  • stored procedure vs UDF

    - by TheObserver
    I have a select statement and in a couple of the fields, I want to check if an entry for the record exists in another table and if it does, output 1 value and if it doesn't, provide another value. What would be the best way to do it? When would you use a stored procedure and when would you use a UDF?

  • .net Class "is not a member of" Class .. even though it is?

    - by Matt Thrower
    Hi, Looking over some older code, I've run into a strange namespace error. Let's say I have two projects, HelperProject and WebProject. The full namespace of each - as given in application properties - is myEmployer.HelperProject and myEmployer.Web.WebProject. The pages in the web project are full of statements that use classes from the helper project. There are no imports/using statements but there is a reference to the helper project added in the bin. A few example lines might be: myEmployer.HelperProject.StringHelper.GetFixedLengthText(Text, "", Me.Width, 11) myEmploter.HelperProject.Utils.StringHelper.EstimatePixelLength(Text, 11) However every line that is written in this manner is throwing the error 'HelperProject' is not a member of 'myEmployer'. If you declare the statements like this: HelperProject.StringHelper.GetFixedLengthText(Text, "", Me.Width, 11) HelperProject.Utils.StringHelper.EstimatePixelLength(Text, 11) Everything seems fine. In the solution object browser and the bin folder, HelperProject appears with its full namespace, myEmployer.HelperProject. I don't want to have to change all the statements, and besides I suspect this is masking a more fundamental problem here. But I have no idea what's going on. Can anyone offer any pointers please? Cheers, Matt

  • Twitter search API VS Operators

    - by supermogx
    I've found this page about the Twitter search API and some operators : http://search.twitter.com/operators But is it possible to make a search like : All posts containing the words "ipod OR ipad" AND all posts containing the words "funny OR joke" ? Like : "happy AND hour" OR "ipod AND ipad" this doesn't look like it's possible.

  • Iframe vs dynamically loading web user controls

    - by kevin
    I need some advice on techniques to perform page redirect in asp.net. Which one is more recommended to use in asp.net? Dynamically changed the src of the Iframe to difference aspx. Dim frame As HtmlControl = CType(Me.FindControl("frameMain"), HtmlControl) frame.Attributes("src") = "page1.aspx" Dynamically load web user controls to an asp:panel. panelMain.Controls.Clear() panelMain.Controls.Add(LoadControl("WebControl/page1.ascx")) (convert all aspx page to web user controls)

  • ESRI frameworks: java vs javascript

    - by Luke
    I'm about to develop a web mapping application with ESRI Products like ArcGIS Server and Image Server. I can't find a good comparison between the Java Web ADF and the Javascript Framework. They're of course different because one is a full environment and the other is only client side but it's much more concise and the step to start is minimal. Another problem is that the Java Web ADF is not compatible with our current application server (JBoss 4.2.2) and require an old 4.0.2 version. Someone out there has experience that can help me? Many thanks.

  • html.erb vs erb (and haml equivalents)

    - by mathee
    I'm not sure I understand the difference between the html.erb files and erb files in the views for a Ruby on Rails application. (Similarly for haml files.) What are the dis/advantages of each (html.erb/haml or erb/haml) files? PS I'm not asking about the difference between the erb and haml files -- just appending the extension to an html file versus not appending it.

  • Scripting Languages vs. Compiled Languages for web development

    - by Austin Hyde
    Though I come from a purely PHP background on the web development side of programming, I have also spent much time with C# and C++ on the desktop. I don't really want to spark any flame wars, but: When should you use scripting languages over compiled languages for website development? (and vice versa) Just to clarify, for the sake of this question, I define a "scripting language" to mean an interpreted language like PHP, Python, or Ruby, and a "compiled language" to mean a strongly typed, compiled language like C#, C++, Java, or VB.

  • Cython Speed Boost vs. Usability

    - by zubin71
    I just came across Cython, while I was looking out for ways to optimize Python code. I read various posts on stackoverflow, the python wiki and read the article "General Rules for Optimization". Cython is something which grasps my interest the most; instead of writing C-code for yourself, you can choose to have other datatypes in your python code itself. Here is a silly test i tried, #!/usr/bin/python # test.pyx def test(value): for i in xrange(value): i**2 if(i==1000000): print i test(10000001) $ time python test.pyx real 0m16.774s user 0m16.745s sys 0m0.024s $ time cython test.pyx real 0m0.513s user 0m0.196s sys 0m0.052s Now, honestly, i`m dumbfounded. The code which I have used here is pure python code, and all I have changed is the interpreter. In this case, if cython is this good, then why do people still use the traditional Python interpretor? Are there any reliability issues for Cython?

  • Style vs. ControlTemplate

    - by plotnick
    is it possible to define resources in the style rather then using a template? <ListView.Resources > <Style TargetType="{x:Type ScrollBar}"> <Setter Property="Background" Value="Transparent" /> </Style> </ListView.Resources> How can I wrap this thing into: <Style TargetType="{x:Type ListView}"> </Style> ?

  • Python Sets vs Lists

    - by mvid
    In Python, which data structure is more efficient/speedy? Assuming that order is not important to me and I would be checking for duplicates anyway, is a Python set slower than a Python list?

  • Bubble sort algorithm implementations (Haskell vs. C)

    - by kingping
    Hello. I have written 2 implementation of bubble sort algorithm in C and Haskell. Haskell implementation: module Main where main = do contents <- readFile "./data" print "Data loaded. Sorting.." let newcontents = bubblesort contents writeFile "./data_new_ghc" newcontents print "Sorting done" bubblesort list = sort list [] False rev = reverse -- separated. To see rev2 = reverse -- who calls the routine sort (x1:x2:xs) acc _ | x1 > x2 = sort (x1:xs) (x2:acc) True sort (x1:xs) acc flag = sort xs (x1:acc) flag sort [] acc True = sort (rev acc) [] False sort _ acc _ = rev2 acc I've compared these two implementations having run both on file with size of 20 KiB. C implementation took about a second, Haskell — about 1 min 10 sec. I have also profiled the Haskell application: Compile for profiling: C:\Temp ghc -prof -auto-all -O --make Main Profile: C:\Temp Main.exe +RTS -p and got these results. This is a pseudocode of the algorithm: procedure bubbleSort( A : list of sortable items ) defined as: do swapped := false for each i in 0 to length(A) - 2 inclusive do: if A[i] > A[i+1] then swap( A[i], A[i+1] ) swapped := true end if end for while swapped end procedure I wonder if it's possible to make Haskell implementation work faster without changing the algorithm (there's are actually a few tricks to make it work faster, but neither implementations have these optimizations)

  • Including .Net Framework 3.5 SP1 in prerequisites for VS 2005 Setup Project

    - by joshrobb
    I have a problem. The thing is that I am using Visual Studio 2005 and .Net Framework 3.5 sp1. I have created the app and I want to have the .Net Framework prerequisite installed before however I can only select 2.0 . This wont go well since some columns in some of my grids will be arranged differently along with other problems. Is there any add-ins or something I can use to included .Net Framework 3.5 sp1 in my prerequisite list?

  • best practices - multiple functions vs single function with switch case

    - by Amit
    I have a situation where I need to perform several small (but similar) tasks. I can think of two ways to achieve this. First Approach: function doTask1(); function doTask2(); function doTask3(); function doTask4(); Second Approach: // TASK1, TASK2, ... TASK4 are all constants function doTask(TASK) { switch(TASK) { case TASK1: // do task1 break; case TASK2: // do task2 break; case TASK3: // do task3 break; case TASK4: // do task4 break; } } A few more tasks may be added in future (though the chances are rare. but this cannot be ruled out) Please suggest which of the two approaches (or if any other) is a best practice in such a situation.

  • "Access 2002 vs SQL Server 200*" as DB for sharepoint

    - by Jake
    I work with a team that has a sharepoint site currently runnning and its lists are linked to an access DB. My question is really on the investment level, what would be the reasons to upgrade DB to sharepoint if only a few 100 users access this site. Is there a real benefit to replacing the DB with a version of SQL Server, escpecially if about to replace Access 2002 with 2007 some day. I know SQL Server can handle more memory and traffic for more users, but I'm looking for more reasons than that if there are any.

  • Perl vs Python but with more style than normally

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

  • How to use Mobile Browser Definition File for a Phone vs SmartPhone seperation

    - by Denis Hoctor
    Hi all, I'm looking to revamp our mobile site with something simple for phones below the ambiguous smart phone category and something a little more interesting for the phones above this category. I'm not interested in WAP/WML for this project. I'm building a ASP.Net 4 MCV 2 app and using MBDF What I'd like to know is how best to define this differentiation when using MBDF? Screen size, Javascript, SpportsTouchScreen etc. are all in MBDF along with others but I'm not sure where to draw the line and where the data is most accurate for the broad number of devices. What do those of you out there developing for this spread of hardware & software split on? Thanks, Denis P.S. I've done my research on xHTML MP1.0 - 1.2 and the best practises for implementation to ensure broad coverage but I don't want to restrict the newer phones out there to what the base line can see.

  • Mix Enviroment Debugging ( C# Fortran) in VS 2008

    - by Ngu Soon Hui
    I have two visual studio projects, one written in C#, another written in fortran unmanaged code ( Intel Fortran compiler). Both of them are attached to one solution. The C# is the frontend winform, whereas the fortran project is the backend. Is there any tutorials that teach on how to step into code direct from C#?

  • Delphi, PGDac vs Zeos, Fetch, Lookup?

    - by durumdara
    Hi! I used Zeos to test to know: is ZTable uses fetch technics, or not? May in the future we migrate our lesser system to PGSQL, and this used now "Table" components (as BDE, but it have an SQL-like server). These tables use real cursors, a "Window" with N record, so lookup is very fast, because the Locate/Lookup is started on server, and only these N records are refreshed, no matter, how many records in the lookup table. PGSQL uses fetch technics as I know, and I tested it with a table (id int, name varchar(100)), and 1 million records. (I also trying this with mysql). The adapter is Zeos. ID, sec to find, allocated memory in bytes on client. MySQL 500000 2,761 113 196 344 1000000 3,214 225 471 232 313800 0,437 225 471 232 328066 0,468 225 471 232 276374 0,390 225 471 232 905984 1,264 225 471 232 260253 0,359 225 471 232 PGSQL 500000 3,042 113 188 184 1000000 3,744 225 463 064 313800 0,436 225 463 064 328066 0,452 225 463 064 276374 0,375 225 463 064 905984 1,295 225 463 064 260253 0,359 225 463 064 142023 0,203 225 463 064 As you see the records are fetched locally, this cause the 225 MB usage, and searches are slow a little, based where is the record we must find. I want to ask more things: a.) Is PGDAC have some technics to we can use the lookups without pay the fetch with memory and secs? b.) Or is PG ODBC driver can help in this problem with ADO? (As I know ADO can use server side cursors)? c.) Have anybody some experience with lookup tables, and performance? Is this critical question or it is not? (With client memory usage too). d.) If no chance to avoid fetch hell with lookups, what we can do? Server Side Joins, and unique code for Lookup field changing without real Lookup? Thanks for your help: dd

  • VS 2008 designer and usercontrol.

    - by Ram
    Hello, I have created a custom data grid control. I dragged it on windows form and set its properties like column and all & ran the project. It built successfully and I am able to view the grid control on the form. Now if i try to view that form in designer, I am getting following error.. Object reference not set to an instance of an object. Instances of this error (1) 1.

However I can see the code for the grid in the designer file. Any pointer on this would be a great help. I have customized grid for my custom requirements like I have added custom text box n all. I have defined 3 constructors public GridControl() public GridControl(IContainer container) protected GridControl(SerializationInfo info, StreamingContext context)
