• Workaround for Outlook 2007 for wrapping text around image with margin?

  - by DavidW

  As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

• Only the last run in a for loop in Javascript works

  - by Mengfei Murphy

  Here is a for loop written by Javascript. It is trying to apply queries for websql. for (var i = 0; i < 10; i++){ db.transaction(function (tx){ tx.executeSql('INSERT INTO ProjSetsT (ProjID) VALUES (?);', [i]); }); } The attempt is obvious, I tried to add values "0, 1, 2, ... 9" into column ProjID in table ProjSetsT. It does not work. I only got the last element, i.e. "9" inserted, but not the first eight numbers. Is there any syntax mistakes?

• Rails Habtm with a field

  - by moshimoshi

  Hello, Is that possible to have a field in a has and belongs to many table? Just like favorite: create_table :messages_users, :id => false, :force => true do |t| t.integer :message_id, :null => false t.integer :user_id, :null => false t.boolean :favorite, :null => false t.timestamps end I saw timestamps works well, thanks to ActiveRecord. But when I try to add favorite into the table and then I try: Message.first.users << User.first Then I get this error message: ActiveRecord::StatementInvalid: SQLite3::SQLException: messages_users.favorite may not be NULL: INSERT INTO "messages_users" ("created_at", "message_id", "updated_at", "user_id") VALUES ('''2010-05-27 06:07 :50.721512''', 1, '''2010-05-27 06:07:50.721512''', 1) I would like to use a habtm, I don't like has_many foo though bar association :) Is that possible? Thanks a lot.

• Anchoring the Action URL of a Form

  - by John

  Hello, I am using a function that leads users to a file called "comments2.php": <form action="http://www...com/.../comments/comments2.php" method="post"> On comments2.php, data passed over from the form is inserted into MySQL: $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); Then, later in comments2.php, I am using a query that loops through entries meeting certain criteria. The loop contains a row with the following information: echo '<td rowspan="3" class="commentname1" id="comment-' . $row["commentid"] . '">'.stripslashes($row["comment"]).'</td>'; For the function above, I would like the URL to be anchored by the highest value of "commentid" for id="comment-' . $row["commentid"] . '" How can this be done? Thanks in advance, John

• Determine if on product page programmatically in Magento

  - by dfondente

  I want to insert tracking codes on all of the pages of a Magento site, and need to use a different syntax if the page is a CMS page, a category browsing page, or a product view page. I have a custom module set up with a block that inserts a generic tracking code on each page for now. From within the block, how can I distinguish between CMS pages, category pages, and product pages? I started with: Mage::app()->getRequest(); I can see that Mage::app()->getRequest()->getParam('id'); returns the product or category ID on product and category pages, but doesn't distinguish between those page types. Mage::app()->getRequest()->getRouteName(); return "cms" for CMS pages, but returns "catalog" for both category browsing and product view pages, so I can't use that to tell category and product pages apart. Is there some indicator in the request I can use safely? Or is there a better way to accomplish my goal of different tracking codes for different page types?

• A follow up on type coercion in C++, as it may be construed by type conversion

  - by David

  This is a follow up to my previous question. Consider that I write a function with the following prototype: int a_function(Foo val); Where foo is believed to be a type defined unsigned int. This is unfortunately not verifiable for lack of documentation. So, someone comes along and uses a_function, but calls it with an unsigned int as an argument. Here the story takes a turn. Foo turns out to actually be a class, which can take an unsigned int as a single argument of unsigned int in an explicit constructor. Is it a standard and reliable behavior for the compiler to render the function call by doing a type conversion on the argument. I.e. is the compiler supposed to recognize the mismatch and insert the constructor? Or should I get a compile time error reporting the type mismatch.

• How do I seperate Punctuations in a sentence with a space between each phrase and punctuation in C++

  - by Yadollah

  I want to write a program in c++ that get a sentence and insert a space between each word and punctuation in it! in perl this is done with this expression: sed -e "s/,\([^0-9]\)/ , \1/g" -e "s/\.\([^0-9]\)/ . \1/g" -e 's/\.[ ]*$/ ./g' -e "s/\'/ \' /g" -e 's/?/ ?/g' -e 's/\`\`/ `` /g' -e "s/\' \'/''/g" -e 's/(/ ( /g' -e 's/)/ ) /g' -e 's/ \. \([^$]\)/. \1/g' -e "s/\' s/\'s/g" -e "s/\"\([^\"]*\)\"/\" \1 \"/g" $1 | sed -e "s/\"\([^\"]*\)\"/\`\`\1''/g" But I don't khow how i should do this in c++! for example: should convert a "The question now: Can he act more like hard-charging Teddy Roosevelt." must be converted to "The question now : Can he act more like hard-charging Teddy Roosevelt ." So a punctuation such as '-' or for example a '.' in "No." should not spacing in a sentence, but other punctuation that don't rely on a word or a phrase should be spaced.

• SQL Server Query Editors - any that warn of number of rows to be changed?

  - by ciaranarcher

  We're using SQL Server 2000 Query Analyser, and one issue we have is that very occasionally, when a user is updating our live database, they insert the incorrect/no(!) where clause. I know, not good, but it happens. Are there any editors that will warn of the number of rows that might be changed (if that is even possible) or even a way to configure an editor, if it is connected to a certain database, to prompt for confirmation before the query is run? We have a way to recover our data in the cases where we run an incorrect query, but it takes time, and I'm just seeing if there are any ways to catch the error, or at least give the user a second chance. Thanks in advance.

• Low cost way to host a large table yet keep the performance scalable?

  - by Leo Liang

  I have a growing table storing time series data, 500M entries now, and 200K new records every day. The total size is around 15GB for now. My clients are querying the table via a PHP script mostly, and the size of the result set is around 10K records (not very large). select * from T where timestamp > X and timestamp < Y and additionFilters And I want this operation cheap. Currently my table is hosting in Postgres 7, on a single 16G memory Box, and I would love to see some good suggestion for me to host this in low cost and also allow me to scale up for performance if needed. The table serves: 1. Query: 90% 2. Insert: 9.9% 2. Update: 0.1% <-- very rare.

• error in mysql syntax in vb.net

  I get this error, while I'm testing the code below: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '[student](ID, LASTNAME, FIRSTNAME, SCHOOL) VALUES ('333', 'aaa', 'aaa', 'aaa')' at line 1 I just recycled the code that I used in manipulating ms sql database.

• how to have separate keys per record in mongo_mapper + Rails

  - by Vitaly Kushner

  When I'm adding a record in mongodb I can specify whatever keys I want and it will store it in the db. The problem is that it will remember those keys for the next time I insert another record. so for example if I do the following: Product.create :foo => 123 and then Product.create :bar => 456 I get :foo => nil field in the 2nd record. This is definitely not a limitation of mongodb itself, since if I restart the rails console and create yet another record with different set of columns, it will not add the columns from the 1st 2 records. So it seems like mongomapper remembers all the keys used and inserts them all into all records, even if values are not provided. The question is obviously: how do I disable this crazy attributes explosion? Basically I want only the 'permanent' keys that I specify in the model to be in every record, but all the 'extra' attributes to be specified per record and not to mess the consequent records.

• Random Computer Crashes

  - by Josh W.

  Ok, here's a wierd one for you all. Occasionally my PC here at work will crash in a very peculiar way. My dual monitors will suddenly go blank as if there is no longer a video signal, the USB mouse light will go dark and mouse stays unresponsive, the keyboard lights will not change status when the appropriate keys are pressed (Num/Caps/Scoll Lock). The CD Tray WILL open and close. But the computer will not respond to a ping request. For all intents & purposes it's as if the computer is off, except it wasn't intentional by me. The power light and internal fans are still on and I've now lost any unsaved work. Now here's where it gets wierd. This PC is part of a batch of PC's we got from a local vendor who does our initial system builds. Mine, and 6 other co-workers PCs all have the same issue. Originally we thought it was a bad combination of hardware, but through trial and error the only thing we haven't eliminated are the OS, Mobo & CPU. The problem was so bad for some of them that they ended up going back to their 5 year old dinosaurs in order to get some work done, for me the problem isn't as bad, maybe once every other day or so, but still enough to bite me in the ass if I've forgotten my ritualistic pressing of CTRL-S every 1-5 minutes. In this case we've tried two different video cards, two different power supplies, two different memory configurations, running on a UPS/not on UPS, updating/rolling back video drivers, three different bios revisions. The only things we haven't swapped are the mobo & cpu, mainly because a new mobo means a new Hardware Abstraction Layer, ie re-install of windows and there's alot of other software on this PC that takes forever to reload by hand. There was a base image that our systems team created with all the drivers installed and the basic setup of software our company uses, but they then must customize the setup for us programmers so it takes a while to get a new configuration up and going. I'm a programmer by day and am usually pretty good at diagnosing computer problems whether through trial and error or not. We've pretty much exhausted all the ideas we can think of here, short of a new mobo/cpu. Was hoping someone out there might have anything else we can try.. Relevant Parts: OS: XP Pro 32-bit Motherboard: Intel DG41RQ CPU: Intel Core-2 Quad Q9400 @ 2.66GHz Current BIOS Version/Date Intel Corp.

• Crystal Reports and WMF image

  - by Eve

  I have a problem with inserting a vector graphics (WMF) into report (Crystal Reports v10.5 from Visual Studio 2008). The image is static, inserted by choosing "Insert Picture" during report design in VS. The problem is that it displays differently (size and aspect ratio) on machines with different operating systems and screen resolutions. Converting to bitmap isn't possible beacause loss of the quality of print isn't acceptable. I thought about dynamic loading of the image, but in this version of CR. I don't see a possibility to set dynamic graphic location in picture properties. Is there any way to solve this problem?

• Carrierwave upload to a tmp dir before saving to database

  - by user827570

  I'm trying to build a visual editor where users can click an image they are presented with an image upload form once the upload is done I use ajax to return the image and insert it back into the page. But the above method inserts the image straight into the database but I want users to be able to visualize the image before the image is inserted into the database. So I was wondering if the image using carrierwave could be uploaded to a temp location, sent back to the user and then when the user saves the page the image is moved into the permanent location. Here's what I have so far. def edit_image @page = Page.find(1) @page.update_attributes(params[:page]) @page.save return :text => @page.file end But this is what I want to achieve def temp_image #uploads received image to a temp location #returns image to the user end And once the user clicks save def save #moves the file in the temp folder to the permanent location end Cheers

• MySQL triggers cannot update rows in same table the trigger is assigned to. Suggested workaround?

  - by Cory House

  MySQL doesn't currently support updating rows in the same table the trigger is assigned to since the call could become recursive. Does anyone have suggestions on a good workaround/alternative? Right now my plan is to call a stored procedure that performs the logic I really wanted in a trigger, but I'd love to hear how others have gotten around this limitation. Edit: A little more background as requested. I have a table that stores product attribute assignments. When a new parent product record is inserted, I'd like the trigger to perform a corresponding insert in the same table for each child record. This denormalization is necessary for performance. MySQL doesn't support this and throws: Can't update table 'mytable' in stored function/trigger because it is already used by statement which invoked this stored function/trigger. A long discussion on the issue on the MySQL forums basically lead to: Use a stored proc, which is what I went with for now. Thanks in advance!

• Search a string to find which records in table are inside said string

  - by Improfane

  Hello, Say I have a string. Then I have a number of unique tokens or keywords, potentially a large number in a database. I want to search and find out which of these database strings are inside the string I provide (and get the IDs of them). Is there a way of using a query to search the provided string or must it be taken to application space? Am I right in thinking that this is not a 'full text search'? Would the best method be to insert it into the database to make it a full text search?

• MongoDB query to return only embedded document

  assume that i have a BlogPost model with zero-to-many embedded Comment documents. can i query for and have MongoDB return only Comment objects matching my query spec? eg, db.blog_posts.find({"comment.submitter": "some_name"}) returns only a list of comments. edit: an example: import pymongo connection = pymongo.Connection() db = connection['dvds'] db['dvds'].insert({'title': "The Hitchhikers Guide to the Galaxy", 'episodes': [{'title': "Episode 1", 'desc': "..."}, {'title': "Episode 2", 'desc': "..."}, {'title': "Episode 3", 'desc': "..."}, {'title': "Episode 4", 'desc': "..."}, {'title': "Episode 5", 'desc': "..."}, {'title': "Episode 6", 'desc': "..."}]}) episode = db['dvds'].find_one({'episodes.title': "Episode 1"}, fields=['episodes']) in this example, episode is: {u'_id': ObjectId('...'), u'episodes': [{u'desc': u'...', u'title': u'Episode 1'}, {u'desc': u'...', u'title': u'Episode 2'}, {u'desc': u'...', u'title': u'Episode 3'}, {u'desc': u'...', u'title': u'Episode 4'}, {u'desc': u'...', u'title': u'Episode 5'}, {u'desc': u'...', u'title': u'Episode 6'}]} but i just want: {u'desc': u'...', u'title': u'Episode 1'}

• node.js with SQL Server Native Client 11 scope_identity not being returned
