  • Very very weird problem with UIImageView property - I can access it then I can't, and it's not nil.

    - by just_another_coder
    Very very weird problem with UIImageView property on iPad application @interface MyViewController : UIViewController { IBOutlet UIImageView* coverImage; } @property(nonatomic, retain) IBOutlet UIImageView* coverImage; … more code @implementation MyViewController @synthesize coverImage; … more code - (void)viewDidLoad { [super viewDidLoad]; NSString* imageName = @"my_image.png"; UIImage* tempImage = [UIImage imageNamed:imageName]; [self.coverImage setImage:tempImage]; } The above code WILL display the image. In another part of code: -(IBAction) stopButtonPressed:(id)sender { [self.coverImage setHidden:YES]; NSLog(@"coverImage desc: %@", [coverImage description]); } The image will NOT disappear. I know the reference to the image isn't nil, because it gives me this output: 2010-05-29 17:37:40.706 MyApp[95360:207] coverImage desc: UIImageView: 0x5128420; frame = (0 0; 1024 768); autoresize = RM+BM; userInteractionEnabled = NO; layer = CALayer: 0x512bed0 In addition, if I move the code in viewDidLoad to another part of the class, and try to execute it from there, it fails to show the image at all.

  • Breadcrumbs in Fusebox 4/5

    - by Jordan Reiter
    I'm wondering if anyone has come up with a clean way to generate a breadcrumbs trail in Fusebox. Specifically, is there a way of keeping track of "where you are" and having that somehow generate the breadcrumbs for you? So, for example, if you're executing /index.cfm?fuseaction=Widgets.ViewWidget&widget=1 and the circuit structure is something like /foo/bar/widgets/ then somehow the system automatically creates an array like: [ { title: 'Foo', url: '#self#?fuseaction=Foo.Main' }, { title: 'Bar', url: '#self#?fuseaction=Bar.Main' }, { title: 'Widgets', url: '#self#?fuseaction=Widgets.Main' }, { title: 'Awesome Widget', url: '' } ] Which can then be rendered as Foo Bar Widgets Awesome Widget Right now it seems the only way to really do this is to create the structure for each fuseaction in a fuse of some kind (either the display fuse or a fuse dedicated to creating the crumbtrail).

  • Struct size containing vector<T> different sizes between DLL and EXE..

    - by Michael Peddicord
    I have this situation where an EXE program imports a DLL for a single function call. It works by passing in a custom structure and returning a different custom structure. Up till now it's worked fine until I wanted one of the structs data members to be a vector < MyStruct When I do a sizeof(vector< MyStruct ) in my program I get a size of 20 but when I do it from inside the DLL I get a size of 24. This size inconsistency is causing a ESP pointer error. Can anyone tell me why a Vector < MyStruct would be a different size in the DLL than in the program? I have reverified that my structs in both the DLL and the Program are identical. I would appreciate any help on the subject. Thank you.

  • Javascript obfuscation help

The code is: <a id="suggest" href="#" ajaxify="/ajax/social_graph/invite_dialog.php?class=FanManager&amp;node_id=108463912505356" class=" profile_action actionspro_a" rel="dialog-post">Suggest to Friends</a> And the obfuscation is: \x3c\x61\x20\x69\x64\x3d\x22\x73\x75\x67\x67\x65\x73\x74\x22\x20\x68\x72\x65\x66\x3d\x22\x23\x22\x20\x61\x6a\x61\x78\x69\x66\x79\x3d\x22\x2f\x61\x6a\x61\x78\x2f\x73\x6f\x63\x69\x61\x6c\x5f\x67\x72\x61\x70\x68\x2f\x69\x6e\x76\x69\x74\x65\x5f\x64\x69\x61\x6c\x6f\x67\x2e\x70\x68\x70\x3f\x63\x6c\x61\x73\x73\x3d\x46\x61\x6e\x4d\x61\x6e\x61\x67\x65\x72\x26\x61\x6d\x70\x3b\x6e\x6f\x64\x65\x5f\x69\x64\x3d\x31\x30\x38\x34\x36\x33\x39\x31\x32\x35\x30\x35\x33\x35\x36\x22\x20\x63\x6c\x61\x73\x73\x3d\x22\x20\x70\x72\x6f\x66\x69\x6c\x65\x5f\x61\x63\x74\x69\x6f\x6e\x20\x61\x63\x74\x69\x6f\x6e\x73\x70\x72\x6f\x5f\x61\x22\x20\x72\x65\x6c\x3d\x22\x64\x69\x61\x6c\x6f\x67\x2d\x70\x6f\x73\x74\x22\x3e\x53\x75\x67\x67\x65\x73\x74\x20\x74\x6f\x20\x46\x72\x69\x65\x6e\x64\x73\x3c\x2f\x61\x3e","\x73\x75\x67\x67\x65\x73\x74 Now I used unescape on the above obfuscated code to read it. What I want to know is what exactly was used to obfuscate the code like that? Basically, I need to customize the readable code to the same obfuscation. Any help would be greatly appreciated.

  • VS2005 SQL Syntax highlighting is incorrect for nested comments?

    - by MattH
    I'm working with VS2005, and SSMS 2005. SQL Server allows nested comments as follows: /* Comment 1 /* Comment 2 */ Some commented out code here */ This code runs fine. However if putting the above into a .sql file in VS2005, it incorrectly shows the commented out code as 'active', (its not green). It seems that StackOverflow has highlighted the code in the same way. Is this a bug in VS2005? Or does SSMS handle nested comments differently compared to the ANSI SQL standards? Can someone clarify this discrepancy, and if it appears to be a bug, if there a way to fix the syntax highlighting?

  • Load different views depending on the category of data on tap of tableview cell iPhone sdk

    - by neha
    Hi all, In my aplication, I want a tableview with different cell structure depending upon the category of data that's getting loaded in it [I have different categories like video, editorial etc with different structure of data like video has a single label, editorial has 3 labels etc]. I can load different nib files based on the data coming from xml parser. Now when the cell is tapped, I want to show its detailed view on a new viewController. So my question is is it possible to use only 1 viewController show different fields depending upon the category of data in the cell. Or do I need to create different viewControllers for each of the categories?

  • Treat a void function as a value

    - by Brendan Long
    I'm writing some terrible, terrible code, and I need a way to put a free() in the middle of a statement. The actual code is: int main(){ return printf("%s", isPalindrome(fgets(malloc(1000), 1000, stdin))?"Yes!\n":"No!\n") >= 0; // leak 1000 bytes of memory } I was using alloca(), but I can't be sure that will actually work on my target computer. My problem is that free returns void, so my code has this error message: error: void value not ignored as it ought to be The obvious idea I had was: int myfree(char *p){ free(p); return 0; } Which is nice in that it makes the code even more unreadable, but I'd prefer not to add another function. I also briefly tried treating free() as a function pointer, but I don't know if that would work, and I don't know enough about C to do it properly. Note: I know this is a terrible idea. Don't try this at home kids.

  • Most frustrating programming style you've encountered

    - by JaredPar
    When it comes to coding style I'm a pretty relaxed programmer. I'm not firmly dug into a particular coding style. I'd prefer a consistent overall style in a large code base but I'm not going to sweat every little detail of how the code is formatted. Still there are some coding styles that drive me crazy. No matter what I can't look at examples of these styles without reaching for a VIM buffer to "fix" the "problem". I can't help it. It's not even wrong, I just can't look at it for some reason. For instance the following comment style almost completely prevents me from actually being able to read the code. if (someConditional) // Comment goes here { other code } What's the most frustrating style you've encountered?

  • basic operations for modifying a source document with XSLT

    - by SpliFF
    All the tutorials and examples I've found of XSLT processing seem to assume your destination will be a significantly different format/structure to your source and that you know the structure of the source in advance. I'm struggling with finding out how to perform simple "in-place" modifications to a HTML document without knowing anything else about its existing structure. Could somebody show me a clear example that, given an arbitrary unknown HTML source will: 1.) delete the classname 'foo' from all divs 2.) delete a node if its empty (ie <p></p>) 3.) delete a <p> node if its first child is <br> 4.) add newattr="newvalue" to all H1 5.) replace 'heading' in text nodes with 'title' 6.) wrap all <u> tags in <b> tags (ie, <u>foo</u> -> <b><u>foo</u></b>) 7.) output the transformed document without changing anything else The above examples are the primary types of transform I wish to accomplish. Understanding how to do the above will go a long way towards helping me build more complex transforms. To help clarify/test the examples here is a sample source and output, however I must reiterate that I want to work with arbitrary samples without rewriting the XSLT for each source: <!doctype html> <html> <body> <h1>heading</h1> <p></p> <p><br>line</p> <div class="foo bar"><u>baz</u></div> <p>untouched</p> </body> </html> output: <!doctype html> <html> <body> <h1 newattr="newvalue">title</h1> <div class="bar"><b><u>baz</u></b></div> <p>untouched</p> </body> </html>

  • Compiling Enet in iphone xcode project

    - by EToreo
    Hello, I am trying to compile the Enet source code into my code framework for iPhone games. After modifying the header files I get it compiling and linking, but I absolutely must be compiling with the "Compile Source As" set to "Objective-C++" in my xcode project (because the framework code requires this). When I flip this switch in my test project, I get these errors: Undefined symbols: "_enet_list_clear", referenced from: _enet_host_connect in host.o ... Can anyone help get this linking with "Compile Source As" set to "Objective-C++"?

  • How to get colliding effect or bouncy when ball hits the track.

    - by Chandan Shetty SP
    I am using below formula to move the ball circular, where accelX and accelY are the values from accelerometer, it is working fine. But the problem in this code is mRadius (I fixed its value to 50), i need to change mRadius according to accelerometer values and also i need bouncing effect when it touches the track. Currently i am developing code by assuming only one ball is on the board. float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); Here is the snap of the game i want to develop: Updated: I am sending the updated code... mRadius = 5; mRange = NSMakeRange(0,60); -(void) updateBall: (UIAccelerationValue) accelX withY:(UIAccelerationValue)accelY { float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); //self.targetRect is rect of ball Object self.targetRect = CGRectMake(newX, newY, 8, 9); self.currentRect = self.targetRect; //http://books.google.co.in/books?id=WV9glgdrrrUC&pg=PA455#v=onepage&q=&f=false static NSDate *lastDrawTime; if(lastDrawTime!=nil) { NSTimeInterval secondsSinceLastDraw = -([lastDrawTime timeIntervalSinceNow]); ballXVelocity = ballXVelocity + (accelX * secondsSinceLastDraw) * [self isTouchedTrack:mRadius andRange:mRange]; ballYVelocity = ballYVelocity + -(accelY * secondsSinceLastDraw) * [self isTouchedTrack:mRadius andRange:mRange]; distXTravelled = distXTravelled + secondsSinceLastDraw * ballXVelocity * 50; distYTravelled = distYTravelled + secondsSinceLastDraw * ballYVelocity * 50; CGRect temp = self.targetRect; temp.origin.x += distXTravelled; temp.origin.y += distYTravelled; int radius = (temp.origin.x - cCentrePoint.x) / cos(degreesToRadians(degrees)); if( !NSLocationInRange(abs(radius),mRange)) { //Colided with the tracks...Need a better logic here ballXVelocity = -ballXVelocity; } else { // Need a better logic here self.targetRect = temp; } //NSLog(@"angle = %f",degrees); } [lastDrawTime release]; lastDrawTime = [ [NSDate alloc] init]; } In the above code i have initialized mRadius and mRange(indicate track) to some constant for testing, i am not getting the moving of the ball as i expected( bouncing effect when Collided with track ) with respect to accelerometer. Help me to recognize where i went wrong or send some code snippets or links which does the similar job. I am searching for better logic than my code, if you found share with me.

  • Need Help with Page Life Cycle(I think it is screwing me up)

    - by chobo2
    Hi I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db. This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists. This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason. if (IsPostBack == false) { // check if dummy variables exist in db- If true just generate tables with values in db. If not generate them. } else { // grab the values from the database // generate tables with the values } btn click event { go through all rows in table(foreach loop) update each column in the database with cells in each row. while in foreach loop. //done } So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user. Does not work if (IsPostBack == false) { // same code as above } // if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens. btn click event { // same code } Fails also. if (IsPostBack == false) { // same code as above } else { // same code as above but moved into its own method. gernerateTable(); } btn click event { // update all rows // once done clear the Tables rows // call generateTable() } This last one does nothing as for some reason it does not update anything. I don't understand why. So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.

EmployeeMaster (DB table structure) EmployeeID (PK) | EmployeeName | City MonthMaster (DB table structure) Month | Year | EmployeeID (FK) | PrenentDays | BasicSalary Now my question is, I want to store data in file system rather than storing data in SQL or ORACLE. I want my data in file system storage for Insert, Edit and Delete opration with keeping relation with objects too. I am a C# developer, Could anybody have thoughts or idea on it. (To store data in file system with keeping relations between them) Thanks in advance. Any ideas on it?

  • how to tackle a custom forms database

    - by Neil Hickman
    I'm currently researching a project for the place that I work in. We are trying to create a system that will allow forms to be set up dynamically from a database. My question is what database structure would best suit something like this? I currently have a structure of: forms_form forms_formfields forms_formdata I don't think this is the most appropriate layout for this. Basically to make is make sense I need to be able to make a form within the database that can have infinite fields all customized and have the data when submitted stored in the database.

  • IEnumerable not null but calling Count() results in Exception

    - by Draak
    I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled. Here's the code. The question is below. Dim certs = From p In persons _ Select New Certificate( _ p.Value, _ New CertificateData.Seminar(thisEvent.Seminar.Name, _ thisEvent.StartDate.Value, _ thisEvent.EndDate.Value, _ thisEvent.Venue.City, _ thisEvent.Venue.State, _ New CertificateData.Instructor( _ staffMember.Name, _ staffMember.Titles, _ instrSignatPath))) _ With {.CertificateId = p.Key} lblMessage.Text = CStr(certs Is Nothing) lblMessage.Text = lblMessage.Text + "<br />" + CStr(certs.Count()) In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception. How is this possible?

  • Clearcase - selective merge.

    - by Keshav
    Hi, I have a peculiar Clearcase doubt. I cannot fully describe why I'm doing such a confusing architecture, but I need to do it (thanks to the mistake done by someone long back). Ok, here's a bit of detail: B1 is a contaminated branch where both my group's changes and another group's changes got mixed together so badly that there is no way of finding which code is whose). So the solution proposed is to create a new branch called B2 (at the same level as B1) and put all the unmodified code of the other group on it (The way to do that would be to merge B1 with B2 and then go about removing all changes from it till it becomes original). Then create a CR branch on B1 and keep only my group's newly added files or modified files on that branch. Finally create an integration branch out of B2 and merge the changes from CR branch of B1 to integration branch of B2. So here is what I did: (The use case is where I have dir D where file a, b and c are there. My group ended up modifying file a while b and c are not modified at all). There is a branch B1 on which there are files a, b and c. There is another branch B2. A merge is done from B1 to B2. Now B2 also has a, b and c. At this point both branch B1 and B2 are same. Now I delete file a from branch B2 (rmname). Now B2 has b and c only. I put a label to this branch called Label1. This makes the code with label Label1 as the unmodified code from other group. Now I create a sub branch called CR1 from B1 and delete all the files that are there in B2 branch (i.e b and c) such that it contains only the modified code from original code on it. In my case it is file a. At this point branch B2 with label Label1 has files b and c (those are unmodified code) and branch CR1 coming off B1 has only a (that is modified by us). Now I create another branch called integration branch that comes off B2 Label1. And then I do a merge of CR branch on to that expecting that it will have all three files a, b and c for me. All I'd need to do is to do a version tree view and see who modified what. But the problem I face is that since I had done a rmname of file a on branch B2 earlier to putting Label. The merge does not really take the file a from CR branch. How to I get around that problem. I want to selectively merge. Is it possible? sorry if it is a bad design. I'm not really conversant with Clear case and have limited options and time to clear some one else's mess.

  • What is Perl doing with this argument to push in this case?

    - by Morinar
    I just saw some code in our code base (and it's OLD code, as in Perl 3 or Perl 4 days) that looks like this (I'm simplifying greatly): my @array; push( array, $some_scalar ); Notice that the array in the push() doesn't have an @. I would assume that the code behind push knows that the first argument is supposed to be array so grabs the array from the array typeglob. Is that more or less it? If Perl is able to do that without problem, why would you need to include the @ at all?
