I hope this can be done

• Should I enter my Office product key before running sysprep?

  - by stickmangumby

  I'm planning on cloning a Windows XP install, and am a little confused about sysprep. I know that it blanks out the XP product key, but what about other software? If I install Office 2007 and enter a product key, then use sysprep and create an image, will I be able to enter a new product key in clones I create from the image? Or will they all have duplicate product keys?

• ssh tunnel via multiple hops

  - by Mala

  Tunneling data over ssh is pretty straight-forward: ssh -D9999 [email protected] sets up port 9999 on your localhost as a tunnel to foreignhost.com, but I have more specific need: I am working locally on localhost host1 is accessible to localhost host2 only accepts connections from host1 I need to create a tunnel from localhost to host2 Effectively I want to create a "multi-hop" ssh tunnel. How can I do this? Ideally, I'd like to do this without needing to be superuser on any of the machines.

  - by Joseph Ghassan

  Hi guys, I have deployed successfully a C# windows service on a windows 7 machine.

• Non-Git Github?

  - by Mihir Singh

  This is probably a really weird question... but is there a non-git Github? I want a place to post my projects and share my code (like Github) but I don't want to have to works with versions, commits, etc. I don't like having to create a link between my folder and my git repo and then push the changes etc. In addition, I don't want to have to have a local copy to create or add files; I can edit existing files in Github, but to create or add files, I have to do it locally and then commit and push. I'm not sure if this is the best site to ask on, but I figured someone might have the answer. Thanks in advance.

• Problems creating service using sc.exe

  - by Shoko

  I have this command to create a service: sc create svnserve binpath="\"C:\Program Files (x86)\Subversion\bin\svnserve.exe\" --service --root C:\SVNRoot" displayname="Subversion" depend=tcpip start=auto obj="NT AUTHORITY\LocalService" Unfortunately, it seems not to work, even though the syntax is correct. When I run it, I get the usage instructions (which I guess is a way of telling me that I've supplied incorrect arguments, although I have no idea what incorrect argument I might have supplied). Can anyone help me out of my difficulty? Thanks!

• Implementing sub fields in a PropertyGrid

  - by evolve

  Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.

• MS Access Mark Duplicates in order of appearance - using the function RankOfDup: (SELECT Count(*) ...)

  - by veska stoyanova

  I'm trying to create Ranking that shows the sequence of agreements for the two fields Customers and Agreements. The number for agreements must be unique, whereas customers can repeat. The formula RankOfDup: (SELECT Count(*) FROM Data a WHERE a.customer=Data.customer And a.agreement >= Data.agreement) Works beautifully but after this query with columns Agreement, Customer and RankofDup, I need to create crosstab that transposes the RankofDub. It works when I make the table first and then create query but my data is too large so I'm trying to put the select query with the ranking in a crosstab query. However, when I try to do this Access gives error message that microsoft jet ... doesn't recognise Data.customer? Any ideas how I can fix this?

• Using STI path with same controller

  - by TenJack

  I am using STI and am wondering, do I have to have a separate controller for each model? I have a situation where I only use the create and edit actions for one model in the STI relationship, but I get an 'undefined method' error if I try to do a form for. More specifically, I have two models that inherit from List: class RegularList < List class OtherList < List and I have a lists controller that handles these actions, but I only create new models with RegularList using forms. i.e. the only situation where I use a form_for to create a new List object is with RegularList. What I would like to do is something like: class ListsController < ApplicationController def new @list = RegularList.new end otherwise the route for creating a new list looks like regular_list/new but I would like it to just be list/new. Thoughts?

• Convert MBR to GPT - Without any OS

  I just got a new laptop without any OS (it had FreeDOS, but not anymore). When I go to Windows Installer and try to create a new partition from un-allocated space, I don't get any Error message but the installer is unable to create the partition. At the bottom of the installer window, there's a warning which says something like, Windows cannot install on MBR *partition. On EFI systems, Windows can only install on GPT *partition How can I convert MBR to GPT without any OS?

• Server Emulator Design Pattern

  - by adisembiring

  I wanna build server socket emulator, but I want implement some design pattern there. I will described my case study that I have simplified like these: My Server Socket will always listen client socket. While some request message come from the client socket, the server emulator will response the client through the socket. the response is response code. '00' will describe request message processed successfully, and another response code expect '00' will describe there are some error while processing the message request. IN the server there are some UI, this UI contain check response parameter such as. response code timeout interval While the server want to response the client message, the response code taken from input parameter response form UI check the timeout interval, it will create sleep thread and the interval taken from timeout interval input from UI. I have implement the function, but I create it in one class. I feel it so sucks. Can you suggest me what class / interface that I must create to refactor my code.

• Hibernate doesn't generate cascade

  - by Shervin

  Hi. I have a set hibernate.hbm2ddl.auto to create so that Hibernate creates the tables in mysql for me. However, it doesn't seem that hibernate correctly adds Cascade on the references in the table. It does however work when I for instance delete a row, and I have a delete cascade as hibernate annotation. So I guess that means that Hibernate reads the annoation on runtime, and perform cascading manually? Is that normal behavior? For instance: @Entity class Report { @OneToOne(cascade = CascadeType.ALL) public File getPdf() { return pdf; } } Here I have set cascade to ALL. However, when running show create table Report Report | CREATE TABLE `Report` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `pdf_id` bigint(20) DEFAULT NULL, PRIMARY KEY (`id`), KEY `FK91B14154FDE6543A` (`pdf_id`), CONSTRAINT `FK91B14154FDE6543A` FOREIGN KEY (`pdf_id`) REFERENCES `File` (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 | It doesn't say anything about cascading other then the foreign key. In my opinion, it should have added the ON DELETE CASCADE ON DELETE UPDATE

• Self-signed ceritificates for many users/browsers/sites

  - by Demiurg

  Here is my problem - I have a lot of users using different browsers accessing many internal web sites using https. I can create my own Certificate Authority, than create a certificate for each server and after that have all the users import it. Obviously, it cannot work in reality - there are too many users and too many sites, and some sites will be added in the future. I'm looking for a way to automate this. Is there a way to create a certificate so that all major browsers (IE, FF, Opera, Chrome and Safari) would trust it for all servers ? If so, what is the best way to install it automatically in all major browsers ?

• How do you refresh the contents of an R gWidget?

  - by Richie Cotton

  I'm creating a GUI in R using gWidgets (more specifically gWidgetstcltk). I'd like to know how to update the contents of selection-type widgets, such as gdroplist and gtable. I currently have a rather hackish method of deleting the widget and re-creating it. I'm sure there's a better way. This simple example displays all the variables in the global environment. library(gWidgets) library(gWidgetstcltk) create.widgets <- function() { grp <- ggroup(container = win) ddl <- gdroplist(ls(envir = globalenv()), container = grp) refresh <- gimage("refresh", dirname = "stock", container = grp, handler = function(h, ...) { if(exists("grp") && !is.null(grp)) { delete(win, grp) rm(grp) } grp <- create.widgets() } ) } win <- gwindow() grp <- create.widgets()

• iPhone: Add background button to view when UITableView has no cells

  - by Nic Hubbard

  I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, "No records have been added, Tap to add one", then they click and we create a new one. I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using: if ([[fetchedResultsController sections] count] == 0) { self.tableView.hidden = YES; // Create button w/ image UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(0, 0, 100, 50); [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal]; [self.view addSubview:btn]; } Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white...

• Select columns from join table only without requiring a join

  - by Kent Boogaart

  Given these tables: create table Orders ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table Items ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table OrdersItems ( OrderId INT not null, ItemId INT not null, primary key (OrderId, ItemId) ) Is it possible to use HQL/criteria API to contruct a query that results in the following SQL: SELECT [OrderId], [ItemId] FROM [OrdersItems] I've tried both of these approaches: var hqlResults = session .CreateQuery("select order.id, item.id from Order order inner join order.Items item") .List(); var criteriaResults = session .CreateCriteria<Order>() .CreateAlias("Items", "item", NHibernate.SqlCommand.JoinType.None) .SetProjection(Projections.Property("id"), Projections.Property("item.id")) .List(); But both approaches insist on generating a join (or fail because the join isn't present, in using criteria), resulting in SQL such as: select order.Id, item.Id from Orders order inner join OrdersItems ordersItems on order.Id = ordersItems.ArticleId inner join Items item on ordersItems.CategoryId = item.Id Is there any way to have NHibernate generate a query that selects columns only from the join table, without requiring a join?

• What is the best way to manage application screens in SWT?

  - by parxier

  I'm creating a standalone SWT desktop application that has around 10 different screens (few wizards, help, forms, etc). Some elements on screen don't change at all (like header, background, etc) and there is a working area that changes depending on what is clicked, etc. What is the best way to manage application screens? Do I need to create all screen at startup and then show/hide them depending on what is clicked? Or do I need to create those screens dynamically? Also, I couldn't find any way to show/hide a Composite, do I need to dispose it and then create again? What is the best practice? I'm new to SWT developing outside of Eclipse so any help would be beneficial.

• Perl DBI - run SQL Script with multiple statements

  - by guigui42

  I have a sql file test.sql used to run some SQL (create object / update / delete / insert) that can look like this CREATE TABLE test_dbi1 ( test_dbi_intr_no NUMBER(15) , test_dbi_name VARCHAR2(100); UPDATE mytable SET col1=1; CREATE TABLE test_dbi2 ( test_dbi_intr_no NUMBER(15) , test_dbi_name VARCHAR2(100); Usually, i would just use SQLPLUS (from within Perl) to execute this test.sql using this command : @test.sql Is there a way to do the same thing, using DBI in Perl ? So far, i found DBI can only execute one statement at a time, and without the ";" at the end.

• should I put my multi-device btrfs filesystem on disk partitions or raw devices?

  - by Glyph

  If I'm going to create a multi-device btrfs filesystem. The official recommendation from the documentation apppears to be to create it on raw devices; i.e. /dev/sdb, /dev/sdc, etc, but this is not explained. Are there any advantages to creating a partition table on these devices first, either GPT or MBR, and then creating the filesystem on /dev/sdb1, /dev/sdc1 et cetera? Does feeding btrfs whole devices have some particular advantage, or are these basically equivalent?

• Database Design Question

  - by deniz

  Hi, I am designing a database for a project. I have a table that has 10 columns, most of them are used whenever the table is accessed, and I need to add 3 more rows; View Count Thumbs Up (count) Thumbs Down (Count) which will be used on %90 of the queries when the table is accessed. So, my question is that whether it is better to break the table up and create new table which will have these 3 columns + Foreign ID, or just make it 13 columns and use no joins? Since these columns will be used frequently, I guess adding 3 more columns is better, but if I need to create 10 more columns which will be used %90 of the time, should I add them as well, or create a new table and use joins? I am not sure when to break the table if the columns are used very frequently. Do you have any suggestions? Thanks in advance,
