• Email SMTP validator

  - by Hrvoje

  I need to send hundreds of newsletters, but would like to check first if email exists on server. It's called smtp validation, at least i think so, based on my research on net. There's several libraries that can do that, and also a page with open-source code in asp (http://www.coveryourasp.com/ValidateEmail.asp#Result3), but I have hard time reading classic asp, and it seams that it uses some third-party library... Does someone have code for smtp validation in c#, and/or general explanation of how it works?

• How do Python and PHP compare for ecommerce?

  - by Ibn Saeed

  If I were to start an ecommerce store, which language would you suggest I start with? Python or PHP? And would it be wise to use Python for an ecommerce site in favor of PHP? PHP has lots of shopping carts, both open source and commercial. Is Python the future of Web Development ? Edit: I would like to clear out that i am not asking for Shopping carts solutions and links to them.

• Load a list of localized strings at once in IOS

  - by Victor Ronin

  I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.

• Java equivalent of C++ std::map?

  - by Rudiger

  I'm looking for a Java class with the characteristics of C++ std::map's usual implementation (as I understand it, a self-balancing binary search tree): O(log n) performance for insertion/removal/search Each element is composed of a unique key and a mapped value Keys follow a strict weak ordering I'm looking for implementations with open source or design documents; I'll probably end up rolling my own support for primitive keys/values. This question's style is similar to: Java equivalent of std::deque, whose answer was "ArrayDeque from Primitive Collections for Java".

• How does Eclipse/IDEA/etc. debugger obtain the information about local variable values and watch exp

  - by Bubba88

  I always thought that varibales are mapped to stack locations once your Java source is compiled; additionally, they may include the info about the variable names and their scope in classfiles, but that's optional AFAIK. The question is - how do my Eclipse/IDEA IDEs allow me to set a watch expression containing the local variable name? To me, it's hard to understand :)

• Show context menu when link is long pressed in TextView

  - by Al

  I have a TextView with its MovementMethod set to LinkMovementMethod. Text added to the TextView is a combination of normal text and URLs. For URLs, I would like to offer a context menu when the URL is long pressed for doing things such as copying the address. I've had a look at the source for LinkMovementMethod but it doesn't seem to have any long pressed related code I could override. Any ideas on how to go around achieving this?

• How do I solve "405 Method Not Allowed" for our subversion setup?

  - by macke

  We're serving our source code using VisualSVN running on Windows Server 2003. Recently, we split a portion of a project into a new project in it's own repository, and then linked it back to the original project using svn:externals. Since then, we've been having issues when we try to commit files with Subclipse. The error we're getting is: svn: Commit failed (details follow): svn: PROPFIND of '/svn': 405 Method Not Allowed (https://svn.ourserver.com) Googling for a while didn't really help, our config seems to be correct. It should also be noted that we've been running this server for a while no without these problems and apart from splitting the project into two repositories, no changes have been made to the server (ie, config files are the same). It should also be noted that these errors only appear when we try to check in multiple files at once. If we check in one file at a time there are no errors. Also, it only appears in Subclipse as far as we know right now, Versions.app (OS X) seems to work fine so that is our current workaround. So, the questions is how do I analyze the error to find the cause and subsequently fix it? I'm by no means a svn guru and right now I'm clueless. EDIT: It seems we can check in multiple files in the same package, but not files from multiple packages. Also, when I "split" the project into two repositories, I imported the original repository with a new name. I did not do a dump and then import that dump. Could that be the source of our issues, and if so, how would I solve that? EDIT: After some jerking around it seems as though it is indeed related to when checking in files in different repositories. If I try to do a single commit in both Repo A and Repo B (referenced by svn:externals) at the same time, I get the error. Versions.app handles this correctly, but I guess it might just be doing two commits, not a single one. Subclipse fails miserably. For now, we simply do multiple commits, one for Repo A and one for Repo B, that works just fine. If anyone smarter than me could fill in the details why this is happening, whether or not this kind of setup is stupid etc, please go right ahead.

• Regular Expression Question

  - by zyq524

  I'm trying to use regular expression to extract the comments in the heading of a file. For example, the source code may look like: //This is an example file. //Please help me. #include "test.h" int main() //main function { ... } What I want to extract from the code are the first two lines, i.e. //This is an example file. //Please help me. Any idea?

• How to redirect an application's connection through a Socks5/SSH/HTTPS tunnel? Any recomendations of

  - by Pai Gaudêncio

  I need to tunnel the connections (mostly TCP) made by an application through Socks5, SSH or HTTPS. So far, I've found 3 ways to do this: api hooks, winsock lsp and a driver. I'm looking for advice on the best way to handle this, and any recommendations on SDK's that could abstract this task for me (free/open-source preferred, but commercial ones are welcome as long as the price is not high for a one-man-starting-company to afford). ps. I'm using .Net (C# and-or C++/CLI)

• WPF: How to properly override the methods when creating custom control

  - by EV

  Hi, I am creating a custom control Toolbox that is derived from ItemsControl. This toolbox is supposed to be filled with icons coming from the database. The definition looks like this: public class Toolbox : ItemsControl { protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } Toolboxitem is derived from ContentControl. public class ToolboxItem : ContentControl { static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } } Since the number of icons stored in a database is not known I want to use the data template: <DataTemplate x:Key="ToolBoxTemplate"> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> Then I want the Toolbox to use the template. <Toolbox x:Name="NewLibrary" ItemsSource="{Binding}" ItemTemplate="ToolBoxtemplate"> </Toolbox> I'm using ADO.NET entity framework to connect to a database. The code behind: SystemicsAnalystDBEntities db = new SystemicsAnalystDBEntities(); private void Window_Loaded(object sender, RoutedEventArgs e) { NewLibrary.ItemsSource = from c in db.Components select c; } However, there is a problem. When the code is executed, it displays the object from the database (as the ItemSource property is set to the object from the database) and not the images. It does not use the template. When I use the static images source it works in the right way I found out that I need to override the PrepareContainerForItemOverride method.But I don't know how to add the template to it. Thanks a lot for any comments. Additional Information Here is the ControlTemplate for ToolboxItem: <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

• How do I identify an ASP.NET MVC website?

  - by Alejandro

  I am trying to determine whether a company has websites built with ASP.NET MVC in their portfolio. Is there a reliable way of determining that without asking them assuming that I can visit the website in question in my browser? This might seem simple, but I wasn't able to find this information online. I would think that the lack of viewstate related stuff in the HTML source and the noun-verb URL structure would be good indicators. Are there any other indicators?

• ede-proj-regenerate does weird things with my Makefile

  - by Xavier Maillard

  Hi, I have created a really basic project (Make) like this: (ede-proj-project "zrm" :name "zrm" :file "Project.ede" :targets (list (ede-proj-target-makefile-program "zm" :name "zrm" :path "" :source '("zrm.c") ) ) ) When doing M-x ede-proj-regenerate RET and M-x compile RET RET (accepting make -k as my compile command), make keeps bailing with a **missing separator error. When editing my Makefile outside of Emacs (with the darn evil vi) and replacing spaces by tabs, it works. Is there anything special I should pay attention in order to have this work ? Regards
