• Installing PostgreSQL on Windows

  - by Ross

  I'm in a bit of a mess here. I installed PostgreSQL on my Vista computer a couple of days ago but then when asked to enter the password for the postgre user account I couldn't remember it (allegedly I was asked during setup but I don't remember that). Anyway, so I uninstalled Pg with the intention of reinstalling it, removed the user account, it's /Users/ directory and it's special privelleges ("Advanced user profile properties") but when I come to install Pg it seems to think the account still exists as when I supply a password during setup it says that it is not the correct password - meaning that the account still exists somewhere. Is there anyway I can recover this?

• AppData\Roaming folder in windows service project

  - by vikash

  I need a help on getting Special folder in windows service program. I used this code in my Windows Form application: Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); and got the path, ""C:\Users\\AppData\Roaming"* But if I run the same code in my Winows Service project I got the path: "C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\" But I need the earlier path (got in Windows Form). How do I get the same path in Service projet also. I have user setting file, log, config file in the "C:\Users\\AppData\Roaming" folder. So I have to refer the same path both in my Windows Form application and Windows Service project. Can somebody tell me, what is the difference here and how do i get the same path in both type of project? Thanks, sharath

• are there any tree libraries/widgets for (n)curses

  - by phatmanace

  Hi - I wondered if there were any tree libraries available for (n)curses. I'm trying to write a component that shows a tree of folders & was curious if there was a prebuilt curses component that could do this. I've checked 'core' curses as well as libraries like CDK - and I can't seem to find anything. If none exists, I'm not averse to building my own - but I can't seem to locate any decent tutorials on doing this, so any help in this regard would also be much appreciated. Thanks, Ace

• Eclipse: How to add an existing source folder?

  - by evilfred

  ARGH Eclipse is SO frustrating I have a directory called c:\RemoteSrc . Under this there are 3 directories which are currently source folders (I think? the icon is an open folder with a little orange grid in it) in my Eclipse project. I have dropped a new directory under c:\RemoteSrc which I also want to add to my project. BUT If I right click on my project and go "Build Path..." - "Link Source" and try to add it it tells me "Folder already exists with a different case". Yes i KNOW that the folder already exists THATS WHY IM TRYING TO ADD IT.

• Where does complexity bloat from?

  - by AareP

  Many of our design decisions are based on our gut feeling about how to avoid complexity and bloating. Some of our complexity-fears are true, we have plenty of painful experience on throwing away deprecated code. Other times we learn that some particular task isn't really that complex as we though it to be. We notice for example that upkeeping 3000 lines of code in one file isn't that difficult... or that using special purpose "dirty flags" isn't really bad OO practice... or that in some cases it's more convenient to have 50 variables in one class that have 5 different classes with shared responsibilities... One friend has even stated that adding functions to the program isn't really adding complexity to your system. So, what do you think, where does bloated complexity creep from? Is it variable count, function count, code line count, code line count per function, or something else?

• How to Programmatically Identify a PI Font (a Dingbat) under OS X

  - by Glenn Howes

  There is a class of fonts called Pi fonts whose glyphs, under OS X, get mapped to the private Unicode space 0xF021-0xF0FF such that if you subtract 0xF000 from each unicode character to retrieve the 8-bit version of the character and be able to draw that character as if it were a standard Roman character. My question is how do I recognize these fonts? It's obvious the system can do so because there is a category on the Special Characters palette called "Pi Fonts" which apparently has the various such fonts installed on my system. In my case they are BookshelSymbolSeven, MSReferenceSpeciality, MT-Extras, Marlett, MonotypeSorts, Webdings, and various Wingdings. If I use the old fashioned QuickDraw routines to ask for the TextEncoding of these fonts, I get a value of 0x20000 which I do not see in the system header file TextCommon.h. Am I supposed to treat any font with a TextEncoding of 0x20000 as a Pi Font? And I'd rather not use any QuickDraw font handling routines for obvious reasons.

• Deploy CakePHP to a subfolder

  - by mgroves

  I have created a CakePHP 2 app, and now I'm trying to deploy it to a production web server. My app uses the default folder structure (app/lib/plugins/vendors), default htaccess, default routing, nothing special. I've been developing locally as if the app were in the root folder of the site (e.g. http://mycakeapp.localhost/ takes me to the site). But I'm deploying to a site (shared hosting) where that will not be the case (e.g. http://www.somedomain.com/mycakeapp). It doesn't work (I didn't really expect it to), so I assumed I had to tweak one or more htaccess files. I tried modifying the root .htaccess as suggested in this post, but that only partially worked (the link to the CSS didn't work, for instance): <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^mycakeapp$ mycakeapp/app/webroot/ [L] RewriteRule ^mycakeapp/(.*)$ mycakeapp/app/webroot/$1 [L] </IfModule> So what should I do to all the htaccess files to make this CakePHP site work in a subfolder?

• Strange profiling results: definitely non-bottleneck method pops up

  - by jkff

  I'm profiling a program using sampling profiling in YourKit and JProfiler, and also "manually" (I launch it and press Ctrl-Break several times to get thread dumps). All three methods give me extremely strange results: some tens of percents of time spent in a 3-line method that does not even do any allocation or synchronization and doesn't have loops etc. Moreover, after I made this method into a NOP and even removed its invocation completely, the observable program performance didn't change at all (although it got a negligible memory leak, since it was a method for freeing a cheap resource). I'm thinking that this might be because of the constraints that JVM puts on the moments at which a thread's stacktrace may be taken, and it somehow turns out that in my program it is exactly the moments where this method is invoked, although there is absolutely nothing special about it or the context in which it is invoked. What can be the explanation for this phenomenon? What are the aforementioned constraints? What further measurements can I take to clarify the situation?

• Perl, efficient parsing of csv file

  - by Mike

  I'm working on a project that involves parsing a large csv formatted file in Perl and am looking to make things more efficient. My approach has been to split() the file by lines first, and then split() each line again by commas to get the fields. But this suboptimal since at least two passes on the data are required. (once to split by lines, then once again for each line). This is a very large file, so cutting processing in half would be a significant improvement to the entire application. My question is, what is the most time efficient means of parsing a large CSV file using only built in tools? note: Each line has a varying number of tokens, so we can't just ignore lines and split by commas only. Also we can assume fields will contain only alphanumeric ascii data (no special characters or other tricks). Also, i don't want to get into parallel processing, although that might work effectively.

• Monitoring for non-pgp files

  - by Aheho

  For privacy reasons, I want to prevent my users from posting unencrypted files to my ftp site. It is company policy that all data exchanges of sensitive data be encrypted with PGP. I'd like to setup a program to monitor the ftp folders and whenever a new file is placed there, verify that it is in fact encrypted. I can't just rely on the file extension because in some cases, our trading partners require a specific filename that doesn't have a .PGP on the end. Is there a library or another method I can use to verify that a given file is encrypted? I'm using C# and .NET on a windows platform.

• Committing file deletions to svn repository whilst ignoring some other local mods

  - by TheJuice

  I have svn repository where I have scheduled some files and folders to be moved in the repository with svn mv. I also have some files that are peers of the files to be moved that have local modifications of which I only want a subset of those files to be committed along with the moves. e.g. the output of svn st would look like: D foo/bar D foo/bar/a.txt D foo/bar/b.txt M foo/exclude.txt M foo/include.txt A foo/whiz/bar A + foo/whiz/bar/c.txt A + foo/whiz/bar/d.txt To commit to the moves to the repository, I would need to perform the commit on foo but that would also commit the modifications to foo/exclude.txt and foo/include.txt. How would I commit only the deletions/additions as a result of the move plus the mods to foo/include.txt whilst excluding foo/exclude.txt? I have a feeling the answer lies with the --depth argument to svn ci but it's not clear to me how it will operate.

• Can i make an installer for my delphi programme?

  - by Hendriksen123

  I have made a delphi programme, which consists of a .exe and two custom file types that i have made (called Data.data and variables.data) I want to create a programme / find a programme that would place a copy of the main .exe in a folder in the program folders of XP, along with the .data files, and then place a shortcut to the programme on the desktop (ideally it would also put a folder in the start menu - all programmes with the programme. I should probably also make an uninstaller as well, that would remove the desktop shortcut, and delete the files. Is there a free piece of software i can use to create this, or is there any way i could achieve this myself through delphi?

• How to create a test environnement on the production FTP

  - by Clement Herreman

  Hello, I'm currently working on a symfony webapp, which is already on production. To develop and add/delete/modify functionnality of the model, I work on my laptop, using symfony 'dev' environnemment. I test if everything work fine, then I pray a little and deploy it on the prod server (with all the risk of data error, like when I add new not null attributes on the model, prod server configuration special stuff, version of php/apache etc.). The problem is that I would like to setup a "staging" server, which would be a copy of the production server (same database, same configuration apache/php), so that, if the deployment goes bad, the production user stay untouched and working, only the staging server is down. But my client has only 1 FTP available. So, the question is : can I run 2 symfony project, with different models, on the same FTP ? Or is there another way to do what I want to do ? Thank you !

• Need to change ip address in app.config in runtime without runnning as admin

  - by djerry

  Hey guys, There's a lot of post saying how to change info in the app.config and there are posts that say you shouldn't edit info in the app.config but store info in user folders. I understand these topics. But what i want is a combination of both. I have a wcf setup for my client in an app.config, which contains the endpoint address to which it should connect. When The server changes ip, or when a client is installed on a computer in another company, the user should be able to insert another ip-address which should be stored in the app.config. This cannot be stored in a file in appdata or something like that, as the client reads the info in the app.config on startup. How can i write (so remember the new ip-address) in the app.config when the client is installed in program files, the UAC is enabled and the program isn't run as an admin? Thanks in advance.

• Connect to https:// webservice in asp.net app

  - by webnoob

  Hi All, I have an ASP.NET website that is contacting a webservice. Everything works fine connecting via http but when I try https:// it can't connect. I don't seem to get any error from the website and the webservice logs show nothing, meaning nothing has connected to it. I can connect to my https:// webservice from a site like soapclient.com and request information, so the webservice and ports are working. Is there anything special I should be doing in order to connect to a https:// webservice over a normal http:// one in .NET? All I am doing at the moment is changing the URL it is connecting to to my secure one instead. I am using ASP.NET 2, IIS7 Thanks in advance.

• Fastest way to compress a database or .bak file and transfer it

  - by Nai

  As per the question title. I wonder if there are special programmes or commands that makes zipping up a .bak file and transferring it super quick. I read abour xp_cmdshell here but I'm not sure about the speed. My .bak file is about 12 gigs at the moment. Related to this is the possibility of using Red Gate's SQL Data Compare to just transfer the differential data across the network pipeline but I have never used SQL Data Compare before and I'm not sure how it goes about doing INSERTS on tables with Primary Keys and such. Also, not sure about the speed. Does anyone have any experience with this programme or similar programmes? Cheers!

• How do I manually log a user in with a MembershipProvider?

  - by Allen

  I'm experimenting with writing my own custom MembershipProvider in asp.net and I want to roll my own login page. We do some fairly special stuff at login time so we can't use the default login control so I need a way to manually log a user in. So far I haven't found anything on how to write your own login control so I'm here, wondering how I can manually log a user in via a MembershipProvider. I've tried Membership.ValidateUser("user", "pass"); and while that does call ValidateUser() on my custom MembershipProvider, and it does return true, it doesn't actually log me in. Btw I'm fairly new to the whole MembershipProvider stuff so if I'm not even on the right wavelength, feel free to let me know.

• How is Java Platform independent when it needs JVM to run ?

  - by happysoul

  Just started learning Java and I am confused about this whole independent platform thingy. Doesn't independent means that Java code should be able to run on any machine and would need no special software to be installed (JVM in this case has to be present in the machine)? Like, for example, we need to have Turbo C Compiler in order to compile C/C++ source code and then execute it.. The machine has to have the C compiler. guess I am confused..Somebody please explain in simple language or may be direct me to a tutorial that explain things in simple language ? that would be great I am just not getting the concept.

• How to Redirect Subdomains to Other Domain

  - by Codex73

  What I'm trying to accomplish with htaccess mod-rewrite: Redirect all sub-domains to new domain name w rewrite rule. e.g. test1.olddomain.com === test1.newdomain.com test2.olddomain.com === test2.newdomain.com test3.olddomain.com === test3.newdomain.com This is what I have so far which of course is wrong: Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^olddomain\.com$ [NC] RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=301,L] RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$ [NC] RewriteRule ^(.*) http://www.newdomain.com/$1 [R=301,L] RewriteRule [a-zA-Z]+\.olddomain.com$ http://$1.newdomain.com/ [R=301,L] Since I'm not a Regular Expression junkie just yet, I need your help... Thanks for any help you can give here. I know also we can compile these first two conditions into one. Note: The reason I don't redirect all domain using DNS is that a lot of directories need special rewrite rules in order to maintain positions on SEO.

• UIImageView in UITableCell gets a weird size

  - by Behlül

  Hi, I'm trying to place a UIImageView in a UITableViewCell. I create a special view called ProductView. In that view, I have several components, one of them being a UIImageView. I set this ProductView as content view of the UITableViewCell. Everything is drawn properly except the UIImageView. UIImageView gets scaled meaninglessly. It's height gets twice the height of the table cell size. I've spent hours trying to solve this problem. I've set the frame of UIImageView manually, I've called drawRect method of UIImage in UIImageView, neither of them worked. I'm thinking of replacing UITableView with a UIScrollView if I can't find a solution. Does anyone know how to solve this problem?

• Find folder name based on string value with batch

  - by MaQleod

  I need to return a full directory name from inside a specified directory that contains .default in the folder name. Basically I'm adding a line in a backup script to backup firefox bookmarks, but the profile name is going to be different on every machine and I need a way to find the folder the bookmarks.html file resides without knowing the firefox profile name I've looked at FIND and FINDSTR but neither seem to be what I need. I also looked at this post: http://stackoverflow.com/questions/2252785/windows-batch-file-get-folders-path-and-store-them-in-variable It was closer to what I'm looking for, but I just need a folder name, and to use something like regexp to find it Any suggestions on commands to look at or strategies to use?
