  • Detect start of a new band

    - by Dave Jarvis
    Using iReport, how do you set a variable (could be a parameter, or a value in the REPORT_PARAMETERS_MAP) to Boolean.TRUE at the start of a new band? There are some fields in the header that should only be displayed after a specific band has started being filled. Thank you!

  • Delphi Path Variables

    - by user337340
    Hey Everyone, I've got what I'm hoping is a simple question. In the Delphi IDE, the path to the Delphi installation is specified as $(DELPHI). I am wondering if there is a way to create my own path indicators, such as $(MY_LIBRARY) or something similar. I thought $(DELPHI) was specified as an environment variable, but apparently not. Any ideas? Thanks all! ~DJ DJ Quimby

  • NSString stringWithFormat swizzled to allow missing format numbered args

    - by coneybeare
    Based on this SO question asked a few hours ago, I have decided to implement a swizzled method that will allow me to take a formatted NSString as the format arg into stringWithFormat, and have it not break when omitting one of the numbered arg references (%1$@, %2$@) I have it working, but this is the first copy, and seeing as this method is going to be potentially called hundreds of thousands of times per app run, I need to bounce this off of some experts to see if this method has any red flags, major performance hits, or optimizations #define NUMARGS(...) (sizeof((int[]){__VA_ARGS__})/sizeof(int)) @implementation NSString (UAFormatOmissions) + (id)uaStringWithFormat:(NSString *)format, ... { if (format != nil) { va_list args; va_start(args, format); // $@ is an ordered variable (%1$@, %2$@...) if ([format rangeOfString:@"$@"].location == NSNotFound) { //call apples method NSString *s = [[[NSString alloc] initWithFormat:format arguments:args] autorelease]; va_end(args); return s; } NSMutableArray *newArgs = (NSMutableArray *)[NSMutableArray arrayWithCapacity:NUMARGS(args)]; id arg = nil; int i = 1; while (arg = va_arg(args, id)) { NSString *f = (NSString *)[NSString stringWithFormat:@"%%%d\$\@", i]; i++; if ([format rangeOfString:f].location == NSNotFound) continue; else [newArgs addObject:arg]; } va_end(args); char *newArgList = (char *)malloc(sizeof(id) * [newArgs count]); [newArgs getObjects:(id *)newArgList]; NSString* result = [[[NSString alloc] initWithFormat:format arguments:newArgList] autorelease]; free(newArgList); return result; } return nil; } The basic algorithm is: search the format string for the %1$@, %2$@ variables by searching for %@ if not found, call the normal stringWithFormat and return else, loop over the args if the format has a position variable (%i$@) for position i, add the arg to the new arg array else, don't add the arg take the new arg array, convert it back into a va_list, and call initWithFormat:arguments: to get the correct string. The idea is that I would run all [NSString stringWithFormat:] calls through this method instead. This might seem unnecessary to many, but click on to the referenced SO question (first line) to see examples of why I need to do this. Ideas? Thoughts? Better implementations? Better Solutions?

  • Referring to the public root in PHP - best practices

    - by Emanuil
    I've been using the $_SERVER["DOCUMENT_ROOT"] environment variable to refer to the public root in my apps. Now I'm realizing that that's not very reliable. I'm thinking about an approach where I define a constant in my index.php based on a magic constant. Something like that: define("PUBILC", __DIR__); I'm not sure about it though. What approach would you recommend?

  • Ruby refactoring in VIM

    - by fregas
    Hi, I'm a big fan of Resharper in visual studio. It has some awesome refactoring tools, similar to what you get in Ecplipse for Java. Is there anything like this for Ruby? Better yet, is there a plugin or something into VIM that does refactoring for Ruby code like renaming all instances of a method or variable, renaming classes sitewide, etc? thanks, craig

  • What is C# equivalent of PHP's mysql_fetch_array function?

    - by Mike Biff
    I am learning C#/ASP.NET and I am wondering what the C# equivalent of the following PHP code is? I know the userid, and I want to fetch the rows from this table into the array of the variable "row", so I then can use it as "row['name']" and "row['email']. $result = mysql_query("SELECT email, name FROM mytable WHERE id=7"); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { printf("Email: %s Name: %s", $row["email"], $row["name"]); } Thanks.

  • What is the best python module skeleton code?

    - by user213060
    == Subjective Question Warning == Looking for well supported opinions or supporting evidence. Let us assume that skeleton code can be good. If you disagree with the very concept of module skeleton code then fine, but please refrain from repeating that opinion here. Many python IDE's will start you with a template like: print 'hello world' That's not enough... So here's my skeleton code to get this question started: My Module Skeleton, Short Version: #!/usr/bin/env python """ Module Docstring """ # ## Code goes here. # def test(): """Testing Docstring""" pass if __name__=='__main__': test() and, My Module Skeleton, Long Version: #!/usr/bin/env python # -*- coding: ascii -*- """ Module Docstring Docstrings: http://www.python.org/dev/peps/pep-0257/ """ __author__ = 'Joe Author ([email protected])' __copyright__ = 'Copyright (c) 2009-2010 Joe Author' __license__ = 'New-style BSD' __vcs_id__ = '$Id$' __version__ = '1.2.3' #Versioning: http://www.python.org/dev/peps/pep-0386/ # ## Code goes here. # def test(): """ Testing Docstring""" pass if __name__=='__main__': test() Notes: """ ===MODULE TYPE=== Since the vast majority of my modules are "library" types, I have constructed this example skeleton as such. For modules that act as the main entry for running the full application, you would make changes such as running a main() function instead of the test() function in __main__. ===VERSIONING=== The following practice, specified in PEP8, no longer makes sense: __version__ = '$Revision: 1.2.3 $' for two reasons: (1) Distributed version control systems make it neccessary to include more than just a revision number. E.g. author name and revision number. (2) It's a revision number not a version number. Instead, the __vcs_id__ variable is being adopted. This expands to, for example: __vcs_id__ = '$Id: example.py,v 1.1.1.1 2001/07/21 22:14:04 goodger Exp $' ===VCS DATE=== Likewise, the date variable has been removed: __date__ = '$Date: 2009/01/02 20:19:18 $' ===CHARACTER ENCODING=== If the coding is explicitly specified, then it should be set to the default setting of ascii. This can be modified if necessary (rarely in practice). Defaulting to utf-8 can cause anomalies with editors that have poor unicode support. """ There are a lot of PEPs that put forward coding style recommendations. Am I missing any important best practices? What is the best python module skeleton code? Update Show me any kind of "best" that you prefer. Tell us what metrics you used to qualify "best".

  • How to set NSZombieEnabled for debugging EXC_BAD_ACCESS on release target for an iPhone app?

    - by Bobby Moretti
    I'm developing an iPhone application. I have an EXC_BAD_ACCESS that occurs only in the release target; when I build the debug target the exception does not occur. However, when I set the NSZombieEnabled environment variable to YES, I still get the EXC_BAD_ACCESS with no further information. Is it even possible for NSZombieEnabled to work when executing the release target? I don't see why not, since gdb is running in both cases...

  • C Programming - My program is good enough for my assignment but I know its not good

    - by Joe
    Hi there I'm just starting an assignment for uni and it's raised a question for me. I don't understand how to return a string from a function without having a memory leak. char* trim(char* line) { int start = 0; int end = strlen(line) - 1; /* find the start position of the string */ while(isspace(line[start]) != 0) { start++; } //printf("start is %d\n", start); /* find the position end of the string */ while(isspace(line[end]) != 0) { end--; } //printf("end is %d\n", end); /* calculate string length and add 1 for the sentinel */ int len = end - start + 2; /* initialise char array to len and read in characters */ int i; char* trimmed = calloc(sizeof(char), len); for(i = 0; i < (len - 1); i++) { trimmed[i] = line[start + i]; } trimmed[len - 1] = '\0'; return trimmed; } as you can see I am returning a pointer to char which is an array. I found that if I tried to make the 'trimmed' array by something like: char trimmed[len]; then the compiler would throw up a message saying that a constant was expected on this line. I assume this meant that for some reason you can't use variables as the array length when initialising an array, although something tells me that can't be right. So instead I made my array by allocating some memory to a char pointer. I understand that this function is probably waaaaay sub-optimal for what it is trying to do, but what I really want to know is: 1. Can you normally initialise an array using a variable to declare the length like: char trimmed[len]; ? 2. If I had an array that was of that type (char trimmed[]) would it have the same return type as a pointer to char (ie char*). 3. If I make my array by callocing some memory and allocating it to a char pointer, how do I free this memory. It seems to me that once I have returned this array, I can't access it to free it as it is a local variable. Many thanks in advance Joe

  • Accessing Arguments, Workflow Variables from custom activities

    - by yang
    I have a workflow composed of many custom activities. All these activities need to access startup arguments of the workflow itself. I can define InArgument inside all these custom activities and bind the workflow arguments to custom activity arguments but I am not comfortable with this solution. What is the best way to access workflow level argument and variable declarations from custom activities. Can I get them from ActivityContext? Thanks.

  • Using tramp with EmacsW32 and cygwin, possible?

    - by utvik
    Hi, I have some trouble setting up Tramp with EmacsW32 and cygwin. I have configured emacs to use cygwin as shell using w32shell. I also set the HOME enviromental variable to c:/cygwin/home/myusername Problem is that tramp seems to hang and that no connection is made: "Tramp waiting for prompts for the new shell". I have tried to turn on debugging, but still only see this message. Looking forward to get some tips on this. Thank you.

  • quick question about memory management in AS3

    - by TheDarkIn1978
    the following method will be called many times. i'm concerned the continuous call for new rectangles will add potentially unnecessary memory consumption, or is the memory used to produce the previous rectangle released/overwritten to accommodate another rectangle since it is assigned to the same instance variable? private function onDrag(evt:MouseEvent):void { this.startDrag(false, dragBounds()); } private function dragBounds():Rectangle { var stagebounds = new Rectangle(0 - swatchRect.x, 0 - swatchRect.y, stage.stageWidth - swatchRect.width, stage.stageHeight - swatchRect.height); return stagebounds; }

  • Windows application data directory

    - by Stefan
    With the environment variable %allusersprofile% I can get the directory where common settings are stored. But most programs store their settings in the sub-folder "anwendungsdaten" (German, application data). Is there a way to get the direct path to this folder? The problem is that its name is language dependent. Thanks.

  • How to get absolute path from path with system path variables?

    - by The_Fox
    Is there an easy way to translate a path with system path variables to an absolute path? So %ProgramFiles%\Internet Explorer\hmmapi.dll becomes C:\Program Files\Internet Explorer\hmmapi.dll I like to know if there is an API call that can do this, or do I have to do this the hard way and detect %..% sequences and replace them with the appropriate environment variable?
