  • how/resources to compile a procedural language into [sql]

    - by Philip
    I am looking into the possibility/feasibility/resources for building a cross compiler which takes a procedural or Object Oriented language like C, or Java and compiling it into SQL. I understand that the advantage of SQL code is performing set operations which is fundamentally different from procedural languages which generally process 1 at a time. If anyone has done this before, or if it is thought of as too complicated to do or any other ideas/concerns/suggestions would be greatly appreciated. Thanks in advance Philip

  • Why does Visual Studio sometimes add a number when creating page events in codebehinds?

    - by Kevin Pang
    When writing up a codebehind in Visual Studio for ASP.NET web forms applications, I often use the dropdowns at the top of the window to autogenerate page event handlers (e.g. Page_Load, Page_PreRender). I've noticed that sometimes Visual Studio likes to add numbers to these function names like "Page_Load1" or "Page_PreRender2". Programatically speaking, this has no effect on the code. But stylistically, I find it a bit ugly. Is there any way to get rid of this behavior?

  • Testing a Generic Class

    - by Jonas Gorauskas
    More than a question, per se, this is an attempt to compare notes with other people. I wrote a generic History class that emulates the functionality of a browser's history. I am trying to wrap my head around how far to go when writing unit tests for it. I am using NUnit. Please share your testing approaches below. The full code for the History class is here (http://pastebin.com/ZGKK2V84).

  • Mindblowing jQuery Weirdness

    - by Jason
    ...at least to me. This code used to work fine. I'm pretty sure nothing has changed, but now all of the sudden it behaves oddly. Basically I'm trying to create inline editing functionality. When the user clicks on the link, it dynamically generates a textbox and a confirm and cancel link. I'm having problems with the cancel link not removing everything in the cell. HTML: ... <td class="bid"> <a href="javascript:" class="102093" title="Click to modify bid">$0.45</a> </td> ... Binding jQuery (in $(function())): $('.bid a').live('click', renderBidChange); .... $('.report_table .cancel').live('click', cancelUpdate); renderBidChange (this function creates the dynamic elements): function renderBidChange(){ var cpc = $(this); var value = cpc.text().replace('$', ''); var cell = cpc.parent('.bid'); cpc.hide(); var input = document.createElement('input'); $(input).attr({type:'text',class:'dynamic cpc-input'}).val(value); cell.append(input); var accept = document.createElement('a'); $(accept).addClass('accept').attr({'href':'javascript:', 'title':'Accept Changes'}).text('Accept Changes'); cell.append(accept); var cancel = document.createElement('a'); $(cancel).addClass('cancel').attr({'href':'javascript:', 'title':'Cancel Changes'}).text('Cancel Changes'); cell.append(cancel); $(input).focus(); input.select(); } cancelUpdate this function just removes everything visible (all the dynamic junk in this case) in the cell and shows what used to be there. function cancelUpdate(){ var cell = $(this).parent(); cell.find(':visible').remove(); cell.find(':hidden').show(); } However, for some reason, the cancel link remains after it is clicked! Everything else is removed except that. W T F Thanks for any insight you're able to provide! I'm sure it's just some stupid little detail I'm over[caffeinatedly]looking... UPDATE Immediately after posting this I epiphanied that it may be a CSS issue, but after double checking my code, it is not.

  • add paddingRight just to specific column of flex grid

    - by Ben
    Whenever I add paddingRight to a column in the flex grid, it adds the padding to the header as well. Is anyone familiar with how I can add paddingRight just to the column and not to the header? Below is the column code where I was specifying the padding. <mx:DataGridColumn width="60" headerText="Type" dataField="Grade" headerStyleName="headerLeft" textAlign="left" draggable="false" resizable="false" headerRenderer="GridHeaderRenderer" paddingRight="5"/>

  • Issue with class template partial specialization

    - by DeadMG
    I've been trying to implement a function that needs partial template specializations and fallen back to the static struct technique, and I'm having a number of problems. template<typename T> struct PushImpl<const T&> { typedef T* result_type; typedef const T& argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ref) { // Code if the template is T& } }; template<typename T> struct PushImpl<const T*> { typedef T* result_type; typedef const T* argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ptr) { return PushImpl<const T&>::Push(sptr, *ptr); } }; template<typename T> struct PushImpl { typedef T* result_type; typedef const T& argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ref) { // Code if the template is neither T* nor T& } }; template<typename T> typename PushImpl<T>::result_type Push(typename PushImpl<T>::argument_type ref) { return PushImpl<T>::Push(this, ref); } First: The struct is nested inside another class (the one that offers Push as a member func), but it can't access the template parameter (StackSize), even though my other nested classes all could. I've worked around it, but it would be cleaner if they could just access StackSize like a normal class. Second: The compiler complains that it doesn't use or can't deduce T. Really? Thirdly: The compiler complains that it can't specialize a template in the current scope (class scope). I can't see what the problem is. Have I accidentally invoked some bad syntax?

  • Number of threads and thread numbers in Grand Central Dispatch

    - by raphgott
    I am using C and Grand Central Dispatch to parallelize some heavy computations. How can I get the number of threads used by GCD? Also is it possible to know on which thread a piece of code is currently running on? Basically I'd like to use sprng (parallel random numbers) with multiple streams and for that I need to know what stream id to use (and therefore what thread is being used).

  • Python: How efficient is subtring extraction?

    - by Cameron
    I've got the entire contents of a text file (at least a few KB) in string myStr. Will the following code create a copy of the string (less the first character) in memory? myStr = myStr[1:] I'm hoping it just refers to a different location in the same internal buffer. If not, is there a more efficient way to do this? Thanks!

  • Is there a compelling reason to use quantifiers in Perl regular expressions instead of just repeatin

    - by Morinar
    I was performing a code review for a colleague and he had a regular expression that looked like this: if ($value =~ /^\d\d\d\d$/) { #do stuff } I told him he should change it to: if ($value =~ /^\d{4}$/) { #do stuff } To which he replied that he preferred the first for readability (I find the second more readable, but that's a religious debate I'll save for another day). My question: is there an actual benefit to one over the other?

From my searches on the web everything seem to be OK. Any idea?

  • String searching algorithm for Chinese characters.

    - by Jack Low
    There are Python code available for existing algorithms for normal string searching e.g. Boyer-Moore Algorithm. I am looking to use this on Chinese characters and it doesn't seem like the same implementation would work. What would I go about doing in order to make the algorithm work on Chinese characters? I am referring to this: http://en.literateprograms.org/Boyer-Moore_string_search_algorithm_(Python)#References

  • C#: Exception to throw when a certain type was expected

    - by cbp
    I know this sort of code is not best practice, but nevertheless in certain situations I find it is a simpler solution: if (obj.Foo is Xxxx) { // Do something } else if (obj.Foo is Yyyy) { // Do something } else { throw new Exception("Type " + obj.Foo.GetType() + " is not handled."); } Anyone know if there is a built-in exception I can throw in this case?
