  • Pass a pointer to a proc as an argument

    - by user146780
    I want to pass a pointer to a procedure in c++. I tried passing this LRESULT(*)(HWND, UINT, WPARAM, LPARAM) prc but it didn't work. How is this done? Thanks HWND OGLFRAME::create(HWND parent, LRESULT(*)(HWND, UINT, WPARAM, LPARAM) prc) { if(framehWnd != NULL) { return framehWnd; ZeroMemory(&rwc,sizeof(rwc)); } } By "it didn't work" I mean it's a syntax error.

  • Flash button not reacting at all...

    - by Jerre
    Hi, I'm making a game in Flash for school. I have a few dialog boxes that work just fine! Now I need a bigger one with more buttons and with the same code, I can't even get a trace reaction... My code: On the button itself: okButton.addEventListener(MouseEvent.CLICK,MovieClip(parent).clickMyButton); In the AS file: public function clickMyButton(event:MouseEvent) { trace("Halloooo"); } Another question: How can I close (remove from stage) a child dialog box (movie clip)

  • What will this B-tree look like?

    - by Phenom
    The B-tree is of order 4, meaning that it can hold 4 pointers, and 3 keys. The following is inserted: A G I Y Since they can't all fit in one node, I know that the node will split. So I know there's going to be a root node with 2 child nodes after these things are inserted, but I don't know exactly what they'll look like.

  • How can I get Eclipse to insert tabs instead of spaces for Java content assist?

    - by Simon Nickerson
    Is there any way to persuade Eclipse to use tabs instead of spaces for indenting its built-in Java content assist proposals (such as when creating an empty method which overrides a method in the parent class)? The only setting I could find that looked relevant is in Windows/Preferences/General/Editors/Text Editors/Insert spaces for tabs, and this setting is unchecked. At the moment I have to remember to select them and re-format with <Ctrl>+<Shift>+<F>.

  • LINQ-to-SQL eagerly load entire object graph

    - by Paddy
    I have a need to load an entire LINQ-to-SQL object graph from a certain point downwards, loading all child collections and the objects within them etc. This is going to be used to dump out the object structure and data to XML. Is there a way to do this without generating a large hard coded set of DataLoadOptions to 'shape' my data?

  • Z-index bug with IE6.. can't seem to figure this one out

    - by Trip
    I am working on this gorgeous header here at : http://kayaskitchenbelmar.com/test/header.html Unfortunately, in IE6, the drop downs that come off of the Print and View buttons collapse on to a new line. This is because of the common z-index bug. I tried resolving this by making the parent div have a higher z-index and position relative with its child a lower z-index and position absolute, but that didn't seem to work. Possibly I'm missing something obvious? Thanks so much

  • Inheriting a Base Form but Paste/Cut Commands Not Captured

    - by ohu812
    I created a base form that has a specific size and an icon as a base for all forms created in my project (to be consistent in looks). The problem is, for some reason if I add a Text box to the Child form, I can no longer execute shortcuts like Copy (CTRL+C) etc into the Textbox. What should I do to handle this OTHER THAN writing code to capture those on the KeyUp control? This is also the case for RichTextBox control as well. Thanks

  • Getting a list of all children of a given commit

    - by intuited
    I'd like to run git filter-branch on all children of a given commit. This doesn't seem to be an easy task, since there doesn't appear to be a way to tell git rev-list to only return children of a particular commit. Using the .. syntax won't work because it will also include the parent commits of any merge within that range. Am I missing something here?

  • Where to put a configuration file for an Axis2 web service?

    - by Jack BeNimble
    I'd like to have my Axis2 Web Service read from a configuration file, whose name is sent as a parameter to the service. Where is the best place to put this file? And How to best access it? Examples welcome. I've checked the current directory is the Apache/Tomcat/bin file, I could put it in the parent directory, or put it into a Apache/Tomcat/conf, although this looks like it's more reserved for apache configuration itself.

What I need it for - I am writing a designer visualizer for type "object" to show the whole hierarchy of inheritance and also show which virtual methods were overridden at which level.
