  • NSStepper ignores current NSTextField value

    - by JanX2
    I have the same initial problem as described in Integrate NSStepper with NSTextField: I need to have a NSTextField working with a NSStepper as being one control so that I can edit an integer value either by changing it directly on the text field or using the stepper up/down arrows. Using bindings as commented on by carlosb results in a usable UI. However, in the initial question carlosb describes the following: Problem is that if I edit the text field then click the stepper again it will forget about the value I manually edited and use the stepper's internal value. This is why I am posting a variation on this question again. carlosb's use of bindings doesn't solve this problem. This happens in both the current project I am working on and a test project I have created. The test project can be found at GitHub. You can download it there (even without git) via the "Download Source" button in the top right. Is there a clean way to solve this issue?

  • Insert value into selectlist

    - by William
    I need to insert a value into a selectlist. It isn't the "0" value (i.e. the first one that shows) but the next one which would be "Other". This is then used to display an "Other" textbox. My question is similiar to link text. EDIT: I don't know if this will help but here is the code: SelectList Titles; ViewData["TitleIsOther"] = TitleIsOther(Case); if ((bool)ViewData["TitleIsOther"]) { Titles = new SelectList((LookupCollection)this.LookupRepository.FetchByCategory(true, 0, 0, false, (int)Enums.LookupCategory.CaseTitles, _LoggedInUser.AccountId), "Id", "Name", "-1"); } else { Titles = new SelectList((LookupCollection)this.LookupRepository.FetchByCategory(true, 0, 0, false, (int)Enums.LookupCategory.CaseTitles, _LoggedInUser.AccountId), "Id", "Name"); } ViewData["Titles"] = Titles; The selected value of "-1" would be the "Other" option.

  • Value of text box disapears - binding viewmodel to a tab (content control)

    - by Eli Perpinyal
    Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

  • Fetched Property in XCode Data Model Editor for minimum value

    - by wal
    How do I add a Fetched Property in XCode's Data Model Editor for minimum value of one attribute?? My model: Item (name, note, storedItem) StoredItem (price, item) Item 1 ---> N StoredITem (1->N Relationship) I want that Item has a fetched property named minPrice and its value is the minimum value setted for price in the storedItems. Example: Item1 (banana, storedItem1 ... storedItem4, 10) StoredItem1 (10,item1) StoredItem2 (15,item1) StoredItem3 (30,item1) StoredItem4 (54,item1) What do I put in Destination?? StoredItem? And what do I put in Expression??

  • Understanding Flash SWC's imported into Flex Builder 3 and key framed animation

    - by Hank Scorpio
    I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar). The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this : removeChild(myPreloader); myPreloader = null; though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation. Any clues to this would be greatly appreciated.

  • Passing jQuery object and WebMethod return value to an OnSuccess function

    - by iboeno
    I am calling a WebMethod from this code: if($(this).attr("checked")) { .. MyWebMethod(variable1, variable2, onSuccessFunction); } The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do: MyWebMethod(variable1, variable2, onSuccessFunction($(this))); I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?

  • PHP - Rotate a HEX color value (eg swap all colors with "next" hex)

    - by Joe
    I have a set of hex values in an array in PHP. On my page, I have a slider which the user can "slide" to return a value between 1-100. I want to then, based on this slider value, swap all the colors in the array based on the colors "next" color based on the position in the array. An example of the same sort of thing would be like in photshop where you can rotate the hue of a layer. I want to do the same thing, in PHP, for a hex value. Any clues?

  • Composite key syntax in Boost MultiIndex

    - by Sarah
    Even after studying the examples, I'm having trouble figuring out how to extract ranges using a composite key on a MultiIndex container. typedef multi_index_container< boost::shared_ptr< Host >, indexed_by< hashed_unique< const_mem_fun<Host,int,&Host::getID> >, // ID index ordered_non_unique< const_mem_fun<Host,int,&Host::getAgeInY> >, // Age index ordered_non_unique< const_mem_fun<Host,int,&Host::getHousehold> >, // Household index ordered_non_unique< // Age & eligibility status index composite_key< Host, const_mem_fun<Host,int,&Host::getAgeInY>, const_mem_fun<Host,bool,&Host::isPaired> > > > // end indexed_by > HostContainer; My goal is to get an iterator pointing to the first of the subset of elements in HostContainer hmap that has age partnerAge and returns false to Host::isPaired(): std::pair< hmap::iterator,hmap::iterator > pit = hmap.equal_range(boost::make_tuple( partnerAge, false ) ); I think this is very wrong. How/Where do I specify the iterator index (which should be 3 for age & eligibility)? I will include other composite keys in the future. What exactly are the two iterators in std::pair? (I'm copying syntax from an example that I don't understand.) I would ideally use std::count to calculate the number of elements of age partnerAge that are eligible (return false to Host::isPaired()). What is the syntax for extracting the sorted index that meets these requirements? I'm obviously still learning C++ syntax. Thanks in advance for any help.

  • Google Maps Api android key

    - by Cookie
    Hi, I have some trouble testing my Android application which includes the google maps API. The ooficial API example worked just fine but if I copy the code into my own project it keeps saying: "The application has stopped unexpectedly". I looked up the key in the keystore several times and registered it with google. Even tried reinstalling the SDK. Does anybody know what the problem is?

  • Is Microformat's date-value-pattern fully accessible?

    - by Stephen
    Has there been an announcement (outside microformats.org) that the value-class-pattern is fully accessible? e.g. given <abbr class="value" title="2008-06-24">this Tuesday</abbr>, will a screen reader say "24 June 2008" or will it say "2008 dash 6 dash 24"? History Microformats came along, and were great, except that dates etc were stored in abbr tags: <abbr class="dtstart" title="20070312T1700-06"> March 12, 2007 at 5 PM, Central Standard Time </abbr>` This lead to screen readers doing ridiculous things as noted in hAccessibility. Now that microformats.org have released the value-class-pattern it's a lot better. But I'm left unable to find a declaration from WaSP (or another accessibility source not directly tied to microformats) that declaratively states that they are now accessible to screen readers etc.

  • @OneToMany and composite primary keys?

    - by Kris Pruden
    Hi, I'm using Hibernate with annotations (in spring), and I have an object which has an ordered, many-to-one relationship which a child object which has a composite primary key, one component of which is a foreign key back to the id of the parent object. The structure looks something like this: +=============+ +================+ | ParentObj | | ObjectChild | +-------------+ 1 0..* +----------------+ | id (pk) |-----------------| parentId | | ... | | name | +=============+ | pos | | ... | +================+ I've tried a variety of combinations of annotations, none of which seem to work. This is the closest I've been able to come up with: @Entity public class ParentObject { @Column(nullable=false, updatable=false) private String id; @OneToMany(mappedBy="object", fetch=FetchType.EAGER) @IndexColumn(name = "pos", base=0) private List<ObjectChild> attrs; ... } @Entity public class ChildObject { @Embeddable public static class Pk implements Serializable { @Column(nullable=false, updatable=false) private String objectId; @Column(nullable=false, updatable=false) private String name; @Column(nullable=false, updatable=false) private int pos; ... } @EmbeddedId private Pk pk; @ManyToOne @JoinColumn(name="parentId") private ParentObject parent; ... } I arrived at this after a long bout of experimentation in which most of my other attempts yielded entities which hibernate couldn't even load for various reasons. The error I get when I try to read one of these objects (they seem to save OK), I get an error of this form: org.hibernate.exception.SQLGrammarException: could not initialize a collection: ... And the root cause is this: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'attrs0_.id' in 'field list' I'm sure I'm missing something simple, but the documentation is not clear on this matter, and I haven't been able to find any examples of this anywhere else. Thanks!

  • Create UserControl DependencyProperty of which value can be chosen in dropdown list (as combo box)

    - by Viet
    Hello everybody, I'm a starter at WPF, now i would like to make a WPF userControl library which include a Rating bar userControl. All the steps of creating the rating Bar has been done, however i would like to add a property RatingValue: public static readonly DependencyProperty RatingValueProperty = DependencyProperty.Register("RatingValue", typeof(int), typeof(RatingControl), new FrameworkPropertyMetadata(0, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, new PropertyChangedCallback(RatingValueChanged))); public int RatingValue { get { return (int)GetValue(RatingValueProperty); } set { SetValue(RatingValueProperty, value); } } private static void RatingValueChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { //... change the rating value } that the user of my UserControl can modify by a value from 0 to 5 that are shown in a dropdown list (combo box) in the Properties windows (as some exist properties of Usercontrols like Visibility, windows style, background ...) How can i do? Thank you very much in advance, Viet

  • Documenting using Sandcastle: Refering to enum value using <see>

    - by brickner
    I'm using Sandcastle 2.4.10520 and Sandcastle Help File Builder 1.8.0 to generate a .chm help file. In my documentation, I'm using <see> tags. If I try to refer an enum like <see cref="NumberStyles"/> it works perfectly. If I try to refer an enum value like <see cref="NumberStyles.AllowTrailingWhite"/> I get a link in the documentation file, but the link leads me to an MSDN Page not found I don't get any warnings - my xml documentation is correct. I've noticed that MSDN pages that refer to an enum value also have a Page not found link. For example: UInt64.Parse Method (String, NumberStyles, IFormatProvider) refers to NumberStyles.AllowHexSpecifier and this leads to another MSDN Page not found. Should I refer to the enum instead of the enum value? What should I do to refer an enum? Is it even possible?

  • Select a subset of foreign key elements in inlineformset_factory in Django

    - by Enis Afgan
    Hello, I have a model with two foreign keys: class Model1(models.Model): model_a = models.ForeignKey(ModelA) model_b = models.ForeignKey(ModelB) value = models.IntegerField() Then, I create an inline formset class, like so: an_inline_formset = inlineformset_factory(ModelA, Model1, fk_name="model_a") and then instantiate it, like so: a_formset = an_inline_formset(request.POST, instance=model_A_object) Once this formset gets rendered in a template/page, there is ChoiceField associated with the model_b field. The problem I'm having is that the elements in the resulting drop down menu include all of the elements found in ModelB table. I need to select a subset of those based on some criteria from ModelB. At the same time, I need to keep the reference to the instance of model_A_object when instantiating inlineformset_factory and, therefore, I can't just use this example. Any suggestions?

  • Custom View embed in Gallery crashes while key press

    - by tao
    Hi there, I'd like to find some stuff to replace the Tab component, so I'd make a custom View named StringView, which has the ability to display text, and to embed it into a Gallery. But it always crashes with error "NullPointerException at InputMethodManager". I have no idea about this, any help&tip&suggest are appreciate. Detail of my issue: First I'd created a class StringView extends View: public class StringView extends View { protected final Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG); protected String mString; protected int mAscent; // Constructor public StringView(Context context, String string) { super(context); mPaint.setARGB(255, 255, 60, 10); mPaint.setTextSize(30); //mPaint.setFakeBoldText(true); mString = string; setPadding(20,15,20,15); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); int w = this.getPaddingLeft(); int h = this.getPaddingTop() - mAscent; canvas.drawText(mString, w, h, mPaint); } public void setString(String str) { mString = str; this.requestLayout(); this.invalidate(); } public String getString() { return mString; } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension(measureWidth(widthMeasureSpec), measureHeight(heightMeasureSpec)); } /** * Determines the width of this view * @param measureSpec A measureSpec packed into an int * @return The width of the view, honoring constraints from measureSpec */ private int measureWidth(int measureSpec) { int result = 0; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); if (specMode == MeasureSpec.EXACTLY) { // We were told how big to be result = specSize; } else { // Measure the text result = (int) mPaint.measureText(mString) + getPaddingLeft() + getPaddingRight(); if (specMode == MeasureSpec.AT_MOST) { // Respect AT_MOST value if that was what is called for by measureSpec result = Math.min(result, specSize); } } return result; } /** * Determines the height of this view * @param measureSpec A measureSpec packed into an int * @return The height of the view, honoring constraints from measureSpec */ private int measureHeight(int measureSpec) { int result = 0; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); mAscent = (int) mPaint.ascent(); if (specMode == MeasureSpec.EXACTLY) { // We were told how big to be result = specSize; } else { // Measure the text (beware: ascent is a negative number) result = (int) (-mAscent + mPaint.descent()) + getPaddingTop() + getPaddingBottom(); if (specMode == MeasureSpec.AT_MOST) { // Respect AT_MOST value if that was what is called for by measureSpec result = Math.min(result, specSize); } } return result; } } Second I put it in to Gallery through Adapter Gallery gallery = (Gallery) findViewById(R.id.gallery); gallery.setAdapter(new ImageAdapter(this)); ImageAdapter: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; private Context mContext; private View[] mImages = genSerielImageViews(); public ImageAdapter(Context c) { mContext = c; TypedArray a = obtainStyledAttributes(R.styleable.Gallery); mGalleryItemBackground = a.getResourceId( R.styleable.Gallery_android_galleryItemBackground, 0); a.recycle(); } private View[] genSerielImageViews() { if (true) { int N = 6; StringView[] views = new StringView[N]; for (int i=0; i<N; i++) { views[i] = new StringView(mContext, "ITEM #" + Integer.toString(i) ); } return views; } else { int N = 6; TextView[] views = new TextView[N]; for (int i=0; i<N; i++) { views[i] = new TextView( mContext ); views[i].setText("CCTV #" + Integer.toString(i) ); } return views; } } public int getCount() { return mImages.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { return mImages[position]; } } Then Compile&Run, press keypad RIGHT and I got a crash, It's turns out a weird InputMethodManager error: 03-18 07:22:33.568: ERROR/AndroidRuntime(958): Uncaught handler: thread main exiting due to uncaught exception 03-18 07:22:33.648: ERROR/AndroidRuntime(958): java.lang.NullPointerException 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.inputmethod.InputMethodManager.startInputInner(InputMethodManager.java:940) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.inputmethod.InputMethodManager.checkFocus(InputMethodManager.java:1114) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.ViewRoot.handleMessage(ViewRoot.java:1869) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.os.Handler.dispatchMessage(Handler.java:99) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.os.Looper.loop(Looper.java:123) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.app.ActivityThread.main(ActivityThread.java:4310) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at java.lang.reflect.Method.invokeNative(Native Method) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at java.lang.reflect.Method.invoke(Method.java:521) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at dalvik.system.NativeStart.main(Native Method) Thanks.

  • Algorithm for finding the smallest power of two that's greater or equal to a given value

    - by Boyan
    I need to find the smallest power of two that's greater or equal to a given value. So far, I have this: int value = 3221; // 3221 is just an example, could be any number int result = 1; while (result < value) result <<= 1; It works fine, but feels kind of naive. Is there a better algorithm for that problem? EDIT. There were some nice Assembler suggestions, so I'm adding those tags to the question.

  • Entity Framework - Foreign key constraints not added for inherited entity

    - by Tri Q
    Hello, It appears to me that a strange phenomenon is occurring with inherited entities (TPT) in EF4. I have three entities. 1. Asset 2. Property 3. Activity Property is a derived-type of Asset. Property has many activities (many-to-many) When modeling this in my EDMX, everything seems fine until I try to insert a new Property into the database. If the property does not contain any Activity, it works, but all hell breaks loose when I add some new activities to the new Property. As it turns out after 2 days of crawling the web and fiddling around, I noticed that in the EF store (SSDL) some of the constraints between entities were not picked up during the update process. Property_Activity table which links properties and activities show only one constraint FK_Property_Activity_Activity but FK_Property_Activity_Property was missing. I knew this is an Entity Framework anomoly because when I switched the relationship in the database to: Asset <-- Asset_Activity <-- Activity After an update, all foreign key constraints are picked up and the save is successful, with or without activities in the new property. Is this intended or a bug in EF? How do I get around this problem? Should I abandon inheritance altogether?

  • ASP.NET Gridview Checkbox value to DataTable

    - by Mark
    Hey all, First off, im using a checkbox to highlight a true or false value from a dataset which I want to be able to change it. Unfortunately databinding the DataTable to the GridView checkboxes doesnt work (as you probably know) as it requires it to be in "edit" mode. The way I've gotten round this is having the checkbox reading the data table value seperately rather than being databound and locked: Checked='<%# Convert.ToBoolean(Eval("myValue")) %>' So that solves checkbox values from DataTable - GridView, now I need to do the opposite having the changed checkbox values go from GridView - DataTable as it is not ready to submit it to my data source (SQL) just yet. I figure I need to run a loop through the GridView rows, thats a give'un, what I can't figure out is how to replace/update just a single value in a row of a DataTable , only the ability to add or remove an entire row by the looks of things (something I don't want to do). So can anyone offer a workaround? Or is there a way to have a databound but always editable checkbox in a gridview?

  • Dyanmic crm onSave change the value

    - by jk
    Hi I got one assignment on Dynamic CRM 4. We have one custome entity and it has one attribute called 'Issue Number' this attributes value generated by Plug-in when it save. When form will created meaning onLoad it will display blank value(text box is empty). But now we want to check that number is existing then concate with some random number. For that I wrote following javascript. if((event.Mode == 1) || (event.Mode == 2) ) { var varIssueNumber = crmForm.all.new_issueNumber.DataValue; alert(varIssueNumber); } but it is giving 'null'. Can anybody please let me know how can I get the value of text field? thanks in advance

  • Getting the PC value in ARM assembly

    - by PaulH
    I have a Windows Mobile 6 ARMV4I project where I would like to get the value of the program counter. The function is declared like this: extern "C" unsigned __int32 GetPC(); My assembly code looks like this: GetPC FUNCTION EXPORT GetPC ldr r0, [r15] ; load the PC value in to r0 mov pc, lr ; return the value of r0 ENDFUNC But, when I call the GetPC() function, I get the same number every time. So, I'm assuming my assembly isn't doing what I think it's doing. Can anybody point out what I may be doing wrong? Thanks, PaulH

  • NSNumber floatValue not equal to NSNumber value

    - by Mirkules
    Hi Everyone, First post here. Having a problem with NSNumber's floatValue method -- somehow, it returns an imprecise number. Here's the problem: I store a bunch of NSNumbers in an array, like this: NSArray *a = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0.04f], [NSNumber numberWithFloat:0.028f], [NSNumber numberWithFloat:0.016f], [NSNumber numberWithFloat:0.004f], nil]; Then I try to retrieve the first value (for example): NSNumber n = (NSNumber) [a objectAtIndex:0]; CGFloat f = [n floatValue]; In the debugger, n shows a value of 0.04 (in the summary column), but f shows a value of 0.0399999991. What am I doing wrong here? Thanks everyone.
