• Help modifying QuartzDemo example application

  - by BittenApple

  Can anyone please, oh sweet pain, please take me out of my misery by writing a simple example on how the heck you pass a number (int value) which gets created in 1 .m file to another .m file. In the apple demo application called QuartzDemo, there is a file called QuartzImages.m This file has the following line of code: [CODE]CGPDFPageRef page = CGPDFDocumentGetPage(pdf, 1);[/CODE] Notice the (pdf, 1) in that line. This number should be replaced with an integer variable. Now, there is also a file called MainViewController.m. In that file, there is a method? called -(void)viewDidLoad In that method, I want to assign a number to the integer variable which would replace the damn "1" with whatever number I want. I have been pulling my hair trying to get this done, reading beginning iPhone 3 Development book, dev documentation and God knows what not, without results. Any help would be greatly appreciated... Sigh.

• Error message when trying to insert method into touchesBegan

  - by Rob

  I am trying to create a new method within my TapDetectingImageView file and it's giving me a warning that it cannot find the method even though I have it declared in the .h file. The specific three warnings all point to the @end line in the .m file when I build it and they say: "Incomplete implementation of class 'TapDetectingImageView' ; 'Method definition for '-functionA:' not found" ; "Method definition for '-functionB:' not found" What am I missing? Am I not allowed to do this in a protocol file like TapDetectingImageView? In my .h file is: @interface TapDetectingImageView : UIImageView <AVAudioPlayerDelegate> { id <TapDetectingImageViewDelegate> delegate; } @property (nonatomic, assign) id <TapDetectingImageViewDelegate> delegate; -(void) functionA:(NSString*)aVariable; -(void) functionB:(NSString*)aVariable; @end In my .m file is: -(void)functionA:(NSString*)aVariable { // do stuff in this function with aVariable } -(void)functionB:(NSString*)aVariable { // do stuff in this function with aVariable }

• ack misses results (vs. grep)

  - by techpeace

  I'm sure I'm misunderstanding something about ack's file/directory ignore defaults, but perhaps somebody could shed some light on this for me: mbuck$ grep logout -R app/views/ Binary file app/views/shared/._header.html.erb.bak.swp matches Binary file app/views/shared/._header.html.erb.swp matches app/views/shared/_header.html.erb.bak: <%= link_to logout_text, logout_path, { :title => logout_text, :class => 'login-menuitem' } %> mbuck$ ack logout app/views/ mbuck$ Whereas... mbuck$ ack -u logout app/views/ Binary file app/views/shared/._header.html.erb.bak.swp matches Binary file app/views/shared/._header.html.erb.swp matches app/views/shared/_header.html.erb.bak 98:<%= link_to logout_text, logout_path, { :title => logout_text, :class => 'login-menuitem' } %> Simply calling ack without options can't find the result within a .bak file, but calling with the --unrestricted option can find the result. As far as I can tell, though, ack does not ignore .bak files by default.

• Downloading large files with AFNetworking

  - by goodfella

  I'm trying to implement downloading of a large file and show to user current progress, but block in: -[AFURLConnectionOperation setDownloadProgressBlock:] returns incorrect bytesRead and totalBytesRead values (they are smaller than they should be). For example: If I have a 90MB file and when it downloads completely, latest block invocation in setDownloadProgressBlock: gives me totalBytesRead value about 30MB. On other side, if file is 2MB large, latest block invocation gives correct totalBytesRead 2MB value. AFNetworking is updated to the latest version from github. If AFNetworking can't do it correctly, what solution can I use? Edit: I've determined that even if file is not downloaded completely (and this happens every time with relatively big file) AFNetworking calls success block in: -[AFHTTPRequestOperation setCompletionBlockWithSuccess:failure] I asked a similar question here about this situation, but didn't get any answers. I can check in code downloaded and real file sizes, but AFNetworking has no API for continuation of partial download.

• No download dialog with FileResult

  - by majkinetor

  I am returning File result from action triggered by the form post event. I can't get download dialog. Instead, if I use: return File(Encoding.UTF8.GetBytes(reportPath), "text/plain", "Report.csv"); I get path to the file upon ajax execution in the target div. When I use return File(reportPath, "text/plain", "Report.csv"); I get content of the file in the target div. Any thoughts ? The action is declared as [HttpPost] public virtual ActionResult ExportFilter(Model model) { string outputFile = CreateReport(model); return File(....) }

• Return a URI for local resource from a webservice

  - by peterkellyonline

  I want to design a webservice that returns a URI to a local resource on the webserver. What is the best (simplest) way to do this in C# using .asmx webservice? Or in other words - how can I get the URI for a physical file path in a webservice? Build a URI using the Uri class and the [WebService] namespace attribute? I know there is Server.MapPath(); that converts a virtual path into the corresponding physical path. I am looking for a way to do the opposite - having the physical path, I want to get not only the virtual path but the full URI. So if the webservice URI is http://some.server.com/services/example.asmx, the virtual path to the file I want to return is /Updates/file.xml and the physical path to that file is C:\Updates\file.xml what is the best way to get the URI http://some.server.com/updates/file.xml from that information? Thanks

• What the best approach to iterate and "store" files over a directory in C (Linux) ?

  - by Andrei Ciobanu

  I have written a function that checks if to files are duplicates or not. This function signature is: int check_dup_memmap(char *f1_name, char *f2_name) It returns: (-1) - If something went wrong; (0) - If the two files are similar; (+1) - If the two files are different; The next step is to write a function that iterates through all the files in a certain directory,apply the previous function, and gives a report on every existing duplicates. Initially I've thought to write a function that generates a file with all the filenames in a certain directory and then, read that file again and gain and compare every two files. Here is that version of the function, that gets all the filenames in a certain directory. void *build_dir_tree(char *dirname, FILE *f) { DIR *cdir = NULL; struct dirent *ent = NULL; struct stat buf; if(f == NULL){ fprintf(stderr, "NULL file submitted. [build_dir_tree].\n"); exit(-1); } if(dirname == NULL){ fprintf(stderr, "NULL dirname submitted. [build_dir_tree].\n"); exit(-1); } if((cdir = opendir(dirname)) == NULL){ char emsg[MFILE_LEN]; sprintf(emsg, "Cannot open dir: %s [build_dir_tree]\t",dirname); perror(emsg); } chdir(dirname); while ((ent = readdir(cdir)) != NULL) { lstat(ent->d_name, &buf); if (S_ISDIR(buf.st_mode)) { if (strcmp(".", ent->d_name) == 0 || strcmp("..", ent->d_name) == 0) { continue; } build_dir_tree(ent->d_name, f); } else{ fprintf(f, "/%s/%s\n",util_get_cwd(),ent->d_name); } } chdir(".."); closedir(cdir); } Still I consider this approach a little inefficient, as I have to parse the file again and again. In your opinion what are other approaches should I follow: Write a datastructure and hold the files instead of writing them in the file ? I think for a directory with a lot of files, the memory will become very fragmented. Hold all the filenames in auto-expanding array, so that I can easy access every file by their index, because they will in a contiguous memory location. Map this file in memory using mmap() ? But mmap may fail, as the file gets to big. Any opinions on this. I want to choose the most efficient path, and access as few resources as possible. This is the requirement of the program... EDIT: Is there a way to get the numbers of files in a certain directory, without iterating through it ?

• How to print absolute line number in uncaught exception?

  - by DSblizzard

  When error occured Python prints something like this: Traceback (most recent call last): File "<stdin>", line 2, in <module> File "<stdin>", line 8, in m File "<stdin>", line 5, in exec_st File "<stdin>", line 9, in exec_assign File "<stdin>", line 48, in ref_by_id IndexError: list index out of range where 2, ... , 48 are relative line numbers which are not very convenient. How to print absolute line numbers in such error messages? EDIT: Maybe it's a dumb question, but answer will facilitate development a little. I'm printing text in several files. When done, press shortcut which runs python and copies contents of current file to console. Proposed solution forces to press excess keystrokes (Ctrl+S, Alt+Tab) and create additional files. I hope I have put it clear.

• how do i use htaccess to make http requests work properly

  - by Gabriel

  I currently have css and javascript file calls (amongst other things) like the following: href="/css/default.css" src="/js/ui_control.js" putting the preceding / in to make the files relative to the root. This works great when my page is in the root of the domain. However, I'm currently in the middle of transferring my site to a new hosting provider and as such have a temporary URL which is: HOST-IP/~username As such, all file calls are trying to be called from HOST-IP/css/default.css etc instead of within the ~username sub-folder. Of course I can wait until the domain name servers propagate but that's beside the point. How would I go about writing a rule in the .htaccess file that would redirect all file calls that start with a /, from going to HOST-IP/FILE-CALL, and instead to go to HOST-IP/~USERNAME/FILE-CALL. ? Any ideas?

• RSA encrypted data block size

  - by calccrypto

  how do you store an rsa encrypted data block? the output might be significantly greater than the original input data block size, and i dont think people waste memory by padding bucket loads of 0s in front of each data block. besides, how would they be removed? or is each block stored on new lines within the file? if that is the case, how would you tell the difference between legitimate new line and a '\n' char written into the file? what am i missing? im writing the "write to file" part in python, so maybe its one of the differences between: open(file,'w') open(file,'w+b') open(file,'wb') that i dont know. or is it something else?

• JavaApplicationStub with CFBundleDocumentTypes

  - by mystro

  I'm trying to use CFBundleDocumentTypes to associate a custom file extension with my application. As far as I can tell, this seems to "work" -- my application launches when I double click the file. However, no callback is registered through the ApplicationListener events I setup in java. I used the code listed in http://stackoverflow.com/questions/1460193/set-default-file-association-mac-os-x-java-package-maker-installer to do the file association, and the file association itself appears fine, but it seems as if it is the application stub trying to launch the file, and thus fails. I added the Apple ApplicatinListener code to my java application at (similar to http://developer.apple.com/mac/library/documentation/Java/Reference/1.5.0/appledoc/api/index.html?com/apple/eawt/Application.html) but it doesn't seem like my application ever gets a call back. the code is similar to Application.getApplicatin().addApplicationListener( new ApplicationAdapter() { public void handleOpenFile(ApplicationEvent evt) { //some logging message here that I never get} }); Any help would be appreciated

• Seperate compilation in C++

  - by Pat Murray

  Suppose you are creating a class with multiple .cpp files (which each contain the implementation of a member function) and have the class' declaration in a .h file. Also, each .cpp file includes the .h file via the include directive. I was told that if you change the implementation of any of the member functions (.cpp files) that you will have to recompile every .cpp file in order to run the program. That is, if I had 5 member functions (each implemented in a .cpp file) and I changed the implementation of 1 of the .cpp files I would have to compile the 1 .cpp file I changed AND the 4 other .cpp files I didn't change in order to correctly run my program. My question, if the previous statement is true, is why is the statement is true? Any insight on this concept would be helpful.

  - by Carlos_Liu

  I want to debug on the customer's machine (Windows Server 2003) to track a problem, and out product is based on .NET 2.0. I want to use DbgCLR.exe to debug a file AAA.dll, what I did is: install .NET 2.0 SDK on the customer's machine (to get the DbgCLR.exe) copy the symbol file AAA.pdb to the same directory with AAA.dll get the source file for AAA.dll the AAA.dll will be loaded by w3wp.exe, so in the DbgCLR Tools-Attach to Process, then I choose w3wp.exe File-Open-File open the source file and add a breakpoint in the function which will be callled but the breakpoint seems do no work because there is an warning icon on it and says : the breakpoint will not currently be hit. No symbols have been loaded for this document. On my computer (Windows XP) which has the debug version of whole source code, I did nearly the same thing as above but the different is: I attached aspnet_wp.exe to do the debug and it works What should I do to let it work on the customer's machine?

• On iPhone, how do I check once per day to see if i should phone-home?

  - by Jann

  I want to check a file on the server only once each day (NSURL). And, no matter if I fetch the file or not, I do not run the function (to check for the file) again that day. This would SEEM easy... but I forsee issues. Say I had created a directory under the mainBundle: "/Library/runOnceEachDay/". Perhaps I could write to /Library/runOnceEachDay/20100601 knowing that file would only exist if I already ran the function. If it does not exist, run the function and after the function is successful write a zero length file with the date as the filename. Then check before running that function for "mainBundle/Library/runOnceEachDay/YYYYMMDD" whereas YYYYMMDD is today's date. If that file exists, do not run. I could run a housecleaning routine to clean that directory once/week or something. Any better ideas? Thanks!

• Project hosting on Google Code. Files are cahced?

  - by Frexuz

  I do not really understand how Google Code handles file versioning. I am building a jQuery plugin that anyone can access. Like so: <script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script> This script accesses other files on the same project (via ajax). The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names. But then I would have to change the filenames that the script loads. But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above) Is there a way to force a file to change when uploading with the same filename? PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.

• VBScript Issue Help Required.

  - by MalsiaPro

  I need a script that can run and pull information from any drive on a Windows operating system (Windows Server 2003), listing all files and folders which contain the following fields: The server is quite big and is within our domain. The required information is: Full file path (e.g. C:\Documents and Settings\user\My Documents\testPage.doc) File type (e.g. word document, spreadsheet, database etc) Size When Created When last modified When last accessed Also the script will need to convert that data to a CSV file, which later on I can modify and process in Excel. I can imagine that this data will be huge but I still need it. I am logged in as an administrator on the server and the script will need to also process protected files. As in previous posts I have read that the script will stop if such files are processed. I need to make sure that not a single file is skipped. Please note I have asked this question before but still have not got a working script. This is the script I got so far, file Test.vbs: Set objFS=CreateObject("Scripting.FileSystemObject") WScript.Echo Chr(34) & "Full Path" &_ Chr(34) & "," & Chr(34) & "File Size" &_ Chr(34) & "," & Chr(34) & "File Date modified" &_ Chr(34) & "," & Chr(34) & "File Date Created" &_ Chr(34) & "," & Chr(34) & "File Date Accessed" & Chr(34) Set objArgs = WScript.Arguments strFolder = objArgs(0) Set objFolder = objFS.GetFolder(strFolder) Go (objFolder) Sub Go(objDIR) If objDIR <> "\System Volume Information" Then For Each eFolder in objDIR.SubFolders Go eFolder Next End If For Each strFile In objDIR.Files WScript.Echo Chr(34) & strFile.Path & Chr(34) & "," &_ Chr(34) & strFile.Size & Chr(34) & "," &_ Chr(34) & strFile.DateLastModified & Chr(34) & "," &_ Chr(34) & strFile.DateCreated & Chr(34) & "," &_ Chr(34) & strFile.DateLastAccessed & Chr(34) Next End Sub I am currently using the command-line to run it: c:\test> cscript //nologo Test.vbs "c:\" > "C:\test\Output.csv" The script is not working.

• c# video equivalent to image.fromstream? Or changing the scope of the following script to allow vide

  - by Daniel

  The following is a part of an upload class in a c# script. I'm a php programmer, I've never messed with c# much but I'm trying to learn. This upload script will not handle anything except images, I need to adapt this class to handle other types of media also, or rewrite it all together. If I'm correct, I realize that using (Image image = Image.FromStream(file.InputStream)) basically says that the scope of the following is Image, only an image can be used or the object is discarded? And also that the variable image is being created from an Image from the file stream, which I understand to be, like... the $_FILES array in php? I dunno, I don't really care about making thumbnails right now either way, so if this can be taken out and still process the upload I'm totally cool with that, I just haven't had any luck getting this thing to take anything but images, even when commenting out that whole part of the class... protected void Page_Load(object sender, EventArgs e) { string dir = Path.Combine(Request.PhysicalApplicationPath, "files"); if (Request.Files.Count == 0) { // No files were posted Response.StatusCode = 500; } else { try { // Only one file at a time is posted HttpPostedFile file = Request.Files[0]; // Size limit 100MB if (file.ContentLength > 102400000) { // File too large Response.StatusCode = 500; } else { string id = Request.QueryString["userId"]; string[] folders = userDir(id); foreach (string folder in folders) { dir = Path.Combine(dir, folder); if (!Directory.Exists(dir)) Directory.CreateDirectory(dir); } string path = Path.Combine(dir, String.Concat(Request.QueryString["batchId"], "_", file.FileName)); file.SaveAs(path); // Create thumbnail int dot = path.LastIndexOf('.'); string thumbpath = String.Concat(path.Substring(0, dot), "_thumb", path.Substring(dot)); using (Image image = Image.FromStream(file.InputStream)) { // Find the ratio that will create maximum height or width of 100px. double ratio = Math.Max(image.Width / 100.0, image.Height / 100.0); using (Image thumb = new Bitmap(image, new Size((int)Math.Round(image.Width / ratio), (int)Math.Round(image.Height / ratio)))) { using (Graphics graphic = Graphics.FromImage(thumb)) { // Make sure thumbnail is not crappy graphic.SmoothingMode = SmoothingMode.HighQuality; graphic.InterpolationMode = InterpolationMode.High; graphic.CompositingQuality = CompositingQuality.HighQuality; // JPEG ImageCodecInfo codec = ImageCodecInfo.GetImageEncoders()[1]; // 90% quality EncoderParameters encode = new EncoderParameters(1); encode.Param[0] = new EncoderParameter(Encoder.Quality, 90L); // Resize graphic.DrawImage(image, new Rectangle(0, 0, thumb.Width, thumb.Height)); // Save thumb.Save(thumbpath, codec, encode); } } } // Success Response.StatusCode = 200; } } catch { // Something went wrong Response.StatusCode = 500; } } }

• List of dependency jar files in Maven

  - by Sindri Traustason

  Using Maven 2, is there a way I can list out the jar dependencies as just the file names? mvn dependency:build-classpath can list the jar files, but that will include the full path to their location in my local repository. What I need is essentially just a list of the file names (or the file names that the copy-dependencies goal copied). So the list I need would be something like activation-1.1.jar,antlr-2.7.6.jar,aopalliance-1.0.jar etc... ideally as a maven property, but I guess, a file such as build-classpath can generate will do. What I am trying to achieve is writing a Bundle-ClassPath to an otherwise manually maintained MANIFEST.MF file for a OSGi bundle. (You shouldn't need to understand this bit to answer the question.) To clarify: The question is not about how to write manifest headers into the MANIFEST.MF file in a jar (that is easily googleble). I am asking about how to get the data I want to write, namely the list shown above.
