  • How does file creation work in Java

    - by Ankur
    I am trying to create a file using File newFile = new File("myFile"); However no file called "myFile" is created. This is within a Web application Project i.e. proper form to be pakaged as a WAR but I am calling it as part of a main method (just to see how this works). How can I make it so that a new file is created at a location relative to the current one i.e not have to put in an absolute path.

  • ASP.NET MVC routing and paths is js files

    - by HiveHicks
    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

  • pass string or data of local file between viewcontrollers

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • JVM process resident set size "equals" max heap size, not current heap size

    - by Volune
    After a few reading about jvm memory (here, here, here, others I forgot...), I am expecting the resident set size of my java process to be roughly equal to the current heap space capacity. That's not what the numbers are saying, it seems to be roughly equal to the max heap space capacity: Resident set size: # echo 0 $(cat /proc/1/smaps | grep Rss | awk '{print $2}' | sed 's#^#+#') | bc 11507912 # ps -C java -O rss | gawk '{ count ++; sum += $2 }; END {count --; print "Number of processes =",count; print "Memory usage per process =",sum/1024/count, "MB"; print "Total memory usage =", sum/1024, "MB" ;};' Number of processes = 1 Memory usage per process = 11237.8 MB Total memory usage = 11237.8 MB Java heap # jmap -heap 1 Attaching to process ID 1, please wait...

  • AuthSub target path prefix does not match the provided "next" URL

    - by dweebsonduty
    I am trying to use the Gcal API in PHP. I am using the ZEND framework function getAuthSubUrl($company) { $next = "http://$company.mysite.com"; $scope = 'http://www.google.com/calendar/feeds/'; $secure = false; $session = true; return (Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session)); } $authSubUrl = getAuthSubUrl(); echo "<a href=\"$authSubUrl\">login to your Google account"</a> I am not sure what I am doing wrong here. I am following the google example almost exactly. They do have $next = getCurrentUrl(); in their expample but I am getting undefined errors when I try that.

  • Add shadow to UIImage drawn in rounded path

    - by Tom Irving
    I'm drawing a rounded image in a UITableView cell like so: CGRect imageRect = CGRectMake(8, 8, 40, 40); CGFloat radius = 3; CGFloat minx = CGRectGetMinX(imageRect); CGFloat midx = CGRectGetMidX(imageRect); CGFloat maxx = CGRectGetMaxX(imageRect); CGFloat miny = CGRectGetMinY(imageRect); CGFloat midy = CGRectGetMidY(imageRect); CGFloat maxy = CGRectGetMaxY(imageRect); CGContextMoveToPoint(context, minx, midy); CGContextAddArcToPoint(context, minx, miny, midx, miny, radius); CGContextAddArcToPoint(context, maxx, miny, maxx, midy, radius); CGContextAddArcToPoint(context, maxx, maxy, midx, maxy, radius); CGContextAddArcToPoint(context, minx, maxy, minx, midy, radius); CGContextClosePath(context); CGContextClip(context); [self.theImage drawInRect:imageRect]; This looks great, but I'd like to add a shadow to it for added effect. I've tried using something along the lines of: CGContextSetShadowWithColor(context, CGSizeMake(2, 2), 2, [[UIColor grayColor] CGColor]); CGContextFillPath(context); But this only works when the image has transparent areas, if the image isn't transparent at all, it won't even draw a shadow around the border. I'm wondering if there is something I'm doing wrong?

  • System.InvalidOperationException: Failed to map the path '/sharedDrive/Public'

    - by d03boy
    I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have. public partial class TestPage : System.Web.UI.Page { protected DirectoryInfo dir; protected FileInfo[] files; protected void Page_Load(object sender, EventArgs e) { dir = new DirectoryInfo(Server.MapPath(@"\\sharedDrive\Public")); files = dir.GetFiles(); } } The aspx page looks kind of like this: <% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %> <ul> <% foreach (System.IO.FileInfo f in files) { Response.Write("<li>" + f.FullName + "</li>"); } %> </ul> When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.

  • Core Graphics Rotating a Path

    - by Scott Langendyk
    This should be a simple one, basically I have a few paths drawn with core graphics, and I want to be able to rotate them (for convenience). I've tried using CGContextRotateCTM(context); but it's not rotating anything. Am I missing something? Here's the source for drawRect - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 1.5); CGContextSetStrokeColorWithColor(context, [UIColor whiteColor].CGColor); CGContextSetShadow(context, CGSizeMake(0, 1), 0); CGContextBeginPath(context); CGContextMoveToPoint(context, 13.5, 13.5); CGContextAddLineToPoint(context, 30.5, 13.5); CGContextAddLineToPoint(context, 30.5, 30.5); CGContextAddLineToPoint(context, 13.5, 30.5); CGContextAddLineToPoint(context, 13.5, 13.5); CGContextClosePath(context); CGContextMoveToPoint(context, 26.2, 13.5); CGContextAddLineToPoint(context, 26.2, 17.8); CGContextAddLineToPoint(context, 30.5, 17.8); CGContextMoveToPoint(context, 17.8, 13.5); CGContextAddLineToPoint(context, 17.8, 17.8); CGContextAddLineToPoint(context, 13.5, 17.8); CGContextMoveToPoint(context, 13.5, 26.2); CGContextAddLineToPoint(context, 17.8, 26.2); CGContextAddLineToPoint(context, 17.8, 30.5); CGContextStrokePath(context); CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor); CGContextSetShadowWithColor(context, CGSizeMake(0, 0), 0, [UIColor clearColor].CGColor); CGContextFillRect(context, CGRectMake(26.2, 13.5, 4.3, 4.3)); CGContextFillRect(context, CGRectMake(13.5, 13.5, 4.3, 4.3)); CGContextFillRect(context, CGRectMake(13.5, 26.2, 4.3, 4.3)); CGContextRotateCTM(context, M_PI / 4); }

  • Usage of ||, OR in PHP

However all other pages are added CODE A. I am expecting CODE A only when $path is web_tjenester', 'webdesigndetails', 'vismahjemmeside', 'joomla', 'vismanettbutikk', 'vpasp' or 'artportfolio'. Could anyone point out my mistake and correct me please? Thanks in advance. --UPDATE-- The following works, but is there any ways shorten the code?

  • MinGW GCJ libiconv path problem

    - by Hussain
    I'm having a problem with the MinGW implementation of GCJ. I read that you have to install libiconv before you can use it. However, the documentation wasn't very specific, and it did not say where to extract the binaries and developer files (libiconv-bin and libiconv-lib). I have tried the following paths: $p = c:\mingw $p\libiconv-1.9.2-1-[bin|lib]\ $p\libiconv-[bin|lib]\ $p\mingw32\libiconv-1.9.2-1-[bin|lib] $p\mingw32[bin|lib]\libiconv $p\mingw[bin|lib]\liconv $p\bin\libiconv-1.9.2-1-[bin|lib] $p\bin\libiconv-[bin|lib] None of these work. Any help on where I'm supposed to put the libiconv files?

  • shared library path inconsistent from one host to another

    - by yan bellavance
    I built my qt app so that all the Qt modules it uses are contained in the same directory as the executable. It works on the machine I used to build the app and I made sure to test this by removing those shared libraries everywhere except in the current directory of the app. Doing a ldd shows that its looking for those libraries in the current directory and putting the executable by itself fails to open the exectuable. So this is all good but when I transfer this directory to a host machine it still cant find those libraries. what could be the problem?
