  • How to add the UAC shield icon to program that still must target XP?

    - by bsruth
    I have a program that still must target Windows XP (_WIN32_WINNT 0x501), as most of our customers still use XP. However, we have been shipping Vista for a while, and are now pushing Windows 7 upgrades. For the software to work correctly on the newer OSs, there are a couple operations that require UAC elevation. I have the elevation code working, but would like to have the UAC icon present on the buttons that launch the UAC process. Unfortunately, all of the options defined in Microsoft's UAC UI document require _WIN32_WINNT 0x600 or newer. Is there any way to get the appropriate UAC icon (Vista and 7 use different ones) to show on the button while still being able to target XP (where no icon will be shown)? I'm using C++, but may be able to adapt a .NET solution.

  • What's a good way to add a large number of small floats together?

    - by splicer
    Say you have 100000000 32-bit floating point values in an array, and each of these floats has a value between 0.0 and 1.0. If you tried to sum them all up like this result = 0.0; for (i = 0; i < 100000000; i++) { result += array[i]; } you'd run into problems as result gets much larger than 1.0. So what are some of the ways to more accurately perform the summation?

  • How do I add an object to a binary tree based on the value of a member variable?

    - by Max
    How can I get a specific value from an object? I'm trying to get a value of an instance for eg. ListOfPpl newListOfPpl = new ListOfPpl(id, name, age); Object item = newListOfPpl; How can I get a value of name from an Object item?? Even if it is easy or does not interest you can anyone help me?? Edited: I was trying to build a binary tree contains the node of ListOfPpl, and need to sort it in the lexicographic. Here's my code for insertion on the node. Any clue?? public void insert(Object item){ Node current = root; Node follow = null; if(!isEmpty()){ root = new Node(item, null, null); return; }boolean left = false, right = false; while(current != null){ follow = current; left = false; right = false; //I need to compare and sort it if(item.compareTo(current.getFighter()) < 0){ current = current.getLeft(); left = true; }else { current = current.getRight(); right = true; } }if(left) follow.setLeft(new Node(item, null, null)); else follow.setRight(new Node(item, null, null)); }

  • Repository, Service or Domain object - where does logic belong?

    - by betitall
    Take this simple, contrived example: UserRepository.GetAllUsers(); UserRepository.GetUserById(); Inevitably, I will have more complex "queries", such as: //returns users where active=true, deleted=false, and confirmed = true GetActiveUsers(); I'm having trouble determining where the responsibility of the repository ends. GetActiveUsers() represents a simple "query". Does it belong in the repository? How about something that involves a bit of logic, such as: //activate the user, set the activationCode to "used", etc. ActivateUser(string activationCode);

  • How can I add floats together in different orders, and always get the same total?

    - by splicer
    Let's say I have three 32-bit floating point values, a, b, and c, such that (a + b) + c != a + (b + c). Is there summation algorithm, perhaps similar to Kahan summation, that guarantees that these values can be summed in any order and always arrive at the exact same (fairly accurate) total? I'm looking for the general case (i.e. not a solution that only deals with 3 numbers). Is arbitrary precision arithmetic the only way to go? I'm dealing with very large data sets, so I'd like to avoid the overhead of using arbitrary precision arithmetic if possible. Thanks!

  • Django & custom auth backend (web service) + no database. How to save stuff in session?

    - by Infinity
    I've been searching here and there, and based on this answer I've put together what you see below. It works, but I need to put some stuff in the user's session, right there inside authenticate. How would I store acme_token in the user's session, so that it will get cleared if they logged out? class AcmeUserBackend(object): # Create a User object if not already in the database? create_unknown_user = False def get_user(self, username): return AcmeUser(id=username) def authenticate(self, username=None, password=None): """ Check the username/password and return an AcmeUser. """ acme_token = ask_another_site_about_creds(username, password) if acme_token: return AcmeUser(id=username) return None ################## from django.contrib.auth.models import User class AcmeUser(User): objects = None # we cannot really use this w/o local DB def save(self): """saving to DB disabled""" pass def get_group_permissions(self): """If you don't make your own permissions module, the default also will use the DB. Throw it away""" return [] # likewise with the other permission defs def get_and_delete_messages(self): """Messages are stored in the DB. Darn!""" return []

  • How to add "missing" columns in a column group in reporting services?

    - by Gimly
    Hello, I'm trying to create a report that displays for each months of the year the quantity of goods sold. I have a query that returns the list of goods sold for each month, it looks something like this : SELECT Seller.FirstName, Seller.LastName, SellingHistory.Month, SUM(SellingHistory.QuantitySold) FROM SellingHistory JOIN Seller on SellingHistory.SellerId = Seller.SellerId WHERE SellingHistory.Year = @Year GOUP BY Seller.FirstName, Seller.LastName, SellingHistory.Month What I want to do is display a report that has a column for each months + a total column that will display for each Seller the quantity sold in the selected month. Seller Name | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | Total What I managed to do is using a matrix and a column group (group on Month) to display the columns for existing data, if I have data from January to March, it will display the 3 first columns and the total. What I would like to do is always display all the columns. I thought about making that by adding the missing months in the SQL request, but I find that a bit weird and I'm sure there must be some "cleanest" solution as this is something that must be quite frequent. Thanks. PS: I'm using SQL Server Express 2008

  • Is there an easy way to add a secure file upload form (username, password, select file) to a website

    - by user346602
    Hi, I am very new to website design. Have an architect who wants his clients to enable his clients to upload (ftp - but don't know if http could be a better alternative?) files (plans etc.) to him, through the website I'm designing for him. I have seen similar things available on printers websites... I have seen uploadify, but it requires flash (I can only code HTML, CSS and a tiny bit of PHP), and don't think it is a secure option. I have also seen net2ftp, but don't really understand how it works. Any direction would be sincerely appreciated.

  • Are there any Visual Studio add-ins for true 'smart tabs'?

    - by Eye of Hell
    Hello. 'Smart Tabs' concept allows to automatically insert tab character for block indentation and space characters for in-block formatting. It's described here. Unfortunately, Visual Studio's 'smart tabs' option in text editor settings just indents text on enter press. Same name, completely different and near useless thing :). So, maybe someone knows of a visual studio addin that can change how 'tab' key work so it will insert tab characters and space characters according to rules mentioned above? Any hints are welcome. Update: I need it for C++. According to comments, ReSharper can do something like this, but only for Basic and C#.

    Hello everyone, I'm doing a RSS reader for a University Project. The feed urls have to be added by hand tipically with the copy/paste method, and I don't like this option because is poor for the users. My question is: can I do like in webpage http://feeds2.feedburner.com/microsiervos a list of web applications (Google Reader, Netvibes, etc.). There is a way to do so?

  • How do I tell if a bonjour service is wi fi or bluetooth?

    - by Dancreek
    I am building an app that sends information between two iPhones. The app is working great but the one problem I am having is that I have no way of telling whether bonjour is choosing wi-fi or bluetooth to make the connection. I would like to allow the user to be able to choose which they prefer. Also, is there way to programmatically tell is the device's bluetooth is on?

  • Is it possible to add .NET code (sections) to a WordPress site?

    - by Jason
    Our shop is primarily .NET but because of the lack of any really good popular .NET CMS products, we have chosen to use WordPress (and Drupal at times) for our public facing sites. I realize this is highly subjective, but it is the conclusion we came to for our purposes. One could certainly make a case for DotNetNuke and others, but that is another conversation. I would like to know if I can integrate small components into WordPress sites, primarily to do simple forms (logon, lost password, contact us, change user settings, etc...) Can I do this with an iFrame or another method that I am not thinking about?

  • How to add ease to this, with jQuery Easing plugin.

    - by user1691441
    I've asked this question previously before, and had a bit of help, but my lack of jQuery skills still didn't accomplish the job. I was wondering if anyone else could help me out with this. I've tried adding easing: "easeIn" right after the duration section, but still didn't work for me. if anyone could help me out that would be wonderful. I'm using the jquery easing plugin $(function() { function scroll(direction) { var scroll, i, positions = [], here = $(window).scrollTop(), collection = $('.part'); collection.each(function() { positions.push(parseInt($(this).offset()['top'],10)); }); for(i = 0; i < positions.length; i++) { if (direction == 'next' && positions[i] > here) { scroll = collection.get(i); break; } if (direction == 'prev' && i > 0 && positions[i] >= here) { scroll = collection.get(i-1); break; } } if (scroll) { $.scrollTo(scroll, { duration: 350 }); } return false; } $("#next,#prev").click(function() { return scroll($(this).attr('id')); }); $(".scrolltoanchor").click(function() { $.scrollTo($($(this).attr("href")), { duration: 350 }); return false; }); });
