  • How to right click and play audio folder on Windows Media Player 12

    - by Mehper C. Palavuzlar
    It's always been hard for me to add a music folder with subfolders to Windows Media Player's playlist. I double click a file in the folder (or click on WMP shortcut), WMP opens, and I drag the other files or folders manually to the playlist. Isn't there an option to add a right-click context menu item that can automatically add all audio contents in a folder (with subfolders) to WMP playlist?

  • Adding group + items in Windows Explorer's pop-up menu?

    - by OverTheRainbow
    An application I use regularly is command-line based, and I would like to add the most used commands in the Windows Explorer's context menu that pops up when right-clicking on a file or folder. From what I read, a lot of programs in that menu are COM applications. Is there an easier way to add commands to the menu, as an alternative to opening a DOS box and typing commands? Ideally, it should work for XP, Vista, and 7.

  • LoadFromContext was detected

    - by Alhambra Eidos
    HI all misters When I try Debug my project (unit tests) i get the following error: LoadFromContext was detected Message: The assembly named 'Microsoft.VisualStudio.QualityTools.Common' was loaded from 'file:///C:/Program Files/Microsoft Visual Studio 8/Common7/IDE/PrivateAssemblies/Microsoft.VisualStudio.QualityTools.Common.DLL' using the LoadFrom context. The use of this context can result in unexpected behavior for serialization, casting and dependency resolution. In almost all cases, it is recommended that the LoadFrom context be avoided. This can be done by installing assemblies in the Global Assembly Cache or in the ApplicationBase directory and using Assembly.Load when explicitly loading assemblies. It's nightmare for me...!!! I am using VS 2008 profession, XP sp2 Any suggestions , please ?? Thanks.

  • WPF - Redrawing a Context Menu when Items change?

    - by Rachel
    I have a ItemsControl in a ScrollViewer, and when the items exceed the width of the ScrollViewer they are put into a ContextMenu and shown as a DropDown instead. My problem is that when the Context Menu is first loaded, it saves the saves the size of the Menu and does not redraw when more commands get added/removed. For example, a panel has 3 commands. 1 is visible and 2 are in the Menu. Viewing the menu shows the 2 commands and draws the control, but then if you resize the panel so 2 are visible and only 1 command is in the menu, it doesn't redraw the menu to eliminate that second menu item. Or even worse, if you shrink the panel so that no commands are shown and all 3 are in the Menu, it will only show the top 2. Here's my code: <Button Click="DropDownMenu_Click" ContextMenuOpening="DropDownMenu_ContextMenuOpening"> <Button.ContextMenu> <ContextMenu ItemsSource="{Binding Path=MenuCommands}" Placement="Bottom"> <ContextMenu.Resources> <Style TargetType="{x:Type MenuItem}"> <Setter Property="Command" Value="{Binding Path=Command}" /> <Setter Property="Visibility" Value="{Binding Path=IsVisible, Converter={StaticResource ReverseBooleanToVisibilityConverter}}"/> </Style> </ContextMenu.Resources> <ContextMenu.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Path=DisplayName}" /> </DataTemplate> </ContextMenu.ItemTemplate> </ContextMenu> </Button.ContextMenu> </Button> Code Behind: void DropDownMenu_ContextMenuOpening(object sender, ContextMenuEventArgs e) { Button b = sender as Button; b.ContextMenu.IsOpen = false; e.Handled = true; } private void DropDownMenu_Click(object sender, RoutedEventArgs e) { Button b = sender as Button; ContextMenu cMenu = b.ContextMenu; if (cMenu != null) { cMenu.PlacementTarget = b; cMenu.Placement = System.Windows.Controls.Primitives.PlacementMode.Bottom; } } I have tried using InvalidateVisual and passing an empty delegate on Render to try and force a redraw, however neither works. I'm using .Net 4.0.

  • How do uppercase and lowercase letters differ by only one bit?

    - by Vibhakar SInha
    I have found one example in Data and Communication Networking book written by Behrouza Forouzan regarding upper- and lowercase letters which differ by only one bit in the 7 bit code. For example, character A is 1000001 (0x41) and character a is 1100001 (0x61).The difference is in bit 6, which is 0 in uppercase letters and 1 in lowercase letters. If we know the code for one case, we can easily find the code for the other by adding or subtracting 32 in decimal, or we can just flip the sixth bit. What does all this mean? I have found myself very confused with all these things. Could someone provide examples of how these things really work out?

  • GNU Flex, multiline rule

    - by Simone Margaritelli
    Hi there i have a flex rule inside my lexer definition : operators "[]"|"[]="|"[]<"|".."|"."|".="|"+"|"+="|"-"|"-="|"/"|"/="|"*"|"*="|"%"|"%="|"++"|"--"|"^"|"^="|"~"|"&"|"&="|"|"|"|="|"<<"|"<<="|">>"|"!"|"<"|">"|">="|"<="|"=="|"!="|"&&"|"||"|"~=" Is there any way to split this ruole on more lines to keep it clearer? I tried with \ just like macros but it does not seem to be accepted by flex :( PS: I don't want to split the rule in more sub-rules, but only split its regex in more lines to keep the code clearer.

  • What makes Ometa special?

    - by Brian
    Ometa is "a new object-oriented language for pattern matching." I've encountered pattern matching in languages like Oz tools to parse grammars like Lexx/Yacc or Pyparsing before. Despite looking at example code, reading discussions, and talking to a friend, I still am not able to get a real understanding of what makes Ometa special (or at least, why some people think it is). Any explanation?

  • JSONP context problem

    - by PoweRoy
    I'm using a javascript autocomplete () in a greasemonkey script. On itself it works correctly but I wan't to add JSONP because I want the data from another domain. The code (snippet): function autosuggest(url) { this.suggest_url = url; this.keywords = []; return this.construct(); }; autosuggest.prototype = { construct: function() { return this; }, preSuggest: function() { this.CreateJSONPRequest(this.suggest_url + "foo"); }, CreateJSONPRequest: function(url) { var headID = document.getElementsByTagName("head")[0]; var newScript = document.createElement('script'); newScript.type = 'text/javascript'; newScript.src = url +'&callback=autosuggest.prototype.JSONCallback'; //newScript.async = true; newScript.onload = newScript.onreadystatechange = function() { if (newScript.readyState === "loaded" || newScript.readyState === "complete") { //remove it again newScript.onload = newScript.onreadystatechange = null; if (newScript && newScript.parentNode) { newScript.parentNode.removeChild(newScript); } } } headID.appendChild(newScript); }, JSONCallback: function(data) { if(data) { this.keywords = data; this.suggest(); } }, suggest: function() { //use this.keywords } }; //Add suggestion box to textboxes window.opera.addEventListener('AfterEvent.load', function (e) { var textboxes = document.getElementsByTagName('input'); for (var i = 0; i < textboxes.length; i++) { var tb = textboxes[i]; if (tb.type == 'text') { if (tb.autocomplete == undefined || tb.autocomplete == '' || tb.autocomplete == 'on') { //we handle autosuggestion tb.setAttribute('autocomplete','off'); var obj1 = new autosuggest("http://test.php?q="); } } } }, false); I removed not relevant code. Now when 'preSuggest' is called, it add a script to the header and circumvent the crossdomain problem. Now when the data is received back 'JSONcallback' is called. I can use the data, but when 'Suggest' is I can't use the this.keywords array or this.suggest_url. I think this is because 'JSONcallback' and 'Suggest' are called in a different context. How can I get this working?

  • Parse tree and grammars information

    - by fuzzylogikk
    Do anyone know where to find good online resources with examples how to make grammars and parsetrees? Preferebly introductary materials. Info that is n00b friendly, haven't found anything good with google myself. edit: I'm thinking about theory, not a specific parser software.

  • Running out of memory with UIImage creation on an offscreen Bitmap Context by NSOperation

    - by sigsegv
    I have an app with multiple UIView subclasses that acts as pages for a UIScrollView. UIViews are moved back and forth to provide a seamless experience to the user. Since the content of the views is rather slow to draw, it's rendered on a single shared CGBitmapContext guarded by locks by NSOperation subclasses - executed one at once in an NSOperationQueue - wrapped up in an UIImage and then used by the main thread to update the content of the views. -(void)main { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc]init]; if([self isCancelled]) { return; } if(nil == data) { return; } // Buffer is the shared instance of a CG Bitmap Context wrapper class // data is a dictionary CGImageRef img = [buffer imageCreateWithData:data]; UIImage * image = [[UIImage alloc]initWithCGImage:img]; CGImageRelease(img); if([self isCancelled]) { [image release]; return; } NSDictionary * result = [[NSDictionary alloc]initWithObjectsAndKeys:image,@"image",id,@"id",nil]; // target is the instance of the UIView subclass that will use // the image [target performSelectorOnMainThread:@selector(updateContentWithData:) withObject:result waitUntilDone:NO]; [result release]; [image release]; [pool release]; } The updateContentWithData: of the UIView subclass performed on the main thread is just as simple -(void)updateContentWithData:(NSDictionary *)someData { NSDictionary * data = [someData retain]; if([[data valueForKey:@"id"]isEqualToString:[self pendingRequestId]]) { UIImage * image = [data valueForKey:@"image"]; [self setCurrentImage:image]; [self setNeedsDisplay]; } // If the image has not been retained, it should be released together // with the dictionary retaining it [data release]; } The drawLayer:inContext: method of the subclass will just get the CGImage from the UIImage and use it to update the backing layer or part of it. No retain or release is involved in the process. The problem is that after a while I run out of memory. The number of the UIViews is static. CGImageRef and UIImage are created, retained and released correctly (or so it seems to me). Instruments does not show any leaks, just the free memory available dip constantly, rise a few times, and then dip even lower until the application is terminated. The app cycles through about 2-300 of the aforementioned pages before that, but I would expect to have the memory usage reach a more or less stable level of used memory after a bunch of pages have been already skimmed at fast speed or, since the images are up to 3MB in size, deplete way earlier. Any suggestion will be greatly appreciated.

  • Why is this c# snippet legal?

    - by Sir Psycho
    Silly question, but why does the following line compile? int[] i = new int[] {1,}; As you can see, I haven't entered in the second element and left a comma there. Still compiles even though you would expect it not to.

  • Data Quality Check - SQL Server

    - by user319384
    I am trying to find a good mechanism where I can check whether the data being entered by a group of people is grammatically correct, has correct spellings, etc, etc. I also would like to compute words per minute and accuracy. Is there any process to do this so that I do not have to re-invent the wheel? Thanks in advance.

  • The Definition of Regular Languages

    - by AraK
    Good Day, I have tried, and burned my brain to understand the definition of Regular Languages in Discrete Mathematics and its Applications(Rosen) without reaching the goal of understanding why the definition is like that in this book. On page(789), I am rephrasing the definition: Type 3 grammars are defined as: w1 --> w2 Where w1 is a non-terminal, and w2 is of the form: w2 = aB w2 = a Where B is a non-terminal, and a is a terminal. A special case is when w1 is the starting symbol and w2 is lambda(the empty string): w1 = S S --> lambda Two questions I couldn't find an answer for. First, Why can't w2 be of the form Ba. Second, Why lambda is only allowed for the starting symbol only. The book states that, regular languages are equivalent to Finite State Automaton, and we can easily see that a we can build FSA for both cases. I took a look at other resources, and these restrictions don't exist in these resources. Thanks,

  • Theory of computation - Using the pumping lemma for CFLs

    - by Tony
    I'm reviewing my notes for my course on theory of computation and I'm having trouble understanding how to complete a certain proof. Here is the question: A = {0^n 1^m 0^n | n>=1, m>=1} Prove that A is not regular. It's pretty obvious that the pumping lemma has to be used for this. So, we have |vy| = 1 |vxy| <= p (p being the pumping length, = 1) uv^ixy^iz exists in A for all i = 0 Trying to think of the correct string to choose seems a bit iffy for this. I was thinking 0^p 1^q 0^p, but I don't know if I can obscurely make a q, and since there is no bound on u, this could make things unruly.. So, how would one go about this?

  • rhino embedding

    - by neheh
    Anyone understands the rhino javascript Contexts? I cannot find any useful documentation about it. My main problem is the Context.exit() (really should be cx.exit()) which from what I understand exits the context associated with the current thread? Does that mean I need to keep track of what which thread does? main thread: Context cx; cx.evaluateReader( ... ) // load some function start thread 2 thread 2: Object o= scope.get("methodname", scope); ((Function)o).call( ... ) I do not plan on doing multithreading but what if the different setups comes from different threads?

  • How do I best do balanced quoting with Perl's Regexp::Grammars?

    - by Evan Carroll
    Using Damian Conway's Regexp::Grammars, I'm trying to match different balanced quoting ('foo', "foo", but not 'foo") mechanisms -- such as parens, quotes, double quotes, and double dollars. This is the code I'm currently using. <token: pair> \'<literal>\'|\"<literal>\"|\$\$<literal>\$\$ <token: literal> [\S]+ This generally works fine and allows me to say something like: <rule: quote> QUOTE <.as>? <pair> My question is how do I reform the output, to exclude the needles notation for the pair token? { '' => 'QUOTE AS \',\'', 'quote' => { '' => 'QUOTE AS \',\'', 'pair' => { 'literal' => ',', '' => '\',\'' } } }, Here, there is obviously no desire to have pair in between, quote, and the literal value of it. Is there a better way to match 'foo', "foo", and $$foo$$, and maybe sometimes ( foo ) without each time creating a needless pair token? Can I preprocess-out that token or fold it into the above? Or, write a better construct entirely that eliminates the need for it?

  • Uppercase and lowercase urls in PHP

    - by Arjun
    I have created folders in my root example: http://www.zipholidays.co.uk/Cuba or http://www.zipholidays.co.uk/Florida When I type http://www.zipholidays.co.uk/cuba (Cube in lowercase), it shows page not found. I'm using Apache server. People are linking to pages with lowercase, uppercase, mixed case - whatever. What do I do to make the pages case insensitive?

  • Apache rewrite_mod: RewriteRule path and query string

    - by 1ace
    I currently have a website with a standard web interface on index.php, and I made an iPhone-friendly version in iphone.php. Both pages handle the same arguments. It works fine when I manually go to .../iphone.php, but I'd like to rewrite anything on .../path/ and .../path/index.php to iphone.php if %{HTTP_USER_AGENT} contains mobile, and optionally add the query string (not sure if/when I'd need to add it). So far, this is what I have in my .../path/.htaccess: RewriteEngine On RewriteCond %{HTTP_USER_AGENT} ^.+mobile.+$ [NC] RewriteRule index.php?(.*) iphone.php?$1 [L] RewriteRule index.php iphone.php [L] The problems are, it matches index.php in any subfolder, and it won't match .../path/?args… Special thanks to anyone who can correct/simplify/optimize anything =)
