• How can I use SVN to manage my Firefox Extension project?

  - by 4AM

  I'm using SVN to manage my Firefox extension project, and this project contains an XPCOM component. Firefox is loading directly from my working directory by placing a text file with the working directory's path in the ./extensions directory of my user profile. When Firefox starts, my extension fails to load & overlay; examining the Error Console, I see that the error states that ".svn cannot be loaded as a component" - a reference to the .svn directory inside my "components" directory of the plug-in structure. Is there any way to get Firefox to ignore this directory, or get SVN to generate a working copy without the .svn directories in it?

• "Invalid Procedure Call or Argument", but only in a compiled or P-Code EXE

  - by Rob Perkins

  I have a VB6 program which I've been maintaining for ten years. There is a subroutine in the program called "Prepare Copy", which looks like this: Public Sub PrepareCopy() Set CopiedShapes = New Collection End Sub Where CopiedShapes is dimmed out as a VB6 Collection. That code is now kicking out a Runtime Error 5 -- Invalid Procedure Call or Argument. It appears from the interstitial debugging code that the error arises between the Public Sub PrepareCopy() and the Set CopiedShapes = New Collection lines. That's right. The VB6 error is happening between two lines of my code. I can think of no other explanation for this. It's behaving this way on my development machine and two client computers. It is only happening in runtime code, and does not appear to make a difference whether I compile it or use P-Code What I'm asking for here is speculation as to what causes this sort of thing to happen.

• Torotoisesvn import

  - by user481913

  Hi, My developer gave me a compressed file for the whole project from his subversion working copy. I uncompressed that file and used torotoisesvn import to put it into my repository which i host with projectlocker(a svn hosting provider). Now what i want to know is : 1) I want to view the files and the code that has changed since last revision. After doing the import the latest revision is at 8. I want to see what files and code has changed between revision no. 8 and revision no. 7 and maybe able to compare all of it upto revision no. 1. My question is can i do this ? 2)How to view these changes in projectlocker( or if it's the similar process with every svn host provider ) ?

• I work on local copies of files and upload them to a remote server on save. What version control sys

  - by 10goto10

  Here's my situation: My files are on a remote server (Linux). When I want to edit a file at home on my Windows machine, my editor (PSPad) downloads a copy. When I save the document, my editor uploads it to the server, overwriting the previous version. Is there a version control system, preferably GUI driven, that can handle this situation? Additional info: I probably can't install elaborate software on the remote server, but can on my own computer. Concurrent Versions System (CVS) is installed on the remote server. Uploading/downloading goes through an FTP-to-SFTP bridge set up with Bitvise Tunnelier.

• Use alternative browser with Subversion URLs

  - by Mark Howard

  We have subversion setup with http access through apache at http ://svn.local/ This provides access through svn clients and the standard svn repository browser. We also have a separate repository browser installed at http ://svn-browser.local/ (fisheye in this case). Is it possible to change the subversion/apache server so that browser requests are redirected to the subversion browser, but requests from svn clients go to the subversion server? Essentially, I'd like to use a single URL to identify a resource in both svn clients and the svn browser and be able to copy the url from a svn client into a web browser to have the enhanced functionality provided by the browser.

• (Ogre3D) Using a 3D texture slice as a 2D texture input.

  - by ~mech

  Hello, I am trying to do something with Ogre using 3D textures. I would like to update a 3D-texture by going through it slice-by-slice and recalculating the color values. However, in each step I also need to access the previous slice somehow to read the values. Setting up a slice as a render target is easy, but is it possible to feed such a slice as a 2D-texture input to a shader, or do I need to explicitly copy it into a separate 2D texture? Thanks.

• Tomcat startup fails with not a valid identifier

  - by Nigel

  I have tomcat 6.0.18 running on one server without a problem. With the exact same settings it fails to launch on my colleague's machine. He's even running from the same folder as me (I've stopped my copy while he tries to make it work) All we get when we fire off tomcat using bin/startup.sh is this: CATALINA_OPTS=-server -Xms768m -XX:+UseParallelGC -Xmx768m -XX:MaxPermSize=256m -XX:PermSize=128m -Djava.awt.headless=true: is not an identifier I had that definition in setenv.sh and moved it into startup.sh - same problem. Any suggestions? My brief look on google seem to indicate multiple IP address issues, but my server has two ethernet cards, and two IP addresses. Thanks.

• Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

  - by splicer

  I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

• File created using MODE_WORLD_READABLE not getting sent as attachment by email

  - by Dheeraj

  I created the SQLite DB using the following code: context.openOrCreateDatabase(dbName, Context.MODE_WORLD_READABLE, null); And tried to send it as attachment by email using the following code: Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND) .setType("message/rfc822") .putExtra(android.content.Intent.EXTRA_STREAM, Uri.fromFile(getDatabasePath(dbName))); startActivity(Intent.createChooser(emailIntent, null)); This opens the GMail compose activity with the attachment icon. But the recipient did not receive the attachment. This has been asked before. But it looks like there is no solution other than to copy the db file to SD card. My question then is: What is the use of the MODE_WORLD_READABLE flag if another app like GMail is unable to read the file?

• Python metaprogramming help

  - by Timmy

  im looking into mongoengine, and i wanted to make a class an "EmbeddedDocument" dynamically, so i do this def custom(cls): cls = type( cls.__name__, (EmbeddedDocument,), cls.__dict__.copy() ) cls.a = FloatField(required=True) cls.b = FloatField(required=True) return cls A = custom( A ) and tried it on some classes, but its not doing some of the base class's init or sumthing in BaseDocument def __init__(self, **values): self._data = {} # Assign initial values to instance for attr_name, attr_value in self._fields.items(): if attr_name in values: setattr(self, attr_name, values.pop(attr_name)) else: # Use default value if present value = getattr(self, attr_name, None) setattr(self, attr_name, value) but this never gets used, thus never setting ._data, and giving me errors. how do i do this?

• two HashMap iteration

  - by user431276

  I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

• How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

  - by Diogo K.

  I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

• Managing StringBuilder Resources in C#

  - by Jim Fell

  Hello. My C# (.NET 2.0) application has a StringBuilder variable with a capacity of 2.5MB. Obviously, I do not want to copy such a large buffer to a larger buffer space every time it fills. By that point, there is so much data in the buffer anyways, removing the older data is a viable option. Can anyone see any obvious problems with how I'm doing this (i.e. am I introducing more performance problems than I'm solving), or does it look okay? tText_c = new StringBuilder(2500000, 2500000); private void AppendToText(string text) { if (tText_c.Length * 100 / tText_c.Capacity > 95) { tText_c.Remove(0, tText_c.Length / 2); } tText_c.Append(text); } Thanks.

• Can profiler templates be migrated to newer versions of SQL Profiler?

  - by EBarr

  Is it possible to migrate Profiler templates to newer versions of SQL Server? In my case I want to take my SQL 2008 templates to 2012. I've tried (1) a straight file copy and (2) an export/import. In both cases the older templates run, but cannot be modified. Modifications result in the following error: I've got a bunch of custom templates and I'm trying to avoid recreating them by hand. Although, I guess that is the fallback position. Thoughts?

• Restoring using SyncBack without profiles

  - by Thomas Matthews

  I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

• TFS no release folder in build folder

  - by brian b

  I have a tfs build that works fine on the client, but when executed on the server, no actual binaries get created. When I go to the folder: \[MyServer]\builds[BuildName], I see BuildLog.txt ErrorsWarningsLog.txt Release.txt I expect to see a big \Release folder full of my dlls, but I get nothing. The error log reports no problems up until we ask the build to copy the binaries to our staging server. If I comment those out, I get no errors. CustomizableOutDir is true, DropLocation is set to something sensible BuildDirectoryPath is set to something sensible But no matter what, I just don't get any dlls built. Our local TFS guy is baffled too. Any suggestions?

• Another floating point question

  - by jeffmax329

  I have read most of the posts on here regarding floating point, and I understand the basic underlying issue that using IEEE 754 (and just by the nature of storing numbers in binary) certain fractions cannot be represented. I am trying to figure out the following: If both Python and JavaScript use the IEEE 754 standard, why is it that executing the following in Python .1 + .1 Results in 0.20000000000000001 (which is to be expected) Where as in Javascript (in at least Chrome and Firefox) the answer is .2 However performing .1 + .2 In both languages results in 0.30000000000000004 In addition, executing var a = 0.3; in JavaScript and printing a results in 0.3 Where as doing a = 0.3 in Python results in 0.29999999999999999 I would like to understand the reason for this difference in behavior. In addition, many of the posts on OS link to a JavaScript port of Java's BigDecimal, but the link is dead. Does anyone have a copy?

• Find top N elements in a Multiset from Google Collections?

  - by dfrankow

  A Google Collections Multiset is a set of elements each of which has a count (i.e. may be present multiple times). I can't tell you how many times I want to do the following Make a histogram (exactly Multiset) Get the top N values from the histogram Examples: top 10 URLs, top 10 tags, ... What is the canonical way to do #2 given a Multiset? Here is a blog post about it, but that code is not quite what I want. First, it returns everything, not just top N. Second, it copies (is it possible to avoid a copy?). Third, I usually want a deterministic sort, i.e. tiebreak if counts are equal.

• I'm getting the error in iTunes connect: The binary you uploaded was invalid. The signature was inva

  - by Joshua

  I went through the dev portal provisioning process twice now trying to get it to work, but to no avail. I don't think it's the second half (signature is invalid), I think it actually may have to with my binary. I have a warning in xcode that isn't helping me because I don't know what to do about it. And honestly I don't know how relevant this information even is. But it says: "Check Dependencies: Warning: The copy bundle resources build phase contains target's info.plist" The app runs perfectly in the simulator, and I haven't made any changes to the info.plist since I submitted the app to Apple last week. (this is an update) any suggestions?

• Is there a concise way to create an InputSupplier for an InputStream in Google Guava?

  - by Fabian Steeg

  There are a few factory methods in Google Guava to create InputSuppliers, e.g. from a byte[]: ByteStreams.newInputStreamSupplier(bytes); Or from a File: Files.newInputStreamSupplier(file); Is there a similar way to to create an InputSupplier for a given InputStream? That is, a way that's more concise than an anonymous class: new InputSupplier<InputStream>() { public InputStream getInput() throws IOException { return inputStream; } }; Background: I'd like to use InputStreams with e.g. Files.copy(...) or ByteStreams.equal(...).

• Write a dll that is accessable from VS 2003 VC++ code

  - by John

  I need to be able to write a DLL in either C# or VC++ that is accessible from code that is written in Visual Studio 2003 VC++. It looks like the code is unmanaged (uses * for pointers) VC++ and this DLL needs to be able to drop right in and be accessed by the current code. The DLL is an RS232 driver that needs to be able to return an int for an error code and pass back, by reference, some measured values, to the calling program. Will I even be able to write this in C#? If not, I only have access to Visual Studio 2005 or 2008. Will I be able to write my code in either, and will that DLL be able to be called from the current code base? Or do I have to go looking on ebay for a copy of VS 2003?

• Is it possible to build a Mac binary on a non-Mac unix machine?

  - by nbolton

  I would like to set up a Mac buildbot slave, but unfortunately it's not possible to install Mac OS X 10.5 on my XenServer hypervisor. So, I've had an idea, but not quite sure whether or not it'll work. The application is C++, and on Mac it's compile using GNU Make. I have a Mac desktop PC, and I was hoping I could copy the .h and .lib files on to a Linux box, and try to build against the Mac headers: #include <mach-o/dyld.h> #include <AvailabilityMacros.h>

• .NET desktop App remembering login to a webservice

  - by pete the pagan-gerbil

  I am in the planning stages of a .NET desktop app that will communicate with a web service. The web service requires a username and password, and a common feature in this sort of app is to save the user's credentials for the next logon. I've thought of a few ways of achieving this, but I am not sure what the most secure way would be. Should it be stored encrypted in a file (and could someone nefarious copy that file to their own machine and hence logon as the original person), or in the registry somehow (I've not done any registry work before, is it secure and would it work)? Are there any other options I might not have thought of?
