  • WCF wrapper COM object

    - by LarryR
    I have a third party COM component (they don't offer a .Net assy), that has the additional feature that it only works under x86 compile. I am trying to wrap this in a WCF service, but if I select x86, the service won't start (System.BadImageFormatException). Any workarounds for this ? Thanks Larry

  • Checking whether an object exists in StructureMap container

    - by Kevin Pang
    I'm using StructureMap to handle the creation of NHibernate's ISessionFactory and ISession. I've scoped ISessionFactory as a singleton so that it's only created once for my web app and I've scoped ISession as a hybrid so that it will only be opened once per web request. I want to make sure that at the end of each web request, I properly dispose of ISession if it was created for that web request. I figured I could put some code in my Application_EndRequest routine to first check if an ISession was created, and if so, call ISession.Dispose. My current workaround is to just open up an ISession on Application_BeginRequest then dispose of it on Application_EndRequest, but that seems somewhat wasteful in that static file requests for images and css files and whatnot will create an ISession without ever using it. I know that the overall performance hit is negligable since ISessions are very lightweight, but it's getting annoying seeing all those ISessions being created inside NHProf.

  • creative way for implementing Data object with it's corespanding buisness logic class in java

    - by ekeren
    I have a class that need to be serialized (for both persistentcy and client-server communication) for simplicity reasons lets call the classes Business a BusinessData and I prefix for their Interfaces. All the getter and setter are delegated from Business class to BusinessData class. I thought about implementing IBusinessData interface that will contain all the getter and setters and IBusiness interface that will extend it. I can either make Business extend BuisnessData so I will not need to implement all getter and setter delegates, or make some abstract class ForwardingBusinessData that will only delegate getter and setters. Any of the above option I loose my hierarchy freedom, does any of you have any creative solution for this problem... I also reviewed DAO pattern: http://java.sun.com/blueprints/patterns/DAO.html

  • Forcing deallocation of large cache object in Java

    - by Jack
    I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java? I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..

  • Running out of memory but not seeing excessive object allocation in Instruments

    - by Scotty Allen
    I have an iPad app that's crashing due to low memory. However, Instruments doesn't show any significant amount of memory allocated using ObjectAlloc - it stays under 1MB for the lifetime of the application. Leaks shows less than 1kB leaked over the course of the run. Memory monitor shows the free memory on the devices drop significantly with use, eventually dropping to the point that it's out of memory. Here's a screenshot from Instruments: I'm totally stumped. As far as I can tell, this basically says that as far as my app is concerned, I'm never using more than about 750kB, but that the device is still running out of physical memory, which is causing my app to crash/force exit. I'm new to debugging memory issues with XCode. Am I measuring this wrong? Is there another way to see where this memory is going?

  • Opengl: use a texture only to give alpha channel to a colored object

    - by Damian
    I'm new at OpenGL and I can't find out how to do this: I want to render a letter and be able to change it's color, so I have a texture with the letter on a transparent background. I managed to render it using this code: glEnable(GL_BLEND) glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) But that renders the letter in black, as it's on the texture. How can I render it with the color setted with glColor4f?

  • how to get the value from a CSS class object in javascript

    - by amit
    I have to select an <a> element from the given class of objects. when i click on the anchor tag in the showcase_URL class, i want the jquery function to get the value from <a> tag. How can this be done? I cannot make this an id as I am running a while loop to construct all the elements in php. there would be multiple objects of this class. there is no definite selector through which I can get the value of the anchor tag. Help would be much appreciated. echo '<div id="content">'; echo '<div class="showcase_data">'; echo '<div class="showcase_HEAD">'.$row->title.'</div>'; echo '<div class="showcase_TYPE">'.$row->type.'</div>'; echo '<div class="showcase_date">&nbsp;&nbsp;'.$row->date.'</div>'; echo '<div class="showcase_THUMB" style="float: left;" ></div>'; echo '<div class="showcase_TEXT">'.$row->details.'</div><br/>'; echo '<div class="showcase_URL"><a class="purl" value='.$row->num.'href="'.$row->url.'">PROJECT URL</a></div>'; echo '</div>'; echo '</div>';

  • Problems with listening for an event in child object in Actionscript

    - by Raigomaru
    I have two classes. The first one (the starting class): package { import flash.display.Sprite; import flash.events.KeyboardEvent; import tetris.*; public class TetrisGame extends Sprite { private var _gameWell:Well; public function TetrisGame() { _gameWell = new Well(); addChild(_gameWell); } } } The second: package tetris { import flash.display.Sprite; import flash.events.KeyboardEvent; public class Well extends Sprite { public function Well() { super(); addEventListener(KeyboardEvent.KEY_DOWN, onKeyboard); } private function onKeyboard(event:KeyboardEvent):void { //some code is here } } } But when I press any buttons on my keyboard, the child class Well doesn't have any reaction. What's the problem?

  • Create hyperlink in django template of object that has a space

    - by Ed
    I am trying to create a dynamic hyperlink that depends on a value passed from a function: {% for item in field_list %} <a href={% url index_view %}{{ item }}/> {{ item }} </a> <br> {% endfor %} The problem is that one of the items in field_list is "Hockey Player". The link for some reason is dropping everything after the space, so it creates the hyperlink on the entire "Hockey Player", but the address is http://126.0.0.1:8000/Hockey How can I get it to go to http://126.0.0.1:8000/Hockey Player/ instead?

  • wxpython: Updating a dict or other appropriate data type from wx.lib.sheet.CSheet object

    - by bvmou
    If I have a notebook with three spreadsheet widgets, what is the best way to have changes to the spreadsheet update a dictionary (or maybe an sqlite file?). Do all wx grid objects come with a built in dictionary related to the SetNumberRows and SetNumberCols? Basically I am looking for guidance on how to work with the user-input data from a spreadsheet widget, as in this example adapted from the tutorial on python.org: class ExSheet(wx.lib.sheet.CSheet): def __init__(self, parent): sheet.CSheet.__init__(self, parent) self.SetLabelBackgroundColour('#CCFF66') self.SetNumberRows(50) self.SetNumberCols(50) class Notebook(wx.Frame): def __init__(self, parent, id, title): wx.Frame.__init__(self, parent, id, title) nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM) self.sheet1 = ExSheet(nb) self.sheet2 = ExSheet(nb) self.sheet3 = ExSheet(nb) nb.AddPage(self.sheet1, "Sheet1") nb.AddPage(self.sheet2, "Sheet2") nb.AddPage(self.sheet3, "Sheet3") self.sheet1.SetFocus() self.StatusBar()

  • Memorystream and Large Object Heap

    - by Flo
    I have to transfer large files between computers on via unreliable connections using WCF. Because I want to be able to resume the file and I don't want to be limited in my filesize by WCF, I am chunking the files into 1MB pieces. These "chunk" are transported as stream. Which works quite nice, so far. My steps are: open filestream read chunk from file into byet[] and create memorystream transfer chunk back to 2. until the whole file is sent My problem is in step 2. I assume that when I create a memory stream from a byte array, it will end up on the LOH and ultimately cause an outofmemory exception. I could not actually create this error, maybe I am wrong in my assumption. Now, I don't want to send the byte[] in the message, as WCF will tell me the array size is too big. I can change the max allowed array size and/or the size of my chunk, but I hope there is another solution. My actual question(s): Will my current solution create objects on the LOH and will that cause me problem? Is there a better way to solve this? Btw.: On the receiving side I simple read smaller chunks from the arriving stream and write them directly into the file, so no large byte arrays involved.

  • Object-oriented GUI development in python

    - by ptabatt
    Hey guys, new programmer here. I have an assignment for class and I'm stuck... What I need to do is a create a GUI that gives someone a basic arithmetic problem in one box, asks the person to answer it, evaluates it, and tells you if you're right or wrong... Basically, what I have is this: [code] class Lesson(Frame): def init (self, parent=None): Frame.init(self, parent) self.pack() Lesson.make_widgets(self) def make_widgets(self): Label(self, text="").pack(side=TOP) ent = Entry(self) self.a = randrange(1,10) self.b = randrange(1,10) self.expr = choice(["+","-"]) ent.insert(END, str(self.a) + str(self.expr) + str(self.a)) [/code] I've broken this down into many little steps and basically, what I'm trying to do right now is insert a default random expression into the first entry widget. When I run this code, I just get a blank Label. Why is that? How can I put a something like "7+7" into the box? If you absolutely need background to the problem, it's question #3 on this link. http://reed.cs.depaul.edu/lperkovic/csc242/homeworks/Homework8.html -Thanks for all help in advance.

  • How can you query for an object using one of its properties' id

    - by James Smith
    I have two entities, say, House and People, where multiple people can live in one house. It's a unidirectional link where each Person has a field for which House they belong to, so the Person table has a column named house_id. I need to be able to return all the Person objects who belong to a certain House, but I only have the id of the house. This can be done like this: House house = houseDAO.findById(houseId); List people = session.createCriteria(Person.class).add(Restrictions.eq("house", house)).list(); But since I don't need the house, that's adding an unnecessary query. I've tried to do: session.createCriteria(Person.class).add(Restrictions.eq("house_id", houseId)).list(); But that doesn't work because house_id is not a property, it's a database column. I could just add an sql restriction, but is there a hibernate way of doing this?

  • Parsing plain text to some structured object

    - by Jeriho
    I am working on parsing plain text and converting it to key-value pairs. For example, plain text: some_uninteresting_thing key1 valueA, valueB, valueC key2 valueD key3 valueE valueF key4 valueG(valueH, valueI) key5 some_uninteresting_thing valueJ some_uninteresting_thing key6 some_uninteresting_thing (key6 shouldn't be mapped because has no appropriate values) As you can see plain text is lenient. What java library can handle this? If no such library exist, any suggestions on algorithm to do this.
