  • 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; } }

  • How to manage multiple versions of the same record

    - by Darvis Lombardo
    I am doing short-term contract work for a company that is trying to implement a check-in/check-out type of workflow for their database records. Here's how it should work... 1) A user creates a new entity within the application. There are about 20 related tables that will be populated in addition to the main entity table. 2) Once the entity is created the user will mark it as the master. 3) Another user can make changes to the master only by "checking out" the entity. Multiple users can checkout the entity at the same time. 4) Once the user has made all the necessary changes to the entity, they put it in a "needs approval" status. 5) After an authorized user reviews the entity, they can promote it to master which will put the original record in a tombstoned status. The way they are currently accomplishing the "check out" is by duplicating the entity records in all the tables. The primary keys include EntityID + EntityDate, so they duplicate the entity records in all related tables with the same EntityID and an updated EntityDate and give it a status of "checked out". When the record is put into the next state (needs approval), the duplication occurs again. Eventually it will be promoted to master at which time the final record is marked as master and the original master is marked as dead. This design seems hideous to me, but I understand why they've done it. When someone looks up an entity from within the application, they need to see all current versions of that entity. This was a very straightforward way for making that happen. But the fact that they are representing the same entity multiple times within the same table(s) doesn't sit well with me, nor does the fact that they are duplicating EVERY piece of data rather than only storing deltas. I would be interested in hearing your reaction to the design, whether positive or negative. I would also be grateful for any resoures you can point me to that might be useful for seeing how someone else has implemented such a mechanism. Thanks! Darvis

  • Parsing getopts in bash

    - by ABach
    I've got a bash function that I'm trying to use getopts with and am having some trouble. The function is designed to be called by itself (getch), with an optional -s flag (getch -s), or with an optional string argument afterward (so getch master and getch -s master are both valid). The snippet below is where my problem lies - it isn't the entire function, but it's what I'm focusing on: getch() { if [ "$#" -gt 2 ] || [ "$1" = "-h" ] || [ "$1" = "--help" ]; then echo "Usage: $0 [-s] [branch-name]" >&2 return 1 fi while getopts "s" opt; do echo $opt # This line is here to test how many times we go through the loop case $opt in s) squash=true shift ;; *) ;; esac done } The getch -s master case is where the strangeness happens. The above should spit out s once, but instead, I get this: [user@host:git-repositories/temp]$ getch -s master s s [user@host:git-repositories/temp]$ Why is it parsing the -s opt twice?

  • git filter-branch chmod

    - by Evan Purkhiser
    I accidental had my umask set incorrectly for the past few months and somehow didn't notice. One of my git repositories has many files marked as executable that should be just 644. This repo has one main master branch, and about 4 private feature branches (that I keep rebased on top of the master). I've corrected the files in my master branch by running find -type f -exec chmod 644 {} \; and committing the changes. I then rebased my feature branches onto master. The problem is there are newly created files in the feature branches that are only in that branch, so they weren't corrected by my massive chmod commit. I didn't want to create a new commit for each feature branch that does the same thing as the commit I made on master. So I decided it would be best to go back through to each commit where a file was made and set the permissions. This is what I tried: git filter-branch -f --tree-filter 'chmod 644 `git show --diff-filter=ACR --pretty="format:" --name-only $GIT_COMMIT`; git add .' master.. It looked like this worked, but upon further inspection I noticed that the every commit after a commit containing a new file with the proper permissions of 644 would actually revert the change with something like: diff --git a b old mode 100644 new mode 100755 I can't for the life of me figure out why this is happening. I think I must be mis-understanding how git filter-branch works. My Solution I've managed to fix my problem using this command: git filter-branch -f --tree-filter 'FILES="$FILES "`git show --diff-filter=ACMR --pretty="format:" --name-only $GIT_COMMIT`; chmod 644 $FILES; true' development.. I keep adding onto the FILES variable to ensure that in each commit any file created at some point has the proper mode. However, I'm still not sure I really understand why git tracks the file mode for each commit. I had though that since I had fixed the mode of the file when it was first created that it would stay that mode unless one of my other commits explicit changed it to something else. That did not appear to the be the case. The reason I thought that this would work is from my understanding of rebase. If I go back to HEAD~5 and change a line of code, that change is propagated through, it doesn't just get changed back in HEAD~4.

  • Best way to do partial update content on ASP.NET

    - by kevin
    Initially i was planning to use master page for every page in my application. At the end, i found out every times the page is changed, it reload full page even it have the same master page. I have confused the frameset with the master page. Then, i have 2 ideas in my minds to achieve it by not using master page. Using iframe and set the attribute to runat server, so that i can change the page in my codebehind.(I preferred to control the page flow in server side) Make every single child page to user control. Then dynamically load it to the panel in codebehind. Please give me some advise which method is the best in ASP.NET with AJAX enabled, or other ways that is better. Thanks.

  • sql insert query needed

    - by masfenix
    Hey guys, so I have two tables. They are pictured below. I have a master table "all_reports". And a user table "user list". The master table may have users that do not exist in the user list. I need to add them to the user list. The master table may have duplicates in them (check picture). The master list does not contain all the information that the user list requires (no manager, no HR status, no department.. again check picture).

  • How do people manage changes to common library files stored across mutiple (Mercurial) repositories?

    - by mckoss
    This is perhaps not a question unique to Mercurial, but that's the SCM that I've been using most lately. I work on multiple projects and tend to copy source code for libraries or utilities from a previous project to get a leg up on starting a new project. The problem comes in when I want to merge all the changes I made in my latest project, back into a "master" copy of those shared library files. Since the files stored in disjoint repositories will have distinct version histories, Mercurial won't be able to perform an intelligent merge if I just copy the files back to the master repo (or even between two independent projects). I'm looking for an easy way to preserve the change history so I can merge library files back to the master with a minimum of external record keeping (which is one of the reasons I'm using SVN less as merges require remembering when copies were made across branches). Perhaps I need to do a bit more up-front organization of my repository to prepare for a future merge back to a common master.

  • Content controls have to be top-level controls

    - by horatio
    I have a website that can be accessed from www.blahblah.com and special.blahblah.com. The www site always works but occasionly I get a 'Content controls have to be top-level controls in a content page or a nested master page that references a master page' error on the special site. It's exactly the same code running in both situations and the offending page doesn't even have a master page. Why would it work all the time on one and fail sometimes on the other?

  • How to break connection between a clone repository and its parent

    - by nc97217
    I have some (local) repositories, an original and some clones. The original repository has been corrupted so I'd like to get rid of it and use one of the clones as the master for future development. Is there a better way to break the connection between the new master and the original repository than simply deleting the default entry in the [paths] section of that clone's hgrc? Similarly, in the other clones, can I simply change the default entry in their hgrc files' [paths] section to point to the new master repository?

  • Beginner question about merging in git

    - by wxyz
    I'm 15 and have just started using source control systems to manage my code a little better, so I'm a little new to this stuff. Right now I have this repository: [a]---[b]---[d]---[f] master \ \ [c]---[e] develop I want to wind up here: [a]---[b]---[d]---[f]---[g] master \ / \ / [c]---[e]---/ develop where g is equivalent to performing commits [c] and [e] on [f]. This is git checkout master; git merge develop, right?

  • Finding a sequence in a List

    - by user113164
    I have a list of integers that I would like to search for a sequence. For example, if i have a master list: 1, 2, 3, 4, 9, 2, 39, 482, 19283, 19, 23, 1, 29 And I want to find sequence: 1, 2, 3, 4 I would like some easy way to fill a subset list with: 1, 2, 3, 4 + the next five integers in the master list And then remove the integers in the subset list from the master list so at the end of the operation, my lists would look like this: Master list: 19, 23, 1, 29 Subset list: 1, 2, 3, 4, 9, 2, 39, 482, 19283 Hope that makes sense. I'm guessing maybe linq would be good for something like this, but I've never used it before. Can anyone help?

  • Git doesn't sync files until committed, even if checked out in a different branch

    - by DertWaiter
    Okay, I have git 1.7.11.1 on Windows and I have a local test repository with 2 branches. One is master with index.php and help.php. I then create another branch called slave :) I run from git bash rm help.php and it disappears from the folder, but I don't stage anything. I switch to checkout master branch and it is supposed to restore file help.php because it is not modified in the master branch, isn't it? And it does not do it. When I go back to the slave branch and commit and then switch to checkout master then help.php appears. Is that the way it is supposed to to work? Why?

  • Why does placing this html within form tags change the layout?

    - by user352687
    I'm using this free Web Template - EliteCircle and have just incorporated it into a master page. The master page wraps the html in: <form id="form1" runat="server"> //master page html </form> The template almost comes out fine except the entire page is surrounded by a think white border (default CSS behavior for form?) and the footer background is half white on the very bottom. I wouldn't expect the form with id=form1 to change anything in the layout. There is nothing in the [CSS][2] with that id. When I remove the form tags from the master page (just to check) the layout is perfect, no problems. Any ideas? (Using Visual Web Developer 2008 Express) Thanks, Greg The CSS: http://www.styleshout.com/templates/preview/EliteCircle12/images/EliteCircle.css

  • SQL Server database synchronization issues

    - by George2
    Hello everyone, I have two SQL Server 2008 Enterprise databases (on two machines), and one of the databases is master database and another database is slave database (master database is read/write, slave database is readonly). I want to have daily update from master database to slave database (i.e. new data inserted/updated/deleted in master database could be synchronized to slave database daily or manually controlled). I only need to sync several tables of the databases, not all of the database. Any solutions or documents? thanks in advance, George

  • Data structure for an ordered set with many defined subsets; retrieve subsets in same order

    - by Aaron
    I'm looking for an efficient way of storing an ordered list/set of items where: The order of items in the master set changes rapidly (subsets maintain the master set's order) Many subsets can be defined and retrieved The number of members in the master set grow rapidly Members are added to and removed from subsets frequently Must allow for somewhat efficient merging of any number of subsets Performance would ideally be biased toward retrieval of the first N items of any subset (or merged subset), and storage would be in-memory (and maybe eventually persistent on disk)

  • Registering a piece of script across all the SharePoint Pages

    - by NLV
    Hello all I've a business requirement in which i need to create a SharePoint feature which registers a JavaScript across all the SharePoint pages. The only way i figured out to achieve it is that adding the script in (all) the SharePoint Master Pages or any other custom master pages present in the Site/Site Collection/Web Application while activating the feature. But i found that editing the master pages to add a Javascript snippet is not feasible. Finally i found that i could register my custom controls in the "Delegate Controls" and the custom user control i created can in turn register my script in the page. But my question is how can i handle it if the master page does not have a delegate control? Or is there any other possible solution to register a script across all the SharePoint pages?

  • Switching MySql Replication Format

    - by NNN
    I'm currently using statement-based replication. After upgrading to MySql 5.1, I'm considering using row-based replication. After reading the docs it seems that you can change the format of the master on the fly. Will the slave automatically adapt to whatever type of binary log it is sent? Do I have to make any changes to the slave or master to get ready for switching or can I simply modify the binlog_format variable on the master?

  • inheriting scope from a has_many relationship

    - by hb922
    I am using ruby on rails 3.1 and have 2 models, an event and a group. Each event has_many groups, but has to have at least one "master" group, where the column :is_master = true Class Group < ActiveRecord::Base has_many :users belongs_to :event scope :master, where (:is_master => true) end Class Event< ActiveRecord::Base has_many :groups def master_group groups.master end end I want to be able to default all properties of the master group to the event, so for example, event.users.count should be the same as event.master_group.users.count. Is there any way to do something like this? Can I do a has_many :through = master_group? Am I approaching this the wrong way? Thanks!

  • How to prevent an automerge using git?

    - by marckassay
    I am trying to merge a local branch into the master branch without having Git to do an automerge. I would like to “hand pick” what I would like to be merged into master. When I use Git’s difftool command, I am able to diff and select what I want to be added into the master branch. But then when I do a merge, I will lose what I selected prior because Git will do an automerge. I can commit the changes into master prior to the merge, but doing so seems unnatural. And Git’s mergetool is only available when there are conflicts from a merge. But if Git does an automerge then usually there aren’t conflicts, so I am unable to run the mergetool command.

  • Sync video play over network

    - by Nemesis
    Hi, I have made a media player that plays basically anything that's scheduled to it via a text file. The player can also play the exact same clip on multiple machines(PC's). The problem is the syncing. The same video starts playing on each of the machines, but they are out by about 400ms, which looks crap and if there's sound it's even worse. What I do at the moment is: One machine is set up as the master and all other machines are set up as slaves. The master decides what item will be played. It waits for a message from each of the slaves, once all slaves are connected (or after the timeout), it broadcasts the item id of the file that needs to be played. All machines then start playing that file. What I also tried: I thought that the file loading time might be the major driving factor in the sync mismatch, so I chankged the code to do the following. The master still decides what file to play. It waits for the connect message from each slave (or timeout) and transmits the item id of the file to play. All machines start playing that file but pauses it immediately. The master then again waits for a ready message from each of the slaves. As soon as all slaves responded the master sends a play message to all slaves. All machines then continue the file. This unfortunately did not improve the problem. I am now pretty sure the sync mismatch is due to network delay. How can I compensate for this? Or maybe determine the delay to each slave? All network comms are done with winsock. Any thoughts or ideas is much appreciated.
