mark it as an [Import], but how do I provide the required seeds? Is there some other approach I am missing?

  • Control is set to false, jQuery selector fails

    - by Damien Joe
    Hi I have some controls on an asp.net modal which I show manually via code behind. Now I am trying to attach a selector on one of the controls inside pageLoad(), problem being is that the modal container is initially set to visible=false. I tried checking for length but it still throws exception if ($('#<%= myControl.ClientId %>').length > 0) { $('#<%= myControl.ClientID %>').click(function() { // Do work }); } Compiler Error Message: CS0103: The name 'myControl' does not exist in the current context

  • Getting mediafire directlink without using WebBrowser .NET control ?

    - by NVA
    I'm looking for the way to get the direct link from mediafire. By default, when a user visits a download link, he will be presented with a download page where he has to wait for the download to be processed and then a link will appear. I googled and found a VB.NET 2008 solution to this using WebBrowser WB http://www.vbforums.com/showthread.php?t=556681 It works pretty well but I'm tired of pop-up windows and the loading speed. So, I wonder if there is a solution to this problem? (a non WB solution ^^) Any help is greatly appreciated.

Does anyone know why this is?

  • Object viewer control needed (like QuickWatch in VS)

    - by Wallstreet Programmer
    Anyone know of any controls that you can add to your application to allow the user to check out the content of an object? I'm thinking of something like QuickWatch in Visual Studio, just list all properties of an object and its values and allow the user to drill down. I started writing one using reflection but it turned out be a lot of work to handle different kind of collections. This functionality would be used for debugging purposes mostly and not by regular users. I prefer WPF but Winforms would work as well.

  • WPF databind in memory image to Image control

    - by Ready Cent
    I am using a DataGrid and trying to do the following Databinding <DataTemplate> <Grid> <Image> <Image.Source> <BitmapImage UriSource="{Binding Data.CustomImage}" CacheOption="OnLoad" /> </Image.Source> </Image> </Grid> </DataTemplate> CustomImage is of type BitmapImage. When I run I get the error: Initialization of 'System.Windows.Media.Imaging.BitmapImage' threw an exception. The thing is that these images are stored as resources in a different assembly so I can't just point to a location on disk
