  • Windowless OpenGL

    - by ext
    Hi, I would like to have a windowless OpenGL context (on both GNU/linux with Xorg and Windows). I'm not going to render anything but only call functions like glGetString, glCompileShader and similar. I've done some goggling but not come up with anything useful, except creating a hidden window; which seems like a hack to me. So does anyone have a better idea (for any platform)?

  • Has anyone had trouble with Intellisense in Visual Studio when using UltraVNC?

    - by mullala
    Hi, a colleague and I are trying pair programming for the first time. We both remote into a development machine; I'm using RemoteDesktop and my colleague is using UltraVNC. This works great except that he can't see the Intellisense dropdown in Visual Studio 2008. According to online posts, this may be something to do with DirectDraw, but I don't see much by way of a workaround. Has anyone else experienced this? Thanks, Andrew

  • Which style of return is "better" for a method that might return None?

    - by Daenyth
    I have a method that will either return an object or None if the lookup fails. Which style of the following is better? def get_foo(needle): haystack = object_dict() if needle not in haystack: return None return haystack[needle] or, def get_foo(needle): haystack = object_dict() try: return haystack[needle] except KeyError: # Needle not found return None I'm undecided as to which is more more desirable myself. Another choice would be return haystack[needle] if needle in haystack else None, but I'm not sure that's any better.

  • How to uncheck header checkbox in GridView when sorting and paging?

    - by OutOFTouch
    Hi, I followed this article and it works great except when paging or sorting the HeaderCheckBox is still checked. How and where should this be unchecked? I think it would be best to uncheck it in the control itself, but I am not having any luck even getting a reference to it using this code: protected override void OnSorted(EventArgs e) { base.OnSorted(e); if (AutoGenerateCheckBoxColumn) { CheckBox cb = (CheckBox) HeaderRow.FindControl(String.Format(HeaderCheckBoxId, ClientID)); if(cb != null) { cb.Checked = false; } } } Thanks

  • When would JavaScript == make more sense than ===?

    - by bryantsai
    As 359494 indicates they are basically identical except '===' also ensures type equality and hence '==' might perform type conversion. In Douglas Crockford's JavaScript: The Good Parts, it is advised to always avoid '=='. However, I'm wondering what the original thought of designing two set of equality operators was. Have you seen any situation that using '==' actually is more suitable than using '==='?

    - by Denis Sadowski
    Hi All, I have a crystal report which when generated has a last page that is blank except for the page footer (which indicates the current page, as well as the report title).

  • LINQ: How to skip one then take the rest of a sequence

    - by Marcel
    Hi All, i would like to iterate over the items of a List<T>, except the first, preserving the order. Is there an elegant way to do it with LINQ using a statement like: foreach (var item in list.Skip(1).TakeTheRest()) {.... I played around with TakeWhile , but was not successful. Probably there is also another, simple way of doing it?

  • KnockoutJS showing a sorted list by item category

    - by Darksbane
    I just started learning knockout this week and everything has gone well except for this one issue. I have a list of items that I sort multiple ways but one of the ways I want to sort needs to have a different display than the standard list. As an example lets say I have this code var BetterListModel = function () { var self = this; food = [ { "name":"Apple", "quantity":"3", "category":"Fruit", "cost":"$1", },{ "name":"Ice Cream", "quantity":"1", "category":"Dairy", "cost":"$6", },{ "name":"Pear", "quantity":"2", "category":"Fruit", "cost":"$2", },{ "name":"Beef", "quantity":"1", "category":"Meat", "cost":"$3", },{ "name":"Milk", "quantity":"5", "category":"Dairy", "cost":"$4", }]; self.allItems = ko.observableArray(food); // Initial items // Initial sort self.sortMe = ko.observable("name"); ko.utils.compareItems = function (l, r) { if (self.sortMe() =="cost"){ return l.cost > r.cost ? 1 : -1 } else if (self.sortMe() =="category"){ return l.category > r.category ? 1 : -1 } else if (self.sortMe() =="quantity"){ return l.quantity > r.quantity ? 1 : -1 }else { return l.name > r.name ? 1 : -1 } }; }; ko.applyBindings(new BetterListModel()); and the HTML <p>Your values:</p> <ul class="deckContents" data-bind="foreach:allItems().sort(ko.utils.compareItems)"> <li><div style="width:100%"><div class="left" style="width:30px" data-bind="text:quantity"></div><div class="left fixedWidth" data-bind="text:name"></div> <div class="left fixedWidth" data-bind="text:cost"></div> <div class="left fixedWidth" data-bind="text:category"></div><div style="clear:both"></div></div></li> </ul> <select data-bind="value:sortMe"> <option selected="selected" value="name">Name</option> <option value="cost">Cost</option> <option value="category">Category</option> <option value="quantity">Quantity</option> </select> </div> So I can sort these just fine by any field I might sort them by name and it will display something like this 3 Apple $1 Fruit 1 Beef $3 Meat 1 Ice Cream $6 Dairy 5 Milk $4 Dairy 2 Pear $2 Fruit Here is a fiddle of what I have so far http://jsfiddle.net/Darksbane/X7KvB/ This display is fine for all the sorts except the category sort. What I want is when I sort them by category to display it like this Fruit 3 Apple $1 Fruit 2 Pear $2 Fruit Meat 1 Beef $3 Meat Dairy 1 Ice Cream $6 Dairy 5 Milk $4 Dairy Does anyone have any idea how I might be able to display this so differently for that one sort?

  • Difference of function argument as (const int &) and (int & a) in C++

    - by Narek
    I know that if you write void function_name(int& a), then function will not do local copy of your variable passed as argument. Also have met in literature that you should write void function_name(const int & a) in order to say compiler, that I dont want the variable passed as argument to be copied. So my question: what is the difference with this two cases (except that "const" enshures that the variable passes will not be changed by function!!!)???

  • How do I perform this XPath query with Linq?

    - by John Hansen
    In the following code I am using XPath to find all of the matching nodes using XPath, and appending the values to a StringBuilder. StringBuilder sb = new StringBuilder(); foreach (XmlNode node in this.Data.SelectNodes("ID/item[@id=200]/DAT[1]/line[position()>1]/data[1]/text()")) { sb.Append(node.Value); } return sb.ToString(); How do I do the same thing, except using Linq to XML instead? Assume that in the new version, this.Data is an XElement object.

  • Accessing SVN repository from CCNet (CruiseControl.net) using an Active Directory user

    - by Tr1stan
    I have CCNet setup to talk to our SVN repository, which has it's ACLs setup using Active Directory groups. This is working fine, except I'm not happy with having the user name and password of the AD user stored in plain text on the CCNet instance. Is there a way to either encrypt the AD username/password, or get the CCNet service (I've tried running the service as the user and removing the the username/password section of the CCNet/SVN config) to use a domain account outside of the standard config?

  • Is it possible to edit a sound file based on frequency???

    - by K-RAN
    Just wondering if it's possible to go through a flac, mp3, wav, etc file and edit portions, or the entire file by removing sections based on a specific frequency range? So for example, I have a recording of a friend reciting a poem with a few percussion instruments in the background. Could I write a C program that goes through the entire file and cuts out everything except the vocals (human voice frequency ranges from 85-255 Hz, from what I've been reading)? Thanks in advance for any ideas!
