  • How to center DIV in DIV?

    - by Lukas
    I'd like to ask you if anyone know how to horizontally center DIV in DIV with CSS ( if it's possible at all ). Outer DIV has 100%: <div id="outer" style="width:100%"> <div id="inner">Foo foo</div> </div> I've been searching for the solution for some time but I haven't found it anywhere yet...

  • Best Practice: Legitimate Cross-Site Scripting

    - by Ryan
    While cross-site scripting is generally regarded as negative, I've run into several situations where it's necessary. I was recently working within the confines of a very limiting content management system. I needed to include database code within the page, but the hosting server didn't have anything usable available. I set up a couple barebones scripts on my own server, originally thinking that I could use AJAX to import the contents of my scripts directly into the template of the CMS (thus retaining dynamic images, menu items, CSS, etc.). I was wrong. Due to the limitations of XMLHttpRequest objects, it's not possible to grab content from a different domain. So I thought "iFrame" - even though I'm not a fan of frames, I thought that I could create a frame that matched the width and height of the content, so that it would appear native. Again, I was blocked by cross-site scripting "protections." While I could indeed load a remote file into the iFrame, I couldn't execute JavaScript to modify its size on either the host page or inside the loaded page. In this particular scenario, I wasn't able to point a subdomain to my server. I also couldn't create a script on the CMS server that could proxy content from my server, so my last thought was to use a remote JavaScript. A remote JavaScript works. It breaks when the user has JavaScript disabled, which is a downside; but it works. The "problem" I was having with using a remote JavaScript was that I had to use the JS function document.write() to output any content. Any output that isn't JS causes script errors. In addition to using document.write() for every line, you also have to ensure that the content is escaped - or else you end up with more script errors. My solution was as follows: My script received a GET parameter ("page") and then looked for the file ({$page}.php), and read the contents into a variable. However, I had to use awkward buffering techniques in order to actually execute the included scripts (for things like database interaction) then strip the final content of all line break characters ("\n") followed by escaping all required characters. The end result is that my original script (which outputs JavaScript) accesses seemingly "standard" scripts on my server and converts their standard output to JavaScript for displaying within the CMS template. While this solution works, it seems like there may be a better way to accomplish the same thing. What is the best way to make cross-site scripting work specifically for the purpose of including content from a completely different domain?

  • Containers of reference_wrappers (comparison operators required?)

    - by kloffy
    If you use stl containers together with reference_wrappers of POD types, the following code works just fine: int i = 3; std::vector< boost::reference_wrapper<int> > is; is.push_back(boost::ref(i)); std::cout << (std::find(is.begin(),is.end(),i)!=is.end()) << std::endl; However, if you use non-POD types such as (contrived example): struct Integer { int value; bool operator==(const Integer& rhs) const { return value==rhs.value; } bool operator!=(const Integer& rhs) const { return !(*this == rhs); } }; It doesn't suffice to declare those comparison operators, instead you have to declare: bool operator==(const boost::reference_wrapper<Integer>& lhs, const Integer& rhs) { return boost::unwrap_ref(lhs)==rhs; } And possibly also: bool operator==(const Integer& lhs, const boost::reference_wrapper<Integer>& rhs) { return lhs==boost::unwrap_ref(rhs); } In order to get the equivalent code to work: Integer j = { 0 }; std::vector< boost::reference_wrapper<Integer> > js; js.push_back(boost::ref(j)); std::cout << (std::find(js.begin(),js.end(),j)!=js.end()) << std::endl; Now, I'm wondering if this is really the way it's meant to be done, since it seems impractical. It just seems there should be a simpler solution, e.g. templates: template<class T> bool operator==(const boost::reference_wrapper<T>& lhs, const T& rhs) { return boost::unwrap_ref(lhs)==rhs; } template<class T> bool operator==(const T& lhs, const boost::reference_wrapper<T>& rhs) { return lhs==boost::unwrap_ref(rhs); } There's probably a good reason why reference_wrapper behaves the way it does (possibly to accomodate non-POD types without comparison operators?). Maybe there already is an elegant solution and I just haven't found it.

  • maximum stored proc name in firebird

    - by Crudler
    Hi, I am migrating my db from Interbase to Firebird, and the 1st hiccup we hit comes from our stored proc names. We have a handful of stored procedures with names greater than 31 characters (which appears to be the max in FB 2.1.3) Is there a way to increase this limitation? It will be a far easier solution than modifying our software. Thanks!

  • Creating a byte array from a stream

    - by Bob
    What is the preffered method for creating a byte array from an input stream? Here is my current solution with .NET 3.5. Is it still a better idea to read and write chunks of the stream? Stream s; byte[] b; using (BinaryReader br = new BinaryReader(s)) { b = br.ReadBytes(s.Length); }

  • struts 2 - where should I set global application variables?

    - by Nicola Montecchio
    Hi I'm using struts 2 and I'd like to read some custom-defined parameters (global variables), preferably from web.xml or some custom ".properties" file (i.e. not hardcoded in the Java sources). This problem has been driving me mad for the past half hour as I can't google any reasonable solution. What is the best way to do this? I find it strange that it is so difficult ... all the best Nicola Montecchio

  • Control.IsAccessible

    - by Gerhard
    I need to check if a c# WinForm Window (FORM Class) has been initialized and waiting for user events. But I could not find out how to manage that. Therefore I had the idea to set the Control.IsAccessible Flag of the Form to true, within the OnLoad Event of the Windows Form. My question is now, what is the Control.IsAccessible Flag origin intended for? Or is there an other solution to check if the Winform is initialized. Thanks for your help

  • Prevent command "del /s" from entering a folder

    - by jzuniga
    I need to recursively remove unnecessary files from a svn repository and i have the following batch file to do this: @echo on del /s ~*.* del /s *.~* del /s Thumbs.db However, this is also deleting the entries under the .svn/ subfolders. Is there any way to prevent this commands from being executed under the .svn/ folders so that it doesn't mess things up? Thanks in advance! EDIT: A solution using Bash (cygwin) would also work for me since i just need to do this once.

  • Building a regexp to split a string

    - by Kivin
    I'm seeking a solution to splitting a string which contains text in the following format: "abcd efgh 'ijklm no pqrs' tuv" which will produce the following results: ['abcd', 'efgh', 'ijklm no pqrs', 'tuv'] In otherwords, it splits by whitespace unless inside of a single quoted string. I think it could be done with .NET regexps using "Lookaround" operators, particularly balancing operators. I'm not so sure about perl.

  • NHibernate (3.1.0.4000) NullReferenceException using Query<> and NHibernate Facility

    - by TigerShark
    I have a problem with NHibernate, I can't seem to find any solution for. In my project I have a simple entity (Batch), but whenever I try and run the following test, I get an exception. I've triede a couple of different ways to perform a similar query, but almost identical exception for all (it differs in which LINQ method being executed). The first test: [Test] public void QueryLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .FirstOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.FirstOrDefault(IQueryable`1 source) The second test: [Test] public void QueryLatestBatch2() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .OrderBy(x => x.Executed) .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.SingleOrDefault(IQueryable`1 source) However, this one is passing (using QueryOver<): [Test] public void QueryOverLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.QueryOver<Batch>() .OrderBy(x => x.Executed).Asc .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); Assert.That(batch.Executed, Is.LessThan(DateTime.Now)); } } Using the QueryOver< API is not bad at all, but I'm just kind of baffled that the Query< API isn't working, which is kind of sad, since the First() operation is very concise, and our developers really enjoy LINQ. I really hope there is a solution to this, as it seems strange if these methods are failing such a simple test. EDIT I'm using Oracle 11g, my mappings are done with FluentNHibernate registered through Castle Windsor with the NHibernate Facility. As I wrote, the odd thing is that the query works perfectly with the QueryOver< API, but not through LINQ.

  • Using a visual tool to view changes on git repository

    - by Phuong Nguy?n
    I'm coming to an existing project in which people used git to track everything from scratch. I want to have a tool to view the differences between several commits. gitk does a good job, but talking about human readability, it's does not facilitate me much. Is there a better solution? I'm looking for a set of tools that allow me to easily compare branches (some how like winmerge - Display two version in parallel and highlight the changes), and running on Mac.

  • Any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files?

    - by Malcolm
    Are there any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files? The reason I'm asking is that I frequently use a custom PY2EXE script that UPX's copies of these files on every build. Yes, I could get fancy and try to cache UPXed files, but I think a simpler, safer, and higher performance solution would be for me to just UPX my Python 2.6.4 directory once and be done with it. Thoughts? Malcolm

  • MySQL to fill in missing dates when using GROUP BY DATE(table.timestamp) without joining on temporar

    - by twmulloy
    Hello, after reading through a couple similar Qs/As I haven't quite found the solution I'm looking for. The table data I have is GROUP BY DATE(timestamp) and returning a count, example result: [timestamp] = 2010-05-12 20:18:36 [count] = 10 [timestamp] = 2010-05-14 10:10:10 [count] = 8 Without using a temporary table, or calendar table is there a way to fill in those missing dates? so that with the same table data would return (adding the bold row): [timestamp] = 2010-05-12 20:18:36 [count] = 10 [timestamp] = 2010-05-13 00:00:00 [count] = 0 [timestamp] = 2010-05-14 10:10:10 [count] = 8 Thanks!

  • Why does ASP.Net rewrite relative paths in runat=server anchor controls?

    - by Atomiton
    I have UserControls in a Controls folder in my solution: /Controls/TheControl.ascx If specify the following: <a runat="server" href="./?pg=1">link text</a> ASP.Net seems to want to rewrite the path to point to the absolute location. For example, If the control is on site.com/products/fish/cans.aspx the link href will be rewritten to read <a href="../../Controls/?pg=1 Why does Asp.Net rewrite these control paths, and is there an elegant way to fix it?
