• What is the maximum number of controls that a VBA form can hold?

  - by Lunatik

  I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

• File IO, Handling CRLF

  - by aCuria

  Hi, i am writing a program that takes a file and splits it up into multiple small files of a user specified size, then join the multiple small files back again. 1) the code must work for c, c++ 2) i am compiling with multiple compilers. I am reading and writing to the files by using the stl functions fread() and fwrite() The problem I am having pertains to CRLF. If the file I am reading from contains CRLF, then I want to retain it when i split and join the files back together. If the file contains LF, then i want to retain LF. Unfortunately, fread() seems to store CRLF as \n (I think), and whatever is written by fwrite() is compiler-dependent. How do i approach this problem? Thanks.

• Advanced search functionality

  - by Chris

  I have a website with a jQuery based autocomplete search functionality which works great. Currently though I have just one search box for all categories, what I want is for someone to be able to type in, say for example, dorian gray dvd (in any order) which will search for dorian gray within the dvd category. What this will require then is a bit of magic on the server side to figure out if any of the words are category keywords, and then limit the search by that. What is the best (and quickest) way to do this in PHP / MySQL? I currently have a few trains of thought Search the category table for matches and perhaps order the results by that. Or split up the search terms into an array and separately search the categories for that for a match. Another thought I just had is to concat the category title to the dvd title in the database and match against that, or something similar... but this sounds computationally expensive? Any advice?

• Business Object desgin

  - by Dan

  I have a question about how I setup my BO's. I setup the BO's to contain all of my properties of the object as well as the business logic to satisfy the business rules. I decided to make all of the methods static, but I'm not sure if that was the right decision. Someone told me to split my BO's into an Entity Object of just properties and then a BO of just methods that do business rules, and don't make the methods static. Does anyone have some experience with the way i've set this up? Any examples of how it might work better for future growth? Thanks!

• PostgreSQL like + Hibernate problem

  - by Marat_Galiev

  Hi all. I want to do search in PostgreSQL for INTEGER based columns. if (!sSearch.isEmpty()) { sSearch = sSearch.replaceAll("[^a-zA-Z0-9]", "_").toLowerCase(); String[] search = sSearch.split(" "); sWhere = " "; for (NewsColumns column : NewsColumns.values()) { for (String s : search) { sWhere += "lower(" + column + "::TEXT) LIKE '%" + s + "%' OR "; } } sWhere = sWhere.substring(0,sWhere.length()-3); } Ok, I want to convert INT value to String before search, with '::TEXT' expression. But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.

• replacing text within quotes until next quote

  - by Jordan Trainor

  String input = "helloj\"iojgeio\r\ngsk\\"jopri\"gj\r\negjoijisgoe\"joijsofeij\"\"\"ojgsoij\""; This is my current code that works but iv added some code that has to run before this which makes some '"' split onto another line thus making the code below obsolute unless under certain cirumstances the '"' is not put onto the next line. firstQuote = input.IndexOf("\""); lastQuote = input.LastIndexOf("\""); input = input.Substring(0, firstQuote) + "<span>quote" + input.Substring(firstQuote + 1, lastQuote - (firstQuote + 1) + "quote</span>" + input.Substring(lastQuote + 1, lines.Length - (lastQuote + 1); How could I change the input string from input = "helloj\"iojgeio\r\ngsk\\"jopri\"gj\r\negjoijisgoe\"joijsofeij\"\"\"ojgsoij\""; to input = "helloj(<span>quoteiojgeio\r\ngsk\\"jopriquote</span>gj\r\negjoijisgoe<span>quotejoijsofeijquote</span>quote<span>quote</span>ojgsoij<span>quote</span>";

• string parsing help

  - by sprugman

  I've got a string like this: #################### Section One #################### Data A Data B #################### Section Two #################### Data C Data D etc. I want to parse it into something like: $arr( 'Section One' => array('Data A', 'Data B'), 'Section Two' => array('Data C', 'Data D') ) At first I tried this: $sections = preg_split("/(\r?\n)(\r?\n)#/", $file_content); The problem is, the file isn't perfectly clean: sometimes there are different numbers of blank lines between the sections, or blank spaces between data rows. The section head pattern itself seems to be relatively consistent: #################### Section Title #################### The number of #'s is probably consistent, but I don't want to count on it. The white space on the title line is pretty random. Once I have it split into sections, I think it'll be pretty straightforward, but any help writing a killer reg ex to get it there would be appreciated. (Or if there's a better approach than reg ex...)

• Rails/mysql SUM distinct records - optimization

  - by pepernik

  Hey. How would you optimize this SQL SELECT SUM(tmp.cost) FROM ( SELECT DISTINCT clients.id as client, countries.credits_cost AS cost FROM countries INNER JOIN clients ON clients.country_id = countries.id INNER JOIN clients_groups ON clients_groups.client_id=clients.id WHERE clients_groups.group_id IN (1,2,3,4,5,6,7,8,9) GROUP BY clients.id ) AS tmp; I'm using this example as part of my Ruby on Rails project. Note that my nested SQL (tmp) can have more then 10 milion records. You can split that in more SQLs if the performance is better. Should I add any indexes to make it quicker (i have it on IDs)?

• n-grams from text in PostgreSQL

  - by harshsinghal

  I am looking to create n-grams from text column in PostgreSQL. I currently split(on white-space) data(sentences) in a text column to an array. select regexp_split_to_array(sentenceData,E'\s+') from tableName Once I have this array, how do I go about: Creating a loop to find n-grams, and write each to a row in another table Using unnest I can obtain all the elements of all the arrays on separate rows, and maybe I can then think of a way to get n-grams from a single column, but I'd loose the sentence boundaries which I wise to preserve. Sample SQL code for PostgreSQL to emulate the above scenario create table tableName(sentenceData text); INSERT INTO tableName(sentenceData) VALUES('This is a long sentence'); INSERT INTO tableName(sentenceData) VALUES('I am currently doing grammar, hitting this monster book btw!'); INSERT INTO tableName(sentenceData) VALUES('Just tonnes of grammar, problem is I bought it in TAIWAN, and so there aint any englihs, just chinese and japanese'); select regexp_split_to_array(sentenceData,E'\s+') from tableName; select unnest(regexp_split_to_array(sentenceData,E'\s+')) from tableName;

• Loop colours from variables for graphics.py [Python 3.2]

  - by user1056548

  I am creating a graphics program that draws 100 x 100 squares next to each other depending on the user-specified grid size. The user also inputs 4 colours for the squares to be coloured (e.g. if they enter red,green,blue,yellow the squares will be coloured in that order, repeating the colours). Is it possible to loop the colours from the variables the user has given? Here is what I have so far: def main(): print ("Please enter four comma seperated colours e.g.: 'red,green,blue,yellow'\n\ Allowed colours are: red, green, blue, yellow and cyan") col1, col2, col3, col4 = input("Enter your four colours: ").split(',') win = GraphWin ("Squares", 500, 500) colours = [col1, col2, col3, col4] drawSquare (win, col1, col2, col3, col4, colours) win.getMouse() win.close() def drawSquare(win, col1, col2, col3, col4, colours): for i in range (4): for j in range (len(colours)): colour = colours[j] x = 50 + (i * 50) circle = Circle (Point (x,50), 20) circle.setFill(colour) circle.draw(win) I think I should be using a list in some way, but can't work out exactly how to do it. Can anybody help?

• Complicated conditional SQL query

  - by DevAno1

  I'm not even sure if it's possible but I need it for my Access database. So I have following db structure : Now I need to perform a query that takes category_id from my product and do the magic : - let's say product belongs to console (category_id is in table Console) - from console_types take type_id, where category_id == category_id - but if product belongs to console_game (category_id is in table console_game) - from console_game take game_cat_id, where category_id == category_id I'm not sure if mysql is capable of such thing. If not I'm really f&%ranked up. Maybe there is a way to split this into 2,3 separate queries ?

• JBoss classloading when 2 WARs have the same class

  - by Pacman

  I have a web applications A.war which has two servlets AServlet and BServlet. Both instantiate a helper class com.mycompany.Foo.class (this is my own class, not a third party library). Now I want to split the two servlets into two separate WARs: A.war will have only AServlet and a new B.war will have BServlet. AServlet will invoke BServlet via HTTP GET. Both WARs will have com.mycompany.Foo.class. I want to deploy both WARs on the same JBoss instance. The question is, will there be any classloading issues due to the same class being present in both WARs, and the WARs being deployed on the same JBoss instance?

• New to php and need to format a php page from html statement

  - by Peter D

  My problem is the page shows a vertical line of options. I want to put them into a 4 column table to display instead of just down lhs of page. The code I want to change is as follows: </tr> <tr> <td>{LOOP: JOBTYPE} IF("{JOBTYPE.parent_id}"!="0"){&nbsp; {:IF} IF("{JOBTYPE.catcount}"=="0"){<input type="checkbox" name="jobtype[{JOBTYPE.id}]" value="{JOBTYPE.id}" {JOBTYPE.selected}>{JOBTYPE.title}<br>{:IF} IF("{JOBTYPE.catcount}"!="0"){<strong>{JOBTYPE.title}</strong><br>{:IF} {/LOOP: JOBTYPE}</td> </tr> <tr> <td>&nbsp;</td> </tr> As you can see I have another column there and can split cell further but i would like the job list to be displayed accross the page not vertically. Thank you in advance, Peter

• Javascript / jQuery Exec turns up Null

  How do I skip over this next line if it turns out to be null? Currently, it (sometimes) "breaks" and prevents the script from continuing. var title = (/(.*?)<\/title/m).exec(response)[1]; $.get(url, function(response){ var title = (/<title>(.*?)<\/title>/m).exec(response)[1]; if (title == null || title == undefined){ return false; } var words = title.split(' '); $.each(words, function(index, value){ $link.highlight(value + " "); $link.highlight(" " + value); }); });

• ModX: Selecting and outputting specific menu items using Wayfinder

  - by Staffan Estberg

  tI've been trying to output specific menu items, also wanting to change the names of some, without satisfying results. The problem is that I have three different menu setups throughout the site - the header split into two sections and the footer divided into a couple of columns. This is what I've tried so far - [[Wayfinder? &startId=0 &level=1 &limit=5 &excludeDocs=49,61,55]] While it works excluding all the other links isn's the most optimal solution as there are 11 in total plus I want to be able to 1. rearrange the order and 2. change the names of two of them. Is this possible at all using the Wayfinder or do I have to create a snippet? Thanks in advance.

• Shared library to minimise size of FLA file

  - by Dmitry

  In a project we use large flash FLA file with lots of graphic assets, but the actual data that is changed is just in a few symbols. Sometimes it is not very efficient to transfer the whole FLA file that comes up to 20MB now. I was thinking about using Shared Libraries, but it seems that, even if you import external library, it still copies the whole assets into the destination file, but does not link it from external file. Consequently, size of the FLA file still remains the same. Is there any way to split FLA files into few separate in order to minimise size of the most frequently updated file and keep all unchanged data in another file?

• How do you store sets in Cassandra?

  - by Ben W

  I'd like to convert this JSON to a data model in Cassandra, where each of the arrays is a set with no duplicates: var data = { "data1": { "100": [1, 2, 3], "200": [3, 4] }, "data2": { "k1", [1], "k2", [4, 5] } } I'd like to query like this: data["data1"]["100"] to retrieve the sets. Anyone know how you might model this in Cassandra? (The only thing I came up with was columns whose name was a set value and the value of the column was an empty string, but that felt wrong.) It's not OK to serialize the sets as JSON or some other string, which would make this much easier. Also, I should note that it's OK to split data1 and data2 into separate ColumnFamilies, it's not necessary that they're keys in the same one.

• How can I extract just the elements I want from a Perl array?

  Hey I'm wondering how I can get this code to work. Basically I want to keep the lines of $filename as long as they contain the $user in the path: open STDERR, ">/dev/null"; $filename=`find -H /home | grep $file`; @filenames = split(/\n/, $filename); for $i (@filenames) { if ($i =~ m/$user/) { #keep results } else { delete $i; # does not work. } } $filename = join ("\n", @filenames); close STDERR; I know you can delete like delete $array[index] but I don't have an index with this kind of loop that I know of.

• Validating Column Data Stored as CSV Against Another Table

  - by Jakkwylde

  I wanted to see what some suggested approaches would be to validate a field that is stored as a CSV against a table containing appropriate values. Althought it would be desired, it is NOT an option to split the CSV list into another related table. In the example data below I would be trying to capture the code 99 for widget A. Below is an example data representation. Table: Widgets WidgetName WidgetCodeList A 1, 2, 3 B 1 C 2, 3 D 99 Table: WidgetCodes WidgetCode 1 2 3 An earlier approach was to query the CSV column as rows using various string manipulations and CONNECT_BY_LEVEL however the performance was not acceptible.
