  • CSS3 - Validator - RGBA wrong?

    - by poru
    I'm using the W3C CSS Validator with the Profile CSS3 but the validator says that my CSS rgba()'s are wrong. I looked up the Color Module Level 3, and the syntax is the same as mine. I also tried the Dev-Validator, same result. Example input: div.class { border: 1px solid rgba(0, 0, 0, 0.5); } Am I wrong or why does the validator say that I have that many mistakes with rgba?

  • Python 3.1, trying to unescape html/unicode/xml characters

    - by Sho Minamimoto
    I found my problem here, but there is only an answer for Python 2.6. Basically, I need to unescape strings such as this: 'a altieri_joão' to show the proper characters. http://stackoverflow.com/questions/990169/how-do-convert-unicode-escape-sequences-to-unicode-characters-in-a-python-string I need to do this in 3.1, but when I try print (u'a altieri_jo&#xe3;o') if gives me invalid syntax. And when I try name.decode('latin-1') it says 'str' has no method 'decode'.

  • Objective-C Xcode: Prefix.pch question?

    - by Johannes Jensen
    I have two files independant on each other. Let's just call it Class1 and Class2. In Class1, I need Class2, and in Class2 I need Class1. I have a prefix file where I include all my files, and I get some syntax errors because I do #import "Class1.h" #import "Class2.h" How would I define both of them so they can use each other? What am I doing wrong?

  • Using an HTML Textbox in place of an ASP.NET TextBox

    - by Velika
    If I add this to the ASPX page: <input id="Text1" type="text" value="Text1Value" /> I would expect to see "Text1" in the list of Request Form keys even WITHOUT setting the runat=Server property. ? request.Form.AllKeys I realize that if I do set that propery, then I will have a server-sided HTML control that I can reference using the name "Text1," but shouldn't I be able to access the text in the text box using the following VB.NET syntax? request.Form("Text1")

  • How do I use sqlite3 PRAGMA user_version in Objective-c?

    - by mobibob
    I am trying to check the user_version of the sqlite DB. I have an admin tool to bump the version, but I don't understand the syntax of the pragma statement. I am expecting to test the value in an if-statement. Can someone provide a code sample? When I embed the pragma statement in my objective-c code, the compiler throws an error.

  • Configuration problems with django and mod_wsgi

    - by Jimbo
    Hi, I've got problems on getting django to work on apache 2.2 with mod_wsgi. Django is installed and mod_wsgi too.

  • Ndepend CQL to query types out of assembly wildcard

    - by icelava
    In order to determine what low-level framework types a web application is directly using, one has to define each and every assembly involved. SELECT TYPES FROM ASSEMBLIES "Company.System.Framework", "Company.System.Framework.ReferenceLookup", "Company.System.Framework.Web", "Company.System.Framework.Security", "Company.System.Framework.Logging", "Company.System.Framework.DMS" WHERE IsDirectlyUsedBy "WebAssembly" I cannot find any syntax to wildcard the list of assemblies. Is there no way to shortcut this? We have a lot of framework level assemblies. i.e. Company.System.Framework.*

  • asp.net xml editor control

    - by Peter Goras
    All, I am looking for an asp.net xml editor control. Not a WYSIWYG editor like freetextbox or a javascript syntax highlighter but something that would make editing xml in the browser a bit easier than just as text in a textarea. maybe some non-editable areas, collapsable nodes, xsd validation etc. any ideas?

  • How does mysql define DISTINCT() in reference documentation

    - by goran
    EDIT: This question is about finding definitive reference to MySQL syntax on SELECT modifying keywords and functions. /EDIT AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax, but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best EDIT After asking the same question on mysql forums I learned that while parsing the SQL mysql does not care about whitespace between functions and column names (but I am still missing a reference). As it seems you can have whitespace between functions and the parenthesis SELECT LEFT (field1,1), field2... and get mysql to understand it as SELECT LEFT(field,1) Similarly SELECT DISTINCT(field1), field2... seems to get decomposed to SELECT DISTINCT (field1), field2... and then DISTINCT is taken not as some undefined (or undocumented) function, but as SELECT modifying keyword and the parenthesis around field1 are evaluated as if they were part of field expression. It would be great if someone would have a pointer to documentation where it is stated that the whitespace between functions and parenthesis is not significant or to provide links to apropriate MySQL forums, mailing lists where I could raise a question to put this into reference. EDIT I have found a reference to server option IGNORE SPACE. It states that "The IGNORE SPACE SQL mode can be used to modify how the parser treats function names that are whitespace-sensitive", later on it states that recent versions of mysql have reduced this number from 200 to 30. One of the remaining 30 is COUNT for example. With IGNORE SPACE enabled both SELECT COUNT(*) FROM mytable; SELECT COUNT (*) FROM mytable; are legal. So if this is an exception, I am left to conclude that normally functions ignore space by default. If functions ignore space by default then if the context is ambiguous, such as for the first function on a first item of the select expression, then they are not distinguishable from keywords and the error can not be thrown and MySQL must accept them as keywords. Still, my conclusions feel like they have lot of assumptions, I would still be grateful and accept any pointers to see where to follow up on this.

  • How to use Python list comprehension (or such) for retrieving rows when using MySQLdb?

    - by Erik Nygren
    Hey all, I use MySQLdb a lot when dealing with my webserver. I often find myself repeating the lines: row = cursor.fetchone() while row: do_processing(row) row = cursor.fetchone() Somehow this strikes me as somewhat un-pythonic. Is there a better, one-line way to accomplish the same thing, along the lines of inline assignment in C: while (row = do_fetch()) { do_processing(row); } I've tried figuring out the syntax using list comprehensions, but I can't seem to figure it out. Any recommendations? Thanks, Erik

  • Are there any reserved words in SQLite?

    - by DanM
    Three questions about reserved words: Are there any reserved words in SQLite? If so, what are they? If there are reserved words, is the correct syntax for using one of them as a column or table name still to surround it with brackets? E.g., [User] or [Name]? Are there any implications with using words that are reserved in other flavors of SQL (e.g., SQLServer) but not reserved in SQLite when using ADO.NET to query a SQLite database?
