  - by abatishchev

  I have my own type: CREATE TYPE MyType AS TABLE ( foo INT ) and a function receiving it as a parameter: CREATE FUNCTION Test ( @in MyType READONLY ) RETURNS @return MyType AS ... can it return MyType or only TABLE repeating MyType's structure: CREATE FUNCTION Test ( @in MyType READONLY ) RETURNS @return TABLE (foo INT) AS ... ?

• Are SharePoint site templates really less performant than site definitions?

  - by Jim

  So, it seems in the SharePoint blogosphere that everybody just copies and pastes the same bullet points from other blogs. One bullet point I've seen is that SharePoint site templates are less performant than site definitions because site definitions are stored on the file system. Is that true? It seems odd that site templates would be less performant. It's my understanding that all site content lives in a database, whether you use a site template or a site definition. A site template is applied once to the database, and from then on the site should not care if the content was created using a site template or not. So, does anybody have an architectural reason why a site template would be less performant than a site definition? Edit: Links to the blogs that say there is a performance difference: From MSDN: Because it is slow to store templates in and retrieve them from the database, site templates can result in slower performance. From DevX: However, user templates in SharePoint can lead to performance problems and may not be the best approach if you're trying to create a set of reusable templates for an entire organization. From IT Footprint: Because it is slow to store templates in and retrieve them from the database, site templates can result in slower performance. Templates in the database are compiled and executed every time a page is rendered. From Branding SharePoint:Custom site definitions hold the following advantages over custom templates: Data is stored directly on the Web servers, so performance is typically better. At a minimum, I think the above articles are incomplete, and I think several are misleading based on what I know of SharePoints architecture. I read another blog post that argued against the performance differences, but I can't find the link.

• Smarty debug mode not displaying included templates.

  - by Kyle Sevenoaks

  On www.euroworker.no/order I have set Smarty's debug mode on with {debug output=html} in the header, so it will debug every page. But it says: Smarty Debug Console included templates & config files (load time in seconds): no templates included And after a list of template variables, {$cart} Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 561962 bytes) in /home/euroworkerno/www/library/smarty/libs/plugins/modifier.debug_print_var.php on line 30 It also doesn't display a list of templates for any url.. This is strange, can anyone point me to why it won't display the lit of .tpls? I need to find some HTML comments that someone has left in to rid IE of a display bug. Thanks.

• Compatibility issues with <a> and calling a function(); across different web browsers

  - by Matthew

  Hi, I am new to javascript. I wrote the following function rollDice() to produce 5 random numbers and display them. I use an anchor with click event to call the function. Problem is, in Chrome it won't display, works fine in IE, in firefox the 5 values display and then the original page w/anchor appears! I am suspicious that my script tag is too general but I am really lost. Also if there is a display function that doesn't clear the screen first that would be great. diceArray = new Array(5) function rollDice() { var i; for(i=0; i<5; i++) { diceArray[i]=Math.round(Math.random() * 6) % 6 + 1; document.write(diceArray[i]); } } when I click should display 5 rand variables

• Merging two templates in iText

  - by Shaggy Frog

  Let's say I have two PDF templates created with Adobe Acrobat, which are both single-page, 8.5x11 documents. The first template (A.pdf) has content for the top half of the page. The second template (B.pdf) has content for the bottom half of the page. (It just so happens the content in both templates does not "overlap" each other.) I would like to use iText to take these two templates and create a single, "merged" template from it (C.pdf) that is only a single page (with A.pdf's content on the top half and B.pdf's content on the bottom half). (I do not want to "merge" these two files into a 2-page document. I need the final product to be a single page.) I will be running iText in a servlet environment (Tomcat 6) but I don't think that makes a difference to the answer. Is this possible?

• Whats the scope of a c function defined within objective-c class?

  - by roja

  I was reading up about bypassing objective-c's messaging to gain performance (irrelevant to this specific question) when i found an interesting bit of code: #import <Cocoa/Cocoa.h> @interface Fib : NSObject { } - (long long) cFib: (NSUInteger) number; @end @implementation Fib // c implementation of fib long long cFibIMP(NSUInteger number) { return (number < 3) ? 1 : cFib(number - 1) + cFib(number - 2); } // method wrapper for c implementation of fib - (long long) cFib: (NSUInteger) number { return cFibIMP(number); } @end My question is; when using c function, within an objective-c object, what scope is the c function (cFibIMP in this particular case) placed in? Does the objective-c class encapsulate the c function removing change of name-clash or is the c function simply dumped into the global scope of the whole objective-c program?

• Get a list/tuple/dict of the arguments passed to a function?

  - by digitala

  Given the following function: def foo(a, b, c): pass How would one obtain a list/tuple/dict/etc of the arguments passed in, without having to build the structure myself? Specifically, I'm looking for Python's version of JavaScript's arguments keyword or PHP's func_get_args() method. What I'm not looking for is a solution using *args or **kwargs; I need to specify the argument names in the function definition (to ensure they're being passed in) but within the function I want to work with them in a list- or dict-style structure.

  - by Ronnie Chester Lynwood

  Hello! I've got an ASP document that 5 years old. Actually I'm working with PHP but I must use ASP for a Windows Application. So I need someone to explain this function to me. Thanks anyway. //DNS SETTINGS ARE INCLUDED ALREADY. function Check_Is_Web_Locked() dim cmdDB , Ret OpenDatabase Set cmdDB = Server.CreateObject("ADODB.Command") With cmdDB .ActiveConnection = DBCon .CommandText = "TICT_CHECK_WEB_STATUS" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("RETURN_VALUE", adInteger, adParamReturnValue, 0) .Execute,,adExecuteNoRecords Ret = Trim(.Parameters("RETURN_VALUE")) End With Set cmdDB = Nothing CloseDatabase Check_Is_Web_Locked = Ret end function What does this functions do? Is "TICT_CHECK_WEB_STATUS" a StoredProcedure? If it's what are the coulumns that function looking for?

• PHP static function self:: in joomla JFactory class explanation?

  - by Carbon6

  Hi I'm looking at the code of Joomla and trying to figure out what exactly happends in this function. index.php makes a call to function $app = JFactory::getApplication('site'); jfactory.php code public static function getApplication($id = null, $config = array(), $prefix='J') { if (!self::$application) { jimport('joomla.application.application'); self::$application = JApplication::getInstance($id, $config, $prefix); } return self::$application; } application.php code.. public static function getInstance($client, $config = array(), $prefix = 'J') { static $instances; if (!isset($instances)) { $instances = array(); } ....... more code ........ return $instances[$client]; } Now I cannot figure out in function getApplication why is self:$application used. self::$application = JApplication::getInstance($id, $config, $prefix); $application is always null, what is the purpose of using this approach. I tryied modifying it to $var = JApplication::getInstance($id, $config, $prefix); and returnig it but it doesn't work. I would be very glad if someone with more knowledge could explain what is happening here detailed as possible. Many thanks.

• How to inline a function for only release build.

  - by Benjamin

  // common.h // This is foo funtion. It has a body. __inline void foo() { /* something */ } // a.cpp #include "common.h" // for foo function // Call foo // b.cpp #include "common.h" // for foo function // Call foo I would like to inline the foo function only when I build for release. -I dont want to inline functions for Debug build. I tried it but linker errors annoyed me. In this case, foo function's body is defined in common.h header file. so if I just do //common.h #if !defined(_DEBUG) __inline #endif void foo() { /* something */ } I will be met a link error in DEBUG build. Because two modules try to include common.h. I have no idea to solve it. Is it possible?

• Assign C++ instance method to a global-function-pointer ?

  - by umanga

  Greetings, My project structure is as follows: \- base (C static library) callbacks.h callbacks.c paint_node.c . . * libBase.a \-app (C++ application) main.cpp In C library 'base' , I have declared global-function-pointer as: in singleheader file callbacks.h #ifndef CALLBACKS_H_ #define CALLBACKS_H_ extern void (*putPixelCallBack)(); extern void (*putImageCallBack)(); #endif /* CALLBACKS_H_ */ in single C file they are initialized as callbacks.c #include "callbacks.h" void (*putPixelCallBack)(); void (*putImageCallBack)(); Other C files access this callback-functions as: paint_node.c #include "callbacks.h" void paint_node(node *node,int index){ //Call callbackfunction . . putPixelCallBack(node->x,node->y,index); } I compile these C files and generate a static library 'libBase.a' Then in C++ application, I want to assign C++ instance method to this global function-pointer: I did something like follows : in Sacm.cpp file #include "Sacm.h" extern void (*putPixelCallBack)(); extern void (*putImageCallBack)(); void Sacm::doDetection() { putPixelCallBack=(void(*)())&paintPixel; //call somefunctions in 'libBase' C library } void Sacm::paintPixel(int x,int y,int index) { qpainter.begin(this); qpainter.drawPoint(x,y); qpainter.end(); } But when compiling it gives the error: sacmtest.cpp: In member function ‘void Sacm::doDetection()’: sacmtest.cpp:113: error: ISO C++ forbids taking the address of an unqualified or parenthesized non-static member function to form a pointer to member function. Say ‘&Sacm::paintPixel’ sacmtest.cpp:113: error: converting from ‘void (Sacm::)(int, int, int)’ to ‘void ()()’ Any tips?

• How to use two parameters pointing to the same structure in one function ?

  - by ZaZu

  Hey guys, I have my code below that consits of a structure, a main, and a function. The function is supposed to display two parameters that have certain values, both of which point to the same structure. The problem I dont know how to add the SECOND parameter onto the following code : #include<stdio.h> #define first 500 #define sec 500 struct trial{ int f; int r; float what[first][sec]; }; int trialtest(trial *test); main(){ trial test; trialtest(&test); } int trialtest(trial *test){ int z,x,i; for(i=0;i<5;i++){ printf("%f,(*test).what[z][x]); } return 0; } I need to add a new parameter test_2 there (IN THE SAME FUNCTION) using this code : for(i=0;i<5;i++){ printf("%f,(*test_2).what[z][x]); How does int trialtest(trial *test) changes ? and how does it change in main ? I know that I should declare test_2 as well, like this : trial test,test_2; But what about passing the address in the function ? I do not need to edit it right ? trialtest(&test); --- This will remain the same ? So please, tell me how would I use test_2 as a parameter pointing to the same structure as test, both in the same function.. Thank you !! Please tell me if you need more clarification

• Reporting. MS Word templates population required

  - by Andrew Florko

  Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

• Any way in C++ to forward declare a function prototype?

  - by jsyjr

  I make regular use of forward class declarations and pointers to such classes. I now have a need to pass a function pointer through a number of layers. I would prefer to include the header that declares my function pointer's prototype only into the module that dereferences a function pointer rather than into each layer that simply passes along that pointer value. Is this possible?

• How to create a function and pass in variable length argument list?

  - by Jian Lin

  We can create a function p in the following code: var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = function() { console.log(arguments); }; } but the arguments are passed like an array to console.log, instead of passed one by one as in console.log(arguments[0], arguments[1], arguments[2], ... Is there a way to expand the arguments and pass to console.log like the way above? Note that if the original code were var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = console.log; } then it works well on Firefox and IE 8 but not on Chrome.

• C - What is the proper format to allow a function to show an error was encountered?

  - by BrainSteel

  I have a question about what a function should do if the arguments to said function don't line up quite right, through no fault of the function call. Since that sentence doesn't make much sense, I'll offer my current issue. To keep it simple, here is the most relevant and basic function I have. float getYValueAt(float x, PHYS_Line line, unsigned short* error) *error = 0; if(x < line.start.x || x > line.end.x){ *error = 1; return -1; } if(line.slope.value != 0){ //line's equation: y - line.start.y = line.slope.value(x - line.start.x) return line.slope.value * (x - line.start.x) + line.start.y; } else if(line.slope.denom == 0){ if(line.start.x == x) return line.start.y; else{ *error = 1; return -1; } } else if(line.slope.num == 0){ return line.start.y; } } The function attempts to find the point on a line, given a certain x value. However, under some circumstances, this may not be possible. For example, on the line x = 3, if 5 is passed as a value, we would have a problem. Another problem arises if the chosen x value is not within the interval the line is on. For this, I included the error pointer. Given this format, a function call could work as follows: void foo(PHYS_Line some_line){ unsigned short error = 0; float y = getYValueAt(5, some_line, &error); if(error) fooey(); else do_something_with_y(y); } My question pertains to the error. Note that the value returned is allowed to be negative. Returning -1 does not ensure that an error has occurred. I know that it is sometimes preferred to use the following method to track an error: float* getYValueAt(float x, PHYS_Line line); and then return NULL if an error occurs, but I believe this requires dynamic memory allocation, which seems even less sightly than the solution I was using. So, what is standard practice for an error occurring?

• how to .call() on the unnamed function in javascript?

  - by Anonymous

  Let's suppose I have button #click, And suppose I bind the on click event as follows: $('#click').click(function(){ alert('own you'+'whatever'+$(this).attr('href')); }); But I want this to refer to some other element, let's say #ahref. If it was a named function I would simply refer it by name: foo.call('#ahref'); How could I use .call() though, if the function is called inline and does not have a name?

• jquery - How to reference two div elements for a single function?

  I Have a function that references a specific input text box. I would like to extend the function to be used by two specific input text boxes. Rather than duplicate the code for the other text box, can anyone advise on how to reference the other? Here it uses #Tags, but if i wanted it to reference #Tags2 also, how could I do that? $(function () { $('#Tags').tagSuggest({ separator: ", ", tagContainer: 'div', tags: ["tag1","tag2"] }); });

  When I have some function of type like f :: (Ord a) => a -> a -> Bool f a b = a > b I should like make function which wrap this function with not. e.g. make function like this g :: (Ord a) => a -> a -> Bool g a b = not $ f a b I can make combinator like n f = (\a -> \b -> not $ f a b) But I don't know how. *Main> let n f = (\a -> \b -> not $ f a b) n :: (t -> t1 -> Bool) -> t -> t1 -> Bool Main> :t n f n f :: (Ord t) => t -> t -> Bool *Main> let g = n f g :: () -> () -> Bool What am I doing wrong? And bonus question how I can do this for function with more and lest parameters e.g. t -> Bool t -> t1 -> Bool t -> t1 -> t2 -> Bool t -> t1 -> t2 -> t3 -> Bool

• How to declare a pointer to a variable as a parameter of a function in C++?

  - by Keand64

  I have a function that takes a pointer to a D3DXVECTOR3, but I have no reason to declare this beforehand. The most logical solution to me was using new: Function( //other parameters, new D3DXVECTOR3(x, y, 0)); but I don't know how I would go about deleting it, beign intitialized in a function. My next thought was to use the & operator, like so: Function( //other parameters, &D3DVECTOR3(x, y, 0)); but I don't know if this is a valid way to go about doing this. (It doesn't get an error, but neither does int *x; x = 50;). So should I use new, &, or some other technique I'm overlooking?
