  • New to C# and trying to use a global variable

    - by Andrew G. Johnson
    Is it possible to use global variables in C#? I'm coming from mainly a PHP background so variables are either accessible everywhere or just a global definition away. My main issue is I have a User class that I built myself to wrap around the current users table on my company's database. I am defining it in the MasterPage but can't seem to access it from the actual pages (I don't know if there's a better word to describe them but they are the pages that inherit the styles and format from the MasterPage) Any general tips or implementation practices for me? EDIT: here's some code snippets of what I'm trying to do: Site.master.cs public partial class SiteMaster : System.Web.UI.MasterPage { public User user = new User(); } logout.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="logout.aspx.cs" Inherits="logout" %> <%@ MasterType virtualPath="~/Site.master"%> logout.aspx.cs public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { User user = Master.user; } }

  • iOS Facebook Access Token To Get User Wall Feed (status)

    - by Felix
    [DISCLAIMER : None of the access token or ID below here are real] I've done research for three solid days and no result on how to get user wall feed(post). I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

  • Different kinds of doubles in vb.net?

    - by Jonathan
    Hey all- I'm using QBFC to generate invoices in a Quickbooks integrating app. I'm getting an exception thrown for lineItem.Amount.SetValue(val as Double) when I try to enter a programmatically generated double. The following does not work: lineItem = invoice.ORInvoiceLineAddList.Append.InvoiceLineAdd Dim amount as Double amount = summary.dailySold * summary.dailyRate loggingTxtBox.AppendText("Amount is " & amount & vbNewLine) lineItem.Amount.SetValue(amount) The exception I receive is System.Runtime.InteropServices.COMException (0x80040305): Invalid Amount format. at Interop.QBFC8.IQBAmountType.SetValue(Double val) The following works: lineItem.Amount.SetValue(20.3) Any suggestions? Is .NET interpretting a hard-coded double differently than a programmatically calculated one? Thanks- Jonathan

  • Scrapy Not Returning Additonal Info from Scraped Link in Item via Request Callback

    - by zoonosis
    Basically the code below scrapes the first 5 items of a table. One of the fields is another href and clicking on that href provides more info which I want to collect and add to the original item. So parse is supposed to pass the semi populated item to parse_next_page which then scrapes the next bit and should return the completed item back to parse Running the code below only returns the info collected in parse If I change the return items to return request I get a completed item with all 3 "things" but I only get 1 of the rows, not all 5. Im sure its something simple, I just can't see it. class ThingSpider(BaseSpider): name = "thing" allowed_domains = ["somepage.com"] start_urls = [ "http://www.somepage.com" ] def parse(self, response): hxs = HtmlXPathSelector(response) items = [] for x in range (1,6): item = ScrapyItem() str_selector = '//tr[@name="row{0}"]'.format(x) item['thing1'] = hxs.select(str_selector")]/a/text()').extract() item['thing2'] = hxs.select(str_selector")]/a/@href').extract() print 'hello' request = Request("www.nextpage.com", callback=self.parse_next_page,meta={'item':item}) print 'hello2' request.meta['item'] = item items.append(item) return items def parse_next_page(self, response): print 'stuff' hxs = HtmlXPathSelector(response) item = response.meta['item'] item['thing3'] = hxs.select('//div/ul/li[1]/span[2]/text()').extract() return item

  • my NSDateFormatter works only in the iPhone simulator

    - by Manuel Spuhler
    I use a NSDateFormatter which works fine in the simulator, but I get a nil when I run it in the iPhone. I hardcoded the date to be sure of the format, but it fails anyway. NSString *strPubDate = @"Fri, 8 May 2009 08:08:35 GMT"; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [dateFormatter setDateFormat:@"EEE, d MMM yyyy HH:mm:ss Z"]; NSDate *myDate = [dateFormatter dateFromString:strPubDate]; I tried with different region settings, languages etc. on the iPhone. Any idea what is going wrong?

  • Parameter passing Vs Table Valued Parameters Vs XML to SQL 2008 from .Net Application

    - by Harryboy
    As We are working on a asp .net project there three ways one can update data into database when there are multiple rows updation / insertion required Let's assume we need to update employee education detail (which could be 1,3,5 or 10 records) Method to Update Data Pass value as parameter (Traditional approach), If 10 records are there then 10 round trip required Pass data as xml and write logic inside your stored procedure to get that data from xml and update the table (only single roundtrip required) Use Table valued parameters (only single roundtrip required) Note : Data is available as List, so i need to convert it to xml or any other format if i need to pass. There are no. of places in entire application we need to update data in bulk (or multiple records) I just need your suggestions that Which method will be faster (please mention if there are some other overheads) Manageability or testability concern with any approach Any other bottleneck or issue with any of the approach (Serialization /Deserialization concern or limit on size of the data passing) Any other method you suggest for same operations Thanks

  • How do I display data in a table and allow users to copy selected data?

    - by cfouche
    Hi I have a long list of data that I want to display in table format to users. The data changes when the user performs certain actions in my app, but it is not directly editable. So the user can create a reasonably big table of data, but he can't change individual cells' values. However, I do want the data to be copy-able. So I want it to be possible for the user to select some or all of the cells, and do a ctrl-C to copy the data to his clipboard, and then a ctrl-V to paste the data to an external text editor. At the moment, I'm displaying the data in a ListView with a GridView and this works perfectly, except that GridView doesn't allow one to copy data. What other options can I try? Ours is a WPF app, coding in c#.

  • Regex to validate initials

    - by iar
    I'm looking for a regex to validate initials. The only format I want it to allow is: (a capital followed by a period), and that one or more times Valid examples: A. A.B. A.B.C. Invalid examples: a. a A A B A B C AB ABC Using The Regulator and some websites I have found the following regex, but it only allows exactly one upper (or lower!) case character followed by a period: ^[A-Z][/.]$ Basically I only need to know how to force upper case characters, and how I can repeat the validation to allow more the one occurence of an upper case character followed by a period.

  • In MSSQL, how do I create a reference variable to a table?

    - by Jón Trausti
    Hello. I'm currently using sp_executesql to execute a T-SQL statement with a dynamic table name. However, it is really ugly to see something like: set sql = 'UPDATE '+Table_Name+' SET ... WHERE '+someVar+' = ... AND '+someVar2' = ...' sp_executesql sql What I would rather like to have is a TABLE variable of which is a reference to a table, so I could do for example: UPDATE TableRef SET ... WHERE ... Because when I have really long T-SQL statements it gets really hard to read due to the format of it within a string. Any suggestions would be helpful. Thanks!

  • Eclipse Class File Metadata

    - by Alex
    In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition). Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options: How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this. How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition? Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler. Thank you in advance.

  • How would you parse the location text from Twitter to get the latitude/longitude in Objective-C?

    - by Brennan
    The location text from Twitter could be just about anything. Sometimes Twitter clients set the location with the user's latitude and longitude in the following format. "\U00dcT: 43.05948,-87.908409" Since there is no built-in support for Regular Expressions in Objective-C I am considering using the NSString functions like rangeOfString to pull the float values out of this string. For my current purpose I know the values with start with 43 and 87 so I can key off those values this time but I would prefer to do better than that. What would you do to parse the latitude/longitude from this string?

  • Trouble using SFML with GCC and OS X

    - by user1322654
    I've been trying to get SFML working for a while now and I've been trying to get it working using GCC. I'm on OS X by the way. I followed the standard Linux instructions and using the Linux 64-bit download however when it comes to compiling... g++ -o testing main.cpp -lsfml-system This happens: main.cpp: In function ‘int main()’: main.cpp:7: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:9: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:10: error: ‘Sleep’ is not a member of ‘sf’ So I thought it could be due to not using includes, so I changed my gcc compile command to: g++ -o testing main.cpp -I ~/SFML-1.6/include/ -lsfml-system and now I'm getting this error: ld: warning: ignoring file /usr/local/lib/libsfml-system.so, file was built for unsupported file format which is not the architecture being linked (x86_64) Undefined symbols for architecture x86_64: "sf::Clock::Clock()", referenced from: _main in ccZEiB7b.o "sf::Clock::GetElapsedTime() const", referenced from: _main in ccZEiB7b.o "sf::Sleep(float)", referenced from: _main in ccZEiB7b.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status** And I have no idea what to do to fix it.

  • R.java file not updating with UI element's id

    - by Mohit Deshpande
    I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?

  • MySQL storing negative and positive decimals

    - by Shishant
    Hello, I want to be able to store -11.99 and +11.99 kind of values in mysql db I am thinking of decimals instead of varchar. But reading mysql site I found out that its incompatible with older versions of mysql As a result of the change from string to numeric format for DECIMAL storage, DECIMAL columns no longer store a leading + or - character or leading 0 digits. Before MySQL 5.0.3, if you inserted +0003.1 into a DECIMAL(5,1) column, it was stored as +0003.1. As of MySQL 5.0.3, it is stored as 3.1. For negative numbers, a literal - character is no longer stored. Applications that rely on the older behavior must be modified to account for this change. So what should be the data type, If I have to give up varchar and make it compatible with older versions too?

  • How to interpret mono profiler results?

    - by Ovidiu Pacurar
    I created a console application in C# and running it on windows/.NET is 5x faster than on linux/mono or windows/mono. The app encodes some binary files into text format(JSON). I profiled the app on linux/mono using: mono --profile=default:stat myconsoleapp.exe Here is the first part of the result: prof counts: total/unmanaged: 32274/25062 23542 72.95 % mono 459 1.42 % System.Decimal:Divide (System.Decimal,System.Decimal) 457 1.42 % System.Decimal:Round (System.Decimal,int,System.MidpointRounding) 411 1.27 % /lib/libz.so.1 262 0.81 % /lib/tls/i686/cmov/libc.so.6(memmove 253 0.78 % System.Decimal:IsZero () 247 0.77 % System.NumberFormatter:Init (string,double,int) 213 0.66 % System.NumberFormatter:AppendDigits (int,int) 72.95 % mono? Are mono internals using 3 quarters of the total execution time?

  • Using EXR images in OpenCV

    - by Nestor
    Hi there! I'm currently working on a project with OpenEXR and I would like to implement some Blob detection algorithms. To do this I figured that I could use OpenCV as it says in the documentation that it can open OpenEXR format files. I have all the libraries installed and working as I've been doing other things. I open a simple jpg file with openCV cvLoadImage. It works fine. But when i try to open any .exr file it doesn't seam to like it. I get a gray window where there should be the image display. Has anyone done any tests with OpenCV and OpenEXR libraries working together? Have they worked for you? What do you think? Thanks.

  • Client-side or server-side processing?

    - by Nick
    So, I'm new to dynamic web design (my sites have been mostly static with some PHP), and I'm trying to learn the latest technologies in web development (which seems to be AJAX), and I was wondering, if you're transferring a lot of data, is it better to construct the page on the server and "push" it to the user, or is it better to "pull" the data needed and create the HTML around it on the clientside using JavaScript? More specifically, I'm using CodeIgniter as my PHP framework, and jQuery for JavaScript, and if I wanted to display a table of data to the user (dynamically), would it be better to format the HTML using CodeIgniter (create the tables, add CSS classes to elements, etc..), or would it be better to just serve the raw data using JSON and then build it into a table with jQuery? My intuition says to do it clientside, as it would save bandwidth and the page would probably load quicker with the new JavaScript optimizations all these browsers have now, however, then the site would break for someone not using JavaScript... Thanks for the help

If you're interested, the code format I am attempting to use is as follows: CREATE USER username, password, pid.

  • Cannot find code completion and suggestions in Aptana 2.0

    - by Benjamin
    Greetings, I recently started using Aptana 1.5 to work on a site via FTP, developing pages in .php format with a mixture of HTML, CSS, jQuery, and -- naturally -- PHP. I develop a page with all of these elements together to save time, then separate them. One thing that I really liked about Aptana 1.5 was that it completed code (brackets, parentheses, etc) and suggested things as I typed. I upgraded to 2.0 today and cannot figure out for the life of me how to bring back all of these capabilities -- or remember if I had to do anything in 1.5 to get them. Here is a picture of what I am looking for Notice the suggestion for margin: and the "HTML, Js, CSS" up top. Any help with getting this to work in 2.0 would be greatly appreciated. Ever since installing 2.0, 1.5 has been throwing error messages and I can't seem to get my FTP settings to stay locked in.
