  • Dynamic programming: Find largest diamond (rhombus)

    - by Darksody
    I have a small program to do in Java. I have a 2D array filled with 0 and 1, and I must find the largest rhombus (as in square rotated by 90 degrees) and their numbers. Example: 0 1 0 0 0 1 1 0 1 1 1 0 1 0 1 1 1 1 0 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 Result: 1 1 1 1 1 1 1 1 1 1 1 1 1 The problem is similar to this SO question. If you have any idea, post it here.

  • Select part of a text that exists already in an above cell

    - by pragadheesh
    How do I get Excel to partially auto-complete a word using another that already exist in the same worksheet? Let's say I have the word "Microsoft" in a cell and in the cell below I want to type the word "Microhard". When I start typing Microhard, the word Microsoft appears shaded in black. How can I select the "Micro" part alone from Microsoft and continue to fill out the rest with "hard" without it trying to fill out as Microsoft?

  • jQuery.post dynamic data callback function

    - by FFish
    I have a script that requires quite e few seconds of processing, up to about minute. The script resizes an array of images, sharpens them and finally zips them up for the user to download. Now I need some sort of progress messages. I was thinking that with jQuery's .post() method the data from the callback function would progressively update, but that doesn't seem to work. In my example I am just using a loop to simulate my script: $(document).ready(function() { $('a.loop').click(function() { $.post('loop.php', {foo:"bar"}, function(data) { $("div").html(data); }); return false; }); }); loop.php: for ($i = 0; $i <= 100; $i++) { echo $i . "<br />"; } echo "done";

  • MS SQL replace sequence of same characters inside Text Field (TSQL only)

    - by zmische
    I have a text column varchar(4000) with text: 'aaabbaaacbaaaccc' and I need to remove all duplicated chars - so only one from sequence left: 'abacbac' It should not be a function, Procedure or CLR - Regex solution. Only true SQL select. Currently I think about using recursive WITH clause with replace 'aa'-'a', 'bb'-'b', 'cc'-'c'. So recursion should cycle until all duplicated sequences of that chars would be replaced. DO you have another solution, perhaps more Permormant one? PS: I searched through this site about different replace examples - they didnt suit to this case.

  • Jquery - Forms Plugin, Dynamic Tabs

    - by user177874
    Hi guys, I am using JQuery UI tabs. When i create a tab using the "$("#" + target).tabs('add', url, title);" method it opens a tab and calls an ajax form correctly.. Now the problem exists when i open an identical tab containing the identical form. When the form is submitted using the forms plugin, things mess up. I am presuming this is due to multiple areas having the same div id and so the form plugin does not know which to update.. Is there a work around for this at all ??

  • jQuery Ajax post with dynamic url

    - by morpheous
    I want to send an AJAX POST, but I want the url that the data is sent to, to be derived from the id of the element that was clicked. This is what I have so far: I have written a javascript function (get_my_url) that returns a url, depending on the element id that was passed to the function. The problem is, it is not clear how to bind the function (get_my_url) to the url param of the .ajax() method. jQuery('.elem1').click(function(){ jQuery.ajax({ async: false, type: 'POST', url: get_my_url(jQuery(this).attr('id')), data: 'id1=1', dataType: 'json', success: function(data){ msg = data.msg }, error: function(xrq, status, et){msg='Oops. An error occured!'} }); Does anyone know how to pass a function to the url param?

  • CSS: semi-transparent background, but not text

    - by Stijn Sanders
    Is there a way in CSS to make the background of an element semi-transparent, but still have the text of the element non-transparent? (Without separating the text and background in two elements positioned over eachother.) I've tried <p style="position:absolute;background-color:green;filter:alpha(opacity=60);opacity:.6;"><span style="color:white;filter:alpha(opacity=100);opacity:1;">Hello world</span></p> But it looks like child elements are subjected to the opacity of their parent(s), so 'opacity:1' is still drawn as 'opacity:.6' from the parent.

  • How to pass dynamic values using MVC AJax.BeginForm

    - by Arthur
    I'm using MVC and AJax.BeginForm to do some ajax updating of my page. The BeginForm code looks something like: using (Ajax.BeginForm("HandleCrop", "Card", new { accept = true, id = Model.ImageUpload.ID, file = Model.ImageUpload.File, imageCropX = Model.CropInfo.X, imageCropY = Model.CropInfo.Y, imageCropWidth = Model.CropInfo.Width, imageCropHeight = Model.CropInfo.Height }, new AjaxOptions { HttpMethod = "POST", OnComplete = "ConfirmCompleted", OnSuccess = "ReloadUpload", OnFailure = "Failure" }, null)) The Model.CropInfo is being put in as hidden fields like so: <%=Html.HiddenFor(m => m.CropInfo.X) %> <%=Html.HiddenFor(m => m.CropInfo.Y) %> <%=Html.HiddenFor(m => m.CropInfo.Width) %> <%=Html.HiddenFor(m => m.CropInfo.Height) %> However, these values are being dynamically modified by some client side javascript, and these values need to be posted through the Ajax call back to the server. The above code will obviously not work as the imageCrop.. parameters in the Ajax form are being filled when the page is rendered (therefore being all 0). My question is: what is the correct way to approach this situation?

  • dynamic button in jsp

    - by kawtousse
    hi everyone, in my jsp i have a table constructed dynamically like the following: retour.append("<tr>"); try { s= HibernateUtil.currentSession(); tx=s.beginTransaction(); Query query = s.createQuery(HQL_QUERY); for(Iterator it=query.iterate();it.hasNext();) { if(it.hasNext()){ Dailytimesheet object=(Dailytimesheet)it.next(); retour.append("<td>" +object.getActivity() +"</td>"); retour.append("<td>" +object.getProjectCode() + "</td>"); retour.append("<td>" +object.getWAName() + "</td>"); retour.append("<td>" +object.getTaskCode() +"</td>"); retour.append("<td>" +object.getTimeFrom() +"</td>"); retour.append("<td>" +object.getTimeSpent() + "</td>"); retour.append("<td>" +object.getPercentTaskComplete() + "</td>"); if (droitdaccess) { retour.append(""); retour.append(""); retour.append(""); retour.append("<td bordercolor=#FFFFFF>"); retour.append("<input type=\"hidden\" id=\"id_"+nomTab+"_"+compteur+"\" value=\""+object.getIdDailyTimeSheet()+"\"/>"); retour.append("<img src=\"icon_delete.gif\" onClick=\"deletearowById('id_"+nomTab+"_"+compteur+"')\" style=\"cursor:pointer\" name=\"action\" value=\"deleting\" />"); retour.append("</td>"); } } compteur++; retour.append("</tr>"); } //terminer la table. retour.append ("</table>"); next to the table i want to display a button named send in order to send the table content. I do not really want to dispaly this button where the table is empty. So at least if the table is populated by nly one record i want that button being displayed. How should i deal in this case. Thanks.

  • Dynamic margin (or simulation of margin) between left floated divs

    - by BugBusterX
    I have a number of divs floated left. When browser is resized they move down or up based on how many can fit on the line. I was wondering if there is a way to dynamically (with css) have those divs align (or have margin) in a way, that they would always fill the entire screen space by having their marhin resize? In other words margin between them would resize while browser is resized, but as soon as another div can fit it will be added in the line, or if minimum margin is reached and passed another div goes to next line while margins expand again. Here's an example how it is now, resize the wondow to see he leftover space that I want to "fill" <html> <head> <style> .test { float:left; width: 100px; height:100px; background-color: grey; margin: 0 10px 10px 0; } </style> </head> <body> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> <div class="test"></div> </body> </html>

  • How to implement a download for dynamic files in asp.net with masterpages

    - by Tim
    Hello, the title says it all. I have seen some similar questions on SO like this or this, but either i have overlooked something or my requirement is different, neither works. My situation is following: i have a Masterpage one of its contentpage is called MasterData.aspx MasterData has an asp.net ajax tabcontainer control with one usercontrol in every tabpanel these usercontrols(f.e. MD_Customer.ascx)hold the main content(like a normal page) they all have GridViews in it and i want to provide an Excel-Export-Button What i've tried is is to use an iframe like here. But the function that adds the iframe to the document gets never called and therefore i never see the save-as-dialog. Maybe this is caused by using a MasterPage. Does somebody has an idea on how to provide a button in an UpdatePanel that causes an async postback, so that i can generate a CSV dynamically in codebehind and write it to the response? Thank you in advance. aspx-markup: <asp:UpdatePanel ID="UpdGridInfo" runat="server" > <ContentTemplate> <asp:Label ID="LblInfo" Font-Underline="false" runat="server" CssClass="content" ></asp:Label>&nbsp;&nbsp; <asp:ImageButton ToolTip="export to Excel" style="vertical-align:bottom" ID="BtnExcelExport" ImageUrl="~/images/excel2007logo.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> and the BtnExportExcel codebehind handler(of course it cannot work to write the csv to the response of this page): Private Sub BtnExcelExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles BtnExcelExport.Click Dim csv As String = tableToCsv(DirectCast(Me.GridSource, DataTable)) Response.AddHeader("Content-disposition", "attachment; filename=RuleConfigurationFile.csv") Response.ContentType = "application/octet-stream" Response.Write(csv) Response.End() End Sub

  • VBA Tab Key putting actual Tab Value in Text Box instead of navigating to next control

    - by ray023
    I have a VBA form (in Excel if that matters) that contains text boxes. On three occasions, I have found myself pressing the tab key to navigate to the next control, but instead an actual TAB is being put in the text box. The form normally acts as it should, but it does concern me that this gremlin is showing up sporadically. It has shown up on Office 2003 as well as Office 2007 on two different computers. Has anyone else encountered this problem and, if so, how did you fix it?

  • Trying to draw a dynamic rectangle in SVG

    - by Shaun
    To be more specific, here are the steps I need: onmousedown - set x and y of rect as mouse coordinates onmousemove - using the current x and y mouse coordinates calculate height and width of the rect, set these and append onmouseup - remove the rectangle, and call a function based off some calculations from the rect. Here is what I have but isn't quite working (right now I have it drawing a line to make it simpler): onmousedown: startbox(evt) function startbox(evt) { if(evt.button === 0) { x1 = evt.clientX + div.scrollLeft-5; y1 = evt.clientY + div.scrollTop-30; obj.setAttributeNS(null, "x1", x1); obj.setAttributeNS(null, "y1", y1); Root.setAttributeNS(null, "onmousemove", "updatebox(evt)"); } } onmousemove: updatebox(evt) function updatebox(evt) { if(evt.button === 0) { x2 = evt.clientX + div.scrollLeft-5; y2 = evt.clientY + div.scrollTop-30; Root.appendChild(.obj); w = Math.abs(x2-x1); h = Math.abs(y2-y1); var strokecolor; if(w>20 && h>20) { strokecolor = "green"; validbox = true; } else { strokecolor = "red"; validbox = false; } var Attr={ x2:x2, y2:y2, stroke:strokecolor } assignAttr(obj, Attr); //just loops thru adding multiple attributes } } onmouseup: endbox() function endbox(evt) { if(evt.button===0) { Root.setAttributeNS(null, "onmousemove", ""); Root.removeChild(obj); if(validbox) { //do stuff validbox = !validbox; } } } Some of my problems with this are: Its slow in Chrome making drawing the line/rect feel sluggish. It won't work two times in a row. This is the real problem that I can't fix. Any and all feedback is welcome.

  • Separation of static and dynamic content in Java EE applications

    - by Dan
    We work with IBM products and we typically use IBM Http Servers (read Apache) as a reverse proxy for our application servers. For performance reasons we serve static content (.gif, .jpg, .css, .html etc.) from our http servers, to ease the burden a bit from the application server. So far, we have to distribute files to http server and configure it manually (writing custom scripts at best.) The problem is the effort needed to keep everything in synch, especially when you need to update the app. Does any Java EE product support this “out of the box”? Is there a way to have application server do this automatically, like in cluster configuration for example, where master node is in charge of distributing the application to other nodes and for keeping everything in synch.

  • Get the equivalent time between "dynamic" time zones

    - by doctore
    I have a table providers that has three columns (containing more columns but not important in this case): starttime, start time in which you can contact him. endtime, final hour in which you can contact him. region_id, region where the provider resides. In USA: California, Texas, etc. In UK: England, Scotland, etc starttime and endtime are time without timezone columns, but, "indirectly", their value has time zone of the region in which the provider resides. For example: starttime | endtime | region_id (time zone of region) | "real" st | "real" et ----------|----------|---------------------------------|-----------|----------- 03:00:00 | 17:00:00 | 1 (EGT => -1) | 02:00:00 | 16:00:00 Often I need to get the list of suppliers whose time range is within the current server time (taking into account the time zone conversion). The problem is that the time zones aren't "constant", ie, they may change during the summer time. However, this change is very specific to the region and not always carried out at the same time: EGT <= EGST, ART <= ARST, etc. The question is: 1. Is it necessary to use a webservice to update every so often the time zones in the regions? Does anyone know of a web service that can serve? 2. Is there a better approach to solve this problem? Thanks in advance. UPDATE I will give an example to clarify what I'm trying to get. In the table providers I found this records: idproviders | starttime | endtime | region_id ------------|-----------|----------|----------- 1 | 03:00:00 | 17:00:00 | 23 (Texas) 2 | 04:00:00 | 18:00:00 | 23 (Texas) If I execute the query in January, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +1 hour Server time = 02:00:00 I should get the following results: idproviders = 1 If I execute the query in June, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +2 hours (their local time has not changed, but their time zone has changed) Server time = 02:00:00 I should get the following results: idproviders = 1 and 2

  • C dynamic memory allocation for table of structs

    Hi here is my code. I want to dynamincly change no of elemnts in table with structs __state: typedef struct __state{ long int timestamp; int val; int prev_value; }*state_p, state_t; int main(int argc, char **argv){ int zm; int previous_state = 0; int state = 0; int i = 0; int j; state_p st; //here i want to have 20 structs st. st = (state_p) malloc(sizeof(state_t) * 20); while(1){ previous_state = state; scanf("%d", &state); printf("%d, %d\n", state, previous_state); if (previous_state != state){ printf("state changed %d %d\n", previous_state, state); // here i got compile error: main.c: In function ‘main’: main.c:30: error: incompatible type for argument 1 of ‘save_state’ main.c:34: error: invalid type argument of ‘->’ main.c:34: error: invalid type argument of ‘->’ save_state(st[i],previous_state, state); } i++; } return 0; } I suppose i have to change that st[i] to smth like st+ptr ? where pointer is incermeting in each loop iteration ? Or am I wrong ? When i change code: initialization into state_p st[20] and in each loop iteration i put st[i] = (state_p)malloc(sizeof(state_t)) everything works fine, but i want to dynammicly change number of elemets in that table. Thx in advance for any help

  • I need to display users current location as text

    - by Taylor Satula
    Hi, I am new to iPhone development and really have no idea how to do what I am trying to implement. Here is my problem, I need to display the users current street and city as text in my iPhone app (See picture). I have seen many posts on stack overflow and other websites about how to do this but they are all just code examples. As I said before, I am a extreme beginner. I just need to show the MKReverseGeocoder and its output as text in my application. If someone could walk me through how/where to create the ReverseGeocoder and how to make it show up in my application I would be extremely grateful. I have searched for hours trying to find a beginner example but alas I cannot find one that lays it out step by step. I hope this can help me out.

  • Use of text() function when using xPath in dom4j

    - by jlawless
    I have inherited an application that parses xml using dom4j and xPath: The xml being parsed is similar to the following: <cache> <content> <transaction> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77145</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77147</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_PROCESSING</widget> <widget name="TRANS_DETAIL_ID">77152</widget> <widget name="GRD_ERRORS" /> </page> </transaction> </content> </cache> Individual Nodes are being searched using the following: String xPathToGridErrorNode = "//cache/content/transaction/page/widget[@name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']/../widget[@name='TRANS_DETAIL_ID'][text()='77147']/../widget[@name='GRD_ERRORS_TEMP']"; org.dom4j.Element root = null; SAXReader reader = new SAXReader(); Document document = reader.read(new BufferedInputStream(new ByteArrayInputStream(xmlToParse.getBytes()))); root = document.getRootElement(); Node gridNode = root.selectSingleNode(xPathToGridErrorNode); where xmlToParse is a String of xml similar to the excerpt provided above. The code is trying to obtain the GRD_ERROR node for the page with the PAGE_ID and TRANS_DETAIL_ID provided in the xPath. I am seeing an intermittent (~1-2%) failure (returned node is null) of this selectSingleNode request even though the requested node is in the xml being searched. I know there are some gotchas associated with using text()= in xPath and was wondering if there was a better way to format the xPath string for this type of search.

  • bulleted lists for plain-text documents in Vim

    - by AnC
    While Vim supports automatic indenting in lists, the default setting only covers ordered lists, starting with digits: 1. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim 2. veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. I have not been able to figure out how to extend this to unordered, bulleted lists: * Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim * veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Changing the formatlistpat RegEx did not lead to the desired results (indeed, it even broke ordered lists). Any help would be appreciated!

  • Getting the DirectShow VideoRender filter to respond to MediaType changes on its Input Pin?

    - by Jonathan Websdale
    Below is the code extract from my decoder transform filter which takes in data from my source filter which is taking RTP network data from an IP camera. The source filter, decode filter can dynamically respond to changes in the camera image dimensions since I need to handle resolution changes in the decode library. I've used the 'ReceiveConnection' method as described in the DirectShow help, passing the new MediaType data in the next sample. However, I can't get the Video Mixing Renderer to accept the resolution changes dynamically even though the renderer will render the different resolution if the graph is stopped and restarted. Can anyone point out what I need to do to get the renderer to handle dynamic resolution changes? HRESULT CDecoder::Receive(IMediaSample* pIn) { //Input data does not necessarily correspond one-to-one //with output frames, so we must override Receive instead //of Transform. HRESULT hr = S_OK; //Deliver input to library long cBytes = pIn->GetActualDataLength(); BYTE* pSrc; pIn->GetPointer(&pSrc); try { hr = m_codec.Decode(pSrc, cBytes, (hr == S_OK)?&tStart : NULL); } catch (...) { hr = E_UNEXPECTED; } if (FAILED(hr)) { if (theLog.enabled()){theLog.strm() << "Decoder Error " << hex << hr << dec << " - resetting input"; theLog.write();} //Force reset of decoder m_bReset = true; m_codec.ResetInput(); //We have handled the error -- don't pass upstream or the source may stop. return S_OK; } //Extract and deliver any decoded frames hr = DeliverDecodedFrames(); return hr; } HRESULT CDecoder::DeliverDecodedFrames() { HRESULT hr = S_OK; for (;;) { DecodedFrame frame; bool bFrame = m_codec.GetDecodedFrame(frame); if (!bFrame) { break; } CMediaType mtIn; CMediaType mtOut; GetMediaType( PINDIR_INPUT, &mtIn); GetMediaType( PINDIR_OUTPUT, &mtOut); //Get the output pin's current image resolution VIDEOINFOHEADER* pvi = (VIDEOINFOHEADER*)mtOut.Format(); if( pvi->bmiHeader.biWidth != m_cxInput || pvi->bmiHeader.biHeight != m_cyInput) { HRESULT hr = GetPin(PINDIR_OUTPUT)->GetConnected()->ReceiveConnection(GetPin(PINDIR_OUTPUT), &mtIn); if(SUCCEEDED(hr)) { SetMediaType(PINDIR_OUTPUT, &mtIn); } } IMediaSamplePtr pOut; hr = m_pOutput->GetDeliveryBuffer(&pOut, 0, 0, NULL); if (FAILED(hr)) { break; } AM_MEDIA_TYPE* pmt; if (pOut->GetMediaType(&pmt) == S_OK) { CMediaType mt(*pmt); DeleteMediaType(pmt); SetMediaType(PINDIR_OUTPUT, &mt); pOut->SetMediaType(&mt); } // crop, tramslate and deliver BYTE* pDest; pOut->GetPointer(&pDest); m_pConverter->Convert(frame.Width(), frame.Height(), frame.GetY(), frame.GetU(), frame.GetV(), pDest); pOut->SetActualDataLength(m_pOutput->CurrentMediaType().GetSampleSize()); pOut->SetSyncPoint(true); if (frame.HasTimestamp()) { REFERENCE_TIME tStart = frame.Timestamp(); REFERENCE_TIME tStop = tStart+1; pOut->SetTime(&tStart, &tStop); } m_pOutput->Deliver(pOut); } return hr; }
