  • Setting EditText imeOptions to actionNext has no effect

    - by Katedral Pillon
    I have a fairly complex (not really) xml layout file. One of the views is a LinearLayout (v1) with two children: an EditText(v2) and another LinearLayout(v3). The child LinearLayout in turn has an EditText(v4) and an ImageView(v5). For EditText v2 I have imeOptions as android:imeOptions="actionNext" But when I run the app, the keyboard's return does not check to next and I want it to change to next. How do I fix this problem? Also, when user clicks next, I want focus to go to EditText v4. I do I do this? For those who really need to see some code: <LinearLayout android:id="@+id/do_txt_view" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/col6" android:orientation="vertical" android:visibility="gone" > <EditText android:id="@+id/gm_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="5dp" android:background="@drawable/coldo_text" android:hint="@string/enter_title" android:maxLines="1" android:imeOptions="actionNext" android:padding="5dp" android:textColor="pigc7" android:textSize="ads2" /> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="horizontal" > <EditText android:id="@+id/rev_text" android:layout_width="0dp" android:layout_height="match_parent" android:layout_gravity="center_vertical" android:layout_margin="5dp" android:layout_weight="1" android:background="@drawable/coldo_text" android:hint="@string/enter_msg" android:maxLines="2" android:padding="5dp" android:textColor="pigc7" android:textSize="ads2" /> <ImageView android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="center_vertical" android:background="@drawable/colbtn_r” android:clickable="true" android:onClick=“clickAct” android:paddingLeft="5dp" android:paddingRight="5dp" android:src="@drawable/abcat” /> </LinearLayout> </LinearLayout>

  • Iterating through controls on a Windows Form

    - by icemanind
    I seem to have some weird issue going on that I am sure will turn out to be a simple thing. I have a Windows Form and on the form I have 1 panel called MainPanel and inside MainPanel, I got another panel with a button inside and a label that is inside MainPanel, but not in the second panel. 2 controls. What I am trying to do is copy all the controls inside MainPanel over to another panel object. I am using the following C# code to do this: GUIPanel gp = new GUIPanel(); foreach (System.Windows.Forms.Control ctrl in gp.Controls["MainPanel"].Controls) { m_OptionsControl.Controls.Add(ctrl); } When I run this code, it copies over the panel with the button, but not the label. What's even more odd is when I set a breakpoint and run it through the debugger, and I type "?gp.Controls["MainPanel"].Controls.Count" in the immediate window, it returns 2, just like it should. However, when stepping through the code, it only executes the foreach loop once. What am I missing here?

  • How to avoid game rendering component circular references?

    - by CodexArcanum
    I'm working on a simple game design, and I wanted to break up my game objects into more reusable components. But I'm getting stuck on how exactly to implement the design I have in mind. Here's an example: I have a Logger object, whose job is simply to store a list of messages and render them to screen. You know, logging. Originally the Logger just held the list, and the game loop rendered it's contents. Then I moved the rendering logic into the Logger.Draw() method, and now I want to move it further into a LoggerRenderer object. In effect, I want to have the game loop call RenderAll, which will then call Logger.Render, which will in turn call the LoggerRenderer.Render and finally output the text. So the Logger needs to contain a Renderer object, but the Renderer needs access to the Logger's state (the message queue) in order to render. How do I resolve that? Should I be passing in the message queue and other state information explicitly to the Render method? Or should the game loop be calling the Renderer directly and it links back to the logger, but the RenderAll method never actually sees the logger object itself? This feels kind of like Command pattern, but I'm botching it up terribly.

  • Passing variables across a multi page form in php

    - by Chris
    Forgive me as I am a newbie. I have a multi page form in which I am using $_SESSIONS to record the variables. <?php session_start(); foreach ( $_POST as $key=>$value ) { if ( $key!="submit" ) { $value= htmlentities(stripslashes(strip_tags($value))); $_SESSION[$key] = $value; } }` I have two problems actually. When I get to a checkform.php that I made that prints out the variables, The variables from page 1 doesn't show up even though that code listed above is on each page. I am using Firefox web developers tool to disable cookies and in the php ini, I altered session.use_trans_sid to 1 to turn it on. For the final page on my checkform.php I print_r($_POST) for the final page which works fine. Why doesn't variables from page 1 not show up? What am I missing? The 2nd problem is that when I print_r($_SESSION), some fields, specifically the checkbox arrays, print as [payment] => Array [agerange] => Array [meals] => Array [mealtypes] => Array What am I missing?

  • Logical file not working for SUBFILE/SETLL?

    I'm using three logical file with different Record Format where on the first subfile I'm using LF1 and LF2 where on the first subfile I cannot use *LOVAL SETLL it will give me Run Time Error. not sure why? then the program will lead me to second subfile and I'm using LF3 it seems fine. but then If I back to first subfile the subfile turn to blanks.???? why? this my subroutine for building my subfile: C CLRSR BEGSR C EVAL *IN55='0' C WRITE USQLSCTL C EVAL *IN55='1' C ENDSR C* C*BUILDING SUBFILE C BLDSR BEGSR C *LOVAL SETLL USRLGX C EVAL RECNO=0 C EXSR TMISR1 C EXSR REDSR1 C DOW NOT %EOF C IF USRID<>IDD C EXSR MVESR C EXSR DIMSR C MOVE USRID IDD C EVAL RECNO=RECNO+1 C WRITE USQLS C ENDIF C EXSR TMISR1 C EXSR REDSR1 C ENDDO C ENDSR and the related subroutine C TMISR1 BEGSR C READ USRLGX C MOVE USRTI MINTI C ENDSR C REDSR1 BEGSR C READ USRLG C MOVE USRTO MAXTO C ENDSR 6 n the LF I used is USRLG and USRLGX. where both LF refer to the same record format. but each LF has different sorted order. *record format has been RENAME on F-Spec I have this two problem which is: I only can use *LOVAL setll logical-file once only. n the result for coding above sometime it will give result for UserTimeIn some time it equals to blanks.(000000)

  • Trouble with LINQ databind to GridView and RowDataBound

    - by Michael
    Greetings all, I am working on redesigning my personal Web site using VS 2008 and have chosen to use LINQ to create by data-access layer. Part of my site will be a little app to help manage my budget better. My first LINQ query does successfully execute and display in a GridView, but when I try to use a RowDataBound event to work with the results and refine them a bit, I get the error: The type or namespace name 'var' could not be found (are you missing a using directive or an assembly reference?) This interesting part is, if I just try to put in a var s = "s"; anywhere else in the same file, I get the same error too. If I go to other files in the web project, var s = "s"; compiles fine. Here is the LINQ Query call: public static IQueryable pubGetRecentTransactions(int param_accountid) { clsDataContext db; db = new clsDataContext(); var query = from d in db.tblMoneyTransactions join p in db.tblMoneyTransactions on d.iParentTransID equals p.iTransID into dp from p in dp.DefaultIfEmpty() where d.iAccountID == param_accountid orderby d.dtTransDate descending, d.iTransID ascending select new { d.iTransID, d.dtTransDate, sTransDesc = p != null ? p.sTransDesc : d.sTransDesc, d.sTransMemo, d.mTransAmt, d.iCheckNum, d.iParentTransID, d.iReconciled, d.bIsTransfer }; return query; } protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { this.prvLoadData(); } } internal void prvLoadData() { prvCtlGridTransactions.DataSource = clsMoneyTransactions.pubGetRecentTransactions(2); prvCtlGridTransactions.DataBind(); } protected void prvCtlGridTransactions_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { var datarow = e.Row.DataItem; var s = "s"; e.Row.Cells[0].Text = datarow.dtTransDate.ToShortDateString(); e.Row.Cells[1].Text = datarow.sTransDesc; e.Row.Cells[2].Text = datarow.mTransAmt.ToString("c"); e.Row.Cells[3].Text = datarow.iReconciled.ToString(); }//end if }//end RowDataBound My googling to date hasn't found a good answer, so I turn it over to this trusted community. I appreciate your time in assisting me.

  • Tips on managing dependencies for a release?

    - by Andrew Murray
    Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.

  • Converting timestamp to time ago in php e.g 1 day ago, 2 days ago...

    - by cosmicbdog
    hi everyone, i am trying to convert a timestamp of the format: 2009-09-12 20:57:19 and turn it into something like '3 minutes ago' with php. I found a useful script to do this, but I think its looking for a different format to be used as the time variable. The script I'm wanting to modify to work with this format is: function _ago($tm,$rcs = 0) { $cur_tm = time(); $dif = $cur_tm-$tm; $pds = array('second','minute','hour','day','week','month','year','decade'); $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600); for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]); $no = floor($no); if($no <> 1) $pds[$v] .='s'; $x=sprintf("%d %s ",$no,$pds[$v]); if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0)) $x .= time_ago($_tm); return $x; } I think on those first few lines its trying to do something that looks like this (different date format math): $dif = 1252809479 - 2009-09-12 20:57:19; How would I go about converting my timestamp into that (unix?) format?

  • Shutdown and WakeUp Script C#

    - by Stephen Murby
    Hiya I am very new to C#, infact this is basically my first task set by work whilst i learn the language. Yes i am also new to programming, be gentle :). Context: My script needs to query active directory, grab of OU's and put them to a combo box in a form. Next query ActDir for a list of machines in a selected OU (Done this in a vbscript already) Next query the machines in turn for there IP, and MAC addresses.(Done this in a vbscript already) Next needs to shut those machines down(Done this in a vbscript already) and dump all the machine and NIC info to a txt file The other half of the script grabs the info for the machines out of the text file and sends them a magic packet to wake them up. The shutdown section i have already written a VBscript for, but decided it wasn't future prrof, and i was learninc C# at home, so figured it was the best option to start over with. Im not looking for anyone to write this for me, but if anyone had any pointers on where to go for information etc. . . It would be more than appreciated :)

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • Categories of tags

    - by Peter Rowell
    I'm starting a pro bono project that is the web interface to the world's largest collection of lute music and it's a challenging collection from several points of view. The pieces are largely from 1400 to 1600, but they range from the mid-1200's to present day. Needless to say, there is tremendous variability in how the pieces are categorized and who they are attributed to. It is obvious that any sort of rigid, DB-enforced hierarchy isn't going to work with this collection, so my thoughts turn to tags. But not all tags are the same. I'll have tags that represent a person/role (composer, translator, entabulator, etc.), tags that represent the instrument(s) the piece in written for, and tags that represent how the piece has been classified by any one of half a dozen different classification systems used over the centuries. We will be using a semi-controlled tag vocabulary to prevent runaway tag proliferation (e.g. del.icio.us), but I want to treat the tags as belonging to different groups. People tags should not be offered when the editor is doing instrument tagging, etc. Has anyone done something like this? I have several ways I can think of to do it, but if there is an existing system that is well-done it would save me time implementing/debugging. FWIW: This is a Django system and I'm looking at starting with Django-tagging and then hacking from there, possibly adding a category field or ...

  • Looping through a SimpleXML object, or turning the whole thing into an array.

    - by Coffee Cup
    I'm trying to work out how to iterate though a returned SimpleXML object. I'm using a toolkit called Tarzan AWS, which connects to Amazon Web Services (SimpleDB, S3, EC2, etc). I'm specifically using SimpleDB. I can put data into the Amazon SimpleDB service, and I can get it back. I just don't know how to handle the SimpleXML object that is returned. The Tarzan AWS documentation says this: Look at the response to navigate through the headers and body of the response. Note that this is an object, not an array, and that the body is a SimpleXML object. Here's a sample of the returned SimpleXML object: [body] = SimpleXMLElement Object ( [QueryWithAttributesResult] = SimpleXMLElement Object ( [Item] = Array ( [0] = SimpleXMLElement Object ( [Name] = message12413344443260 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = john ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is a message. ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334444 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413344443260 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.1 ) ) ) [1] = SimpleXMLElement Object ( [Name] = message12413346907303 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = fred ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is another message ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334690 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413346907303 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.2 ) ) ) ) So what code do I need to get through each of the object items? I'd like to loop through each of them and handle it like a returned mySQL query. For example, I can query SimpleDB and then loop though the SimpleXML so I can display the results on the page. Alternatively, how do you turn the whole shebang into an array? I'm new to SimpleXML, so I apologise if my questions aren't specific enough.

  • Deploying .NET COM dll, getting error (0x80070002)

    - by Brett
    I have a .NET COM assembly I am attempting to deploy to a web server (IIS 6 Win 2003). We have successfully deployed this assembly to our test environment, but the production environment is not working. The assembly is being called from a classic ASP page. Every time that page tries to initialize the assembly with “Set LTMRender = CreateObject("LTMRender.Render")”, I get an error “Error Type:, (0x80070002)”. This error seems to indicate a permission denied, or file not found type problem. I created a test app to see if the assembly works outside of the web page. The .exe initializes the assembly, and then makes a call designed to fail which in turn causes the assembly to produce a log file. It works if I run the .exe in the same folder as the assembly, but fails if I run it elsewhere. For some reason, the assembly is not accessible from outside it’s folder. I can’t figure out why this won’t work. Things I have confirmed: The deployment folder has adequate permissions. We have confirmed that the folder the assembly in installed in has the correct permissions for all the necessary user accounts. The Assembly is signed with a strong name, and was registered with regasm.exe C:_WebSites\LTMRender\LTMRender.dll /codebase /tlb:C:_WebSites\LTMRender\LTMRender.tlb. Regasm reported success. The Assembly has the attribute and relevant GUID’s set correctly. Any tips? EDIT We ran filemon against my testapp.exe and it seems to have indicated what the problem is. When testapp.exe runs in D:_websites\DocWebV2\ or D:_websites\DocWebV2\ LTMRender\ folder, it succeeds and filemon is showing D:_websites\DocWebV2\LTMRender\pinPDF.dll SUCCESS If I run my testapp.exe in the D:_websites\DocWebV2\Client – where my asp pages run, it shows D:_websites\DocWebV2\pinPDF.dll NAME NOT FOUND and then D:_websites\DocWebV2\pinPDF\pinPDF.dll FILE NOT FOUND I’m not sure why it is not looking in the correct folder if it’s under this particular folder only.

  • ASP.net dynamic controls issue when trying to reverse them

    - by Mattias Sandsäter
    I add some DropDownList dynamically to my form. It seems to work as it should when I use ...Controls.Add(dropdownlist), but in an attempt to turn them around and show them in reversed order I have tried to use ....Controls.AddAt(0, dropdownlist) However, this causes some strange behaviour. Before we dig in to the code, is there something I should know about dynamic adding, and more specific the AddAt()-method that usually causes trouble? Short description about what I do I start with a DropDownList (level1), when I choose something there, a new list should be added (level2) and so on. You can say you go your way down in a menu structure. Whenever you want you can change your choice at whatever level you want (of course not on later levels that you dont see yet). So lets say you are down to level 4 (You then have four boxes) and change your choice at level1, when the page reloads you are back to two boxes. http://forums.asp.net/p/885886/927411.aspx It seems that my problem was discussed here, but I didn´t see any solution about how I can acheive my intended behaviour.

  • Using java2d user space measurements with TextLayout and LineBreakMeasurer

    - by Andrew Wheeler
    I have a java2d image defined in user space (mm) to print an identity card. The transformation to pixels is by using an AffineTransform for the required DPI (Screen or print). I want to wrap text across several lines but the the TextLayout does not respect user space co-ordinates. private void drawParagraph(Graphics2D g2d, Rectangle2D area, String text) { LineBreakMeasurer lineMeasurer; AttributedString string = new AttributedString(text); AttributedCharacterIterator paragraph = string.getIterator(); int paragraphStart = paragraph.getBeginIndex(); int paragraphEnd = paragraph.getEndIndex(); FontRenderContext frc = g2d.getFontRenderContext(); lineMeasurer = new LineBreakMeasurer(paragraph, frc); float breakWidth = (float)area.getWidth(); float drawPosY = (float)area.getY(); float drawPosX = (float)area.getX(); lineMeasurer.setPosition(paragraphStart); while (lineMeasurer.getPosition() < paragraphEnd) { TextLayout layout = lineMeasurer.nextLayout(breakWidth); drawPosY += layout.getAscent(); layout.draw(g2d, drawPosX, drawPosY); drawPosY += layout.getDescent() + layout.getLeading(); } } The above code determines font metrics using user space sizing of the Font and thus turn out rather large. The font size is calculated as best vertical fit for the number of lines in an area with the calculation as below. E.g. attr.put(TextAttribute.SIZE, (geTextArea().getHeight() / noOfLines - LINE_SPACING) ); When using g2d.drawString("Some text to display", x, y); the font size appears correct. Does anyone have a better way of doing text layout in user space co-ords?

  • Where do you take mocking - immediate dependencies, or do you grow the boundaries...?

    - by Peter Mounce
    So, I'm reasonably new to both unit testing and mocking in C# and .NET; I'm using xUnit.net and Rhino Mocks respectively. I'm a convert, and I'm focussing on writing behaviour specifications, I guess, instead of being purely TDD. Bah, semantics; I want an automated safety net to work above, essentially. A thought struck me though. I get programming against interfaces, and the benefits as far as breaking apart dependencies goes there. Sold. However, in my behaviour verification suite (aka unit tests ;-) ), I'm asserting behaviour one interface at a time. As in, one implementation of an interface at a time, with all of its dependencies mocked out and expectations set up. The approach seems to be that if we verify that a class behaves as it should against its collaborating dependencies, and in turn relies on each of those collaborating dependencies to have signed that same quality contract, we're golden. Seems reasonable enough. Back to the thought, though. Is there any value in semi-integration tests, where a test-fixture is asserting against a unit of concrete implementations that are wired together, and we're testing its internal behaviour against mocked dependencies? I just re-read that and I think I could probably have worded it better. Obviously, there's going to be a certain amount of "well, if it adds value for you, keep doing it", I suppose - but has anyone else thought about doing that, and reaped benefits from it outweighing the costs?

  • objective C architecture question

    - by thekevinscott
    Hey folks, I'm currently teaching myself objective C. I've gone through the tutorials, but I find I learn best when slogging through a project of my own, so I've embarked on making a backgammon app. Now that I'm partway in, I'm realizing there's some overall architecture things I just don't understand. I've established a "player" class, a "piece" class, and a "board" class. A piece theoretically belongs to both a player and the board. For instance, a player has a color, and every turn makes a move; so the player owns his pieces. At the same time, when moving a piece, it has to check whether it's a valid move, whether there are pieces on the board, etc. From my reading it seems like it's frowned upon to reach across classes. For instance, when a player makes a move, where should the function live that moves the piece? Should it exist on board? This would be my instinct, as the board should decide whether a move is valid or not; but the piece needs to initialize that query, as its the one being moved, no? Any info to help a noob would be super appreciated. Thanks guys!

  • C# Inheritence: Choosing what repository based on type of inherited class

    - by Oskar Kjellin
    I have been making a program that downloads information about movies from the internet. I have a base class Title, which represents all titles. Movie, Serie and Episode are inherited from that class. To save them to the database I have 2 services, MovieService and SerieService. They in turn call repositories, but that is not important here. I have a method Save(Title title) which I am not very happy with. I check for what type the title is and then call the correct service. I would like to perhaps write like this: ITitleService service = title.GetService(); title.GetSavedBy(service); So I have an abstract method on Title that returns an ITitleSaver, which will return the correct service for the instance. My question is how should I implement ITitleSaver? If I make it accept Title I will have to cast it to the correct type before calling the correct overload. Which will lead to having to deal with casting once again. What is the best approach to dealing with this? I would like to have the saving logic in the corresponding class.

  • What is the best testing pattern for checking that parameters are being used properly?

    - by Joseph
    I'm using Rhino Mocks to try to verify that when I call a certain method, that the method in turn will properly group items and then call another method. Something like this: //Arrange var bucketsOfFun = new BucketGame(); var balls = new List<IBall> { new Ball { Color = Color.Red }, new Ball { Color = Color.Blue }, new Ball { Color = Color.Yellow }, new Ball { Color = Color.Orange }, new Ball { Color = Color.Orange } }; //Act bucketsOfFun.HaveFunWithBucketsAndBalls(balls); //Assert ??? Here is where the trouble begins for me. My method is doing something like this: public void HaveFunWithBucketsAndBalls(IList<IBall> balls) { //group all the balls together according to color var blueBalls = GetBlueBalls(balls); var redBalls = GetRedBalls(balls); // you get the idea HaveFunWithABucketOfBalls(blueBalls); HaveFunWithABucketOfBalls(redBalls); // etc etc with all the different colors } public void HaveFunWithABucketOfBalls(IList<IBall> colorSpecificBalls) { //doing some stuff here that i don't care about //for the test i'm writing right now } What I want to assert is that each time I call HaveFunWithABucketOfBalls that I'm calling it with a group of 1 red ball, then 1 blue ball, then 1 yellow ball, then 2 orange balls. If I can assert that behavior then I can verify that the method is doing what I want it to do, which is grouping the balls properly. Any ideas of what the best testing pattern for this would be?

  • Word VBA - Find text between delimiters and convert to lower case

    - by jJack
    I would like to find text which is between the < and characters, and then turn any found text into "normal" case, where first letter of word is capitalized. Here is what I have thus far: Function findTextBetweenCarots() As String Dim strText As String With Selection .Find.Text = "<" ' what about <[^0-9]+> ? .Find.Forward = True .Find.Wrap = wdFindContinue End With Selection.Find.Execute ' Application.Selection. ' how do I get the text between the other ">"? findCarotSymb = Application.Selection.Text End Function Or, is there a better way of doing this? I also approached the problem using the VBScript Regex 5.5 library, which worked on simple documents, but not on certain documents with complex tables. For example, trying to just bold the text (for simplicity): Sub BoldUpperCaseWords() Dim regEx, Match, Matches Dim rngRange As Range Set regEx = New RegExp regEx.Pattern = "<[^0-9]+>" regEx.IgnoreCase = False regEx.Global = True Set Matches = regEx.Execute(ActiveDocument.Range.Text) For Each Match In Matches ActiveDocument.Range(Match.FirstIndex, Match.FirstIndex + Len(Match.Value)).Bold = True Next End Sub would not work in a document with tables. In fact, it would not even bold the correct text (the text between the <. This leads me to believe I have a broader issue here that I am missing. Here is what a sample doc looks like. Notice the wrong text is bold:

  • How to find the leaky faucet that loads into Malloc 32kb

    - by Rob
    I have been messing around with Leaks trying to find which function is not being deallocated (I am still new to this) and could really use some experienced insight. I have this bit of code that seems to be the culprit. Every time I press the button that calls this code, 32kb of memory is additionally allocated to memory and when the button is released that memory does not get deallocated. What I found was that everytime that AVAudioPlayer is called to play an m4a file, the final function to parse the m4a file is MP4BoxParser::Initialize() and this in turn allocates 32kb of memory through Cached_DataSource::ReadBytes My question is, how do I go about deallocating that after it is finished so that it doesn't keep allocating 32kb every time the button is pressed? Any help you could provide is greatly appreciated! - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //stop playing theAudio.stop; // cancel any pending handleSingleTap messages [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSingleTap) object:nil]; UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [g_AppsList objectAtIndex: [touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource: filename ofType:@"m4a"]; theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:-1]; [theAudio setVolume: g_Volume]; [theAudio play]; }

  • Duplicate Items Using Join in NHibernate Map

    - by Colin Bowern
    I am trying to retrieve the individual detail rows without having to create an object for the parent. I have a map which joins a parent table with the detail to achieve this: Table("UdfTemplate"); Id(x => x.Id, "Template_Id"); Map(x => x.FieldCode, "Field_Code"); Map(x => x.ClientId, "Client_Id"); Join("UdfFields", join => { join.KeyColumn("Template_Id"); join.Map(x => x.Name, "COLUMN_NAME"); join.Map(x => x.Label, "DISPLAY_NAME"); join.Map(x => x.IsRequired, "MANDATORY_FLAG") .CustomType<YesNoType>(); join.Map(x => x.MaxLength, "DATA_LENGTH"); join.Map(x => x.Scale, "DATA_SCALE"); join.Map(x => x.Precision, "DATA_PRECISION"); join.Map(x => x.MinValue, "MIN_VALUE"); join.Map(x => x.MaxValue, "MAX_VALUE"); }); When I run the query in NH using: Session.CreateCriteria(typeof(UserDefinedField)) .Add(Restrictions.Eq("FieldCode", code)).List<UserDefinedField>(); I get back the first row three times as opposed to the three individual rows it should return. Looking at the SQL trace in NH Profiler the query appears to be correct. The problem feels like it is in the mapping but I am unsure how to troubleshoot that process. I am about to turn on logging to see what I can find but I thought I would post here in case someone with experience mapping joins knows where I am going wrong.

  • Architectural conundrum

    - by Dejan
    The worst thing when working on a one man project is the lack of input that you usually get from your coworkers. And because of the lack of that you tend to make obvious mistakes. After going down that road for some time I would need some help from the community. I started a little home-brew project that should turn into a portal of some sorts. And the main thing that is bothering me is the persistence layer that i have concocted. It should be completely separated from the presentation layer for starters and a OR mapper is also somewhere. This is because I have multiple data stores that have to be used. So the base idea was that the individual "repositories" operate each on their individual database and that the business layer then aggregates the business objects which are then transformed in the presentation layer into view objects. The main problem I face is the following: Multiple classes for the same concept - There is a DAL representation of a user and BL representation of user and a view representation of a user. I can handle the transformation with a tool but is this really the right way. I mean they are all nicely separated, but the overhead is quite something. What do you think? Am I going too deep into the separation of concern rabbit hole or is this still normal?

  • nedmalloc: where does mem<fm come from?

    - by Suma
    While implementing nedmalloc into my application, I am frequently hitting a situation when nedmalloc refuses to free a block of memory, claiming it did not allocate it. While debugging I have come up to the point I see a particular condition which is failing, all other (including magic numbers) succeed. The condition is this: if((size_t)mem-(size_t)fm>=(size_t)1<<(SIZE_T_BITSIZE-1)) return 0; On Win32 this seems to be equivalent to: if((int)((size_t)mem-(size_t)fm)<0) return 0; Which seems to be the same as: if((size_t)mem<(size_t)fm) return 0; In my case I really see mem < fm. What I do not understand now is, where does this condition come from. I cannot find anything which would guarantee the fm <= m anywhere in code. Yet, "select isn't broken": I doubt it would really be a bug in nedmalloc, most likely I am doing something wrong somewhere, but I cannot find it. Once I turn debugging features of nedmalloc on, the problem goes away. If someone here understands inner working of nedmalloc, could you please explain to me why is fm <= m?
