  • Export Multiple Crystal Reports ASP.NET

    - by AProgrammer
    Hey all, I want to export 2 different reports when I click an Export button. The problem is the routine only fires once and I only get one report to print out. Am I doing something wrong? I think it has something to do with the HTTPResponse, but I'm not sure. Here's my code: Dim badgeSize As Integer = 0 'Drop Down selection Dim badgeData As New DataSet 'Visitor Badge Data Dim badgeEmployeeData As New DataSet 'Employee Badge Data Dim badgeTotals As Integer = 0 'Totals for both badgeSize = ddlBadgeSize.SelectedValue ' Get Visitor Data badgeData = _DatabaseAccess.GetProjectReportData(sessionInfo.myEventID, sessionInfo.EventCreator) ' Get Employee Data badgeEmployeeData = _DatabaseAccess.GetProjectReportEmployeeData(sessionInfo.myEventID, sessionInfo.EventCreator) 'Obtain Totals badgeTotals = badgeData.Tables(0).Rows.Count + badgeEmployeeData.Tables(0).Rows.Count If badgeTotals = 0 Then ShowMessage("There are no badges to print.") Exit Sub End If If badgeSize.Equals(0) Then 'Small If badgeEmployeeData.Tables(0).Rows.Count > 0 Then If badgeEmployeeData.Tables(0).Rows.Count >= 6 Then PrintProjectBadges(badgeEmployeeData, "Employee", badgeSize) Else PrintStandardDymo(badgeEmployeeData, "Employee", 1) End If End If If badgeData.Tables(0).Rows.Count > 0 Then If badgeData.Tables(0).Rows.Count >= 6 Then PrintProjectBadges(badgeData, "Visitor", badgeSize) Else PrintStandardDymo(badgeData, "Visitor", 1) End If End If else 'do somethign else endif And the Report Code: Private Sub PrintProjectBadges(ByVal theData As DataSet, ByVal badgeType As String, ByVal badgeSize As Integer) Dim ourReport As New ReportDocument Dim crConnectionInfo As New ConnectionInfo(SetCrystalConnection) If badgeSize = 0 Then Try If badgeType = "Visitor" Then ourReport.Load(Server.MapPath("SmallProjectBadge.rpt"), OpenReportMethod.OpenReportByDefault) 'LIVE SERVER USE Else ourReport.Load(Server.MapPath("SmallProjectEmployeeBadge.rpt"), OpenReportMethod.OpenReportByDefault) 'LIVE SERVER USE End If Catch ex As Exception Dim TraceList As New ArrayList TraceList.Add("DBLog") DatabaseAccess.WriteToErrorLog("Visitor Registration", "Printing Project Badges", ex.Message, TraceEventType.Information, 1, TraceList) Exit Sub End Try ourReport.SetDataSource(theData.Tables("Project")) Else 'Do somethign else...

  • dotnetopenauth with asp.net mvc proving too frustrating to use.

    - by Stacey
    I've been trying excessively hard to implement a good open id solution into asp.net mvc - and everywhere I turn is absolute dead ends. DotNetOpenAuth is just too big and I have been thusfar unable to get even the most simplistic, basic, absolute cut and dry implementation of it to work. NerdDinner had a promising implementation, but it is impossible to track down all of the dependant files and scripts. The DotNetOpenAuth website has virtually no information that helps, either, unfortunately. Does ANYONE know of a simple approach to just implementing this that actually explains and details how it is working with some kind of selector? It is talked about so much, but everything I find for it is so difficult to work with that it is really putting my whole team off from even considering it. We want to implement it similar to how stack overflow already does - using a selector that'll popup a login page if it needs to. I realize there is a lot of code that needs to be done for this, but everything just hails and praises dotnetopenauth, and nothing really teaches it. Even the sample projects do not open or compile. It looks like a wonderful library - but it really just isn't clicking for me.

  • MXML composite canvas component initialization error

    - by mkorpela
    I'm getting an odd error from my composite canvas component: An ActionScript error has occurred: Error: null at mx.core::Container/initialize()[C:\autobuild\galaga\frameworks\projects\framework\src\mx\core\Container.as:2560] at -REMOVED THIS FOR STACK OVERFLOW-.view::EditableCanvas/initialize()[.../view/EditableCanvas .... It seems to be related to the fact that my composite component has a child and I'm trying to add one in the place I'm using the component. So how can I do this correctly? Component code looks like this (EditableCanvas.mxml): <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="{init()}"> <mx:Script> <![CDATA[ private var _editable:Boolean; public function set editable(edit:Boolean):void { _editable = edit; } private function init():void { if(_editable){ addEventListener(MouseEvent.MOUSE_OVER, showEdit); addEventListener(MouseEvent.MOUSE_OUT, hideEdit); } } private function showEdit(event:Event):void { editTextImage.visible = true; } private function hideEdit(event:Event):void { editTextImage.visible = false; } ]]> </mx:Script> <mx:Image id="editTextImage" source="@Embed('/../assets/icons/small/process.png')" click="{dispatchEvent(EditPoiEvent.text())}" visible="false"/> </mx:Canvas> The code that is using the code looks like this: <view:EditableCanvas width="290" height="120" backgroundColor="#FFFFFF" horizontalScrollPolicy="off" borderStyle="solid" cornerRadius="3" editable="{_editable}"> <mx:Text id="textContentBox" width="270" fontFamily="nautics" fontSize="12" text="{_text}"/> </view:EditableCanvas>

  • How can UISearchDisplayController autorelease cause crash in a different view controller?

    - by Tofrizer
    Hi, I have two view controllers A and B. From A, I navigate to view controller B as follows: // in View Controller A // navigateToB method -(void) navigateToB { BViewController *bViewController = [[BViewController alloc] initWithNibName: @"BView" bundle:nil]; bViewController.bProperty1 = SOME_STRING_CONSTANT; bViewController.title = @"A TITLE OF A VC's CHOOSING"; [self.navigationController pushViewController: bViewController animated:YES]; [bViewController release]; //<----- releasing 0x406c1e0 } In BViewController, the property bPropery1 is defined with copy as below (note, B also contains UITableView and other properties): @property (nonatomic, copy) NSString *bProperty1; Everything appeared to work fine when navigating back and forth between A and B. That is until I added a UISearchDisplayController to the table view contained in BViewController. Now when I navigate out of B, back to A, the app crashes. Stack trace shows what looks the search display controller being autoreleased at time of crash: #0 0x009663a7 in ___forwarding___ #1 0x009426c2 in __forwarding_prep_0___ #2 0x018c8539 in -[UISearchDisplayController _destroyManagedTableView] #3 0x018c8ea4 in -[UISearchDisplayController dealloc] #4 0x00285ce5 in NSPopAutoreleasePool NSZombies shows: -[BViewController respondsToSelector:]: message sent to deallocated instance 0x406c1e0 And malloc history on this points to the bViewController already released in A's navigateToB method above: Call [2] [arg=132]: thread_a065e720 |start ... <snip> ..._sendActionsForEvents:withEvent:] | -[UIControl sendAction:to:forEvent:] | - [UIApplication sendAction:to:from:forEvent:] | -[**AViewController navigateToB**] | +[NSObject alloc] | +[NSObject allocWithZone:] | _internal_class_createInstance | _internal_class_createInstanceFromZone | calloc | malloc_zone_calloc Can someone please give me any ideas on what is happening here? In navigateToB method, once the bViewController is released (after pushViewController), that's should be it for bViewController. Nothing else even knows about it as it is local to the navigateToB method block and it has been released. When navigating from B back to A, nothing is invoked in viewDidLoad, viewWillAppear etc that will re-enter navigateToB. It looks like somehow search display controller has a reference to something in my AViewController and so as it is autoreleased it is taking this "something" down with it but I cannot understand how this is possible, especially as I'm using copy to pass data between A and B. I'm going potty over this. I'm sure this is my mistake somewhere and so I turn to you, Stack Overflow legends for any words of wisdom or advice on how to resolve this. Many Thanks.

  • C# Error reading two dates from a binary file

    - by Jamie
    Hi all, When reading two dates from a binary file I'm seeing the error below: "The output char buffer is too small to contain the decoded characters, encoding 'Unicode (UTF-8)' fallback 'System.Text.DecoderReplacementFallback'. Parameter name: chars" My code is below: static DateTime[] ReadDates() { System.IO.FileStream appData = new System.IO.FileStream( appDataFile, System.IO.FileMode.Open, System.IO.FileAccess.Read); List<DateTime> result = new List<DateTime>(); using (System.IO.BinaryReader br = new System.IO.BinaryReader(appData)) { while (br.PeekChar() > 0) { result.Add(new DateTime(br.ReadInt64())); } br.Close(); } return result.ToArray(); } static void WriteDates(IEnumerable<DateTime> dates) { System.IO.FileStream appData = new System.IO.FileStream( appDataFile, System.IO.FileMode.Create, System.IO.FileAccess.Write); List<DateTime> result = new List<DateTime>(); using (System.IO.BinaryWriter bw = new System.IO.BinaryWriter(appData)) { foreach (DateTime date in dates) bw.Write(date.Ticks); bw.Close(); } } What could be the cause? Thanks

  • Best approach to storing image pixels in bottom-up order in Java

    - by finnw
    I have an array of bytes representing an image in Windows BMP format and I would like my library to present it to the Java application as a BufferedImage, without copying the pixel data. The main problem is that all implementations of Raster in the JDK store image pixels in top-down, left-to-right order whereas BMP pixel data is stored bottom-up, left-to-right. If this is not compensated for, the resulting image will be flipped vertically. The most obvious "solution" is to set the SampleModel's scanlineStride property to a negative value and change the band offsets (or the DataBuffer's array offset) to point to the top-left pixel, i.e. the first pixel of the last line in the array. Unfortunately this does not work because all of the SampleModel constructors throw an exception if given a negative scanlineStride argument. I am currently working around it by forcing the scanlineStride field to a negative value using reflection, but I would like to do it in a cleaner and more portable way if possible. e.g. is there another way to fool the Raster or SampleModel into arranging the pixels in bottom-up order but without breaking encapsulation? Or is there a library somewhere that will wrap the Raster and SampleModel, presenting the pixel rows in reverse order? I would prefer to avoid the following approaches: Copying the whole image (for performance reasons. The code must process hundreds of large (= 1Mpixels) images per second and although the whole image must be available to the application, it will normally access only a tiny (but hard-to-predict) portion of the image.) Modifying the DataBuffer to perform coordinate transformation (this actually works but is another "dirty" solution because the buffer should not need to know about the scanline/pixel layout.) Re-implementing the Raster and/or SampleModel interfaces from scratch (but I have a hunch that I will be unable to avoid this.)

  • Why do people say that Ruby is slow?

    - by stephen murdoch
    I like Ruby on Rails and I use it for all my web development projects. A few years ago there was a lot of talk about Rails being a memory hog and about how it didn't scale very well but these suggestions were put to bed by Gregg Pollack here. Lately though, I've been hearing people saying that Ruby itself is slow. Why is Ruby considered slow? I do not find Ruby to be slow but then again, I'm just using it to make simple CRUD apps and company blogs. What sort of projects would I need to be doing before I find Ruby becoming slow? Or is this slowness just something that affects all programming languages? What are your options as a Ruby programmer if you want to deal with this "slowness"? Which version of Ruby would best suit an application like Stack Overflow where speed is critical and traffic is intense? The questions are subjective, and I realise that architectural setup (EC2 vs standalone servers etc) makes a big difference but I'd like to hear what people think about Ruby being slow. Finally, I can't find much news on Ruby 2.0 - I take it we're a good few years away from that then?

  • Investigating the root cause behind SharePoint's "request not found in the TrackedRequests"

    - by Muhimbi
    We have a long standing issue in our bug tracking system about the dreaded "ERROR: request not found in the TrackedRequests. We might be creating and closing webs on different threads." message in SharePoint's trace log. As we develop Workflow software for the SharePoint market, we look into this issue from time to time to make sure it is not caused by our products. I have personally come to the conclusion that this is a problem in SharePoint, but perhaps someone else can prove me wrong. Here is what I know: According to the hundreds of search results returned by Google on this topic, this issue appears to be mainly related to SharePoint Workflows, both SharePoint Designer and Visual Studio based workflows. Assuming ULS logging is set to Monitorable, the easiest way to reproduce this problem is to create a new SharePoint Designer Workflow, attach it to a document library, set it to auto start on add/update, don't add any actions, save the workflow and upload a file to the document library. The error is only visible in the SharePoint trace log, it does not appear to impact the execution of the workflow at hand. I have verified that the problem occurs on 32 bit as well as 64 bit systems, Win2K3 and 2K8, WSS and MOSS with SharePoint versions up to the December 2009 Cumulative Update (6524). The problem does not occur when a workflow is started manually. There are dozens of related posts on MSDN Forums, hundreds on Google, one on StackOverflow and none on SharePoint Overflow. There appears to be no answer. Does anyone have any idea about what is going on, what is causing this and if we should worry or file this under 'Red Herrings'.

  • Convert function to read from string instead of file in C

    - by Dusty
    I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure: static int LoadFromFile(FILE *Stream, ConfigStructure *cs) { int tempInt; ... if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 ) { printf("Unable to read version number\n"); return 0; } cs->Version = tempInt; ... } to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this: static int LoadFromString(char *Stream, ConfigStructure *cs) A few things to note: The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward compatible manner, which makes duplication of the overall logic quite a pain. The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in in a backwards compatible manner. I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually. This has to remain in C, so no C++ functionality like streams can help here Am I missing a better option? Is there some way to create a FILE * that actually just points to a location in memory instead of on disk? Any pointers, suggestions or other help is greatly appreciated.

  • Is there a standard mapping between JSON and Protocol Buffers?

    - by Daniel Earwicker
    From a comment on the announcement blog post: Regarding JSON: JSON is structured similarly to Protocol Buffers, but protocol buffer binary format is still smaller and faster to encode. JSON makes a great text encoding for protocol buffers, though -- it's trivial to write an encoder/decoder that converts arbitrary protocol messages to and from JSON, using protobuf reflection. This is a good way to communicate with AJAX apps, since making the user download a full protobuf decoder when they visit your page might be too much. It may be trivial to cook up a mapping, but is there a single "obvious" mapping between the two that any two separate dev teams would naturally settle on? If two products supported PB data and could interoperate because they shared the same .proto spec, I wonder if they would still be able to interoperate if they independently introduced a JSON reflection of the same spec. There might be some arbitrary decisions to be made, e.g. should enum values be represented by a string (to be human-readable a la typical JSON) or by their integer value? So is there an established mapping, and any open source implementations for generating JSON encoder/decoders from .proto specs?

  • The Coolest Parts of Windows API

    - by Andreas Rejbrand
    I have noticed that there are quite a few community wikis about "Tips & Tricks" or "Hidden Features" in programming languages and APIs here at Stack Overflow. But I could not find any about my own personal favourites: Win32 API and Delphi. Therefore I start my "own" CW about Win32 API. There are (at least) two kinds of Win API users: those that have been brought up using Windows API in C/C++, and those that have been brought up using some level of abstraction above the Windows API. I belong to the latter category, being brought up using Delphi's VCL. But over the last five years, I have become increasingly interested in the underlaying API of the Windows operating system, and today I work a lot with it. Depending on which category a programmer belongs to, he (or possibly she) will think that different things are "cool" in the Windows API. For instance, whereas a VCL-brought up developer might think it it very cool to var errIcon: HICON; begin errIcon := LoadIcon(0, IDI_ERROR); DrawIcon(Canvas.Handle, 10, 10, errIcon), a programmer brought up using Windows API in C will not be as impressed. But no matter how you are "brought up": what are the coolest "tricks" in Windows API? I start by listing a few of my own favourites, some of which are more "cool" than "useful", though: LoadIcon and MessageBeep can load/play system default icons and sounds. Open the CD tray: mciSendString('Set cdaudio door open wait', nil, 0, 0); Fade out the screen (Windows Vista and later) and turn of the monitor: SendMessage(Application.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2); GetWindowDC(GetDesktopWindow) returns the DC of the desktop.

  • Can you force a crash if a write occurs to a given memory location with finer than page granularity?

    - by Joseph Garvin
    I'm writing a program that for performance reasons uses shared memory (alternatives have been evaluated, and they are not fast enough for my task, so suggestions to not use it will be downvoted). In the shared memory region I am writing many structs of a fixed size. There is one program responsible for writing the structs into shared memory, and many clients that read from it. However, there is one member of each struct that clients need to write to (a reference count, which they will update atomically). All of the other members should be read only to the clients. Because clients need to change that one member, they can't map the shared memory region as read only. But they shouldn't be tinkering with the other members either, and since these programs are written in C++, memory corruption is possible. Ideally, it should be as difficult as possible for one client to crash another. I'm only worried about buggy clients, not malicious ones, so imperfect solutions are allowed. I can try to stop clients from overwriting by declaring the members in the header they use as const, but that won't prevent memory corruption (buffer overflows, bad casts, etc.) from overwriting. I can insert canaries, but then I have to constantly pay the cost of checking them. Instead of storing the reference count member directly, I could store a pointer to the actual data in a separate mapped write only page, while keeping the structs in read only mapped pages. This will work, the OS will force my application to crash if I try to write to the pointed to data, but indirect storage can be undesirable when trying to write lock free algorithms, because needing to follow another level of indirection can change whether something can be done atomically. Is there any way to mark smaller areas of memory such that writing them will cause your app to blow up? Some platforms have hardware watchpoints, and maybe I could activate one of those with inline assembly, but I'd be limited to only 4 at a time on 32-bit x86 and each one could only cover part of the struct because they're limited to 4 bytes. It'd also make my program painful to debug ;)

  • Overlaying 2D paths on UIImage without scaling artifacts

    - by tat0
    I need to draw a path along the shape of an image in a way that it is always matching its position on the image independent of the image scale. Think of this like the hybrid view of Google Maps where streets names and roads are superimposed on top of the aerial pictures. Furthermore, this path will be drawn by the user's finger movements and I need to be able to retrieve the path keypoints on the image pixel coordinates. The user zooms-in in order to more precisely set the paths location. I manage to somehow make it work using this approach: -Create a custom UIView called CanvasView that handles touches interaction and delivers scaling, rotation, translation values to either the UIImageView or PathsView (see bellow) depending on a flag: deliverToImageOrPaths. -Create a UIImageView holding the base image. This is set as a children of CanvasView -Create a custom UIView called PathsView that keeps track of the 2D paths geometry and draws itself with a custom drawRect. This is set as children of the UIImageView. So hierarchy: CanvasView - UIImageView -PathsView In this way when deliverToImageOrPaths is YES, finger gestures transforms both the UIImageView and its child PathsView. When deliverToImageOrPaths is NO the gestures affect only the PathsView altering its geometry. So far so good. QUESTION: The problem I have is that when scaling the base UIImageView (via its .transform property) the PathsView is scaled with aliasing artifacts. drawRect is still being called on the PathsView but I guess it's performing the drawing using the original buffer size and then interpolating. How can I solve this issue? Are there better ways to implement these features? PS: I tried changing the PathsView layer class to CATiledLayer with levelsOfDetailBias 4 and levelsOfDetail 4. It solves the aliasing problem to some extent but it's unacceptable slow to render.

  • Disassembling with python - no easy solution?

    - by Abc4599
    Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

  • What is the right way to make a new XMLHttpRequest from an RJS response in Ruby on Rails?

    - by Yuri Baranov
    I'm trying to come closer to a solution for the problem of my previous question. The scheme I would like to try is following: User requests an action from RoR controller. Action makes some database queries, makes some calculations, sets some session variable(s) and returns some RJS code as the response. This code could either update a progress bar and make another ajax request. display the final result (e.g. a chart grahic) if all the processing is finished The browser evaluates the javascript representation of the RJS. It may make another (recursive? Is recursion allowed at all?) request, or just display the result for the user. So, my question this time is: how can I embed a XMLHttpRequest call into rjs code properly? Some things I'd like to know are: Should I create a new thread to avoid stack overflow. What rails helpers (if any) should I use? Have anybody ever done something similar before on Rails or with other frameworks? Is my idea sane?

Due to the permissiveness of HTML, all three of the following are legal markup: <table id="foo"><tr>...</tr></table> <table id="foo"><tbody><tr>...</tr></tbody></table> <table id="foo"><tr>...</tr><tbody><tr>...</tr></tbody></table> You are worried about tables nested in tables, and so don't want to use an XPath like table[@id="foo"]//tr. If you could specify your desired XPath as a regex, it might look something like: table[@id="foo"](/tbody)?/tr In general, how can you specify an XPath expression that allows an optional element in the hierarchy of a selector? To be clear, I'm not trying to solve a real-world problem or select a specific element of a specific document. I'm asking for techniques to solve a class of problems.

  • Resizing window causes black strips

    - by Paja
    I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything, listening for WM_ERASEBKGND in WndProc, manually drawing the form on WM_PAINT, implementing custom double buffer, etc. Is there anything else I could try? I've found this: https://connect.microsoft.com/VisualStudio/feedback/details/522441/custom-resizing-of-system-windows-window-flickers and it looks like it is a bug in DWM, but I just hope I can do some workaround. Please note that I must use double buffering, since I want to draw pretty intense graphic presentation in the Paint event. I develop in C# .NET 2.0, Win7.

  • OpenGL behaving strangely

    - by Mk12
    OpenGL is acting very strangely for some reason. In my subclass of NSOpenGLView, I have the following code in -prepareOpenGL: - (void)prepareOpenGL { GLfloat lightAmbient[] = { 0.5f, 0.5f, 0.5f, 1.0f }; GLfloat lightDiffuse[] = { 1.0f, 1.0f, 1.0f, 1.0f }; GLfloat lightPosition[] = { 0.0f, 0.0f, 2.0f }; quality = 0; zCoord = -6; [self loadTextures]; glEnable(GL_LIGHTING); glEnable(GL_TEXTURE_2D); glShadeModel(GL_SMOOTH); glClearColor(0.2f, 0.2f, 0.2f, 0.0f); glClearDepth(1.0f); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LEQUAL); glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST); glLightfv(GL_LIGHT1, GL_AMBIENT, lightAmbient); glLightfv(GL_LIGHT1, GL_DIFFUSE, lightDiffuse); glLightfv(GL_LIGHT1, GL_POSITION, lightPosition); glEnable(GL_LIGHT1); gameState = kGameStateRunning; int i = 0; // HERE ******** [NSTimer scheduledTimerWithTimeInterval:0.03f target:self selector:@selector(processKeys) userInfo:nil repeats:YES]; // Synchronize buffer swaps with vertical refresh rate GLint swapInt = 1; [[self openGLContext] setValues:&swapInt forParameter:NSOpenGLCPSwapInterval]; // Setup and start displayLink [self setupDisplayLink]; } I wanted to assign the timer that processes key input to an ivar so that I could invalidate it when the game is paused (and reinstantiate it on resume), however when I did that (as apposed to leaving it at [NSTimer scheduledTimer…), OpenGL doesn't display the cube I draw. When I take it away, it's fine. So i tried just adding a harmless statement, int i = 0; (maked // HERE *******), and that makes the lighting not work! When I take it away, everything is fine, but when I put it back, everything is dark. Can someone come up with a rational explanation for this? Thanks.

  • Vertical-Align: A Full Explanation

    - by Livvy Jeffs
    I've been struggling with vertical alignments, a seemingly simple enough process that has a lot of idiosyncrasies throughout different languages and element types. I've done a lot of reading through stackexchange and can't seem to find a common thread of understanding. Here are the rules that I have been able to gather: 1) Vertical-align does not work in <\div>s, you have to set div {display: table-cell; vertical-align: middle} This seems like a big hassle, especially since table-cells override the height limitation even when overflow is set to hidden and expands to fit content, which means the vertical "center" is variable. I just read some source-code from Pinterest where button {vertical-align: middle}, but no other vertical-align commands seem to work. It seems as if button is by default aligned in the middle. Can someone provide a clear explanation for the vertical-align attribute? What html elements respond to vertical-align? Which html elements have default vertical-align attributes? Which html elements have non-overridable vertical-align attributes? And any clues as to understanding the idiosyncracies would help as well! Thanks in advance!

  • IPreInsertEventListener makes object dirty, causes invalid update

    - by Groxx
    In NHibernate 2.1.2: I'm attempting to set a created timestamp on insert, as demonstrated here. I have this: public bool OnPreInsert(PreInsertEvent @event) { if (@event.Entity is IHaveCreatedTimestamp) { DateTime dt = DateTime.Now; string Created = ((IHaveCreatedTimestamp)@event.Entity).CreatedPropertyName; SetState(@event.Persister, @event.State, Created, dt); @event.Entity.GetType().GetProperty(Created).SetValue(@event.Entity, dt, null); } // return true to veto the insert return false; } The problem is that doing this (or duplicating Ayende's example precisely, or reordering or removing lines) causes an update after the insert. The insert uses the correct "now" value, @p6 = 3/8/2011 5:41:22 PM, but the update tries to set the Created column to @p6 = 1/1/0001 12:00:00 AM, which is outside MSSQL's range: Test 'CanInsertAndDeleteInserted' failed: System.Data.SqlTypes.SqlTypeException : SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. I've tried the same thing with the PerformSaveOrUpdate listener, described here, but that also causes an update and an insert, and elsewhere there have been mentions of avoiding it because it is called regardless of if the object is dirty or not :/ Searching around elsewhere, there are plenty of claims of success after setting both the state and the object to the same value, or by using the save listener, or of the cause coming from collections or other objects, but I'm not having any success.

  • How to make Doxygen ignore specific PHP functions, when generating documentation from a purely proce

    - by Senthil
    I am writing a PHP Library and I am trying out Doxygen to generate the API documentation. My library does not use OOP. All code is procedural. I use lot of helper functions which have an _ (underscore) prefix in their names. They are not part of the publicly exposed API. They are just used internally. Even though they are commented just like the API functions, I don't want them included when giving out the documentation for the API. I want Doxygen to ignore these functions. I can think of two solutions for this, but I am not able to implement either one of them. First is, I can set some configuration in Doxygen to make it ignore specific function name patterns. I went through Doxygen help documentation and searched the web. There seems to be options to ignore file and folder name patterns. But I am not able to find an option to specify a function name pattern and make it ignore those functions. Second is, along with all the other content in the comments above functions, I could add some other keyword or something and make Doxygen ignore those functions. I haven't been able to find out how to do that either. How can I make Doxygen ignore specific PHP functions when generating documentation? Update I searched within Stack Overflow and came across this question. It looked similar to my question. I found out about EXCLUDE_SYMBOLS config option in one of the answers. You can use that to exclude function names too. More importantly, wildcards were supported. So I am able to ignore all my functions with _ as the prefix :) This ridiculous! I should've done more research :| Someone please delete this question or add this answer as an answer.
