  • Can a .csv file be used as a data source in Visual Studio 2008 (C#)?

    - by Kevin
    I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a MS SQL database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data.

  • What does it mean whether network device is Loopback?

    - by Gtker
    Does it mean that the Loopback device handles the request like ping localhost ? If so, there should be at least one device that's loopback,but seems none of my two network device is Loopback: rpcap://\Device\NPF_{45D5ADA0-095E-49F3-BEA1-E8754390F2D4} Description: Network adapter 'Intel(R) PRO/Wireless 2200BG Network Conne ction (Microsoft's Packet Scheduler) ' on local host Loopback: no rpcap://\Device\NPF_{783C5467-4026-473C-86A0-5E5A3708C624} Description: Network adapter 'Realtek RTL8169/8110 Family Gigabit Ethern et NIC (Microsoft's Packet Scheduler) ' on local host Loopback: no Can someone clarify all this?

  • Make a jqGrid moveable

    - by Dave
    As it appears that jqGrid is based on the jQuery dialog, is it possible to make it movable (like a dialog)? I've been able to put it inside of a dialog but it looks odd with two title bars and such. I'd "think" that the necessary class could be added to it to make it movable but I'm still fairly new at both jQuery and jqGrid.

  • Consequences of isRouteDisplayed() on map view

    - by poeschlorn
    Hi guys, I'm just wondering what consequences the method isRouteDisplayed() has, regarding to functionality of a map view... I have two activities, one displays a route and one doesn't. Is it mandatory to let the first isRouteDisplayed()-Method return true? What effects does it have? greets, poeschlorn

  • The difference between lists and sequences

    - by Peanut
    I'm trying to understand the difference between sequences and lists. In F# there is a clear distinction between the two. However in C# I have seen programmers refer to IEnumerable collections as a sequence. Is what makes IEnumerable a sequence the fact that it returns an object to iterate through the collection? Perhaps the real distinction is purely found in functional languages?

  • Listing defined functions in bash

    - by Charles Duffy
    I'm trying to write some code in bash which uses introspection to select the appropriate function to call. Determining the candidates requires knowing which functions are defined. It's easy to list defined variables in bash using only parameter expansion: $ prefix_foo="one" $ prefix_bar="two" $ echo "${!prefix_*}" prefix_bar prefix_foo However, doing this for functions appears to require filtering the output of set -- a much more haphazard approach. Is there a Right Way?

  • Export list as .txt (Python)

    - by Nimbuz
    My Python module has a list that contains all the data I want to save as a .txt file somewhere. The list contains several tuples like so: list = [ ('one', 'two', 'three'), ('four', 'five', 'six')] How do I print the list so each tuple item is separated by a tab and each tuple is separated by a newline? Thanks

  • Can I have a macro in Visual Studio 2005 call a DOS command and redirect the output to a file?

    - by Mark
    I'd like to have a macro in Visual Studio 2005 that calls a DOS command and redirects the output (stdout and stderr) to a file. Just calling the command and "" redirecting it will not capture stderr, so there are two parts to this: calling a DOS command capturing both stderr and stdout to a file during that call I'd then like to open this file in Visual Studio after the command completes. I'm new to Visual Studio 2005 macro writing, and VB/VBA, so that's the kind of help that I'm looking for. Thanks, Mark

  • C++ enum in foreach

    - by Spencer
    I've have a card class for a blackjack game with the following enums: enum Rank { Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King }; enum Suit { Clubs, Diamonds, Hearts, Spades }; When I create the deck I want to write the code like this: // foreach Suit in Card::Suit // foreach Rank in Card::Rank // add new card(rank, suit) to deck I believe there is no foreach in c++. However, how do I traverse an enum? Thanks, Spencer

  • ASP.NET MVC users - do you miss anything from WebForms?

    - by Richard Ev
    There are lots of articles and discussions about the differences between ASP.NET WebForms and ASP.NET MVC that compare the relative merits of the two frameworks. I have a different question for anyone who has experience using WebForms that has since moved to MVC: What is the number one thing that WebForms had, that MVC doesn't, that you really miss? Edit No-one has mentioned the WebForms validation controls. I am now working on some code that has a few dependant validation rules and implementing client-side validation for these is proving slow.

  • Will methods like POST and GET formally evolve someday?

    - by Jorge
    The question may sound a bit naive or stupid, but i was wondering...will POST and GET evolve someday? What other methods exist besides those two? I was wondering specifically about server-pushes... why can't exist a method specifically for that? I don't even know if there's already something similar, and if there is, i apologize for my ignorance. The web is evolving, that's evident...will methods formally evolve too?

  • SharePoint weekly summary alert with calculated columns

    - by Geoff
    I have a SharePoint list that accepts incoming email and has two calculated columns based on the Email Subject. Immediate alerts, RSS etc all work fine but the Weekly Summary Alert has #VALUE! for all the calculated columns. Is there a reason for this? Can I get it to show that actual calculated value?

  • What is your favourite cleverly written functional code?

    - by sdcvvc
    What are your favourite short, mind-blowing snippets in functional languages? My two favourite ones are (Haskell): powerset = filterM (const [True, False]) foldl f v xs = foldr (\x g a -> g (f a x)) id xs v -- from Hutton's tutorial (I tagged the question as Haskell, but examples in all languages - including non-FP ones - are welcome as long as they are in functional spirit.)

  • How can I determine a file extension given a file path in LaTeX?

    - by Frank
    I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  • Finding what makes strings unique in a list, can you improve on brute force?

    - by Ed Guiness
    Suppose I have a list of strings where each string is exactly 4 characters long and unique within the list. For each of these strings I want to identify the position of the characters within the string that make the string unique. So for a list of three strings abcd abcc bbcb For the first string I want to identify the character in 4th position d since d does not appear in the 4th position in any other string. For the second string I want to identify the character in 4th position c. For the third string it I want to identify the character in 1st position b AND the character in 4th position, also b. This could be concisely represented as abcd -> ...d abcc -> ...c bbcb -> b..b If you consider the same problem but with a list of binary numbers 0101 0011 1111 Then the result I want would be 0101 -> ..0. 0011 -> .0.. 1111 -> 1... Staying with the binary theme I can use XOR to identify which bits are unique within two binary numbers since 0101 ^ 0011 = 0110 which I can interpret as meaning that in this case the 2nd and 3rd bits (reading left to right) are unique between these two binary numbers. This technique might be a red herring unless somehow it can be extended to the larger list. A brute-force approach would be to look at each string in turn, and for each string to iterate through vertical slices of the remainder of the strings in the list. So for the list abcd abcc bbcb I would start with abcd and iterate through vertical slices of abcc bbcb where these vertical slices would be a | b | c | c b | b | c | b or in list form, "ab", "bb", "cc", "cb". This would result in four comparisons a : ab -> . (a is not unique) b : bb -> . (b is not unique) c : cc -> . (c is not unique) d : cb -> d (d is unique) or concisely abcd -> ...d Maybe it's wishful thinking, but I have a feeling that there should be an elegant and general solution that would apply to an arbitrarily large list of strings (or binary numbers). But if there is I haven't yet been able to see it. I hope to use this algorithm to to derive minimal signatures from a collection of unique images (bitmaps) in order to efficiently identify those images at a future time. If future efficiency wasn't a concern I would use a simple hash of each image. Can you improve on brute force?

    Hy everybody, I have two targets in one Project in Xcode. One is a foundation tool which i need in the resources Bin of the other Target, which is a Bundle App. I am not able to add the Target one into the Copy Bundle Resources Build Phase of the Bundle App. Do I need to use a Copy Files Build phase and put the File out of the build/Release Folder into it?

  • Ignore SSL errors in Zend_Http_Client

    - by webdestroya
    In PHP curl there are two functions used to ignore all SSL errors (invalid cert, self signed, expired, so on): curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); I am switching over to use Zend_Http_Client, but I can't seem to find a way to force it to ignore errors. (I don't have a way to test it just yet, I wanted to see if anybody has done this before) So, does anybody know the equivalent function/functions to do this in Zend_Http_Client?
