• Some good websites to learn about JavaScript and programming architecture?

  - by Jack Roscoe

  I'm not sure if 'architecture' is the correct term, but I've been looking for some articles online which talk about programming design and more about how best to use languages such as JavaScript in a code design sense rather than the actual syntax itself. I have found many websites but a lot seem to be very out dated, and I'm not sure what developments have taken place with JavaScript over the years so do not know how old is too old. If anybody could suggest some great websites, or maybe specific articles you think would be useful, that would be highly appreciated. I am a beginner programmer currently using JavaScript with XML and of course HTML & CSS, and I'm currently trying to get further into and learn more about web development.

• Is there a language designed for code golf?

  - by J S

  I am not really a fan of code golf, but I have to wonder, is there an esoteric language designed for it? I mean a language with following properties: Common programs may be expressed in very short amount of characters It uses ASCII character set effectively (for example, common operators are not identifiers, so they don't have to be separated by whitespace, character usage is distributed more or less evenly because we cannot use Huffman coding and so on) Except the terse syntax, it should have very expressible and clean semantics (like, let's say, Python or Scheme); it shouldn't be difficult to program in It doesn't need features for large scale programs, such as OOP, but it definitely should allow custom functions and data structures It should have a large standard library, identifiers in this library should be as short as possible Maybe it should be called CG? Languages that can be a source of inspiration are Forth, APL and Joy.

• Visual C++ 2008 doesn't recognize Windows declared types

  - by David Thornley

  I have a program that doesn't seem to recognize declared types in the latest U3D software. There's a line typedef BOOL (WINAPI* GMI)(HMON, LPMONITORINFOEX); which gets the error: Error 1 error C2061: syntax error : identifier 'LPMONITORINFOEX' c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 28 and a line MONITORINFOEX miMon; which gets Error 5 error C2065: 'miMon' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 Error 3 error C2065: 'MONITORINFOEX' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 The program's first non-comment statement is #include <windows.h>, which includes winuser.h, which defines these identifiers. In Visual Studio, I can right-click on them and go to the definition (a typedef) and from the typedef to the struct. WINAPI is defined in WinDef.h, so that seems to be working. There are no redefinitions of LPMONITORINFOEX or MONITORINFOEX in any other file. So, how can this be happening, and what can I do about it?

• Array in Bash Not Found

  - by Waffle

  I am trying to declare an array in bash, but when the code is run it says it cannot find the array. I have tried to write out the declaration of the array in several different ways, but it seems no matter how I try to declare it I cannot get it to work. I originally tried to declare it as such: candidate[1]= 0 candidate[2]= 0 candidate[3]= 0 The error messages that are returned are: votecalculation.sh: 13: candidate[1]=: not found votecalculation.sh: 14: candidate[2]=: not found votecalculation.sh: 15: candidate[3]=: not found After this I tried another solution I found online: ARRAY=( 'can1' 'can2' 'can3' ) When that is used it returns this error: votecalculation.sh: 12: Syntax error: "(" unexpected I am new to Bash and am getting really confused about arrays. Is there some specific way I need to declare an array or am I just going about it completely wrong?

• Crystal Report Function for converting Seconds to Timespan format.

  - by arakkots

  I have a crystal report where it shows the Agent's activities throughout the day with a pie chart. In the details section it is displaying: Activity [string] StartedAt [DateTime] EndedAt [DateTime] Duration [The difference between EndedAt and StartedAt in seconds - Integer] Report data is GroupedBy Activity and summarized by Duration. Currently Duration is shown in seconds but I need to format it 02h:30m:22s:15ms. For that I wrote a custom function in Crystal Report in the Formula Workshop editor as follows, but it looks like the syntax is not right (Error message on keyword Long: "A variable type (for example, 'String') is missing."). Can someone help? Function GetTimeSpanString(seconds as Long) Dim ts As TimeSpan = TimeSpan.FromSeconds( seconds ); GetTimeSpan = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds) End Function

• Disable page cache on a specific page

  - by David Brunelle

  Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

• How do I return the rows from an Oracle Stored Procedure using SELECT?

  - by Calanus

  I have a stored procedure which returns a ref cursor as follows: CREATE OR REPLACE PROCEDURE AIRS.GET_LAB_REPORT (ReportCurTyp OUT sys_refcursor) AS v_report_cursor sys_refcursor; report_record v_lab_report%ROWTYPE; l_sql VARCHAR2 (2000); BEGIN l_sql := 'SELECT * FROM V_LAB_REPORT'; OPEN v_report_cursor FOR l_sql; LOOP FETCH v_report_cursor INTO report_record; EXIT WHEN v_report_cursor%NOTFOUND; END LOOP; CLOSE v_report_cursor; END; I want to use the output from this stored procedure in another select statement like: SELECT * FROM GET_LAB_REPORT() but I can't seem to get my head around the syntax. Any ideas?

• Is there any short way to load data to the properties of a class, for each column name matching the properties of the class?

  - by Ugur Gümüshan

  I want to load data to an instance of an object using its constructor and I write $this->property=$row["colname"] each time for each property. the mysql_fetch_object function fetches the data as an object but I am not sure if the instance of an object can be assigned to some object from inside. othwerwise I would use __construct($object) { $this=$object; } //doesn't give any syntax error Maybe I should look into iteration of properties and use foreach($object as $key => $value) $value=$object[$key]; or can I assign like $this=$object; within the constructor?

• Can I assign a maven dependency to a specific repo?

  - by mds

  So I have several large projects that use up to 8 different external repos, all specified in settings.xml rather than in poms. A lot of our internal dependencies are snapshots, so this obviously causes a lot of checking for updates across several external repos, when they are all in our internal repo. So my question is, is there a way to setup a profile/filter or anything similar where I can ensure that an update will only be checked for in a specific repo(s)? This is all in the spirit of better/quicker builds. Thanks!

• UITableView loading before variables being set

  - by Sheehan Alam

  I have a label on a UITableView. When clicked it will refresh my tableview and set the top cell's height. When I am setting the cell height, I am checking if a certain variable is TRUE. If true it will show the large height, if false, the smaller height. At the time of cell height creation, my variable is always false. It is a member variable and its value is being set when the user clicks on the label. How can I make sure that the variable is set before the table refreshes?

• Accessing form's resources (resx file) from code

  - by kzen

  If I have a form Frm1.cs that is using some icons, images or other resources, these resources get stored in the form's resx file (Frm1.resx). My simple question is how do I access these resources from code? As a workaround I can store these resources in the Project resource file and they will be available via Properties.Resources.resourcename. However, similar syntax does not work for the resources stored in the form's resource file. While searching for a solution I have come across several references to ResourceManager class but was not able to find a way to use that to access the form's resources...

• How can I use linq to build an object from 1 row of data?

  - by Hcabnettek

  Hi All, I have a quick linq question. I have a stored proc that should return one row of data. I would like to use a lambda to build an object. Here's what I'm currently doing which works, but I know I should be able to use First instead of Select except I can't seem to get the syntax correct. Can anyone straighten me out here? Thanks for any help. var location = new GeoLocationDC(); DataSet ds = db.ExecuteDataSet(dbCommand); if(ds.Tables[0].Rows.Count == 1) { var rows = ds.Tables[0].AsEnumerable(); var x = rows.Select( c => new GeoLocationDC { Latitude = Convert.ToInt32(c.Field<string>("LATITUDE")), Longitude = Convert.ToInt32(c.Field<string>("LONGITUDE")) }).ToList(); if(x.Count > 0 ) { location = x[0]; } Cheers, ~ck }

• Help using the Office Interop for Word and Outlook 2007 in VB.NET

  - by vhorsen

  I need to start utilizing the interop in my programs to automate several functions in Word and Outlook and I was checking if anyone knew a good place to start. My ultimate goal is for my program to kick off a mail merge, create several different files and save them accordingly, then e-mail the different files to different people based upon who needs what. So any help on learning how to use the interop properly would be greatly appreciated. I am currently using Visual Studio 2008 and Office 2007 and use vb.net to write my programs. Thank you in advance.

• php database session handling problem in IE8!

  - by psyb0rg

  I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

• Conditional Regex Replace in C# without MatchEvaluator

  - by Buttink

  So, Im trying to make a program to rename some files. For the most part, I want them to look like this, [Testing]StupidName - 2[720p].mkv But, I would like to be able to change the format, if so desired. If I use MatchEvaluators, you would have to recompile every time. Thats why I don't want to use the MatchEvaluator. The problem I have is that I don't know how, or if its possible, to tell Replace that if a group was found, include this string. The only syntax for this I have ever seen was something like (?<group>:data), but I can't get this to work. Well if anyone has an idea, im all for it.

• MS SQL Server 2008 Stored Procedure Result as Column Default Value

  - by user337501

  First of all, thank you guys. You always know how to direct me when I cant even find the words to explain what the heck im trying to do. The default values of the columns on a couple of my tables need to equal the result of some complicated calculations on other columns in other tables. My first thought is to simply have the column default value equal the result of a stored procedure. I would also have one or more of the parameters pulled from the columns in the calling table. I don't know the syntax of how to do it though, and any time the word "stored" and "procedure" land next to each other in google I'm flooded with info on Parameter default values and nothing relating to what I actually want. Half of that was more of a vent than a question...any ideas though? And plz plz dont say "Well, you could use an On-Insert Trigger to..."

• Attaching user data to AXObserver

  - by Ben Packard

  I am using an AXObserver to monitor when a window is closed. In the callback, I am just raising an NSNotification. All working well. What is the correct syntax for attaching some user data as refcon? The working call looks like this: err6 = AXObserverAddNotification(observerTable, tableRef, kAXUIElementDestroyedNotification, nil); and the callback specified when I create the observer has the signature: static void cbTableClosed (AXObserverRef observer, AXUIElementRef element, CFStringRef notification, void *refcon) I want to replace refcon with an object of my own, but don't know how to change either line. The obvious objective-c type changes through up warnings.

• Cannot execute cut-n-paste VBScripts

  - by IcedDante

  I have been going mad trying to figure out why my scripts weren't working, until I started copying and pasting sample source code directly from a few websites only to have it fail there as well. I am getting the following error in my VBScripts: C:\temp\vbs\script.vbs(19, 53) Microsoft VBScript compilation error: Expected statement' For a line of code that looks like this: wdoc.Application.Selection.Find.Execute Replace:=wdReplaceAll This is interfacing with Microsft Word in Office 2007 to conduct a search and replace. Index 53 point directly to the := part of the assignment. Since this type of syntax doesn't work on my machine and I am using it from several websites, I was wondering if the cscript.exe I use is out of date. Am I not calling cscript properly?

• SQL Server Express 2008 Stored Procedure execution time spikes periodically

  - by user156241

  I have a big stored procedure on a SQL Server 2008 Express SP2 database that gets run about every 200 ms. Normal execution time is about 50ms. What I am seeing is large inconsistencies in this run time. It will execute for while, say 50-100 times at 40-60ms which is expected, then seemingly at random the same stored procedure will take way longer, say 900ms or 1.5 seconds to run. Sometimes more than one call of the same procedure in a row will take longer too. It appears that something is causing sql server to slow down dramatically every minute or so, but I can't figure out what. There is no timing pattern between the occurences. I have the same setup on two different computers, one of which is a clean XP Pro load with no virus checking and nothing installed except SQL server. Also, The recovery options for all the databases are set to "Simple".

• Can't get Angular Dart Router to work

  - by JesterXL

  I've tried this syntax in AngularDart 0.11.0: Angular Dart passing data from route service into a controller module.value(RouteInitializerFn, configureRoutes); void configureRoutes(Router router, RouteViewFactory views) { print("configureRoutes"); views.configure({ 'login': ngRoute( path: '/login', view: 'login/login.tpl.html'), 'today': ngRoute( path: '/today', view: '/today/today.tpl.html') }); However, my routing function never seems to get called. I've used both a print statement and breakpoint to no avail. When I attempt to call it like so: WorkoutLoggerApplication(this.rootScope, this.router) { print("WorkoutLoggerApplication::constructor"); new Future.delayed(new Duration(seconds: 2), () { router.go("login", {}); }); } I get: Bad state: Invalid route name: login I've tried 0.10.0, but no dice. I've also tried 3 varieties of the new bind function format, both also don't seem to ever fire the routing function.

• Why Could Linq to Sql Submit Changes Fail for Updates Despite Data in Change Set

  - by KevDog

  I'm updating a set of objects, but the update fails on a SqlException that says "Incorrect Syntax near 'Where'". So I crack open SqlProfiler, and here is the generated SQL: exec sp_executesql N'UPDATE [dbo].[Addresses] SET WHERE ([AddressID] = @p0) AND ([StreetAddress] = @p1) AND ([StreetAddress2] = @p2) AND ([City] = @p3) AND ([State] = @p4) AND ([ZipCode] = @p5) AND ([CoordinateID] = @p6) AND ([CoordinateSourceID] IS NULL) AND ([CreatedDate] = @p7) AND ([Country] = @p8) AND (NOT ([IsDeleted] = 1)) AND (NOT ([IsNonSACOGZip] = 1))',N'@p0 uniqueidentifier,@p1 varchar(15),@p2 varchar(8000),@p3 varchar(10),@p4 varchar(2),@p5 varchar(5),@p6 uniqueidentifier,@p7 datetime,@p8 varchar(2)',@p0='92550F32-D921-4B71-9622-6F1EC6123FB1',@p1='125 Main Street',@p2='',@p3='Sacramento',@p4='CA',@p5='95864',@p6='725E7939-AEE3-4EF9-A033-7507579B69DF',@p7='2010-06-15 14:07:51.0100000',@p8='US' Sure enough, no set statement. I also called context.GetChangeSet() and the proper values are in the updates section. Also, I checked the .dbml file and all of the properties Update Check values are 'Always'. I am completely baffled on this one, any help out there?

• In GWT-EXT checkboxtree how to handle single selection of tree nodes?

  - by RAS

  hi, I'm working on checkBoxTree in GWT-EXT 2.0.3 with Java. My aim is to get a selectionModel which allows me to select(check) only one TreeNode at a time. If I select another TreeNode after selecting one then, the previous one should be unchecked. I've tried using DefaultSelectionModel with TreePanel, but either I've not used it properly or it's working only for selection of TreeNode not for checking a TreeNode. Can anyone help me in this? Thanks in advance.

• Using XTemplate with SimpleStore in Ext

  - by qui

  I am currently adding some functionality to some old code. There used to be a template which took a flat array of items and spat out some HTML, now the data is coming from a simple store which reads some JSON.. var allwords = [ ['abacteriano', 'abacteriano'], ['abacterial', 'abacteriano'], ['abciximab', 'abciximab'], etc.. So my simplestore goes like this: termStore = new Ext.data.SimpleStore({ fields: ['term', 'lookup'], data: allwords }); This definitly works fine as I use the termStore in a combobox. However I am having difficulty getting it to play with an XTemplate. It seems the syntax in extjs doesn't play well with SO, so this bit wont be in a code block... So I guess I'll describe it :p Essentially its a simple template which tries to get values out of the passed collection by doing {term} I then try and apply it by doing: tpl.overwrite(Ext.get("contentbox"), termStore); This gives me a JS error of "invalid object initializer"

• How can I check a user/password combination on an ActiveDirectory without putting the password in a String?

  - by Jean Hominal

  I want to check User/Password combination on a Windows domain. Right now I do it with the following code: bool Login(String username, String password) { var principalContext = new PrincipalContext(ContextType.Domain); principalContext.ValidateCredentials(username, password); } While it works, the thing that bugs me is that I have to put the password in a String in order to use that API; as I am using a SecureString to store the password everywhere else, I would really like to use some way of checking the username / password combination without having to pass the password as a managed System.String. What would be the best way of achieving that?
