  • Variable number of arguments in ParamArray ArgList()

    - by Excel VBA guy
    If I want to pass a number of values for the ParamArray arglist via an array, how do I do it? From what I've read so far, on VBA, it appears that I need to explicitly list the values that I want to pass. But what if there are potentially different numbers of values to pass, so I do not know in advance how many I'll want to pass to the function? Is there not some way of using an array (a one-dimensional array) with a variable dimension?

  • Set secondary receiver in PayPal Chained Payment after the initial transaction

    - by CJxD
    I'm running a service whereby customers seek the services of 'freelancers' through our web platform. The customer will make a 'bid' which is immediately taken from their accounts as security. Once the job is completed, the customer marks it as accepted and the bid gets distributed to the freelancer(s) as a reward. After initially storing these rewards in the accounts of the freelancers and relying on MassPay to sort out paying them later, I realised that your business needs to be turning over at least £5000/month before MassPay is switched on. Instead, I was referred to Delayed Chained Payments in PayPal's Adaptive Payments API. This allows the customer to pay the primary receiver (my business) before the payment is later triggered to be sent to the secondary receivers (the freelancers). However, at the time that the customer initiates this transaction, you must understand that nobody yet knows who will receive the reward. So, before I program this whole Adaptive Payments system, is it even possible to change or add the secondary receivers after the customer has paid? If not, what can I do?

  • Windows Process : Tool to see Function and change arguments

    - by Jayan
    Sometime back I used a windows tool to see what a process is doing. This tool allowed me to inspect functions exported from DLL. It also allowed me to change the values passed to a function on the fly. I cannot recollect the name(not sure if that was free or commercial one). Could any one point to me solution that can do this? (Tools like ProcessExplorer, ProcessMonitor helps a bit.. this was better) Cheers, Jayan

  • Separate urls for a set of pages sharing 80% duplicate content

    - by user131003
    Issue: Currently my site has one particular page which has country specific data. So I've URLs like : mysite.com/sale-united-states mysite.com/sale-united-kingdom mysite.com/sale-sweden etc. All these pages have 80-90% common content and 10-20% country specific content. currently all these pages canonically point to mysite.com/sale-united-states. The problem is when someone searches for "sale Sweden", Google correctly shows mysite.com/sale-united-states page, which does not feel correct as it shows US page instead of Sweden. Now I'm thinking of not using canonical url so that country specific urls are produced in Google saerch. But I'm not sure how 80% duplicate content is going to affect SEO? What should be the recommended approach for this situation? A friend of mine suggested a "separate subdomain per country" based approach but it seems overkill for one page.

  • How to Find Your Lost Android Phone, Even if You Never Set Up a Tracking App

    - by Chris Hoffman
    Android doesn’t come with a “find my Android” feature, so there’s no official way to track your phone if you lose it. You should prepare your phone for loss by setting up such a tracking app — but what if you didn’t? Your first instinct may be to download Lookout’s Plan B, which has been the go-to app for this purpose. However, Plan B only runs on Android 2.3 Gingerbread and lower, so modern Android phones will require a new solution. If you are still running 2.3 or lower, you should definitely check it out, but everybody else can keep reading.

  • Contains performs MUCH slower with variable vs constant string MS SQL Server

    - by Greg R
    For some unknown reason I'm running into a problem when passing a variable to a full text search stored procedure performs many times slower than executing the same statement with a constant value. Any idea why and how can that be avoided? This executes very fast: SELECT * FROM table WHERE CONTAINS (comments, '123') This executes very slowly and times out: DECLARE @SearchTerm nvarchar(30) SET @SearchTerm = '123' SET @SearchTerm = '"' + @SearchTerm + '"' SELECT * FROM table WHERE CONTAINS (comments, @SearchTerm) Does this make any sense???

  • Using Python to traverse a parent-child data set

    - by user132748
    I have a dataset of two columns in a csv file. Th purpose of this dataset is to provide a linking between two different id's if they belong to the same person. e.g (2,3,5 belong to 1) e.g COLA COLB 1 2 ; 1 3 ; 1 5 ; 2 6 ; 3 7 ; 9 10 In the above example 1 is linked to 2,3,5 and 2 is the linked to 6 and 3 is linked to 7. What I am trying to achieve is to identify all records which are linked to 1 directly (2,3,5) or indirectly(6,7) and be able to say that these id's in column B belong to same person in column A and then either dedupe or add a new column to the output file which will have 1 populated for all rows that link to 1 e.g of expected output colA colB GroupField 1 2 1; 1 3 1; 1 5 1 ; 2 6 1 ;3 7 1; 9 10 9; 10 11 9 I am a newbie and so am not sure on how to approach this problem.Appreciate any inputs you'll can provide.

  • Subdomain still times out after set up a month ago

    - by user8137
    I'm a newbie on this and this has probably been asked already but the subjects online were close but too vague in there answers so I've probably really messed this up. I would really appreciate specific step by step instructions. This is what I'd like to do: use the subdomain www.high-res.domain.com to be accessed by external customers with specific permissions to access the site (like ftp). We use Network Solutions to house domain.com. We recently added a new ip address to point to www.high-res.domain.com. I gave the ip address to the company that hosts our website. I pinged www.high-res.domain.com and it points to the correct ip address but still times out. It’s been a few weeks now and when you ping it, it still times out. C:ping XXX.XXX.X.XXX Pinging XXX.XXX.X.XXX with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for XXX.XXX.X.XXX: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss). Tracert times out as well. I even went to DNS tools and a few other sites for checking this and it shows the same thing. I recently went into the DNSmgmt on our server (wink2k3sp1) and created an A record under the DomainDnsZones which translated to a Cname when you look at it. Under the Domain it has two entries one to the subdomain and the other to the website host each with separate ip addresses. Is this correct? The website people are too busy on another project to research it further and my friends haven't gotten back to me. Please help. Thanks KK

  • How do you accept arguments in the main.cpp file and reference another file?

    - by Jason H.
    I have a basic understanding of programming and I currently learning C++. I'm in the beginning phases of building my own CLI program for ubuntu. However, I have hit a few snags and I was wondering if I could get some clarification. The program I am working on is called "sat" and will be available via command line only. I have the main.cpp. However, my real question is more of a "best practices" for programming/organization. When my program "sat" is invoked I want it to take additional arguments. Here is an example: > sat task subtask I'm not sure if the task should be in its own task.cpp file for better organization or if it should be a function in the main.cpp? If the task should be in its own file how do you accept arguments in the main.cpp file and reference the other file? Any thoughts on which method is preferred and reference material to backup the reasoning?

  • What arguments to use to explain why SQL Server is far better then a flat file

    - by jamone
    The higher ups in my company were told by good friends that flat files are the way to go, and we should switch from SQL Server to them for everything we do. We have over 300 servers and hundreds of different databases. From just the few I'm involved with we have 10 billion records in quite a few of them with upwards of 100k new records a day and who knows how many updates... Me and a couple others need to come up with a response saying why we shouldn't do this. Most of our stuff is ASP.NET with some legacy ASP. We thought that making a simple console app that tests/times the same interactions between a flat file (stored on the network) and SQL over the network doing large inserts, searches, updates etc along with things like network disconnects randomly. This would show them how bad flat files can be especially when you are dealing with millions of records. What things should I use in my response? What should I do with my demo code to illustrate this? My sort list so far: Security Concurrent access Performance with large amounts of data Amount of time to do such a massive rewrite/switch Lack of transactions PITA to map relational data to flat files NTFS doesn't support tons of files in a directory well I fear that this will be a great post on the Daily WTF someday if I can't stop it now.

  • redefine shortcuts for keys being set to default after reboot

    - by MYA
    i am using PHPStorm editor on Ubuntu 14.04. Everything is so smooth that I am loving the experience (especially the workspace experience is amazing) however this bug is giving me headache... some of the editor's short-cuts clash with default Ubuntu keys (Alt + Ctrl + Left,Right,Up or Down arrow keys). I have changed the default keys to (super + Left,Right,Up and Down arrow keys) so they don't collide with my editor but after the reboot, Ubuntu changes are somehow reverting to default. This keeps comming again and again. i am sure there is a way out so therefore need help with that...

  • Concatenate 2 text elements on a line with full-width border using CSS only

    - by Michael Horne
    Okay, I'm a newbie to CSS3, so please be gentle. ;-) I'm working with some Wordpress code (Woocommerce plugin, to be exact), and I'm trying to format a line of code in a sidebar so that 2 separate text items (one in an <a, the other in a <span are all on the same line, the full width of the column, and with a bottom border. It looks something like this (except the bottom border on each text do not go all the way across the enclosing sidebar box): http://www.dalluva.com/temp/browse-catalog.JPG (sorry, I'm new and can't post inline images yet) Here's the code fragment I'm trying to live with (i.e. I don't want to change it): <div class="widget"> ... <ul class="product-categories"> <li class="cat-item"> <a href="http://localhost/dalluva/shop/product-category/books/">Books</a> <span class="count">(5)</span> </li> ... And here's the CSS I have now: .widget ul li a { border-bottom: 1px solid #e9e9e9; line-height:1.0; padding: 5px 0 5px 22px; display: inline-block; } .widget ul li span { border-bottom: 1px solid #e9e9e9; line-height: 1.0; padding: 5px 0 5px 0; display: inline-block; } The output in the image above looks right for this CSS code, but when I change the 'span' CSS to include a width:100%, it causes the span element to wrap to the next line, looking like this: http://www.dalluva.com/temp/browse-catalog-2.JPG I've played with white-space:nowrap, overflow:hidden, etc, but I can't seem to find a way to have both the <a and the <span text on the same line with the border extending the full width of the column. Any suggestions on getting the desired effect through CSS only? Thanks. Michael

  • Passing arguments to an Rspec SpecTask

    - by Bayard Randel
    Rake allows for the following syntax: task :my_task, :arg1, :arg2 do |t, args| puts "Args were: #{args}" end I'd like to be able to do the same, but with RSpecs SpecTask. The following unfortunately fails: desc "Run example with argument" SpecTask.new('my_task'), :datafile do |t, args| t.spec_files = FileList['cvd*_spec.rb -datafile=#{args}'] t.spec_opts = ["-c -f specdoc"] end Is it possible to achieve this with a SpecTask, or is there an alternative approach?

  • C#: Preferred pattern for functions requiring arguments that implement two interfaces

    - by JS Bangs
    The argument to my function f() must implement two different interfaces that are not related to each other by inheritance, IFoo and IBar. I know of two different ways of doing this. The first is to declare an empty interface that inherits from both: public interface IFooBar : IFoo, IBar { // nothing to see here } public int f(IFooBar arg) { // etc. } This, of course, requires that the classes declare themselves as implementing IFooBar rather than IFoo and IBar separately. The second way is to make f() generic with a constraint: public int f<T>(T arg) where T : IFoo, IBar { // etc. } Which of these do you prefer, and why? Are there any non-obvious advantages or disadvantages to each?

  • Rotate camera around player and set new forward directions

    - by Samurai Fox
    I have a 3rd person camera which can rotate around the player. When I look at the back of the player and press forward, player goes forward. Then I rotate 360 around the player and "forward direction" is tilted for 90 degrees. So every 360 turn there is 90 degrees of direction change. For example when camera is facing the right side of the player, when I press button to move forward, I want player to turn to the left and make that the "new forward". I have Player object with Camera as child object. Camera object has Camera script. Inside Camera script there are Player and Camera classes. Player object itself, has Input Controller. Also I'm making this script for joystick/ controller primarily. My camera script so far: using UnityEngine; using System.Collections; public class CameraScript : MonoBehaviour { public GameObject Target; public float RotateSpeed = 10, FollowDistance = 20, FollowHeight = 10; float RotateSpeedPerTime, DesiredRotationAngle, DesiredHeight, CurrentRotationAngle, CurrentHeight, Yaw, Pitch; Quaternion CurrentRotation; void LateUpdate() { RotateSpeedPerTime = RotateSpeed * Time.deltaTime; DesiredRotationAngle = Target.transform.eulerAngles.y; DesiredHeight = Target.transform.position.y + FollowHeight; CurrentRotationAngle = transform.eulerAngles.y; CurrentHeight = transform.position.y; CurrentRotationAngle = Mathf.LerpAngle(CurrentRotationAngle, DesiredRotationAngle, 0); CurrentHeight = Mathf.Lerp(CurrentHeight, DesiredHeight, 0); CurrentRotation = Quaternion.Euler(0, CurrentRotationAngle, 0); transform.position = Target.transform.position; transform.position -= CurrentRotation * Vector3.forward * FollowDistance; transform.position = new Vector3(transform.position.x, CurrentHeight, transform.position.z); Yaw = Input.GetAxis("Right Horizontal") * RotateSpeedPerTime; Pitch = Input.GetAxis("Right Vertical") * RotateSpeedPerTime; transform.Translate(new Vector3(Yaw, -Pitch, 0)); transform.position = new Vector3(transform.position.x, transform.position.y, transform.position.z); transform.LookAt(Target.transform); } }

  • Doing affiliate program with shops who don't have a program already set up

    - by Jacobo Polavieja
    I am developing an online shop which has managed to agree with other shops to a comission per sale. Now, the problem, is these other shops don't have any kind of affiliate system. So my question is, is there any way we could arrange an easy way for this? They don't plan to develop anything as they are small shops, so... my only guess right now is to control on my site how many times the links to them have been clicked to have an estimate of potential clients, but don't know how they can know that user came through my site and purchased something. Thank you very much for your help!

  • How can I change or remove HttpRequest input arguments in a HttpModule

    - by Eric Gunn
    Is it possible to change or remove http request form inputs in an httpmodule? My goal is to create a security IHttpmodule that will check the request for reasonable values, such as limits on acceptable input and query parameter length, or use the AntiXSS Sanitizer to remove threats, log potential hack attempts, etc. before a request is passed on to a processor. Because this is a cross cutting concern I'd prefer to find a solution that applies to all requests and affects all ways request values could be accessed, Reqest.Form, Action(model), Action(FormCollection), HttpContext.Current.Request.Form, etc. I'm using MVC and have considered creating custom model binders to clean the data before creating the model instance. But that would be application specific, require remembering to register every model binder and only apply to Action(model).
