  • Code a timer in a python GUI in TKinter

    - by Diego Castro
    I need to code a program with GUI in python (I'm thinking of using TKinter, 'cause it's easy, but I'm open to suggestions). My major problem is that I don't know how to code a timer (like a clock... like 00:00:00,00 hh:mm:ss,00 ) I need it to update it self (that's what I don't know how to do) Another question is how do I put a program in the system tray (I don't think it's called like that in Linux) for UBUNTU.

  • NSTimer timestamp timeinterval question

    - by okami
    I have the following code: [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(timerCount:) userInfo:nil repeats:YES]; -(void)timerCount:(NSTimer *)timer { NSTimeInterval dt = [timer timeInterval]; // do something } The NSTimeInterval I got will be 0.5, the time interval I've put on scheduledTimerWithInterval, this means the timerCount will be called each 0.5 seconds. But I now that there are some stuff as timeStamps, and I want to know if the NSTimer will call the timerCount method in PRECISELY 0.5 seconds each time.

  • Manifest or Theme/Style for a IWebBrowser2 control?

    - by Bob
    The IWebBrowser2 control has password edit boxes which are squares. This happened many years ago if you were on an XP machine, and you had a password edit field without a manifest file, you would get squares (no character found for the * they put in there with that font). My application has a manifest file. However I don't know how to give a manifest or set the theme or style of the control that is created. Any ideas? Thanks!

  • Problem in vertical navigation menu using css sprites

    - by ShiVik
    Hello all I am trying to create to a vertical navigation menu using CSS sprites. I want to put in it a hover effect where the menu option slides out a bit. a:link { background: url(images/nav.png); background-position: -100px 0px; width: 150px; } a:hover { background: url(images/nav.png); background-position: -100px 0px; width: 160px; } So I am using the same image, I am just increasing its size to create a pop out effect. But my problem is that right now the image's size is increasing to the right. I want to keep the image's base aligned and its head should pop out. Here's my complete css code: #navmenu { left: 100px; margin: 0; padding: 0; position: absolute; top: 150px; width: 150px; z-index: 99; } #navmenu ul { list-style-type: none; margin: 0px; padding: 0px; } #navmenu ul li { line-height: 1.5em; padding: 0px; } #navimenu ul li a { color: black; display: block; font-weight: bold; height: 26px; padding: 0px 15px 0px 0px; text-align: right; width: 150px; } #navmenu a:link, #navmenu a:visited { background: url(images/nav.png) no-repeat; background-position: -150px 0px; width: 150px; } #navmenu a:hover { background: url(images/nav.png) no-repeat; background-position: -150px 0px; width: 160px; } Don't know how much if I've put the problem correctly but can somebody help me out here? Thanks

  • How to create custom asp.net validator that works with UpdatePanel?

    - by Goran
    I think that subject summs it pretty well... I have created my custom validators that work great when I put them on page in design mode. However if I place them in a usercontrol, and then try to add this user control to the parent page via updatepanel, then my custom validators just won't trigger. They simply don't work. Does anyone have any clue on what I have to do here? .net 3.5

  • Duplicate content in ASP.NET MVC because of custom routes MapRoute(), are areas the rescue?

    - by artvolk
    I use custom routes for my URLs and my action become accessible via two URLs (not counting trailing slash and lower\upper case letters): one via my custom route /my-custom-route-url/ and one via default /controller/action. I see one possible solution -- put all controllers which use default routing (they are mostly backend) in one area, and place all others in separate area and use it without default route. May be there is a better way?

  • Problem with GetDefaultPrinter() over a VPN c++

    - by Ian Crowder
    I am writing an application that gets its dimensions from the paper ratio of the default printer of the local computer. This all works well unless the default printer is over a VPN. When this is the case, calling GetDefaultPrinter() takes too long. I need to find a way to put a time constraint on GetDefaultPrinter() and if it exceeds that constraint, break out of the function. Any possible solutions would be great. Thanks, Ian

  • Handling empty UITableView in UITableViewController

    - by Travis
    I have a UITableViewController that is populated with some data. If the data comes back empty, obviously the table is empty. What is the appropriate method to use to handle this case and put up something like a UILabel with "No Data Available". I have been using - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section but it's proven a bit cumbersome and I'm not longer confident it's the best place to do this.

  • Using embedded resources in Silverlight (4) - other cultures not being compiled

    - by Andrei Rinea
    I am having a bit of a hard time providing localized strings for the UI in a small Silverlight 4 application. Basically I've put a folder "Resources" and placed two resource files in it : Statuses.resx Statuses.ro.resx I do have an enum Statuses : public enum Statuses { None, Working } and a convertor : public class StatusToMessage : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (!Enum.IsDefined(typeof(Status), value)) { throw new ArgumentOutOfRangeException("value"); } var x = Statuses.None; return Statuses.ResourceManager.GetString(((Status)value).ToString(), Thread.CurrentThread.CurrentUICulture); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } in the view I have a textblock : <TextBlock Grid.Column="3" Text="{Binding Status, Converter={StaticResource StatusToMessage}}" /> Upon view rendering the converter is called but no matter what the Thread.CurrentThread.CurrentUICulture is set it always returns the default culture value. Upon further inspection I took apart the XAP resulted file, taken the resulted DLL file to Reflector and inspected the embedded resources. It only contains the default resource!! Going back to the two resource files I am now inspecting their properties : Build action : Embedded Resource Copy to output directory : Do not copy Custom tool : ResXFileCodeGenerator Custom tool namespace : [empty] Both resource (.resx) files have these settings. The .Designer.cs resulted files are as follows : Statuses.Designer.cs : //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace SilverlightApplication5.Resources { using System; /// <summary> /// A strongly-typed resource class, for looking up localized strings, etc. /// </summary> // This class was auto-generated by the StronglyTypedResourceBuilder // class via a tool like ResGen or Visual Studio. // To add or remove a member, edit your .ResX file then rerun ResGen // with the /str option, or rebuild your VS project. [global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Resources.Tools.StronglyTypedResourceBuilder", "4.0.0.0")] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] internal class Statuses { // ... yadda-yadda Statuses.ro.Designer.cs [empty] I've taken both files and put them in a console application and they behave as expected in it, not like in this silverlight application. What is wrong?

  • css newline issues (I think!)

    - by user328371
    Hi, I'm trying to create a breezebrowser template (used for generating image galleries locally, outputs HTML). I've taken the HTML from my wordpress template and managed to generate the following gallery http://uploads.peasyphotos.com/20100607t-candids/gallery/ but each image goes on a new line and i don't know why, i presume it's in the CSS. What should I be looking for in the CSS to try and stop this, or what can I put around my template code to disable the CSS for that part? Thanks
