I recently changed from developing iOS apps on a MacMini to a new MacBook Pro (2.2 GHz Intel Core i7). While working in XCode, I occasionally get pop-ups when the system is apparently trying to do an autosave and runs into a problem.
The pop-ups state "The document [filename] could not be autosaved. The file has been changed by another application. Click Save Anyway to keep your changes and save the changes made by the other application as a version, or click Revert to keep the changes from the other application and save your changes as a version."
Examples of the filename are: AppDelegate.m, MyLoginViewController.m. There shouldn't be anything else that is changing those files.
I can't do anything within XCode until I choose one of the options. Sometimes it seems like the system is trying to overwrite my newest code with an old version of my code, sometimes it seems like it is trying to save my newest code. So, sometimes Revert is what I need to do to keep my current version, and other times Save Anyway is what I need to do. However, sometimes, I can't tell what the system is trying to do and I choose the wrong option and lose hours of work.
This has happened numerous times over a span of three weeks.
I am using OS X 10.7.2 and XCode 4.2.1. The code is on my MacBook's hard drive.
Does anybody have any idea why this is happening?
Thank you.
This is a huge problem, and it looks like it's Lion's force-fed "file-versioning" that is destroying work.
I typed quite a bit of code into my source and saved it regularly (pretty much after every complete paragraph). Suddenly I couldn't find an entire section that I'd just written. I even did a project-wide search, in case I'd accidentally entered it in the wrong file. Suddenly Xcode raised a dialog saying it couldn't autosave the file because it had been modified externally. Did I want to "revert", or save what was in the editor?
In the several times I've seen this come up on two systems over the past few weeks, I've chosen to save what's in the editor, thinking that obviously it must be the most recent version. WRONG. I hit "Revert", and the block of code reappeared.
There is so much wrong here, it's hard to decide what's the most offensive.
Confirming that this happens on XCode 4.3.2 on an iMac running 10.7.4.
I have found that this bug may be related to having the same file open in more than one tab or window in XCode. If you carefully avoid ever having more than one window open on a given file at a time I think you can avoid this problem. However, it undermines the very useful ability to apple-click method names to navigate to the file that contains them.
This has cost me hours of original work and been the source of immense frustration. The derisive comments from others are simply inadequate.
I heard they had a complicated fix for it already at Apple, but unfortunately, it was "accidentally lost" and now they can't remember which files need what changes to make it work again. :-/

I have spent the last 4 days coding 20 hours a day to make my first self guided project ever for iOS. I had a working prototype and decided to tackle the layout for landscape mode. Long story short, in my fiddling I made mistakes that ruined portrait mode and so I (being a complete novice in Xcode and to programming) accidentally clicked discard all changes thinking it would reset me to my last save. It ended up wiping my whole file and dumping some of the old contents into the trash.
I could only find half my project in the trash so I was hoping I could recover the code from my test iPhone that has an older version of the program saved on it and just start again from there (with backups this time).
My iPhone is a physical version (not the Simulator)
When you said Discard All Changes, you were warned that this would discard all changes. If you went ahead and did it anyway, you have only yourself to blame: you were warned! You are now back your previous commit. Nothing after that is recoverable.
The correct procedure would have been, not to discard your changes, but to commit them! Now the current state of things would have been saved, and you could then proceed to work your way backwards to a working state of things in a recoverable and systematic manner.
By the way, this is not an Xcode matter or a programming matter; it's a version control matter. It's very good that you are using git, but perhaps you should pause and read up on it before you continue using it.
Unfortunately it is likely that you are out of luck here. Normally you would commit the changes and then, if you don't want them, you can revert back (and forward) as you wish. If you had commited (or stashed/staged) then you would be ok.
But...
There is a small possibility that Finder can help you though. Read this answer and see if that helps.
Basically, quit Xcode, open the file that you were working in using TextEdit, go to File > Revert To > Browse All Versions and see if you can restore one that you previously used. Do this for each file and then reopen Xcode and keep your fingers crossed and pray to the code gods!
I'm having some kind of problem with my project that me and my friend is working on. When I try to open the project that I've been working on it gives me an error message saying that "one or more lines were too long and have been truncated" and thus I can't see my code or GUI. When my friend opens the project on his computer (The project is on dropbox so it's the same file) there's no problem at all. I've googled but couldn't find anything. I just did a repair of RAD Studio but no luck. We have 2 forms and a unit that we use, the unit and the mainform isn't working for me but the second form is no problem.
Thanks!
Make a copy of your project directory.
Search your harddisk for XXXX.pas and XXXX.dfm
Hopefully there will be some temperary files that match - like "mylostform.dfm.~1307~" . copy the newest to your project directory, and rename them to "mylostform.dfm" and "mylostform.pas".
Kind regards,

From the comments, you have Dropbox, and the Restore functionality is available, but using it would cost you a week's worth of work.
If I was in that situation, here's what I would do:
Copy the current file to somewhere else (My Documents, for example).
Use Dropbox Restore to get the old version that works.
Make a copy of this, because you're going to be modifying it
Ensure that you can open it in the IDE.
Use Beyond Compare to open the two files side-by-side. (If you don't have this, you really should!)
If they're completely different from each other, you have a serious problem. If not, you'll see the changes you've made. Start copying changes one at a time, and after each change, save and try to open it in the IDE.
At some point, you won't be able to. That's where your problem lies. Now you can fix it!
I have done all the searching and can't find a solution to this weird problem that's been bugging me for about 5 hours. I started this app in Lazarus, but then took it across to D5pro to see if I could solve the problem. Thought it might have been a Lazarus "thing."
In D5, I have an app fully-working (so far so good) and I decided to try some different approaches to the look and feel so I "Save Project As" into a new folder. I then went through all of the included Units and saved them to the new Folder. I copied the two OpenSSL .DLL to the new folder. Did a compile and run and it all works fine. Well, almost.
When I tried the new app, the POP3 Unit crashes at "Login"
I have stepped through and all of the basic login stuff, Server, Name, SSL parameters etc is identical to the former version.
I went back to the original app and did a full Build and it still worked fine. I did a full Build on the new app and it still crashes at Login.
It gets through the pop3.Sock.SSLDoConnect() OK, but comes back from pop3.Login() with an error 10061 which according to the BlckSock Synapse-Unit, means "Connection refused."
When it returns from this call Result:=ssConnect(s, #name, SizeOfVarSin(name)); which I assume is in the .DLL it has a Result of -1 which then triggers the GetLastError and that is "10061 - Connection refused"
As far as I can find, everything is identical between the two projects. All Library Paths are in the Environment and not within the project.
Any thoughts and suggestions?
There is not much to work with. Can you see all parameters in the debugger on the various external call moments?
A change of compiler of course can make hidden bugs come to the surface, just like e.g. optimization. A well known difference is that the life time of temps might vary (see here).
Probably you need to nail the defining difference first. As with Delphi, the debugger is your friend here.
OK, problem solved.
Sir Rufo, it was a good idea but it did not help, but thanks for trying.
I had copied the ssleay32.dll into the new app folder BEFORE I started compiling. It did not work. I did a full Build and it still did not work.
I decided to delete the ssleay32.dll and libeay32.dll and do a full Build. I ran it and of course it crashed, but this time I expected that.
I then copied the two .ddl back into the new app folder and did another full Build.
Bingo problem solved. Seems weird but it is working with both Lazarus and D5. Something to do with the way the .dll gets linked into compiled .dcu.
Doing the Build with no .dll available cleared that. Dropping the .dll back into the Folder and another Build got the .dll linking correctly included into the .dcu.
Aaarrggghhhhh :)
I am trying to use an application called CLUT.exe which is an old application for MS-DOS that can be used to reindex NTX files for DBF databases.
(This is not the main topic, but I am just writing this if someone wants to test the app and don't trust at all about the content).
The problem starts when trying to run the command line version through console (cmd.exe) and this error appears:
C:\>CLUT.exe [arg1] [arg2] [arg3]
run-time error R6009
- not enough space for environment
So, according to what I've searched, this could be a possible solution:
http://support.microsoft.com/default.aspx?scid=kb;en-us;230205
but it doesn't work and every alternative that I found to solve this over the internet is the same.
Another alternative could be to make right-click in the .exe file, go to Properties then Memory tab and increase the Initial environment memory from Auto to the max value but it doesn't work too.
Well, I am stuck and no "possible" solution is working for me. If someone is interested, knows more about this issue and want to test, you can download the application from here (click "Free Download" green button):
http://www.filebasket.com/free/Development-Clipper-programming-language/clut-exe/13996.html
or directly from my DropBox:
https://dl.dropbox.com/u/15208254/stackoverflow/clut_214.rar
Just to know, I am using Windows 7 and the CLUT.exe application is a Clipper based app (old programming language) that may run under windows console (cmd.exe).
Wikipedia does mention other dos emulators but, oddly, doesn't mention BOCHS.
Reindexing NTX files is not a difficult thing to do, and can be done with tools other than CLUT. For example, many of the utilities listed on this part of Download32 could be used. Otherwise, you could write your own using Harbour Project or xHarbour. Or contact me off list and I'll cook up something in Clipper 5.3.
LATER
If I read the README correctly for CLUT, it's a replacement for the DBU utility that comes with Clipper 5.x. I can supply you with a build of that if you're unsuccessful with other approaches.
I'm developing an application on two different machines (home and work) and while the home one seems to run just fine, the work one is, for lack of a better word, possessed. It has been exhibiting the following issues:
When loading the application, it will start at the simulator's main screen instead of starting the application at random intervals. You can start the application and have it work fine, then close the simulator, reload, and have the same codebase not load.
Going to applications doesn't show the application itself, in fact it never does.
Trying to load the applications cod file (File->load java program) never works. Tried the steps in this thread, with unreliable results.
Extremely small changes, such as modifying the value of a width variable by one, commenting out a function such as makeMenu or adding a button will cause code to no longer work, with no errors shown by the IDE.
Using clear.bat with sometimes work, sometimes not. Same with manually removing all files with the name of the project.
reinstalling the eclipse environment and the blackberry plugin did nothing more then burn off an hour.
having "load on startup" in the blackberry_app_descriptor.xml file is set.
Both systems are using Eclipse 3.5.1, BB plugin for eclipse 1.1 beta, Java 4.5 with the 8300 simulator. THe only difference that I am seeing is the operating system between the two systems. The work one being XP Sp3, home being vista. THe vista one isn't perfect, but I can test variable changes without flipping a coin to see if the app will even load or not.
I've tried the solutions that were similar on this forum, such as this one, but it looked to be that those solutions are dated as none of the options for the steps existed in my eclipse install.
So has anyone ran into such baffling behavior, and can it be fixed? Anything that I might have missed that could be tried?
I've been seeing this behavior with the new 1.1 plugin, the application doesn't load on startup and the FIle->load java program doesn't help. For me, the solution was I have to run a clean build every time, that is the eclipse clean and build instead of just build, not the clean.bat... Hope this helps!
Try clearing resources that have improper naming structure in your projects stuff with spaces or special character in the name of the file.
It took me two days to figure out.
One solution i got regarding your problem.
As I See Please run the application first time as Run as blackberry simulator
that is got start and here pick up run and then Run as Blackberry simulator
