Was going to call this "Eval won't give me the Time of Day," but thought that too cute. I'm kind of having the opposite problem from the suggested questions I see for my title, so here goes: Visual Studio 2008 Pro, SQL Express 2008, Vista. Web Project, where I'm opening records from an Event Table with JOINed info from a Facilities tab...
I'd like to get value of variable named $(MYVAR)_SOME_SUFFIX in the b.mak makefile.

Lets say I have an array which has n dimensions. Now in order to access a slot you typically use: array [1][0] What if the number of dimensions are not known at compile-time, is there an easy access like: slot = "1,0" array [slot] // accessing 1,0 Which means I can also easily navigate back and forth slot += ",2" array [slo...
These weekend I've been tearing down to pieces Michele Simionato's decorator module, that builds signature-preserving decorators. At the heart of it all there is a dynamically generated function, which works something similar to this... src = """def function(a,b,c) :\n return _caller_(a,b,c)\n""" evaldict = {'_caller_' : _caller_} co...
I'm trying to improve the speed of our server but I would like to have your view of that before modifying everything. I have a high read rate on my file system. Right now we are using regular PHP file. I wonder if I can cache these file in Memcache and later do an eval on the code if it will be faster than letting these file get interpr...
Quick Question. Eval in JavaScript is unsafe is it not? I have a JSON object as a string and I need to turn it into an actual object so I can obtain the data: function PopulateSeriesFields(result) { data = eval('(' + result + ')'); var myFakeExample = data.exampleType } If it helps I am using the $.ajax method from jQuery.

hi all, i all the years i have been developing in php, i've always heard that using eval() is evil. considering the following code, wouldn't it make sense, to use the second (and elegant) option? if no, why? // $type is the result of an SQL statement // e.g. SHOW COLUMNS FROM a_table LIKE 'a_column'; // hence you can be pretty sure ab...
I have a piece of Perl code somewhat like the following (strongly simplified): There are some levels of nested subroutine calls (actually, methods), and some of the inner ones do their own exception handling: sub outer { middle() } sub middle { eval { inner() }; if ( my $x = $@ ) { # caught exception if (ref $x eq 'ARRA...
I have to convert an MSSQL stored proc that passes a varchar that is a query. The proc has the following command: INSERT INTO Results EXEC (@Expresion); This isn't working. I'm pretty sure that EXEC and EXECUTE arent MySQL commands but CALL doesn't work either. Does anyone know if its even possible to have something like JavaScript'...
Hi, I am trying very hard to pass three parameters to a javascript function from within a itemtemplate of a gridview: For one parameter, it works fine: <asp:HyperLink ID="hypComment" runat="server" Font-Bold="True" NavigateUrl='<%# Eval("CCN", "javascript:ShowCommentPopUp({0});") %>'>Add </asp:HyperLink> where CCN is my column in gr...

Hi Guys, we need to evaluate a value in an object in run time while we have a textual statement of the exact member path for example: myobject.firstMember.secondMember[3].text we thought of parsing this textual statement using regex and then evaluate the text value by using reflection but before we do that i wonder if C# support some kin...

Given that EVAL is Evil how do I create an Array name dynamically: I have a bunch of Arrays and I need to reference different ones depending on what the user clicks. This bit of code gives me the array object: (eval(calendarObject.id + '7')) But eval is bad, so how to do I construct an Array name and then reference it? Here's a bi...
