• VS2005 SQL Syntax highlighting is incorrect for nested comments?

  - by MattH

  I'm working with VS2005, and SSMS 2005. SQL Server allows nested comments as follows: /* Comment 1 /* Comment 2 */ Some commented out code here */ This code runs fine. However if putting the above into a .sql file in VS2005, it incorrectly shows the commented out code as 'active', (its not green). It seems that StackOverflow has highlighted the code in the same way. Is this a bug in VS2005? Or does SSMS handle nested comments differently compared to the ANSI SQL standards? Can someone clarify this discrepancy, and if it appears to be a bug, if there a way to fix the syntax highlighting?

• how to tackle a custom forms database

  - by Neil Hickman

  I'm currently researching a project for the place that I work in. We are trying to create a system that will allow forms to be set up dynamically from a database. My question is what database structure would best suit something like this? I currently have a structure of: forms_form forms_formfields forms_formdata I don't think this is the most appropriate layout for this. Basically to make is make sense I need to be able to make a form within the database that can have infinite fields all customized and have the data when submitted stored in the database.

• Can a binary tree or tree be always represented in a Database table as 1 table and self-referencing?

  - by Jian Lin

  I didn't feel this rule before, but it seems that a binary tree or any tree (each node can have many children but children cannot point back to any parent), then this data structure can be represented as 1 table in a database, with each row having an ID for itself and a parentID that points back to the parent node. That is in fact the classical Employee - Manager diagram: one boss can have many people under him... and each person under him can have n people under him, etc. This is a tree structure and is represented in database books as a common example as a single table Employee.

• Visual Studio 2008 compiles anything in C++ file?

  - by Brad Pepers

  I noticed today that a source code file in a project was compiling even though it had junk at the top of it. It got me wondering what all would pass without error through the compiler. Here is an example of code that will not generate any error messages: what kind of weird behaviour is this??? #include "stdafx.h" // what is up? int foo(int bar) { bla bla bla????? return bar; } and more junk??? What in the world is the compiler doing to allow this code to compile without giving any error messages? I'm using Visual Studio 2008 and this is unmanaged C++ code. The foo function isn't actually generated in the object file so it can't be used but why no errors???

• How do I move the location of an xcodeproj file without breaking external build target?

  - by petFoo

  I have an Xcode project with a directory structure like this: MasterProjectDir/projectname.xcodeproj MasterProjectDir/ProjectSubDir/whatever.c MasterProjectDir/ProjectSubDir/etc.c MasterProjectDir/ProjectSubDir/Makefile My xcodeproj uses an external build target to point to the Makefile using these settings: Build Tool: /usr/bin/make Arguments: $(ACTION) Directory: ./ProjectSubDir For various reasons, I need to change the project directory structure to look like this: MasterProjectDir/projectname.xcodeproj MasterProjectDir/whatever.c MasterProjectDir/etc.c MasterProjectDir/Makefile I copied the .xcodeproj file into the ProjectSubDir and the project somehow still knows where to look for the files (?!?! - this is odd because their location is set as "relative to group" and I've just moved the xcodeproj file). It won't build. I get the following error: make: * No targets specified and no makefile found. Stop. Command /usr/bin/make failed with exit code 2 I could use a little help on this. There must be a setting I need to change somewhere.

• How do you keep application logic separate from UI when UI components have built-in functionality?

  - by Al C

  I know it's important to keep user interface code separated from domain code--the application is easier to understand, maintain, change, and (sometimes) isolate bugs. But here's my mental block ... Delphi comes with components with methods that do what I want, e.g., a RichText Memo component lets me work with rich text. Other components, like TMS's string grid not only do what I want, but I paid extra for the functionality. These features put the R in RAD. It seems illogical to write my own classes to do things somebody else has already done for me. It's reinventing the wheel [ever tried working directly with rich text? :-) ] But if I use the functionality built into components like these, then I will end up with lots of intermingled UI and domain code--I'll have a form with most of my code built into its event handlers. How do you deal with this issue? ... Or, if I want to continue using the code others have already written for me, how would you suggest I deal with the issue?

• Browser gets blocked, workers to the rescue?

  - by tb_selleo

  Hello, I use JavaScript for rendering 20 tables of 100 rows each. The data for each table is provided by controller as JSON. Each table is split into section that have "totals" and have some other JavaScript logic code. Some totals are outside of the table itself. As a result JavaScript blocks browser for a couple of seconds (especially in IE6) :( I was consideting to use http://code.google.com/p/jsworker/, however Google Gears Workers (I guess workers in general) will not allow me to make changes to DOM at the worker code, and also it seems to me that I can not use jQuery inside jsworker worker code. (Maybe I am wrong here?). This issue seems to be fundamental to the JavaScript coding practice, can you share with me your thoughts how to approach it?

• n how to show cascade windows in Splitcontainer panel2 c#

  - by user1875373

  In MdiParent toolstripmenuItem, I'm writing the code to show all the windows in cascade or Tile Horizontal style. My code is: this.LayoutMdi(MdiLayout.Cascade); this.LayoutMdi(MdiLayout.TileHorizontal); This code will work in mdi parent only. But now I'm using a Split container in my Parent Form. In Panel1 I have buttons to Show the Form. In Panel2 My Forms will display, as: Forms.paymentPaid paidFm = new SalesandPurchases.Forms.paymentPaid(); paidFm.MdiParent = this; paidFm.Left = (this.myPanel.Width - paidFm.Width) / 2; paidFm.Top = (this.myPanel.Height - paidFm.Height) / 2; myPanel.Controls.Add(paidFm); paidFm.Show(); Now Because of my Split Container my code( this.LayoutMdi(MdiLayout.Cascade)) is not working for cascade the windows in Panel2. Please tell me any other way.

• What's the scope of a Python variable declared in an if statement?

  - by froadie

  I'm new to Python, so this is probably a simple scoping question. The following code in a Python file (module) is confusing me slightly: if __name__ == '__main__': x = 1 print x In other languages I've worked in, this code would throw an exception, as the x variable is local to the if statement and should not exist outside of it. But this code executes, and prints 1. Can anyone explain this behavior? Are all variables declared in a module global/available to the entire module?

• Problem with dynamically added script element - attribute src is empty

  - by Stazh

  Hi there, I have a problem with dynamically added script element (using jQuery). Code for adding new script element to DOM is this: var pScript = document.createElement("script"); pScript.type = "text/javascript"; pScript.src = sFile; // Add element to the end of head element $("head").append(pScript); The script is added with no problem, and the code runs perfectly. But, the problem occurs when I try to find the newly added script. I use this code to iterate through all script elements: var bAdd = true; $("script").each(function() { if(this.src == sFile) bAdd = false; }); (I need this code to prevent adding script that is already loaded) Problem is that all other script elements have src attribute set, but the newly added (dynamically) has not... Any idea?

• More efficient R / Sweave / TeXShop work-flow?

  - by user594795

  I've now got everything to work properly on my Mac OS X 10.6 machine so that I can create decent looking LaTeX documents with Sweave that include snippets of R code, output, and LaTeX formatting together. Unfortunately, I feel like my work-flow is a bit clunky and inefficient: Using TextWrangler, I write LaTeX code and R code (surrounded by <<= above and @ below R code chunk) together in one .Rnw file. After saving changes, I call the .Rnw file from R using the Sweave command Sweave(file="/Users/mymachine/Documents/Assign4.Rnw", syntax="SweaveSyntaxNoweb") In response, R outputs the following message: You can now run LaTeX on 'Assign4.tex' So then I find the .tex file (Assign4.tex) in the R directory and copy it over to the folder in my documents ~/Documents/ where the .Rnw file is sitting (to keep everything in one place). Then I open the .tex file (e.g. Assign4.tex) in TeXShop and compile it there into pdf format. It is only at this point that I get to see any changes I have made to the document and see if it 'looks nice'. Is there a way that I can compile everything with one button click? Specifically it would be nice to either call Sweave / R directly from TextWrangler or TeXShop. I suspect it might be possible to code a script in Terminal to do it, but I have no experience with Terminal. Please let me know if there's any other things I can do to streamline or improve my work flow.

• How to change the meaning of pointer access operator

  - by kumar_m_kiran

  Hi All, This may be very obvious question, pardon me if so. I have below code snippet out of my project, #include <stdio.h> class X { public: int i; X() : i(0) {}; }; int main(int argc,char *arv[]) { X *ptr = new X[10]; unsigned index = 5; cout<<ptr[index].i<<endl; return 0; } Question Can I change the meaning of the ptr[index] ? Because I need to return the value of ptr[a[index]] where a is an array for subindexing. I do not want to modify existing source code. Any new function added which can change the behavior is needed. Since the access to index operator is in too many places (536 to be precise) in my code, and has complex formulas inside the index subscript operator, I am not inclined to change the code in many locations. PS : 1. I tried operator overload and came to conclusion that it is not possible. 2. Also p[i] will be transformed into *(p+i). I cannot redefine the basic operator '+'. So just want to reconfirm my understanding and if there are any possible short-cuts to achieve. Else I need fix it by royal method of changing every line of code :) .

• Confusion in bind call in socket programming

  - by Tarun

  i was learning socket programming in unix using c/c++. I am confused with one function call bind(params..). Actually it takes the adreess structure "sockaddr_in" and we can create the structure in the following way sockaddr_in.*** = somthing.. sockaddr_in..s_addr htonl(INADDR_ANY) **Passing INADDR_ANY will alow to bind all local addresses** My question is , why do we need to use "INADDR_ANY" ? In my knowledge every machine can has only one unique IP Address. In this way there is only one address associated with the machien. Thye bind call should directly bind the socket to the single available address. Please explain what are the different scenarios and why is it so?

• How do you redirect a standard stream of a C++ routine wrapped with SWIG and exposed to Python?

  - by cmdev

  Is it possible to control the standard streams of C++ code in python? The code is wrapped with SWIG and then exposed to Python where I call one of its functions. I am getting all kinds of unwanted messages coming from C++ code and I want to suppress them either by not using the output stream or by redirecting it to a bit bucket, e.g. devnull from the os module.

• Is there a way to log every gui event in Delphi?

  - by awmross

  The Delphi debugger is great for debugging linear code, where one function calls other functions in a predictable, linear manner, and we can step through the program line by line. I find the debugger less useful when dealing with event driven gui code, where a single line of code can cause new events to be trigerred, which may in turn trigger other events. In this situation, the 'step through the code' approach doesn't let me see everything that is going on. The way I usually solve this is to 1) guess which events might be part of the problem, then 2) add breakpoints or logging to each of those events. The problem is that this approach is haphazard and time consuming. Is there a switch I can flick in the debugger to say 'log all gui events'? Or is there some code I can add to trap events, something like procedure GuiEventCalled(ev:Event) begin log(ev); ev.call(); end The end result I'm looking for is something like this (for example): FieldA.KeyDown FieldA.KeyPress FieldA.OnChange FieldA.OnExit FieldB.OnEnter This would take all the guesswork out of Delphi gui debugging. I am using Delphi 2010

• How to count new lines in Internet Explorer?

  - by Impirator

  Hey, all. I'm doing my own syntax highlighter for Javascript and CSS, and I've run into an issue with Internet Explorer (big surprise). I grab all the contents of a code.block tag (example below) using innerHTML, and .split("\n") that result to get each line by itself. This works wonderfully except in IE. I have tried using innerText and .split("\r\n") also without success. Can anyone recommend a solution? If it makes a difference, my code.block tags are styled to be white-space:pre-wrap. <code class="block css">div#randomBarsDemo { width:175px; height:200px; } div#randomBarsDemo div { background-color:#111; width:100%; }</code>

• Load different views depending on the category of data on tap of tableview cell iPhone sdk

  - by neha

  Hi all, In my aplication, I want a tableview with different cell structure depending upon the category of data that's getting loaded in it [I have different categories like video, editorial etc with different structure of data like video has a single label, editorial has 3 labels etc]. I can load different nib files based on the data coming from xml parser. Now when the cell is tapped, I want to show its detailed view on a new viewController. So my question is is it possible to use only 1 viewController show different fields depending upon the category of data in the cell. Or do I need to create different viewControllers for each of the categories?

How do i configure it with structure map? protected void ConfigureDependencies() { ObjectFactory.Initialize( x => { x.For<ILogger>().Use<Logger>(); x.For<IRepository<T>>().Use<NHibernateRepository<T>>(); } ); } I m getting an error on T. Another question I have is if it s OK to make an ApplicationContext static class, configure it with structure map and provide instances with it? I have read that static classes are bad, but I dont want to initialize the ApplicationContext class that I have the injections everywhere. What s the best practice for this? Thanks.

• Is my program taking too much time to execute?

  - by Conrad C

  I wanted to solve a question from project euleur about finding the largest prime number of a big number. I run my code on a virtual machine on Visual studio 2012, and the code seems froze. When I step into the loop, the code works well, but when I execute it, the console is always there. It is as if the program is still running. Could it be that the program takes time to execute? My Code static void Main(string[] args) { long number = 5; for (long i = 1; i < 600851475143; i++) { if (i % 2 != 0 && i % 1 == 0 && i % i == 0) number = i; } }
