• How can you load a font (TTF) from a file using Core Text?

  - by minus1

  Prior to OSX 10.6, ATSFontActivateFromFileSpecification/ATSFontActivateFromFileReference were available and could be used to load a font from a file. I can't find anything similar in Core Text.

• What causes Python "Interpreter not Initialized" error?

  - by ?????

  I'm now on my third full day this week of trying to get OpenCV to work with Python. (I have been trying on and off for the past 6 months). I get this error Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. dlopen("/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so", 2); import readline # dynamically loaded from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so >>> import cv dlopen("./cv.so", 2); Fatal Python error: Interpreter not initialized (version mismatch?) and then it crashes (core dumps). python -v gives nothing after the dlopen. Any ideas from anyone who actually knows about this error?

Is there a work around for this or any better approach? Please Help and Suggest Thanks

• Java fatal error, don't know what it means

  - by Thomas King

  It happens at the same place in my code (albeit not the first time the method is executed) but I can't make head or tail of what is wrong. (Doubly so as it's code for a robot). Be most appreciative if someone can give me an idea of what kind of problem it is. I assume it's to do with threading (multi-threaded app) but I don't really know what?!? Worried as deadline for uni project is looming!!!

• How to stop UITableView moveRowAtIndexPath from leaving blank rows upon reordering

  - by coneybeare

  I am having an issue where in reordering my UITableViewCells, the tableView is not scrolling with the cell. Only a blank row appears and any subsequent scrolling gets an Array out of bounds error without any of my code in the Stack Trace. Here is a quick video of the problem.

• Visual Studio soft-crashing when encountering XAML Errors in initialize.

  - by Aren

  I've been having some serious issues with Visual Studio 2010 as of late. It's been crashing in a peculiar way when I encounter certain types of XAML errors during the InitializeComponent() of a control/window. The program breaks and visual studio gears up like it's catching an exception (because it is) and then stops midway displaying a broken highlight in my XAML file with no details as to what is wrong. Example: There is not pop outs, or details Anywhere about what is wrong, only a callstack that points to my InitializeComponent() call. Now normally I'd just do some trial and error to fix this problem, and find out where i messed up, but the real problem isn't my code. Visual Studio is rendered completely useless at this point. It reports my application still in "Running" mode. The Stop/Break/Restart buttons on the toolbar or in the menus don't do anything (but grey out). Closing the application does not stop this behaviour, closing visual studio gets it stuck in a massive loop where it yells at me complaining every file open is not in the debug project, then repeats this process when i have exausted every open file. I have to force-close devenv.exe, and after this happening 3-4 times in a row it's a lot of wasted time (as my projects are usually pretty big and studio can be quite slow @ loading). To the point Has anyone else experienced this? How can I stop studio from locking up. Can I at LEAST get information out of this beast another way so i can fix my XAML error sooner rather than after 3-4 trial-and-error compiles yielding the same crash? Any & All help would be appreciated. Visual Studio 2010 version: 10.0.30319.1RTM Edit & Update FWIW, mostly the errors that cause this are XamlParseExceptions (I figured this out after i found what was wrong with my XAML). I think I need to be clearer though, Im not looking for the solution to my code problem, as these are usually typos / small things, I'm looking for a solution to VStudio getting all buggered up as a result. The particular error in the above image that 100% for sure caused this was a XamlParseException caused by forgetting a Value attribute on a data trigger. I've fixed that part but it still doesn't tell my why my studio becomes a lump of neutered program when a perfectly normal exception is thrown in the parsing of the XAML. Code that will cause this issue (at least for me) This is the base template WPF Application, with the following Window.xaml code. The problem is a missing Value="True" on the <DataTrigger ...> in the template. It generates a XamlParseException and Visual Studio Crashes as described above when debugging it. Final Notes The following solutions did not help me: Restarting Visual Studio Rebooting Reinstalling Visual Studio

• Application crashing when talking to oracle unless executable path contains spaces

  - by Lasse V. Karlsen

  We have an x-files problem with our .NET application. Or, rather, hybrid Win32 and .NET application. When it attempts to communicate with Oracle, it just dies. Vanishes. Goes to the big black void in the sky. No event log message, no exception, no nothing. If we simply ask the application to talk to a MS SQL Server instead, which has the effect of replacing the usage of OracleConnection and related classes with SqlConnection and related classes, it works as expected. Today we had a breakthrough. For some reason, a customer had figured out that by placing all the application files in a directory on his desktop, it worked as expected with Oracle as well. Moving the directory down to the root of the drive, or in C:\Temp or, well, around a bit, made the crash reappear. Basically it was 100% reproducable that the application worked if run from directory on desktop, and failed if run from directory in root. Today we figured out that the difference that counted was wether there was a space in the directory name or not. So, these directories would work: C:\Program Files\AppDir\Executable.exe C:\Temp Lemp\AppDir\Executable.exe C:\Documents and Settings\someuser\Desktop\AppDir\Executable.exe whereas these would not: C:\CompanyName\AppDir\Executable.exe C:\Programfiler\AppDir\Executable.exe <-- Program Files in norwegian C:\Temp\AppDir\Executable.exe I'm hoping someone reading this has seen similar behavior and have a "aha, you need to twiddle the frob on the oracle glitz driver configuration" or similar. Anyone? Followup #1: Ok, I've processed the procmon output now, both files from when I hit the button that attempts to open the window that triggers the cascade failure, and I've noticed that they keep track mostly, there's some smallish differences near the top of both files, and they they keep track a long way down. However, when one run fails, the other keeps going and the next few lines of the log output are these: ReadFile C:\oracle\product\10.2.0\db_1\BIN\orageneric10.dll SUCCESS Offset: 274 432, Length: 32 768, I/O Flags: Non-cached, Paging I/O, Synchronous Paging I/O ReadFile C:\oracle\product\10.2.0\db_1\BIN\orageneric10.dll SUCCESS Offset: 233 472, Length: 32 768, I/O Flags: Non-cached, Paging I/O, Synchronous Paging I/O After this, the working run continues to execute, and the other touches the mscorwks.dll files a few times before threads close down and the app closes. Thus, the failed run does not touch the above files. Followup #2: Figured I'd try to upgrade the oracle client drivers, but 10.2.0.1 is apparently the highest version available for Windows 2003 server and XP clients. Followup #3: Well, we've ended up with a black-box solution. Basically we found that the problem is somewhere related to XPO and Oracle. XPO has a system-table it manages, called XPObjectType, with three columns: Oid, TypeName and AssemblyName. Due to how Oracle is configured in the databases we talk to, the column names were OID, TYPENAME and ASSEMBLYNAME. This would ordinarily not be a problem, except that XPO talks to the schema information directly and checks if the table is there with the right column names, and XPO doesn't handle case differences so it sees a XPObjectType table with three unknown columns and none of those it expects. Exactly what XPO does now I don't really know, but if I dropped this table, and recreated it with the right case, using double quotes around all the column names to get the case right, the problem doesn't crop up. Exactly where the space in the folder name comes into this, I still have no idea, but this problem had two tiers: Stop the application from crashing at our customers, short-term solution Fix the bug, long-term solution Right now tier 1 is solved, tier 2 will be put back into the queue for now and prioritized. We're facing some bigger changes to our data tier anyway so this might not be a problem we need to solve, at least if all our Oracle-customers verify that the table-fix actually gets rid of the problem. I'll accept the answer by Dave Markle since though Process Monitor (the big brother of File Monitor) didn't actually pinpoint the problem, I was able to use it to determine that after my breakpoint in user-code where XPO had built up the query for this table, no I/O happened until all the entries for the application closing down was logged, which led me to believe it was this table that was the culprit, or at least influenced the problem somehow. If I manage to get to the real cause of this, I'll update the post.

• GDI+ crashes when loading PNG from IStream

  - by konforce

  I wrote something to load PNG files from a custom C++ IStream via GDI+. It worked great until I ran it on Vista machines. Crashes every time. When compiled on VS 2008, I found that inserting code into the IStream::AddRef method, such as a cout, made the problem go away. When compiling with VS 2010, it still crashes regardless of that. I stripped the program down to its basics. I copied a FileStream straight from Microsoft's documentation. It can load PNGs when using Bitmap::FromFile. It can load JPEGs, GIFs, and BMPs via FromFile or FromStream. So in short: on Vista, PNG files loaded via Bitmap::FromStream crash. #pragma comment(lib, "gdiplus.lib") #include <iostream> #include <objidl.h> #include <gdiplus.h> class FileStream : public IStream { public: FileStream(HANDLE hFile) { _refcount = 1; _hFile = hFile; } ~FileStream() { if (_hFile != INVALID_HANDLE_VALUE) { ::CloseHandle(_hFile); } } public: HRESULT static OpenFile(LPCWSTR pName, IStream ** ppStream, bool fWrite) { HANDLE hFile = ::CreateFileW(pName, fWrite ?

It crashes inside of lastResult = DllExports::GdipCreateBitmapFromStream(stream, &bitmap); from GdiPlusBitmap.h, which is a static inline wrapper over the flat API. Other than the reference counting, the only IStream methods it calls is stat (for file size), read, and seek. Call stack looks like: ntdll.dll!_DbgBreakPoint@0() + 0x1 bytes ntdll.dll!_RtlpBreakPointHeap@4() + 0x28 bytes ntdll.dll!_RtlpValidateHeapEntry@12() + 0x70a3c bytes ntdll.dll!_RtlDebugFreeHeap@12() + 0x9a bytes ntdll.dll!@RtlpFreeHeap@16() + 0x13cdd bytes ntdll.dll!_RtlFreeHeap@12() + 0x2e49 bytes kernel32.dll!_HeapFree@12() + 0x14 bytes ole32.dll!CRetailMalloc_Free() + 0x1c bytes ole32.dll!_CoTaskMemFree@4() + 0x13 bytes GdiPlus.dll!GpPngDecoder::GetImageInfo() + 0x68 bytes GdiPlus.dll!GpDecodedImage::InternalGetImageInfo() + 0x3c bytes GdiPlus.dll!GpDecodedImage::GetImageInfo() + 0x18 bytes GdiPlus.dll!CopyOnWriteBitmap::CopyOnWriteBitmap() + 0x49 bytes GdiPlus.dll!CopyOnWriteBitmap::Create() + 0x1d bytes GdiPlus.dll!GpBitmap::GpBitmap() + 0x2c bytes I was unable to find anybody else with the same problem, so I assume there's something wrong with my implementation...

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• UIWebView EXC_BAD_ACCESS crash

  - by HARDWARRIOR

  I'm experiencing crashes of an app that uses UIWebView. Usually it's when page is not fully loaded and UIWebView is sent stopLoading selector. Or when UIWebView fully loaded page. I've got EXC_BAD_ACCESS. Stack looks like this: #0 0x95bb7688 in objc_msgSend #1 0x30a671db in -[UIWebView webView:decidePolicyForNavigationAction:request:frame:decisionListener:] #2 0x3024a10d in __invoking___ #3 0x30249ff8 in -[NSInvocation invoke] #4 0x358ab160 in HandleDelegateSource #5 0x302452c1 in CFRunLoopRunSpecific #6 0x30244628 in CFRunLoopRunInMode #7 0x32044c31 in GSEventRunModal #8 0x32044cf6 in GSEventRun #9 0x309021ee in UIApplicationMain #10 0x0000239c in main at main.m:13 for me most strange thing here is webView:decidePolicyForNavigationAction:request:frame:decisionListener: selector sent to UIWebView, because there is no such selector in UIWebView documentation! Only for Cocoa (not cocoa touch) WebView. I suspect that there is something wrong with UIWebView or its delegate. But I can't set breakpoint to watch them. Please advise how I can get more info in this situation.

• UITableView : crash when adding a section footer view in empty section

  - by Supernico

  Hi everyone, This is the first time I ask a question here, but I have to say this site has been a tremendous help for me over the last couple months (iphone-dev-wise), and I thank you for that. However, I didn't find any solution for this problem I'm having: I have a UITableView with 2 sections, and no rows when the app is launched for the first time. The user can fill the sections later on as he wishes (the content is not relevant here). The UITableView looks good when filled with rows, but looks pretty ugly when there is none (the 2 header sections are stuck together with no white space in between). That is why I'd like to add a nice "No row" view in between when there is no row. I used viewForFooterInSection: - (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section { if(section == 0) { if([firstSectionArray count] == 0) return 44; else return 0; } return 0; } - (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{ if(section == 0) { UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 50, 44)]; label.backgroundColor = [UIColor clearColor]; label.textColor = [UIColor colorWithWhite:0.6 alpha:1.0]; label.textAlignment = UITextAlignmentCenter; label.lineBreakMode = UILineBreakModeWordWrap; label.numberOfLines = 0; label.text = @"No row"; return [label autorelease]; } return nil; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0) { return [firstSectionArray count]; } return [secondSectionArray count]; } This works great : the footer view appears only when there is no row in section 0. But my app crashes when I enter edit mode and delete the last row in section 0: Assertion failure in -[UIViewAnimation initWithView:indexPath:endRect:endAlpha:startFraction:endFraction:curve:animateFromCurrentPosition:shouldDeleteAfterAnimation:editing:] Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cell animation stop fraction must be greater than start fraction' This does not happen when there are several rows in section 0. It only happens when there is only one row left. Here's the code for edit mode: - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { // If row is deleted, remove it from the list. if (editingStyle == UITableViewCellEditingStyleDelete) { // Find the book at the deleted row, and remove from application delegate's array. if(indexPath.section == 0) { [firstSectionArray removeObjectAtIndex:indexPath.row]; } else { [secondSectionArray removeObjectAtIndex:indexPath.row]; } // Animate the deletion from the table. [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom]; [tableView reloadData]; } } Does anyone have any idea why this is happening? Thanks

• MATLAB Builder NE crash apppool on IIS 7.5

  - by Alkersan

  Im developing a web user interface for MATLAB functions with ASP.NET. Ive started with studying demos and stucked with such problem. I created a MyComponent.dll assembly with deploytool from MATLAB 2010a, target framework - 3.5. This component has one function GetKnot() which returns a figure. function df = getKnot() f = figure('Visible', 'off'); knot; df = webfigure(f); close(f); end Then I made simple webapp in visual studio 2008 sp1, with only one page Default.aspx. I added references to MWArray.dll, WebFiguresService.dll and MyComponent.dll. The codeBehind is: using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using MyComponent; using MathWorks.MATLAB.NET.WebFigures; namespace MATLAB_WebApplication { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var myComponentClass = new MyComponentClass(); var x = myComponentClass.getKnot(); //WebFigureControl1.WebFigure = new WebFigure(); } } } When I run this page on Visual Studio`s Development web server - everything is fine, figure works. But when I`m trying to deploy webfigure on my local iis 7.5 which runs on Win7 x32 - iis app pool crashes. There is an entry in System Event Log "A process serving application pool 'Classic .NET AppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3676'. The data field contains the error number 6D000780". This happens when MyComponent is instantiating. What I could forget when moved to IIS? Other examples, like magic square console application, runs perfect, and every matlab component instantiating, but not in IIS environment.

  I'm trying to migrate a MySQL DB to SQL Server using MS's SQL Server Import Export Wizard. It isn't going so well... The wizard either tells me that the MySQL syntax is invalid or crashes depending on its mood. Here is the query that it executes against MySQL before failing: select * from "_account" Anyway to change so either MySQL likes the quotes or the wizard doesn't use them?

• Crash: iPhone Threading with Blocks

  - by jtbandes

  I have some convenience methods set up for threading with blocks (using PLBlocks). Then in the main portion of my code, I call the method -fetchArrivalsForLocationIDs:callback:errback:, which runs some web API calls in the background. Here's the problem: when I comment out the 2 NSAutoreleasePool-related lines in JTBlockThreading.m, of course I get lots of Object 0x6b31280 of class __NSArrayM autoreleased with no pool in place - just leaking errors. However, if I uncomment them, the app frequently crashes on the [pool release]; line, sometimes saying malloc: *** error for object 0x6e3ae10: pointer being freed was not allocated" *** set a breakpoint in malloc_error_break to debug. I assume I've made a horrible mistake/assumption in threading somewhere, but can anyone figure out what exactly the problem is? // JTBlockThreading.h #import <Foundation/Foundation.h> #import <PLBlocks/Block.h> #define JT_BLOCKTHREAD_BACKGROUND [self invokeBlockInBackground:^{ #define JT_BLOCKTHREAD_MAIN [self invokeBlockOnMainThread:^{ #define JT_BLOCKTHREAD_END }]; #define JT_BLOCKTHREAD_BACKGROUND_END_WAIT } waitUntilDone:YES]; @interface NSObject (JTBlockThreading) - (void)invokeBlockInBackground:(void (^)())block; - (void)invokeBlockOnMainThread:(void (^)())block; - (void)invokeBlockOnMainThread:(void (^)())block waitUntilDone:(BOOL)wait; - (void)invokeBlock:(void (^)())block; @end // JTBlockThreading.m #import "JTBlockThreading.h" @implementation NSObject (JTBlockThreading) - (void)invokeBlockInBackground:(void (^)())block { [self performSelectorInBackground:@selector(invokeBlock:) withObject:[block copy]]; } - (void)invokeBlockOnMainThread:(void (^)())block { [self invokeBlockOnMainThread:block waitUntilDone:NO]; } - (void)invokeBlockOnMainThread:(void (^)())block waitUntilDone:(BOOL)wait { [self performSelectorOnMainThread:@selector(invokeBlock:) withObject:[block copy] waitUntilDone:wait]; } - (void)invokeBlock:(void (^)())block { //NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; block(); [block release]; //[pool release]; } @end - (void)fetchArrivalsForLocationIDs:(NSString *)locIDs callback:(JTWSCallback)callback errback:(JTWSErrback)errback { JT_PUSH_NETWORK(); JT_BLOCKTHREAD_BACKGROUND NSError *error = nil; // Create API call URL NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:@"%@/arrivals/appID/%@/locIDs/%@", TRIMET_BASE_URL, appID, locIDs]]; if (!url) { JT_BLOCKTHREAD_MAIN errback(@"That’s not a valid Stop ID!"); JT_POP_NETWORK(); JT_BLOCKTHREAD_END return; } // Call API NSData *data = [NSData dataWithContentsOfURL:url options:0 error:&error]; if (!data) { JT_BLOCKTHREAD_MAIN errback([NSString stringWithFormat: @"Had trouble downloading the arrival data! %@", [error localizedDescription]]); JT_POP_NETWORK(); JT_BLOCKTHREAD_END return; } CXMLDocument *doc = [[CXMLDocument alloc] initWithData:data options:0 error:&error]; if (!doc) { JT_BLOCKTHREAD_MAIN // TODO: further error description // (TouchXML doesn't provide information with the error) errback(@"Had trouble reading the arrival data!"); JT_POP_NETWORK(); JT_BLOCKTHREAD_END return; } NSArray *nodes = nil; CXMLElement *resultSet = [doc rootElement]; // Begin building the response model JTWSResponseArrivalData *response = [[[JTWSResponseArrivalData alloc] init] autorelease]; response.queryTime = [NSDate JT_dateWithTriMetWSTimestamp: [[resultSet attributeValueForName:@"queryTime"] longLongValue]]; if (!response.queryTime) { // TODO: further error check?

• UIImagePickerController Causes my app to crash!

  - by Flafla2

  In my app, a user can select an image, change the picture of a UIImageView to the new imge, and save the image to NSUserDefaults using NSKeyedArchiver. When the user selects the image the app immediately crashes! Here is my code - - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissModalViewControllerAnimated:YES]; if ([[NSUserDefaults standardUserDefaults] integerForKey:@"PictureKey"] == 1) { UIImage *previmage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [prevbutton setImage:previmage]; NSData *previmagedata = [NSKeyedArchiver archivedDataWithRootObject:previmage]; [[NSUserDefaults standardUserDefaults] setObject:previmagedata forKey:@"PrevImage"]; } else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"PictureKey"] == 2) { UIImage *nextimage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [nextbutton setImage:nextimage]; NSData *nextimagedata = [NSKeyedArchiver archivedDataWithRootObject:nextimage]; [[NSUserDefaults standardUserDefaults] setObject:nextimagedata forKey:@"NextImage"]; }else { UIImage *optionsimage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [moreoptionsbutton setImage:optionsimage]; NSData *optimagedata = [NSKeyedArchiver archivedDataWithRootObject:optionsimage]; [[NSUserDefaults standardUserDefaults] setObject:optimagedata forKey:@"OptionsImage"]; } } Thanks in advance!

• AVAudioPlayer crash after playing from an AVAudioRecorder

  I've got a button the user tap to start recording and tap again to stop. When it stop I want the recorded voice 'echo' back so the user can hear what was recorded. This works fine the first time.

• RegexKitLite Runtime Crash

  - by Hasan Can Saral

  I'm overlaying the mapview and using RegexKitLite. I couldn't make it work. I've downloaded .m and .h files and added to the project. Also I tried, adding libicucore.dylib or libicucore.A.dlib or adding -licucore to other compiler flags field. Still getting the error: 2012-04-01 19:38:04.633 sennerdeysen[907:15803] -[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00 2012-04-01 19:38:04.634 sennerdeysen[907:15803] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00' Any idea? Latest Xcode but the sdk is 4.3 Without ARC or anything else that iOS 5.0 SDK provides.
