• Keeping DB Table sorted using multi-field formula (Microsoft SQL)

  - by user298167

  Hello Everybody. I have a Job Table which has two interesting columns: Creation Date and Importance (high - 3, medium 2, low - 1). Job's priority calculated like this: Priority = Importance * (time passed since creation). The problem is, Every time I would like to pick 200 jobs with highest priority, I dont want to resort the table. Is there a way to keep rows sorted? I was also thinking about having three tables one for High, Medium and Low and then sort those by Creation Date. Thanks

• 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...)

• How to create reusable WPF grid layout

  - by zendar

  I have a window with tab control and number of pages - tab items. Each tab item has same grid layout - 6 rows and 4 columns. Now, each tab item contains grid with row and column definitions, so almost half of XAML is definition of grids. How can I define this grid in one place and reuse that definition in my application? Template? User control? Besides 6x4, I have only two more grid dimensions that repeat: 8x4 and 6x6.

• How to do some preformance testing in asp.net mvc?

  - by chobo2

  Hi I am using asp.net mvc 2.0 and I want to test how long it takes to do some of my code. In one senario I do this load xml file up. validate xml file and deserailze. validate all rows in the xml file with more advanced validation that cannot be done in the schema validation. then I do a bulk insert. I want to know how long steps 1 to 3 take and how long step 4 takes. I tried to do like DateTime.UtcNow in areas and subtract them but it told me it took like 3 seconds but I know that is not right as steps 1 to 4 take 2mins to do.

• Get the BindingSource position based on DataTable row

  - by Ronald

  I have a datatable that contains the rows of a database table. This table has a primary key formed by 2 columns. The components are assigned this way: datatable - bindingsource - datagridview. What I want is to search a specific row (based on the primary key) to select it on the grid. I cant use the bindingsource.Find method because you only can use one column. I have access to the datatable, so I do manually search on the datatable, but how can I get bindingsource row position based on the datatable row? Or there is another way to solve this? Im using Visual Studio 2005, VB.NET.

• CSS div positioning assistance

  - by bikey77

  I need some help with the positioning of divs that appear on each #box's hover event. The hidden divs should appear over the box that was hovered in a way that: Each #tooltip div covers the box that was hovered plus the box next to it The tooltips of boxes 1 & 2 should cover the boxes to the right #tooltips for box 3 & 4 should cover the boxes to their left (to make it more understandable, please see the attached image There will be several rows of boxes so positioning should be relative and not fixed to the page dimensions (i suppose) So far I haven't managed to get the #tooltip positionings right (I know that one should be absolute and the other relative but no matter my efforts, I haven't nailed it yet). Here's a jsfiddle to work on and this is the result i'm after:

• Changing ylim (axis limits) drops data falling outside range. How can this be prevented?

  - by Alex Holcombe

  df <- data.frame(age=c(10,10,20,20,25,25,25),veg=c(0,1,0,1,1,0,1)) g=ggplot(data=df,aes(x=age,y=veg)) g=g+stat_summary(fun.y=mean,geom="point") Points reflect mean of veg at each age, which is what I expected and want to preserve after changing axis limits with the command below. g=g+ylim(0.2,1) Changing axis limits with the above command unfortunately causes veg==0 subset to be dropped from the data, yielding "Warning message: Removed 4 rows containing missing values (stat_summary)" This is bad because now the data plot (stat_summary mean) omits the veg==0 points. How can this be prevented? I simply want to avoid showing the empty part of the plot- the ordinate from 0 to .2, but not drop the associated data from the stat_summary calculation.

• Passing a 2D array to a function in C

  - by Tyler Treat

  I have, essentially, a matrix of data (lets say ints) that I would like to store in a 2D array in which the dimensions are not known until runtime (say x columns and y rows). I want to populate the array in a function, so I assume I need to do something like this: int main(int argc, char **argv) { int y = atoi(argv[1]); int x = atoi(argv[2]); int **matrix = malloc(x * sizeof(int*)); populateMatrix(matrix, y, x); return 0; } void populateMatrix(**matrix, int y, int x) { int i, j; for (i = 0; i < y; i++) { for (j = 0; j < x; j++) { matrix[i][j] = i * j; // populated with trivial data to keep it simple } } } Obviously this doesn't work, but I'm not sure how to do what I'm describing exactly.

• extract data from an array without using loop in R

  - by Manolo

  I have a vector v with row positions: v<-c(10,3,100,50,...) with those positions I want to extract elements of a matrix, having a column fixed, for example lets suppose my column number is 2, so I am doing: data<-c() data<-c(matrix[[v]][[2]]) matrix has the data in the following format: [[34]] [1] "200_s_at" "4853" "1910" "3554" "2658" So for example, I want to extract from the row 342 the value 1910 only, column 2, and do the same with the next rows but I got an error when I want to do that, is it possible to do it directly? or should I have a loop that read one by one the positions in v and fill the data vector like: #algorithm for i<-1 to length(v) pos<-v[i] data[[i]]<-c(matriz[[pos]][[2]]) next i Thanks

• DataMapper: using auto_migrate! with many-to-many dependencies?

  - by pschuegr

  Hi, I'm trying to migrate my app from MySql to Postgresql, using Rails3-pre and the latest DataMapper. I have several models which are related through many-to-many relationships using :through = Resource, which means that DataMapper creates a join table with foreign keys for both models. I can't auto_migrate! these changes, because I keep getting this: ERROR: cannot drop table users because other objects depend on it DETAIL: constraint artist_users_owner_fk on table artist_users depends on table users constraint site_users_owner_fk on table site_users depends on table users HINT: Use DROP ... CASCADE to drop the dependent objects too. I have tried everything I can think of, and thought I had things working when I added :constraint = :skip to the field definition, but I keep getting that error back when I try and run auto_migrate. I thought that :skip meant that it would ignore the dependents, but maybe that only applies for deleting rows and not dropping tables? I should mention that I can run auto_migrate after i nuke the db once, but after that, errors. Any suggestions or advice much appreciated.

• Postgres : Post statement (or insert) asynchronous, non-blocking processing.

  - by Hassan Syed

  I'm wondering if it is possible, that after a collection of rows is inserted, to initiate an operation that is executed asynchronously, is non-blocking, and doesn't need to inform the originator of the request - of the result. I am working with large amounts of events and I can guarantee that the post-insert logic will not fail -- I just want to have a single insert thread in my event-sources, and I want this thread to keep flying without blocking, and without being responsible for any post-delivery book-keeping. I can tell you that I would potentially have a 100 of these jobs executing concurrently and each job might operate on 5 tables with anywhere between 200-1000 inserts on each of these tables. A hint in the right direction should be enough.

• php/mysql show data from chosen checkboxes

  - by Michael

  Hi. I have a table called FRUIT id type daysold 1 banana 5 2 apple 6 3 apple 4 4 peach 2 5 banana 6 What I would like is to have 3 checkboxes: Banana [ ] Apple [ ] Peach [ ] SUBMIT Then if I've only checked "Banana" and "Peach" the mysql output should only show me the rows that matches those two types. And the checkboxes should remain checked to highlight what was chosen. I can make the checkboxes but then that's about it really. I don't know how to properly get the info from the checkboxes and down to the WHERE argument in the MYSQL-code. Especially not with two types chosen. If it was just a dropdown menu with a single choice then I'd add the choice to the url and put WHERE type='$choice' - but I'm struggling with the multiple choices. I'm a bit of a novice at both php and mysql, so I'm a bit lost on this one.

• same flash file (.swf) downloaded multiple times on a page

  - by Gunjan

  I have a page that has a table with each row corresponding to an audio file. The last cell in each row embeds a simple flash audio player. The problem is that the flash file for the player is being downloaded for each row separately and as soon as rows go beyond 40-50 it crashes the browser. I tried using different players (1pixelout, flash-mp3-player) and the problem is still there, so its not a player specific issue. Is there any way to cache the player so that it is only downloaded once?

• Setting tabindex in dynamic table vertically then horizontally

  - by Wil

  I have a page that is currently generating dynamically created textboxes in a table format. The users are requesting that the tab order be changed from horizontal-vertical to vertical-horizontal. I know that you can use the tabindex attribute to control the tab ordering, but I can't for the life of me figure out the right way to get the sequential number properly for the textboxes. I guess this is more of a math question than anything else! FYI, the textboxes are made while looping two different collections. First collection looped to make the rows, for each row, second collection (which is a property of the first collection objects) is looped to create the columns. Any help would be greatly appreciated. Thanks!

• editButtonItem set but no minus buttons?

  - by QAD

  My edit button is placed in viewDidLoad: self.navigationItem.rightBarButtonItem = self.editButtonItem; It shows up correctly on the nav bar, and tapping this button indeed change it to Done. However, no minus buttons show up in my table rows. Swiping a row, then tap Delete works, though. Any ideas? EDIT 1: Here's how I'm doing: - (void)loadView { tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; tableView.delegate = self; tableView.dataSource = self; tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.view = tableView; } EDIT 2: My observation is that the edit and minus buttons display fine if my tableview is created in IB (RootViewController). The other two (or three) tableview are created by the aforemention code, so that might be the problem. Guess I'd have to dive in to isEditing, editing and whatnot.

• How do I pass a DBNull value to a parameterized SELECT statement?

  - by Dan

  I have a SQL statement in C# (.NET Framework 4 running against SQL Server 2k8) that looks like this: SELECT [Column1] FROM [Table1] WHERE [Column2] = @Column2 The above query works fine with the following ADO.NET code: DbParameter parm = Factory.CreateDbParameter(); parm.Value = "SomeValue"; parm.ParameterName = "@Column2"; //etc... This query returns zero rows, though, if I assign DBNull.Value to the DbParameter's Value member even if there are null values in Column2. If I change the query to accommodate the null test specifically: SELECT [Column1] FROM [Table1] WHERE [Column2] IS @Column2 I get an "Incorrect syntax near '@Column2'" exception at runtime. Is there no way that I can use null or DBNull as a parameter in the WHERE clause of a SELECT statement?

• MS Access CrossTab query - across 3 tables

  Hi, I have the following 3 tables: 1) Sweetness Table FruitIndex CountryIndex Sweetness 1 1 10 1 2 20 1 3 400 2 1 50 2 2 123 2 3 1 3 1 49 3 2 40 3 3 2 2) Fruit Name Table FruitIndex FruitName 1 Apple 2 Orange 3 Peaches 3) Country Name Table CountryIndex CountryName 1 UnitedStates 2 Canada 3 Mexico I'm trying to perform a CrossTab SQL query to end up with: Fruit\Country UnitedStates Canada Mexico Apple 10 20 400 Orange 50 123 1 Peaches 49 40 2 The challenging part is to label the rows/columns with the relevant names from the Name tables. I can use MS Access to design 2 queries, create the joins the fruit/country names table with the Sweetness table perform crosstab query However I'm having trouble doing this in a single query. I've attempted nesting the 1st query's SQL into the 2nd, but it doesn't seem to work. Unfortunately, my solution needs to be be wholly SQL, as it is an embedded SQL query (cannot rely on query designer in MS Access, etc.). Any help greatly appreciated. Prembo.

• Killing the mysqld process

  - by Josh K

  I have a table with ~800k rows. I ran an update users set hash = SHA1(CONCAT({about eight fields})) where 1; Now I have a hung Sequel Pro process and I'm not sure about the mysqld process. This is two questions: What harm can possibly come from killing these programs? I'm working on a separate database, so no damage should come to other databases on the system, right? Assume you had to update a table like this. What would be a quicker / more reliable method of updating without writing a separate script. I just checked with phpMyAdmin and it appears as though the query is complete. I still have Sequel Pro using 100% of both my cores though...

• Filter the datagridview column based on the current row of another column in C#

  - by user286546

  I have a datagridview that is populating columns from different table. I want to filter the column based on another column of the current row. I tried to use the cell enter event of the datagridview and then filtered the column by filtering the binding source on the column of the current row. private void lINKDataGridView_CellEnter(object sender, DataGridViewCellEventArgs e) { this.pROBLEMBindingSource.Filter = "item_id = " + this.lINKDataGridView.Rows[e.RowIndex].Cells[dataGridViewTextBoxColumn4.Index].Value + ""; } This is how I am filtering the "problem " binding source on the cell enter event of the datagridview . It is working fine but I am getting an error- being: System.ArgumentException: DataGridViewComboBoxCell value is not valid. Any suggestion

• Is adding a bit mask to all tables in a database useful?

  - by Tom

  A colleague is adding a bit mask to all our database tables. In theory this is so we can track certain properties of each row across the entire system. For example... Is the row shipped with the system or added by the client once they've started using the system Has the row been deleted from the table (soft deletes) Is the row a default value within a set of rows Is this a good idea? Are there other uses where this approach would be beneficial? My preference is these properties are obviously important, and having a dedicated column for each property is justified to make what is happening clearer to fellow developers.
