• Help with force close occurrences in my app

  - by Ken

  This is the last issue with this app. Periodic force close situations. I think something should be on another thread but I'm not sure what. Anyway, I can always count on a freeze on first install. If I wait, eventually (maybe 10 seconds) the app comes around, maybe more. here is an excerpt from logcat--the three lines occur after full layout is displayed and I attempt to touch a [game] 'peg' which should spawn a sprite, but the freeze occurs there. Can anybody tell what the issue might be?: I/System.out( 279): TouchDown (17.0,106.0) I/System.out( 279): checking (17,106 I/System.out( 279): hit for bounds Rect(3, 98 - 32, 130) [FREEZE BEGINS] W/webcore ( 279): Can't get the viewWidth after the first layout W/WindowManager( 60): Key dispatching timed out sending to com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree W/WindowManager( 60): Previous dispatch state: null W/WindowManager( 60): Current dispatch state: {{null to Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false} @ 1295232880017 lw=Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false} lb=android.os.BinderProxy@440523b8 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false}}} I/Process ( 60): Sending signal.

• Design pattern for parsing data that will be grouped to two different ways and flipped

  - by lewisblackfan

  I'm looking for an easily maintainable and extendable design model for a script to parse an excel workbook into two separate workbooks after pulling data from other locations like the command line, and a database. The high level details are as follows. I need to parse an excel workbook containing a sheet that lists unique question names, the only reliable information that can be parsed from the question name is the book code that identifies the title and edition of the textbook the question is associated with, the rest of the question name is not standardized well enough to be reliably parsed by computer. The general form of the question name is best described by the following regular expression. '^(\w+)\s(\w{1,2})\.(\w{1,2})\.(\w{1,3})\.(\w{1,3}\.)*$' The first sub-pattern is the book code, the second sub-pattern is 90% of the time the chapter, and the rest of the sub-patterns could be section, problem type, problem number, or question type information. There is no simple logic, at least not one I can find. There will be a minimum of three other columns in this spreadsheet; one column will be the chapter the question is associated with, the second will be the section within the chapter the question is associated with, and the third will be some kind of asset indicated by a uniform resource locator. 1 | 1 | qname1 | url | description | url | description ... 1 | 1 | qname2 | url | description 1 | 1 | qname3 | url | description | url | description | url | The asset can be indicated by a full or partial uniform resource locator, the partial url will need to be completed before it can be fed into the application. There theoretically could be no limit to the number of asset columns, the assets will be grouped in columns by type. Some times additional data will have to be retrieved from a database or combined with the book code before the asset url is complete and can be understood by the application that will be using the asset. The type is an abstraction, there are eight types right now, each with their own logic in how the uniform resource locator is handled and or completed, and I have to add a new type and its logic every three or four months. For each asset url there is the possibility of a description column, a character string for display in the application, but not always. (I've already worked out validating the description text, and squashing MSs obscure code page down to something 7-bit ascii can handle.) Now that all the details are filled-in I can get to the actual problem of parsing the file. I need to split the information in this excel workbook into two separate workbooks. The first workbook will group all the questions by section in rows. With the first cell being the section doublet and the rest of the cells in the row are the question names. 1.1 | qname1 | qname2 | qname3 | qname4 | 1.2 | qname1 | qname2 | qname3 | 1.3 | qname1 | qname2 | qname3 | qname4 | qname5 There is no set number of questions for each section as you can see from the above example. The second workbook is more complicated, there is one row per asset, and question names that have more than one asset will be duplicated. There will be four or five columns on this sheet. The first is the question name for the asset, the second is a media type used to select the correct icon for the asset in the application, the third is string representing the asset type, the four is the full and complete uniform resource locator for the asset, and the fifth columns is the optional text description for the asset. q1 | mtype1 | atype1 | url | description q1 | mtype2 | atype2 | url | description q1 | mtype2 | atype3 | url | description q2 | mtype1 | atype1 | url | description q2 | mtype2 | atype3 | url | description For the original six types I did have a script that parsed the source excel workbook into the other two excel workbooks, and I was able to add two more types until I ran aground on the implementation of the ninth type and tenth types. What broke my script was the fact that the ninth type is actually a sub-type of one of the original six, but with entirely different logic, and my mostly procedural script could not accommodate without duplicating a lot of code. I also had a lot of bugs in the script and will be writing the test first on this time around. I'm stuck with the format for the resulting two workbooks, this script is glue code, development went ahead with the project without bothering to get a complete spec from the sponsor. I work for the same company as the developers but in the editorial department, editorial is co-sponsor of the project, and am expected to fix pesky details like this (I'm foaming at the mouth as I type this). I've tried factories, I've tried different object models, but each resulting workbook is so different when I find a design that works for generating one workbook the code is not really usable for generating the other. What I would really like are ideas about a maintainable and extensible design for parsing the source workbook into both workbooks with maximum code reuse, and or sympathy.

• Adding text over existing PDFs using reportlab

  - by Shane

  I'm interested in filling out existing PDF forms programatically. All I really need to do is pull information from user input and then place the appropriate text over an existing PDF in the appropriate locations. I can already do this with reportlab by feeding the same sheet of paper into a printer, twice, but this just really rubs me the wrong way. I'm tempted to just personally reverse engineer each existing PDF and draw every line and character myself before adding the user-inputted text, but I wanted to check to see if there was an easy way to take an existing PDF and set it as a background for some extra text. I'd really prefer to use python as it's the only language I feel comfortable with. I also realize that I could just scan the document itself and use the resulting raster image as a background, but I would prefer the precision of vector graphics. It seems like ReportLab has a commercial product with this functionality, and the specific function I'm looking for is in it (copyPages) - but it seems like overkill to pay for a 4 figure product for a single, simple function for a nonprofit use.

• CSS sprites navigation and User with image disabled.....

  - by metal-gear-solid

  I made a css menu with css sprites but the problem is with sprite we don't use inline image we use in background only so if images are disabled in browser then nothing will show . any solution for this ? For example : See this menu and turn off images : http://line25.com/wp-content/uploads/2009/css-menu/demo/demo.html (it will not be seen if images are disabled in browser) this menu is against on this quote Ensure your website works with images disabled Creating a site that relies too heavily on images is never a good idea. Although almost a thing of the past, there are still users who run at very low internet speeds. Also, if a user needs to—for whatever reason—disable images, can they still access all the content they need to? http://csswizardry.com/quick-tips/#tip-02 Shouldn't we use this type of navigation.

• Software to Mind Map Dependencies

  - by Alix Axel

  I'm putting together something I'll soon release as OSS and I wanted to make a map of dependencies to get a clearer idea of the big picture. I ended up making the mind map myself using pen and paper: This is something I wish I could do more often, but mapping bigger projects manually is too troublesome (and virtually impossible due to the size of the sheet) and since I can't find any mind mapping software that fits my needs and allows me to display the map in the visual structure I want I often leave the mind maps in my mind alone, no visual representation whatsoever... Can anyone suggest a good mind mapping software that allows me to do something like the above? I've tried FreeMind and XMind so far but their visual structure is too rigid for what I need.

• How to manipulate and print a chart in MS Excel from AppleScript?

  - by Stu Thompson

  With an existing chart in a MS Excel for Mac 2008, in AppleScript, I am trying to do two things: Rotate a 3D chart 1° Save the chart as a image (png) From what I've found on the Intertubes, it seems possible. But AppleScript's awkward verbosity and the lack of non-trivial MS Excel AppleScript examples on the web are too much for me to overcome. Just for the saving part, this is what I have so far: tell application "Microsoft Excel" activate object worksheet "iozone-16" set cht to chart object 1 of active sheet tell cht #save as chart object [picture type enumeration] [file name Unicode text] #Argh!!! end tell end tell The 'rotate 1°' task seems to involve "internal objects", but that is as far as I've gotten.

• How to pass a string containing both single and double quotes as a parameter to XSLT in PHP?

  - by Boaz

  Hi, I have a simple PHP-based XSLT trasform code that looks like that: $xsl = new XSLTProcessor(); $xsl->registerPHPFunctions(); $xsl->setParameter("","searchterms", $searchterms); $xsl->importStylesheet($xslDoc); echo $xsl->transformToXML($doc); The code passes the variable $searchterms, which contains a string, as a parameter to the XSLT style sheet which in turns uses it as a text: <title>search feed for <xsl:value-of select="$searchterms"/></title> This works fine until you try to pass a string with mixes in it, say: $searchterms = '"some"'." text's quotes are mixed." In that point the XSLT processor screams: Cannot create XPath expression (string contains both quote and double-quotes) What is the correct way to safely pass arbitrary strings as input to XSLT? Note that these strings will be used as a text value in the resulting XML and not as an XPATH paramater. Thanks, Boaz

• How to keep my functions (objects/methods) 'lean and mean'

  - by Michel

  Hi, in all (Agile) articles i read about this: keep your code and functions small and easy to test. How should i do this with the 'controller' or 'coordinator' class? In my situation, i have to import data. In the end i have one object who coordinates this, and i was wondering if there is a way of keeping the coordinator lean(er) and mean(er). My coordinator now does the followling (pseudocode) //Write to the log that the import has started Log.StartImport() //Get the data in Excel sheet format result = new Downloader().GetExcelFile() //Log this step Log.LogStep(result ) //convert the data to intern objects result = new Converter().Convertdata(result); //Log this step Log.LogStep(result ) //write the data result = Repository.SaveData(result); //Log this step Log.LogStep(result ) Imho, this is one of those 'know all' classes or at least one being 'not lean and mean'? Or, am i taking this lean and mean thing to far and is it impossible to program an import without some kind of 'fat' importer/coordinator? Michel

• VBA - Create ADODB.Recordset from the contents of a spreadsheet

  - by robault

  Hello, I am working on an Excel application that queries a SQL database. The queries can take a long time to run (20-40 min). If I've miss-coded something it can take a long time to error or reach a break point. I can save the results to a sheet fine, it's when I am working with the record sets that things can blow up. Is there a way to load the data into a ADODB.Recordset when I'm debugging to skip querying the database (after the first time)? Would I use something like this? http://stackoverflow.com/questions/2086234/query-excel-worksheet-in-ms-access-vba-using-adodb-recordset

• as3 swc component preview through code

  - by David

  I am developing an as3 swc-based component that populates its contents entirely through actionscript in the constructor (e.g. sprite.graphics.lineTo...). When I drag the component onto the stage, it is empty. If I export my movie, everything works perfectly, but I also need the live preview to work. I could get around this with a placeholder graphic, but I would much rather leave it purely as code. Is there any way to get around this? Thanks, David.

• using Control.tabs for prototype.js in Rails

  - by Elliot

  Hey everyone, I've been trying to use http://livepipe.net/control/tabs to get some javascript tabs up and running on my rails up. I'm really just trying to figure out how to install this... and I don't see how I'm running into any issues at all. Here are the steps I've taken: put tabs.js in my scripts folder made sure the layout is including all javascript files then I copied in the code for example 1, as well as the CSS from the page's style sheet. I don't get an error, but it just doesn't work. Both tabs are displayed... Any ideas?

• Can't see drop down list in Excel VBA

  - by Ten Ton Gorilla

  I've created a very simple drop down list in excel. It holds a sequence of integers loaded from a cell range (years). I need to read the selected value in vba. However I can't even seem to find the control! I've tried CboYear Sheet2.CboYear Worksheets("SheetName").CboYear etc. etc. From everywhere in VBA this control just doesn't exist. All the tutorial I find seem to assume that using just the control name will work. I've tried the code in the sheet itself, the workbook, and a module, no luck.

• Determining actual args an Excel UDF was called with.

  - by Frederick

  I'm adding a user defined function to Excel with varargs-based signature in C++: XLFUNCTIONIMP(MyFunction)(...); When Excel calls MyFunction, it passes it 30 arguments regardless of how many the user entered in the sheet. The extraneous ones are blank strings. MyFunction, however, is designed to accept empty string arguments. As a result, I cannot tell valid empty strings apart from the extraneous ones sent by Excel. A solution could be to obtain the contents of the actual cell where the user entered the function. However, I can't find a way of doing that from within the implementation of my function. Could someone please suggest a way out?

• Good way to make animations with cocos2d?

  - by Johnny Oin

  Hi there, I'm making a little iphone game, and I would get some clues. Let's imagine: Two background sprites moving pretty fast from right to left, and moving up and down with accelerometer. I guess I can't use animations here, cause the movement of the background is recalculated at each frame. So I use a schedule with an interval of 0.025s and move my sprites at each clock with a : sprite.position = ccp(x, y); So here is my problem: the result is laggy, with only these two sprites. I tried both declaring sprites in the header, and getting them with CCNodes and Tags. It's quite the same. So if someone can give me a hint on what is the best way to do that, that would be so nice. I wonder if the problem can't be the fact that sprites are moving very fast, but i'm not sure. Anyway, thanks for your time. J.

• How can I loop through every letter in MS Word using VBA?

  - by Behrooz Karjooravary

  I have about 100 ms word documents which include transliteration of foreign names. The author of these docs used a special font called e2 which has about a dozen special transliteration characters (all of which are available in ms sans serif font). I would like to loop through every letter of the document and whenever the font = e2 i would like to loop through the dozen letters (it's easy to guess what they are) and replace them with a Microsoft Sans Serif equivalent. But I can't figure out how you can loop though letters. Is that doable like looping through cells in an excel spread sheet?

• excel 2007 vba: how to refer to HPageBreaks

  - by notnot

  I'm trying to write a macro which can look into the list of horizontal page breaks that a worksheet keeps, and it seems like HPageBreaks should be exactly that. I can add or remove page breaks from it, but I can't seem to isolate the collection itself to look at its contents. Even adding a watch and looking at ActiveSheet.HPageBreaks just brings up a generic looking object with a count field equal to 0 regardless of existing page breaks. I'm really confused about this now. Is there any way to look into the existing page breaks within a sheet? A listing of what rows they occur on/between would be great.

• DataTable to Object collection

  - by Kenneth Cochran

  I'm working on a data import feature and I've been able to load an excel sheet into a DataTable using Ado.NET with the MSJet db engine. I created a simple one-to-one mapping dialog, in which the user drags column headings from their spreadsheet to a list of object properties. What's stumping me is how to turn each DataRow into a business object. Is there an easy way to do this? If there is a better way than using a DataTable as a middleman I'm open to suggestion? I use NHibernate extensively through out the rest of my program but I couldn't find any attempts to map to an excel spreadsheet. I went with a DataTable because the technique was well documented.

• Reading string value from Excel with HSSF but it's double

  - by egaga

  Hi, I'm using HSSF-POI for reading excel data. The problem is I have values in a cell that look like a number but really are strings. If I look at the format cell in Excel, it says the type is "text". Still the HSSF Cell thinks it's numeric. How can I get the value as a string? If I try to use cell.getRichStringValue, I get exception; if cell.toString, it's not the exact same value as in Excel sheet. Thanks! edit: until this gets resolved, I'll use new BigDecimal(cell.getNumericCellValue()).toString()

• How can I use a Shader in XNA to color single pixels?

  - by George Johnston

  I have a standard 800x600 window in my XNA project. My goal is to color each individual pixel based on a rectangle array which holds boolean values. Currently I am using a 1x1 Texture and drawing each sprite in my array. I am very new to XNA and come from a GDI background, so I am doing what I would have done in GDI, but it doesn't scale very well. I have been told in another question to use a Shader, but after much research, I still haven't been able to find out how to accomplish this goal. My application loops through the X and Y coordinates of my rectangular array, does calculations based on each value, and reassigns/moves the array around. At the end, I need to update my "Canvas" with the new values. A smaller sample of my array would look like: 0,0,0,0,0,0,0 0,0,0,0,0,0,0 0,0,0,0,0,0,0 1,1,1,1,1,1,1 1,1,1,1,1,1,1 How can I use a shader to color each pixel?

• Most common C# bitwise operations

  - by steffenj

  For the life of me, I can't remember how to set, delete, toggle or test a bit in a bitfield. Either I'm unsure or I mix them up because I rarely need these. So a "bit-cheat-sheet" would be nice to have. For example: flags = flags | FlagsEnum.Bit4; // Set bit 4. or if ((flags == FlagsEnum.Bit4)) == FlagsEnum.Bit4) // Is there a less verbose way? Can you give examples of all the other common operations, preferably in C# syntax using a [Flags] enum?

• Using "Show values as" option in Excel 2007 pivot table when source is SSAS cube?

  - by Brad

  I have an Excel 2007 pivot table showing "Year" across the top and "Month" down the side. What I am trying to do is represent the values as "% Difference" from the same month of the previous year. (Ex. If Jan-07 is $100,000 and Jan-08 is $120,000, I would like Jan-08 to show '20%'). However, every time I try to do this (using the "Show values as" tab of Value Field Settings) all of my numbers go to '#N/A'. Is there a way to do this using an Analysis Services cube as the data source? When I do this exact same thing using data on a different sheet as the data source for the pivot table, it works fine. Thanks in advance for any insight into this.

• Templated Control databinding to custom properties

  - by Dan Wray

  Is there some trick that I'm missing here? I've created a templated control, very simple. One single property on it, and I'd like to databind from the (viewmodel/datacontext of the) page in which it's hosted to a custom property on the control. The property will eventually be a vector type object, defining the position of the control, however in an attempt to get this to work I've tried reducing it to a basic string property. Each time I'm faced with "Set property 'SimpleGame.Classes.Sprite.Property' threw an exception.". I can't even catch the exception in a debug session, the set property code is not being executed. Do I need to use a dependency / attached property or something? I wouldn't have thought so...

• How to embed images in a single HTML / PHP file?

  - by Tatu Ulmanen

  Hi, I am creating a lightweight, single-file database administration tool and I would like to bundle some small icons with it. What is the best way to embed images in a HTML/PHP file? I know a method using PHP where I would call the same file with a GET parameter that would output hardcoded binary data with the correct header, but that seems a bit complicated. Can I use something to pass the image directly in a CSS background-image declaration? This would allow me to utilize the CSS sprite technique. Browser support isn't an issue here, so more exotic methods are welcome also. EDIT Does someone have a link/example to how to generate Data URL's properly with PHP? I'd figure echo 'data:image/png;base64,'.base64_encode(file_get_contents('image.png')) would suffice but I could be wrong.
