• Placing figure in top-right corner of another

  - by Ivan Dubrov

  I want child figure (org.eclipse.draw2d.Figure) to be relative to the top-right corner of the parent (I want place some small icon, which will be ImageFigure, to be 12 pixels from top and right borders). Is there an existing layout manager that can layout child this way? The org.eclipse.draw2d.XYLayout is not capable of measuring position relative to corner other than top-left. Of course, I can: Write layout manager myself Layout children figure every time bounds are changed for the parent (in parent layout() method). However, I would like to know if some existing layout manager provides that functionality.

• Add / remove a port number to/from a URL with REGEX in PHP

  - by SuperDuck

  Hello guys, I've searched but was unable to find an existing regex function. Has anybody done this before? I wish to add a port number, or remove a potantially existing one from a url in php. To use in some functions which translate a given url to the secure one, unsecure one, etc. Now I need a second SSL secured site on the server so I need to dynamically add a port number while converting http to https, and remove any port number while converting from https to http. Thanks, Duck

• [C#] SQLite - Creating and changing databases on the fly

  - by Oskar Kjellin

  Today I use SQLite and send a database-file with the project. However I want the database to be created when the user first starts the software. Is there a way to copy the code needed to create a database based on the existing database? The problem is that when a user downloads a new version he might be tricked into copying over his last database and lose the data. I'd like a nice way to check the version of the database and modify it if I need new columns or tables etc. Or, if it does not exist at all, create a new database? I know I can probably make create the code to make the database from the beginning but I want it to be based on the existing database I have created by a gui.

• Frequent Netbeans freezes

  - by danilo

  I'm using Netbeans 6.8 for PHP projects located on network drives in a Windows network. Frequently, the IDE gets really slow (like a temporary freeze) to a point where it's totally unusable. At first it seems like a total crash, but after some time (might be sevaral minutes) the IDE works again as before. This happens with Netbeans 6.7 as well as 6.8 on my Windows XP 32-bit installation. I'm using Java 1.6.0_13. This is a fresh Netbeans installation, so it can't have to do with too many temp files. I assume it has to do with the frequent code checks that Netbeans does. It's probably not very fast when doing this over the network connection. But it can't be that this feature renders the IDE useless... This thread deals with the same issue http://forums.netbeans.org/viewtopic.php?t=5548. Does anyone know a solution to this problem?

• Pear SOAP and XAMPP on Ubuntu

  - by Vincent

  All, I have installed xampp for linux on ubuntu 9.10. The installation directory is /opt/lampp. The xampp website says PEAR comes with the installation.. I am relatively new to PEAR and want to know the answers for following: Is PEAR installed with xampp or need to be installed separately using synaptic package manager? I browse to /opt/lampp/bin directory and see "pear" there, but when i type it in the command line, it says "The program 'pear' is currently not installed. You can install it by typing: sudo apt-get install php-pear pear: command not found " I want to use PEAR:SOAP package in my PHP code. How to use that? Do I need to set any paths to the pear in my php.ini? Thanks

• WIX/DTF - How do I elevate deffered managed custom actions?

  - by Jarrod

  We are working on creating an installer using WIX. We have a couple of custom actions that are going to require elevation to run on Vista. Our MSI obviously elevates itself, because I get a UAC prompt and it writes keys to HKLM. Our managed DTF custom actions are apparently not running elevated. If I start the MSI from an elevated command prompt, the installation runs fine. The only workaround I have seen suggested (link) is to use another exe with a manifest as a bootstrapper to run the MSI. This is not a good solution, as it doesn't allow the user to modify the installation by selecting "Change" from the Add/Remove programs dialog. Our install has multiple features that can be customized, so we want this functionality. Does anybody know how to do this?

• Problem installing Maven plugin (m2eclipse) in Eclipse (Galileo)

  - by Nailuj

  I have Eclipse Galileo (for Java EE Developers) installed, and I'm now trying to get the m2eclipse Maven plugin installed as well. I follow the basic steps described at http://m2eclipse.sonatype.org/installing-m2eclipse.html, and it seems to be installing just fine. However, after restarting Eclipse after the install it doesn't seem to be anywhere. I should for instance have the ability to create a new maven project, but when the new-project wizard opens, there is no folder for Maven (I also cannot find any reference to it in the context menus of the existing projects I have). When I click at Help About Eclipse Installation Details, I find "Maven Integration for Eclipse (Required)" in the tab "Installed Software", yet another thing pointing towards a successful installation (but I can't find it under the "Plug-ins" tab, should it be there too?)... I feel like I'm just missing something very obvious, but right now I just don't see it...

• How to change a field value of a document (LotusScript)?

  - by Vassilen Dontchev

  Hello. In a new LotusNotes form I have a computed-value field ("NewOrdProdUID") which is set correctly with the unique ID of another existing document. I want to change the value of the field "NewProdAvail" in the existing document by means of LotusScript. I tried with this: Sub Querysave(Source As Notesuidocument, Continue As Variant) Dim session As NotesSession Dim db As NotesDatabase Dim ws As New NotesUIWorkspace Dim uidoc As notesUIDocument Dim odoc As notesDocument Set session = New NotesSession Set db = session.CurrentDatabase Set uidoc = ws.CurrentDocument Set odoc = db.GetDocumentByUNID(uidoc.FieldGetText("NewOrdProdUID")) Call odoc.FieldSetText("NewProdAvail", "0") Call odoc.Save(True, True) End Sub However the value of the field "NewProdAval" stays the same (3 in my case, not 0). Please, help me!

• How do I design the file storage issue?

  - by user102533

  I am working on an application that creates video files and stores them in a folder in the C:\ drive. I speculate that there will be a large number of these files in the future and we would run out of disk space at some point of time (on our VPS). When the time comes that we have to upgrade, we either plan to use one of the Cloud providers to store files or our existing provider can add another disk (say D:\ drive). Either way, I would want to design the app now in a way that in future, moving to different locations would not be an issue and would be transparent to the end user. The code that creates these files supports 2 ways: myObj.SetOutputToDisk(<path to store>); or myObj.SetOutputToMemoryStream(ms); If we go with the Cloud architecture, I assume we might have the following combination: Cloud Files + Existing VPS or Cloud Files + Cloud Windows Server Given the unknowns at this time, how would I go about designing this?

• Python lazy property decorator

  - by detly

  Recently I've gone through an existing code base and refactored a lot of instance attributes to be lazy, ie. not be initialised in the constructor but only upon first read. These attributes do not change over the lifetime of the instance, but they're a real bottleneck to calculate that first time and only really accessed for special cases. I find myself typing the following snippet of code over and over again for various attributes across various classes: class testA(object): def __init__(self): self._a = None self._b = None @property def a(self): if self._a is None: # Calculate the attribute now self._a = 7 return self._a @property def b(self): #etc Is there an existing decorator to do this already in Python that I'm simply unaware of? Or, is there a reasonably simple way to define a decorator that does this? I'm working under Python 2.5, but 2.6 answers might still be interesting if they are significantly different.

• Apache complex regex crashing with 500 error

  - by digitalspaghetti

  I have been working with an existing website out company has running until I finish developing the new site. I've been asked to add some additional functionality to booking pages that will automatically set a booking button based on passed parameters. The existing working regex is as follows: RewriteRule ^.+-(\d+)\.accommodation$ property_detail.php?id=$1 Which works fine with the url like below and passes through the URL. this-is-the-property-name.1234.accomodation However as a quick shiv, I am trying to do the following: this-is-the-property-name.1234.accomodation?override=true&start_date=2010-05-14&numbernights=2&sleeps=10&price=1012 The regex I came up with for this was: RewriteRule ^.+-(\d+)\.accommodation\?override=(\w+)&start_date=(19|20)[0-9]{2}[- /.](0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])&numbernights=(\d+)&sleeps=(\d+)&price=(\d+)$ property_detail.php?id=$1&override=$2&start_date=$3-$4-$5&numbernights=$6&sleeps=$7&price=$8 The regex is passing as valid in RegexBuddy - however it keeps causing a 500 error on the server. Can anyone help me get my head around this one?

• What's the cleanest way to programmatically kill and restart explorer.exe?

  - by Paul Accisano

  Greetings all, I'm working on a Windows program whose installation necessitates restarting explorer.exe. I know "Reboot your computer to complete the installation" is the standard method here, but I'd like my installer to give users the option of just restarting Explorer so they can start using my program immediately. What's the best way to do that? Of course I could just find and kill the process, but that seems rather icky. Is there some trick to, say, make Explorer think the user is logging off and close cleanly? Thanks!

• High density Silverlight charting control

  - by ahosie

  I've been looking into Silverlight charting controls to display a large number of samples, (~10,000 data points in five separate series - ~50k points all up). I have found the existing options produced by Dundas, Visifire, Microsoft etc to be extremely poor performers when displaying more than a few hundred data points. I believe the performance issues with existing chart controls is caused by the heavy use of vector graphics. Ergo one solution would be a client-side chart control that uses the WritableBitmap class to generate a raster chart. Before I fall too far down the wheel re-invention rabbit hole - has anyone found a third party or OSS control that will manage large numbers of data points on a sparkline?

• Run Python CGI Script on Windows XP

  - by daveywc

  I have a Windows XP machine that has Apache installed via a VisualSVNServer installation. I am . trying to get a simple python cgi script to run in my browser e.g. http://build.procepts.com.au:8080/hg/cgi-bin/test.cgi. However despite trying all the recommended approaches the browser only ever displays the plain text from the cgi script. Amongst many other attempted solutions I have followed the instructions contained here. My ultimate aim is to be able to use the Apache web server to serve repositories from a new Mercurial installation. Seeing as Apache is already installed from VisualSVNServer I thought I might as well make use of it. Is there some other trick to get this working?

• excel 2007 vba: how to refer to HPageBreaks

  - by notnot

  I'm trying to write a macro which can look into the list of horizontal page breaks that a worksheet keeps, and it seems like HPageBreaks should be exactly that. I can add or remove page breaks from it, but I can't seem to isolate the collection itself to look at its contents. Even adding a watch and looking at ActiveSheet.HPageBreaks just brings up a generic looking object with a count field equal to 0 regardless of existing page breaks. I'm really confused about this now. Is there any way to look into the existing page breaks within a sheet? A listing of what rows they occur on/between would be great.

• Symlinking (ln) faster than moving (mv)?

  - by Chad Johnson

  When we build web software releases, we prepare the release in a temporary directory and then replace the release directory with the temporary one just prepared: # Move and replace existing release directory. mv /path/to/httpdocs /path/to/httpdocs.before mv /path/to/$newReleaseName /path/to/httpdocs Under this scheme, it happens that with about 1 in every 15 releases, a user was using a file in the original release directory exactly at the time the commands above are run, and a fatal error occurs for that user. I am wondering if using symlinking like follows would be significantly faster, in terms of processing time, thereby helping to lessen the likelihood of this problem: # Remove and replace existing release symlink. ln -sf /path/to/$newReleaseName path/to/httpdocs

• MS Office SharePoint Server 2007 UI language change

  - by Alexander

  There is an existing app in MOSS, which allows to create polls for a call center, operators fill them out as they call targeted customers. Then this Web app outputs the results of this poll. Is it possible to change the interface language of this existing web app? Operators don't understand English. If it's not about language packs, it would still be easier for me to embed new names and labels, rather than rewrite in a system I am not familiar with. Also, is it possible to change the authentication type from Windows authentication to regular username/password check (username and password will be stored in DB or somewhere only for this site) If it is possible, can you direct me to some kind of tutorial, help or manual which would show how to do it? On MSDN it's written that language can't be changed, but I'm not sure whether it's about the Web app language. Thank you.

• How to build sqlite for Python 2.4?

  - by Verrtex

  I would like to use pysqlite interface between Python and sdlite database. I have already Python and SQLite on my computer. But I have troubles with installation of pysqlite. During the installation I get the following error message: error: command 'gcc' failed with exit status 1 As far as I understood the problems appears because version of my Python is 2.4.3 and SQLite is integrated in Python since 2.5. However, I also found out that it IS possible to build sqlite for Python 2.4 (using some tricks, probably). Does anybody know how to build sqlite for Python 2.4? As another option I could try to install higher version of Python. However I do not have root privileges. Does anybody know what will be the easiest way to solve the problem (build SQLite fro Python 2.4, or install newer version of Python)? I have to mention that I would not like to overwrite the old version version of Python. Thank you in advance.

• How to add a specific method to a particular scope in Visual Studion 2005

  - by pragadheesh

  Hi, In my visual studio project (C++), when i copy a method(meth1) of a particular scope say 'scope1' and paste it in the same code area, it is getting pasted in General Scope. i.e I want to add a method into a particular scope but when i try it is getting added in general scope. How can i solve this? For eg: There is an existing method: void add(int a, int b) { .... } This method is in File scope. i.e limited for that file. Now i want to add another method add2 in the same file scope. So I copied the existing add method and pasted it. void add2(int a, int b) { .... } But this method is getting added in the global scope and not in the file scope.

• MSI Install Folder Composed with Value from Radio Dialog

  - by Don Vince

  I'm using .NET2, I have an installer project. In the User Interface, I've created a RadioButtons (3 Buttons) dialog box. I've placed it before the Installation Folder Dialog. I wish to incorporate the value selected in the RadioButtons dialog as part of the Installation Folder. To do this I've placed the name of the variable amongst the path where I wish to use it in the DefaultLocation: [ProgramFilesFolder][Manufacturer]\[ProductName]\[BUTTON3] The effect of this is that the default value for the variable, BUTTON3 in the example above, is resolved as part of the folder, not the selected value. Anybody know how to make this variable use delayed expansion in some way to get the selected value?

• Subsonic custom mapping of objects to tables

  - by codekaizen

  Geeting, I'm using Compact Framework 3.5 and have tenatively settled on a custom build of Subsonic 3.0 to do data access. The trouble is that I am used to developing model-first but am also interested in keeping control of my DB schema. Therefore, neither ActiveRecord or Repository appears to meet my needs, and I want to use my existing POCO model and map it to my existing tables. I'm used to doing this via NHibernate and Entity Framework. After some investigation, it appears that I might be able to author a custom QueryMapping to give me the custom mapping I want. Before I start down this path, however, I'd like to see some kind of example of this being done. I can't seem to find any on the web, and wonder if anyone could give input on experience with Subsonic, model-first and a custom Table-per-Type and Table-per-Hierarchy mapping.

• Convert File System Website to IIS Website

  - by Noah

  We recently migrated from VS 2008 to VS 2010. The migration went fine, except for our web project. Before, in VS 2008, the site showed up as http://localhost/Website. Now, it appears as C:...\Website. It appears that when we did the migration, VS started to treat it as a file system website. I've tried removing the existing site and re-adding it as an existing website, but it still displays it as C:...\Website. Is there any way to convert it back to show it as a http://localhost/website, and run through IIS, as opposed to the default ASP.NET Development Server?
