• Validation Rules in Webtesting using VS2010

  - by Lexipain

  I'm creating a simple webtest (Recorded Web performance test) that makes sure that a correct error message is displayed if i try to login with a username that does not exist. However, there are two types of error messages that handle incorrect login info. One is for all the usernames that do not exist and therefore are not allowed, and the other is for usernames that start with the letter 'Q' (which is not allowed for a few reasons). Now what i want to do is use the 'Find Text' validation rule and the test should pass if ONE of the 'Find Text' parameters is found, and in that case i want the second 'Find Text' rule to be ignored so it doesn't fail the test. In other words the test should always pass if one of the 'Find Test' rules is found. How can i achieve that? Is there some if,else statement that i can use for this?

• Symfony Rewrite rules on Zeus webserver

  - by Ben

  I would like to run a symfony project on a zeus webserver, however i cannot get the rewrite rules to work. Has anyone done this successfully The symfony .htaccess is as follows: Options +FollowSymLinks +ExecCGI <IfModule mod_rewrite.c> RewriteEngine On # uncomment the following line, if you are having trouble # getting no_script_name to work #RewriteBase / # we skip all files with .something #RewriteCond %{REQUEST_URI} \..+$ #RewriteCond %{REQUEST_URI} !\.html$ #RewriteRule .* - [L] # we check if the .html version is here (caching) RewriteRule ^$ index.html [QSA] RewriteRule ^([^.]+)$ $1.html [QSA] RewriteCond %{REQUEST_FILENAME} !-f # no, so we redirect to our front web controller RewriteRule ^(.*)$ index.php [QSA,L] </IfModule> From what I can tell the following should work on zeus: match URL into $ with (^(.*)$) if matched then set URL = index.php But it doesn't... I can only load the home page from / all other pages just 404. Thanks..

• mod_rewrite different rules for different pages

  - by Sophia Gavish

  Hi, I'm trying to understand how mod_rewrite works. I've been using it before but this week I tried to write rules to a new website and it doesn't works. I want to make a rule to make : www.example.com/media/?gallery=galleryname&album=albumname&pid=pictureid looks like: www.example.com/media/galleryname/albumname/pictureid The rule is: RewriteRule ^([^/])/([^/])/([^/]*)$ /media/?gallery=$1&album=$2&pid=$3 [L] and here is the code below: Options -Indexes Options +FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{REQUEST_METHOD} !^(TRACE|TRACK|GET|POST|HEAD)$ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^([^/])/([^/])/([^/]*)$ /media/?gallery=$1&album=$2&pid=$3 [L] I really want to know what I'm missing, because I tried some examples and it looks fine to me. maybe because /media/ is an actual folder the rule is wrong? Thanks.

• More HtAccess Rewrite Rules

  - by pws5068

  Greetings all, I need help combining some htaccess rewrites, these crazy regular expressions screw with my head. So I have a folder structure something like this: /www/mysite.com/page/member/friends.php /www/mysite.com/page/video/videos.php /www/mysite.com/page/messages/inbox.php The URLs get rewritten to this: mysite.com/member/friends.php mysite.com/video/videos.php mysite.com/messages/inbox.php (Notice the /page/ folder is hidden in the url, but I keep it on the server for better file organization) The rewrite rules look something like this: (I'm new so correct me if they are flawed) RewriteRule ^video/(.*)$ /page/video/$1 [NC] RewriteRule ^member/(.*)$ /page/member/$1 [NC] RewriteRule ^messages/(.*)$ /page/messages/$1 [NC] Now, I also need to do a completely different rewrite to a file called lobby.php inside of the member folder: After the original rewrites, a sample url looks like: mysite.com/member/lobby.php?member=pws5068 I need a new rewrite to make it look like this: mysite.com/pws5068 Thank you for bearing with my super-long question here. How can I make this happen?

• C99 strict aliasing rules in C++ (GCC)

  - by Checkers

  As far as I understand, GCC supports all of its C99 features in C++. But how is C99 strict aliasing handled in C++ code? I know that casting with C casts between unrelated types is not strict-aliasing-safe and may generate incorrect code, but what about C++? Since strict aliasing is not part of C++ standard (is that correct?), GCC must be specifying the semantics itself. I figure const_cast and static_cast cast between related types, hence they are safe, while reinterpret_cast can break strict aliasing rules. Is this a correct understanding?

• CALayer not obeying object ownership rules?

  - by eaigner

  I have a custom CALayer - UIProgressLayer - for simulating a progress bar. There is a dispatched GC timer involved to animate its intermediate state. So thats the layer I'm talking about here, although i don't think the problem is restricted to this particular subclass because a CALayer with only the -release and -dealloc overridden produces the same outcome. The problem is when i send this layer, for instance, a theLayer.opacity = 0.5f a -release message is sent to the layer, thus deallocating my layer. Why is this happening? Has it something to do with how the whole CA system works? But it still has to obey the object ownership rules right? I was thinking maybe it creates a copy of that layer for the fading, but that's not the case.

• Common optimization rules

  - by mafutrct

  This is a dangerous question, so let me try to phrase it correctly. Premature optimization is the root of all evil, but if you know you need it, there is a basic set of rules that should be considered. This set is what I'm wondering about. For instance, imagine you got a list of a few thousand items. How do you look up an item with a specific, unique ID? Of course, you simply use a Dictionary to map the ID to the item. And if you know that there is a setting stored in a database that is required all the time, you simply cache it instead of issuing a database request hundred times a second. I guess there are a few even more basic ideas. I am specifically not looking for "don't do it, for experts: don't do it yet" or "use a profiler" answers, but for really simple, general hints. If you feel this is an argumentative question, you probably misunderstood my intention.

• Using ANTLR with Left-Recursive Rules

  - by CNevin561

  Basically Ive written a Parse for a language with just basic arithmetic operators ( +, -, * / ) etc, but for the minus and plus cases, the Abstract Syntax Tree which is generated has parsed them as right associative when they need to be left associative. Having a googled for a solution, i found a tutorial that suggests rewriting the rule from: Expression ::= Expression <operator> Term | Term as Expression ::= Term <operator> Expression*. However in my head this seems to generate the tree the wrong way round. Any pointers on a way to resolve this issue?

• Using different validation rules based on user input.

  - by chiefanov

  I have a simple form: a combobox and a textbox. My combobox has 2 values: A and B. When value A is selected I want textbox to use a validation rule. When value B is selected there should be no validation rules applied to the textbox. I've read an article that has a solution and I'm trying to use it, but had no luck so far, and I think there might be a more elegant solution. Has anyone done anything like this before? Any ideas are highly appreciated.

• Ruby syntax checking in vim

  - by roybotnik

  Hi everyone, I use vim with various plugins for editing ruby code. I have proper syntax highlighting set up but I was wondering if anyone knew of a way to get ruby syntax checking, similar to what you might see in an IDE such as visual studio, radrails, etc? Something that would simply turn stuff red or break highlighting when I'm missing an 'end' or have an improperly constructed line of code would be sweet. I googled and came across this plugin, http://github.com/scrooloose/syntastic/tree/master but I was wondering if anyone had any better suggestions.

• Scintilla custom syntax highlighting not working

  - by Nilbert

  I have a Scintilla control that I create in C#, and the syntax highlighting doesn't work. It sets the font correctly which tells me that the file is being loaded, but the syntax highlighting doesn't work at all: Scintilla r = new Scintilla(); r.Dock = DockStyle.Fill; r.ConfigurationManager.IsUserEnabled = true; r.ConfigurationManager.CustomLocation = "langs.xml"; r.ConfigurationManager.Language = "rb"; r.Margins[0].Width = 40; r.Indentation.UseTabs = true; r.Indentation.IndentWidth = 4; r.Indentation.ShowGuides = true; r.Indentation.TabIndents = true; r.Indentation.TabWidth = 4; r.Indentation.SmartIndentType = SmartIndent.Simple; and the configuration file is this: http://codepad.org/DAjCrlPT in langs.xml. (The code won't fit here.) Can someone tell me why this is not working?

• Is there a calculator with LaTeX-syntax?

  - by Jørgen Fogh

  When I write math in LaTeX I often need to perform simple arithmetic on numbers in my LaTeX source, like 515.1544 + 454 = ???. I usually copy-paste the LaTeX code into Google to get the result, but I still have to manually change the syntax, e.g. \frac{154,7}{25} - (289 - \frac{1337}{42}) must be changed to 154,7/25 - (289 - 1337/42) It seems trivial to write a program to do this for the most commonly used operations. Is there a calculator which understand this syntax? EDIT: I know that doing this perfectly is impossible (because of the halting problem). Doing it for the simple cases I need is trivial. \frac, \cdot, \sqrt and a few other tags would do the trick. The program could just return an error for cases it does not understand.

• syntax in sqldatasource selectcommand

  - by netNewbi3

  Hi, My SqlDataSource selectcommand is dynamically changed by the String.Format functionality of the Eval one-way databinding syntax. It works ok. However I need to put together two columns values with a space in the middle (ItemType + '" "' + ItemDescription As ItemInfo) but I can't get the syntax correct as I get the message: "The server tag is not well formed" Can you help? Many thanks <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:conn %>" SelectCommand='<%# Eval("TypeID", "SELECT ItemID, ItemType, ItemType + '" "' + ItemDescription As ItemInfo WHERE ItemType = {0}")%>'> </asp:SqlDataSource>

• How to write a linter?

  - by jbdavid

  In my day job I, and others on my team write a lot of hardware models in Verilog-AMS, a language supported primarily by commercial vendors and a few opensource simulator projects. One thing that would make supporting each others code more helpful would be a LINTER that would check our code for common problems and assist with enforcing a shared code formatting style. I of course want to be able to add my own rules and, after I prove their utility to myself, promote them to the rest of the team.. I don't mind doing the work that has to be done, but of course also want to leverage the work of other existing projects. Does having the allowed language syntax in a yacc or bison format give me a leg up? or should I just suck each language statement into a perl string, and use pattern matching to find the things I don't like? (most syntax and compilation errors are easily caught by the commercial tools.. but we have some of our own extentions.)

• Avoiding Mixup of Language Details

  - by DarenW

  Today someone asked me what was wrong with their source code. It was obvious. "Use double equals in place of that single equal in that if statement. Um, i think..." As i remember some languages actually take a single equals for comparison. Since i sometimes forget or mix up the syntax details among the several languages i use, i stepped over to my laptop to try a quickie experiment... It costs a bit of time and is a break in the flow to try "quick" experiments (though maybe the practice is good for memory.) What tips do you have for keeping straight in your mind the syntax (and other) details of multiple languages? (And nowadays, this applies just as well to the many wiki-like markups!)
