  • VS2010 "An item with the same key has already been added"

    - by fneep
    I recently installed Visual Studio 2010 and copied and converted an old VS2005 solution to VS2010 When I edit this solution, if I try to change a control's .image property, VS2010 creates a message box telling me that "An item with the same key has already been added" (screenshot below), and won't let me browse for an image. I can add images for any other solution, even others ported from VS2005, but not this one. Any idea what I'm doing wrong?

    I'm having trouble getting the setMap(null); function that everyone seems to be recommending to work. I believe it may be a problem with the way I've implemented the markers. If someone could take a look and let me know if you see something wrong I'd greatly appreciate it. LINK: http://www.dougglover.com/samples/UOITMap/v2/

  • Is there a WinForm control inspector application?

    - by Simon Gillbee
    I'm looking for something that provides interactive meta-data about a running .NET WinForms application. Basically, I'd like to be able to hover over a running WinForms application and have the inspector highlight the various controls and let me inspect properties such as size, position, parent, etc. I could have sworn I've seen this somewhere, but all my searching is turning up nada.

  • Monitor a COM port already in use.

    - by rross
    Is it possible to read from a COM port already in use on Windows XP? I would like to see the communication between some software and a device plugged into a serial device. I wrote a small program using C# to monitor the COM, but once it's in use by the other device it will not let you open it again. How can one monitor a COM port already in use? I'm open to 3rd party software. Thanks

  • Jquery-UI tabs : Double loading of the default tab

    - by Stephane
    I use jqueryui-tabs to display a tabbed UI. here is how my markup looks in a MasterPage: <div id="channel-tabs" class="ui-tabs"> <ul class="ui-tabs-nav"> <li><%=Html.ActionLink("Blogs", "Index", "Blog", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, new{ title="Blog Results" }) %></li> <li><%=Html.ActionLink("Forums", "Index", "Forums", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> <li><%=Html.ActionLink("Twitter", "Index", "Twitter", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> </ul> <div id="Blog_Results"> <asp:ContentPlaceHolder ID="ResultPlaceHolder" runat="server"> </asp:ContentPlaceHolder> </div> If the content is loaded via ajax, I return a partial view with the content of the tab. If the content is loaded directly, I load a page that include the content in the ContentPlaceHolder. somewhat like this : <asp:Content ID="Content2" ContentPlaceHolderID="BlogPlaceHolder" runat="server"> <%=Html.Partial("Partial",Model) %> </asp:Content> //same goes for the other tabs. With this in place, if I access the url "/Forums" It loads the forum content in the Blog tab first, trigger the ajax load of the Blog tab and replace the content with the blog content. I tried putting a different placeholder for each tab, but that didn't fix everything either, since when loading "/Forums" it will sure load the forum tab, but the Blog tab will show up first. Furthermore, when using separate placeholders, If I load the "/Blogs" url, It will first load the content statically in the Blog contentplaceholder and then trigger an ajax call to load it a second time and replace it. If I just link the tab to the hashtag, then when loading the forum tabs, I won't get the blog content... How would you achieve the expected behaviour? I feel like I might have a deeper probelm in the organization of my views. Is putting the tabs in the masterpage the way to go? Maybe I should just hijax the links manually and not rely on jquery-ui tabs to do the work for me. I cannot load all tabs by default and display them using the hash tags, I need an ajax loading because it is a search process that can be long. So to sum up : /Forum should load the forum tab, and let the other tabs be loaded with an ajax call when clicking on it. /Twitter should load the twitter tab and let the other tabs.... the same goes for /Blogs and any tabs I would add later. Any idea to have this working properly?

  • Fair Contract salary compared to permanent salary

    - by Ngu Soon Hui
    Let's say I have a position open, it can either be contract or permanent position. The question is what is the fair amount of money I should pay for the contract position, if I am willing to pay X per month for the permanent role? Contract pays are inevitably higher, because the contractors are not entitled for a lot of benefits, and not guaranteed of a job. I know the exact ratio of contract to permanent varies from person to person, but I need a rule of thumb here.
