• Variable number of arguments in ParamArray ArgList()

  - by Excel VBA guy

  If I want to pass a number of values for the ParamArray arglist via an array, how do I do it? From what I've read so far, on VBA, it appears that I need to explicitly list the values that I want to pass. But what if there are potentially different numbers of values to pass, so I do not know in advance how many I'll want to pass to the function? Is there not some way of using an array (a one-dimensional array) with a variable dimension?

• Where to store application global variable?

  - by Shawn Mclean

  I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.

• xsl:variable contains nodeset. How to output nth node of variable?

  - by dnagirl

  I am transforming an XML document. There is an attribute @prettydate that is a string similar to "Friday, May 7, 2010". I want to split that string and add links to the month and the year. I am using the exslt:strings module and I can add any other necessary EXSLT module. This is my code so far: <xsl:template match="//calendar"> <xsl:variable name="prettyparts"> <xsl:value-of select="str:split(@prettydate,', ')"/> </xsl:variable> <table class='day'> <thead> <caption><xsl:value-of select="$prettyparts[1]"/>, <a> <xsl:attribute name='href'><xsl:value-of select="$baseref"/>?date=<xsl:value-of select="@highlight"/>&amp;per=m</xsl:attribute> <xsl:value-of select='$prettyparts[2]'/> </a> <xsl:value-of select='$prettyparts[3]'/>, <a> <xsl:attribute name='href'><xsl:value-of select="$baseref"/>?date=<xsl:value-of select="@highlight"/>&amp;per=y</xsl:attribute> <xsl:value-of select='$prettyparts[4]'/> </a> </caption> <!--etcetera--> I have verified, by running $prettyparts through a <xml:for-each/> that I am getting the expected nodeset: <token>Friday</token> <token>May</token> <token>7</token> <token>2010</token> But no matter which way I attempt to refer to a particular <token> directly (not in a foreach) I get nothing or various errors to do with invalid types. Here's some of the syntax I've tried: <xsl:value-of select="$prettyparts[2]"/> <xsl:value-of select="$prettyparts/token[2]"/> <xsl:value-of select="exsl:node-set($prettyparts/token[2])"/> <xsl:value-of select="exsl:node-set($prettyparts/token)[2]"/> Any idea what the expression ought to be?

• Contains performs MUCH slower with variable vs constant string MS SQL Server

  - by Greg R

  For some unknown reason I'm running into a problem when passing a variable to a full text search stored procedure performs many times slower than executing the same statement with a constant value. Any idea why and how can that be avoided? This executes very fast: SELECT * FROM table WHERE CONTAINS (comments, '123') This executes very slowly and times out: DECLARE @SearchTerm nvarchar(30) SET @SearchTerm = '123' SET @SearchTerm = '"' + @SearchTerm + '"' SELECT * FROM table WHERE CONTAINS (comments, @SearchTerm) Does this make any sense???

• Javascript - Do I need to use 'var' when reassigning a variable defined in the function's parameters

  - by John Himmelman

  I've found many definitions of the 'var' statement but most of them are incomplete (usually from introductory guides/tutorials). Should I use 'var' if the variable & scope has been declared in the params list? someFunc = function(someVar) { // Is it considered good practice to use 'var', even if it is redundant? var someVar = cheese; };

• node.js callback getting unexpected value for variable

  - by defrex

  I have a for loop, and inside it a variable is assigned with var. Also inside the loop a method is called which requires a callback. Inside the callback function I'm using the variable from the loop. I would expect that it's value, inside the callback function, would be the same as it was outside the callback during that iteration of the loop. However, it always seems to be the value from the last iteration of the loop. Am I misunderstanding scope in JavaScript, or is there something else wrong? The program in question here is a node.js app that will monitor a working directory for changes and restart the server when it finds one. I'll include all of the code for the curious, but the important bit is the parse_file_list function. var posix = require('posix'); var sys = require('sys'); var server; var child_js_file = process.ARGV[2]; var current_dir = __filename.split('/'); current_dir = current_dir.slice(0, current_dir.length-1).join('/'); var start_server = function(){ server = process.createChildProcess('node', [child_js_file]); server.addListener("output", function(data){sys.puts(data);}); }; var restart_server = function(){ sys.puts('change discovered, restarting server'); server.close(); start_server(); }; var parse_file_list = function(dir, files){ for (var i=0;i<files.length;i++){ var file = dir+'/'+files[i]; sys.puts('file assigned: '+file); posix.stat(file).addCallback(function(stats){ sys.puts('stats returned: '+file); if (stats.isDirectory()) posix.readdir(file).addCallback(function(files){ parse_file_list(file, files); }); else if (stats.isFile()) process.watchFile(file, restart_server); }); } }; posix.readdir(current_dir).addCallback(function(files){ parse_file_list(current_dir, files); }); start_server(); The output from this is: file assigned: /home/defrex/code/node/ejs.js file assigned: /home/defrex/code/node/templates file assigned: /home/defrex/code/node/web file assigned: /home/defrex/code/node/server.js file assigned: /home/defrex/code/node/settings.js file assigned: /home/defrex/code/node/apps file assigned: /home/defrex/code/node/dev_server.js file assigned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js For those from the future: node.devserver.js

• Pass a variable into a trigger

  - by Codesleuth

  I have a trigger which deals with some data for logging purposes like so: CREATE TRIGGER trgDataUpdated ON tblData FOR UPDATE AS BEGIN INSERT INTO tblLog ( ParentID, OldValue, NewValue, UserID ) SELECT deleted.ParentID, deleted.Value, inserted.Value, @intUserID -- how can I pass this in? FROM inserted INNER JOIN deleted ON inserted.ID = deleted.ID END How can I pass in the variable @intUserID into the above trigger, as in the following code: DECLARE @intUserID int SET @intUserID = 10 UPDATE tblData SET Value = @x PS: I know I can't literally pass in @intUserID to the trigger, it was just used for illustration purposes.

• Multiple dynamic method calls or declaring a variable in Grails

  - by user303979

  In my view, if I have a situation where I need to use a dynamic method (such as Domain.findByName("name")) in multiple places, would it be better to define a variable with and refer to that, rather than have the dynamic method in multiple places? I know this seems like an obvious answer, but I just wanted to make sure Grails doesn't cache it or something, and indeed two DB calls are being made.

• Add $PATH variable via Cocoa App

  - by golfromeo

  I'm trying to write a Cocoa app that makes it easier for Android developers on Macs to create Android apps. When a user presses a button on the app, I want it to add a certain directory to the environmental $PATH variable on the Mac. Is there another way to do this via Cocoa instead of opening up the .bash_profile file and adding the path manually? Thanks for any help in advance.

• Fortran: output format dependent on a variable

  - by Flux Capacitor

  I would like to have a FORTRAN write statement formatted to depend on some variable. For example, I could write: write(*,'(3f15.3,3f9.2)') x,y,z,(var(i),i=1,nvari) where nvari = 3 But, what if, in some cases, I actually have 4 variables (i.e. nvari = 4) I would like to write something like this: write(*,'(3f15.3,nvari(f9.2))') x,y,z,(var(i),i=1,nvari) Now, nvari can be anything and the output will work as I like. How can I make something like this work?

• Setting windows powershell path variable

  - by Vasil

  So I've found out that setting the PATH environment variable affects only the old command prompt, powershell seems to have different environment settings. How do I change the environment variables for powershell (v1)? Note: I want to make my changes permanent, so I don't have to set it every time I run powershell. Does powershell have a profile file? Something like bash profile on unix?
