  • App will not launch from drawer after phone is removed from car dock

    - by BigFwoosh
    I am creating a replacement Car Home app for Android 2.0+ devices. The app needs to launch when the phone is inserted into the car dock, as well as terminate when it is removed from the dock. It also needs to be able to be launched from the app drawer. I'm having a problem right now where once the phone is inserted and removed from the dock, I can no longer launch the app from the app drawer because every time I launch the app my BroadcastReceiver picks up a DOCK_EVENT action for some reason. I created a test project that only registers my BroadcastReceiver, and the same thing happens. Here's the code for the BroadcastReceiver: public class CarDockBroadcastReceiver extends BroadcastReceiver { /** * @see android.content.BroadcastReceiver#onReceive(Context,Intent) */ @Override public void onReceive(Context context, Intent intent) { // TODO Put your code here if(intent.getExtras().containsKey("android.intent.extra.DOCK_STATE")){ int state = intent.getExtras().getInt("android.intent.extra.DOCK_STATE",1); if(state == 0){ Log.i("Dock", "Removed from dock!"); ((Activity)context).finish(); } } } } My main Activity is as follows: public class MainActivity extends Activity { /** Called when the activity is first created. */ CarDockBroadcastReceiver receiver; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); IntentFilter filter = new IntentFilter("android.intent.action.DOCK_EVENT"); receiver = new CarDockBroadcastReceiver(); registerReceiver(receiver, filter); } @Override protected void onDestroy() { // TODO Auto-generated method stub unregisterReceiver(receiver); super.onDestroy(); } } The main Activity has an intent filter for action.MAIN, category.LAUNCHER, category.DEFAULT, and category.CAR_DOCK. Any ideas on why this is happening?

  • C# String.Replace with a start/index (Added my (slow) implementation)

    - by Chris T
    I'd like an efficient method that would work something like this EDIT: Sorry I didn't put what I'd tried before. I updated the example now. // Method signature, Only replaces first instance or how many are specified in max public int MyReplace(ref string source,string org, string replace, int start, int max) { int ret = 0; int len = replace.Length; int olen = org.Length; for(int i = 0; i < max; i++) { // Find the next instance of the search string int x = source.IndexOf(org, ret + olen); if(x > ret) ret = x; else break; // Insert the replacement source = source.Insert(x, replace); // And remove the original source = source.Remove(x + len, olen); // removes original string } return ret; } string source = "The cat can fly but only if he is the cat in the hat"; int i = MyReplace(ref source,"cat", "giraffe", 8, 1); // Results in the string "The cat can fly but only if he is the giraffe in the hat" // i contains the index of the first letter of "giraffe" in the new string The only reason I'm asking is because my implementation I'd imagine getting slow with 1,000s of replaces.

  • How do I correctly detect presence of FLTK using SCONS?

    - by James Morris
    I'm trying to build an application I've downloaded which uses the SCONS "make replacement" and the Fast Light Tool Kit Gui. The SConstruct code to detect the presence of fltk is: guienv = Environment(CPPFLAGS = '') guiconf = Configure(guienv) if not guiconf.CheckLibWithHeader('lo', 'lo/lo.h','c'): print 'Did not find liblo for OSC, exiting!' Exit(1) if not guiconf.CheckLibWithHeader('fltk', 'FL/Fl.H','c++'): print 'Did not find FLTK for the gui, exiting!' Exit(1) Unfortunately, on my (Gentoo Linux) system, and many others (Linux distributions) this can be quite troublesome if the package manager allows the simultaneous install of FLTK-1 and FLTK-2. Being Idealistic, I attempted to modify the SConstruct file to use fltk-config --cflags and fltk-config --ldflags (or fltk-config --libs might be better than ldflags) by adding them like so: guienv.Append(CPPPATH = os.popen('fltk-config --cflags').read()) guienv.Append(LIBPATH = os.popen('fltk-config --ldflags').read()) But this causes the test for liblo to fail! Looking in config.log shows how it failed: scons: Configure: Checking for C library lo... gcc -o .sconf_temp/conftest_4.o -c "-I/usr/include/fltk-1.1 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT" gcc: no input files scons: Configure: no How should this really be done?

  • Custom view transition in OpenGL ES

    - by melfar
    I'm trying to create a custom transition, to serve as a replacement for a default transition you would get here, for example: [self.navigationController pushViewController:someController animated:YES]; I have prepared an OpenGL-based view that performs an effect on some static texture mapped to a plane (let's say it's a copy of the flip effect in Core Animation). What I don't know how to do is: grab current view content and make a texture out of it (I remember seeing a function that does just that, but can't find it) how to do the same for the view that is currently offscreen and is going to replace current view are there some APIs I can hook to in order to make my transition class as native as possible (make it a kind of Core Animation effect)? Any thoughts or links are greatly appreciated! UPDATE Jeffrey Forbes's answer works great as a solution to capture the content of a view. What I haven't figured out yet is how to capture the content of the view I want to transition to, which should be invisible until the transition is done. Also, which method should I use to present the OpenGL view? For demonstration purposes I used pushViewController. That affects the navbar, though, which I actually want to go one item back, with animation, check this vid for explanation: http://vimeo.com/4649397. Another option would be to go with presentViewController, but that shows fullscreen. Do you think maybe creating another window (or view?) could be useful?

  • Why are virtual methods considered early bound?

    - by AspOnMyNet
    One definition of binding is that it is the act of replacing function names with memory addresses. a) Thus I assume early binding means function calls are replaced with memory addresses during compilation process, while with late binding this replacement happens during runtime? b) Why are virtual methods also considered early bound (thus the target method is found at compile time, and code is created that will call this method)? As far as I know, with virtual methods the call to actual method is resolved only during runtime and not compile time?! thanx EDIT: 1) A a=new A(); a.M(); As far as I know, it is not known at compile time where on the heap (thus at which memory address ) will instance a be created during runtime. Now, with early binding the function calls are replaced with memory addresses during compilation process. But how can compiler replace function call with memory address, if it doesn’t know where on the heap will object a be created during runtime ( here I’m assuming the address of method a.M will also be at same memory location as a )? 2) v-table calls are neither early nor late bound. Instead there's an offset into a table of function pointers. The offset is fixed at compile time, but which table the function pointer is chosen from depends on the runtime type of the object (the object contains a hidden pointer to its v-table), so the final function address is found at runtime. But assuming the object of type T is created via reflection ( thus app doesn’t even know of existence of type T ), then how can at compile time exist an entry point for that type of object?

  • Handling file uploads with JavaScript and Google Gears, is there a better solution?

    - by gnarf
    So - I've been using this method of file uploading for a bit, but it seems that Google Gears has poor support for the newer browsers that implement the HTML5 specs. I've heard the word deprecated floating around a few channels, so I'm looking for a replacement that can accomplish the following tasks, and support the new browsers. I can always fall back to gears / standard file POST's but these following items make my process much simpler: Users MUST to be able to select multiple files for uploading in the dialog. I MUST be able to receive status updates on the transmission of a file. (progress bars) I would like to be able to use PUT requests instead of POST I would like to be able to easily attach these events to existing HTML elements using JavaScript. I.E. the File Selection should be triggered on a <button> click. I would like to be able to control response/request parameters easily using JavaScript. I'm not sure if the new HTML5 browsers have support for the desktop/request objects gears uses, or if there is a flash uploader that has these features that I am missing in my google searches. An example of uploading code using gears: // select some files: var desktop = google.gears.factory.create('beta.desktop'); desktop.openFiles(selectFilesCallback); function selectFilesCallback(files) { $.each(files,function(k,file) { // this code actually goes through a queue, and creates some status bars // but it is unimportant to show here... sendFile(file); }); } function sendFile(file) { google.gears.factory.create('beta.httprequest'); request.open('PUT', upl.url); request.setRequestHeader('filename', file.name); request.upload.onprogress = function(e) { // gives me % status updates... allows e.loaded/e.total }; request.onreadystatechange = function() { if (request.readyState == 4) { // completed the upload! } }; request.send(file.blob); return request; } Edit: apparently flash isn't capable of using PUT requests, so I have changed it to a "like" instead of a "must".

  • Javascript string replace with calculations

    - by Chris
    Is there a way to resolve mathematical expressions in strings in javascript? For example, suppose I want to produce the string "Tom has 2 apples, Lucy has 3 apples. Together they have 5 apples" but I want to be able to substitute in the variables. I can do this with a string replacement: string = "Tom has X apples, Lucy has Y apples. Together they have Z apples"; string2 = string.replace(/X/, '2').replace(/Y/, '3').replace(/Z/, '5'); However, it would be better if, instead of having a variable Z, I could use X+Y. Now, I could also do a string replace for X+Y and replace it with the correct value, but that would become messy when trying to deal with all the possible in-string calculations I might want to do. I suppose I'm looking for a way to achieve this: string = "Something [X], something [Y]. Something [(X+Y^2)/5X]"; And for the [_] parts to be understood as expressions to be resolved before substituting back into the string. Thanks for your help.

  • What's the difference between an option type and a nullable type?

    - by Peter Olson
    In F# mantra there seems to be a visceral avoidance of null, Nullable<T> and its ilk. In exchange, we are supposed to instead use option types. To be honest, I don't really see the difference. My understanding of the F# option type is that it allows you to specify a type which can contain any of its normal values, or None. For example, an Option<int> allows all of the values that an int can have, in addition to None. My understanding of the C# nullable types is that it allows you to specify a type which can contain any of its normal values, or null. For example, a Nullable<int> a.k.a int? allows all of the values that an int can have, in addition to null. What's the difference? Do some vocabulary replacement with Nullable and Option, null and None, and you basically have the same thing. What's all the fuss over null about?

  • How to Use XSLT to Replace Coordinate Separator With List of Tuples?

    - by kuloch
    I have a space-separated list of coordinate tuples. Each tuple consists of a space-separated list of 2-dimensional coordinates. E.g. "1.1 2.8 1.2 2.9" represents a line from POINT(1.1 2.8) to POINT(1.2 2.9). I need this to instead be "1.1,2.8 1.2,2.9". How would I use XSLT to perform the replacement of space-to-comma between pairs of numbers? I have the "string(gml:LinearRing/gml:posList)". This is being used on a Java Web Service that spits out GML 3.1.1 features with geometries. The service supports optional KML output, by using XSLT to transform the GML document into a KML document (at least, the chunks deemed "important"). I am locked into XSLT 1.0, so regex from XSLT 2.0 is not an option. I am aware that GML uses lat/lon while KML uses lon/lat. That's being handled before XSLT, though it would be nice to have that also done with XSLT.

  • How to replace characters in a java String?

    - by ManBugra
    I like to replace a certain set of characters of a string with a corresponding replacement character in an efficent way. For example: String sourceCharacters = "šdccŠÐCCžŽ"; String targetCharacters = "sdccSDCCzZ"; String result = replaceChars("Gracišce", sourceCharacters , targetCharacters ); Assert.equals(result,"Gracisce") == true; Is there are more efficient way than to use the replaceAll method of the String class? My first idea was: final String s = "Gracišce"; String sourceCharacters = "šdccŠÐCCžŽ"; String targetCharacters = "sdccSDCCzZ"; // preparation final char[] sourceString = s.toCharArray(); final char result[] = new char[sourceString.length]; final char[] targetCharactersArray = targetCharacters.toCharArray(); // main work for(int i=0,l=sourceString.length;i<l;++i) { final int pos = sourceCharacters.indexOf(sourceString[i]); result[i] = pos!=-1 ? targetCharactersArray[pos] : sourceString[i]; } // result String resultString = new String(result); Any ideas? Btw, the UTF-8 characters are causing the trouble, with US_ASCII it works fine.

  • Alternative to 'Dispatch for ASP' deployment plug-in?

    - by Django Reinhardt
    Hi there, we've recently stumbled across the excellent Dispatch for ASP deployment plug in. It looks great apart from one thing: It doesn't work with Visual Studio 2010, at least for us, anyway. (It's supposed to work fine.) (Yes, we've tried everything: We've managed to get Dispatch working for another FTP site, but not the main one we regularly deploy to. We have managed to connect to our main site through FileZilla FTP, so the site itself is configured correctly. All settings have been triple checked, but the software still throws up weird errors (always to do with its internal libraries).) So does anyone know of any other comparable FTP-based, deployment plug-ins for Visual Studio? Here's what Dispatch does (and so any suggested replacement must do): Monitor any altered files in the project. When a file is changed, it's added to a list of files to be deployed. To deploy these files to the live site, all we need to do is click "Upload" and the plugin will connect via FTP to our live site and upload all the files. We can filter out any filenames we don't want to be monitored/uploaded (e.g. .cs or web.config or /Images/, etc.) I think that's all the features that we need. Thanks for any suggestions!

  • prevent escaping special characters on textnode(JS-HTML)

    - by UnLoCo
    Hello i followed this snippet http://bytes.com/topic/javascript/answers/504399-get-all-text-nodes var xPathResult = document.evaluate( './/text()[normalize-space(.) != ""]', document.body, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null ); for (var i = 0, l = xPathResult.snapshotLength; i < l; i++) { var textNode = xPathResult.snapshotItem(i); textNode.data = textNode.data.replace(/somePattern/g, 'replacement'); } i want to replace certain patterns like for example |12| with a corresponding emoticon ! but when i do textNode.data.replace("|12|",'<.img src="favicon.ico"/>'); for example the text show is ..<.img src="favicon.ico"/>.. as i inspect the html i find that <.img src="favicon.ico"/> became escaped to &lt;img src="favicon.ico"/&gt; is it possible to prevent this and to let the image show ?? Thank You Note: added extra point here &lt;.img src="favicon.ico"/&gt; in purpose

  • Visual Studio identical token highlighting

    - by dsteinweg
    I coded a Mancala game in Java for a college class this past spring, and I used the Eclipse IDE to write it. One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. Notepad++, my preferred Notepad replacement, also does this. Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurance of the word in the document. A screenshot of these features in action: After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features? Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

  • Conditionally overriding a system method via categories in Objective-C?

    - by adib
    Hi Is there a way to provide a method implementation (that bears the exact same name of a method defined by the framework) only when the method isn't already defined in the system? For example method [NSSomeClass someMethod:] exists only in Mac OS X 10.6 and if my app runs in 10.5, I will provide that method's definition in a category. But when the app runs in 10.6, I want the OS-provided method to run. Background: I'm creating an app targeted for both 10.5 and 10.6. The problem is that I recently realized that method +[NSSortDescriptor sortDescriptorWithKey:ascending:] only exists in 10.6 and my code is already littered by that method call. I could provide a default implementation for it (since this time it's not too difficult to implement it myself), but I want the "native" one to be called whenever my app runs on 10.6. Furthermore if I encounter similar problems in the future (with more difficult-to-implement-myself methods), I might not be able to get away with providing a one-liner replacement. This question vaguely similar to Override a method via ObjC Category and call the default implementation? but the difference is that I want to provide implementations only when the system doesn't already has one. Thanks.

  • How can I have a VBA macro perform a Search/Replace in formulas across an entire workbook?

    - by richardtallent
    I distribute an Excel workbook to a number of users, and they are supposed to have a particular macro file pre-installed in their XLSTART folder. If they don't have the macro installed correctly, and they send the workbook back to me, any formulas depending on it include the full path of the macro, e.g.: 'C:\Documents and Settings\richard.tallent\Application Data\ Microsoft\Excel\XLSTART\pcs.xls'!MyMacroFunction() I want to create a quick macro I can use to remove the improper path from every formula in the workbook. I've successfully retrieved the special folder using GetSpecialFolder (an external function that is working just fine), but the Replace call itself shown below throws an "Application-defined or object-defined error". Public Sub FixBrokenMacroFormulas() Dim badpath As String badpath = "'" & GetSpecialFolder(AppDataFolder) & "\Microsoft\Excel\XLSTART\mymacro.xls'!" Dim Sheet As Worksheet For Each Sheet In ActiveWorkbook.Sheets Call Sheet.Activate Call Sheet.Select(True) Call Selection.Replace(What:=badpath, Replacement:="", LookIn:=xlFormulas) ''//LookAt:=xlPart, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next End Sub Automating search and replace isn't exactly my forte, what am I doing wrong? I've already commented out some of the parameters that don't seem essential.

  • Unattended Install of SQL Server 2005 Express with LOCAL Server InstanceName

    - by Jeff
    I'm creating an install package using InnoSetup and installing SQL Server 2005 Express. Here's the code below that appears in my RUN section: Filename: "{app}\SQL Server 2005 Express\SQLEXPR.exe" ; Parameters: "-q /norebootchk /qn reboot=ReallySuppress addlocal=all INSTANCENAME=(LOCAL) SCCCHECKLEVEL=IncompatibleComponents:1;MDAC25Version:0 ERRORREPORTING=2 SQLAUTOSTART=1 SAPWD=passwordhere SECURITYMODE=SQL"; WorkingDir: {app}\SQL Server 2005 Express; StatusMsg: Installing Microsoft SQL Server 2005 Express... Please Wait...;Check:SQLVerifyInstall What I'm trying to accomplish is have the SQL Server package install but only have the instance name itself reference the name of the machine name and nothing more. What I'm receiving instead is a named instance instead of local such as MachineName\SQLEXPRESS which is not what I want to receive. I need a local instance instead of a named instance due to the way my code is written to be able to install and talk with the databases in question. I would change it, trust me, were it not the fact that this install package is a replacement to a previous package that used the MSDE installer. I have to be able to support both through code. Any suggestions are welcome but a clear and concise method to get the installer to quietly install using only the machine name is my main goal. Thanks for the help and support!

  • Old dll.config problem !

    - by user313421
    Since 2005 as I googled it's a problem for who needs to read the configuration of an assembly from it's config file "*.dll.config" and Microsoft didn't do anything yet. Story: If you try to read a setting from a class library (plug-in) you fail. Instead the main application domain (EXE which is using the plug-in) config is read and because probably there's not such a config your plug-in will use default setting which is hard-coded when you create it's settings for first time. Any change to .dll.config wouldn't see by your plug-in and you wonder why it's there! If you want to replace it and start searching you may find something like this: http://stackoverflow.com/questions/594298/c-dll-config-file But just some ideas and one line code. A good replacement for built-in config shouldn't read from file system each time we need a config value, so we can store them in memory; Then what if user changes config file ? we need a FileSystemWatcher and we need some design like singleton ... and finally we are at the same point configuration of .NET is except our one's working. It seems MS did everything but forgot why they built the ".dll.config". Since no DLL is gonna execute by itself, they are referenced from other apps (even if used in web) and so why there's such a "*.dll.config" file ? I'm not gonna argue if it's good to have multiple config files or not. It's my design (plug-able components). Finally { After these years, is there any good practice such as a custom setting class to add in each assemly and read from it's own config file ? }

  • Visual Studio crashes consistently on web-related projects

    - by Traveling Tech Guy
    Hi, I have a brand new VS2010 installed on a Win2008R2 machine. I started getting this error when debugging a WCF service project: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." When I started developing a web site a week later, this became consistent - I can't debug it. The stack dump reads: at Microsoft.VisualStudio.WebHost.Host.ProcessRequest(Connection conn) at Microsoft.VisualStudio.WebHost.Server.OnSocketAccept(Object acceptedSocket) at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() I tried searching online, and some recommend turning off the "Suppress JIT Optimizations" in the Debugging options - this dos not seem to make a difference. Clearly the problem is with the built in web server. But am I doing something wrong? Is there something I can do? Or is this a known bug? Thanks for your time, Guy Update 12/31: Today I tried using CassiniDev as a replacement to the original VS2010 WebServer - exact same result. My suspicion is that there's some internal conflict between VS2010, Windows Server 2008R2 and maybe the fact that it's a 64 bit OS. I switched to using IIS as my debug server - and that seems to work, with some annoying side effects. My conclusion: do not use a 64 bit server system as your dev machine. Develop on 32bit - deploy to 64bit. Side conclusion: there are some scenarios Microsoft's QA doesn't test.

  • Why would I use Assembly.LoadFile in lieu of Assembly.LoadFrom?

    - by Cheeso
    It's my impression that Assembly.LoadFrom uses the ApplicationBase and PrivateBinPath. It also my impression that Assembly.LoadFile does not. Why would anyone want to use LoadFile? In other words, if my understanding is correct, why would anyone want to NOT use the ApplicationBase and PrivateBinPath? I'm working with some existing code, which uses LoadFile, and I don't understand why it would do so. LoadFile apparently does not load dependencies from the same directory. The LoadFrom method does load dependencies (From the doc: The load-from context...allows dependencies on that path to be found and loaded because the path information is maintained by the context.) I'd like to convert it from using LoadFile, to use LoadFrom. What is likely to break, if anything, if I replace LoadFile with LoadFrom? Even if it iss benign, it may be that I cannot do the replacement, just based on project schedules. If I cannot replace LoadFile with LoadFrom, is there a way to convince assemblies loaded with LoadFile to load dependencies? Is there a packaging trick I can use (embedded assembly, ILMerge, an AssemblyResolve event, something like that) that can allow an assembly loaded with LoadFile to also load its dependencies?

  • UIButton receives touches at the wrong position after CABasicAnimaton applied

    - by Dmitry
    I need to add an animation to UIButton - simple moving animation. When I do this, the button moves, but the click area of that button remains at old position: UIButton *slideButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [slideButton addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside]; [slideButton setFrame:CGRectMake(50, 50, 50, 50)]; [self.view addSubview:slideButton]; CABasicAnimation *slideAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; [slideAnimation setRemovedOnCompletion:NO]; [slideAnimation setDuration:1]; [slideAnimation setFillMode:kCAFillModeBoth]; [slideAnimation setAutoreverses:NO]; slideAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(50, 50)]; slideAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(100, 100)]; [slideButton.layer addAnimation:slideAnimation forKey:@"slide"]; I already saw an answer to change the frame of the button at the end of the animation (like here UIButton receives touchEvents at the wrong position after a CABasicAnimaton) But it's not my case because I should give possibility to user to click on the button while it's moving... Also, I can't use another approaches (like NSTimer) as a replacement for CABasicAnimation because I will have a complex path to move the object... Thanks for Your help!

  • template specialization of a auto_ptr<T>

    - by Chris Kaminski
    Maybe I'm overcomplicating things, but then again, I do sort of like clean interfaces. Let's say I want a specialization of auto_ptr for an fstream - I want a default fstream for the generic case, but allow a replacement pointer? tempate <> class auto_ptr<fstream> static fstream myfStream; fstream* ptr; public: auto_ptr() { // set ptr to &myfStream; } reset(fstream* newPtr) { // free old ptr if not the static one. ptr = newPtr }; } Would you consider something different or more elegant? And how would you keep something like the above from propagating outside this particular compilation unit? [The actual template is a boost::scoped_ptr.] EDIT: It's a contrived example. Ignore the fstream - it's about providing a default instance of object for an auto_ptr. I may not want to provide a specialized instance, but would like to keep the auto_ptr semantics for this static default object. class UserClass { public: auto_ptr<fstream> ptr; UserClass() { } } I may not provide an dynamic object at construction time - I still want it to have a meaningful default. Since I'm not looking at ownership-transfer semantics, it really shouldn't matter that my pointer class is pointing to a statically allocated object, no?

  • How to append \line into RTF using RichTextBox control

    - by Steve Sheldon
    When using the Microsoft RichTextBox control it is possible to add new lines like this... richtextbox.AppendText(System.Environment.NewLine); // appends \r\n However, if you now view the generated rtf the \r\n characters are converted to \par not \line How do I insert a \line control code into the generated RTF? What does't work: Token Replacement Hacks like inserting a token at the end of the string and then replacing it after the fact, so something like this: string text = "my text"; text = text.Replace("||" "|"); // replace any '|' chars with a double '||' so they aren't confused in the output. text = text.Replace("\r\n", "_|0|_"); // replace \r\n with a placeholder of |0| richtextbox.AppendText(text); string rtf = richtextbox.Rtf; rtf.Replace("_|0|_", "\\line"); // replace placeholder with \line rtf.Replace("||", "|"); // set back any || chars to | This almost worked, it breaks down if you have to support right to left text as the right to left control sequence always ends up in the middle of the placeholder. Sending Key Messages public void AppendNewLine() { Keys[] keys = new Keys[] {Keys.Shift, Keys.Return}; SendKeys(keys); } private void SendKeys(Keys[] keys) { foreach(Keys key in keys) { SendKeyDown(key); } } private void SendKeyDown(Keys key) { user32.SendMessage(this.Handle, Messages.WM_KEYDOWN, (int)key, 0); } private void SendKeyUp(Keys key) { user32.SendMessage(this.Handle, Messages.WM_KEYUP, (int)key, 0); } This also ends up being converted to a \par Is there a way to post a messaged directly to the msftedit control to insert a control character? I am totally stumped, any ideas guys? Thanks for your help!

    I've created a simple HttpModule and response stream to reformat the rendered output of web pages (see code snippets below). In the HttpModule I set the Response.Filter to my PageStream: m_Application.Context.Response.Filter = new PageStream(m_Application.Context); In the PageStream I overwrite the Write method in order to do my reformatting of the rendered output: public override void Write(byte[] buffer, int offset, int count) { string html = System.Text.Encoding.UTF8.GetString(buffer); //Do some string resplace operations here... byte[] input = System.Text.Encoding.UTF8.GetBytes(html); m_DefaultStream.Write(input, 0, input.Length); } And this work fine when using it on simple HTML pages (.html), but when I use this method on ASPX pages (.aspx), the Write method is called several times, splitting up the reformatting into different steps, and potentially destroying the string replacement operations. How do I solve this? Is there a way to let the ASPX page NOT call Write several times, e.g. by changing its buffer size, or have I chosen the wrong approach entirely, by using this Response.Filter method to manipulate the rendered output?

  • Silverlight 4 ComboBox - Binding to Nullable data (tried TargetNullValue but not working as expected)

    - by Laurence
    (Please note - I am a Silverlight beginner and am looking for the simplest solution here, e.g. that doesn't involve writing/installing a replacement for the ComboBox control!) This is an issue with a Silverlight 4 application that uses the View Model (MVVM) approach. I have a simple form for editing a "Product" object. Product has a CategoryID property which is nullable (int?). A ComboBox is used to view and set the CategoryID - this is bound to an ObservableCollection of Categories. Product also has number of non-nullable properties bound to TextBoxes. I want the user to see "N/A" in the ComboBox for a product with no category, and to be use this "N/A" option to set CategoryID to null. So, I manually added a Category object with CategoryID=0 and CategoryName="N/A" to the collection; then I set TargetNullValue=0 in the SelectedValue Binding of the ComboBox. My thinking was - when the ComboBox SelectedValue was bound to a null CategoryID it would substitute zero, and therefore select the "N/A" option. When editing a Product with a non-null CategoryID, everything works. However when a null CategoryID is found, two problems occur: No option is selected in the ComboBox (its blank) The ComboBox binding seems broken from this point onwards - any Product I subsequently edit (incl. ones with a non-null CategoryID) have nothing selected in the ComboBox (its still populated with all categories - just no selected item). I've seen reports of problem #2 (here, here) but I was under the impression that #1 should have worked. What am I missing to get the "N/A" option to be selected? XAML for ComboBox: <ComboBox x:Name="cboCategory" ItemsSource="{Binding colCategories, Mode=OneWay}" SelectedValuePath="CategoryID" DisplayMemberPath="CategoryName" SelectedValue="{Binding CurrentProduct.CategoryID, Mode=TwoWay, TargetNullValue=0}" Height="24" Width="344"></ComboBox>

  • delete multi-line block of text with internal flag in povray file

    - by Sibo Lin
    I have a pov-ray file, which defines a lot of cylinders and spheres. Sometimes these shapes are defined to have "color@", which makes the povray unrenderable. One solution I've found is to delete the offending cylinders and spheres. So a file that contains this text cylinder { < -0.17623, 0.24511, -0.27947>, < -0.15220, 0.22658, -0.26472>, 0.00716 texture { colorO } } sphere { < -0.00950, 0.00357, 0.00227>, 0.00716 texture { color@ } } cylinder { < -0.00950, 0.00357, 0.00227>, < 0.00327, 0.00169, 0.00108>, 0.00716 texture { color@ } } sphere { < 0.15373, 0.00601, 0.18223>, 0.00716 texture { colorO } } would turn into this text cylinder { < -0.17623, 0.24511, -0.27947>, < -0.15220, 0.22658, -0.26472>, 0.00716 texture { colorO } } sphere { < 0.15373, 0.00601, 0.18223>, 0.00716 texture { colorO } } Is there some way to do this replacement with a shell script? Preferably in tcsh. Thanks!
