  • Regexp for selecting spaces between digits and decimal char

    - by Tirithen
    I want to remove spaces from strings where the space is preceeded by a digit or a "." and acceded by a digit or ".". I have strings like: "50 .10", "50 . 10", "50. 10" and I want them all to become "50.10" but with an unknown number of digits on either side. I'm trying with lookahead/lookbehind assertions like this: $row = str_replace("/(?<=[0-9]+$)\s*[.]\s*(?=[0-9]+$)/", "", $row); But it does not work...

  • Android ScrollView issue

    - by Salman
    Guys, We are trying to make a board with sticky notes. We have used ScrollView in which we have LinearLayout. We have four columns. If there are more than 3 notes in one column, scrollview comes up. Issue is, if I try to move Row 5 column 1 note to Row 1 Column 2, scroll views hides all the notes. If we scroll to top of the board, notes become visible again. Any idea what's the issue ? Thanks Salman

  • Why do mainframe greybeards refer to DB2/zOS as "he"? [closed]

    - by Alex Nauda
    If you ask a DB2/zOS engine DBA a question about DB2's behavior, the DBA will refer to the DB2 engine as "he" much the way a sailor uses "she" to refer to his ship. For example: "Once you fill the freespace, DB2 still wants to keep those rows in cluster order in the tablespace. That's why he'll split that page in half, and you end up with lots of half-empty pages. That is, unless the cluster key of the row you've just inserted is the highest in the table, in which case he makes a new empty page, and he puts just your new row into that page. So I wouldn't have to do this REORG if you would just sort your input like I suggested." Does anyone know where this tradition comes from?

  • Complex Join - involving date ranges and sum...

    - by calumbrodie
    I have two tables that I need to join... I want to join table1 and table2 on 'id' - however in table two id is not unique. I only want one value returned for table two, and this value represents the sum of a column called 'total_sold' - within a specified date range (say one month).. SELECT ta.id, tb.total_sold as total_sold_this_week FROM table_a as ta LEFT JOIN table_b as tb ON ta.id=tb.id AND tb.date_sold BETWEEN ADDDATE(NOW(),INTERVAL -3 WEEK) AND NOW() this works but does not SUM the rows - only returning one row for each id... how do I get the sum from table b instead of only one row??? Please criticise if format of question could use more work - I can rewrite and provide sample data if required - this is a trivialised version of a much larger problem. -Thanks

  • Bind Data to Multiple Labels From Multiple DataSources

    - by Steven
    I have two AccessDataSources each returning one row. I want to use the data in each row to populate content on my page, so I figured I would use a Repeater or FormView. However, I would not necessarily want the labels bound to a particular DataSource placed together. For example, I might want labels from the following columns in order (DataSourceName.ColumnName): TestSetup.TestType, TestSummary.FormattedValue, TestSetup.DeviceChannel, TestSummary.CompletedOn. How do I handle this? Do I just have a separate Repeater/FormView for each value? Can I have both Repeater's/FormView's in 'scope' at the same time? Note: No language preference (C#/VB).

  • Mac OS X: How to change word separator characters?

    - by avetis.kazarian
    Depending on your system, the word separator characters change the way you can select/delete a word (e.g. by double clicking on it or using a key combination with your keyboard). The fact is that I hate the default behavior of OSX. For example: Take the following line of code: obj.attr1.innerAttr. If my cursor is at the end of the line and I press alt + backspace, it will delete everything and not just innerAttr. I only found some apps (like iTerm) which let you change the word separator characters. Is there a way to change it for the whole system?

  • ListView OnItemClickListener Not Responding?

    - by GuyNoir
    I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.

  • Android: How to find the position clicked from the context menu

    - by Josemalive
    Hi, I have a list view filled with data. I set up a context menu for the listview using the following code: list.setOnCreateContextMenuListener ( new View.OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View view, ContextMenu.ContextMenuInfo menuInfo) { AdapterContextMenuInfo mi =(AdapterContextMenuInfo) menuInfo; menu.add(0, 0, 0, "Delete item"); } } ); I have the following method override to control de contextmenu menuitem selected: @Override public boolean onContextItemSelected(MenuItem item) { switch(item.getItemId()) { case 0: ShowAlert("hello from delete item"); break; default: return super.onContextItemSelected(item); } return true; } In this overrided method, how could i find the item of the list view that was clicked? Thanks in advance. Best Regards. Jose

  • MySQL - are FK's useful / viable in a web app?

    - by yoda
    Hi all, I've encountered this discussion related to FK's and web applications. Basically some people say that FK's in web applications doesn't represent a real improvement and can even make the application slower in some cases. What do you guys think, what's your experience? -- A quote from Heikki Tuuri, creator of InnoDB engine, founder and CEO of Innobase: InnoDB checks foreign keys as soon as a row is updated, no batching is performed or checks delayed till transaction commit Foreign keys are often serious performance overhead, but help maintain data consistency Foreign Keys increase amount of row level locking done and can make it spread to a lot of tables besides the ones directly updated

  • Force 'Replace Into' to use a certain index

    - by Bobby
    I have a MySQL (5.0) table with 3 rows which are considered a combined Unique Index: CREATE TABLE `test`.`table_a` ( `Id` int(11) NOT NULL AUTO_INCREMENT, `field1` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', `field2` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', `field3` varchar(5) COLLATE latin1_swedish_ci NOT NULL DEFAULT '', PRIMARY KEY (`Id`), INDEX `IdxUnqiue` (`field1`(5),`field2`(5),`field3`(5)) ) ENGINE=MyISAM; This table should be filled with a REPLACE INTO query: REPLACE INTO table_a ( Field1, Field2, Field3 ) VALUES ( "Test1", "Test2", "Test3" ) The behavior I'd like to see is that this query always overrides the previous inserted row, because IdxUnique is...ahm, triggered. But unfortunately, there's still the primary index which seems to kick in and always inserts a new row. What I get: Query was executed 3 times: +---Id---+---Field1---+---Field2---+---Field3---+ | 1 | Test1 | Test2 | Test2 | | 2 | Test1 | Test2 | Test2 | | 3 | Test1 | Test2 | Test2 | +--------+------------+------------+------------+ What I want: Query was executed 3 times: +---Id---+---Field1---+---Field2---+---Field3---+ | 3 | Test1 | Test2 | Test2 | +--------+------------+------------+------------+ So, can I tell REPLACE INTO to use just a certain Index or to consider one 'more inportant' then another?

  • getting mysql_insert_id() while using ON DUPLICATE KEY UPDATE with PHP

    - by julio
    Hi-- I've found a few answers for this using mySQL alone, but I was hoping someone could show me a way to get the ID of the last inserted or updated row of a mysql DB when using PHP to handle the inserts/updates. Currently I have something like this, where column3 is a unique key, and there's also an id column that's an autoincremented primary key: $query ="INSERT INTO TABLE (column1, column2, column3) VALUES (value1, value2, value3) ON DUPLICATE KEY UPDATE SET column1=value1, column2=value2, column3=value3"; mysql_query($query); $my_id = mysql_insert_id(); $my_id is correct on INSERT, but incorrect when it's updating a row (ON DUPLICATE KEY UPDATE). I have seen several posts with people advising that you use something like INSERT INTO table (a) VALUES (0) ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id) to get a valid ID value when the ON DUPLICATE KEY is invoked-- but will this return that valid ID to the PHP "mysql_insert_id()" function? Thanks for any advice.

  • Problem in displaying custom UITableViewCell

    - by Vin
    Hi All, I have a tableview displaying data using a custom UITableViewCell(say cell1). On touch of a row, I change the custom cell to another custom UITableViewCell(say cell2). Also I increase the size of row of the selected cell to accomodate, more items of cell2. My problem is that the approach works fine when the number of rows in table view is less. When the number of rows increses, the rows expand on touching, but the data displayed is same as that of cell1. Cell2 doesn't seem to be loaded at all. Looking forward for a reply soon....Thanks in advance.

  • What ways can I put images in a grid-like format?

    - by Peter
    I have about 12-15 images that I want to align together in a grid, with text under each image. I thought about using a table, but I hear that tables aren't the best way to go these days. I tried a few other things, but nothing seemed to work the way I wanted it to. An example of what I want it to look like would be something like this: [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 1 (--Description-) (-Description-) (-Description-) (-Description-) [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 2 (--Description-) (-Description-) (-Description-) (-Description-) and so on... What are some other methods, besides tables, that I should look into using? Any suggestions or references would be helpful.

  • Can I free memory passed to SysAllocString?

    - by RichAmberale
    When allocating a new BSTR with SysAllocString via a wchar_t* on the heap, should I then free the original wchar_t* on the heap? So is this the right way? wchar_t *hs = new wchar_t[20]; // load some wchar's into hs... BSTR bs = SysAllocString(hs); delete[] hs; Am I supposed to call delete here to free up the memory? Or was that memory just adoped by the BSTR?

  • updating batches of data

    - by gaponte69
    I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

  • In VisualStudio 2008, emacs mode - how can you enable "overwrite"?

    - by Abby Fichtner
    Using VisualStudio 2008, have emacs keyboard mapping scheme enabled. If I select text and try to paste over it, it INSERTS the new text, rather than replacing it. Also, if I select text and hit DELETE it deletes the first character AFTER the selected text (just as if I didn't have any text selected). Does anyone know how to fix this so that I get the standard windows behavior. That is: If I select text and try to paste over it, it replaces the selected text with what I pasted in. If I select text and hit the DELETE key, it actually deletes the text I have selected Thanks! Abby

  • Index on column with only 2 distinct values

    - by Will
    I am wondering about the performance of this index: I have an "Invalid" varchar(1) column that has 2 values: NULL or 'Y' I have an index on (invalid), as well as (invalid, last_validated) Last_validated is a datetime (this is used for a unrelated SELECT query) I am flagging a small amount of items (1-5%) of rows in the table with this as 'to be deleted'. This is so when i DELETE FROM items WHERE invalid='Y' it does not perform a full table scan for the invalid items. A problem seems to be, the actual DELETE is quite slow now, possibly because all the indexes are being removed as they are deleted. Would a bitmap index provide better performance for this? or perhaps no index at all?

  • Turning A Stacked List into workable data

    - by BoSox
    In Excel I have a list of names that in the cell appear stacked, and I want each name in its own column. I was thinking Python may be a good way to do this? Example: Joe Smith John Hawk Mike Green Lauren Smith One cell will look exactly like that, with each name on its line within the cell but all of the names contained in the cell. I have 50 cells each with 1-20 stacked names and I want to put each name in its own cell on a given row. So, in my example all of those names would occupy the same row but each would have their own column. Any ideas?
