  • Some questions about slugs in ASP.NET MVC content system

    - by mare
    In my application I'm currently using forms which allow to enter Title and Slug fields. Now I've been struggling with the slugs thing for a while because I can never decide once and for all how to handle them. 1) Make Title and Slug indenpendent Should I allow users to enter both Title and Slug separetely? This is what I had first. I also had an option that if user did not enter the Slug it was derived from the Title. If both were enter, the Slug field took precedence. 2) Derive Slug from Title, when content is inserted that's it for the Slug, no more changes Then, I switched to only Title field and derive Slug from title. While doing it I found out that now I have to change all the forms that allowed user to enter a slug. This way of doing it also prevents users to change Slugs - they can change the Title but it has no effect on the Slug. You can think of it like Slug is uniqued ID. 3) Now I'm thinking again of allowing users to change slug Though I don't think it is all that useful. How many times does the content that someone already added, spent time on writing it, even require a change of either Title or slug? I don't think it is that many times. The biggest problem with the 3rd option is that If I use Slugs as IDs, I need to update the reference all over the place when Slug changes. Or maintain a table that would contain somekind of Slug history. What are you thoughts on these, I hope, valid questions?

  • GNU Make: How to call $(wildcard) within $(eval)

    - by bengineerd
    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I can't seem to get the wildcard function to work within an eval. The basic code I'm having issues with looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $(join $(SRC_DIR), $(1)/) $(1)_SRC_FILES = $(wildcard $$($(1)_SRC_DIR)*.c) endef $(eval $(call PROGRAM_template, $(PROG_NAME))) all: @echo $(test_SRC_DIR) @echo $(test_SRC_FILES) @echo $(wildcard $(wildcard $(test_SRC_DIR)*.c) When I run make with this, the output is ./src/test [correct list of all .c files in ./src/test/] Basically, the wildcard call within PROGRAM_template is not being eval'd as I expect it. The call results in an empty list. The join call is being eval'd correctly though. So, what am I doing wrong? My guess is that $$($(1)_SRC_DIR) is not correct, but I can't figure out the right way to do it. EDIT Once this was solved, it didn't take long for me to hit another issue with eval. I posted it as a new question at http://stackoverflow.com/questions/2428506/workaround-for-gnu-make-3-80-eval-bug

  • In Python epoll can I avoid the errno.EWOULDBLOCK, errno.EAGAIN ?

    - by davyzhang
    I wrote a epoll wrapper in python, It works fine but recently I found the performance is not not ideal for large package sending. I look down into the code and found there's actually a LOT of error Traceback (most recent call last): File "/Users/dawn/Documents/workspace/work/dev/server/sandbox/single_point/tcp_epoll.py", line 231, in send_now num_bytes = self.sock.send(self.response) error: [Errno 35] Resource temporarily unavailable and previously silent it as the document said, so my sending function was done this way: def send_now(self): '''send message at once''' st = time.time() times = 0 while self.response != '': try: num_bytes = self.sock.send(self.response) l.info('msg wrote %s %d : %r size %r',self.ip,self.port,self.response[:num_bytes],num_bytes) self.response = self.response[num_bytes:] except socket.error,e: if e[0] in (errno.EWOULDBLOCK,errno.EAGAIN): #here I printed it, but I silent it in normal days #print 'would block, again %r',tb.format_exc() break else: l.warning('%r %r socket error %r',self.ip,self.port,tb.format_exc()) #must break or cause dead loop break except: #other exceptions l.warning('%r %r msg write error %r',self.ip,self.port,tb.format_exc()) break times += 1 et = time.time() I googled it, and says it caused by temporarily network buffer run out So how can I manually and efficiently detect this error instead it goes to exception phase? Because it cause to much time to rasie/handle the exception.

  • How can I encrypt CoreData contents on an iPhone

    - by James A. Rosen
    I have some information I'd like to store statically encrypted on an iPhone application. I'm new to iPhone development, some I'm not terribly familiar with CoreData and how it integrates with the views. I have the data as JSON, though I can easily put it into a SQLITE3 database or any other backing data format. I'll take whatever is easiest (a) to encrypt and (b) to integrate with the iPhone view layer. The user will need to enter the password to decrypt the data each time the app is launched. The purpose of the encryption is to keep the data from being accessible if the user loses the phone. For speed reasons, I would prefer to encrypt and decrypt the entire file at once rather than encrypting each individual field in each row of the database. Note: this isn't the same idea as Question 929744, in which the purpose is to keep the user from messing with or seeing the data. The data should be perfectly transparent when in use. Also note: I'm willing to use SQLCipher to store the data, but would prefer to use things that already exist on the iPhone/CoreData framework rather than go through the lengthy build/integration process involved.

  • How do I break down MySQL query results into categories, each with a specific number of rows?

    - by Mel
    Hello, Problem: I want to list n number of games from each genre (order not important) The following MySQL query resides inside a ColdFusion function. It is meant to list all games under a platform (for example, list all PS3 games; list all Xbox 360 games; etc...). The variable for PlatformID is passed through the URL. I have 9 genres, and I would like to list 10 games from each genre. SELECT games.GameID AS GameID, games.GameReleaseDate AS rDate, titles.TitleName AS tName, titles.TitleShortDescription AS sDesc, genres.GenreName AS gName, platforms.PlatformID, platforms.PlatformName AS pName, platforms.PlatformAbbreviation AS pAbbr FROM (((games join titles on((games.TitleID = titles.TitleID))) join genres on((genres.GenreID = games.GenreID))) join platforms on((platforms.PlatformID = games.PlatformID))) WHERE (games.PlatformID = '#ARGUMENTS.PlatformID#') ORDER BY GenreName ASC, GameReleaseDate DESC Once the query results come back I group them in ColdFusion as follows: <cfoutput query="ListGames" group="gName"> (first loop which lists genres) #ListGames.gName# <cfoutput> (nested loop which lists games) #ListGames.tName# </cfoutput> </cfoutput> The problem is that I only want 10 games from each genre to be listed. If I place a "limit" of 50 in the SQL, I will get ~ 50 games of the same genre (depending on how much games of that genre there are). The second issue is I don't want the overload of querying the database for all games when each person will only look at a few. What is the correct way to do this? Many thanks!

  • iPhone: CATiledLayer/UIScrollView wont scroll after zooming and only zooms to anchor point

    - by Brodie4598
    Here is the problem... I am using CA Tiled Layer to display a large jpg. The view loads okay, and when I go to scroll around, it works fine. However, as soon as I zoom in or out once, it scrolls to the top left (to the anchor point) and will not scroll at all. The zooming works fine, but I just cannot scroll. Here is my code: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

  • android keylistener losing key taps

    - by miannelle
    I am using a keylistener to get key taps. The problem is that once you tap the delete key, the next key tap is not registering. The key tap after that keeps working. If I tap 2 deletes in a row, they work, just no other keys. They just disappear. I put in a log test before the "if (keycode" section and it shows nothing after the first delete is pressed, unless it is another delete. I am using the following code (Thanks Shawn).: itemPrice.setKeyListener(new CalculatorKeyListener()); itemPrice.setRawInputType(Configuration.KEYBOARD_12KEY); class CalculatorKeyListener extends NumberKeyListener { public int getInputType() { return InputType.TYPE_CLASS_NUMBER; } @Override public boolean onKeyDown(View view, Editable content, int keyCode, KeyEvent event) { if (keyCode >= KeyEvent.KEYCODE_0 && keyCode <= KeyEvent.KEYCODE_9) { digitPressed(keyCode - KeyEvent.KEYCODE_0); } else if (keyCode == KeyEvent.KEYCODE_DEL) { deletePressed(); } return true; } @Override protected char[] getAcceptedChars() { return new char[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; } } With this problem the keylistener provides no value to me. There must be something that I am missing. Thanks,

  • PHP's SimpleXML: How to use colons in names

  • Unable to fetch initial output of "defrag" commad in Windows Server 2008 R2 in WOW64 environment.

    - by Ganesh
    Hi All, [Application & code back ground] I have an MFC application which is executing on Windows Server 2008 R2 in WOW64 environment. In which on user input it defragments the selected drive on the disk. I initiated the process(.i.e. cmd /c defrag –v c:) of defragmentation using the CreateProcess() API, along with this to display output of the process on the main screen I created the pipe using CreatePipe() API. I used PeekNamedPipe() & ReadFile() API to get the output and display. [Problem Area] When the process is launched I am not getting the initial output as below: Microsoft Disk fragmenter Copyright © 2007 Microsoft Crop. Invoking defragmentation on (C:)…. I constantly monitor the output of the process while it is under progress but not able to get any thing as output in the pipe. It seem the process is not doing any thing and appears as if the application is not responding. But after certain period of time, once the process is about to completed I get result along with the initial data. [Sample code] //Pipe created if(0 == ::CreatePipe(&l_hStdOutRead, &l_hStdOutWrite, &l_SecurityAttribute, (DWORD)NULL)) { //Error code } //Process created/launched if (0 == ::CreateProcess(NULL, (LPTSTR)f_csProcessName, &l_stSecurityAttributes, NULL, TRUE, CREATE_NO_WINDOW, NULL,NULL, &l_StartupInfo, &l_CmdPI)) { //Error code } //Read output if (0 == ::PeekNamedPipe(m_hStdOutRead, l_cArrPeekBuffer, (DWORD)NULL, (LPDWORD)NULL, &l_dwAvailable, (LPDWORD)NULL)) { //Return to read again } if (MPLUSFALSE == ::ReadFile(m_hStdOutRead, l_cArrOutput, min(BUFFER_SIZE - 2, l_dwAvailable), &l_dwRead, NULL) || !l_dwRead) { //error code } //Display data. If any one is aware of similar problem or worked on the similar issue please let me know the solution. Thanks in Advance, Ganesh

  • Use of qsrand, random method that is not random

    - by Andy M
    Hey everyone, I'm having a strange problem here, and I can't manage to find a good explanation to it, so I thought of asking you guys : Consider the following method : int MathUtility::randomize(int Min, int Max) { qsrand(QTime::currentTime().msec()); if (Min > Max) { int Temp = Min; Min = Max; Max = Temp; } return ((rand()%(Max-Min+1))+Min); } I won't explain you gurus what this method actually does, I'll instead explain my problem : I realised that when I call this method in a loop, sometimes, I get the same random number over and over again... For example, this snippet... for(int i=0; i<10; ++i) { int Index = MathUtility::randomize(0, 1000); qDebug() << Index; } ...will produce something like : 567 567 567 567...etc... I realised too, that if I don't call qsrand everytime, but only once during my application's lifetime, it's working perfectly... My question : Why ?

  • Parallel port with C#

    Hello, I am trying to send data to LPT1 port with a C# program, unfortunately with no success.. I am using windows 7 x64. I tried both x86 and x64 (inpoutx64.dll) dll's.. With the x64 dll when I send: Output(888, 255); It just continues the program as everything went ok, but i can't see anything on my multimeter (only the static 0.02V).. I also tried the following with C++: int main () { int val = 0; printf("Enter a value\n"); scanf("%d", &val); _outp(0x378, val); getchar(); _outp(0x378, 0); return 0; } But it throws an exception: Unhandled exception at 0x01281428 in ppac.exe: 0xC0000096: Privileged instruction. I remember once I made something like this work on xp, I hope it's possible on win7 too.. Please help me with this. Thanks.

  • Fade out when user leaves page — jquery

  • Spikes in Socket Performance

    - by Harun Prasad
    We are facing random spikes in high throughput transaction processing system using sockets for IPC. Below is the setup used for the run: The client opens and closes new connection for every transaction, and there are 4 exchanges between the server and the client. We have disabled the TIME_WAIT, by setting the socket linger (SO_LINGER) option via getsockopt as we thought that the spikes were caused due to the sockets waiting in TIME_WAIT. There is no processing done for the transaction. Only messages are passed. OS used Centos 5.4 The average round trip time is around 3 milli seconds, but some times the round trip time ranges from 100 milli seconds to couple of seconds. Steps used for Execution and Measurement and output Starting the server $ python sockServerLinger.py /dev/null & Starting the client to post 1 million transactions to the server. And logs the time for a transaction in the client.log file. $ python sockClient.py 1000000 client.log Once the execution finishes the following command will show the execution time greater than 100 milliseconds in the format <line_number>:<execution_time>. $ grep -n "0.[1-9]" client.log | less Below is the example code for Server and Client. Server # File: sockServerLinger.py import socket, traceback,time import struct host = '' port = 9999 l_onoff = 1 l_linger = 0 lingeropt = struct.pack('ii', l_onoff, l_linger) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.setsockopt(socket.SOL_SOCKET, socket.SO_LINGER, lingeropt) s.bind((host, port)) s.listen(1) while 1: try: clientsock, clientaddr = s.accept() print "Got connection from", clientsock.getpeername() data = clientsock.recv(1024*1024*10) #print "asdasd",data numsent=clientsock.send(data) data1 = clientsock.recv(1024*1024*10) numsent=clientsock.send(data) ret = 1 while(ret>0): data1 = clientsock.recv(1024*1024*10) ret = len(data) clientsock.close() except KeyboardInterrupt: raise except: print traceback.print_exc() continue Client # File: sockClient.py import socket, traceback,sys import time i = 0 while 1: try: st = time.time() s = socket.socket(socket.AF_INET,socket.SOCK_STREAM) while (s.connect_ex(('127.0.0.1',9999)) != 0): continue numsent=s.send("asd"*1000) response = s.recv(6000) numsent=s.send("asd"*1000) response = s.recv(6000) i+=1 if i == int(sys.argv[1]): break except KeyboardInterrupt: raise except: print "in exec:::::::::::::",traceback.print_exc() continue print time.time() -st

  • Copy Selective Data from Database to Invoice, Based on Certain Criteria

    - by Scott
    For starters, here is an example of a microsoft excel database I am working with: Month/Address/Name/Description/Amount January/123 Street/Fred/Painting/100 January/456 Avenue/Scott/Flooring/400 January/789 Road/Scott/Plumbing/100 February/123 Street/Fred/Flooring/600 February/246 Lane/Fred/Electrical/300 March/789 Road/Scott/Drywall/150 What I want to be able to do is selectively copy info from this databse to invoices (also excel). The invoice has three columns: Address/Description/Amount. I want to be able to automatically fill the invoices in as the database is filled in (either automatically, or if I have to actually manually run the macro to do it, that might be fine). Each name (Scott, Fred, etc.) will have their own set of 12 invoices for the year. So, e.g., I want to be able to produce a January invoice for all work done for Scott in January, showing the address, the description and the amount, line by line. So every time work on Scott's address(es) is done, the database is filled in, and i want it to "send" that information to the invoice on the next available line, filling in only the Address/Description/Amount columns from the database. Fred's invoice should fill in as any work is done on Fred's addresses. And once the month changes, the next invoice should start filling in. So first I need to filter the data by the month and the name (and there is actually one more column to filter by, but let's keep this example simpler). Then I need to list the remaining data on the invoice, but only certain cells from the rows that are now left. Help anyone?

  • Do I really need an ORM?

    - by alchemical
    We're about to begin development on a mid-size ASP.Net MVC 2 web site. For a typical page, we grab data and throw it up on the web page, i.e. there is not much pre-processing of the data before it is sent to the UI. We're now making the decision whether or not to use an ORM and if yes, which one. We had been looking at EF2 AKA EF4 (ASP.Net Entity Framework in VS 2010) as one possibility. However, I'm thinking a simple solution in this case may be just to use datatables. The reason being that we don't plan to move the data around or process it a lot once we fetch it, so I'm not sure there is that much value in having strongly-typed objects as DTOs. Also, this way we avoid mapping altogether, thereby I think simplifying the code and allowing for faster development. I should mention budget is an issue on this project, as well as speed of execution. We are striving for simplicity anywhere we can, both to keep the budget smaller, the schedule shorter, and performance fast. We haven't fully decided this yet, but are currently leaning towards no ORM. Will we be OK with the no ORM approach or is an ORM worth it?

  • Programmatic skins in Flex

    - by Flexer
    Hi, I am having 2 problems creating programmatic skin for Canvas. First problem: I would like to have background with rounded corners and I am using GraphicsUtil.drawRoundRectComplex in order to have round corners for only the upper two corners. The problem is that drawRoundRectComplex takes for each corner one single parameter - the corner radius. However my scaleX and scaleY factors are different and in fact the corners are not properly rounded because I either can set the radius using scaleX or scaleY. Graphics.drawRoundRect is better because it takes two parameters for the corners - elipse width and height and then you could apply both scale factors but it doesn't allow me to specify different radius for different corners. I am looking for an idea how to use GraphicsUtil.drawRoundRectComplex when scaleX and scaleY are different. Second problem: Even though I set my programmatic skin through style - < the skin's updateDisplayList gets executed only once and after that somehow "backgroundImage" style gets "undefined" and my programmatic skin is not associated anymore to the Canvas instance. As a workaround I am setting on each resize event "backgroundImage" style again but this is ugly. What could cause such "silent" resetting of the "backgroundImage" style to undefined? Thanks!

  • Reading a Serial Port - Ignore portion of data written to serial port for certain time

    - by farmerjoe
    I would like to read data coming and Arduino on a serial port on intervals. So essentially something like Take a reading Wait Take a reading Wait Take ... etc. The problem I am facing is that the port will buffer its information so as soon as I call a wait function the data on the serial port will start buffering. Once the wait function finishes I try and read the data again but I am reading from the beginning of the buffer and the data is not current anymore, but instead is the reading taken at roughly the time the wait function began. My question is whether there is a way that I am unaware of to ignore the portion of data read in during that wait period and only read what is currently being delivered on the serial port? I have this something analogous to this so far: import serial s = serial.Serial(path_to_my_serial_port,9600) while True: print s.readline() time.sleep(.5) For explanation purposes I have the Arduino outputting the time since it began its loop. By the python code, the time of each call should be a half second apart. By the serial output the time is incrementing in less than a millisecond. These values do not change regardless of the sleep timing. Sample output: 504 504 504 504 505 505 505 ... As an idea of my end goal, I would like to measure the value of the port, wait a time delay, see what the value is then, wait again, see what the value is then, wait again. I am currently using Python for this but am open to other languages.

  • Change DIV contents on SELECT change

    - by Ian Batten
    I'm looking for a method of how to change the contents of a div when an option on a select dropdown is selected. I came across the following: <script type="text/javascript" src="jquery.js"></script> <!-- the select --> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> <!-- the jQuery --> <script type="text/javascript" src="path/to/jquery.js"></script> <script type="text/javascript"> $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); </script> This worked fine on it's own, but I want to use it with the following script: http://www.dynamicdrive.com/dynamicindex1/chainedmenu/index.htm When using it alongside this chainedmenu script, it just loads all of the DIV box contents at once, rather than each div option when a SELECT option is chosen. Any ideas on what I can use alongside this chainedmenu script to get different DIV contents to show for different SELECT options? Thanks in advance, Ian EDIT Here is a test page: http://freeflamingo.com/t/new.html

  • Only first UIView added view addSubview shows correct orientation

    - by Brian Underwood
    I've got three ViewControllers set up to handle three views. The problem that I'm having is that in the simulator the orientation is LandscapeRight (which is what I want), and the first view shows up correctly in that landscape view, but when I move onto the second and third views, they show up rotated 90 degrees counter-clockwise with the upper-left corner of the view in the lower left corner of the phone's screen. I've been trying to debug this for a few days and the closest that I've gotten to a clue is tracing it the following way: The following is in my app delegate's applicationDidFinishLaunching: NSLog(@"1"); [window addSubview:welcomeController.view]; NSLog(@"2"); [window addSubview:goalController.view]; NSLog(@"3"); [window addSubview:planningController.view]; NSLog(@"4"); [window bringSubviewToFront:welcomeController.view]; NSLog(@"5"); Each of my ViewControllers implement something similar to the following (the only change being the controller's name switched out in the string passed to NSLog): - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations NSLog(@"called for WelcomeController"); return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } With that, I get the following output on the Console: a called for WelcomeController called for WelcomeController called for WelcomeController called for WelcomeController 2 called for GoalController 3 called for PlanningController 4 5 I find it interesting that shouldAutorotateToInterfaceOrientation is called 4 times for the first view that's added, while the other two only get called once. I expect that this is probably because it's got to do some setup at first (and I believe that the simulator starts off in portrait mode, so it's might be calling it while doing the rotation), but I find the correlation a bit suspicious. I've switched the order around so that the addSubview is called for the goalController first and the welcomeController second. In this case, it's the goalController which displays in the correct landscape orientation (it's normally the welcome controller). This would seem to eliminate my XIB files and the ViewControllers themselves. I'm not sure why the first view where addSubview is called is special. I also tried using insertSubview at index 0 with the same results.

  • Java random values and duplicates

    - by f-Prime
    I have an array (cards) of 52 cards (13x4), and another array (cardsOut) of 25 cards (5x5). I want to copy elements from the 52 cards into the 25 card array by random. Also, I dont want any duplicates in the 5x5 array. So here's what I have: double row=Math.random() *13; double column=Math.random() *4; boolean[][] duplicates=new boolean[13][4]; pokerGame[][] cardsOut = new pokerGame[5][5]; for (int i=0;i<5;i++) for (int j=0;j<5;j++){ if(duplicates[(int)row][(int)column]==false){ cardsOut[i][j]=cards[(int)row][(int)column]; duplicates[(int)row][(int)column]=true; } } 2 problems in this code. First, the random values for row and column are only generated once, so the same value is copied into the 5x5 array every time. Since the same values are being copied every time, I'm not sure if my duplicate checker is very effective, or if it works at all. How do I fix this?

  • App crashes only after second execution only in Release configuration

    - by denbec
    Hey all, i know this is probably not an easy question to answer, as it's hard to describe on my hand. I have an app that runs without problems on the device in Debug Configuration (also multiple times). Once I put it into Release Configuration (which I need before publishing?), the app starts without problems and I can proceed to the next page, where I show an core-plot graph. BUT only if I run it from xcode. As soon as I end the App and start it again, it opens without problems, but on the next page, it crashes. Now I don't have anything to debug other than the crash report: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0xcf10000a Crashed Thread: 0 Thread 0 Crashed: 0 libobjc.A.dylib 0x000026f2 objc_msgSend + 14 1 StandbyCheck 0x0001fbea -[CPXYTheme newGraph] (CPXYTheme.m:36) 2 StandbyCheck 0x00007c06 -[SCGraphCell initWithStyle:reuseIdentifier:] (SCGraphCell.m:28) 3 StandbyCheck 0x00076b4a -[TTTableViewDataSource tableView:cellForRowAtIndexPath:] (TTTableViewDataSource.m:128) 4 UIKit 0x0007797a -[UITableView(UITableViewInternal) _createPreparedCellForGlobalRow:withIndexPath:] + 514 5 UIKit 0x000776b0 -[UITableView(UITableViewInternal) _createPreparedCellForGlobalRow:] + 28 6 UIKit 0x00037e78 -[UITableView(_UITableViewPrivate) _updateVisibleCellsNow] + 940 7 UIKit 0x000367d4 -[UITableView layoutSubviews] + 176 8 StandbyCheck 0x000734b8 -[TTTableView layoutSubviews] (TTTableView.m:226) [...] Now, can someone point in any direction? What are the differences in Debug/Release Modes? How could I possibly debug this failure? I've been searching for hours now, please help me :( Thanks, Dennis

  • How to best handle exception to repeating calendar events

    - by blcArmadillo
    I'm working on a project that will require me to implement a calendar. I'm trying to come up with a system that is very flexible: can handle repeating events, exceptions to repeats, etc. I've looked at the schema for applications like iCal, Lotus Notes, and Mozilla to get an idea of how to go about implementing such a system. Currently I'm having trouble deciding what is the best way to handle exceptions to repeating events. I've used databases quite a bit but don't have a ton of experience with really optimizing everything so I'm not sure which method of the two I'm considering would be optimal in terms of overall performance and ability to query/search: Breaking the repeating event. So taking the changing the ending date on the current row for the repeating event, inserting a new row with the exception, and adding another row continuing the old sequence. Simply adding an exception. So adding a new row with some field that indicates it as an override. So here is why I can't decide. Method one will result in a lot more rows since each edit requires 2 extra rows as apposed to only one row by the second method. On the other hand I think the query to find an event would be much simper, and thus possibly faster(?) using the first method. The second method seems like it will require more calculating on the application server since once you get the data you'll have to remove the intersection of the two rows. I know databases are often the bottleneck for websites and while I'm sure a lot of you are thinking either is fine because your project will probably never get large enough for the difference in efficiency to really matter, I'd still like to implement the best solution. So what method would you guys pick, or would you do something completely different? Also, as a side note I'll be using MySQL and PHP. If there is another technology that you think would be better suited for this, especially in the database area, please mention it. Thanks for the advice.

  • SQL Server 2005 and 'General network error'

    - by Mariusz
    I know there is a lot of information in the Internet about solving this problem, but it didn't help me. My Delphi application uses dbExpress controls to access the database and execute SQL queries. Once every couple of days, however, it stops working because the database connection fails. This happens on several different computers with different versions of Windows. MSSQL Server 2005 (version 9.0.4035) is installed on each of them. The above mentioned application executes queries every couple of seconds, and they are mainly insert commands. Every couple of days I get a series of exceptions like the following one: [DBNETLIB][ConnectionOpen (PreLoginHandshake()).]General network error. Check your network documentation. And then the SQL server becomes inaccessible until I restart it manually. The information I found in the Internet say that I should install some service packs, change some registry entries etc., but believe me, none of these helps and I don't know what else to do now. Could you please help me solve this problem? Any clues or ideas? I can give you some more information about the server or the application if necessary. Thank you very much in advance.
