The functionality to do this (the [rexec module][1]) has been removed from Python since 2.3 due to apparently unfixable security problems. There are several third-party hacks out there that purport to do this - the most thought-out solution that I have found is
[this Python Cookbok recipe][2], "safe_eval".
Am I reasonably safe if I use this (or something similar), to protect from malicious code, or am I stuck with writing my own parser? Does anyone know of any better alternatives?

And one of the requirements is that it should be optimized so the PC still on dial-ups common in the suburbs of my country could use it as well.
Now I am permitted to use Flash and/or Silverlight if that will help with the limited development time and user experience.
The heavy part of the geographical data are chunked into tiles and loaded like map tiles in Google Maps but that means I need a lot of HTTP requests.
Should I go with just javascript + HTML? Would I end up with a faster application regarding Flash/Silverlight? Since I can do some complex algorithm on those 2 tech (like DeepZoom). Deploying desktop app though, is out of the question since we don't have that much maintenance funds.

Some quirks are just quirks: when running VS2008 the play/pause media controls on my keyboard don't work (a Microsoft Wireless Natural Multimedia Keyboard ~ a snappy title if ever I saw one...).
Other quirks are more of a problem: a particular VS Solution makes use of a 'utility' class. I edited that class to add another field. No matter how many times I recompile/clean/manually delete the old dlls etc the compiler tells me there's no such field. I check the solution into SVN and check it out on my laptop (XP SP3 with fully patched VS2008) and it all works fine. No idea why.

This is an example of what a call might look like:
$.ajax({
url: "userCreation.ashx",
data: { u:userName, p:password, e:email },
type: "POST",
beforeSend: function(){disableSubmitButton();},
complete: function(){enableSubmitButton();},
error: function(xhr, statusText, errorThrown){
// Work out what the error was and display the appropriate message
},
success: function(data){
displayUserCreatedMessage();
refreshUserList();
}
});
The request might fail for a number of reasons, such as duplicate user name, duplicate email address etc, and the ashx is written to throw an exception when this happens.
My problem seems to be that by throwing an exception the ashx causes the statusText and errorThrown to be undefined. I can get to the XMLHttpRequest.responseText which contains the HTML that makes up the standard .net error page.
I am finding the page title in the responseText and using the title to work out which error was thrown. Although I have a suspicion that this will fall apart when I enable custom error handling pages.
Should I be throwing the errors in the ashx, or should I be returning a status code as part of the data returned by the call to userCreation.ashx, then using this to decide what action to take? How do you handle these situations?

Here's things I've covered;
- No memory leaks
- Tested performance on an actual device
- Doesn't crash :)
- Using correct certificates / profile
What I'm a little unsure about are how to configure the "Bundle Display Name" /"Bundle Identifier" and "Bundle Name". I understand the first is the text that's shown on the iPhone itself, but what about the last? Does this have to match Bundle Identifier?
Many thanks!

My initial thought was to just download a virtual appliance that we could load onto our host machine. The problem I am having however is that all the appliances I have found so far are stuck in svn version 1.4 or lower.
Does anybody know of an appliance that has svn 1.5 running? I don't need any of the other bits like issue tracking, WebSVN or any of that stuff.
Thanks,

I've never had a problem writing a data access layer, but I'm wondering if this type of product will really save the time it claims. I also worry that I will be giving up too much control over the database and make it harder to track down any data level problems. Do these type of products make it better or worse in the already tough case that the database and business object structure must change?
For example:

Given ample empty cycles I can write a Perl script that would do that, the algorithm is not complex, but it needs to be done.
I would imagine there are lots of people who needed such information and solved this problem. Thus, I think there should be a readily available (open source / free) tool for that. | cvs | null | null | null | null | null | open | How to find out which tags cover which directories?

I've chosen to use hpricot because it looks great.
Anyway, _why's been nice enough to provide the following example on the [hpricot website][1]:
#!ruby
require 'hpricot'
require 'open-uri'
# load the RedHanded home page
doc = Hpricot(open("http://redhanded.hobix.com/index.html"))
# change the CSS class on links
(doc/"span.entryPermalink").set("class", "newLinks")
# remove the sidebar
(doc/"#sidebar").remove
# print the altered HTML
puts doc
Which looks simple, elegant, and easy peasey.
Works great in Ruby, but my question is: How do I break this up in rails?
I experimented with adding this all to a single controller, but couldn't think of the best way to call it in a view.
So let's say you were parsing an XML file from a web API and printing it in nice clean HTML with Hpricot.
How would you break up the activity over the models, views, and controllers, and what would you put where?

**Error 1 Build failed due to validation errors in C:\xxx\xxx.dbml. Open the file and resolve the issues in the Error List, then try rebuilding the project. C:\xxx\xxx.dbml**
I had not touched my data access layer for weeks and no adjustments had been made to the DBML file. I tried plenty of foolhardy tricks like re-creating the layout file, making copies and re-adding the existing files back to the project after restarting Visual Studio (in case of some file-level corruption); all to no avail.
I forgot to wear my Visual Studio Skills +5 talismans, so I began searching around and the only answer that I found which made sense was to reset my packages because Visual Studio was not loading an assembly correctly. After running "*devenv.exe /resetskippkgs*" I was, in fact, able to add the dbml file back to the DAL project and rebuild the solution.
I’m glad it’s fixed, but I would rather also gain a deeper understand from this experience. **Does anyone know how or why this happens in Visual Studio 2008?**

I'm writing an app that will watch for any changes in a specific directory. This directory will be flooded with thousands of files a minute each with an "almost" unique GUID. The file format is this:
GUID.dat where GUID == xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(the internal contents aren't relevant, but it's just text data)
My app will be a form that has one single text box that shows all the files that are being added and deleted in real time. Every time a new file comes in I have to update the textbox with this file, BUT I must first make sure that this semi-unique GUID is really unique, if it is, update the textbox with this new file.
When a file is removed from that directory, make sure it exists, then delete it, update textbox accordingly.
The problem is that I've been using the .NET filewatcher and it seems that there is an internal buffer that gets blown up every time the (buffersize + 1)-th file comes in. I also tried to keep an internal List in my app, and just add every single file that comes in, but do the unique-GUID check later, but no dice.
Anyone have any advice?

I have a a repeater that is bound to some data.
I bind to the ItemDataBound event, and I am attempting to programmaticly create a UserControl:
In a nutshell:
void rptrTaskList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
CCTask task = (CCTask)e.Item.DataItem;
if (task is ExecTask)
{
ExecTaskControl foo = new ExecTaskControl();
e.Item.Controls.Add(foo);
}
}
The problem is that while the binding works, the user control is not rendered to the main page.
Any ideas?

I see my current options as:<br />
- Using a class that someone else has written and tested
- Inheriting from BindingList<T>, and implementing the IBindingListView interfaces
- Write a custom collection from scratch, implementing IBindingListView and IBindingList.
Obviously, the first option is my preferred choice.

I wrote it so that the webpage would use the registry to store certain settings (connection strings, potentially volatile locations of other web services, paths in the local filesystem where certain information is stored etc...) Of course, it worked fine when testing with VStudio.NET 2005, because the user running the app has elevated privileges. However, running it on IIS I get a "Access to the registry key 'HKEY_LOCAL_MACHINE\Software' is denied.", which suggests the IIS user doesn't have read access to that part of the registry (I only do reads through the website itself, never writes).
I was like "okay, simple enough, I'll just go give that user rights to that part of the registry through regedit." The problem is, I don't see an option anywhere in regedit to change security settings... at all. Which got me thinking... I don't think I've ever actually had to change security settings for registry hives/keys before, and I don't think I know how to do it.
Half an hour of searching the web later, I haven't found any usable information on this subject. What I'm wondering is... how DO you change security rights to portions of the registry? I'm stumped, and it seems my ability to find the answer on Google is failing me utterly... and since I just signed up here, I figured I'd see if anyone here knew. =) | security | iis | registry | windows-server-2000 | null | null | open | (IIS/Win2000Pro) Granting Registry read rights to IIS user?
