  • How do I hide the text links over a toggleable horizontal list with background images.

    - by Sivakanesh
    I'm trying to create a UL/LI horizontal list with background images only, with no text link visible. The reason for this is so that when I over over a list item, the background would rollover and when I click on it the current item would toggle. basically it is a horizontal menu with background images that can be toggled; mimicking the job of a radio button. I have done it like this; <div id="options"> <ul id="list"> <li class="active"><a href="#" class="option1 active" id="link1"><span>XXXXX</span></a></li> <li><a href="#" class="option2" id="link2"><span>XXXXX</span></a></li> <li><a href="#" class="option3" id="link3"><span>XXXXX</span></a></li> </ul> </div> The CSS for option1, option2 and option3 simply define the background image. #options LI{list-style-type: none; display : inline} a.option1{ background:url('../images/option1.png') no-repeat;} a.option2{ background:url('../images/option2.png') no-repeat;} a.option3{ background:url('../images/option3.png') no-repeat;} a.option1, a.option2, a.option3{ background-position:top; display:inline; width:230px; height:40px; } And the hover & active css part simply sets the background position like so- a.option1:hover, a.option2:hover, a.option3:hover{ background-position:bottom; } a.active{ background-position:bottom !important; } This works fine, however on top of the background I get the words "XXXXX" as text links and I'm struggling to hide them. They are interfering with the hover action and preventing rollover (even if I replace XXXXX with a period or something short). I can't just remove the text from the link as it would hide the whole LI element. I have tried to use display:none; or text-indent:-999px but then the whole UI element becomes invisible. I can't understand what I'm doing wrong. Are you able to help? Thanks

  • How to override loading a TImage from the object inspector (at run-time)?

    - by Mawg
    Further to my previous question, which did not get a useful answer despite a bounty, I will try rephrasing the question. Basically, when the user clicks the ellipsis in the object inspector, Delphi opens a file/open dialog. I want to replace this handling with my own, so that I can save the image's path. I would have expected that all I need to do is to derive a class from TImage and override the Assign() function, as in the following code. However, when I do the assign function is never called. So, it looks like I need to override something else, but what? unit my_Image; interface uses Classes, ExtCtrls, Jpeg, Graphics; type Tmy_Image = class(Timage) private FPicture : TPicture; protected procedure OnChange(Sender: TObject); public { Public declarations } Constructor Create(AOwner: TComponent); override; procedure SetPicture(picture : TPicture); procedure Assign(Source: TPersistent); override; published { Published declarations - available in the Object Inspector at design-time } property Picture : TPicture read FPicture write SetPicture; end; // of class Tmy_Image() procedure Register; implementation uses Controls, Dialogs; procedure Register; begin RegisterComponents('Standard', [Tmy_Image]); end; Constructor Tmy_Image.Create(AOwner: TComponent); begin inherited; // Call the parent Create method Hint := 'Add an image from a file|Add an image from a file'; // Tooltip | status bar text AutoSize := True; // Control resizes when contents change (new image is loaded) Height := 104; Width := 104; FPicture := TPicture.Create(); self.Picture.Bitmap.LoadFromResourceName(hInstance, 'picture_poperty_bmp'); end; procedure Tmy_Image.OnChange(Sender: TObject); begin Constraints.MaxHeight := Picture.Height; Constraints.MaxWidth := Picture.Width; Self.Height := Picture.Height; Self.Width := Picture.Width; end; procedure Tmy_Image.SetPicture(picture : TPicture); begin MessageDlg('Tmy_Image.SetPicture', mtWarning, [mbOK], 0); // never called end; procedure Tmy_Image.Assign(Source: TPersistent); begin MessageDlg('Tmy_Image.Assign', mtWarning, [mbOK], 0); // never called end; end.

  • jQuery: Giving each matched element an unique ID

    - by AnGafraidh
    I am writing an 'inline translator' application to be used with a cloud computing platform to extend non-supported languages. The majority of this uses jQuery to find the text value, replace it with the translation, then append the element with a span tag that has an unique ID, to be used elsewhere within the application. The problem arises however, when there are more than one element, say , that have the exact same value to be translated (matched elements). What happens in the function in question is that it puts all matched elements in the same span, taking the second, third, fourth, etc. out of their parent tags. My code is pretty much like this example: <script src='jquery-1.4.2.js'></script> <script> jQuery.noConflict(); var uniqueID='asdfjkl'; jQuery(window).ready(function() { var myQ1 = jQuery("input[id~=test1]"); myClone=myQ1.clone(); myClone.val('Replaced this button'); myQ1.replaceWith('<span id='+uniqueID+'></span>'); jQuery('#'+uniqueID).append(myClone); }); </script> <table> <tr><td> <input id='test1' type='button' value="I'm a button!"></input> &nbsp; <input id='test2' type='button' value="And so am I"></input> </tr></td> <tr><td> <input id='test1' type='button' value="I'm a button!"></input> </tr></td> </table> As a workaround, I've experimented with using a loop to create a class for each span, rising in increment until jQuery("input[id~=test1]").length, but I can't seem to get anything I do to work. Is there any way to give each matched element an unique ID? My fluency in jQuery is being put to the test! Thanks for any help in advance. Aaron

  • Refactor a link and an image

    - by Mihail Stoynov
    I have to write an link with an image inside. Instead of explaining, here's the code I have now: <c:if test="${userSession.loggedUser eq null and company.image != null}"> <a onclick="${rich:component('loginPanel')}.show()"> <img src="/download.do?hash=#{company.image.hash}" /> </a> </c:if> <c:if test="${userSession.loggedUser eq null and company.image == null}"> <a onclick="${rich:component('loginPanel')}.show()"> <img src="${request.contextPath}/img/icons/logo_default.jpg" /> </a> </c:if> <c:if test="${userSession.loggedUser ne null and company.image != null}"> <a href="company.xhtml?${company.name}"> <img src="/download.do?hash=#{company.image.hash}" /> </a> </c:if> <c:if test="#{userSession.loggedUser ne null and company.image == null}"> <a href="company.xhtml?${company.name}"> <img src="${request.contextPath}/img/icons/logo_default.jpg" /> </a> </c:if> This code looks awful - there are two exact links with two exact images but combined in all possible combinations. Is there a better way? Is there a way to avoid c:if - it created tables? Update: Bozho proposes: You can replace <c:if and <a with <h:outputLink rendered="#{..}". Apart from that I don't see any other optimization. But it doesn't work. This does not render correctly: <a href=> <h:outputLink rendered="#{..} <h:outputLink rendered="#{..} </a> (the image is outside the anchor) This does render fine: <h:outputLink value=> <h:outputLink rendered="#{..} <h:outputLink rendered="#{..} </a> , but it always adds href and in two of the cases I don't want href when rendered.

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • How do I create/use a Fluent NHibernate convention to map UInt32 properties to an SQL Server 2008 da

    - by dommer
    I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32). Apologies for the code being a little long, but I'm not 100% sure what is relevant to the problem, so I'm erring on the side of caution. I think I'll need a relatively comprehensive example, as I don't seem to be able to pull the pieces together into a working solution, at present. FluentConfiguration configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008 .ConnectionString(connectionString)) .Mappings(mapping => mapping.AutoMappings.Add( AutoMap.AssemblyOf<Product>() .Conventions.Add<UInt32UserTypeConvention>())); configuration.ExposeConfiguration(x => new SchemaExport(x).Create(false, true)); namespace NHibernateTest { public class UInt32UserTypeConvention : UserTypeConvention<UInt32UserType> { // Empty. } } namespace NHibernateTest { public class UInt32UserType : IUserType { // Public properties. public bool IsMutable { get { return false; } } public Type ReturnedType { get { return typeof(UInt32); } } public SqlType[] SqlTypes { get { return new SqlType[] { SqlTypeFactory.Int32 }; } } // Public methods. public object Assemble(object cached, object owner) { return cached; } public object DeepCopy(object value) { return value; } public object Disassemble(object value) { return value; } public new bool Equals(object x, object y) { return (x != null && x.Equals(y)); } public int GetHashCode(object x) { return x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { int? i = (int?)NHibernateUtil.Int32.NullSafeGet(rs, names[0]); return (UInt32?)i; } public void NullSafeSet(IDbCommand cmd, object value, int index) { UInt32? u = (UInt32?)value; int? i = (Int32?)u; NHibernateUtil.Int32.NullSafeSet(cmd, i, index); } public object Replace(object original, object target, object owner) { return original; } } }

  • Dynamically Creating Flex Components In ActionScript

    - by Joshua
    Isn't there some way to re-write the following code, such that I don't need a gigantic switch statement with every conceivable type? Also, if I can replace the switch statement with some way to dynamically create new controls, then I can make the code smaller, more direct, and don't have to anticipate the possibility of custom control types. Before: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.containers.HBox; import mx.controls.Button; import mx.controls.Label; public function CreateControl(event:Event):void { var Type:String=Edit.text; var NewControl:Object; switch (Type) { case 'mx.controls::Label':NewControl=new Label();break; case 'mx.controls::Button':NewControl=new Button();break; case 'mx.containers::HBox':NewControl=new HBox();break; ... every other type, including unforeseeable custom types } this.addChild(NewControl as DisplayObject); } ]]> </mx:Script> <mx:Label text="Control Type"/> <mx:TextInput id="Edit"/> <mx:Button label="Create" click="CreateControl(event);"/> </mx:WindowedApplication> AFTER: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.containers.HBox; import mx.controls.Button; import mx.controls.Label; public function CreateControl(event:Event):void { var Type:String=Edit.text; var NewControl:Object= *???*(Type); this.addChild(NewControl as DisplayObject); } ]]> </mx:Script> <mx:Label text="Control Type"/> <mx:TextInput id="Edit"/> <mx:Button label="Create" click="CreateControl(event);"/> </mx:WindowedApplication>

  • ZF Autoloader to load ancestor and requested class

    - by Pekka
    I am integrating Zend Framework into an existing application. I want to switch the application over to Zend's autoloading mechanism to replace dozens of include() statements. I have a specific requirement for the autoloading mechanism, though. Allow me to elaborate. The existing application uses a core library (independent from ZF), for example: /Core/Library/authentication.php /Core/Library/translation.php /Core/Library/messages.php this core library is to remain untouched at all times and serves a number of applications. The library contains classes like class ancestor_authentication { ... } class ancestor_translation { ... } class ancestor_messages { ... } in the application, there is also a Library directory: /App/Library/authentication.php /App/Library/translation.php /App/Library/messages.php these includes extend the ancestor classes and are the ones that actually get instantiated in the application. class authentication extends ancestor_authentication { } class translation extends ancestor_translation { } class messages extends ancestor_messages { } usually, these class definitions are empty. They simply extend their ancestors and provide the class name to instantiate. $authentication = new authentication(); The purpose of this solution is to be able to easily customize aspects of the application without having to patch the core libraries. Now, the autoloader I need would have to be aware of this structure. When an object of the class authentication is requested, the autoloader would have to: 1. load /Core/Library/authentication.php 2. load /App/Library/authentication.php My current approach would be creating a custom function, and binding that to Zend_Loader_Autoloader for a specific namespace prefix. Is there already a way to do this in Zend that I am overlooking? The accepted answer in this question kind of implies there is, but that may be just a bad choice of wording. Are there extensions to the Zend Autoloader that do this? Can you - I am new to ZF - think of an elegant way, conforming with the spirit of the framework, of extending the Autoloader with this functionality? I'm not necessary looking for a ready-made implementation, some pointers (This should be an extension to the xyz method that you would call like this...) would already be enough.

  • R: Plotting a graph with different colors of points based on advanced criteria

    - by balconydoor
    What I would like to do is a plot (using ggplot), where the x axis represent years which have a different colour for the last three years in the plot than the rest. The last three years should also meet a certain criteria and based on this the last three years can either be red or green. The criteria is that the mean of the last three years should be less (making it green) or more (making it red) than the 66%-percentile of the remaining years. So far I have made two different functions calculating the last three year mean: LYM3 <- function (x) { LYM3 <- tail(x,3) mean(LYM3$Data,na.rm=T) } And the 66%-percentile for the remaining: perc66 <- function(x) { percentile <- head(x,-3) quantile(percentile$Data, .66, names=F,na.rm=T) } Here are two sets of data that can be used in the calculations (plots), the first which is an example from my real data where LYM3(df1) < perc66(df1) and the second is just made up data where LYM3 perc66. df1<- data.frame(Year=c(1979:2010), Data=c(347261.87, 145071.29, 110181.93, 183016.71, 210995.67, 205207.33, 103291.78, 247182.10, 152894.45, 170771.50, 206534.55, 287770.86, 223832.43, 297542.86, 267343.54, 475485.47, 224575.08, 147607.81, 171732.38, 126818.10, 165801.08, 136921.58, 136947.63, 83428.05, 144295.87, 68566.23, 59943.05, 49909.08, 52149.11, 117627.75, 132127.79, 130463.80)) df2 <- data.frame(Year=c(1979:2010), Data=c(sample(50,29,replace=T),75,75,75)) Here’s my code for my plot so far: plot <- ggplot(df1, aes(x=Year, y=Data)) + theme_bw() + geom_point(size=3, aes(colour=ifelse(df1$Year<2008, "black",ifelse(LYM3(df1) < perc66(df1),"green","red")))) + geom_line() + scale_x_continuous(breaks=c(1980,1985,1990,1995,2000,2005,2010), limits=c(1978,2011)) plot As you notice it doesn’t really do what I want it to do. The only thing it does seem to do is that it turns the years before 2008 into one level and those after into another one and base the point colour off these two levels. Since I don’t want this year to be stationary either, I made another tiny function: fun3 <- function(x) { df <- subset(x, Year==(max(Year)-2)) df$Year } So the previous code would have the same effect as: geom_point(size=3, aes(colour=ifelse(df1$Year<fun3(df1), "black","red"))) But it still does not care about my colours. Why does it make the years into levels? And how come an ifelse function doesn’t work within another one in this case? How would it be possible to the arguments to do what I like? I realise this might be a bit messy, asking for a lot at the same time, but I hope my description is pretty clear. It would be helpful if someone could at least point me in the right direction. I tried to put the code for the plot into a function as well so I wouldn’t have to change the data frame at all functions within the plot, but I can’t get it to work. Thank you!

  • [C++] std::string manipulation: whitespace, "newline escapes '\'" and comments #

    - by rubenvb
    Kind of looking for affirmation here. I have some hand-written code, which I'm not shy to say I'm proud of, which reads a file, removes leading whitespace, processes newline escapes '\' and removes comments starting with #. It also removes all empty lines (also whitespace-only ones). Any thoughts/recommendations? I could probably replace some std::cout's with std::runtime_errors... but that's not a priority here :) const int RecipeReader::readRecipe() { ifstream is_recipe(s_buffer.c_str()); if (!is_recipe) cout << "unable to open file" << endl; while (getline(is_recipe, s_buffer)) { // whitespace+comment removeLeadingWhitespace(s_buffer); processComment(s_buffer); // newline escapes + append all subsequent lines with '\' processNewlineEscapes(s_buffer, is_recipe); // store the real text line if (!s_buffer.empty()) v_s_recipe.push_back(s_buffer); s_buffer.clear(); } is_recipe.close(); return 0; } void RecipeReader::processNewlineEscapes(string &s_string, ifstream &is_stream) { string s_temp; size_t sz_index = s_string.find_first_of("\\"); while (sz_index <= s_string.length()) { if (getline(is_stream,s_temp)) { removeLeadingWhitespace(s_temp); processComment(s_temp); s_string = s_string.substr(0,sz_index-1) + " " + s_temp; } else cout << "Error: newline escape '\' found at EOF" << endl; sz_index = s_string.find_first_of("\\"); } } void RecipeReader::processComment(string &s_string) { size_t sz_index = s_string.find_first_of("#"); s_string = s_string.substr(0,sz_index); } void RecipeReader::removeLeadingWhitespace(string &s_string) { const size_t sz_length = s_string.size(); size_t sz_index = s_string.find_first_not_of(" \t"); if (sz_index <= sz_length) s_string = s_string.substr(sz_index); else if ((sz_index > sz_length) && (sz_length != 0)) // "empty" lines with only whitespace s_string.clear(); } Some extra info: the first s_buffer passed to the ifstream contains the filename, std::string s_buffer is a class data member, so is std::vector v_s_recipe. Any comment is welcome :)

  • Excel 2008 Cant Parse HTML

    - by VictorV
    I need to export a gridview to excel, I put the return html code from the gridview to a HtmlTextWriter and put this into the response. The result file work fine in excel, excel can parse the html and the result is readable, work perfect on excel 2003 and 2007, but in some machines with Excel 2008 (MACOS) excel shows only the raw html code and can't process this html code. Any idea to configure excel? This is the code to convert: public static void ToExcel(GridView gridView, string fileName) { HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Buffer = true; fileName = fileName.Replace(".xls", string.Empty) + ".xls"; response.AddHeader("content-disposition", "attachment;filename=" + fileName); response.Charset = ""; response.ContentEncoding = Encoding.Unicode; response.BinaryWrite(Encoding.Unicode.GetPreamble()); response.ContentType = MimeTypes.GetContentType(fileName); StringWriter sw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(sw); gridView.AllowPaging = false; //gridView.DataBind(); //Change the Header Row back to white color gridView.HeaderRow.Style.Add("background-color", "#FFFFFF"); //Apply style to Individual Cells for (int i = 0; i < gridView.HeaderRow.Cells.Count; i++) { gridView.HeaderRow.Cells[i].Style.Add("background-color", "yellow"); } for (int i = 0; i < gridView.Rows.Count; i++) { GridViewRow row = gridView.Rows[i]; //Change Color back to white row.BackColor = System.Drawing.Color.White; //Apply text style to each Row row.Attributes.Add("class", "textmode"); //Apply style to Individual Cells of Alternating Row if (i % 2 != 0) { for (int j = 0; j < row.Cells.Count; j++) { row.Cells[j].Style.Add("background-color", "#C2D69B"); } } } gridView.RenderControl(hw); //style to format numbers to string string style = @"<style> .textmode { mso-number-format:\@; } </style>"; response.Write(style); response.Output.Write(sw.ToString()); response.Flush(); response.End(); }

  • ASP.Net MVC + Live validation - how come the flagged text are all over the place?

    - by melaos
    hi guys, this is an asp.net mvc project and <% using (Html.BeginForm("ProductAdded", "Home")) { % Register Your Product <%= ViewData["MainHeader"]% <p><%=ViewData["IntroText"]%></p> <div style="display: none;"> <div id="regionThreePane"> <table border="0" cellpadding="0" cellspacing="0" frame="void" style="width: 100%"> <tr> <td width='250px'><select name="ProdLBox1" id="ProdLBox1" class="ProdLBox1" size="8"></select></td> <td width='250px'><select name="ProdLBox2" id="ProdLBox2" class="ProdLBox2" size="8"></select></td> <td width='250px'><select name="ProdLBox3" id="ProdLBox3" class="ProdLBox3" size="8"></select></td> </tr> </table> </div> i'm using live validation for my client side validation. var v_fname = new LiveValidation('Customer_FirstName', { validMessage: " " }, { onlyOnSubmit: true }); v_fname.add(Validate.Presence, { failureMessage: enterfirstname}); var v_lname = new LiveValidation('Customer_LastName', { validMessage: " " }); v_lname.add(Validate.Presence, { failureMessage: enterlastname }); var v_email = new LiveValidation('Customer_Email', { validMessage: " " }); v_email.add(Validate.Presence, { failureMessage: enteremail, validMessage: " " }); v_email.add(Validate.Email, { failureMessage: entervalidemail}); and what i notice is that after doing some button call: $(".btnAddProduct").click(function() { //Check first to see if there's anything to be added if (parseFloat($(".tboAddProduct").val()) < 1) { //TO DO: to replace with localized text var selectProductError = "Please select a product first"; $("#validationSummary").text(selectProductError); //alert("Please select a product first"); return false; } $(".PanelProductReg").show(); addProductRow($(".tboAddProductId").val(), $("#tboAddProduct").val()); }); what will happen is that the validation tags will start to appear for the whole page for all the input which are tag for the live validation. instead of just appearing when the controls are being higlighted and onblur. i'm using some ajax calls to get data and a lot of jquery to dynamically do the gui stuff. could any of this be causing some sort of an internal conflict? thanks

  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • Ping remote server and wait to get data

    - by infinity
    Hi I'm building my first application for android and I've reached a point where I can't find a solution even have no idea what to search for in Google. So the problem: I am pinging a remote server with GET request through the application passing some parameters like file_id. Then the server gives back confirmation if the file exists or error otherwise, both in plain text. The error string is $$$ERROR$$$. Actually the confirmation is JSON string that holds the path to the file. If the file doesn't exists on the server it generated the error message and start downloading the file and processing it which normally takes 10-30 seconds. What would be the best way to check if the file is ready for download? I have DownloadFile class that extends AsyncTask but before I reach the point to download the file I need the URL which is dependant on the previous request which is in the main class in the UI thread. Here is some code: public class MainActivity extends Activity { private String getInfo() { // Create a new HttpClient and Post Header HttpClient httpClient = new DefaultHttpClient(); HttpGet httpPost = new HttpGet(infoUrl); StringBuilder sb = null; String data; JSONObject jObject = null; try { HttpResponse response = httpClient.execute(httpPost); // This might be equal "$$$ERROR$$$" if no file exists sb = inputStreamToString(response.getEntity().getContent()); } catch(ClientProtocolException e) { // TODO Auto-generated catch block Log.v("Error: pushItem ClientProtocolException: ", e.toString()); } catch (IOException e) { // TODO Auto-generated catch block Log.v("Error: pushItem IOException: ", e.toString()); } // Clean the data to be complaint JSON format data = sb.toString().replace("info = ", ""); try { jObject = new JSONObject(data); data = jObject.getString("h"); fileTitle = jObject.getString("title"); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } downloadUrl = String.format(downloadUrl, fileId, data); return downloadUrl; } } So my idea was to get the content and if equal to $$$ERROR$$$ go into loop until JSON data is passed but I guess there is better solution. Note: I don't have control over the server output so have to deal with what I have.

  • Why isn't my File.Move() working?

    - by yeahumok
    I'm not sure what exactly i'm doing wrong here...but i noticed that my File.Move() isn't renaming any files. Also, does anybody know how in my 2nd loop, i'd be able to populate my .txt file with a list of the path AND sanitized file name? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Text.RegularExpressions; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { //recurse through files. Let user press 'ok' to move onto next step string[] files = Directory.GetFiles(@"C:\Documents and Settings\jane.doe\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.Write(file + "\r\n"); } Console.WriteLine("Press any key to continue..."); Console.ReadKey(true); //End section //Regex -- find invalid chars string pattern = " *[\\~#%&*{}/<>?|\"-]+ *"; string replacement = " "; Regex regEx = new Regex(pattern); string[] fileDrive = Directory.GetFiles(@"C:\Documents and Settings\jane.doe\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); List<string> filePath = new List<string>(); //clean out file -- remove the path name so file name only shows string result; foreach(string fileNames in fileDrive) { result = Path.GetFileName(fileNames); filePath.Add(result); } StreamWriter sw = new StreamWriter(@"C:\Documents and Settings\jane.doe\Desktop\~Test Folder for [SharePoint] %testing\File_Renames.txt"); //Sanitize and remove invalid chars foreach(string Files2 in filePath) { try { string sanitized = regEx.Replace(Files2, replacement); sw.Write(sanitized + "\r\n"); System.IO.File.Move(Files2, sanitized); System.IO.File.Delete(Files2); } catch (Exception ex) { Console.Write(ex); } } sw.Close(); } } } I'm VERY new to C# and trying to write an app that recurses through a specific drive, finds invalid characters (as specified in the RegEx pattern), removes them from the filename and then write a .txt file that has the path name and the corrected filename. Any ideas?

  • TestNG - Factories and Dataproviders

    - by Tim K
    Background Story I'm working at a software firm developing a test automation framework to replace our old spaghetti tangled system. Since our system requires a login for almost everything we do, I decided it would be best to use @BeforeMethod, @DataProvider, and @Factory to setup my tests. However, I've run into some issues. Sample Test Case Lets say the software system is a baseball team roster. We want to test to make sure a user can search for a team member by name. (Note: I'm aware that BeforeMethods don't run in any given order -- assume that's been taken care of for now.) @BeforeMethod public void setupSelenium() { // login with username & password // acknowledge announcements // navigate to search page } @Test(dataProvider="players") public void testSearch(String playerName, String searchTerm) { // search for "searchTerm" // browse through results // pass if we find playerName // fail (Didn't find the player) } This test case assumes the following: The user has already logged on (in a BeforeMethod, most likely) The user has already navigated to the search page (trivial, before method) The parameters to the test are associated with the aforementioned login The Problems So lets try and figure out how to handle the parameters for the test case. Idea #1 This method allows us to associate dataproviders with usernames, and lets us use multiple users for any specific test case! @Test(dataProvider="players") public void testSearch(String user, String pass, String name, String search) { // login with user/pass // acknowledge announcements // navigate to search page // ... } ...but there's lots of repetition, as we have to make EVERY function accept two extra parameters. Not to mention, we're also testing the acknowledge announcements feature, which we don't actually want to test. Idea #2 So lets use the factory to initialize things properly! class BaseTestCase { public BaseTestCase(String user, String password, Object[][] data); } class SomeTest { @Factory public void ... } With this, we end up having to write one factory per test case... Although, it does let us have multiple users per test-case. Conclusion I'm about fresh out of ideas. There was another idea I had where I was loading data from an XML file, and then calling the methods from a program... but its getting silly. Any ideas?

  • How to prevent mvn jetty:run from executing test phase?

    - by tputkonen
    We use MySQL in production, and Derby for unit tests. Our pom.xml copies Derby version of persistence.xml before tests, and replaces it with the MySQL version in prepare-package phase: <plugin> <artifactId>maven-antrun-plugin</artifactId> <version>1.3</version> <executions> <execution> <id>copy-test-persistence</id> <phase>process-test-resources</phase> <configuration> <tasks> <!--replace the "proper" persistence.xml with the "test" version--> <copy file="${project.build.testOutputDirectory}/META-INF/persistence.xml.test" tofile="${project.build.outputDirectory}/META-INF/persistence.xml" overwrite="true" verbose="true" failonerror="true" /> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> <execution> <id>restore-persistence</id> <phase>prepare-package</phase> <configuration> <tasks> <!--restore the "proper" persistence.xml--> <copy file="${project.build.outputDirectory}/META-INF/persistence.xml.production" tofile="${project.build.outputDirectory}/META-INF/persistence.xml" overwrite="true" verbose="true" failonerror="true" /> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> The problem is, that if I execute mvn jetty:run it will execute the test persistence.xml file copy task before starting jetty. I want it to be run using the deployment version. How can I fix this?

  • jQuery - Form input return confirm to delete

    - by bruno
    hello guys. I struggled a lot before posting here :) now, I want to replace my default javascript confirmation for deleting a file. I saw a lot of examples here, but no example with form input. Now I have his form: <form action="delete.php" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="<{$lang_del_pic}>" onclick="javascript: return confirm('<{$lang_confirm_del}>');" /> </form> Now, I did everything, I have this div: <div id="dialog-confirm" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p> </div> this javascript: <script type="text/javascript"> $(document).ready(function() { $("#dialog").dialog({ autoOpen: false, modal: true }); }); $(".confirmLink").click(function(e) { e.preventDefault(); var targetUrl = $(this).attr("href"); $("#dialog").dialog({ buttons : { "Confirm" : function() { window.location.href = targetUrl; }, "Cancel" : function() { $(this).dialog("close"); } } }); $("#dialog").dialog("open"); }); </script> and this new form: <form name="dialog-confirm" id="dialog-confirm" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="" id="opener" /> </form> On press, I call successfuly the jQuery modal diolog, and everything works, but somehow, when I press 'delete all' the script tells me - "the script is called without the necessary parameters" Now I guess I am failig to send the pic ID to be deleted with the jQuery, .. but do not know how to fix it. Any ideas ?

  • Serialize JavaScript's navigator object

    - by kappa
    Hi, I'm creating a page to help diagnose the problem our users are experiencing with our web pages (you know, asking a user "What browser are you using?" usually leads to "Internet"). This page already submits to me all the HTTP headers and now I'm trying to have JavaScript give some more informations, so I thought it would be great to have the user's navigator JavaScript object and I started looking how to serialize it so I can submit it through a form. The problem is I'm not able to serialize the navigator object using any JSON library I know of, everyone returns an empty object (?!), so I decided to write an ad-hoc serializer. You can find the code here: <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function serialize (object) { var type = typeof object; if (object === null) { return '"nullValue"'; } if (type == 'string' || type === 'number' || type === 'boolean') { return '"' + object + '"'; } else if (type === 'function') { return '"functionValue"'; } else if (type === 'object') { var output = '{'; for (var item in object) { if (item !== 'enabledPlugin') { output += '"' + item + '":' + serialize(object[item]) + ','; } } return output.replace(/\,$/, '') + '}'; } else if (type === 'undefined') { return '"undefinedError"'; } else { return '"unknownTypeError"'; } }; $(document).ready(function () { $('#navigator').text(serialize(navigator)); }); </script> <style type="text/css"> #navigator { font-family: monospaced; } </style> <title>Serialize</title> </head> <body> <h1>Serialize</h1> <p id="navigator"></p> </body> </html> This code seems to work perfectly in Firefox, Opera, Chrome and Safari but (obviously) doesn't work in Internet Explorer (at least version 8.0), it complains that "Property or method not supported by the object" at line for (var item in object) {. Do you have any hint on how to fix the code or how to reach the goal (serialize the navigator object) by other means?

    - by peter
    I want to implement a UAC prompt for an application in visualc++ the operating system is 32bit x7460(2processor) Windowsserver 2008 the exe is myproject.exe through manifest.. Here for testing i wl build the application in Windows XP OS and copy the exe in to system containg the Windowsserver 2008 machine and replace it So what i did is i added a manifest like this name of that is myproject.exe.manifest My project has 3 folders like Headerfile,Resourcefile and Source file.I added this manifest(myproject.exe.manifest) in the Sourcefile folder containing other cpp and c code <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="4.0" processorArchitecture="X7460" name="myproject" type="win32"/> <description>myproject Problem</description> <!-- Identify the application security requirements. --> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/> </requestedPrivileges> </security> </trustInfo> </assembly> then i added this line of code in Resourcefile(.rc).Means one header file is there(Myproject.h).I added the line of code there #define MANIFEST_RESOURCE_ID 1 MANIFEST_RESOURCE_ID RT_MANIFEST "myproject.exe.manifest" Finally i did the following step Under Project, select Properties. 3.

  • Javascript problem with a global external link confirmation alert

    - by OverDrive
    Below is the code from a plugin for Joomla. It works on it's own and it's purpose is to detect external links on the page and force them into new browser windows using _blank. I've tried for about an hour (I don't know javascript well) but I can't seem to figure out how to get an onclick function working. End result, I want to add to this script the ability of a confirmation dialog, shown in the 2nd code section. An external link, when clicked, will pop up the confirmation dialog, and if it says yes, they will be able to get to the external URL, opening in a new window. Otherwise, it cancels, and does nothing. When I create a link with onclick="return ExitNotice(this.href);" within it it works perfectly, but since my website has multiple people submitting input, I'd like the confirmation box global. this.blankwin = function(){ var hostname = window.location.hostname; hostname = hostname.replace("www.","").toLowerCase(); var a = document.getElementsByTagName("a"); this.check = function(obj){ var href = obj.href.toLowerCase(); return (href.indexOf("http://")!=-1 && href.indexOf(hostname)==-1) ? true : false; }; this.set = function(obj){ obj.target = "_blank"; obj.className = "blank"; }; for (var i=0;i<a.length;i++){ if(check(a[i])) set(a[i]); }; }; this.addEvent = function(obj,type,fn){ if(obj.attachEvent){ obj['e'+type+fn] = fn; obj[type+fn] = function(){obj['e'+type+fn](window.event );} obj.attachEvent('on'+type, obj[type+fn]); } else { obj.addEventListener(type,fn,false); }; }; addEvent(window,"load",blankwin); Second Part /* ---------- OnClick External Link Notice ---------- */ function ExitNotice(link,site,ltext) { if(confirm("-----------------------------------------------------------------------\n\n" + "You're leaving the HelpingTeens.org website. HelpingTeens.org\ndoes not " + "control this site and its privacy policies may differ\nfrom our own. " + "Thank you for using our site.\n\nYou will now access the following link:\n" + "\n" + link + "\n\nPress \'OK\' to proceed, or press \'Cancel\' to remain here." + "\n\n-----------------------------------------------------------------------")) { return true; } history.go(0); return false; } A) Can anyone help me fix this problem? or B) Is there a better solution?

  • Jquery Var Returned As object

    - by alex
    I'm trying to pass a variable from one function to another, but the var elmId is being returned as an object and giving an error. When we click on any of the generated divs we should be able to change the size of the div by choosing a width / height value from the drop down menus. I'm trying to pass the clicked div id which is elmId to function displayVals but it is not working. If we replace "#"+elmId in the function displayVals with the actual id of the first div created with is "#divid1" then it works. Why is the value of var elmId not being passed to displayVals <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/base/jquery-ui.css" type="text/css" media="all" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js" type="text/javascript"></script> <style> .aaa{width:100px; height:100px; background-color:#ccc;} button{width:100px; height:20px;} </style> <button class="idiv">div</button> <select id="width"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <select id="height"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <p></p> <script type="text/javascript"> var divId = 1; $("button").click(function(){ var elm = $('<div id=divid' + divId + ' class=aaa></div>'); elm.appendTo('p'); divId++; }); $("p").click(function(e){ var elmType = $(e.target)[0].nodeName, elmId = $(e.target)[0].id; return displayVals(elmId); }); function displayVals(elmId) { var iwidth = $("#width").val(); var iheight = $("#height").val(); $("#"+elmId).css({width:iwidth, height:iheight}); console.log(elmId); } $("select").change(displayVals); displayVals(); </script>

  • Using jQuery to store basic text string in mySQL base?

    - by Kenny Bones
    Could someone point me in the right direction here? Basically, I've got this jQuery code snippet: $('.bggallery_images').click(function () { var newBG = "url('" + $(this).attr('src'); var fullpath = $(this).attr('src'); var filename = fullpath.replace('img/Bakgrunner/', ''); $('#wrapper').css('background-image', newBG); // Lagre til SQL $.ajax({ url: "save_to_db.php", // The url to your function to handle saving to the db data: filename, dataType: 'Text', type: 'POST', // Could also use GET if you prefer success: function (data) { // Just for testing purposes. alert('Background changed to: ' + data); } }); }); This is being run when I click a certain button. So it's actually within a click handler. If I understand this correctly, this snippet takes the source if the image I just clicked and strips it so I end up with only the filename. If I do an alert(filename), I get the filename only. So this is working ok. But then, it does an ajax call to a php file called "save_to_db.php" and sends data: filename. This is correct right? Then, it does a callback which does an alert + data. Does this seem correct so far? Cause my php file looks like this: <?php require("dbconnect2.php"); $uploadstring = $_POST['filename']; $sessionid = $_SESSION['id']; echo ($sessionid); mysql_query("UPDATE brukere SET brukerBakgrunn = '$uploadstring' WHERE brukerID=" .$_SESSION['id']); mysql_close(); ?> When I click the image, the jQuery snippet fires and I get the results of this php file as output for the alert box. I think that the variables somehow are empty. Because notice the echo($sessionid); which is a variable I've created just to test what the session ID is. And it returns nothing. What could be the issue here? Edit: I just tried to echo out the $uploadstring variable as well and it also returns nothing. It's like the jQuery snippet doesn't even pass the variable on to the php file?

  • Help with code optimization

    - by Ockonal
    Hello, I've written a little particle system for my 2d-application. Here is raining code: // HPP ----------------------------------- struct Data { float x, y, x_speed, y_speed; int timeout; Data(); }; std::vector<Data> mData; bool mFirstTime; void processDrops(float windPower, int i); // CPP ----------------------------------- Data::Data() : x(rand()%ScreenResolutionX), y(0) , x_speed(0), y_speed(0), timeout(rand()%130) { } void Rain::processDrops(float windPower, int i) { int posX = rand() % mWindowWidth; mData[i].x = posX; mData[i].x_speed = WindPower*0.1; // WindPower is float mData[i].y_speed = Gravity*0.1; // Gravity is 9.8 * 19.2 // If that is first time, process drops randomly with window height if (mFirstTime) { mData[i].timeout = 0; mData[i].y = rand() % mWindowHeight; } else { mData[i].timeout = rand() % 130; mData[i].y = 0; } } void update(float windPower, float elapsed) { // If this is first time - create array with new Data structure objects if (mFirstTime) { for (int i=0; i < mMaxObjects; ++i) { mData.push_back(Data()); processDrops(windPower, i); } mFirstTime = false; } for (int i=0; i < mMaxObjects; i++) { // Sleep until uptime > 0 (To make drops fall with randomly timeout) if (mData[i].timeout > 0) { mData[i].timeout--; } else { // Find new x/y positions mData[i].x += mData[i].x_speed * elapsed; mData[i].y += mData[i].y_speed * elapsed; // Find new speeds mData[i].x_speed += windPower * elapsed; mData[i].y_speed += Gravity * elapsed; // Drawing here ... // If drop has been falled out of the screen if (mData[i].y > mWindowHeight) processDrops(windPower, i); } } } So the main idea is: I have some structure which consist of drop position, speed. I have a function for processing drops at some index in the vector-array. Now if that's first time of running I'm making array with max size and process it in cycle. But this code works slower that all another I have. Please, help me to optimize it. I tried to replace all int with uint16_t but I think it doesn't matter.

  • Why is FF on OS X loosing jQuery-UI in click event handler?

    - by Jean-François Beauchamp
    In a web page using jQUery 1.7.1 and jQUery-UI 1.8.18, if I output $.ui in an alert box when the document is ready, I get [object Object]. However when using Firefox, if I output $.ui in a click event handler, I get 'undefined' as result. With other browsers (latest versions of IE, Chrome and Safari), the result is still [object Object] when clicking on the link. Here is my HTML Page: <!doctype html> <html> <head> <title></title> <script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.18.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { alert($.ui); // ALERT A $(document).on("click", ".dialogLink", function () { alert($.ui); // ALERT B return false; }); }); </script> </head> <body> <a href="#" class="dialogLink">Click me!</a> </body> </html> In this post, I reduced to its simplest form another problem I was having described here: $(this).dialog is not a function. I created a new post for the sake of clarity, since the real question is different from the original one now that pin-pointed where the problem resided. UPDATE: IF I replace my alerts with simply alert($); I get this result for alert A: function (selector, context) { return new jQuery.fn.init(selector, context, rootjQuery); } and this one for alert B: function (a, b) { return new d.fn.init(a, b, g); } This does not make sense to me, although I may not be understanding well enough what $ is... UPDATE 2: I can only reproduce this problem using Firefox on OS X. On Firefox running on Windows 7, everything is fine.
