  • iphone/ipad adding adding and removing a subview doesnt work

    - by Mark
    Im have a slight amount of trouble adding a new view to my scene, I have the code like this: - (void) showMyDayView { NSLog(@"My Day View was touched"); MyDayViewController *temp = [[MyDayViewController alloc] initWithNibName: @"MyDayView" bundle:nil]; self.myDayViewController = temp; NSLog(@"superview: %@", [[self mainNavView] superview]); [[self mainNavView] removeFromSuperview]; NSLog(@"after removal main: %@", [self mainNavView]); NSLog(@"after removal view: %@", [self view]); NSLog(@"after removal superview: %@", [[self view] superview]); [[[self view] superview] addSubview: [self.myDayViewController view]]; [temp release]; } And when I run this code, the console says "after removal superview: (null)" so when I add the subView to the superview, nothing happens because the superview is null. Any ideas? Thanks Mark

  • How to use ShowHelp with Vista's virtualized "Program Files" folder

    - by fmunkert
    Hi, we have the problem that ShowHelp seems to fail under Vista and Windows Server 2008 if the path name of the help file contains a virtualized folder name. For example, under the German version Vista, "Program Files" is called "Programme". The call System.Windows.Forms.Help.ShowHelp(null, @"C:\Programme\Microsoft Visual Studio 9.0\Common7\Tools\spyxx.chm"); fails, wheras System.Windows.Forms.Help.ShowHelp(null, @"C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\spyxx.chm"); succeeds. If there any way in C# to convert a file path into its non-virtualized counterpart? Or is there any other solution to that problem? Regards

  • Why can't I overwrite style specified in one gtkrc file?

    - by PP
    In my Gtk+ application i am having two gtkrc files. Which i have added using: gchar *rcfile; rcfile = g_build_filename( "user", "themes", "xyz", "gtk-2.0", "gtkrc", NULL); gtk_rc_parse( rcfile ); g_free( rcfile ); rcfile = g_build_filename( "my_rc_foler", "gtkrc", NULL); gtk_rc_add_default_file( rcfile ); g_free( rcfile ); I tried to overwrite some of the styles provided by default rc file. but i fails to do so. like i have over written GtkLable style as follows In My rc file: style "my-theme-label" { xthickness = 1 ythickness = 1 bg[NORMAL] = "#FFFFFF" bg[ACTIVE] = "#FFFFFF" bg[PRELIGHT] = "#FFFFFF" bg[SELECTED] = "#FFFFFF" bg[INSENSITIVE] = "#FFFFFF" fg[NORMAL] = "#FFFFFF" fg[INSENSITIVE] = "#FFFFFF" fg[PRELIGHT] = "#FFFFFF" fg[SELECTED] = "#FFFFFF" fg[ACTIVE] = "#FFFFFF" text[NORMAL] = "#FFFFFF" text[INSENSITIVE] = "#434346" text[PRELIGHT] = "#FFFFFF" text[SELECTED] = "#FFFFFF" text[ACTIVE] = "#FFFFFF" base[NORMAL] = "#000000" base[INSENSITIVE] = "#00FF00" base[PRELIGHT] = "#0000ff" base[SELECTED] = "#FF00FF" base[ACTIVE] = "#F39638" } class "GtkLabel" style "tc-theme-label" but still it does not show any effect on GtkLables that i am using in my app.

  • Cross field validation in jsf h:datatable using p:calendar

    - by Matt Broekhuis
    I noticed this question was asked, but it has not been answered correctly. I have a datatable that has two columns start date and end date. Both contain primefaces p:calendar controls in them. I need to ensure that for each row that the date in column1 is not after the date in column2. I would like to tie this into the JSF validation framework, but I'm having trouble. i've tried marking the datatable rowStatePreserved="true" , this allows me to get the values, but something is still wrong as when it fails, all the values in the first row overwrite all the other values. What am I doing wrong, or should I be using a completely different strategy? xhtml code <h:form> <f:event type="postValidate" listener="#{bean.doCrossFieldValidation}"/> <p:dataTable id="eventDaysTable" value="#{course.courseSchedules}" var="_eventDay" styleClass="compactDataTable" > <p:column id="eventDayStartColumn"> <f:facet name="header"> Start </f:facet> <p:calendar id="startDate" required="true" value="#{_eventDay.startTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> <p:column id="eventDayEndColumn"> <f:facet name="header"> End </f:facet> <p:calendar id="endDate" required="true" value="#{_eventDay.endTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> </p:dataTable> </h:form> validationCode public void doCrossFieldValidation(ComponentSystemEvent cse) { UIData eventsDaysStable = (UIData) cse.getComponent().findComponent("eventDaysTable"); if (null != eventsDaysStable && eventsDaysStable.isRendered()) { Iterator<UIComponent> startDateCalendarIterator = eventsDaysStable.findComponent("eventDayStartColumn").getChildren().iterator(); Iterator<UIComponent> endDateCalendarIterator = eventsDaysStable.findComponent("eventDayEndColumn").getChildren().iterator(); while (startDateCalendarIterator.hasNext() && endDateCalendarIterator.hasNext()) { org.primefaces.component.calendar.Calendar startDateComponent = (org.primefaces.component.calendar.Calendar) startDateCalendarIterator.next(); org.primefaces.component.calendar.Calendar endDateComponent = (org.primefaces.component.calendar.Calendar) endDateCalendarIterator.next(); Date startDate = (Date) startDateComponent.getValue(); Date endDate = (Date) endDateComponent.getValue(); if (null != startDate && null != endDate && startDate.after(endDate)) { eventScheduleChronologyOk = false; startDateComponent.setValid(false); endDateComponent.setValid(false); } } if (!eventScheduleChronologyOk) { showErrorMessage(ProductManagementMessage.PRODUCT_SCHEDULE_OUT_OF_ORDER); } } }

  • WaitForSingleObject( )

    - by Rakesh Agarwal
    I have got myself stuck into a really amazing issue here.The code is like as below. class A { public: A(){ m_event = CreateEvent(NULL, false, false, NULL); // create an event with initial value as non-signalled m_thread = _beginthread(StaticThreadEntry, 0, this); // create a thread } static void StaticThreadEntry(A * obj) { obj->ThreadEntry(); } void ThreadEntry(); }; void A::ThreadEntry() { WaitforSingleObject(m_event,INFINITE); } int main() { A a; SetEvent(m_event); // sets the event to signalled state which causes the running thread to terminate WaitForSingleObject(m_thread, INFINITE); // waits for the thread to terminate return 0; } Problem : When the above code is run,sometimes( 1 out of 5 ) it hangs and the control gets stuck in the call to WaitforSingleObject()( inside the main function ).The code always calls SetEvent() function to ensure that the thread would terminate before calling Wait() function. I do not see any reason why it should ever hang?

  • Birt Global Integer

    - by matschie
    Hi there I have a Birt Report which read some stuff from a database. After that i want to increment a global Integer for every Detailrow that is loaded. So far i have initialized a global Integer with the following lines: importPackage(Packages.java.lang); reportContext.setPersistentGlobalVariable("minTotalPlus", new Integer(0)); After that i added the following line into a field in my detail row: reportContext.setGlobalVariable("minTotalPlus", new Integer reportContext.getGlobalVariable("minTotalPlus")) + 1); When i preview the report i get an "java.lang.NumberFormatException: null" which means that the global variable is null. Why is that so? How could I fix that?

  • Is Java assert broken?

    - by BlairHippo
    While poking around the questions, I recently discovered the assert keyword in Java. At first, I was excited. Something useful I didn't already know! A more efficient way for me to check the validity of input parameters! Yay learning! But then I took a closer look, and my enthusiasm was not so much "tempered" as "snuffed-out completely" by one simple fact: you can turn assertions off.* This sounds like a nightmare. If I'm asserting that I don't want the code to keep going if the input listOfStuff is null, why on earth would I want that assertion ignored? It sounds like if I'm debugging a piece of production code and suspect that listOfStuff may have been erroneously passed a null but don't see any logfile evidence of that assertion being triggered, I can't trust that listOfStuff actually got sent a valid value; I also have to account for the possibility that assertions may have been turned off entirely. And this assumes that I'm the one debugging the code. Somebody unfamiliar with assertions might see that and assume (quite reasonably) that if the assertion message doesn't appear in the log, listOfStuff couldn't be the problem. If your first encounter with assert was in the wild, would it even occur to you that it could be turned-off entirely? It's not like there's a command-line option that lets you disable try/catch blocks, after all. All of which brings me to my question (and this is a question, not an excuse for a rant! I promise!): What am I missing? Is there some nuance that renders Java's implementation of assert far more useful than I'm giving it credit for? Is the ability to enable/disable it from the command line actually incredibly valuable in some contexts? Am I misconceptualizing it somehow when I envision using it in production code in lieu of statements like if (listOfStuff == null) barf();? I just feel like there's something important here that I'm not getting. *Okay, technically speaking, they're actually off by default; you have to go out of your way to turn them on. But still, you can knock them out entirely.

Is there any way to hook into the Json-serializer?

  • Can I set a property on an object that is only declared on the instance type, when I don't know the

    - by WilberBeast
    Let me explain. I have a List into which I am adding various ASP.NET controls. I then wish to loop through the list and set a CssClass, however not every Control supports the property CssClass. What I would like to do is test if the underlying instance type supports the CssClass property and set it, but I'm not sure how to do the conversion prior to setting the property since I don't know the type of each Control object. I know that I can use typeof or x.GetType(), but I'm not sure how to use these to convert the controls back to the instance type in order to test for and then set the property. Actually I seem to have solved this, so I thought that I would post the code here for others. foreach (Control c in controlList) { PropertyInfo pi = c.GetType().GetProperty("CssClass"); if (pi != null) pi.SetValue(c, "desired_css_class", null); } I hope that this helps someone else as I has taken me hours to research these 2 lines of code. Cheers Steve

  • Adding STI to Existing Table...

    - by keruilin
    I want to add STI to an existing table using a custom type column. Let's call this taste_type whose corresponding model is Fruit. In the Fruit model I have: set_inheritance_column :taste_type In my migration to add STI I have: class AddSTI < ActiveRecord::Migration def self.up add_column :fruits, :taste_type, :string, :limit => 100, :null => false Fruit.reset_column_information Fruit.find_by_id(1).update_attributes({:taste_type => 'Sour'}) end def self.down remove_column :fruits, :taste_type end end When I run the migration, I get the following error: Mysql::Error: Column 'taste_type' cannot be null: ... Any idea what's going? I can get the migration to run if I comment the set_inheritance_column in the Fruit model, then uncomment it after I run the migration. Obviously, I don't want to do this, however.

  • TreeMap randomly stops properly returning values

    - by smessing
    I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

  • WPF Accessing Items inside Listbox which has a UserControl as ItemTemplate

    - by Turker
    I have Window that has a ListBox ListBox(MyListBox) has a DataTable for its DataContext ListBox's ItemSource is : {Binding} Listbox has a UserControl(MyUserControl) as DataTemplate UserControl has RadioButtons and TextBoxes (At first They're filled with values from DataTable and then user can change them) Window has one Submit Button What I want to do is, when user clicks the submit button For each ListBox Item, get the values form UserControl's TextBoxes and RadioButtons. I was using that method for this job : foreach(var element in MyListBox.Items) { var border = MyListBox.ItemContainerGenerator.ContainerFromItem(element)as FrameworkElement; MyUserControl currentControl = VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(myBorder,0) as Border,0)as ContentPresenter,0)as MyUserControl; //And use currentControl } I realised nothing when using 3-5 items in Listbox. But when I used much more items, I saw that "var border" gets "null" after some elements looped in foreach function. I found the reason here : http://stackoverflow.com/questions/1675926/listview-itemcontainergenerator-containerfromitemitem-return-null-after-20-item So what can I do now? I want to access all items and get their values sitting on user controls. Thanks

Code: public class Test { private Font printFont; private List<string> _documentLinesToPrint = new List<string>(); public void Run() { _documentLinesToPrint.Add("Test1"); _documentLinesToPrint.Add("Test2"); printFont = new Font("Arial", 10); var pd = new PrintDocument(); pd.DefaultPageSettings.Margins = new Margins(25, 25, 25, 25); pd.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 237); var printerSettings = new System.Drawing.Printing.PrinterSettings(); printerSettings.PrinterName ="Brother QL-570 LE"; pd.PrinterSettings = printerSettings; pd.PrinterSettings.Copies = 1; pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage); pd.Print(); } // The PrintPage event is raised for each page to be printed. private void pd_PrintPage(object sender, PrintPageEventArgs ev) { float linesPerPage = 0; float yPos = 0; int count = 0; float leftMargin = ev.MarginBounds.Left; float topMargin = ev.MarginBounds.Top; string line = null; // Calculate the number of lines per page. linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics); // Print each line of the file. while ((count < linesPerPage) && (count < _documentLinesToPrint.Count)) { line = _documentLinesToPrint[count]; yPos = topMargin + (count * printFont.GetHeight(ev.Graphics)); ev.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos, new StringFormat()); line = null; count++; } // If more lines exist, print another page. if (line != null) ev.HasMorePages = true; else ev.HasMorePages = false; } }

    Hi, I have this little function that opens modal window type thing. The problem is that it doesnt work on IE. All other browser its fine, but on IE, nothing happends: function showOverlayBox() { if( isOpen == false ) return; $('#full').css({ display:'block', left: ( $(window).width() - $('#full').width() )/2, top: ( $(window).height() - $('#full').height() )/2, position:'absolute' }); $('.BgCover').css({ display:'block', width: $(window).width(), height: $(window).height() }); } function doOverlayOpen() { isOpen = true; showOverlayBox(); $('.BgCover').css({opacity:0}).animate( {opacity:0.8} ); return false; } function doOverlayClose() { $('#full').css( 'display', 'none' ); $('.BgCover').animate( {opacity:0}, null, null, function() { $(this).hide(); } ); } Maybe something to do with isOpen == false?
