  • Help using the jQuery BBQ plug-in with forms

    - by s2xi
    Hi, I have been trying to figure out how to use the jQuery BBQ plug-in. I have been able to add it to my site by copying the code from the site but I'm seeing that if I have a form in one of my tabs, I can't post any of the results successfully. Has anyone used this plug-in and gotten used to its functionality? I need help figuring out where to input my php code for form handling and have the results returned the page loaded in the tab.

  • Why SQL functions are faster than UDF

    - by Zerotoinfinite
    Though it's a quite subjective question but I feel it necessary to share on this forum. I have personally experienced that when I create a UDF (even if that is not complex) and use it into my SQL it drastically decrease the performance. But when I use SQL inbuild function they happen to work pretty faster. Conversion , logical & string functions are clear example of that. So, my question is "Why SQL in build functions are faster than UDF"? and it would be an advantage if someone can guide me how can I judge/manipulate function cost either mathematically or logically.

  • .NET - alpha-numeric representation of numbers

    - by mack369
    I'm implementing serial key functionality in my application. User needs to enter at least 64bit number in order to register the application. Because typing number like 9,223,372,036,854,775,807 will take a while I want to compress it a bit. The first guess was to code this number hexadecimally but it still is quite long (0x7FFF FFFF FFFF FFFF). Is there any standard method in .NET to code this number alphanumerically using for example: digits, upper-case and lower-case characters?

  • Efficiently Reshaping/Reordering Numpy Array to Properly Ordered Tiles (Image)

    - by Phelix
    I would like to be able to somehow reorder a numpy array for efficient processing of tiles. what I got: >>> A = np.array([[1,2],[3,4]]).repeat(2,0).repeat(2,1) >>> A # image like array array([[[1, 1, 2, 2], [1, 1, 2, 2]], [[3, 3, 4, 4], [3, 3, 4, 4]]]) >>> A.reshape(2,2,4) array([[[1, 1, 2, 2], [1, 1, 2, 2]], [[3, 3, 4, 4], [3, 3, 4, 4]]]) what I want: X >>> X array([[[1, 1, 1, 1], [2, 2, 2, 2]], [[3, 3, 3, 3], [4, 4, 4, 4]]]) to be able to do something like: >>> X[X.sum(2)>12] -= 1 >>> X array([[[1, 1, 1, 1], [2, 2, 2, 2]], [[3, 3, 3, 3], [3, 3, 3, 3]]]) Is this possible without a slow python loop? Bonus: Conversion back from X to A Edit: How can I get X from A?

  • Visual Studio 2010 Database Project does not understand Schema Names anymore?

    - by Xenan
    I just tried to upgrade a Visual Studio 2008 Database project to VS2010 and actually it is quite a mess. Hundreds of warnings, all unsolved references. It seems to boil down to Visual Studio not to understand Schema Names (aka Ownership) anymore. For example, the standard dbo schema: [$(MyDataBase)].dbo.MyTable is fine but: [$(MyDataBase)].myschema.MyTable gives an unsolved reference. It did work in VS2008. Also the abbreviation for dbo, the double dot: [$(MyDataBase)]..MyTable Doesn't work anymore. In the project property windows I restored the references to the correct servers (which were lost after the conversion) but that didn't help. This seems pretty basic but I don't have a clue how to solve this. Any help is appreciated.

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?

  • jQuery replacing an image inside a .net datalist

    - by user359409
    (submit said I was trying to post an image so I've changed image everywhere to ix I am trying to get jQuery to replace an ix inside a datalist. The original ix is the thumbnail ix of a product on a category page. The small ix I am clicking on are swatch ix for the different colors of a product. I can get it to work using a div tag around the ix tag inside the ItemTemplate. I don't need to use a div tag if I can get the imagesx to swap- I was just using it because that is sample code I found and it works for the first product in the category. <asp:HyperLink ID="ProductNav" runat="server" NavigateUrl='<%#Eval("NavigateUrl") %>'> <div id="ladiv" runat="server"> <asp:Ixx runat="server" ID="ProdThumb" /> </div> </asp:HyperLink> <asp:PlaceHolder ID="phSwatches" runat="server"></asp:PlaceHolder> The ProdThumb ix is added from the code behind and the swatches are added from the code behind swatches.Controls.Add(new LiteralControl("<table><tr>")); foreach(OptionChoice optionChoice in option.Choices) { string swatchThumbnail = string.Format("<ix ID=\"{0}\" src=\"{1}\" border=\"0\" class=\"{2}\" />","swatch" + optionChoice.OptionChoiceId.ToString(), ResolveUrl(optionChoice.ThumbnailUrl),"imgthumb"); swatches.Controls.Add(new LiteralControl("<td>")); swatches.Controls.Add(new LiteralControl(swatchThumbnail)); swatches.Controls.Add(new LiteralControl("</td>")); } swatches.Controls.Add(new LiteralControl("</tr></table>")); prodThumb.IxUrl = product.ThumbnailUrl; prodThumb.AlternateText = product.ThumbnailAltText; prodThumb.CssClass = "Thumbnail"; The jQuery is: $(function() { $("ix.imgthumb").click(function(e) { var t = $(this); var newImg = ''; $('#ladiv') .html($(newImg) ); }); }); </script> Both images are named similar, except the swatch contains "sws" and the larger one is the some only with "swl". I have spent several days searching but am not able to get it to work. If I try something like $("#<%=ladiv.ClientID %") the code can't find it. I appreciate any help.

  • return char1 + char2? Isn't it possible?

    - by pocoa
    I'm trying to return a string from a function. Which basically adds some chars together and return the string representation. string toString() { char c1, c2, c3; // some code here return c1 + c2; // Error: invalid conversion from `char' to `const char*' } it is possible to return boolean values like return c1 == 'x'. Isn't it possible to return string values? I know that it is possible to it like this: string result; result.append(c1, c2); return result; I'm new to C++ so I thought that there must be more elegant solution around.

  • How to add a title attribute to every option of an ASP.NET DropDownList

    - by zuallauz
    I'm working on an older ASP.NET project (not MVC I don't think) and one of the features they require is to view a description of an item when they hover over that item in a dropdown list. This can be simply done with HTML using the following code and making use of title text: <select> <option value="1" title="Option 1 Desc">Option 1</option> <option value="2" title="Option 2 Desc">Option 2</option> <option value="3" title="Option 3 Desc">Option 3</option> </select> Ok so how do I do this using ASP.NET DropDownList control? I have the following code: <asp:DropDownList ID="DropDownListLocation" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropDownListLocation_OnSelectedIndexChanged" CssClass="editorFieldServerControl" ClientIDMode="Static"></asp:DropDownList> And in the 'code behind' page: private void PopulateFacilityDropdown(List<FacilityAvailableByLocation> facilities, int? selectedID) { DropDownListFacility.DataSource = facilities; DropDownListFacility.DataTextField = "FacilityName"; DropDownListFacility.DataValueField = "FacilityID"; DropDownListFacility.DataBind(); DropDownListFacility.Items.Insert(0, new System.Web.UI.WebControls.ListItem("", "")); if (selectedID.HasValue && selectedID.Value > 0) DropDownListFacility.SelectedIndex = facilities.FindIndex(b => b.FacilityID == selectedID.Value); else DropDownListFacility.SelectedIndex = 0; } } Basically each facility in the list of facilities there has properties for an ID, Name, Description that I can get out. I just want to be able to put a title attribute on each <option> that gets rendered and put the description into it. Either that or be able to add a custom attribute like 'data-description' to each <option> tag then I can add the title into each option tag myself using a bit of jQuery which is easy enough. I miss the days where you could just loop through a list and output the custom dropdown code manually. Any ideas? Many thanks

  • parse this directory path without losing slash

    - by PPTim
    hi, I have a wxPython application. I am taking in a directory path from a textbox using GetValue(). I notice that while trying to parse in the directory path "C:\Documents and Settings\UserName\Desktop\InputFile.xls", python sees the string as 'C:\\Documents and Settings\UserName\\Desktop\\InputFile.xls' (missing a slash between "Settings" and "UserName). Why is it that only that slash is not correctly escaped? Once the string has been changed to 'C:\Documents and Settings\UserName\Desktop\InputFile.xls', is there a type conversion or function that can does this properly? Thanks.

  • c#: can you use a boolean predicate as the parameter to an if statement?

    - by Craig Johnston
    In C#, can you use a boolean predicate on its own as the parameter for an if statement? eg: string str = "HELLO"; if (str.Equals("HELLO")) { Console.WriteLine("HELLO"); } Will this code output "HELLO", or does it need to be: string str = "HELLO"; if (str.Equals("HELLO") == true) { Console.WriteLine("HELLO"); } If there is anything else wrong with the above code segments, please point it out.
