• vba excel copy subtable from sheet to sheet

  - by user429400

  I realize that this is probably a duplicate, but I've been searching for an hour and I can't to get the syntax right. I have a sheet with several tables. There is at least one empty column and one empty row between one table to the other. I know the start row and start column of each table, and I know that each table has 3 columns. I don't know how many rows it has. I want to write a sub that receives: table start row table start column and copies the table into another sheet (let's say that the destination is sheet2 starting at A1). I know I can do it with a loop, but I suspect there is a better syntax right? (The main issue here is that I need to find the number of rows each table has) Thanks. Li

• Storing object as a column in LINQ

  - by Alex

  Hello, i have some class which constructs itself from string, like this: CurrencyVector v = new CurrencyVector("10 WMR / 20 WMZ"); it's actually a class which holds multiple currency values, but it does not matter much. I need to change type of column in my LINQ table (in vs 2010 designer) from String to that class, CurrencyVector. If i do it - i get runtime error when LINQ runtime tries to cast String as CurrencyVector (when populating the table from database). Adding IConvertible did not help. I wrapped these columns in properties, but it's ugly and slow solution. Searching internet gave no results.

• Hibernate multi column discriminator

  - by shikarishambu

  I have a single lookup table that manages all lookups - legacy and new lookup table structure is context,name, code, value context is either legacy or new name is the name of the lookup - state, status etc...for example code is the code and value is the value associated with the code Is there a way to specify multiple columns as discriminators so that I can get all legacy state code/values or all new status code/values. Is there a different way to do this if discriminators cannot do it? <class name="com.company.domain.Lookup"> <id name="Id" column="id" type="big_integer"> <generator class="org.hibernate.id.TableHiLoGenerator" /> </id> <discriminator column="context" insert="false" /> <property name="code" type="string"/> <property name="value" type="string"/> <property name="desc" type="string"/> <subclass name="com.company.domain.LegacyLookup" discriminator-value="legacy">

• 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.

• Interpolating data points in Excel

  - by Niels Basjes

  Hi, I'm sure this is the kind of problem other have solved many times before. A group of people are going to do measurements (Home energy usage to be exact). All of them will do that at different times and in different intervals. So what I'll get from each person is a set of {date, value} pairs where there are dates missing in the set. What I need is a complete set of {date, value} pairs where for each date withing the range a value is known (either measured or calculated). I expect that a simple linear interpolation would suffice for this project. If I assume that it must be done in Excel. What is the best way to interpolate in such a dataset (so I have a value for every day) ? Thanks. NOTE: When these datasets are complete I'll determine the slope (i.e. usage per day) and from that we can start doing home-to-home comparisons. ADDITIONAL INFO After first few suggestions: I do not want to manually figure out where the holes are in my measurement set (too many incomplete measurement sets!!). I'm looking for something (existing) automatic to do that for me. So if my input is {2009-06-01, 10} {2009-06-03, 20} {2009-06-06, 110} Then I expect to automatically get {2009-06-01, 10} {2009-06-02, 15} {2009-06-03, 20} {2009-06-04, 50} {2009-06-05, 80} {2009-06-06, 110} Yes, I can write software that does this. I am just hoping that someone already has a "ready to run" software (Excel) feature for this (rather generic) problem.

• Getting Started with Fluent NHibernate

  - by Andy

  I'm trying to get into using Fluent NHibernate, and I have a couple questions. I'm finding the documentation to be lacking. I understand that Fluent NHibernate / NHibernate allows you to auto-generate a database schema. Do people usually only do this for Test/Dev databases? Or is that OK to do for a production database? If it's ok for production, how do you make sure that you're not blowing away production data every time you run your app? Once the database schema is already created, and you have production data, when new tables/columns/etc. need to be added to the Test and/or Production database, do people allow NHibernate to do this, or should this be done manually? Is there any REALLY GOOD documentation on Fluent NHibernate? (Please don't point me to the wiki because in following along with the "Your first project" code building it myself, I was getting run-time errors because they forget to tell you to add a reference. Not cool.) Thanks, Andy

• iPad javascript scrolling

  - by davids

  I'd like to get the same behaviour of the native javascript scrollTo function in iPad, just attaching a function to the swipe event and scrolling the content a specific number of pixels. That doesn't work in iPad using scrollTo or several different jquery plugins, like scrollTo or iScroll. I think I'm having problems because I'm working with an iframe, as I have another html document in it, with its body divided in columns, but I'm just showing the first one. The point of all this is that, after swiping, it should show the next/prev column, and I tried scrolling the iframe window or the inner's html body, which actually works in chrome, but it doesn't in iPad.

• Using SQL to get the Last Reply on a Post

  - by Anraiki

  I am trying to replicate a forum function by getting the last reply of a post. For clarity, see PHPBB: there are four columns, and the last column is what I like to replicate. I have my tables created as such: discussion_id (primary key) user_id parent_id comment status pubdate I was thinking of creating a Link Table that would update for each time the post is replied to. The link table would be as follow: discussion_id (primary key) last_user_id last_user_update However, I am hoping that theres a advance query to achieve this method. That is, grabbing each Parent Discussion, and finding the last reply in each of those Parent Discussions. Am I right that there is such a query?

• gridview dropbox

  - by tbischel

  I'm trying to use a GridView to display a list of components in ASP.NET. I'm trying to make it editable at the same time. One of the columns is a string that should be selected out of a list when the user edits the row. So I've tried the following: Convert the BoundField row to an ItemTemplate Add a dropbox to the template window in the gridview bound the selecteditem to the string At this point, I get an error because the list items haven't been set up in the dropbox. So I guess the two things I'm wondering are: How do I assign the items in the dropbox to a dynamically created list of options? How do I make the dropbox only appear when the row is being edited?

• which is better, creating a materialized view or a new table?

  - by Carson

  I have some demanding mysql queries that are needed to grap same up-to-date datasets from 5-7 mysql tables. I am thinking of creating a table or materialized view to gather all demanding columns from other tables, so as to increase performance. If I create that table, I may need to do extra insert / update / delete operation each time other tables updated. if I create materialized view, I am worrying if the performance can be greatly improved. Because data from other tables are changing very frequently. Most likely, the view may need to be created first everytime before selecting it. Any ideas? e.g. how to cache? other extra measures I can do?

• Creating a file upload template in Doctrine ORM

  - by balupton

  Hey all. I'm using Doctrine 1.2 as my ORM for a Zend Framework Project. I have defined the following Model for a File.

So hopefully I can do something like: File: actAs: BalFile: columns: id: primary: true type: integer(4) unsigned: true code: type: string(255) unique: true notblank: true path: type: string(255) notblank: true size: type: integer(4) type: type: enum values: [file,document,image,video,audio,web,application,archive] default: unknown notnull: true mimetype: type: string(20) notnull: true width: type: integer(2) unsigned: true height: type: integer(2) unsigned: true I'm hoping for a validator so that say if I do $File->setFile($_FILE['uploaded_file']); It will provide a validation error, except in all the doctrine documentation it has little on custom validators, especially in the contect of "virtual" fields. So in summary, my question is: How earth can I go about making a template/extension to porting this functionality? I have tried before with templates but always gave up after a day :/ If you could take the time to port the above I would greatly appreciate it.

• Logic for rate approximation

  - by Rohan

  I am looking for some logic to solve the below problem. There are n transaction amounts : T1,T2,T3.. Tn. Commission for these transactions are calculated using a rate table provided as below. if amount between 0 and A1 - rate is r1 if amount between A1 and A2 - rate is r2 if amount between A2 and A1 - rate is r3 ... ... if amount greater than An - rate is r4 So if T1 < A1 then rate table returns r1 else if r1 < T1 < r2;it returns r2. So,lets says the rate table results for T1,T2 and T3 are r1,r2 and r3 respectively. Commission C = T1 * r1 + T2 * r2 + T3 * r3 e.g; if rate table is defined(rates are in %) 0 - 2500 - 1 2501 - 5000 - 2 5001 - 10000 - 4 10000 or more- 6 If T1 = 6000,T2 = 3000, T3 = 2000, then C= 6000 * 0.04 + 3000* 0.02 + 2000 * 0.01 = 320 Now my problem is whether we can approximate the commission amount if instead of individual values of T1,T2 and T3 we are provided with T1+T2+T3 (T) In the above example if T (11000) is applied to the rate tablewe would get 6% and which would result in a commision of 600. Is there a way to approximate the commission value given T instead of individual values of T1,T2,T3?

• Bind a WPF combobox and get selecteditem to a richtextbox

  - by Peter

  Hi, I am using a dataset on the server, in this dataset I have a datatable that calls a stored procedure and returns column names from three tables. I call this stored procedure using a web service. I manage to show all the column names in my combobox but when I want to click a button and insert selected column name into a richtextbox I get System.Data.DataRowView in the textbox instead. My code: 'the combobox 'if I don't have this textblock all the values are shown vertical instead of the normal horizontal lines 'the stored procedure SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE (TABLE_NAME = 'Customer') OR (TABLE_NAME = 'Invoices') OR (TABLE_NAME = 'Orders') 'the button Private Sub btnAddColumnNames_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles btnAddColumnNames.Click ' Add column names to the richtextbox Dim tr As New TextRange(rtbText.Selection.Start, rtbText.Selection.End) tr.Text = cboColumnNames.SelectedItem.ToString() rtbText.Focus() End Sub Any suggestions on how to get the selected text in the combobox to the richtextbox?

• Java/MySQL: Working with data in classes

  - by skiwi

  What is the best way to deal with accessing/modifying tables in a database? I have read about the Data Access Object approach, but none of the resources I have found so far indicate a clear implementation of it. So assume you have a database with a table called accounts that has columns id, name, password and email. How would you properly access it within Java? I mean most people know how to do SQL statements, but that is not really the point. I hope people here can be of help. Regards.

• MYSQL - How to increment fields in one row with values from another row

  - by Walker Boh

  I have a table that we'll call 'Sales' with 4 rows: uid, date, count and amount. I want to increment the count and amount values for one row with the count/amount values from a different row in that table. Example: UID | Date | Count | Amount| 1 | 2013-06-20 | 1 | 500 | 2 | 2013-06-24 | 2 | 1000 | Ideal results would be uid 2's count/amount values being incremented by uid 1's values: UID | Date | Count | Amount| 1 | 2013-06-20 | 1 | 500 | 2 | 2013-06-24 | 3 | 1500 | Please note that my company's database is an older version of MYSQL (3.something) so subqueries are not possible. I am curious to know if this is possible outside of doing an "update sales set count = count + 1" and likewise for the amount columns. I have a lot of rows to update and incrementing the values individually is quite time consuming if you can imagine. Thanks for any help or suggestions!

• In SharePoint, how can the "Issue ID" column of an issues list be included in the detail form (DispF

  - by Jesse C. Slicer

  We've created a pretty standard issue tracking system based off of SharePoint's template with just a few extra columns. On the list view (AllItems.aspx), the first column is called "Issue ID" and has a number. Our developers and QC use that number in discussions. However, that number doesn't seem to want to show up on the detail form (DispForm.aspx) nor in the alert email. Can this field be included in at least one of these communication methods? If so, how? Thank you.

• Echoing a pseudo column value after a COUNT

  - by rob - not a robber

  Hi Gang... Please don't beat me if this is elementary. I searched and found disjointed stuff relating to pseudo columns. Nothing spot on about what I need. Anyway... I have a table with some rows. Each record has a unique ID, an ID that relates to another entity and finally a comment that relates to that last entity. So, I want to COUNT these rows to basically find what entity has the most comments. Instead of me explaining the query, I'll print it SELECT entity_id, COUNT(*) AS amount FROM comments GROUP BY entity_id ORDER BY amount DESC The query does just what I want, but I want to echo the values from that pseudo column, 'amount' Can it be done, or should I use another method like mysql_num_rows? Thank you!!!

• Problem with layout of control when dynamically creating winform and controls for the Form

  - by Ashwani Roy

  I get this response from a web service call. Something like this <Response> <Control1 type = "DropdownList" value= "USA,UK,Sweden,UAE"/> <Control2 type = "Textbox" value= "Contries"/> <Control3 type = "Button" value= "None"> </Response> Based on this I de-serialize it into List<Controls>. Now I need to be able to dynamically create a winform based on these controls. My problem is the layout. I want to be able to create them nicely separated (If possible vertically aligned) in batches of lets say 5.So If I need 15 controls I have 3 columns and 5 rows. What would be best way to achieve this? I know that I can use the inbuilt positioning properties like top, width etc., but maybe someone out there has done something similar in a better way.

• DataGridView: how to focus the whole row instead of a single cell?

  - by Tomas Sedovic

  I'd like to use the DataGridView control as a list with columns. Sort of like ListView in Details mode but I want to keep the DataGridView flexibility. ListView (with Details view and FullRowSelect enabled) highlights the whole line and shows the focus mark around the whole line: DataGridView (with SelectionMode = FullRowSelect) displays focus mark only around a single cell: So, does anyone know of some (ideally) easy way to make the DataGridView row selection look like the ListView one? I'm not looking for a changed behaviour of the control - I only want it to look the same. Ideally, without messing up with the methods that do the actual painting.

• How do you design a database to allow fast multicolumn searching?

  - by Fletcher Moore

  I am creating a real estate search from RETS data, but this is a general question. When you have a variety of columns that you would like the user to be able to filter their search result by, how do you optimize this? For example, http://www.charlestonrealestateguide.com/listings.php has 16 or so optional filters. Granted, he only has up to 11,000 entries (I have the same data), but I don't imagine the search is performed with just a giant WHERE AND AND AND ... clause. Or is this typically accomplished with one giant multicolumn index? Newegg, Amazon, and countless others also have cool & fast filtering systems for large amounts of data. How do they do it? And is there a database optimization reason for the tendency to provide ranges instead of empty inputs, or is that merely for user convenience?

• finding common prefix of array of strings

  - by bumperbox

  I have an array like this $sports = array( 'Softball - Counties', 'Softball - Eastern', 'Softball - North Harbour', 'Softball - South', 'Softball - Western' ); and i would like to find the longest common part of the string so in this instance, it would be 'Softball - '; I am thinking that I would follow the this process $i = 1; // loop to the length of the first string while ($i < strlen($sports[0]) { // grab the left most part up to i in length $match = substr($sports[0], 0, $i); // loop through all the values in array, and compare if they match foreach ($sports as $sport) { if ($match != substr($sport, 0, $i) { // didn't match, return the part that did match return substr($sport, 0, $i-1); } } // foreach // increase string length $i++; } // while // if you got to here, then all of them must be identical Questions is there a built in function or much simpler way of doing this ? for my 5 line array that is probably fine, but if i were to do several thousand line arrays, there would be a lot of overhead, so i would have to be move calculated with my starting values of $i, eg $i = halfway of string, if it fails, then $i/2 until it works, then increment $i by 1 until we succeed. so that we are doing the least number of comparisons to get a result If there a formula/algorithm out already out there for this kind of problem ? thanks alex
