  • How to have tortoisesvn Always freeze svn:externals for tags

    - by dnndeveloper
    Is this possible with tortoiseSVN?: Always freeze svn:externals for tags the scenario is our trunk will always use the 'head' revision for externals, however when we create 'tags' we would like for them to have a revision set for externals to properly 'freeze' them at a specific point in time. Thanks! Update Thanks to everyone for your feedback/info. Since I could not find anything that would completely meet our needs (tried smartsvn and svncopy.pl) I made a console app that so far has passed all our test cases. A high level overview: The app takes a repository URL then looks for all externals and adds the last commit revision for them - I do a "svn info" and get the "commit revision". The app works with both folder and single file externals. Here is the source code and complete setup files: http://svnxf.codeplex.com/

  • Enclosing service execution in try-catch

    - by Sorin Comanescu
    Hi, Below is the usual Program.cs content for a windows service program: static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new MyService() }; ServiceBase.Run(ServicesToRun); } } Is it a bad practice to enclose the ServiceBase.Run(...) in a try-catch block? Thanks.

  • ORMs and Constructors

    - by Harper Shelby
    I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

  • How to handle splitting a file under source control?

    - by sharptooth
    I have a .cpp file and .h file containing a class. Class.cpp contains the implementation and Class.h contains the definition. The class is overcomplicated so I want to separate some code and move it into a separate class. So I create NewClass.cpp and NewClass.h and move the code there. How do I handle this when the files are under SVN? I can simply "svn add" the two new files, but then they will appear as new and will have no history. I could instead "svn copy and rename" the two initial files and edit the the two old files and the two new files - then the two new files will have common history. Which approach is better from the point of version control? Should the new files share history with the old files or should they appear as new?

  • missing plot title in ggplot2

    - by Ben Mazzotta
    How can I create a plot title in ggplot2? Am I making a silly syntax error? The ggplot2 docs indicate that labs(title = 'foo') should work, but I can only get the arguments x='foo' and y='foo' to work with labs(). Neither ggtitle() nor title() worked either. Here is an example. x <- rnorm(10,10,1) y <- rnorm(10,20,2) xy.df <- data.frame(x,y) qplot(x,y, data=xy.df, geom='point', color=x*y) + labs(title = "New Plot Title", x='Some Data', y='Some Other Data')

  • Django paging object has issues with Postgresql QuerySets

    - by pivotal
    I have some django code that runs fine on a SQLite database or on a MySQL database, but it runs into problems with Postgres, and it's making me crazy that no one has has this issue before. I think it may also be related to the way querysets are evaluated by the pager. In a view I have: def index(request, page=1): latest_posts = Post.objects.all().order_by('-pub_date') paginator = Paginator(latest_posts, 5) try: posts = paginator.page(page) except (EmptyPage, InvalidPage): posts = paginator.page(paginator.num_pages) return render_to_response('blog/index.html', {'posts' : posts}) And inside the template: {% for post in posts.object_list %} {# some rendering jazz #} {% endfor %} This works fine with SQLite, but Postgres gives me: Caught TypeError while rendering: 'NoneType' object is not callable To further complicate things, when I switch the Queryset call to: latest_posts = Post.objects.all() Everything works great. I've tried re-reading the documentation, but found nothing, although I admit I'm a bit clouded by frustration at this point. What am I missing? Thanks in advance.

  • Is it possible to map a root domain URL to a Grails' controller?

    - by firnnauriel
    Let's have an example: A grails project, myproj, is deployed in Tomcat 6. It can be accessed anywhere thru this link: http://www.mycompany.com/myproj. Let's say we purchase another domain, http://newcompany.com, and we would like to point it to http://www.mycompany.com/myproj/url. If I go to http://newcompany.com/12345, it should be the same as doing http://www.mycompany.com/myproj/url/12345. Can anyone tell me if this is possible? How to implement it (change Tomcat 6 config, add code in UrlMappings.groovy)? Thanks in advance.

  • ASP.Net WebSite Membership AND C# Windows Form Membership

    - by user1638362
    This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

  • How do I compile for windows XP under windows 7 / visual studio 2008

    - by Jon Cage
    I'm running Windows 7 and Visual Studio 2008 Pro and trying to get my application to work on Windows XP SP3. It's a really minimal command line program so should have any ridiculous dependencies: // XPBuild.cpp : Defines the entry point for the console application. // #include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { printf("Hello world"); getchar(); return 0; } I read somewhere that defining several constants such as WINVER should allow me to compile for other platforms. I've tried the added the following to my /D compiler options: ;WINVER=0x0501;_WIN32_WINNT 0x0501;NTDDI_VERSION=NTDDI_WINXP But that made no difference. When I run it on my Windows XP machine (actually running in a virtualbox) I get the following error: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. So what have I missed? Is there something else required to run MSVC compiled programs or a different compiler option or something else?

  • Work flow for authentication and API use with Twitter on OAuth

    - by Gustavo Carreno
    I'm a bit confused about all this OAuth bruhaha in the sense that all the examples I can find are for web applications and none of them for desktop applications. I understand the Web application work flow, but that includes some redirections between the web app and twitter. How does one do this in an desktop application? How does the redirects work? Should I have to include a Web Browser object? Is there a way to go around this? Could anyone point me to resources instead of a full blown solution please? Thanks

  • compile error: The import xxxx cannot be resolved

    - by Zachary
    I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

  • Changing ylim (axis limits) drops data falling outside range. How can this be prevented?

    - by Alex Holcombe
    df <- data.frame(age=c(10,10,20,20,25,25,25),veg=c(0,1,0,1,1,0,1)) g=ggplot(data=df,aes(x=age,y=veg)) g=g+stat_summary(fun.y=mean,geom="point") Points reflect mean of veg at each age, which is what I expected and want to preserve after changing axis limits with the command below. g=g+ylim(0.2,1) Changing axis limits with the above command unfortunately causes veg==0 subset to be dropped from the data, yielding "Warning message: Removed 4 rows containing missing values (stat_summary)" This is bad because now the data plot (stat_summary mean) omits the veg==0 points. How can this be prevented? I simply want to avoid showing the empty part of the plot- the ordinate from 0 to .2, but not drop the associated data from the stat_summary calculation.

  • saving a records containing a member of type string to a file (Delphi, Windows)

    - by wonderer
    I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

  • Javascript form validation/sanitizing do i need regex here ?

    - by user318144
    I have a single form input that is for checking domains. Sometimes people type in www. before the domain or .com after the domain name. The service that i use to check availability automatically checks for all top level domains so when people add the .com at the end it becomes redundant. For example the string submitted is domainname.com.com which is clearly invalid. I understand you can do this on the server side but due to some rather weird circumstance i must use javascript for this. So is regex the solution here ? If so is there some kind of regex generator i can use for this or can someone point me in the right direction with a code snippet perhaps ? Appreciate any help thanks!

  • How do I get phpMyAdmin to connect to a local mysql server?

    - by bryan
    Hi everyone, I have my config.inc.php file, and have set my host name to localhost. Unfortunately, I have no idea what my username/password should be. Is that something I need to configure on the MySql side? I tried creating an arbitrary username/password (admin/password), but when I try to log into phpMyAdmin with those credentials, I get an error: (#1045 - Access denied for user 'admin'@'localhost' (using password: YES)) Can anyone point me in the right direction? (Sorry for the dumb question; I just haven't had to install mysql before. I've always had a host name / username / password given to me.) Thanks!

  • PHP/Mysql issues

    - by queryne
    Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

  • Seeking tutorial: introduction to ODBC with Delphi

    - by mawg
    I have a lot of embedded C/C++/Ada experience and an outdated smattering of Delphi plus some database stuff. Now I have to implement an app in Delphi which can manipulate MySql, Oracle, maybe MS Access. In short, I need ODBC. I need to programmatically created a database, define its structure and populate its contents, then later query its existence and programmatically search. I would prefer not to use 3rd party components, unless there is a compelling reason to do so (performance ought not to be an issue for the app, it won't have much data or be run often, at least not in v1.0) . Can anyone point me at a tutorial which can get me up to speed? Thanks

  • Dynamically/recursively building hashes in Perl?

    - by Gaurav Dadhania
    I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

  • How can I programmically construct the object reference?

    - by Bryan
    Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

  • Reading PGP key information

    can someone show a description of the information of what a pgp looks like if only the descriptions were there but not the actual information? something like (i dont remember if the values are correct): packet-type[4 bits], total length in bytes[16 bits], packet version type [4 bits], creation-time[32 bits], encryption-algorithm[8 bits], ...,etc,etc ive tried to understand rfc4880, but its tedious and confusing. so far, i am think i have extracted the 4 i wrote above, but i cant seem to get the rest of the information out. can anyone help? i know i can just find some pgp program, but the whole point of this is to allow me to learn how those programs work in the first place

  • SQLServer using too much memory

    - by Israel Pereira Valverde
    I have installed on my desktop machine (with windows 7) SQLServer 2008 R2 Express. I have only one local server running (./SQLEXPRESS) but the sqlserver process is taking ALL the RAM possible. With an machine with 3GB of RAM the things starts to get slow, so I limited the maximun amount of RAM in the server, and now, constantly the SQLServer give some error messages that the memory is not enought. It's using 1GB of RAM with only one LOCAL server with 2 databases completely empty, how 1GB of RAM isn't enought ? When the process start it's using an really acceptable amount of memory (around 80MB) but it's keep increasing until it reaches the maximun defined and start to complain about having not enought memory available. In that point I have to restart the server to use it again. I have read about an hotfix to solve one of the errors I got from sqlserver: There is insufficient system memory in resource pool 'internal' to run this query But it's already installed on my sqlserver. Why it's using so much memory?

  • New to javascript, why is jQuery such a beast?

    - by gnucom
    Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks
