• Mass audio encoder

  - by bessman

  I have a few thousand FLAC files which I would like to transcode to OGG Vorbis, but I can't find any suitable tools for the job. To name a few I have tried so far and why they are unsuitable: oggenc is single-threaded and would require me to automate it myself, mencoder requires the input to also contain video, and abcde assumes the input is a CD. The ideal tool should be multi-threaded, and support inputing multiple files located in different directories simultaneously. CLI or GUI makes no matter. Does such a tool exist?

• Regular expression for Regular expressions?

  - by kavoir.com

  I have an app that enables the user to input a regular expression, my question is how to check against any input of regular expressions and make sure they are valid ones because if they are not there will be preg_match errors. I don't want to use the '@' before preg_match, so if there's a way to check the validity of the user input of regular expressions that'd be great. The regular expression system of PHP seems to be rather too complicated for me to come up with a regular expression for them. Any idea or any alternatives would be possible in achieving this?

• Working with expression AST:s

  - by Marcus

  Hi, Is there any best practice when working with AST:s? I have a parsed expression AST. ConstantExpression, BinaryExpression etc. I want to populate a GUI-dialog with information from the AST, and it's here where I get kinda confused because my code gets pretty messy. Example: expression = "Var1 > 10 AND Var2 < 20" I want to populate two textboxes with value 10 resp. 20 from the AST. What I'm doing now is a recursive method that checks for correct child expression-types (with .Net Is-operator) and acts accordingly and the code is really "smelly" :) Is there any design pattern, like Visitor or such, that makes this somewhat easier/more readable/maintainable ?

• How to simplify this Xpath expression ?

  - by Stephan

  Hi , I have the following XML code : <root> <a><l_desc/></a> <b><l_desc>foo</l_desc></b> <c><l_desc>bar</l_desc></c> </root> I want to match the l_desc nodes with a or b nodes as parent. For now, i use this xpath expression : //a/l_desc/.. | //b/l_desc/.. I would prefer writing something like this : //(a|b)/l_desc/.. Unfortunately, this expression is invalid. Do you have any idea for reducing the first expression ? Stéphan

• Grabbing values from Expression.Blend.SampleData

  - by Mitchell Skurnik

  I am trying to figure out how to grab a value from Expression.Blend.SampleData. If my id is equal to a drop down for example, I can grab it by doing this: ((Expression.Blend.SampleData.MyDatabase.something)(MyDropDown.SelectedItem)).description; I need some way to place my own value where (MyDropDown.SelectedItem) is. Visual studio wants me to convert it a "Expression.Blend.SampleData.MyDatabase.something" format. I have tried a few ways to do this but I have been unsuccessful. Any Ideas? EDIT I am starting to think there is no way in Silverlight to do this

• Reverse Expression.Like criterion

  - by Joel Potter

  How should I go about writing a backwards like statement using NHibernate criteria? WHERE 'somestring' LIKE [Property] + '%' Sub Question: Can you access the abstract root alias in a SQLCriterion expression? This is somewhat achievable using the SQLCriterion expression Expression.Sql("? like {alias}.[Property] + '.%'", value, NHibernateUtil.String); However, in the case of class inheritance, {alias} is replaced with the incorrect alias for the column. Example (these classes are stored in separate tables): public abstract class Parent { public virtual string Property { get; set; } } public class Child : Parent { } The above query executed with Child as the root type will replace {alias} with the alias to the Child table rather than the Parent table. This results in an invalid column exception. I need to execute a like statement as above where the property exists on the parent table rather than on the root type table.

• VB.NET logical expression evaluator

  - by Tim

  I need to test a logical expression held in a string to see if it evaluate to TRUE or FALSE.(the strig is built dynamically) For example the resulting string may contain "'dog'<'cat' OR (14 AND 4<6)". There are no variables in the string, it will logically evaluate. It will only contain simple operators = < < = <= and AND , OR and Open and Close Brackets, string constants and numbers. (converted to correct syntax && || etc.) I currently acheive this by creating a jscipt function and compiling it into a .dll. I then reference the .dll in my VB.NET project. class ExpressionEvaluator { function Evaluate(Expression : String) { return eval(Expression); } } Is there a simpler method using built in .NET functions or Lamdba expressions.

  - by bn

  This Regular expression if for MySQL query: I want to exclude this row because it has 'something' in side the bracket "bla bla bla bla bla bla (bla bla bla something)" However I want to include this row, because it does not have 'something' inside the bracket "bla bla bla (bla bla bla)" I tried this query but it didnt work.

• difference between Casini [IIS express] and VS Development server or Expression web

  - by anirudha

  MVC3 project can be run within Expression web and Visual studio as opened like a website not a project. they work same even if you open blogengine.net project in VS they take a time when you have more theme but expression web debug them in a second. well because theme design not matter for code. Expression web is a good because they save time for compile the code. even changes we make a little in design nothing in backend code.   i found a little difference between Casini and VS development server that if image putted in wrong way like <img src=”//img.png”/> instead of <img src=”/img.png”/> the error we make // instead of / that’s not worked in Expression web or Visual studio debugging but in Cassini it’s work fine.   Well i found that debug Blogengine.net in Expression web is a great thing because in VS they take a time like a minute to debug when you trying to debug first time. Expression Web save a time when we design themes within them and that’s much good option because web is also maked for design.   Well if you want to debug application faster then use casini but Expression web debugging is a good option when they take a long time to debug in Visual studio and EW debug them in a seconds.

• Excel Matching problem with logic expression

  - by abelenky

  I have a block of data that represents the steps in a process and the possible errors: ProcessStep Status FeesPaid OK FormRecvd OK RoleAssigned OK CheckedIn Not Checked In. ReadyToStart Not Ready for Start I want to find the first Status that is not "OK". I have attempted this: =Match("<>""OK""", StatusRange, 0) which is supposed to return the index of the first element in the range that is NOT-EQUAL (<) to "OK" But this doesn't work, instead returning #N/A. I expect it to return 4 (index #4, in a 1-based index, representing that CheckedIn is the first non-OK element) Any ideas how to do this?

• Convert Javascript Regular Expression to PHP (PCRE) Expression

  - by Matt

  Hi all, I am up to my neck in regular expressions, and I have this regular expression that works in javascript (and flash) that I just can't get working in PHP Here it is: var number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; var oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]' + '|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; var str = '(?:\"' + oneChar + '*\")'; var varName = '\\$(?:' + oneChar + '[^ ,]*)'; var func = '(?:{[ ]*' + oneChar + '[^ ]*)'; // Will match a value in a well-formed JSON file. // If the input is not well-formed, may match strangely, but not in an unsafe // way. // Since this only matches value tokens, it does not match whitespace, colons, // or commas. var jsonToken = new RegExp( '(?:false|true|null' +'|[\\}]' + '|' + varName + '|' + func + '|' + number + '|' + str + ')', 'g'); If you want it fully assembled here it is: /(?:false|true|null|[\}]|\$(?:(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ,]*)|(?:{[ ]*(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ]*)|(?:-?\b(?:0|[1-9][0-9]*)(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\b)|(?:"(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))*"))/g Interestingly enough, its very similar to JSON. I need this regular expression to work in PHP... Here's what I have in PHP: $number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; $oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; $string = '(?:\"'.$oneChar.'*\")'; $varName = '\\$(?:'.$oneChar.'[^ ,]*)'; $func = '(?:{[ ]*'.$oneChar.'[^ ]*)'; $jsonToken = '(?:false|true|null' .'|[\\}]' .'|'.$varName .'|'.$func .'|'.$number .'|'.$string .')'; echo $jsonToken; preg_match_all($jsonToken, $content, $out); return $out; Here's what happens if I try using preg_match_all(): Warning: preg_match_all() [function.preg-match-all]: Compilation failed: nothing to repeat at offset 0 in /Users/Matt/Sites/Templating/json/Jeeves.php on line 88 Any help would be much appreciated!

• Render Silverlight Animation to video file

  - by VOliveira

  Hi guys I need to be able to render a silverlight storyboard animation to video. The animated content itself could be simple UIElements, Images or even two or more videos playing at the same time. Several ideas came to mind like RenderTargetBitmap on a single frame basis, but: 1) I've never tested this against video embedded content 2) Don't know how to actually compose the video from the generated images. Expression Encoder was also on my mind, but I don't know if it's possible to integrate it in a Silverlight/XBAP app to fulfill what's expected from it. What's your opinion on this?

• d:DesignData issue, Visual Studio 2010 cant build after adding sample design data with Expression Bl

  - by Valko

  Hi, VS 2010 solution and Silverlight project builds fine, then: I open MyView.xaml view in Expression Blend 4 Add sample data from class (I use my class defined in the same project) after I add new sample design data with Expression blend 4, everything looks fine, you see the added sample data in the EB 4 fine, you also see the data in VS 2010 designer too. Close the EB 4, and next VS 2010 build is giving me this errors: Error 7 XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved. C:\Code\source\...myview.xaml and: Error 12 Object reference not set to an instance of an object. ... TestSampleData.xaml when I open the TestSampleData.xaml I see that namespace for my class used to define sample data is not recognized. However this namespace and the class itself exist in the same project! If I remove the design data from the MyView.xaml: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" it builds fine and the namespace in TestSampleData.xaml is recognized this time?? and then if add: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" I again see in the VS 2010 designer sample data, but the next build fails and again I see studio cant find the namespace in my TestSampleData.xaml containing sample data. That cycle is driving me crazy. Am I missing something here, is it not possible to have your class defining sample design data in the same project you have the MyView.xaml view?? cheers Valko

• Dynamic expression tree how to

  - by Savvas Sopiadis

  Hello everybody! Implemented a generic repository with several Methods. One of those is this: public IEnumerable<T> Find(Expression<Func<T, bool>> where) { return _objectSet.Where(where); } Given to be it is easy to call this like this: Expression<Func<Culture, bool>> whereClause = c => c.CultureId > 4 ; return cultureRepository.Find(whereClause).AsQueryable(); But now i see (realize) that this kind of quering is "limiting only to one criteria". What i would like to do is this: in the above example c is of type Culture. Culture has several properties like CultureId, Name, Displayname,... How would i express the following: CultureId 4 and Name.contains('de') and in another execution Name.contains('us') and Displayname.contains('ca') and .... Those queries should be created dynamically. I had a look in Expression trees (as i thought this to be a solution to my problem - btw i never used them before) but i cannot find anything which points to my requirement. How can this be costructed? Thanks in advance

• Matching math expression with regular expression?

  - by Ethan

  For example, these are valid math expressions: a * b + c -a * (b / 1.50) (apple + (-0.5)) * (boy - 1) And these are invalid math expressions: --a *+ b @ 1.5.0 // two consecutive signs, two consecutive operators, invalid operator, invalid number -a * b + 1) // unmatched parentheses a) * (b + c) / (d // unmatched parentheses I have no problem with matching float numbers, but have difficulty with parentheses matching. Any idea? If there is better solution than regular expression, I'll accept as well. But regex is preferred.

• Boolean Expression Evaluation in Java

  - by Trilok

  Hey everyone, Is there a relatively simpler (when compared with writing a parser) way to evaluate boolean expressions in Java? I do not want to use the JEP library. I have a String expression something like: (x 4 || x < 8 && p 6) [ I will replace the variables with values. Is there a way by which I can evaluate this expression? The problem is, this can be any level deep. So, writing a parser would be really complex. Thanks

• When are ASP.NET Expression Builders most useful?

  - by SkippyFire

  I saw an example of using Expression Builders, and creating your own Custom Expression Builder Classes here: http://aspnet.4guysfromrolla.com/articles/022509-1.aspx However, I fail to see the value in using this approach. It doesn't seem much easier than programmatically setting values in your code behind. As far as I can tell, the only thing you can do with them is set properties. Maybe they would be useful for setting defaults on certain controls? Can anyone shed light on where this ASP.NET feature becomes powerful?
