  • jQuery - Increase the value of a counter when a button is clicked

    - by Taimur
    Hi, I'm making a system where a user clicks a button and their score increases. There is a counter which I would like to increase the value of using jQuery (so that the page does not need to refresh) when the button is clicked. How would I go about this? <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script type="text/javascript"> $("#update").click(function() { $("#counter")++; } </script> #update is the button, #counter is the counter. In php, ++ increases something's value. What's the jQuery equivalent? Also, when the button is clicked, it needs to send a request which updates the score value in a mysql database as well, without the page refreshing. Does anyone know how I would do that? Thanks a lot UPDATE: I've tried a few of the methods below, but nothing seems to work! Do I need to change anything else for it to work? I've created a test page for it: <html> <body> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script type="text/javascript"> var count = 0; $("#update").click(function() { count++; $("#counter").html("My current count is: "+count); } </script> <button id="update" type="button">Button</button> <div id="counter">1</div> </body> </htlm>

  • Silverlight MVVM binding seems not to work

    - by Savvas Sopiadis
    Hi everybody! Building my first SL MVVM application (Silverlight4 RC) and have some issues i don't understand. Having a WPF background i don't know what is going on here: ViewModel has several properties, in which one is called SelectedRecord. This is a get only property and is defined like this: public Culture SelectedRecord { get { return culturesView.View.CurrentItem as Culture; } } As you can see it is gets the current value of a CollectionViewSource (called culturesView). So if i select a Culture, the SelectedRecord (gets a value directly from within the CollectionViewSource) as expected. (Actually there is a datagrid control bound to the CollectionViewSource, hence it is possible to change the selected item) OK. Now to the View . There are several views which access this ViewModel and in particular there is one which shows the values of the aforementioned property SelectedRecord (let's call it the EditView). To show this EditView there is a button (which has its Command property bound to an ICommand in the ViewModel) which functions (the first time) as expected. This means: 1st try : i select a record, switch to EditView, outcome: selected record values are shown (as expected!!). 2nd try: switch back to datagrid, select another record, switch to EditView, outcome: the values of the previous shown record are shown again!!! WHY?? First i thought that the SelectedRecord has not the correct value set, but i was mistaken: it HAS the correct value! So it should be shown!? What am i missing? In WPF this would work!! Thanks in advance

  • UITableView Section Headers Drawing Above Front Subview

    - by hadronzoo
    I have a UITableView whose data have sections. I display an overlay view on top of tableView that dims it when searching: - (UIView *)blackOverlay { if (!blackOverlay) { blackOverlay = [[UIView alloc] initWithFrame:[self overlayFrame]]; blackOverlay.alpha = 0.75; blackOverlay.backgroundColor = UIColor.blackColor; [tableView insertSubview:blackOverlay aboveSubview:self.parentViewController.view]; } return blackOverlay; } This works perfectly as long as tableView does not contain sections. When tableView does contain sections and the tableView updates (such as when the view reappears after popping a view off of the navigation controller stack), the section headers are rendered above blackOverlay. This leaves tableView dimmed except for the section headers. I've tried calling [tableView bringSubviewToFront:self.blackOverlay] from within viewWillAppear:, but I get the same behavior. My current work-around is returning nil for tableView section headers while the overlay is present, but this leaves whitespace gaps in the overlaid tableView where the section headers were previously. How can I insure that tableView section headers are never drawn above blackOverlay? Or, is it possible to create a view in front of tableView from within a UITableViewController subclass that is not a subview of tableView?

  • Debugging fortran code in Eclipse with Photran and GDB debugger: missing symbols

    - by tvandenbrande
    I have a program, written in fortran90, previously successfully compiled on a compaq compiler and working, that I'm now trying to compile with gfortran. I can compile the code to an .exe and run it. It works fine until a certain point in the routine and then an error is thrown. My current configuration: Windows 7 Eclipse Juno with CDT Photran Cygwin installation with gfortran compiler and GDB debugger (gdb.exe) Configurations for the debugger: GDB command set: Standard (Windows) Protocol: mi Shared libraries: don't load shared library symbols automatically (when activating this, no changes are noted). When running the debug command I get the following output: .gdbinit: No such file or directory. Reading symbols from /cygdrive/c/Users/thys/Documents/doctoraat/12_in progress/Hamfem/Debug/Hamfem.exe...done. auto-solib-add on Undefined command: "auto-solib-add". Try "help".

[New Thread 5816.0x1914] [New Thread 5816.0x654] Basicly that leaves me with 2 questions: Where can I find the .gdbinit file in the cygwin installation? Are there any other possible errors in my setup, or points to think about?

  • Efficient way to create a large number of SharePoint folders

    - by BeraCim
    Hi all: I'm currently creating a large number of SharePoint folders within a list (e.g. ~800 folders), with each folder containing a different number of items. The way it is currently done is that it programmatically reads off the content types, items, event listeners and the likes off the same folder from another web, then creates the same folder in the current web. That ran reasonably fine and fast on a dev environment. However when it goes to an environment with WFEs and farms, it slowed down a lot. I have checked that there are no leaks in the code, and that the code follows SharePoint coding best practices. At the moment I'm looking at it at the code level. From your experience, are there any efficient ways of creating a large number of SharePoint folders, lists and items? EDIT: I'm currently using SharePoint API, but will be looking at moving to using Web Service in the future. I'm interested in looking at both options though. Code wise, its just the general reading of a folder and its content types plus items and their details, then create the same folder in the same list with the same content types, then copy over the items using patch update. I want to know whether there are more efficient ways of doing the above. Thanks.

  • NotFoundException in layout editor for Android?

    - by borg17of20
    I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

  • Missing Intellisense While Describing Custom Control Properties Declaratively

    - by Albert Bori
    So, I've been working on this project for a few days now, and have been unable to resolve the issue of getting intellisense support for my custom-defined inner properties for a user control (ascx, mind you). I have seen the solution to this (using server controls, .cs mind you) many times. Spelled out in this article very well. Everything works for me while using ascx controls except intellisense. Here's the outline of my code: [PersistChildren(true)] [ParseChildren(typeof(BreadCrumbItem))] [ControlBuilder(typeof(BreadCrumbItem))] public partial class styledcontrols_buttons_BreadCrumb : System.Web.UI.UserControl { ... [PersistenceMode(PersistenceMode.InnerDefaultProperty)] public List<BreadCrumbItem> BreadCrumbItems { get { return _breadCrumbItems; } set { _breadCrumbItems = value; } } ... protected override void AddParsedSubObject(object obj) { base.AddParsedSubObject(obj); if (obj is BreadCrumbItem) BreadCrumbItems.Add(obj as BreadCrumbItem); } ... public class BreadCrumbItem : ControlBuilder { public string Text { get; set; } public string NavigateURL { get; set; } public override Type GetChildControlType(string tagName, System.Collections.IDictionary attribs) { if (String.Compare(tagName, "BreadCrumbItem", true) == 0) { return typeof(BreadCrumbItem); } return null; } } } Here's my mark up (which works fine, just no intellisense on the child object declarations): <%@ Register src="../styledcontrols/buttons/BreadCrumb.ascx" tagname="BreadCrumb" tagprefix="uc1" %> ... <uc1:BreadCrumb ID="BreadCrumb1" runat="server" BreadCrumbTitleText="Current Page"> <BreadCrumbItem Text="Home Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" /> <BreadCrumbItem Text="Secondary Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" /> </uc1:BreadCrumb> I think the issue lies with how the intellisense engine traverses supporting classes. All the working examples I see of this are not ascx, but Web Server Controls (cs, in a compiled assembly). If anyone could shed some light on how to accomplish this with ascx controls, I'd appreciate it.

  • Algorithm to detect how many words typed, also multi sentence support (Java)

    - by Alex Cheng
    Hello all. Problem: I have to design an algorithm, which does the following for me: Say that I have a line (e.g.) alert tcp 192.168.1.1 (caret is currently here) The algorithm should process this line, and return a value of 4. I coded something for it, I know it's sloppy, but it works, partly. private int counter = 0; public void determineRuleActionRegion(String str, int index) { if (str.length() == 0 || str.indexOf(" ") == -1) { triggerSuggestionList(1); return; } //remove duplicate space, spaces in front and back before searching int num = str.trim().replaceAll(" +", " ").indexOf(" ", index); //Check for occurances of spaces, recursively if (num == -1) { //if there is no space //no need to check if it's 0 times it will assign to 1 triggerSuggestionList(counter + 1); counter = 0; return; //set to rule action } else { //there is a space counter++; determineRuleActionRegion(str, num + 1); } } //end of determineactionRegion() So basically I find for the space and determine the region (number of words typed). However, I want it to change upon the user pressing space bar <space character>. How may I go around with the current code? Or better yet, how would one suggest me to do it the correct way? I'm figuring out on BreakIterator for this case... To add to that, I believe my algorithm won't work for multi sentences. How should I address this problem as well. -- The source of String str is acquired from textPane.getText(0, pos + 1);, the JTextPane. Thanks in advance. Do let me know if my question is still not specific enough.

  • Zend Framework Relationships - findDependentRowset

    - by Morten Nielsen
    Hello, When I call the method findDependentRowset, the returning rowset contains all the rows in the dependent table, and not only the rowsets that matches the reference. Hoping someone could explain this, since I was of the assumption that findDependentRowset would only return rowset matching my 'rule'? I have the following DbTable Models: class Model_DbTable_Advertisement extends Zend_Db_Table_Abstract { protected $_name = 'Advertisements'; protected $_primary = 'Id'; protected $_dependentTables = array ( 'Model_DbTable_Image', ); } class Model_DbTable_Image extends Zend_Db_Table_Abstract { protected $_name = 'Images'; protected $_primary = 'Id'; protected $_referenceMap = array( 'Images' => array( 'column' => 'AdvertisementId', 'refColumn' => 'Id', 'refTableClass' => 'Model_DbTable_Advertisement', ) ); } Now when i execute the following: (Simplified for Question sake) $model = new Model_DbTable_Advertisement(); $rowSet = $model->fetchAll(); $row = $rowSet->current(); $dRow = $row->findDependentRowset('Model_DbTable_Image'); I would expect $dRow to only contain 'Images' that has the same advertisementId as $row, but instead i receive all rows in the Images table. Any help appriciated. Kind regards, Morten

  • Spring bean's DESTROY-METHOD attribute and web-application "prototype"d bean

    - by EugeneP
    Can get work the attribute "destroy-method". First, even if I type non-existing method name into "destroy-method" attribute, Spring initialization completes fine (already strange!). Next, when a bean has a "prototype" scope, then I suppose it must be destroyed before the application is closed. That not happens, it is simply never called in my case. Though, after extracting this bean I can call this method explicitly and it does its job. Could you explain why this method is never called in my Spring 2.5 case? p.s. The method exists, it is public and has no arguments. It seems to be a more difficult task then I thought. The problem is that this destroy method is called whenever the context is closed, and this is a rare case. My question is this: I have a web app. I have a "prototype"-scoped bean. What I need is when the current session is closed, this destroy method was automatically called by Spring. I can do it by hand, but is there any solution how to make Spring do this job? It destroys the bean after the session is destroyed, it might be possible for Spring to call a method on that bean before destroying it?

  • C# Multi CheckboxList update inserts checked records but doesn't delete unchecked records

    - by DLL
    I have a multi checkboxlist on a formview. Both use queries in a tableadapter. I'm using VS 2012. When the user updates the form, I use the following code to update the checkbox data. If a user checks a new box, a new record is inserted correctly, however if the user unchecks a box the existing record is not deleted. The delete query works fine if I run it from the query builder in the table adapter, it's reaching the expected line in the code correctly, all values are correct and I receive no errors. I use a similar query to delete records when the form level data is deleted which works fine. The very last line is the one that doesn't work. Query: DELETE FROM [SLA_Categories] WHERE (([SLA_ID] = @SLA_ID) AND ([Choice_ID] = @Choice_ID)) protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) { if (FormView1.DataKey.Value != null) { Categs = (CheckBoxList)FormView1.FindControl("CheckBoxList1"); CurrentSLA_ID = (int)FormView1.DataKey.Value; } if (CurrentSLA_ID > 0) { foreach (ListItem li in Categs.Items) { // See if there's a record for the current sla in this category int CurrentChoice_ID = Convert.ToInt32(li.Value); SLADataSetTableAdapters.SLA_CategoriesTableAdapter myAdapter; myAdapter = new SLADataSetTableAdapters.SLA_CategoriesTableAdapter(); int myCount = (int)myAdapter.FindCategoryBySLA_IDAndChoice_ID(CurrentSLA_ID, CurrentChoice_ID); // If this category is checked and there is not an existing rec, insert one if (li.Selected == true && myCount < 1) { // Insert a rec for this sla myAdapter.InsertCategory(CurrentChoice_ID, CurrentSLA_ID); } // If this category is unchecked and there is and existing rec, delete it if (li.Selected == false && myCount > 0) { // Delete this rec myAdapter.DeleteCategoryBySLA_IDAndChoice_ID(CurrentChoice_ID, CurrentSLA_ID); } } } }

  • How to convert none-Latin-based encoded text into UTF-8, or make them coexist on same page?

    - by Yallaa
    Good day, I have a script that scrapes the title/description of remote pages and prints those values into a corresponding charset=UTF-8 encoded page. Here is the problem, whenever a remote page is encoded with non-Latin characters encoding like (Arabic, Russian, Chinese, Japanese etc.) the imported values print as garbled text. I've tried passing those values through either iconv or mb_convert_encoding converters but without much success. Then, I tried detecting the remote encoding first, then change my presentation page's encoding into the remote one instead of the current utf-8, which works okay with the imported values, but the other existing utf-8 content of that language on the page gets garbled instead. Example: If I try to import those values from a Russian windows-1251 into my UTF-8 encoded page which has a mix English/Russian content. I change the imported non-utf-8 string into a utf-8 using either iconv or mb_convert_encoding. I tried: $RemoteValue = iconv($RemoteEncoding, 'UTF-8', $RemoteValue); or $RemoteValue mb_convert_encoding($RemoteValue, "UTF-8", $RemoteEncoding); or $RemoteValue mb_convert_encoding($RemoteValue, "UTF-8", "auto"); without success. If I detect that the remote page is windows-1251 encoded and I change my presentation page (which already has UTF-8 encoded mixed language content) to be similar to the remote page, then the japanese utf-8 content on the existing page gets garbled... Can 2 differently encoded strings coexist on the same page (ex. utf-8 & windows-1251)? Am I using the converters correctly? any hints as to why they don't work? Is there any better way to do this? Thank you for your help

  • Modelling problem - Networked devices with commands

    - by Schneider
    I encountered a head scratching modelling problem today: We are modelling a physical control system composed of Devices and NetworkDevices. Any example of a Device is a TV. An example of a NetworkDevice is an IR transceiver with Ethernet connection. As you can see, to be able to control the TV over the internet we must connect the Device to the NetworkDevice. There is a one to many relationship between Device and NetworkDevice i.e. TV only has one NetworkDevice (the IR transceiver), but the IR transceiver may control many Devices (e.g. many TVs). So far no problem. The complicated bit is that every Device has a collection of Commands. The type of the Command (e.g IrCommand, SerialCommand - N.B. not currently modelled) depends on the type of NetworkDevice that the Device is connected to. In the current legacy system the Device has a collection of generic Commands (no typing) where fields are "interpreted" depending on the NetworkDevice type. How do I go about modelling this in OOP such that: You can only ever add a Command of the appropriate type, given the NetworkDevice the Device is attached to? If I change the NetworkDevice the Commands collection changes to the appropriate type Make it so the API is simple/elegant/intuitive to use

  • Xpath: Selecting all of an element type?

  • StructureMap problems with bidirectional/circular dependencies

    - by leozilla
    I am currently integrating StructureMap within our business layer but have problems because of bidirectional dependencies. The layer contains multiple manager where each manager can call methods on each other, there are no restrictions or rules for communication. This also includes possible circular dependencies like in the example below. I know the design itself is questionable but currently we just want StructureMap to work and will focus on further refactoring in the future. Every manager implements the IManager interface internal interface IManager { bool IsStarted { get; } void Start(); void Stop(); } And does also have his own specific interface. internal interface IManagerA : IManager { void ALogic(); } internal interface IManagerB : IManager { void BLogic(); } Here are to dummy manager implementations. internal class ManagerA : IManagerA { public IManagerB ManagerB { get; set; } public void ALogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } internal class ManagerB : IManagerB { public IManagerA ManagerA { get; set; } public void BLogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } Here is the StructureMap configuration i use atm. I am still not sure how i should register the managers so currently i use a manual registration. Maybee someone could help me with this too. For<IManagerA>().Singleton().Use<ManagerA>(); For<IManagerB>().Singleton().Use<ManagerB>(); SetAllProperties(convention => { // configure the property injection for all managers convention.Matching(prop => typeof(IManager).IsAssignableFrom(prop.PropertyType)); }); After all i cannot create IManagerA because StructureMap complians about the circular dependency between ManagerA and ManagerB. Is there an easy and clean solution to solve this problem but keep to current design? br David

  • Can addition of an ActionListener be short? Can I add arguments to the actionPerformed?

    - by Roman
    I have a big table containing a button in each cell. These buttons are very similar and do almost the same. If I add an action listener to every button in this way: tmp.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent evt) { proposition = proposition + action; SwingUtilities.invokeLater(new Runnable() { public void run() { updatePropositionPanel(); } }); } }); Actually, every action listener differ from all others by the value of the action. proposition and updatePropositionPanel are a field and a method of the class. First i thought that I can make it shorter if I do not use inner classes. So, I decided to program a new ActionListener class. But than I realized that in this case "proposition" will not be visible to the instances of this class. Then I decided to add the actionPerformed method to the current class and do that: addActionListener(this). But than I realized that I do not know how give arguments to the actionPerformed method. So, how does it work. Can I add an action listener in a short and elegent way?

  • Load external pages using jquery

    - by user1688011
    I'm trying to use jquery to load external pages into the current without reloading. Apparently everything works fine except of one little issue, I hope I'll be clear as much as possible. When I call the page 'info.php' it is loaded into the #content div. That's what the script supposed to do, the problem is that in the main page, which contains the script and the #content div, I already have some code that I want it to be executed when someone visit the page and not to be called from external page. That is actually the case but when I click on one of the links in the menu, I can't go back to the initial content.. <script> $(function() { $('#nav a').click(function() { var page = $(this).attr('href'); $('#content').load(page + '.php'); return false; }); }); </script> <ul id="nav"> <li><a href="#">Page1</a></li> <li><a href="about">About</a></li> <li><a href="contact">Contact</a></li> <li><a href="info">Info</a></li> </ul> <div id="content"> Here I have some code that I wanted to be attributed to the "Page1" </div> Do you have any suggestions how to fix this issue?

  • What's a good Java API for creating Word documents?

    - by Bill James
    I have a new app I'll be working on where I have to generate a Word document that contains tables, graphs, a table of contents and text. What's a good API to use for this? How sure are you that it supports graphs, ToCs, and tables? What are some hidden gotcha's in using them? Some clarifications: I can't output a PDF, they want a Word doc. They're using MS Word 2003 (or 2007), not OpenOffice Application is running on *nix app-server It'd be nice if I could start with a template doc and just fill in some spaces with tables, graphs, etc. Thanks for the help. Edit: Several good answers below, each with their own faults as far as my current situation. Hard to pick a "final answer" from them. Think I'll leave it open, and hope for better solutions to be created. Edit: The OpenOffice UNO project does seem to be closest to what I asked for. While POI is certainly more mainstream, it's too immature for what I want.

  • .Net Architecture challenge: The Change-prone Frankestein Model

    - by SDReyes
    Good Morning SO! We've been scratching our heads with with this interesting scenario at the office, and we're anxious to hear your ideas and approaches: We have a database, whose schema is prone to changes -lets call it Prony-. (is used to store configuration parameters for embedded devices. so if the embedded devices guy need a new table, property or relationship for the model, he should be able to adapt the schema in a easy way -happens so often- ). Prony needs a web interface to create/edit its data. We have another database containing data that also need to be loaded to the devices, after making some transformations - lets call this one Oddy- (this data it's generated by an already existent administrative web application). Finally we have Tracy, a server that communicates our DBs and our embedded devices. She should to auto-adapt herself, to our dbs schema changes and serialize the data to the devices. Nice puzzle, don't think so? : ) Our current candidates: Rady: The fast Lets create some views in Prony that make the data transformation from Oddy. then use DynamicData (or some RAD tool) to create/update a simple web interface for Prony (so he can even consult the transformated data from coming from Prony : ). About Tracy, she will need to be recompiled to update her DB schema (Entity framework should work) and use Reflection to explore recursively the schema and serialize data. Cons: We would have to recompile Tracy and the Prony's web interface. What do you think of the candidate(s)? What would you do?

  • Jekyll - How to approach asset processing (minification, spriting...)

    - by Gromix
    I recently switched to Jekyll and I find the conversion pipeline works really well. However I'm stuck on which approach to take when the process is many inputs to one output (ex: concatenating CSS files, creating image sprites...) I know several tools that can do it, that can be called either from the command line or in Ruby code directly. For ex: Jammit css sprites Compass sprites My current solution is a few Jekyll plugins that call these tools. However, it has the following problems: 1. SASS files should be processed, then concatenated/minified SASS-CSS is a Converter, and the concatenation is a Generator run on the output. Unfortunately generators are run first, which means the concatenation is always a step behind (I have to run the build twice) 2. Jekyll does not know about the source/output relationship With converters, when I run Jekyll in server mode, if I change a SASS file it automatically runs the conversion to CSS. When dealing with concatenation/spriting, I haven't found a way to do the same. I end up having to run a "normal" Jekyll build (not server auto) to update the concatenated files and sprites. Thanks for any ideas!

  • Colour manipulation of custom tags in niceEdit HTML editor ( JS / DOM )

    - by Chris
    Hi, I would like to be able to highlight, during typing and in real time, certain custom tags in the format #tag_name# within the text of a nicEdit instance ( http://nicedit.com/ ). My current attempt to implement as close to this as possible revolves around using the blur event of the editor to highlight the tags once the editor loses focus. I then use the following logic to wrap the tags in a span with a highlight class.. htmlEditor.addEvent( "blur", function( ) { str = nicEditors.findEditor( "html_content" ).getContent( ); // Remove existing spans first, leaving just the tag ( this could mess up if the html has been edited directly ) str = str.replace( /(<span class=\"highlight\">)(.[^<]+)(<\/span>)/gi, "$2" ); // Then wrap all instances of a particular tag with the highlight span str = str.replace( /#tag_name#/gi, "<span class='highlight'>#tag_name#</span>" ); nicEditors.findEditor( "html_content" ).setContent( str ); }); This is not ideal as my actual text now contains unwanted spans ( I only want the highlighting for the user's input experience, not to be saved to the database ). Obviously I could remove the spans before saving the text but the whole system is currently open to errors ( If the html is directly edited then other text may get highlighted etc ). What I would like to know is.. Is there any way to directly change the colour of the tags in the editor or DOM without using a mechanism such as this? Perhaps a way of colouring the text in memory rather than changing the HTML ? Any ideas ? Regards Chris P

  • Show image from clipboard to defalut imageviewer of windows using c#.net

    - by Rajesh Rolen- DotNet Developer
    I am using below function to make a image of current form and set it in clipboard Image bit = new Bitmap(this.Width, this.Height); Graphics gs = Graphics.FromImage(bit); gs.CopyFromScreen(this.Location, new Point(0, 0), bit.Size); Guid guid = System.Guid.NewGuid(); string FileName = guid.ToString(); //Copy that image in the clipbaord. Image imgToCopy = Image.FromFile(Path.Combine(Environment.CurrentDirectory, FileName + ".jpg")); Clipboard.SetImage(imgToCopy); Now my image is in clipboard and i am able to show it in picturebox on other form using below code : mypicturebox.Image = Clipboard.GetImage(); Now the the problem is that i want to show it in default imageviewer of that system. so for that i think using "System.Diagnostics.Process.Start" we can do that.. but i dont know, how to find default imageviewer and how to set clipboard's image in that ... please help me out... if i find solution than thats good otherwise i am thinking to save that file from clipboard to harddisk and then view it in window's default imageviewer... please help me to resolve my problem.. i am using c#.net

  • nhibernate - mapping with contraints

    - by Tobias Müller
    Hello everybody, I am having a Problem with my nhibernate-mapping and I can't find a solution by searching on stackoverflow/google/documentation. The database I am using has (amongst others) two tables. One is unit with the following fields: id enduring_id starts ends damage_enduring_id [...] The other one is damage, which has the following fields: id enduring_id starts ends [...] The units are assigned to a damage and one damage can have zero, one or more units working on it. Every time a unit moves to annother damage, the dataset is copied. The field "ends" of the old record and "starts" of the new record are set to the current time stamp, enduring_id stays the same. So if I want to know which units were working on a damage at a certain time, I do the following select: select * from unit join damage on damage.enduring_id = unit.damage_enduring_id where unit.starts <= 'time' and unit.ends = 'time' (This is not an actualy query from the database, I made it up to make clear what I mean. The the real database is a little more complex) Now I want to map it that way, so I can load all the damages which are valid at one time (starts <= wanted time <= ends) and that each of them has a Bag with all the attached units at that time (again starts <= wanted time <= ends). Is this possible within the mapping? Sorry if this is a stupid question, but I am pretty new to nhibernate and I have no clue how to do it. Thanks a lot for reading my post! Bye, Tobias
