• How to reduce Entity Framework 4 query compile time?

  - by Rup

  Summary: We're having problems with EF4 query compilation times of 12+ seconds. Cached queries will only get us so far; are there any ways we can actually reduce the compilation time? Is there anything we might be doing wrong we can look for? Thanks! We have an EF4 model which is exposed over the WCF services. For each of our entity types we expose a method to fetch and return the whole entity for display / edit including a number of referenced child objects. For one particular entity we have to .Include() 31 tables / sub-tables to return all relevant data. Unfortunately this makes the EF query compilation prohibitively slow: it takes 12-15 seconds to compile and builds a 7,800-line, 300K query. This is the back-end of a web UI which will need to be snappier than that. Is there anything we can do to improve this? We can CompiledQuery.Compile this - that doesn't do any work until first use and so helps the second and subsequent executions but our customer is nervous that the first usage shouldn't be slow either. Similarly if the IIS app pool hosting the web service gets recycled we'll lose the cached plan, although we can increase lifetimes to minimise this. Also I can't see a way to precompile this ahead of time and / or to serialise out the EF compiled query cache (short of reflection tricks). The CompiledQuery object only contains a GUID reference into the cache so it's the cache we really care about. (Writing this out it occurs to me I can kick off something in the background from app_startup to execute all queries to get them compiled - is that safe?) However even if we do solve that problem, we build up our search queries dynamically with LINQ-to-Entities clauses based on which parameters we're searching on: I don't think the SQL generator does a good enough job that we can move all that logic into the SQL layer so I don't think we can pre-compile our search queries. This is less serious because the search data results use fewer tables and so it's only 3-4 seconds compile not 12-15 but the customer thinks that still won't really be acceptable to end-users. So we really need to reduce the query compilation time somehow. Any ideas? Profiling points to ELinqQueryState.GetExecutionPlan as the place to start and I have attempted to step into that but without the real .NET 4 source available I couldn't get very far, and the source generated by Reflector won't let me step into some functions or set breakpoints in them. The project was upgraded from .NET 3.5 so I have tried regenerating the EDMX from scratch in EF4 in case there was something wrong with it but that didn't help. I have tried the EFProf utility advertised here but it doesn't look like it would help with this. My large query crashes its data collector anyway. I have run the generated query through SQL performance tuning and it already has 100% index usage. I can't see anything wrong with the database that would cause the query generator problems. Is there something O(n^2) in the execution plan compiler - is breaking this down into blocks of separate data loads rather than all 32 tables at once likely to help? Setting EF to lazy-load didn't help. I've bought the pre-release O'Reilly Julie Lerman EF4 book but I can't find anything in there to help beyond 'compile your queries'. I don't understand why it's taking 12-15 seconds to generate a single select across 32 tables so I'm optimistic there's some scope for improvement! Thanks for any suggestions! We're running against SQL Server 2008 in case that matters and XP / 7 / server 2008 R2 using RTM VS2010.

• Writing more efficient xquery code (avoiding redundant iteration)

  - by Coquelicot

  Here's a simplified version of a problem I'm working on: I have a bunch of xml data that encodes information about people. Each person is uniquely identified by an 'id' attribute, but they may go by many names. For example, in one document, I might find <person id=1>Paul Mcartney</person> <person id=2>Ringo Starr</person> And in another I might find: <person id=1>Sir Paul McCartney</person> <person id=2>Richard Starkey</person> I want to use xquery to produce a new document that lists every name associated with a given id. i.e.: <person id=1> <name>Paul McCartney</name> <name>Sir Paul McCartney</name> <name>James Paul McCartney</name> </person> <person id=2> ... </person> The way I'm doing this now in xquery is something like this (pseudocode-esque): let $ids := distinct-terms( [all the id attributes on people] ) for $id in $ids return <person id={$id}> { for $unique-name in distinct-values ( for $name in ( [all names] ) where $name/@id=$id return $name ) return <name>{$unique-name}</name> } </person> The problem is that this is really slow. I imagine the bottleneck is the innermost loop, which executes once for every id (of which there are about 1200). I'm dealing with a fair bit of data (300 MB, spread over about 800 xml files), so even a single execution of the query in the inner loop takes about 12 seconds, which means that repeating it 1200 times will take about 4 hours (which might be optimistic - the process has been running for 3 hours so far). Not only is it slow, it's using a whole lot of virtual memory. I'm using Saxon, and I had to set java's maximum heap size to 10 GB (!) to avoid getting out of memory errors, and it's currently using 6 GB of physical memory. So here's how I'd really like to do this (in Pythonic pseudocode): persons = {} for id in ids: person[id] = set() for person in all_the_people_in_my_xml_document: persons[person.id].add(person.name) There, I just did it in linear time, with only one sweep of the xml document. Now, is there some way to do something similar in xquery? Surely if I can imagine it, a reasonable programming language should be able to do it (he said quixotically). The problem, I suppose, is that unlike Python, xquery doesn't (as far as I know) have anything like an associative array. Is there some clever way around this? Failing that, is there something better than xquery that I might use to accomplish my goal? Because really, the computational resources I'm throwing at this relatively simple problem are kind of ridiculous.

• Pipe overwrites buffer, don't know how to overcome

  - by Kalec

  I use a simple pipe. I read with a while, 1 char at a time, I think every time I read a char I overwrite something #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <sys/wait.h> #include <string.h> int main () { int pipefd[2]; int cpid; char buf[31]; if (pipe(pipefd) == -1) { perror("pipe"); exit(EXIT_FAILURE) } cpid = fork(); if (cpid == -1) P perror("cpid"); exit(EXIT_FAILURE); } if (cpid == 0) { // child reads from pipe close (pipefd[1]); // close unused write end while (read (pipefd[0], &buf, 1)>0); printf ("Server receives: %s", buf); close (pipefd[0])l exit (EXIT_SUCCESS); } else { // parent writes to pipe close (pipefd[0]); // closing unused read end; char buf2[30]; printf("Server transmits: "); scanf ("%s", buf2); write (pipefd[1], buf2, strlen(buf2)+1); close(pipefd[1]); wait(NULL); exit(EXIT_SUCCESS); } return 0; } For example, if I input: "Flowers" it prints F and then ~6 unprintable characters

• setTimeout in javascript not giving browser 'breathing room'

  - by C Bauer

  Alright, I thought I had this whole setTimeout thing perfect but I seem to be horribly mistaken. I'm using excanvas and javascript to draw a map of my home state, however the drawing procedure chokes the browser. Right now I'm forced to pander to IE6 because I'm in a big organisation, which is probably a large part of the slowness. So what I thought I'd do is build a procedure called distributedDrawPolys (I'm probably using the wrong word there, so don't focus on the word distributed) which basically pops the polygons off of a global array in order to draw 50 of them at a time. This is the method that pushes the polygons on to the global array and runs the setTimeout: for (var x = 0; x < polygon.length; x++) { coordsObject.push(polygon[x]); fifty++; if (fifty > 49) { timeOutID = setTimeout(distributedDrawPolys, 5000); fifty = 0; } } I put an alert at the end of that method, it runs in practically a second. The distributed method looks like: function distributedDrawPolys() { if (coordsObject.length > 0) { for (x = 0; x < 50; x++) { //Only do 50 polygons var polygon = coordsObject.pop(); var coordinate = polygon.selectNodes("Coordinates/point"); var zip = polygon.selectNodes("ZipCode"); var rating = polygon.selectNodes("Score"); if (zip[0].text.indexOf("HH") == -1) { var lastOriginCoord = []; for (var y = 0; y < coordinate.length; y++) { var point = coordinate[y]; latitude = shiftLat(point.getAttribute("lat")); longitude = shiftLong(point.getAttribute("long")); if (y == 0) { lastOriginCoord[0] = point.getAttribute("long"); lastOriginCoord[1] = point.getAttribute("lat"); } if (y == 1) { beginPoly(longitude, latitude); } if (y > 0) { if (translateLongToX(longitude) > 0 && translateLongToX(longitude) < 800 && translateLatToY(latitude) > 0 && translateLatToY(latitude) < 600) { drawPolyPoint(longitude, latitude); } } } y = 0; if (zip[0].text != targetZipCode) { if (rating[0] != null) { if (rating[0].text == "Excellent") { endPoly("rgb(0,153,0)"); } else if (rating[0].text == "Good") { endPoly("rgb(153,204,102)"); } else if (rating[0].text == "Average") { endPoly("rgb(255,255,153)"); } } else { endPoly("rgb(255,255,255)"); } } else { endPoly("rgb(255,0,0)"); } } } } Ugh I don't know if that is properly formatted, I ended up with an extra bracket < So I thought the setTimeout method would allow the site to draw the polygons in groups so the users would be able to interact with the page while it was still drawing. What am I doing wrong here?

• MouseMotionListener inside JTable

  - by Harish

  I am trying to add MouseMotion event to the label and move it based on the dragging of the mouse and make it move along with my mouse.However the mousemotion is very difficult to control making this action not usable.

• Multidimensional array problem in VHDL?

  - by Nektarios

  I'm trying to use a multidimensional array in VHDL and I'm having a lot of trouble getting it to work properly. My issue is that I've got an array of 17, of 16 vectors, of a given size. What I want to do is create 17 registers that are array of 16 * std_logic_vector of 32 bits (which = my b, 512). So, I'm trying to pass in something to input and output on the register instantiation that tells the compiler/synthesizer that I want to pass in something that is 512 bits worth... Similar to in C if I had: int var[COLS][ROWS][ELEMENTS]; memcpy(&var[3].. // I'm talking about 3rd COL here, passing in memory that is ROWS*ELEMENTS long (My actual declaration is here:) type partial_pipeline_registers_type is array (0 to 16, 0 to 15) of std_logic_vector(iw - 1 downto 0); signal h_blk_pipelined_input : partial_pipeline_registers_type; I tried simply using h_blk_pipelined_input(0) .. up to (16) but this doesn't work. I get the following error, which makes me see that I need to double index in to the array: ERROR:HDLParsers:821 - (at the register) Wrong index type for h_blk_pipelined_input. So then I tried what's below, and I get this error: ERROR:HDLParsers:164 - (at the register code). parse error, unexpected TO, expecting COMMA or CLOSEPAR instantiate_h_pipelined_reg : regn generic map ( N=> b, init => bzeros ) port map ( clk => clk , rst => '0', en => '1', input => h_blk_pipelined_input((i - 1), 0 to 15), output=> h_blk_pipelined_input((i), 0 to 15)); -- Changing 0 to 15 to (0 to 15) has no effect... I'm using XST, and from their documentation (http://www.xilinx.com/itp/xilinx6/books/data/docs/xst/xst0067_9.html), the above should have worked: ...declaration: subtype MATRIX15 is array(4 downto 0, 2 downto 0) of STD_LOGIC_VECTOR (7 downto 0); A multi-dimensional array signal or variable can be completely used: Just a slice of one row can be specified: MATRIX15 (4,4 downto 1) <= TAB_B (3 downto 0); One alternative is that I can create more registers that are 16 times smaller, and instead of trying to do all '0 to 15' at once, I would just do that 15 additional times. However, I think this may lead to inefficiency in synthesis and I don't feel like this is the right solution. EDIT: Tried what Ben said, instantiate_h_m_qa_pipeline_registers: for i in 1 to 16 generate instantiate_h_pipelined_reg : regn generic map ( N=> b, init => bzeros ) port map ( clk => clk , rst => '0', en => '1', input => h_blk_pipelined_input(i - 1), output=> h_blk_pipelined_input(i)); end generate instantiate_h_m_qa_pipeline_registers; The signals are now defined as: type std_logic_block is array (0 to 15) of std_logic_vector(iw - 1 downto 0) ; type partial_pipeline_registers_type is array (0 to 16) of std_logic_block; signal h_blk_pipelined_input : partial_pipeline_registers_type; And the error I get from XST is: ERROR:HDLParsers:800 - ((where the register part is)) Type of input is incompatible with type of h_blk_pipelined_input. I'm able to do everything I was able to do before, using ()() syntax instead of ( , ) so I haven't lost anything going this way, but it still doesn't resolve my problem.

• .NET Programmatically invoke screenclick doesn't work?

  - by ropstah

  I'm trying to programmatically invoke an onclick event however the click is not received/handled. Am I missing something, or is security preventing the click to be executed? I have a forms application which is invisible. Basically I would like to say: DoDoubleClick(wait, x, y) This should raise two click (mousedown+mouseup) events on screen with the specified wait interval. However the click isn't received in a Flash application in Firefox (which is running at that moment). Here's my code: Form: Public Class Form1 Private WithEvents gmh As GlobalMouseHook Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load gmh = New GlobalMouseHook() Me.Visible = false gmh.DoDoubleClick(50, 800, 600) End Sub Private Sub Form1_FormClosed(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles MyBase.FormClosed gmh.Dispose() End Sub Private Sub gmh_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles gmh.MouseDown End Sub Private Sub gmh_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles gmh.MouseMove End Sub Private Sub gmh_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles gmh.MouseUp End Sub End Class GlobalMouseHook class: Friend Class GlobalMouseHook Implements IDisposable Private hhk As IntPtr = IntPtr.Zero Private disposedValue As Boolean = False Public Event MouseDown As MouseEventHandler Public Event MouseUp As MouseEventHandler Public Event MouseMove As MouseEventHandler Public Sub New() Hook() End Sub Private Sub Hook() Dim hInstance As IntPtr = LoadLibrary("User32") hhk = SetWindowsHookEx(WH_MOUSE_LL, AddressOf Me.HookProc, hInstance, 0) End Sub Private Sub Unhook() UnhookWindowsHookEx(hhk) End Sub Public Sub DoDoubleClick(ByVal wait As Integer, ByVal x As Integer, ByVal y As Integer) RaiseEvent MouseDown(Me, New MouseEventArgs(MouseButtons.Left, 1, x, y, 0)) RaiseEvent MouseUp(Me, Nothing) System.Threading.Thread.Sleep(wait) RaiseEvent MouseDown(Me, New MouseEventArgs(MouseButtons.Left, 1, x, y, 0)) RaiseEvent MouseUp(Me, Nothing) End Sub Private Function HookProc(ByVal nCode As Integer, ByVal wParam As UInteger, ByRef lParam As MSLLHOOKSTRUCT) As Integer If nCode >= 0 Then Select Case wParam Case WM_LBUTTONDOWN RaiseEvent MouseDown(Me, New MouseEventArgs(MouseButtons.Left, 0, lParam.pt.x, lParam.pt.y, 0)) Case WM_RBUTTONDOWN RaiseEvent MouseDown(Me, New MouseEventArgs(MouseButtons.Right, 0, lParam.pt.x, lParam.pt.y, 0)) Case WM_MBUTTONDOWN RaiseEvent MouseDown(Me, New MouseEventArgs(MouseButtons.Middle, 0, lParam.pt.x, lParam.pt.y, 0)) Case WM_LBUTTONUP, WM_RBUTTONUP, WM_MBUTTONUP RaiseEvent MouseUp(Nothing, Nothing) Case WM_MOUSEMOVE RaiseEvent MouseMove(Nothing, Nothing) Case WM_MOUSEWHEEL, WM_MOUSEHWHEEL Case Else Console.WriteLine(wParam) End Select End If Return CallNextHookEx(hhk, nCode, wParam, lParam) End Function Private Structure API_POINT Public x As Integer Public y As Integer End Structure Private Structure MSLLHOOKSTRUCT Public pt As API_POINT Public mouseData As UInteger Public flags As UInteger Public time As UInteger Public dwExtraInfo As IntPtr End Structure Private Const WM_MOUSEWHEEL As UInteger = &H20A Private Const WM_MOUSEHWHEEL As UInteger = &H20E Private Const WM_MOUSEMOVE As UInteger = &H200 Private Const WM_LBUTTONDOWN As UInteger = &H201 Private Const WM_LBUTTONUP As UInteger = &H202 Private Const WM_MBUTTONDOWN As UInteger = &H207 Private Const WM_MBUTTONUP As UInteger = &H208 Private Const WM_RBUTTONDOWN As UInteger = &H204 Private Const WM_RBUTTONUP As UInteger = &H205 Private Const WH_MOUSE_LL As Integer = 14 Private Delegate Function LowLevelMouseHookProc(ByVal nCode As Integer, ByVal wParam As UInteger, ByRef lParam As MSLLHOOKSTRUCT) As Integer Private Declare Auto Function LoadLibrary Lib "kernel32" (ByVal lpFileName As String) As IntPtr Private Declare Auto Function SetWindowsHookEx Lib "user32.dll" (ByVal idHook As Integer, ByVal lpfn As LowLevelMouseHookProc, ByVal hInstance As IntPtr, ByVal dwThreadId As UInteger) As IntPtr Private Declare Function CallNextHookEx Lib "user32" (ByVal hhk As IntPtr, ByVal nCode As Integer, ByVal wParam As UInteger, ByRef lParam As MSLLHOOKSTRUCT) As Integer Private Declare Function UnhookWindowsHookEx Lib "user32" (ByVal hhk As IntPtr) As Boolean ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects).

• I'm looking for this graph solution

  - by Ben Fransen

  Hello all, Recently I found a pretty graph when I was browsing the adminskins at ThemeForest and in one of the templates I found a really nice, smooth, clean graph. But I've searching arround but so far without luck finding out which solution is used. And example can be found at: http://enstyled.com/adminus/original/page.html The source of this graph looks like: <table class="stats bar" cellpadding="0" cellspacing="0" width="100%"> <thead> <tr> <td>&nbsp;</td> <th scope="col">02.09</th> <th scope="col">03.09</th> <th scope="col">04.09</th> <th scope="col">05.09</th> <th scope="col">06.09</th> <th scope="col">07.09</th> <th scope="col">08.09</th> <th scope="col">09.09</th> <th scope="col">10.09</th> <th scope="col">11.09</th> <th scope="col">12.09</th> <th scope="col">01.10</th> <th scope="col">02.10</th> <th scope="col">03.10</th> </tr> </thead> <tbody> <tr> <th scope="row">Page views</th> <td>1800</td> <td>900</td> <td>700</td> <td>1200</td> <td>600</td> <td>2800</td> <td>3200</td> <td>500</td> <td>2200</td> <td>1000</td> <td>1200</td> <td>700</td> <td>650</td> <td>800</td> </tr> <tr> <th scope="row">Unique visitors</th> <td>1600</td> <td>650</td> <td>550</td> <td>900</td> <td>500</td> <td>2300</td> <td>2700</td> <td>350</td> <td>1700</td> <td>600</td> <td>1000</td> <td>500</td> <td>400</td> <td>700</td> </tr> </tbody> </table> Can someone please tell me which graphingsolution is used here? Thanks in advance, Ben Fransen

  <select name="mySelectboxsituation_found" id="mySelectboxsituation_found"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> < a href="#" class="incidenttype" name="all" onClick="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"/>CLICK HERE < / a> function cleanUp(){ var subsituation_found1 = $("#fancybox- frame").contents().find('input:radio[name=incident_subcate]:checked').val(); } $(".incidenttype").fancybox({ 'width' : 900, 'height' : 600, 'autoScale': false, 'transitionIn': 'none', 'transitionOut': 'none', 'type': 'iframe', 'onCleanup': cleanUp ); }); clicking on "CLICK HERE" opens the fancybox and transfers the value selected in the drop down box. What I would like to do is open the fancy box when i change the value in the dropdown box...without having to click on the click here link.....i know it is posisble using something like _this....but i am not sure and am looking for some direction... ideally some thing like this ... <select name="mySelectboxsituation_found" id="mySelectboxsituation_found" onChange="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> does any have an idea how to do it....

• Custom Geo Tagging. Name to position and position to name

  - by Toni Michel Caubet

  Hello there i am implementing a custom geo tagging system, ok Array where i store the cordenades of each place /* ******Opciones del etiquetado del mapa*** */ var TagSpeed = 800; //el tiempo de la animacion var animate = true; //false = fadeIn / true = animate var paises = { "isora": { leftX: '275', topY: '60', name: 'Gran Melia Palacio de Isora' }, "pepe": { leftX: '275', topY: '60', name: 'Gran Melia de Don Pepe' }, "australia": { leftX: '565', topY: '220', name: 'Gran Melia Uluru' }, "otro": { // ejemplo leftX: '565', // cordenada x topY: '220', // cordenada y name: 'soy otro' // nombre a mostrar } /* <==> <span class="otro mPointer">isora</span> */ } /**/ this is how i check with js function escucharMapa(){ /*fOpciones*/ $('.mPointer').bind('mouseover',function(){ var clase = $(this).attr('class').replace(" mPointer", ""); var left_ = paises[clase].leftX; var top_ = paises[clase].topY; var name_ = paises[clase].name; $('.arrow .text').html(name_); /*Esta linea centra la etiqueta del hotel con la flecha.

• Multiple data series in real time plot

  - by Gr3n

  Hi, I'm kind of new to Python and trying to create a plotting app for values read via RS232 from a sensor. I've managed (after some reading and copying examples online) to get a plot working that updates on a timer which is great.

• Get rid of jfreechart chartpanel unnecessary space

  - by ryvantage

  I am trying to get a JFreeChart ChartPanel to remove unwanted extra space between the edge of the panel and the graph itself. To best illustrate, here's a SSCCE (with JFreeChart installed): public static void main(String[] args) { JPanel panel = new JPanel(new GridBagLayout()); GridBagConstraints gbc = new GridBagConstraints(); gbc.fill = GridBagConstraints.BOTH; gbc.gridwidth = 1; gbc.gridheight = 1; gbc.weightx = 1; gbc.weighty = 1; gbc.gridy = 1; gbc.gridx = 1; panel.add(createChart("Sales", Chart_Type.DOLLARS, 100000, 115000), gbc); gbc.gridx = 2; panel.add(createChart("Quotes", Chart_Type.DOLLARS, 250000, 240000), gbc); gbc.gridx = 3; panel.add(createChart("Profits", Chart_Type.PERCENTAGE, 40.00, 38.00), gbc); JFrame frame = new JFrame(); frame.add(panel); frame.setSize(800, 300); frame.setLocationRelativeTo(null); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } private static ChartPanel createChart(String title, Chart_Type type, double goal, double actual) { double maxValue = goal * 2; double yellowToGreenNum = goal; double redToYellowNum = goal * .75; DefaultValueDataset dataset = new DefaultValueDataset(actual); JFreeChart jfreechart = createChart(dataset, Math.max(actual, maxValue), redToYellowNum, yellowToGreenNum, title, type); ChartPanel chartPanel = new ChartPanel(jfreechart); chartPanel.setBorder(new LineBorder(Color.red)); return chartPanel; } private static JFreeChart createChart(ValueDataset valuedataset, Number maxValue, Number redToYellowNum, Number yellowToGreenNum, String title, Chart_Type type) { MeterPlot meterplot = new MeterPlot(valuedataset); meterplot.setRange(new Range(0.0D, maxValue.doubleValue())); meterplot.addInterval(new MeterInterval(" Goal Not Met ", new Range(0.0D, redToYellowNum.doubleValue()), Color.lightGray, new BasicStroke(2.0F), new Color(255, 0, 0, 128))); meterplot.addInterval(new MeterInterval(" Goal Almost Met ", new Range(redToYellowNum.doubleValue(), yellowToGreenNum.doubleValue()), Color.lightGray, new BasicStroke(2.0F), new Color(255, 255, 0, 64))); meterplot.addInterval(new MeterInterval(" Goal Met ", new Range(yellowToGreenNum.doubleValue(), maxValue.doubleValue()), Color.lightGray, new BasicStroke(2.0F), new Color(0, 255, 0, 64))); meterplot.setNeedlePaint(Color.darkGray); meterplot.setDialBackgroundPaint(Color.white); meterplot.setDialOutlinePaint(Color.gray); meterplot.setDialShape(DialShape.CHORD); meterplot.setMeterAngle(260); meterplot.setTickLabelsVisible(false); meterplot.setTickSize(maxValue.doubleValue() / 20); meterplot.setTickPaint(Color.lightGray); meterplot.setValuePaint(Color.black); meterplot.setValueFont(new Font("Dialog", Font.BOLD, 0)); meterplot.setUnits(""); if(type == Chart_Type.DOLLARS) meterplot.setTickLabelFormat(NumberFormat.getCurrencyInstance()); else if(type == Chart_Type.PERCENTAGE) meterplot.setTickLabelFormat(NumberFormat.getPercentInstance()); JFreeChart jfreechart = new JFreeChart(title, JFreeChart.DEFAULT_TITLE_FONT, meterplot, false); return jfreechart; } enum Chart_Type { DOLLARS, PERCENTAGE } If you resize the frame, you can see that you cannot make the edge of the graph go to the edge of the panel (the panels are outlined in red). Especially on the bottom - there is always a gap between the bottom the graph and the bottom of the panel. Is there a way to make the graph fill the entire area? Is there a way to at least guarantee that it is touching one edge of the panel (i.e., it is touching the top and bottom or the left and right) ??

• Problem with large number of markers on the map...

  - by bobetko

  I am working on an Android app that already exists on iPhone. In the app, there is a Map activity that has (I counted) around 800 markers in four groups marked by drawable in four different colors. Each group can be turned on or off. Information about markers I have inside List. I create a mapOverlay for each group, then I attach that overlay to the map. I strongly believe that coding part I did properly. But I will attach my code anyway... The thing is, my Nexus One can't handle map with all those markers. It takes around 15 seconds just to draw 500 markers. Then when all drawn, map is not quite smooth. It is sort of hard to zoom and navigate around. It can be done, but experience is bad and I would like to see if something can be done there. iPhone seems doesn't have problems showing all these markers. It takes roughly about 1-2 seconds to show all of them and zooming and panning is not that bad. Slow down is noticeable but still acceptable. I personally think it is no good to draw all those markers, but app is designed by somebody else and I am not supposed to make any drastic changes. I am not sure what to do here. It seems I will have to come up with different functionality, maybe use GPS location, if known, and draw only markers within some radius, or, if location not known, use center of the screen(map) and draw markers around that. I will have to have reasonable explanation for my bosses in case I make these changes. I appreciate if anybody has any idas. And the code: ... for (int m = 0; m < ArrList.size(); m++) { tName = ArrList.get(m).get("name").toString(); tId = ArrList.get(m).get("id").toString(); tLat = ArrList.get(m).get("lat").toString();; tLng = ArrList.get(m).get("lng").toString();; try { lat = Double.parseDouble(tLat); lng = Double.parseDouble(tLng); p1 = new GeoPoint( (int) (lat * 1E6), (int) (lng * 1E6)); OverlayItem overlayitem = new OverlayItem(p1, tName, tId); itemizedoverlay.addOverlay(overlayitem); } catch (NumberFormatException e) { Log.d(TAG, "NumberFormatException" + e); } } mapOverlays.add(itemizedoverlay); mapView.postInvalidate(); ................................ public class HelloItemizedOverlay extends ItemizedOverlay<OverlayItem> { private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); private Context mContext; public HelloItemizedOverlay(Drawable defaultMarker, Context context) { super(boundCenterBottom(defaultMarker)); mContext = context; } public void addOverlay(OverlayItem overlay) { mOverlays.add(overlay); populate(); } @Override protected OverlayItem createItem(int i) { return mOverlays.get(i); } @Override public int size() { return mOverlays.size(); } @Override protected boolean onTap(int index) { final OverlayItem item = mOverlays.get(index); ... EACH MARKER WILL HAVE ONCLICK EVENT THAT WILL PRODUCE CLICABLE ... BALOON WITH MARKER'S NAME. return true; } }

• How to make a character jump, both on objects and just normal jump.

  - by haxerflaxer

  Hi, I'm kind of a beginner when it comes to java programming, and I have a project in school where I'm going to create a game much like Icy Tower. And my question is, how am I going to write to make the character stand on the ground and be able to jump up on objects? Here's my code so far: Part one package Sprites; import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; public class jumper { private String jump = "oka.png"; private int dx; private int dy; private int x; private int y; private Image image; public jumper() { ImageIcon ii = new ImageIcon(this.getClass().getResource(jump)); image = ii.getImage(); x = 50; y = 100; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = -5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oki.png")); image = ii.getImage(); } if (key == KeyEvent.VK_RIGHT){ dx = 5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oka.png")); image = ii.getImage(); } if (key == KeyEvent.VK_SPACE) { dy = -5; } if (key == KeyEvent.VK_DOWN) { dy = 5; } } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT){ dx = 0; } if (key == KeyEvent.VK_SPACE) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } Part two package Sprites; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.JPanel; import javax.swing.Timer; public class board extends JPanel implements ActionListener { private Timer klocka; private jumper jumper; public board() { addKeyListener(new TAdapter()); setFocusable(true); setBackground(Color.WHITE); setDoubleBuffered(true); jumper = new jumper(); klocka = new Timer(5, this); klocka.start(); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D)g; g2d.drawImage(jumper.getImage(), jumper.getX(), jumper.getY(), this); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public void actionPerformed(ActionEvent e) { jumper.move(); repaint(); } private class TAdapter extends KeyAdapter { public void keyReleased(KeyEvent e) { jumper.keyReleased(e); } public void keyPressed(KeyEvent e) { jumper.keyPressed(e); } } } Part three package Sprites; import javax.swing.JFrame; public class RType extends JFrame { public RType() { add(new board()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(800, 600); setLocationRelativeTo(null); setTitle("R - type"); setResizable(false); setVisible(true); } public static void main(String[] args) { new RType(); } } I really appreciate all the help I can get!

• Quickly or concisely determine the longest string per column in a row-based data collection

  - by ccornet

  Judging from the failure of my last inquiry, I need to calculate and preset the widths of a set of columns in a table that is being made into an Excel file. Unfortunately, the string data is stored in a row-based format, but the widths must be calculated in a column-based format. The data for the spreadsheets are generated from the following two collections: var dictFiles = l.Items.Cast<SPListItem>().GroupBy(foo => foo.GetSafeSPValue("Category")).ToDictionary(bar => bar.Key); StringDictionary dictCols = GetColumnsForItem(l.Title); Where l is an SPList whose title determines which columns are used. Each SPListItem corresponds to a row of data, which are sorted into separate worksheets based on Category (hence the dictionary). The second line is just a simple StringDictionary that has the column name (A, B, C, etc.) as a key and the corresponding SPListItme field display name as the corresponding value. So for each Category, I enumerate through dictFiles[somekey] to get all the rows in that sheet, and get the particular cell data using SPListItem.Fields[dictCols[colName]]. What I am asking is, is there a quick or concise method, for any one dictFiles[somekey], to retrieve a readout of the longest string in each column provided by dictCols? If it is impossible to get both quickness and conciseness, I can settle for either (since I always have the O(n*m) route of just enumerating the collection and updating an array whenever strCurrent.Length strLongest.Length). For example, if the goal table was the following... Item# Field1 Field2 Field3 1 Oarfish Atmosphere Pretty 2 Raven Radiation Adorable 3 Sunflower Flowers Cute I'd like a function which could cleanly take the collection of items 1, 2, and 3 and output in the correct order... Sunflower, Atmosphere, Adorable Using .NET 3.5 and C# 3.0.

• setting something disposed or invisible java

  - by OVERTONE

  this might be simple enough as just inserting the right method but i cant seem to get it right. i have a simple program with two buttons. each one changes the picture above them. but anytime i click the buttons i get some odd awt event queue error. i think its because im trying to add something to a frame after its already been made. package icnon; import javax.imageio.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class FrameIconExample extends JFrame implements ActionListener { JLabel j; JPanel p, l, k; JButton picOne, picTwo; Container cPane; public FrameIconExample() { JButton picOne = new JButton("picOne"); JButton picTwo = new JButton("picTwo"); picOne.setName("picOne"); picTwo.setName("picTwo"); picOne.addActionListener(this); picTwo.addActionListener(this); JPanel p = new JPanel(new GridLayout(2, 1)); JPanel l = new JPanel(new FlowLayout()); JPanel k = new JPanel(new FlowLayout()); cPane = getContentPane(); j = new JLabel(new ImageIcon("../meet/src/images/beautiful-closeup-portrait-photography.jpg")); l.add(j); k.add(picOne); k.add(picTwo); p.add(l); p.add(k); add(p); } public static void main(String[] args) { FrameIconExample frame = new FrameIconExample(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(new Dimension(300, 800)); frame.setTitle("Frame Icon Example"); // Display the form frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { JButton temp = (JButton) e.getSource(); String src = "../meet/src/images/Majken Kruse portrait - john.jpg"; //System.out.println(src + " " + temp.getName()); if(temp.getName().equalsIgnoreCase("picOne")) { src = "../meet/src/images/beautiful-closeup-portrait-photography.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("1"); } if(temp.getName().equalsIgnoreCase("picTwo")) { src = "../icontest/images/Majken Kruse portrait - john.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("2"); } } } its all just the one program so if you copy paste it into an editor you can see the stack trace. but the source of the image files wont be there. does anyone know how id do it? or where im goin wrong? stack trace: ../meet/src/images/beautiful-closeup-portrait-photography.jpg picOne Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at icnon.FrameIconExample.actionPerformed(FrameIconExample.java:68) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

• output image is not displayed

  - by gerry chocolatos

  so, im doing an image detection which i have to process on each red, green, n blue element to get the edge map and combine them become one to show the output. but it doesnt show my output image would anyone pls be kind enough to help me? here is my code so far. //get the red element process_red = new int[width * height]; counter = 0; for(int i = 0; i < 256; i++) { for(int j = 0; j < 256; j++) { int clr = buff_red.getRGB(j, i); int red = (clr & 0x00ff0000) >> 16; red = (0xFF<<24)|(red<<16)|(red<<8)|red; process_red[counter] = red; counter++; } } //set threshold value for red element int threshold = 100; for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { int bin = (buff_red.getRGB(x, y) & 0x000000ff); if (bin < threshold) bin = 0; else bin = 255; buff_red.setRGB(x,y, 0xff000000 | bin << 16 | bin << 8 | bin); } } and i do the same way for my green n blue elements. and then i wanted to get to combination of the three by doing it this way: //combine the three elements process_combine = new int[width * height]; counter = 0; for(int i = 0; i < 256; i++) { for(int j = 0; j < 256; j++) { int clr_a = buff_red.getRGB(j, i); int ar = clr_a & 0x000000ff; int clr_b = buff_green.getRGB(j, i); int bg = clr_b & 0x000000ff; int clr_c = buff_blue.getRGB(j, i); int cb = clr_b & 0x000000ff; int alpha = 0xff000000; int combine = alpha|(ar<<16)|(bg<<8)|cb; process_combine[counter] = combine; counter++; } } buff_rgb = new BufferedImage(width,height, BufferedImage.TYPE_INT_ARGB); Graphics rgb; rgb = buff_rgb.getGraphics(); rgb.drawImage(output_rgb, 0, 0, null); rgb.dispose(); repaint(); and to show the output whic is from the combining process, i use a draw method: g.drawImage(buff_rgb,800,100,this); but still it doesnt show the image. can anyone pls help me? ur help is really appreciated. thanks.

• Load image blurred Android

  - by Mira

  I'm trying to create a map for a game through an image, where each black pixel is equivalent to a wall, and yellow to flowers(1) and green grass(0) so far i had this image (50x50): http://i.imgur.com/Ydj9Cp2.png the problem here seems to be that, when i read the image on my code, it get's scaled up to 100x100, even tough i have it on the raw folder. I can't let it scale up or down because that will put noise and blur on the image and then the map won't be readable. here i have my code: (...) Bitmap tab=BitmapFactory.decodeResource(resources, com.example.lolitos2.R.raw.mappixel); //tab=Bitmap.createScaledBitmap(tab, 50, 50, false); Log.e("w", tab.getWidth()+"."+tab.getHeight()); for (int i = 0; i < tab.getWidth(); i++) { for (int j = 0; j < tab.getHeight(); j++) { int x = j; int y = i; switch (tab.getPixel(x, y)) { // se o é uma parede case Color.BLACK: getParedes()[x][y] = new Parede(x, y); break; case Color.GREEN: fundo.add(new Passivo(x,y,0)); break; default: fundo.add(new Passivo(x,y,1)); } } } How can i read my image Map without rescaling it?
