I’d highly suggest giving Code Complete 2 by Steve McConnell a read. His argument is that you should neither declare all of your variables in one line, nor should should declare them all at the top of a routine. So, don’t do this: function foo() { var a, b, c, d; /** * 20 lines … Read more
Use reflection: Method method = WhateverYourClassIs.class.getDeclaredMethod(“Method” + MyVar); method.invoke();
Try this instead, remove the SelectCommand property and SelectParameters: <asp:SqlDataSource ID=”SqlDataSource1″ runat=”server” ConnectionString=”<%$ ConnectionStrings:itematConnectionString %>”> Then in the code behind do this: SqlDataSource1.SelectParameters.Add(“userId”, userId.ToString()); SqlDataSource1.SelectCommand = “SELECT items.name, items.id FROM items INNER JOIN users_items ON items.id = users_items.id WHERE (users_items.user_id = @userId) ORDER BY users_items.date DESC” While this worked for me, the following code also … Read more
if echo “$long_str” | grep -q “$shrt_str”;then echo “found” fi or echo “$long_str” | grep -q “$shrt_str” && echo “found” || echo “not found” But since you are using bash shell, then use shell internals. No need to call external commands shrt_str=”guide” case “$long_str” in *”$shrt_str”* ) echo “Found”;; * ) echo “Not found”;; esac
Your problem stems from a misunderstanding of the or operator that is common to people learning programming languages like this. Yes, your immediate problem can be solved by writing x ~= 0 and x ~= 1, but I’ll go into a little more detail about why your attempted solution doesn’t work. When you read x … Read more
From Wikipedia The stdlib.h and stddef.h header files define a datatype called size_t1 which is used to represent the size of an object. Library functions that take sizes expect them to be of type size_t, and the sizeof operator evaluates to size_t. The actual type of size_t is platform-dependent; a common mistake is to assume … Read more
The SVG Parameter Variables Specification would do what you want but it’s unlikely ever to be completed, let alone implemented by UAs. Instead SVG looks like it will move towards attributes being CSS parameters at which point you could use CSS Calc. There is a light at the end of the tunnel for you though … Read more
The two different approaches have names: Lisp-1 and Lisp-2. A Lisp-1 has a single namespace for both variables and functions (as in Scheme) while a Lisp-2 has separate namespaces for variables and functions (as in Common Lisp). I mention this because you may not be aware of the terminology since you didn’t refer to it … Read more
You can declare a session variable in this way : SET @myvarname := ‘value’; or a local variable in this way : DECLARE my_variable varchar(30) also: DECLARE my_variable varchar(30) DEFAULT ‘value’
