• Winforms MVP with Castle Windsor - DI for subforms?

  - by Paul Kirby

  I'm building a winforms app utilizing passive-view MVP and Castle Windsor as an IoC container. I'm still a little new to dependency injection and MVP, so I'm looking for some clarity... I have a main form which contains a number of user controls, and also will bring up other dialogs (ex. Login, options, etc) as needed. My first question is...should I use constructor injection to get the presenters for these other views into the main view, or should I go back to a Service Locator-type pattern? (which I've been told is a big nono!) Or something else? Second question...the user controls need to communicate back to the main form when they are "completed" (definition of that state varies based on the control). Is there a standard way of hooking these up? I was thinking perhaps just wiring up events between the main presenter and the child presenters, but I'm not sure if this is proper thinking. I'd appreciate any help, it seems that the combination of MVP and IoC in winforms isn't exactly well-documented.

• Ubuntu 10.04 with HD flash

  - by Brad Robertson

  Just noticed that 10.04 is out. My media server has been packed away for a few months but I might dust if off and give 10.04 a shot but I thought I'd see if anyone has any success stories with HD flash in either Chrome or Firefox. I'm currently running Ubuntu 9.10 and it was a large enough pain to get VDPAU working with my Zotac Ion-ITX-C board (eventually found an mplayer PPA that had it compiled in) From reading the 10.04 docs it looks like this is standard now, but I'm wondering about streaming HD, from, say flash or Divx. I've never been able to get HD flash to play without it being extremely choppy, and I chalk this up to the lack of hardware assisted decoding like VDPAU (a guess). My board certainly isn't a competitor in CPU power or memory, which is why i've needed the HW accelerated decoding for HD vids in the past. Just wondering if anyone has had any success stories playing HD vid online (flash, divx or what have you)

• Can't find instructions how to use Windows 7 drivers on Windows Server 2008 R2

  - by Robert Koritnik

  Windows 7 x64 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 R2 doesn't. Event though it's practically the same OS when it comes to drivers. I know there's a very good reason for this difference. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are usually desktop machines (a bit more powerful though) and would benefit from the whole driver spectrum that Windows 7 offers... Question I know I've been reading on the internet about some trick where you first install Windows 7, than do something to get either all Windows 7 drivers or just those installed, and then install Windows Server 2008 R2 and use those drivers of Windows 7. The thing is I can't find these instructions on the internet any more. If anybody knows where they are please provide the link for the rest of us.

• Setting up Pure-FTPd with admin/user permissions for same directory

  - by modulaaron

  I need to set up 2 Pure-FTPd accounts - ftpuser and ftpadmin. Both will have access to a directory that contains 2 subdirectories - upload and downlaod. The permissions criteria needs to be as follows: ftpuser can upload to /upload but cannot view the contents (blind drop). ftpuser can download from /download but cannot write to it. ftpadmin has full read/write permissions to both, including file deletion Currently, the first two are not a problem - disabling /upload read access and /download write access for ftpuser did the job. The problem is that when a file is uploaded by ftpuser, it's permissions are set to 644, meaning that user ftpadmin can only read it (note that all FTP directories are chown'd to ftpuser:ftpadmin). How can I give ftpadmin the power he so rightfully deserves?

• AutoCompleteTextView displays 'android.database.sqlite.SQLiteCursor@'... after making selection

  - by user244190

  I am using the following code to set the adapter (SimpleCursorAdapter) for an AutoCompleteTextView mComment = (AutoCompleteTextView) findViewById(R.id.comment); Cursor cComments = myAdapter.getDistinctComments(); scaComments = new SimpleCursorAdapter(this,R.layout.auto_complete_item,cComments,new String[] {DBAdapter.KEY_LOG_COMMENT},new int[]{R.id.text1}); mComment.setAdapter(scaComments); auto_complete_item.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/text1" android:layout_width="wrap_content" android:layout_height="wrap_content"/> and thi is the xml for the actual control <AutoCompleteTextView android:id="@+id/comment" android:hint="@string/COMMENT" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="18dp"/> The dropdown appears to work correctly, and shows a list of items. When I make a selection from the list I get a sqlite object ('android.database.sqlite.SQLiteCursor@'... ) in the textview. Anyone know what would cause this, or how to resolve this? thanks Ok I am able to hook into the OnItemClick event, but the TextView.setText() portion of the AutoCompleteTextView widget is updated after this point. The OnItemSelected() event never gets fired, and the onNothingSelected() event gets fired when the dropdown items are first displayed. mComment.setOnItemClickListener( new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub SimpleCursorAdapter sca = (SimpleCursorAdapter) arg0.getAdapter(); String str = getSpinnerSelectedValue(sca,arg2,"comment"); TextView txt = (TextView) arg1; txt.setText(str); Toast.makeText(ctx, "onItemClick", Toast.LENGTH_SHORT).show(); } }); mComment.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Toast.makeText(ctx, "onItemSelected", Toast.LENGTH_SHORT).show(); } @Override public void onNothingSelected(AdapterView<?> arg0) { // TODO Auto-generated method stub Toast.makeText(ctx, "onNothingSelected", Toast.LENGTH_SHORT).show(); } }); Anyone alse have any ideas on how to override the updating of the TextView? thanks patrick

• AlertDialog in if-stetement doesn't show()

  - by Steffen Kern

  I have the following code: public void button_login(View view) { // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); // Preserve EditText values. EditText ET_username = (EditText) findViewById(R.id.username); EditText ET_password = (EditText) findViewById(R.id.password); String str_username = ET_username.toString(); String str_password = ET_password.toString(); // Intercept missing username and password. if(str_username.length() == 0) { builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); } } I have an activity that includes the two EditText-Views and a button. When I click the button the shown method will be called. My problem: The AlertDialog doesnt show up! When I put the create and show at beginning like this: // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); // Preserve EditText values. EditText ET_username = (EditText) findViewById(R.id.username); EditText ET_password = (EditText) findViewById(R.id.password); String str_username = ET_username.toString(); String str_password = ET_password.toString(); // Intercept missing username and password. if(str_username.length() == 0) { } } Then the Dialog shows up. Any ideas why the dialog doesnt show up in the first place? Greetz, Steffen

• Why is my Android app camera preview running out of memory on my AVD?

  - by Bryan

  I have yet to try this on an actual device, but expect similar results. Anyway, long story short, whenever I run my app on the emulator, it crashes due to an out of memory exception. My code really is essentially the same as the camera preview API demo from google, which runs perfectly fine. The only file in the app (that I created/use) is as below- package berbst.musicReader; import java.io.IOException; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; /********************************* * Music Reader v.0001 * Still VERY under construction. * @author Bryan * *********************************/ public class MusicReader extends Activity { private MainScreen main; @Override //Begin activity public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); main = new MainScreen(this); setContentView(main); } class MainScreen extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder sHolder; Camera cam; MainScreen(Context context) { super(context); //Set up SurfaceHolder sHolder = getHolder(); sHolder.addCallback(this); sHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(SurfaceHolder holder) { // Open the camera and start viewing cam = Camera.open(); try { cam.setPreviewDisplay(holder); } catch (IOException exception) { cam.release(); cam = null; } } public void surfaceDestroyed(SurfaceHolder holder) { // Kill all our crap with the surface cam.stopPreview(); cam.release(); cam = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Modify parameters to match size. Camera.Parameters params = cam.getParameters(); params.setPreviewSize(w, h); cam.setParameters(params); cam.startPreview(); } } }

• Computer starts, POSTs normal, no video

  - by Annath

  So, I recently tried to start up an old computer of mine. It would not power on, so I replaced the PSU. When I powered it on, all the fans spun up and the POST beeps indicated a normal startup. The problem was there was no video output. Every couple of minutes, I hear the post code again. I think it is restarting after POST, but without video I have no idea why. Does anyone have an idea as to why this is happening, and how to fix it? EDIT: The video card is a PCI-e card. There is no integrated graphics on the motherboard. If I remove the video card, the POST indicates a missing card. When I put it back, it goes back to normal, so I know that it recognizes that the card exists.

• Internet Explorer 7 Bugs - incorrect display OR dead links

  - by ClarkeyBoy

  Hi, I recently launched a website I have been developing over the past year - http://Live.heritageartpapers.co.uk/. My dad, who owns the company, had a phone call today saying it doesnt display properly in IE7. Bug #1: The header and footer are both in a div, whereas the content is in a table between the two divs. Reportedly the content (table) sometimes (not always, according to IETester) displays below the footer, but the footer still displays where it is supposed to (ie there is a massive gap where the content should fit). Bug #2: When the content does display in the correct place, all the links on the page are dead - click on them and nothing happens. As you can see if you view it in Firefox (the version I am using is 3.6), the links in the left hand menu turn orange on mouseover. However they do not even do this in IE7. Note that they do turn orange and do work if the content is displayed below the footer. I cant see why its happening - according to IETester, the IE7 interpreted source code has all the tags capitalised and many quotes removed (for example for the id attribute on most, if not all, tags) but I doubt this could cause the above bugs, could it? My question is whether anyone has ever seen any of these problems before, and/or has a solution to any of these problems?? I currently do not have the application open, but will post any relevant code in a few minutes. Alternatively just use view source. Many thanks in advance. Regards, Richard Clarke

• Intel D510MO board - 1000Mbit LAN or not?

  - by T.J. Crowder

  The Intel forum seems to be down (signing in fails with connection refused), but perhaps someone here knows the answer. The Intel D510MO product page says that the LAN is 10/100/1000, but when I look at the NM10 chipset it uses, it says it's just 10/100 (and the detailed PDF spec here backs that up pretty definitively). I don't immediately see anything saying the D510MO has a different LAN controller than the NM10's onboard one, and it would seem odd if it did given the purpose of the board (low power, small footprint; integrated). Does this board support 1000Mbit LAN or not? Anyone have direct knowledge of it? Thanks in advance.

• android keylistener losing key taps

  - by miannelle

  I am using a keylistener to get key taps. The problem is that once you tap the delete key, the next key tap is not registering. The key tap after that keeps working. If I tap 2 deletes in a row, they work, just no other keys. They just disappear. I put in a log test before the "if (keycode" section and it shows nothing after the first delete is pressed, unless it is another delete. I am using the following code (Thanks Shawn).: itemPrice.setKeyListener(new CalculatorKeyListener()); itemPrice.setRawInputType(Configuration.KEYBOARD_12KEY); class CalculatorKeyListener extends NumberKeyListener { public int getInputType() { return InputType.TYPE_CLASS_NUMBER; } @Override public boolean onKeyDown(View view, Editable content, int keyCode, KeyEvent event) { if (keyCode >= KeyEvent.KEYCODE_0 && keyCode <= KeyEvent.KEYCODE_9) { digitPressed(keyCode - KeyEvent.KEYCODE_0); } else if (keyCode == KeyEvent.KEYCODE_DEL) { deletePressed(); } return true; } @Override protected char[] getAcceptedChars() { return new char[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; } } With this problem the keylistener provides no value to me. There must be something that I am missing. Thanks,

• adding tabbar to uiview (not tabbarcontroller) to switch views

  - by Pavan

  Hi, i added a Tab bar to my existing view called secondViewController where there are now 4 tab bar items using interface builder. This tab bar will allow the users to switch between views. This is what ive tried to do: If i use a tabbar controller, then a new view pops up and i dont want that. i simply want to be able to add a tab bar as ive done and carry on from there. i dont know how to actually connect it all up and make everything work together. This is what i understand: i have to make my current - secondViewController an tabbardelegate which is what ive done as shown @interface paddedDholViewController : UIViewController <AVAudioPlayerDelegate, UITabBarDelegate> { } then i understand that i have to add tabBar.delegate = self; for me to be able to detect the tabBar:didSelectItem: so i can then implement something like this - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { if ([viewController.tabBarItem.title isEqualToString:@"FIRST"]) { NSLog(@"FIRST"); } else if ([viewController.tabBarItem.title isEqualToString:@"SECOND"]) { NSLog(@"SECOND"); } } to be able to switch between the views The thing is as ive said before i dont know how to implement all of this and how to connect everything up. can someone help me please. Thank you in advance

• How to resize image to fit UITableView cell?

  - by stefanB

  How to fit UIImage into the cell of UITableView, UITableViewCell (?). Do you addSubview to cell or is there a way to resize cell.image or the UIImage before it is assigned to cell.image ? I want to keep the cell size default (whatever it is when you init with zero rectangle) and would like to add icon like pictures to each entry. Images are slightly bigger than the cell size (table row size). I think the code looks like this (from top of my head): UIImage * image = [[UIImage alloc] imageWithName:@"bart.jpg"]; cell = ... dequeue cell in UITableView data source (UITableViewController ...) cell.text = @"bart"; cell.image = image; What do I need to do to resize the image to fit the cell size? I've seen something like: UIImageView * iview = [[UIImageView alloc] initWithImage:image]; iview.frame = CGRectMake(...); // or something similar [cell.contentView addSubview:iview] The above will add image to cell and I can calculate the size to fit it, however: I'm not sure if there is a better way, isn't it too much overhead to add UIImageView just to resize the cell.image ? Now my label (cell.text) needs to be moved as it is obscured by image, I've seen a solution where you just add the text as a label: Example: UILabel * text = [[UILable alloc] init]; text.text = @"bart"; [cell.contentView addSubview:iview]; [cell.contentView addSubview:label]; // not sure if this will position the text next to the label // edited original example had [cell addSubview:label], maybe that's the problem Could someone point me in correct direction? EDIT: Doh [cell.contentview addSubview:view] not [cell addSubview:view] maybe I'm supposed to look at this: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = ...; CGRect frame = cell.contentView.bounds; UILabel *myLabel = [[UILabel alloc] initWithFrame:frame]; myLabel.text = ...; [cell.contentView addSubview:myLabel]; [myLabel release]; }

• How to make the start menu finds a program based on a custom keyword?

  - by Pierre-Alain Vigeant

  I am searching for a way to type a keyword in the start menu Search programs and files field and that it will return the application that match the keyword. An example will better explain this: Suppose that I want to start the powershell. Currently what I can type in the search field is power and the first item that appear is the 64bits powershell shortcut. Now suppose that I'd like ps to return powershell as the first item of the search list. Currently, typing ps return all files with the .ps extension, alongs with a control panel options about recording steps but not the powershell executable itself. How can I do that?

• CQRS - The query side

  - by mattcodes

  A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

• Replacement Alternative for Dell FY606 in a Poweredge T105

  - by Mike C

  I have recently upgraded my Poweredge T105 server to use a SAS 6/ir RAID controller. Unfortunately, I did not realize at the time that adding the card would cause the BIOS to complain about a missing hard drive fan. This warning requires that a user press F1 to continue, which is disastrous in a server environment. I have searched all over found that the specific part I need is a Dell FY606 fan. However, I have yet to find a suitable retailer that covers this part. I have contacted Dell and they do not have this part in stock. Are there any alternative models of a fan that I could use in place of an FY606? Seems like a pretty straightforward part, just a fan that connects to a 4-pin power connector on the motherboard.

• dell E6500 laptop will not hibernate/standby

  I am using a Dell E6500 laptop with windows XP on it, it was originally tagged/installed with Windows Vista. My issue is, when I close the lid, it will not either Hibernate or Standby. If I close the lid with either of these options, I then have to startup from scratch, and anything I had open is not open. I just want to close the lid, have it keep what I have running, not use power util I open the lid again and start it up (with the stuff still open I had open of course). Suggestions?

• How do I keep a CALayer, sublayer of a CATiledLayer, from changing it's scale after a zoom ?

  - by David

  I have a CATiledLayer that is used to display a PDF page (this CATiledLayer is the layer type of my UIView which is a subview of a UIScrollView). I want to add overlay markers on this page. So I add a sublayer to my CATiledLayer. This sublayer again hosts the different marker's layers and acts as a grouping layer. So graphically, I have: (keep in mind that I have multiple markers which are CALayers also, this is ascii art after all) pdf page (CATiledLayer) ---------------------- | CALayer | | +---------+ | | | +----+ | | | | |mker| | | | | +----+ | | | +---------+ | | | ---------------------- I have set up the canonical drawLayer:inContext: in my view for drawing the pdf. When I zoom to have more detail, the pdf gets rendered correctly, but the markers get scaled. No matter what I do to the bounds of the CALayer, my markers always become bigger and appear jagged. I would like to have the markers always the same size, as when they were initialized and first shown when the view was drawn. Is this possible ? or am I using a wrong approach ? Should I do special drawing for my contained CALayer in the drawLAyer:inContext: message ? As you see, there are things that I am missing to resolve my problem. Thank you for any help you provide.

• How do I encapsulate form/post/validation[/redirect] in ViewUserControl in ASP.Net MVC 2

  - by paul

  What I am trying to achieve: encapsulate a Login (or any) Form to be reused across site post to self when Login/validation fails, show original page with Validation Summary (some might argue to just post to Login Page and show Validation Summary there; if what I'm trying to achieve isn't possible, I will just go that route) when Login succeeds, redirect to /App/Home/Index also, want to: stick to PRG principles avoid ajax keep Login Form (UserController.Login()) as encapsulated as possible; avoid having to implement HomeController.Login() since the Login Form might appear elsewhere All but the redirect works. My approach thus far has been: Home/Index includes Login Form: <%Html.RenderAction("Login","User");%> User/Login ViewUserControl<UserLoginViewModel> includes: <%=Html.ValidationSummary("") % using(Html.BeginForm()){} includes hidden form field "userlogin"="1" public class UserController : BaseController { ... [AcceptPostWhenFieldExists(FieldName = "userlogin")] public ActionResult Login(UserLoginViewModel model, FormCollection form){ if (ModelState.IsValid) { if(checkUserCredentials()) { setUserCredentials() return this.RedirectToAction<Areas.App.Controllers.HomeController>(x = x.Index()); } else { return View(); } } ... } Works great when: ModelState or User Credentials fail -- return View() does yield to Home/Index and displays appropriate validation summary. (I have a Register Form on the same page, using the same structure. Each form's validation summary only shows when that form is submitted.) Fails when: ModelState and User Credentials valid -- RedirectToAction<>() gives following error: "Child actions are not allowed to perform redirect actions." It seems like in the Classic ASP days, this would've been solved with Response.Buffer=True. Is there an equivalent setting or workaround now? Btw, running: ASP.Net 4, MVC 2, VS 2010, Dev/Debugging Web Server I hope all of that makes sense. So, what are my options? Or where am I going wrong in my approach? tia!

• ASP.NET MVC 1 and 2 on Mono 2.4 with Fluent NHibernate

  - by SztupY

  Hi! I'd like to create an application using ASP.NET MVC, that should run under mono 2.4 (compiling will be done on a Windows box). Has anyone getting luck with this? Here is what I've already tried: ASP.NET MVC on mono without any persistence model support, and using nhaml as the view engine S#aml architecture, which is a quite good framework imho, but it depends too much on stuff, that are not working good under mono (like windsor) The first part worked fine, I didn't encounter any major problems. But I couldn't get the second part working. It seems it's dependency on Castle.Windsor breaks the whole mono support (but there might be other parts too). Therefore I decided to create an alternative framework, that borrows some of the ideas of s#arp-architecture, but designed to be working under mono (and if I'm able to do this I'll release it for the community of course). The controller and view part is working fine (not much magic here though, they have been always working), but I have some questions before I start job on the persistence part: What NHibernate versions are working under mono? I've heard 1.2 is working fine. Does 2.0.1/2.1 beta work under mono? Does Fluent.NHibernate and NHibernate.Linq work under mono? (for the latter it seems it needs some dependcies that aren't avaialable in mono) Are there any good alternatives for persistence support to NHibernate under mono? Alternative questions: Are there any frameworks that have mono+persistence+asp.net mvc support already or am I the first one to think about this? If you have already done this: what are your opinions on stability/usability? Thanks for the answers EDIT: Updated the framework to support ASP.NET MVC 2: http://shaml.sztupy.hu/

• Does any know fix/cause of USB drives that lose connection

  - by Burch Kealey

  I have been having significant problems trying to copy files to a USB drive (G0-Flex 1.5 tb) No matter what I use to try to copy the files (python code, Windows copy and paste or Drobo Copy utility) I ultimately get a failure. The failure is always some indication that the device is not ready or able to be written to. I am pretty sure the problem is that the drive is losing its connection. I have done everything I can find so far including setting the USB Root hub to never turn off the power, I updated some usb drivers etc. I have found references to this problem primarily with Win7-64 bit. I have also had USB connection problems with other devices- we kept losing a connection to our Bravo Disc Publisher when we went to Win7 and finally bought a newer model and have not had problems since. Any pointers about diagnosing and or understanding the problem would be appreciated.

• Django custom managers - how do I return only objects created by the logged-in user?

  - by Tom Tom

  I want to overwrite the custom objects model manager to only return objects a specific user created. Admin users should still return all objects using the objects model manager. Now I have found an approach that could work. They propose to create your own middleware looking like this: #### myproject/middleware/threadlocals.py try: from threading import local except ImportError: # Python 2.3 compatibility from django.utils._threading_local import local _thread_locals = local() def get_current_user(): return getattr(_thread_locals, 'user', None) class ThreadLocals(object): """Middleware that gets various objects from the request object and saves them in thread local storage.""" def process_request(self, request): _thread_locals.user = getattr(request, 'user', None) #### end And in the Custom manager you could call the get_current_user() method to return only objects a specific user created. class UserContactManager(models.Manager): def get_query_set(self): return super(UserContactManager, self).get_query_set().filter(creator=get_current_user()) Is this a good approach to this use-case? Will this work? Or is this like "using a sledgehammer to crack a nut" ? ;-) Just using: Contact.objects.filter(created_by= user) in each view doesn`t look very neat to me. EDIT Do not use this middleware approach !!! use the approach stated by Jack M. below After a while of testing this approach behaved pretty strange and with this approach you mix up a global-state with a current request. Use the approach presented below. It is really easy and no need to hack around with the middleware. create a custom manager in your model with a function that expects the current user or any other user as an input. #in your models.py class HourRecordManager(models.Manager): def for_user(self, user): return self.get_query_set().filter(created_by=user) class HourRecord(models.Model): #Managers objects = HourRecordManager() #in vour view you can call the manager like this and get returned only the objects from the currently logged-in user. hr_set = HourRecord.objects.for_user(request.user)

• Drawing a PDF Right-Side-Up in CGContext

  - by Carter Allen

  I'm overriding the drawRect: method in a custom UIView, and I'm doing some custom drawing. All was going well, until I needed to draw a PDF resource (a vector glyph, to be precise) into the context. First I retrieve the PDF from a file: NSURL *pdfURL = [NSURL fileURLWithPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"CardKit.bundle/A.pdf"]]; CGPDFDocumentRef pdfDoc = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfDoc, 1); Then I create a box with the same dimensions as the loaded PDF: CGRect box = CGPDFPageGetBoxRect(pdfPage, kCGPDFArtBox); Then I save my graphics state, so that I don't screw anything up: CGContextSaveGState(context); And then I perform a scale+translate of the CTM, theoretically flipping the whole context: CGContextScaleCTM(context, 1.0, -1.0); CGContextTranslateCTM(context, 0.0, rect.size.height); I then scale the PDF so that it fits into the view properly: CGContextScaleCTM(context, rect.size.width/box.size.width, rect.size.height/box.size.height); And finally, I draw the PDF and restore the graphics state: CGContextDrawPDFPage(context, pdfPage); CGContextRestoreGState(context); The issue is that there is nothing visible drawn. All this code should theoretically draw the PDF glyph into the view, right? If I remove the scale+translate used to flip the context, it draws perfectly: it just draws upside-down. Any ideas?
