  • Visual Studio - "{ }" settings

    - by Xorty
    Seriously, I don't know what to google. Here's the thing, I like this java-like code writting: if (condition == true) { doSomeStuff(); } But VisualStudio "helps" me with his own "style", which I don't like and I am unable to change (after rather big time of desperate checking all settings :/) if (condition == true) { DoStuff(); } I obviously want the "{" char to be in same line where condition is ... I am using MS Visual Studio 2010 professional Any help appreciated!

  • Can I have multiple colors in a single TextBlock in WPF?

    - by Siracuse
    I have a line of text in a textblock that reads: "Detected [gesture] with an accuracy of [accuracy]" In WPF, is it possible for me to be able to change the color of the elements within a textblock? Can I have a textblock be multiple colors? For example, I would like the whole TextBlock to be black except the gesture name, which I would like to be red. Is this possible in WPF?

  • Clang LLVM doesn't generate warnings in Xcode

    - by John Gallagher
    I want lots of lovely warnings when compiling. I've set my build configuration to be based on a build config file I have. When I switch to GCC 4.0, it generates all the required warnings. As soon as I change to the Clang LLVM compiler, all the warnings disappear. Every other setting is identical. What am I missing?

  • PHP email form multiple select

    - by Justin Goodman
    I'm trying to set up a simple PHP contact form for a website and I need some help modifying the PHP to list multiple items from a select menu and would appreciate the help. I'm a graphic designer, not a developer, so a lot of this is way over my head. This is the problem area here: <label for="Events[]">Which Event(s) Will You Be Attending?</label> <div class="input-bg"> <select name="Events[]" size="6" multiple="MULTIPLE" class="required" id="Events[]"> <option value="Wednesday">Portfolio Show June 16</option> <option value="Thursday">Portfolio Show June 17</option> <option value="Saturday">Graduation Ceremony</option> <option value="Saturday Eve">Graduation Party</option> <option value="Not Sure">Not Sure</option> <option value="Not Coming">Not Coming</option> </select> </div> And here's the PHP: <?php // CHANGE THE VARIABLES BELOW $EmailFrom = "[email protected]"; $EmailTo = "[email protected]"; $Subject = "Graduation RSVP"; $Name = Trim(stripslashes($_POST['Name'])); $Email = Trim(stripslashes($_POST['Email'])); $Guests = Trim(stripslashes($_POST['Guests'])); $Events = Trim(stripslashes($_POST['Events'])); // prepare email body text $Body = ""; $Body .= "Name: "; $Body .= $Name; $Body .= "\n"; $Body .= "Email: "; $Body .= $Email; $Body .= "\n"; $Body .= "Guests: "; $Body .= $Guests; $Body .= "\n"; $Body .= "Events: "; $Body .= $Events; $Body .= "\n"; // send email $success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>"); // redirect to success page // CHANGE THE URL BELOW TO YOUR "THANK YOU" PAGE if ($success){ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation\">"; } else{ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation/error.html\">"; } ?> Any help really is appreciated!

  • two UserControls, one page, need to notify each other of updates

    - by jeriley
    I've got a user control thats used twice on the same page, each have the ability to be updated (a dropdown list gets a new item) and I'm not sure what might be the best way to handle this. One concern - this is an older system (~4+ years, datasets, .net2) and it is amazingly brittle. I did manage to have it run on 3.5 with no problems, but I've had a few run-ins with the javascript validation (~300 lines per page) throwing up all over the place when I change/add/modify controls in the parent.

  • HOW-TO Make computer sing

    - by Ofir
    Hi, I'm trying to develop an online application where the user writes some text and the software sings it back to the user. I can currently generate the audio file with the words spoken by the computer using espeak, but I have no idea how to make it sound like a song, how to add rhythm to it. I'm able to change the pitch and tempo using rubberband, but that's as far as I've gotten. Does anyone have a clue how to make this happen?

  • a4j:support within a rich:modalPanel

    - by Andy Deighton
    Hi all, I've hit a wall. I know the a4j and rich tags pretty well (I use Seam 2.2.0 and Richfaces 3.3.1). However, I'm trying to do something quite simple, but in a rich:modalPanel. It seems that rich:modalPanels do not allow Ajax events to be fired. Here's a simple breakdown: I have a h:selectOneMenu with some items in it and whose value is attached to a backing bean. Attached to that h:selectOneMenu is a a4j:support tag so that whenever the change event is fired, the backing bean should get updated. Truly simple stuff eh? However, when this h:selectOneMenu is in a rich:modalPanel the onchange event doesn't update the backing bean until the rich:modalPanel closes. I can confirm this because I'm running it in Eclipse debug mode and I have a breakpoint on the setter of the property that's hooked up to the h:selectOneMenu. This is driving me mad! This is vanilla stuff for Ajax, but rich:modalPanels don't seem to allow it. So, the question is: can I do Ajax stuff within a rich:modalPanel? I'm basically trying to use the rich:modalPanel as a form (I've tried a4j:form and h:form to no avail) that reacts to changes to the drop down (e.g. when the user changes the drop down, a certain part of the form should get reRendered). Am I trying to do something that's not possible? Here's a simplified version of the modalPanel: <rich:modalPanel id="quickAddPanel"> <div> <a4j:form id="quickAddPaymentForm" ajaxSubmit="true"> <s:decorate id="paymentTypeDecorator"> <a4j:region> <h:selectOneMenu id="paymentType" required="true" value="#{backingBean.paymentType}" tabindex="1"> <s:selectItems label="#{type.description}" noSelectionLabel="Please select..." value="#{incomingPaymentTypes}" var="type"/> <s:convertEnum/> <a4j:support ajaxSingle="true" event="onchange" eventsQueue="paymentQueue" immediate="true" limitToList="true" reRender="paymentTypeDecorator, paymentDetailsOutputPanel, quickAddPaymentForm"/> </h:selectOneMenu> </a4j:region> </s:decorate> </fieldset> <fieldset class="standard-form"> <div class="form-title">Payment details</div> <a4j:outputPanel id="paymentDetailsOutputPanel"> <h:outputText value="This should change whenever dropdown changes: #{backingBean.paymentType}"/> </a4j:outputPanel> </fieldset> </a4j:form> </div> </rich:modalPanel> Regards, Andy

  • Task managment for team

    - by Kartoch
    I'm looking for a web application to manage tasks (not necessary programming-oriented) for a small team. It must be easy to setup and maintain. It must offer file upload and mail users in case of a change. There is hundred of solutions available but most are too complex for what we want or are not "stable" (not updated since a long time, not very well programmed). i was wondering if stack overflow's folks have some recommendations...

  • Optional Argument: compile time constant issue

    - by Jack
    Why is this working: public int DoesEmailAddressExistsExcludingEmailAddressID( string emailAddress, string invitationCode, int emailAddressID = 0, int For = (int) Enums.FOR.AC) whereas this doesn't public int DoesEmailAddressExistsExcludingEmailAddressID( string emailAddress, string invitationCode, int emailAddressID = 0, int For = Enums.FOR.AC.GetHashCode()) where AC is enum. Can enums's hashcode change at runtime?

  • java background task

    - by markovuksanovic
    I was wondering which would be the most efficient approach to implement some kind of background task in java (I guess that would be some kind of nonblocking Threads). To be more precise - I have some java code and then at some point I need to execute a long running operation. What I would like to do is to execute that operation in the background so that the rest of the program can continue executing and when that task is completed just update some specific object which. This change would be then detected by other components.

  • How do you prevent IDisposable from spreading to all your classes?

    - by GrahamS
    Start with these simple classes... Let's say I have a simple set of classes like this: class Bus { Driver busDriver = new Driver(); } class Driver { Shoe[] shoes = { new Shoe(), new Shoe() }; } class Shoe { Shoelace lace = new Shoelace(); } class Shoelace { bool tied = false; } A Bus has a Driver, the Driver has two Shoes, each Shoe has a Shoelace. All very silly. Add an IDisposable object to Shoelace Later I decide that some operation on the Shoelace could be multi-threaded, so I add an EventWaitHandle for the threads to communicate with. So Shoelace now looks like this: class Shoelace { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; // ... other stuff .. } Implement IDisposable on Shoelace Buit now FxCop will complain: "Implement IDisposable on 'Shoelace' because it creates members of the following IDisposable types: 'EventWaitHandle'." Okay, I implement IDisposable on Shoelace and my neat little class becomes this horrible mess: class Shoelace : IDisposable { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; private bool disposed = false; public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } ~Shoelace() { Dispose(false); } protected virtual void Dispose(bool disposing) { if (!this.disposed) { if (disposing) { if (waitHandle != null) { waitHandle.Close(); waitHandle = null; } } // No unmanaged resources to release otherwise they'd go here. } disposed = true; } } Or (as pointed out by commenters) since Shoelace itself has no unmanaged resources, I might use the simpler dispose implementation without needing the Dispose(bool) and Destructor: class Shoelace : IDisposable { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; public void Dispose() { if (waitHandle != null) { waitHandle.Close(); waitHandle = null; } GC.SuppressFinalize(this); } } Watch in horror as IDisposable spreads Right that's that fixed. But now FxCop will complain that Shoe creates a Shoelace, so Shoe must be IDisposable too. And Driver creates Shoe so Driver must be IDisposable. and Bus creates Driver so Bus must be IDisposable and so on. Suddenly my small change to Shoelace is causing me a lot of work and my boss is wondering why I need to checkout Bus to make a change to Shoelace. The Question How do you prevent this spread of IDisposable, but still ensure that your unmanaged objects are properly disposed?

  • Mix of Arabic and English causes problems in JTextArea (Java)

    - by Dan
    I have a JTextArea which displays HTML of an Arabic web page. So it's essentially a mix of English and Arabic. In the JTextArea, with columns set to 30, certain text just disappears instead of wrapping properly. The weird thing is that if I copy the invisible text and paste it into Notepad, then I can see it in Notepad. If I change the number of columns to 40, everything displays fine. Any ideas?
