  • Comparing two date / times to find out if 5 mins has lapsed between the two times php

    - by estern
    I need to compare two dates to show an edit link if it is within 5 mins after the post was made, in php. If after 5 mins dont show anything. $answer_post_date = get_the_time("Y-m-d"); $current_date = date("Y-m-d"); $formated_current_date = strtotime($answer_post_date); $formated_answer_post_date = strtotime($current_date); At this point i have two values: 1274414400 ($formated_current_date) 1276056000 ($formated_answer_post_date) I am not sure what to do next to check if the current date/time is ! 5 mins from answer post date. Any suggestions would be great All i really need the answer to be is a Boolean (yes/no) and if yes display the minuets left to show the link to edit.

  • .NET 2d library for circuit diagrams

    - by Dinah
    I want to draw and manipulate logic flow (as opposed to analog) circuit diagrams and I'm trying not to reinvent the wheel. Problems like positioning, line drawing, line crossing and connecting, path finding, rubberband lines, and drag & drop are also identical in flow charts, UML diagrams, or class diagrams so I started by viewing related topics via Google and Stack Overflow. However, the following requirements seemed to keep me from finding anything that quite fit: assuming a chip has an image with input and output stubs, the connecting lines would connect to the chip only in the exact spots of the I/O stubs the color of connecting lines are able to be set as per a chip's output Is there an existing .NET 2d graphics library that would be suitable for drawing circuit diagrams?

  • Elegant way to reverse order Formtastic nested objects?

    - by stephan.com
    I'm presenting a list of items to the user with a field for a new item, like this: - current_user.tasks.build - semantic_form_for current_user do |f| - f.semantic_fields_for :tasks do |t| - t.inputs do = t.input :_destroy, :as => :boolean, :label => '' - if t.object.new_record? = t.input :name, :label => false - else = t.object.name Which looks lovely and works like a charm. My only problem is I want the new record at the TOP of the list, not the bottom. Is there an elegant and easy way to do this, or am I going to have to do the new element separately, or loop through the list manually?

  • Is there a way to give a subquery an alias in Oracle 11g SQL?

    - by Matt Pascoe
    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

  • Anonymous functions in C#

    - by Maxim Gershkovich
    The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

  • How do you tell if a string contains another string in Unix shell scripting?

    - by Matt
    Hi all, I want to write a Unix shell script that will do various logic if there is a string inside of another string. For example, if I am in a certain folder, branch off. Could someone please tell me how to accomplish this? If possible I would like to make this not shell specific (i.e. not bash only) but if there's no other way I can make do with that. #!/bin/sh CURRENT_DIR=`pwd` if [ CURRENT_DIR contains "String1" ] then echo "String1 present" elif [ CURRENT_DIR contains "String1" ] then echo "String2 present" else echo "Else" fi

  • .rdlc reporting bound to Object Data Source in Three layer Application

    - by Saeedouv
    Hi, i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated... just to make things more clear here, assume the following: i have a solution with the follwoing layers, UI Reporting(has NO Employees object) just a reference Business Logic Data Access Layer(Employees--GetEmployees(), all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.

  • How to get result size from an SQL query and check size

    - by Jimmy
    Hi I'm trying to write a piece of code for a simple verification method as part of a MVC. At present the SQL is not written as a prepared statement so obviously it is at risk to a SQL injection so any help in regards to writing the SQL as a prepared statement would be really helpful. The method which is in the User model. public boolean getLoginInfo() { try { DBAccess dbAccess = new DBAccess(); String sql = "SELECT username, password FROM owner WHERE username = '" + this.username + "'AND password = '" + this.password + "';"; dbAccess.close();dbAccess.executeQuery(sql); dbAccess.close(); return true; } catch (Exception e) { return false; } } I want to get the size of the result set which is generated by the SQL query and if the size of it is 1 return true else it's false. If you need more info on the rest of the MVC just post and I'll get it up here.

  • Alternatives to Java bytecode instrumentation

    - by Rafael Regis
    I'm starting a project that will have to instrument java applications for coverage purposes (definition-usage of variables, etc). It has to add trace statements and some logic to the application and maybe remove statements. I have searched for ways of instrument Java code and what I always find is about bytecode instrumentation. My question is: It's the only way to instrument Java applications? There is any other way to do that? What are the advantages of bytecode instrumentation over the others? I'll probably use the bytecode solution, but I want to know what are the problems with the other approaches (if any) to decide precisely. Thanks!

  • Multiple Table Joins to Improve Performance?

    - by EdenMachine
    If I have a table structure like this: Transaction [TransID, ...] Document [DocID, TransID, ...] Signer [SignerID, ...] Signature [SigID, DocID, SignerID, ...] And the business logic is like this: Transactions can have multiple documents Documents can have multiple signatures And the same signer can have multiple signatures in multiple documents within the same transaction So, now to my actual question: If I wanted to find all the documents in a particular transaction, would it be better, performance-wise, if I also stored the TransID and the DocID in the Signer table as well so I have smaller joins. Otherwise, I'd have to join through the Signature Document Transaction Documents to get all the documents in the transaction for that signer. I think it's really messy to have that many relationships in the Signer table though and it doesn't seem "correct" to do it that way (also seems like an update nightmare) but I can see that it might be better performance for direct joins. Thoughts? TIA!

  • UInt32 to IntPtr

    - by ffenix
    I have the following problem: public class ListenThread : SocketInvoke { [DllImport("Ws2_32", CharSet = CharSet.Auto)] public unsafe static extern UInt32 WSAWaitForMultipleEvents(UInt32 cEvents, IntPtr hEventObject, UInt32 fWaitAll, UInt32 dwTimeout, Boolean fAlertable); public void ListenConnections(NetSharedData data) { while (true) { unsafe { if (WSAWaitForMultipleEvents((UInt32)1, data.signal, (UInt32)0, (UInt32)100, false) != WSA_WAIT_TIMEOUT) { } } } } data.signal is a UInt32 how i can cast it to IntPtr?, i try: IntPtr signal = (IntPtr)data.signal; but it doesn't work because i need a pointer to data.signal (UInt32) type and not the int value as an pointer, that will make a memory exception. An C++ example of what i need: int signal = 0; int* psignal = &signal;

  • How to skip interstitial in a django view if a user hits the back button?

    - by Jose Boveda
    I have an application with an interstitial page to hold the user while an intensive operation runs in the background (takes anywhere from 30 secs to 1 minute). Once the operation is done, the user is redirected to the results page. Once on the result page, typical user behavior is to hit the 'back' button to perform the operation on a different input set. However, the back button takes them to the interstitial, not the original form. The desired behavior is to go back to the original form, skipping the interstitial entirely. I'd like this to be default behavior if the user goes to the interstitial page from anywhere but the original form. I thought I could create this by using the @never_cache function decorator in my view for the interstitial, and logic based on request.META['HTTP_REFERER'], however the page doesn't respect these. The browser's back button still trumps this behavior. Any ideas on how to solve this issue?

  • SubProject OR SubFolder ?

    - by user300435
    I am writing an asp.net application that exposes data in 2 ways: 1 - 1 common section that all users can see 2 - a Section that displays data specific to a registered user. in this case the user can decide how it looks (through themes), and manage the data to be displayed. Of course, the logic behind is the same, appearance would be different for as user1 and user2 The questions are : What would be best using : 'http://www.site.com/User1' or 'http://user1.site.com'. knowing that in both cases i have to make the displayed pages look like a seperate site then the root domain in anycase, the pages that will be displayed and customized on the fly are located in a subfolder of the of the asp.net project (projectrootpath\personalpages). What is the best way to map the personalpages subfolder to a subdomain or a 'http://www.site.com/userX' in the address bar. i also use "~/" in the urls which in this case needs to point to the personalpages rather then the root . Any help is gretaly apreciated.

  • Good code visualization / refactoring tools for C++?

    - by Paul D.
    I've found myself coming across a lot of reasonably large, complicated codebases at work recently which I've been asked to either review or refactor or both. This can be extremely time consuming when the code is highly concurrent, makes heavy use of templates (particularly static polymorphism) and has logic that depends on callbacks/signals/condition variables/etc. Are there any good visualization tools for C++ period, and of those are there any that actually play well with "advanced" C++ features? Anything would probably be better than my approach now, which is basically pen+paper or stepping through the debugger. The debugger method can be good for following a particular code path, but isn't great for seeing the big picture you really need when doing serious refactoring. EDIT: I should mention that Visual Studio plugins aren't going to be a lot of help to me, since our stuff is mostly Linux-only.

  • A Better way? Finding ASP.NET controls, finding their id

    - by CSharp
    I have a method that finds all the controls, iterates through them, determines if they are a textbox,drop down list, etc.. retrieves their ID name, and depending on the ID name it will set a boolean statement (thus I would know if that section of the form is complete, and will email to a certain group of people) unfortunetly this is done with too many if statements and was wondering if I could get some help making this more manageable protected void getEmailGroup() { Control[] allControls = FlattenHierachy(Page); foreach (Control control in allControls) { if (control.ID != null) { if (control is TextBox) { TextBox txt = control as TextBox; if (txt.Text != "") { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } if (control is DropDownList) { DropDownList lb = control as DropDownList; if (lb.SelectedIndex != -1) { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } } } }

  • MySQL Query WHERE Including CASE or IF?

    - by handfix
    Strange problem. My Query looks like SELECT DISTINCT ID, `etcetc`, `if/elses over muliple joined tables` FROM table1 AS `t1` # some joins, eventually unrelated in that context WHERE # some standard where statements, they work/ CASE WHEN `t1`.`field` = "foo" THEN (`t1`.`anOtherField` != 123 AND `t1`.`anOtherField` != 456 AND `t1`.`anOtherOtherField` != "some String") WHEN `t1`.`field` = "bar" THEN `t1`.`aSecondOtherField` != 12345 END #ORDER BY CASE etc. Standard Stuff Apperantly MySQL returns a wrong rowcount and I think my problem is in the logic of the WHERE ... CASE statement. Maybe with the brackets? Maybe I should go for operator OR and not AND? Should my the second WHEN include brackets also, even when I only compare one field? Should I use IF and not CASE? Basically I want to exclude some rows with specific values IF theres a specific value in field foo or bar I would try that all out, but it takes a huge amount of time to complete that query... :(

  • Same address, multiple shared_ptr counters, is it forbidden by C++ standard?

    - by icando
    Suppose I have some needs to do the following (This is just some imaginative code for discussion of the C++ standard, thus I won't discuss why I design it this way, so don't bother me something like: your design is wrong.) T* ptr = new T; shared_ptr<T> p(ptr); shared_ptr<T> q(ptr, SomeDeleterThatDoesnotDeleteButDoSomeOtherStuff()); Suppose the logic guarantees that p or some of its copies lives longer than any copies of q, so practically there won't be any problem. My question is, is it forbidden by C++ standard, e.g. explicitly stated as UB by C++ standard, that different shared_ptr counters share the same address? Thanks.

  • Threading errors with Application.LoadComponent (key already exists)

    MSDN says that public static members of System.Windows.Application are thread safe. But when I try to run my app with multiple threads I get the following exception: ArgumentException: An entry with the same key already exists. at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.SortedList`2.Add(TKey key, TValue value) at System.IO.Packaging.Package.AddIfNoPrefixCollisionDetected(ValidatedPartUri partUri, PackagePart part) at System.IO.Packaging.Package.GetPartHelper(Uri partUri) at System.IO.Packaging.Package.GetPart(Uri partUri) at System.Windows.Application.GetResourceOrContentPart(Uri uri) at System.Windows.Application.LoadComponent(Uri resourceLocator, Boolean bSkipJournaledProperties) at System.Windows.Application.LoadComponent(Uri resourceLocator) The application works fine on a single thread and even on two or three. When I get up past 5 then I get the error every time. Am I doing something wrong? What can I do to fix this?

  • Loading UINavigationController subclass from a Nib

    - by Rits
    My situation is as follows: My class SettingsViewController is a subclass of UINavigationController. That class contains the logic of its rootViewController. For example, it acts as the delegate and data source for two table views in that root view controller. I have no problem setting this up programmatically. In the initializer of SettingsViewController, I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self. But I want to load that root view via a Nib. The problem is, I do not know how to connect that Nib with my SettingsViewController, how to set the delegates and data sources. The SettingsViewController is not accessible from within the Nib. 'File Owner' represents the root view controller, not the SettingsViewController. How do I access my UINavigationController subclass from within my root view controllers Nib? Thanks in advance.

  • WPF combo box, adding an all options item, when binding to an Observable Collection

    - by Joel Barsotti
    So I've got an object that has an observable collection. Most places I bind to this collection I only want the user to select a single item. But in one place I want the combobox to include an all items option. Is the way to do this simply with xaml converter? It seems like doing it in the view model would be a good idea, but it's really a lot dependency object goop to basically wire up an collection that is two objects deep for an on change event, where as the xaml converter just works. But I always feel like xaml converters should be generic and reusable, where in this instance, the xaml converter would be more of a one off. Of course the third option would be to create one off list for UI in the object that contains the standard observable collection. But this seems to be mixing the logic and presentation in a way that makes me uncomfortable.

I need it to be able to work with LINQ, because I want to add additional where clauses to the final query that gets run. I am looking for the best open source .NET search engine that works with LINQ. I like lucene.net but the problem is the LINQ interface (LINQ to Lucene) hasn't been updated since 2008. Are there any good options out there?
