• Winforms control that works like ajax tag-completion

  - by Sargola

  Heya, I want to create a winforms app where you can assign tags to an entity. ofc I want the customer to re-use existing tags a lot. That's why I want to show them the list of tags while they are typing (similar to intellisense in VS and the tags-dropdown even here in stackoverflow ;)) do you have any control(s) in mind that offers this functionality? can I reuse a ComboBox for this? (here I need to drop it down programatically - how?) I want to have the taglist getting input-focus but not lose the mainform-focus, and I want it to be on top over all windows and even range out of the mainform-area (like intellisense in vs) thx!

• Using python to play two sin tones at once

  - by Alex

  Im using python to a sine tone. the tone is based off the computers internal time in minutes, but id like to simultaneously play one based off the second for a harmonized or dualing sound. This is what I have so far can someone point me in the right direction. from struct import pack from math import sin, pi import time def au_file(name, freq, dur, vol): fout = open(name, 'wb') # header needs size, encoding=2, sampling_rate=8000, channel=1 fout.write('.snd' + pack('>5L', 24, 8*dur, 2, 8000, 1)) factor = 2 * pi * freq/8000 # write data for seg in range(8 * dur): # sine wave calculations sin_seg = sin(seg * factor) fout.write(pack('b', vol * 127 * sin_seg)) fout.close() t = time.strftime("%S", time.localtime()) ti = time.strftime("%M", time.localtime()) tis = float(t) tis = tis * 100 tim = float(ti) tim = tim * 100 if name == 'main': au_file(name='timeSound1.au', freq = tim, dur=1000, vol=1.0) import os os.startfile('timeSound1.au')

• getSelection & surroundContents across multiple tags

  - by lethalbody

  Hi, I've got a script that changes the background colour of text that has been selected. However i'm encountering an issue when the text is selected across multiple elements/tags. The code that i've got is: var text = window.getSelection().getRangeAt(0); var colour = document.createElement("hlight"); colour.style.backgroundColor = "Yellow"; text.surroundContents(colour); And the error being output is: Error: The boundary-points of a range does not meet specific requirements. = NS_ERROR_DOM_RANGE_BAD_BOUNDARYPOINTS_ERR Line: 7 I believe this is to do with the getRange() function though i'm not too sure how to proceed since I am a beginner at javascript. Is there any other way I can replicate what I am trying to achieve? Many thanks.

• Horizontal scroll winforms listview

  - by tempy

  Anyone know if its possible to enable horizontal scrolling ONLY in a windows forms listview (viewmode set to large icons). What I want to do is make a listview whose height is sufficient to only show one row of icons, and I don't want to have multiple rows. Just one very long row that a user would have to scroll horizontally to get to out-of-range icons. If I make the listview scrollable then it automatically makes multiple rows and puts in a vertical scrollbar, which I don't want. Thanks in advance!

• How do I set a matplotlib colorbar extents?

  - by Adam Fraser

  I'd like to display a colorbar representing an image's raw values along side a matplotlib imshow subplot which displays that image, normalized. I've been able to draw the image and a colorbar successfully like this, but the colorbar min and max values represent the normalized (0,1) image instead of the raw (0,99) image. f = plt.figure() # create toy image im = np.ones((100,100)) for x in range(100): im[x] = x # create imshow subplot ax = f.add_subplot(111) result = ax.imshow(im / im.max()) # Create the colorbar axc, kw = matplotlib.colorbar.make_axes(ax) cb = matplotlib.colorbar.Colorbar(axc, result) # Set the colorbar result.colorbar = cb If someone has a better mastery of the colorbar API, I'd love to hear from you. Thanks! Adam

• SQL: Need to SUM on results that meet a HAVING statement

  - by Wasauce

  I have a table where we record per user values like money_spent, money_spent_on_candy and the date. So the columns in this table (let's call it MoneyTable) would be: UserId Money_Spent Money_Spent_On_Candy Date My goal is to SUM the total amount of money_spent -- but only for those users where they have spent more than 10% of their total money spent for the date range on candy. What would that query be? I know how to select the Users that have this -- and then I can output the data and sum that by hand but I would like to do this in one single query. Here would be the query to pull the sum of Spend per user for only the users that have spent 10% of their money on candy. SELECT UserId, SUM(Money_Spent), SUM(Money_Spent_On_Candy) / SUM(Money_Spent) AS PercentCandySpend FROM MoneyTable WHERE DATE >= '2010-01-01' HAVING PercentCandySpend > 0.1;

• Ways std::stringstream can set fail/bad bit?

  - by Evan Teran

  A common piece of code I use for simple string splitting looks like this: inline std::vector<std::string> split(const std::string &s, char delim) { std::vector<std::string> elems; std::stringstream ss(s); std::string item; while(std::getline(ss, item, delim)) { elems.push_back(item); } return elems; } Someone mentioned that this will silently "swallow" errors occurring in std::getline. And of course I agree that's the case. But it occurred to me, what could possibly go wrong here in practice that I would need to worry about. basically it all boils down to this: inline std::vector<std::string> split(const std::string &s, char delim) { std::vector<std::string> elems; std::stringstream ss(s); std::string item; while(std::getline(ss, item, delim)) { elems.push_back(item); } if(ss.fail()) { // *** How did we get here!? *** } return elems; } A stringstream is backed by a string, so we don't have to worry about any of the issues associated with reading from a file. There is no type conversion going on here since getline simply reads until it sees a newline or EOF. So we can't get any of the errors that something like boost::lexical_cast has to worry about. I simply can't think of something besides failing to allocate enough memory that could go wrong, but that'll just throw a std::bad_alloc well before the std::getline even takes place. What am I missing?

• google maps, cellid to location

  - by Dels

  According to this sample: http://www.codeproject.com/KB/mobile/DeepCast.aspx It's possible to request a gps coordinate (longitude & latitude) including range when sending cellid information (MCC, MNC, towerid, etc) Can someone tell me the actual parameter to request/post to this address? http://www.google.com/glm/mmap It could be something like this http://www.google.com/glm/mmap?mcc=xxx&mnc=xxx&towerid=xxx And i would like to know what response we would get. I have observe OpenCellid website and they provide some nice API to begin with, but i want to know about that in google map too (since they have more completed database). OpenCellID API

• What alternatives are there to Google App Engine?

  - by Chris Marasti-Georg

  What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

• Passing dynamic CSS to jQuery.animate

  - by harpo

  The documentation of jQuery.animate states that The only required parameter is a map of CSS properties. This map is similar to the one that can be sent to the .css() method, except that the range of properties is more restrictive. So, why does this work $('#con div').css( { top : function(i) { console.log(i); return (i * 500) + 'px'; } } ); and this doesn't? $('#con div').animate( { top : function(i) { console.log(i); return (i * 500) + 'px'; } } ); The console shows that the function is being evaluated for css, but not for animate. Am I missing something? By the way, I'm using 1.4.2.

• How can I create a JTable where the first column is always in the JScrollPane viewport?

  - by voodoogiant

  What's the best way to set up a table in a JScrollPane such that the first column is always on the screen in the same position regardless of horizontal scrolling and overlaps columns that pass underneath? When the scrollbar is at the farthest left, the columns look normal, but as the user scrolls to the right, the secondary columns (2 and on) move underneath the first until the last column appears on the far right of the viewport? I found a sample taken from Eckstein's "Java Swing" book that sort of does this, but it doesn't allow resizing of the first column. I was thinking of some scheme where one JPanel held a horizontal struct and a table holding the secondary columns and another JPanel which floated over them (fixed regardless of scrolling). The struct would be to keep the viewport range constant as the first column floated around. Ideally I could do it with two tables using the same model, but I'm not sure if the whole idea is a naive solution.

• What is a good way to animate UIViews inside UITableViewCell after a callback?

  - by erotsppa

  We couldn't find a way to animate UIViews inside a UITableCell as an action from a callback. Suppose in a scenario where you click on a button on the UITableViewCell and it fires off an asynchronous action to download a picture. Suppose further that when the picture is downloaded we want a UIView in the cell to animate the picture to give user a visual feedback that something new is about to be presented. We couldn't find a way to track down the UIVIew to invoke beginAnimation on because the original cell that the user clicked on might now be used for another row due to the nature of cells being reused when you scroll up and down in the table. In other words we can't keep a pointer to that UITableViewCell. We need to find another way to target the cell and animate it if that row is visible and don't animate if the row is scrolled out of range.

• Write data to an xml file.

  - by Bobby

  My aim is to write an XML file with few tags whose values are the regional language. I'm using Python to do this and using IDLE(Pythong GUI) for programming. While I try to write the words in an xmls file it gives the following error. UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128) For now, I'm not using any xml writer library instead I'm opening a file "test.xml" and writing the data into it. This error is encountered by the line: f.write("\t\" + data + "\"). If I replace the above write statement with print statement then it prints the data properly on Python Shell. I'm reading the data from an excel file which is not in the UTF8,16, or 32 encoding formats. Its in some other format. cp1252 is reading the data properly. Any help in getting this data writtent oan xml would be highly appreciated. Thanks in advance. Bob

• Maximum page fetch with maximum bandwith

  - by Ehsan

  Hi I want to create an application like a spider I've implement fetching page as the following code in multi-thread application but there is two problem 1) I want to use my maximum bandwidth to send/receive request, how should I config my request to do so (Like Download Accelerator application and the like) cause I heard the normal application will use 66% of the available bandwidth. 2) I don't know what exactly HttpWebRequest.KeepAlive do, but as its name implies I think i can create a connection to a website and without closing the connection sending another request to that web site using existing connection. does it boost performance or Im wrong ?? public PageFetchResult Fetch() { PageFetchResult fetchResult = new PageFetchResult(); try { HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(URLAddress); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Uri requestedURI = new Uri(URLAddress); Uri responseURI = resp.ResponseUri; string resultHTML = ""; byte[] reqHTML = ResponseAsBytes(resp); if (!string.IsNullOrEmpty(FetchingEncoding)) resultHTML = Encoding.GetEncoding(FetchingEncoding).GetString(reqHTML); else if (!string.IsNullOrEmpty(resp.CharacterSet)) resultHTML = Encoding.GetEncoding(resp.CharacterSet).GetString(reqHTML); req.Abort(); resp.Close(); fetchResult.IsOK = true; fetchResult.ResultHTML = resultHTML; } catch (Exception ex) { fetchResult.IsOK = false; fetchResult.ErrorMessage = ex.Message; } return fetchResult; }

• Sending multipart response for downloads in Zend Framework

  - by takeshin

  I'm sending files in action helper for downloads (in parts if needed) like this: ... $response->sendHeaders(); $chunksize = 1 * (1024 * 1024); $bytesSent = 0; if ($httpRange) { fseek($file, $range); } while(!feof($file) && (!connection_aborted() && ($bytesSent < $newLength)) ) { $buffer = fread($file, $chunksize); // $response->appendBody($buffer); // this would be better print($buffer); flush(); $bytesSent += strlen($buffer); } fclose($file); I suspect that better way would be to make use of $response object instead of print. Which is the recommended way to send big response objects using Zend Framework?

• Could the UIHint attribute accept a property of the current class ?

  - by user252160

  I found the follwing code in MSDN . How can I change this "UnitsInStock" with a value that my Product class has. For instance, Product has a FieldType property which has a string property called Name. I'd like to use that FieldType.Name property instead of hardcoding with a string. However, I cannot specify "this", or the current instance as an argument of the UIHint attribute . Please, help using System; using System.Web.DynamicData; using System.ComponentModel.DataAnnotations; [MetadataType(typeof(ProductMetadata))] public partial class Product { } public partial class ProductMetadata { [UIHint("UnitsInStock")] [Range(100, 10000, ErrorMessage = "Units in stock should be between {1} and {2}.")] public object UnitsInStock; }

• Time zone for Force.com API fiscal date literals?

  - by Nick

  I have a question about fiscal date literals in the Force.com API (http://www.salesforce.com/us/developer/docs/api/Content/sforce_api_calls_soql_select_dateformats.htm): For which time zone are date ranges calculated? For example, suppose we execute the query: SELECT Id FROM Opportunity WHERE CloseDate = THIS_FISCAL_QUARTER where, according to our company's fiscal settings, THIS_FISCAL_QUARTER runs from Jan 1 to Mar 31. Does the range for THIS_FISCAL_QUARTER use... the user's time zone? For example, if the user's time zone is GMT-8, THIS_FISCAL_QUARTER = Jan 1 00:00 GMT-8 to Mar 31 23:59 GMT-8 (or Jan 1 08:00 UTC to Mar 31 07:59 UTC) the company's default time zone (according to the company profile)? For example, if the company's default time zone is GMT-8, THIS_FISCAL_QUARTER = Jan 1 00:00 GMT-8 to Mar 31 23:59 GMT-8 (or Jan 1 08:00 UTC to Mar 31 07:59 UTC) UTC? THIS_FISCAL_QUARTER = Jan 1 00:00 UTC to Mar 31 23:59 UTC something else?

• populate a comboBox in Griffon App dynamically

  - by kulkarni

  I have 2 comboBoxes in my View of Griffon App (or groovy swingBuilder) country = comboBox(items:country(), selectedItem: bind(target:model, 'country', value:model.country), actionPerformed: controller.getStates) state = comboBox(items:bind(source:model, sourceProperty:'states'), selectedItem: bind(target:model, 'state', value:model.state)) The getStates() in the controller, populates @Bindable List states = [] in the model based on the country selected. The above code doesn't give any errors, but the states are never populated. I changed the states from being List to a range object(dummy), it gives me an error MissingPropertyException No such property items for class java.swing.JComboBox. Am I missing something here? There are a couple of entries related to this on Nabble but nothing is clear. The above code works if I had a label instead of a second comboBox.

• Multilangual Unicode rendering in opengl

  - by sum1stolemyname

  Hi Folks, I have to extend an OpenGL-Rendering System to support international characters (especially Hebrew, Arabic and cyrillic). Development Platform is Windows(XP|Vista|7), Alas using Embercardero Delphi 2010. I currently use wglOutLineFont(...) to build my font's display list and glCallLists(length(m_Text), UNSIGNED_SHORT, PWchar(m_Text) ) to render my strings. While this is feasable for Latin-1 Characters, building the full unicode character set in advanced is pretty time-consuming (about 8.5 minutes on my machine), so i am looking for a more efficient solution. I thought about limiting the range from u+0020 - u+077f (latin, greek, cyrillic, arbaic and hebrew) to include just the glyphs i need, but that would just be a solution for my current needs, and will become insufficent once other encoding is needed. On the upside, i do not have to worry about left-to right or right-to left direction as our application can handle this already. I would expect this to be a well-known problem, so i would like to ask if there is any reference material on this on the web, or if you could share some insight on this?

• On-the-fly lossless image compression

  - by geschema

  I have an embedded application where an image scanner sends out a stream of 16-bit pixels that are later assembled to a grayscale image. As I need to both save this data locally and forward it to a network interface, I'd like to compress the data stream to reduce the required storage space and network bandwidth. Is there a simple algorithm that I can use to losslessly compress the pixel data? I first thought of computing the difference between two consecutive pixels and then encoding this difference with a Huffman code. Unfortunately, the pixels are unsigned 16-bit quantities so the difference can be anywhere in the range -65535 .. +65535 which leads to potentially huge codeword lengths. If a few really long codewords occur in a row, I'll run into buffer overflow problems.
