  • Calling up DockPanel-Suite's "AutoHidden" DockContent programmatically

    - by Lockszmith
    I am having trouble causing an 'autohide' dock to appear programmatically. Couldn't find any answer around the net, though the following SO Question suggested that .Show() should have done the trick I've tried this on the latest NuGet version of the code. My test code is below. Anyone know how to do it? or what I'm doing wrong? My test Code Create a simple Visual Studio Windows Form application, and replace the main form's source file content with this code: using System; using System.Windows.Forms; using dps = WeifenLuo.WinFormsUI.Docking; namespace testDockPanel { public partial class Form1 : Form { private dps.DockPanel dockPanel; private dps.DockContent dc; private Control innerCtrl; public Form1() { InitializeComponent(); dockPanel = new dps.DockPanel(); dockPanel.Dock = DockStyle.Fill; dockPanel.DocumentStyle = dps.DocumentStyle.DockingWindow; toolStripContainer1.ContentPanel.Controls.Add(dockPanel); dc = new dps.DockContent(); dc.DockPanel = dockPanel; dc.DockState = dps.DockState.DockRightAutoHide; innerCtrl = new WebBrowser() { Dock = DockStyle.Fill }; dc.Controls.Add( innerCtrl ); // This SHOULD show the autohide-dock, but NOTHING happens. dc.Show(); } } }

  • Python progression path - From apprentice to guru

    - by Morlock
    Hi all, I've been learning, working, and playing with Python for a year and a half now. As a biologist slowly making the turn to bio-informatics, this language has been a the very core of all the major contributions I have made in the lab. (bash and R scripts have helped some too. My C++ capabilities are very not functional yet). I more or less fell in love with the way Python permits me to express beautiful solutions and also with the semantics of the language that allows such a natural flow from thoughts to workable code. What I would like to know from you is your answer to a kind of question I have seldom seen in this or other forums. Let me sum up what I do NOT want to ask first ;) I don't want to know how to QUICKLY learn Python Nor do I want to find out the best way to get acquainted with the language Finally, I don't want to know a 'one trick that does it all' approach. What I do want to know your opinion about, is: What are the steps YOU would recommend to a Python journeyman, from apprenticeship to guru status (feel free to stop wherever your expertise dictates it), in order that one IMPROVES CONSTANTLY, becoming a better and better Python coder, one step at a time. The kind of answers I would enjoy (but feel free to surprise the readership :P ), is formatted more or less like this: Read this (eg: python tutorial), pay attention to that kind of details Code for so manytime/problems/lines of code Then, read this (eg: this or that book), but this time, pay attention to this Tackle a few real-life problems Then, proceed to reading Y. Be sure to grasp these concepts Code for X time Come back to such and such basics or move further to... (you get the point :) This process depicts an iterative Learn/Code cycle, and I really care about knowing your opinion on what exactly one should pay attention to, at various stages, in order to progress CONSTANTLY (with due efforts, of course). If you come from a specific field of expertise, discuss the path you see as appropriate in this field. Thanks a lot for sharing your opinions and good Python coding!

  • Preventing Flex application caching in browser (multiple modules)

    - by Simon_Weaver
    I have a Flex application with multiple modules. When I redeploy the application I was finding that modules (which are deployed as separate swf files) were being cached in the browser and the new versions weren't being loaded. So i tried the age old trick of adding ?version=xxx to all the modules when they are loaded. The value xxx is a global parameter which is actually stored in the host html page: var moduleSection:ModuleLoaderSection; moduleSection = new ModuleLoaderSection(); moduleSection.visible = false; moduleSection.moduleName = moduleName + "?version=" + MySite.masterVersion; In addition I needed to add ?version=xxx to the main .swf that was being loaded. Since this is done by HTML I had to do this by modifying my AC_OETags.js file as below : function AC_FL_RunContent(){ var ret = AC_GetArgs ( arguments, ".swf?mv=" + getMasterVersion(), "movie", "clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" , "application/x-shockwave-flash" ); AC_Generateobj(ret.objAttrs, ret.params, ret.embedAttrs); } This is all fine and works great. I just have a hard time believing that Adobe doesn't already have a way to handle this. Given that Flex is being targeted to design modular applications for business I find it especially surprising. What do other people do? I need to make sure my application reloads correctly even if someone has once per session selected for their 'browser cache checking policy'.

  • Ruby on Rails: Using XML Builder Partials

    - by randombits
    Partials in XML builder are proving to be non-trivial. After some initial Google searching, I found the following to work, although it's not 100% xml.foo do xml.id(foo.id) xml.created_at(foo.created_at) xml.last_updated(foo.updated_at) foo.bars.each do |bar| xml << render(:partial => 'bar/_bar', :locals => { :bar => bar }) end end this will do the trick, except the XML output is not properly indented. the output looks something similar to: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> The <bar> element should align underneath the <last_updated> element, it is a child of <foo> like this: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> Works great if I copy the content from bar/_bar.xml.builder into the template, but then things just aren't DRY.

  • OpenSSL.NET can't export private key with null Cipher

    - by Nick
    I've recently discovered OpenSSL.NET and it's a pretty sweet little wrapper. I'm trying to execute the following code: public static void DoSomething(byte[] buf) { OpenSSL.Core.BIO input = new OpenSSL.Core.BIO(buf); OpenSSL.X509.X509Certificate b = OpenSSL.X509.X509Certificate.FromPKCS12(input, "passphrase"); OpenSSL.Core.BIO outs = OpenSSL.Core.BIO.MemoryBuffer(false); b.PrivateKey.WritePrivateKey(outs, OpenSSL.Crypto.Cipher.Null, "passphrase"); outs.SetClose(OpenSSL.Core.BIO.CloseOption.Close); Console.WriteLine(outs.ReadString()); } Problem comes at the "b.PrivateKey.WritePrivateKey(.." line. I want to write the private key out without any encryption. According to spec, if I use a Null cipher type this should do the trick, but it never works, regardless of the cert I use in buf. Here's the exception: error:0D0A706C:asn1 encoding routines:PKCS5_pbe2_set:cipher has no object identifier error:2307D00D:PKCS12 routines:PKCS8_encrypt:ASN1 lib I know this part works fine because if I specify any other cipher type, it exports the private key without fail. Anyone have any suggestions?

  • Remove file from git repository (history)

    - by Devenv
    (solved, see bottom of the question body) Looking for this for a long time now, what I have till now is: http://dound.com/2009/04/git-forever-remove-files-or-folders-from-history/ and http://progit.org/book/ch9-7.html Pretty much the same method, but both of them leave objects in pack files... Stuck. What I tried: git filter-branch --index-filter 'git rm --cached --ignore-unmatch file_name' rm -Rf .git/refs/original rm -Rf .git/logs/ git gc Still have files in the pack, and this is how I know it: git verify-pack -v .git/objects/pack/pack-3f8c0...bb.idx | sort -k 3 -n | tail -3 And this: git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch file_name" HEAD rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune The same... Tried git clone trick, it removed some of the files (~3000 of them) but the largest files are still there... I have some large legacy files in the repository, ~200M, and I really don't want them there... And I don't want to reset the repository to 0 :( SOLUTION: This is the shortest way to get rid of the files: check .git/packed-refs - my problem was that I had there a refs/remotes/origin/master line for a remote repository, delete it, otherwise git won't remove those files (optional) git verify-pack -v .git/objects/pack/#{pack-name}.idx | sort -k 3 -n | tail -5 - to check for the largest files (optional) git rev-list --objects --all | grep a0d770a97ff0fac0be1d777b32cc67fe69eb9a98 - to check what files those are git filter-branch --index-filter 'git rm --cached --ignore-unmatch file_names' - to remove the file from all revisions rm -rf .git/refs/original/ - to remove git's backup git reflog expire --all --expire='0 days' - to expire all the loose objects (optional) git fsck --full --unreachable - to check if there are any loose objects git repack -A -d - repacking the pack git prune - to finally remove those objects

  • problem using getline with a unicode file

    - by hamishmcn
    UPDATE: Thank you to @Potatoswatter and @Jonathan Leffler for comments - rather embarrassingly I was caught out by the debugger tool tip not showing the value of a wstring correctly - however it still isn't quite working for me and I have updated the question below: If I have a small multibyte file I want to read into a string I use the following trick - I use getline with a delimeter of '\0' e.g. std::string contents_utf8; std::ifstream inf1("utf8.txt"); getline(inf1, contents_utf8, '\0'); This reads in the entire file including newlines. However if I try to do the same thing with a wide character file it doesn't work - my wstring only reads to the the first line. std::wstring contents_wide; std::wifstream inf2(L"ucs2-be.txt"); getline( inf2, contents_wide, wchar_t(0) ); //doesn't work For example my if unicode file contains the chars A and B seperated by CRLF, the hex looks like this: FE FF 00 41 00 0D 00 0A 00 42 Based on the fact that with a multibyte file getline with '\0' reads the entire file I believed that getline( inf2, contents_wide, wchar_t(0) ) should read in the entire unicode file. However it doesn't - with the example above my wide string would contain the following two wchar_ts: FF FF (If I remove the wchar_t(0) it reads in the first line as expected (ie FE FF 00 41 00 0D 00) Why doesn't wchar_t(0) work as a delimiting wchar_t of "00 00"? Thank you

  • How to make a UITextField move up when keyboard is present

    - by philfreo
    EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

  • Handling 2 buttons submit Actions in a single View/Form - ASP.NET MVC 2 RTM

    - by Leniel Macaferi
    I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request. Note: the most intriguing part is that the upload was working and all of sudden it stopped working. I've seen that some people are having the same problem with FileUpload tasks in which the Request.Files is always Empty. I think it's empty because you need a post to the server. Isn't it?

  • Wpf Mvvm ComboBox

    - by 2Fast4YouBR
    Hi All, I am new in the Wpf world, so I created a couple of views and all of them have at least one ComboBox, as I am using the MvvM pattern, I get my self re-typing all the time the same line of codes to fill the Combo and to get the SelectedItem (creating properties, privates for fill and other to get). Is there some kind of framework that can improve this part ? or hack/trick ??? as I see too much repetitive code... maybe I am doing something wrong, take a look: XAML: <ComboBox name= "cbDepartments" DisplayMemberPath="DepartmentName" SelectedValuePath ="PrimaryKey" ItemsSource="{Binding Path=Departments}" SelectedItem="{Binding Path=DefaultBranch,Mode=TwoWay}" > ViewModel: private Department defaultBranch; public Department DefaultBranch { get { return this.defaultBranch; } set { if (this.defaultBranch != value) { this.defaultBranch = value; this.OnPropertyChanged("DefaultBranch"); this.saveChangeCommand.RaiseCanExecuteChanged(); this.UserMessage = string.Empty; } } } private ObservableCollection<Department> departments; public ObservableCollection<Department> Departments { get { return this.departments; } set { if (this. departments!= value) { this. departments = value; this.OnPropertyChanged("Departments"); } } }

  • Getting Android SDK WebView and TabWidget to play nice

    - by jdandrea
    I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

  • ASP.NET MVC 4 async child action

    - by ShadowChaser
    I have an ASP.NET MVC 4 application targeting .NET 4.5. One of our child actions makes a call out to a web service using HttpClient. Since we're blocking on IO waiting for the HttpClient response, it makes a great deal of sense to convert the code to the async/await pattern. However, when MVC 4 attempts to execute the child action, we get the following error message: HttpServerUtility.Execute blocked while waiting for an asynchronous operation to complete. At first glance, it appears as though MVC 4 does not support async/await within a child action. The only remaining option is to run using synchronous code and force a "Wait" on the async task. As we all know, touching .Result or .Wait() on an async task in an ASP.NET context will cause an immediate deadlock. My async logic is wrapped in a class library, so I can't use the "await blah.ConfigureAwait(false)" trick. Remember, tagging "async" on the child action and using await causes an error, and that prevents me from configuring the await. I'm painted into a corner at this point. Is there any way to consume async methods in an MVC 4 child action? Seems like a flat out bug with no workarounds.

  • Make Iframe to fit 100% of container's remaining height

    - by Darkthread
    I want to design a web page with a banner and a iframe. I hope the iframe can fill all the remaining page height and be resized automatically as browser resizing. Is it possible to get it done without writing Javascript code, only with CSS? I tried set height:100% on iframe, the result is quite close but the iframe tried to fill the whole page height, including the 30px height of banner div element, so I got unneccessary vertical scrollbar. It's not perfect. Update Notes: Excute me for not describing the question well, I tried CSS margin, padding attribute on DIV to occupy the whole remining height of a web page successfully, but the trick didn't work on iframe. <body> <div style="width:100%; height:30px; background-color:#cccccc;">Banner</div> <iframe src="http: //www.google.com.tw" style="width:100%; height:100%;"></iframe> </body> Any idea is appreciated.

  • How to avoid XCode framework weak-linking problems?

    - by Frank R.
    Hi, I'm building an application that takes advantage of Mac OS X 10.6-only technologies, but without giving up backwards compatibility to 10.5 Leopard. The way I do this is by setting the 10.6 SDK as the base SDK, weak-linking all frameworks and setting the deployment target to 10.5 as described in: http://developer.apple.com/mac/library/DOCUMENTATION/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html This works fine; before making a call that is Snow Leopard-only I need to check that the selector or indeed the class actually exist. Or I can just check the OS version before making the call. The problem is that this is incredibly fragile. If I make a single call that is 10.6 only I blow Leopard-compatibility. So using even the normal code code completion feature can be dangerous. My question: is there any way of checking which calls are not defined on 10.5 before doing a release build? Some kind of static analysis, or even just a trick (a target set the other SDK?) would do. I obviously should test on a Leopard machine before releasing anything, but even so I can't possibly go through all paths of the program before every release. Any advice would be appreciated. Best regards, Frank

  • When do married programmers find time to work?

    - by dave-keiture
    Hi people, Maybe my problem is unique (though I don't believe so), and probably I should go with it to the psychologist, but sinse I get married (~year ago) I feel that I don't have enough time to work anymore. For years I've been working at my day job doing regular stuff, and at nights I've been committing to the opensource projects, freelancing and self-educating. Now, I can't work at home at all, because once I start working, my wife either says that there're more important thing to do (walk out the dog, buy something in a grocery, etc.) or that I don't pay anough attention to her.. As a workaround, I've started getting up at 3-4AM in the morning to do the things I was usually doing nightly before. After a month of such schedule I feel myself totally crushed. So... 2 questions: Do you have the same problems, or I'm just a <..., who should say goodbye to programming, and start doing "really important things"? If you have the same problems, when do you find time to work? Maybe you know any cool lifehack or trick to spend at least some tome for doing the thing you like :) Best regards.

  • Manditory read-only fields in django

    - by jamida
    I'm writing a test "grade book" application. The models.py file is shown below. class Student(models.Model): name = models.CharField(max_length=50) parent = models.CharField(max_length=50) def __unicode__(self): return self.name class Grade(models.Model): studentId = models.ForeignKey(Student) finalGrade = models.CharField(max_length=3) I'd like to be able to change the final grade for several students in a modelformset but for now I'm just trying one student at a time. I'm also trying to create a form for it that shows the student name as a field that can not be changed, the only thing that can be changed here is the finalGrade. So I used this trick to make the studentId read-only. class GradeROForm(ModelForm): studentId = forms.ModelChoiceField(queryset=Student.objects.all()) def __init__(self, *args, **kwargs): super(GradeROForm,self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.id: self.fields['studentId'].widget.attrs['disabled']='disabled' def clean_studentId(self): instance = getattr(self,'instance',None) if instance: return instance.studentId else: return self.cleaned_data.get('studentId',None) class Meta: model=Grade And here is my view: def modifyGrade(request,student): student = Student.objects.get(name=student) mygrade = Grade.objects.get(studentId=student) if request.method == "POST": myform = GradeROForm(data=request.POST, instance=mygrade) if myform.is_valid(): grade = myform.save() info = "successfully updated %s" % grade.studentId else: myform=GradeROForm(instance=mygrade) return render_to_response('grades/modifyGrade.html',locals()) This displays the form like I expect, but when I hit "submit" I get a form validation error for the student field telling me this field is required. I'm guessing that, since the field is "disabled", the value is not being reported in the POST and for reasons unknown to me the instance isn't being used in its place. I'm a new Django/Python programmer, but quite experienced in other languages. I can't believe I've stumbled upon such a difficult to solve problem in my first significant django app. I figure I must be missing something. Any ideas?

  • Workflow Foundation (WF) -- Why does Visual Studio's designer not use my custom ActivityDesignerThem

    - by stakx
    Problem: I am trying to customize a custom Workflow Foundation activity (called CustomActivity) so that it will display with a specific background color. What I've got so far: First, I'm defining a custom ActivityDesignerTheme as follows: public class CustomActivityTheme : ActivityDesignerTheme { public CustomActivityTheme(WorkflowTheme theme) : base(theme) { this.BackColorStart = Color.FromArgb(0xff, 0xf4, 0xf4, 0xf4); this.BackColorEnd = Color.FromArgb(0xff, 0xc0, 0xc0, 0xc0); this.BackgroundStyle = LinearGradientMode.Horizontal; } } Then, I am applying this theme to a custom ActivityDesigner (apparently the theme must be applied to a designer, and not to an activity): [ActivityDesignerTheme(typeof(CustomActivityTheme))] public class CustomActivityDesigner : SequentialActivityDesigner { ... } Ultimately, I am applying the custom designer to my custom Activity: [Designer(typeof(CustomActivityDesigner))] public partial class CustomActivity : SequenceActivity { ... } Now, according to some code examples that I've seen, this should do the trick. However, when I include an instance of my CustomActivity in a workflow, my custom theme is not applied and it is displayed in the Visual Studio Designer as any standard activity would (white background etc.). I tried re-compiling and even re-starting Visual Studio a couple of times, just to make sure the used assembly is up-to-date, but to no avail. My question: What am I missing? Why does Visual Studio's Workflow Designer not respect the CustomActivityTheme when it displays a CustomActivity?

  • Verifying regular expression for malware removal

    - by Legend
    Unfortunately, one of my web servers was compromised recently. I have two questions. Is there a way I can scan the downloaded directory for backdoors? Is there anything I can do to ensure that at least known vulnerabilities do not exist anymore? Secondly, the malware put up the following in all index.* files on my webserver: <script>/*GNU GPL*/ try{window.onload = function(){var Hva23p3hnyirlpv7 = document.createElement('script');Hva23p3hnyirlpv7.setAttribute('type', 'text/javascript');Hva23p3hnyirlpv7.setAttribute('id', 'myscript1');Hva23p3hnyirlpv7.setAttribute('src',.... CODE DELETED FOR SAFETY.... );}} catch(e) {}</script> Obviously, this snippet seems to download some rogue file onto the user's machine. I downloaded an entire backup of the web server and am currently trying to remove this snippet from all file. For this I am doing: find ./ -name "index.*" -exec sed -i 's/<script>\/\*GNU GPL\*.*Hva23p3hnyirlpv7.*<\/script>//g' {} \; Just wanted to verify if this does the trick. I verified it with a few files but I want to be sure that this doesn't delete some valid code. Anyone suggests any other modifications?

  • Would OpenID or OAuth work for authorization/authentication on a distributed web service?

    - by David Eyk
    We're in the early stages of designing a RESTful/resource-oriented web service API for a computational lingustics application. Because many of the resources we plan to serve are rights-encumbered, a key design decision has been to specify the platform so that each resource provider can expose their own web service that complies with the API spec. This way, the rights owner maintains control over their content (and thus the ability to throttle or deny access at will) and a direct relationship with the consumer, while still being able to participate in in the collaborative network. At the same time, to simplify the job of writing a client for this service, we want to allow a client access to the distributed service through one end-point, with the server handling content negotiation and retrieval from the appropriate providers. Right now, we're at an impasse on authentication/authorization schemes. One of our number has argued for the (technical) simplicity of a central authentication registry, but others are concerned about the organizational complexity of such a scheme. It seems to me, based on an albeit limited understanding of the technologies, that a combination of OpenID and OAuth would do the trick, with a client authenticating with the end-point via OpenID, and the server taking action on the user's behalf with the various content providers using OAuth. I've only ever seen implementations (e.g. stackoverflow, twitter, etc.) where a human was present to intervene, and I still need to do more research on these technologies. Would a scheme like this work for an automated web service, or would it make the client too difficult to implement and operate?

  • Creating a UIImage from a rotated UIImageView...

    - by Magic Bullet Dave
    I have a UIImageView with an image in it. I have rotated the image prior to display by setting the transform property of the UIImageView to CGAffineTransformMakeRotation(angle) where angle is the angle in radians. I want to be able to create another UIImage that corresponds to the rotated version that I can see in my view. I am almost there, by rotating the image context I get a rotated image: - (UIImage *) rotatedImageFromImageView: (UIImageView *) imageView { UIImage *rotatedImage; // Get image width, height of the bonuding rectangle CGRect boundingRect = [self getBoundingRectAfterRotation: imageView.bounds byAngle:angle]; // Create a graphics context the size of the boundinf rectangle UIGraphicsBeginImageContext(boundingRect.size); CGContextRef context = UIGraphicsGetCurrentContext(); // Rotate and translate the context CGAffineTransform ourTransform = CGAffineTransformIdentity; ourTransform = CGAffineTransformConcat(ourTransform, CGAffineTransformMakeRotation(angle)); CGContextConcatCTM(context, ourTransform); // Draw the image into the context CGContextDrawImage(context, CGRectMake(0, 0, imageView.image.size.width, imageView.image.size.height), imageView.image.CGImage); // Get an image from the context rotatedImage = [UIImage imageWithCGImage: CGBitmapContextCreateImage(context)]; // Clean up UIGraphicsEndImageContext(); return rotatedImage; } However the image is not rotated about its centre. I have tried all kinds of transforms concatenated with my rotate to get it to rotate around the centre but to no avail. Am I missing a trick? Is this even possible since I am rotating the context not the image? Getting desperate to make this work now, so any help would be appreciated. Dave

  • Integrating a Custom Compiler with the Visual Studio IDE

    - by M.A. Hanin
    Background: I want to create a custom VB compiler, extending the "original" compiler, to handle my custom compile-time attributes. Question: after I've created my custom compiler and I've got an executable file capable of compiling VB code via the standard command-line interface, how do I integrate this compiler with the Visual Studio IDE? (such that pressing "compile" or "build" will make use of my compiler instead of the default compiler). EDIT: (Correct me if i'm wrong) From the reactions here, I see this question is a bit shocking, so I shall further explain my needs and background: .NET provides us with a great mechanism called Attributes. As far as I understand, making attributes apply their intended behavior upon the attributed element (assembly, module, class, method, etc.) - attributes must be reflected upon. So the real trick here is reflecting and applying behavior at the right spot. Lets take Serialization for example: We decorate a class with the Serializable attribute. We then pass an instance of the class to the formatter's Serialize method. The formatter reflects upon the instance, checking if it has the Serializable attribute, and acting accordingly. Now, if we examine the Synchronization, Flags, Obsolete and CLSCompliant attributes, then the real question is: who reflects upon them? At least in some cases, it has to be the compiler (and/or IDE). Therefore, it seems that if I wish to create custom attributes that change an element's behavior regardless of any specific consumer, i must extend the compiler to reflect upon them at compilation. Of course, these are not my personal insights: the book "Applied .NET Attributes" provides a complete example of creating a custom attribute and a custom C# compiler to reflect upon that attribute at compilation (the example is used to implement "java-style checked exceptions").

  • Draw on screen border in Commodore 64

    - by Stefano Borini
    Ok. I hope it does not get closed because I have this curiosity since 25 years and I would love to understand the trick. In the commodore 64 the border was not addressable by the 6569 VIC. All you could do was to draw pixels in the central area, the one where the cursor moved. The border was always uniform, although you could change its color with poke 53280,color if i remember correctly. Nevertheless I clearly remember games intros where the border was featured with graphics, like it was fully addressable. I tried to understand how it worked but never got to the point. legends say it was a clever use of sprites, which could, under some circumstances, be drawn on the border, but I don't know if it's an urban legend. edit: just read this from one of the provided links Sprites were multiplexed across vertical raster lines (over 8 sprites, sometimes up to 120 sprites). Until the Group Crest released Krestage 3 in May 2007 there was the common perception that no more than 8 sprites could appear at one raster line, but assigning new Y coordinates made it reappear further down the screen. This is evil.... you beat the raster and reposition the sprite before it gets there...
