• How to build a C++ Dll wrapper that catches all exceptions?

  - by bart de vries

  Like the title says, we’re looking for a way to catch all exceptions from a piece of C++ code, and wrap this in a dll. This way we can shield of the application that uses this dll, from any errors occurring in this dll. However, this does not seem possible with C++ under Windows. Example: void function() { try { std::list<int>::iterator fd_it; fd_it++; } catch(...) {} } The exception that occurs is not caught by the standard C++ try/catch block, nor by any SEH translator function set by _set_se_translator(). Instead, the DLL crashes, and the program that uses the DLL is aborted. We compiled with Visual C++ 2005, with the option /SHa. Does anyone know if it’s possible in C++/Win32 to catch these kind of problems and make a rocksolid DLL wrapper?

• Visual Studio 2010 Formatting

  - by Rosarch

  I have plenty of experience with Eclipse, and now I'm trying out Visual Studio 2010. I find its formatting somewhat counter-intuitive. Here are some things I'm trying to figure out: Is there a way to select all text and format/indent it properly, like SHIFT+A SHIFT+I in Eclipse? Why is it that when I type a line like if (n == 0) {, as soon as I type the opening brace, the text cursor is moved to the beginning of the line? Is this some productivity speedup I'm failing to see? When I hit ENTER after the aforementioned line, I'd like the closing brace to be put in place automatically for me. How can I do this? I've looked for hotkey documentation, and it's helped a bit, but this still feels clunky to me.

• Vim: Pasting from clipboard and automatically toggling :set paste

  - by Jonatan Littke

  Hey. When I paste things from the clipboard, they're normally (always) multilined, and in those cases (and those cases only), I'd like :set paste to be triggered, since otherwise the tabbing will increase with each line (you've all seen it!). Though the problem with :set paste is that it doesn't behave well with set smartindent, causing the cursor to jump to the beginning of a new line instead of at the correct indent. So I'd like to enable it for this instance only. I'm using Mac, sshing to a Debian machine with vim, and thus pasting in Insert mode using cmd-v. Cheers.

• Add XSLT 2 schema to Visual Studio 2010 for intellisense

  - by David Merrilees

  I'd like to add the XSLT 2 schema to Visual Studio 2010 to provide intellisense. I've added the schema to C:\Program Files\Microsoft Visual Studio 10.0\Xml\Schemas (removing the XSLT 1 schema), but to no avail. The schema seems to have been parsed by Visual Studio, as I can hover my cursor over the namespace declaration in the stylesheet (xmlns:xsl="http://www.w3.org/1999/XSL/Transform") and see the comments from the new schema, however, intellisense still refers to the XSLT 1 implementation. For example the element has a warning that 'xsl:function is not yet available'. Do I need to register the schema in some way? Any suggestions welcome.

• Port C's fread(&struct,....) to Python

  - by user287669

  Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have: typedef struct { uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH]; uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH]; uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH]; } __attribute__((__packed__)) frame_t; frame_t frame; while (! feof(stdin)) { fread(&frame, 1, sizeof(frame), stdin); // DO SOME STUFF } Later I need to access the data like so: frame.Y[x][y] So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated. Thanks

• Strange IE7 behaviors(or not)

  - by c0mrade

  I see no reason why this shouldn't work in all browsers, here is my css for anchor tag : .myButton{ background:none repeat scroll 0 0 #FFFFFF; border:1px solid #D8DFEA !important; color:#3B5998; cursor:pointer; font-size:20px; padding:10px; } Here is how it looks in IE7 : And here is how it looks in other browsers : HTML is nothing unusual as well : <a href="#" class="myButton">Beta</a> All of this is inside table, this anchor html is wrapped around with : <tr> <td><a>...</a></td> <tr> I don't think this has to do it with anything but I mentioned it just in case, so the button is missing border top, any indications what might cause this?

• Artificial Intelligence in online game using Google App Engine

  - by Hortinstein

  I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)

• Nested ng repeat not working

  - by Rodrigo Fonseca

  Ok, i've two ng-repeat working here, the first(board in boards) is working good, no problem, but the second(task in tasks), when i try to get "{{task.title}}" i don't get anything but i can display all the style from it... here is my model: $scope.tasks = [{boardIndex: 0, title: "test"}, {boardIndex: 1, title: "test2"}]; Here is my code(it's in jade, ok?) section(data-ng-repeat="board in boards", ng-cloak) .board_header div(data-ng-controller="AddTaskBtnController") i.add_task_btn.fa.fa-plus-square-o.fa-2x(ng-click='setSelected(board.id)', ng-class="{icon_add_hover: isSelected(board.id)}") h2(data-ng-bind="board.title") .content_board .task(data-ng-repeat="task in tasks", data-ng-if="task.boardIndex == board.id", data-ng-controller='TaskController', data-ng-hide='modeTask', data-ng-init='setTaskId()') .user_icon_task i.fa.fa-user.fa-3x.icon-user-not-selected .quest_task .puzzle_task(data-ng-hide='modeTask') i.fa.fa-check-circle-o.fa-lg h2 {{task.title}} ul.icons_details_task_wrapper li i.fa.fa-check-circle-o span.icon_counter li.pull_left i.fa.fa-puzzle-piece span.icon_counter ul.task_details_wrapper li.task_priority(data-ng-show='goal.selectedDrawAttention', data-ng-click='toggleSelected()', data-ng-class='{draw_attention_selected: goal.selectedDrawAttention }', style='cursor: inherit;') i.fa.fa-eye li.task_priority i.fa .task_time_ago span(am-time-ago='message.time')

• Wordpress: Check if there are previous posts before displaying link

  - by Chris Armstrong

  I'm using the following code to display a 'previous posts' link on my Wordpress blog. <nav> <ul> <li><?php previous_posts_link('Newer Entries &raquo;') ?></li> </ul </nav> Problem is, when there ARN'T any previous posts, while the link doesn't display, I still get <nav> <ul> <li><</li> </ul </nav> Printed out. Is there an if() statement I could wrap around it all so it checks if there are any previous posts, and only prints it out if there are?

• Synchronisation construct inside pragma for

  - by Sayan Ghosh

  Hi, I have a program block like: for (iIndex1=0; iIndex1 < iSize; iIndex1++) { for (iIndex2=iIndex1+1; iIndex2 < iSize; iIndex2++) { iCount++; fDist =(*this)[iIndex1].distance( (*this)[iIndex2] ); m_oPDF.addPairDistance( fDist ); if ((bShowProgress) && (iCount % 1000000 == 0)) xyz_exception::ui()->progress( iCount, (size()-1)*((size()-1))/2 ); } } } } I have tried parallelising the inner and outer loop and by putting iCount in a critical region. What would be the best approach to parallelise this? If I wrap iCount with omp single or omp atomic then the code gives an error and I figured out that would be invalid inside omp for. I guess I am adding many extraneous stuffs to paralellise this. Need some advice... Thanks, Sayan

• STOP ERASING MY QUESTIONS! - VIEWING FIRST_ROWS BEFORE QUERY COMPLETES (RE-VISITED)

  - by Frank Developer

  OK, so say I have a table with 500K rows, then I ad-hoc query with unsupported indexing which requires a full table scan. I would like to immediately view the first rows returned while the full table scan continues. Then I want to scroll thru the next results. In the meantime, I would like to display the progress of the table scan, example: "SEARCHING.. FOUND 23 OF 500,000 ROWS SO FAR". If I scroll too far ahead, I want to display a message like: "REACHED LAST ROW IN LOOK-AHEAD BUFFER.. QUERY HAS NOT COMPLETED".. Can this be done? Maybe like: spawn/exec, declare scroll cursor, open, fetch, etc.?

• Perform Grouping of Resultset in Code

  - by NinjaBomb

  Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

• Can you automatically create a mysqldump file that doesn't enforce foreign key constraints?

  - by Tai Squared

  When I run a mysqldump command on my database and then try to import it, it fails as it attempts to create the tables alphabetically, even though they may have a foreign key that references a table later in the file. There doesn't appear to be anything in the documentation and I've found answers like this that say to update the file after it's created to include: set FOREIGN_KEY_CHECKS = 0; ...original mysqldump file contents... set FOREIGN_KEY_CHECKS = 1; Is there no way to automatically set those lines or export the tables in the necessary order (without having to manually specify all table names as that can be tedious and error prone)? I could wrap those lines in a script, but was wondering if there is an easy way to ensure I can dump a file and then import it without manually updating it.

• ViewController vs. View

  - by James

  Trying to wrap my head around the apple design scheme. I have a UIViewController and the corresponding XIB file that has my main screen in my application. I want to have a button on this XIB that displays another "form" (this is my disconnect) in the foreground where the user selects from a myriad of choices, then it hides that "form" and goes back to the first one. I'm completely lost here. Initially I thought I'd just add another view and set the self.view of my controller to the new view, add another IBAction and call it a day, but I can't seem to make that work. For sake of argument, say I want to "gray out" the current form, have a modal type window that takes up roughly 60% of the screen and requires you select an option, then it hides itself and we go back to normal. What is the standard approach here? Thanks

• Build a JavaScript wrapper for a rails-generated XML API?

  - by Thor Thurn

  I am working with a large website written in Ruby on Rails. Thanks to the support for REST in Rails 2, the site's business logic is all accessible via a consistent XML API. Now I want to be able to easily write one or more JavaScript frontends to the site that interact with the generated Rails XML API. Ideally, an automated wrapper for the API could be created in JavaScript, since this would minimize the effort required in writing XML processing code for the more than 500 API functions. How, then, can I automatically generate a wrapper around a given XML API in JavaScript so that it's more pleasant to work with? I've worked with solutions of this nature for Java that generate classes and methods to wrap an API, so my current thinking is that I want something of that nature for JavaScript. I'd be open to an alternative take on the problem, though.

• JavaScript function pass-through?

  - by Lance May

  I'm not sure if this is doable, but I would like to be able to set a jQuery UI event as a function (directly), as opposed to continuing to wrap in additional function(event, ui) { ... } wrappers. Hopefully you can see what I'm going for from the example below. Here is what I would like: $("#auto").autocomplete({ source: "somepage.php", select: dropdownSelect, minLength: 0 }); Now I would think that the above would work, since I'm simply trying to say "continue firing this event, just over to that function". Unfortunately, that will not work, and I'm ending up with this: (and for some reason, a disconnect from all data) $("#auto").autocomplete({ source: "somepage.php", select: function(event, ui) { dropdownSelect(event, ui) }, minLength: 0 }); Thanks much in advance.

• Trying to parse xml, but xmldocument.loadxml() is trying to download?

  - by maxp

  I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

• SQL get data out of BEGIN; ...; END; block in python

  - by Claudiu

  I want to run many select queries at once by putting them between BEGIN; END;. I tried the following: cur = connection.cursor() cur.execute(""" BEGIN; SELECT ...; END;""") res = cur.fetchall() However, I get the error: psycopg2.ProgrammingError: no results to fetch How can I actually get data this way? Likewise, if I just have many selects in a row, I only get data back from the latest one. Is there a way to get data out of all of them?

• dojo connect mouseover and mouseout

  - by peirix

  When setting up dojo connections to onmouseover and onmouseout, and then adding content on mouseover, dojo fires the onmouseout event at once, since there is new content. Example: dojo.query(".star").parent().connect("onmouseover", function() { dojo.query("span", this).addContent("<img src='star-hover.jpg'>"); }).connect("onmouseout", function() { dojo.destroy(dojo.query("img", this)[0]); }); The parent() is a <td>, and the .star is a span. I want to add the hover image whenever the user hovers the table cell. It works as long as the cursor doesn't hover the image, because that will result in some serious blinking. Is this deliberate? And is there a way around it?

• How do I set sys.excepthook to invoke pdb globally in python?

  - by saffsd

  From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.

• click-event doesn't fire if blur changes layout

  - by rag

  I have a form with blur-events bound to the required fields. Then there is a "Cancel" Button which simply calls an URL (button is an image with click-event). When leaving one of the required fields a warning is written to the page saying that field xy is required. - this causes a layout shift, meaning all the fields and the buttons are moved down a little bit because of the text inserted above. The tricky thing is this: when the focus is in an empty but required field and you click the cancel button, the required-warning is written to the screen but the click-event on the cancel button doesn't fire. I think this is due to the layout shift. The mouse cursor doesn't hover over the button anymore, because the button scrolled down. Has anyone a good idea how i could solve this?

• IE6 HTML control wrapping

  - by astonius

  Is there any way to prevent wrapping across controls in IE6? For example, I have a label and a single select box. The select box width is dynamic (depending on the content). I want the label to always be to the left of the select box. Right now the problem I am having is the select box drops below the label. I have tried using the <nobr> tag as well as CSS word-wrap rules, but because this isn't text the wrapping rules do not apply. The only way I have found for sure to make it work is to place them in a two-column table, but I do not like this solution. Is there any other way?

• Writing datatable to database file, one record at a time in C#

  - by Kevin

  Hi! I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time. Thanks in advance for any help and advice.
