Visual Basic - How to use a variable from one function in another
As Plutonix stated, this is a scope issue. Move the declaration of your 'rateNbr' variable out to class level, and remove the local declarations inside your functions: Dim rateNbr As String ' <-- out at class level it will be accessible from both functions Public Function FuncRateCheckFile() ... ' REMOVE both the decalarations of "rateNbr" that are INSIDE your functions ... End F

Implementing MIPS instructions for an absolute value function
So, ieee754.Read about it.Think about it.Realize it's signed-magnitude. On MIPS, it so happens that the sign-bit is in the same position in the word as the most significant bit in an integer. load float as integer x AND x with 0x7fffffff store x as float

Delphi - OmniThreadLibrary Parallel.ForEach with Records
I had some confusion with the example - a queue wasn't necessary for this application. Appropriate example code would be: function GetMyRecordArray(n: Integer): myRecordArray; {Just a type of Array of myRecord} var a, b: Double; begin SetLength(RESULT, n) Parallel.ForEach(1, n).Execute( procedure (const value: integer) begin a := {SOME FUNCTION OF value}; b := {SOME FU

Why am I getting a "No matching subprogram was found." error?
The variable yazi_byte needs to be constrained explicitly, as the error message says. It looks like it has a range of eight bit, so: VARIABLE yazi_byte: std_logic_vector(7 downto 0); would work.

PLSQL using cursors or functions to query repeated data
Since you know that the query should always return exactly 1 row, a function returning a %ROWTYPE makes much more sense. That takes care of throwing an exception if 0 rows are returned or if more than 1 row is returned which sounds to be the correct behavior. That makes the calling code simpler as well since you're not dealing with iterating over a cursor.

Haskell syntax regarding pattern matching in functions
(x:xs) is not a tuple. The parentheses are just there to express precedence. x:xs is a pattern that matches the list constructor (which is the infix operator :, often pronounced 'cons') where the list head is bound to the variable x and the tail is bound to the variable xs. Because of Haskell's precedence rules, your third line without parentheses myLength x:xs = 1 + myLength xs would be parsed

Fortran Class (*) in Function Result
I am not sure that I recommend doing what I write below, preferring instead keeping to generics, but I will attempt to explain. The first thing to note is that, as the error message states, for a non-dummy argument polymorphic variable (such as c) that variable must have the pointer or allocatable attribute. Here, it makes sense for the function result to be allocatable. After adding the alloca

Pipelining get-content to own function
Instead of function try filter: filter Test-Pipeline { ... } This is basically a function with a processing block (which you need to process pipeline objects). Alternatively you can write a function with this block and optional begin and end blocks: function Test-Pipeline { begin { } process { ... } end { } } More info: http://technet.microsoft.com/en-us/ma

Upper case a full string without using .upper function? PYTHON
ord("A") --> 65 ord("B") --> 66 ... ord("a") --> 97 ord("b") --> 98 ... So whenever you want to change lowercase character to uppercase without using upper() function, you can just find the ASCII value of lowercase using ord() function, subtract 32 (which is the difference between uppercase and lowercase) and then use chr() func

Invalid Redeclaration of function in Swift
This actually looks like a bug in the documentation. In the section I originally linked to, Local and External Parameter Names for Methods the follow explanation is written. This default behavior effectively treats the method as if you had written a hash symbol (#) before the numberOfTimes parameter: func incrementBy(amount: Int, #numberOfTimes: Int) { count += amount * numberOfTimes }

Is it possible to use synchronous process in functions?
No, you can't have a clocked process inside a function. You can use a loop, though: if rising_edge(clk) then for i in 0 to x'length - 1 loop y(i) <= x(i); -- or whatever operation end loop; end if; You can wrap the for-loop portion only in a function if you really want: function f(x : std_logic_vector) return std_logic_vector is variable result : std_logic_vector(x'range); begin

Cscope output all parameters
I am not sure this is achievable. However, as a workaround you could use grep, which is more "flexible" and parse the output of: grep -Ri -A 2 "type func" . This would print the lines that contains "type func" and with -A 2 the 2 following lines. You can also use regex to get the output until the closing ) of function declaration.

Where, when and why use functions?
The practice we use at our company is to only use functions when a piece of code is reused, were the function is located depends on what is reusing the function. If it is only used, lets say within a class then we would keep the function within that scope. If is it reused by other classes then most likely we would add it to a utility class accessible by other classes unless it is directly associa

Function Ambiguation
A call such as split_to_str(a,b,c,d) where a,b,c,d are all strings can't be unequivocally identified with only one of your two functions. That's ambiguous.

From your recent trail of Qs and As you've already discussed this with others, I have nothing to add to what has gone before. I'm sur

concatenating functions in python?
You can't concatenate functions, no. You are using print, which writes directly to your terminal. You'd have to produce strings instead, which you can concatenate, then print separately: def lines(): return "| | |" def bottom_top(): return "+-----------+-----------+" def my_square(): print bottom_top() for i in range(4): print lines() print bottom_top

MIPS Programs with more than 4 arguments
There are multiple calling conventions, you should figure out which one you are supposed to follow. If you have no documentation, you could look at compiler-generated assembly code, or use a debugger. That said, judging from the fact that only 4 arguments are passed on the stack, you seem to be using the O32 calling convention. This means, the stack upon entry to your function contains 4 argument

Can you explain "this" in javascript?
probably asked many many times but: The 'this' in this.firstName is the object which you're currently 'working on', since the funcion will be called from some object, you can use a generic 'this' to refer to whichever object is calling it. If it sounds too technical use this as an example: You're creating an object called var, which has several attributes (firstName, lastName) and an annonymous

You have too many parens!
