• Is there a way to make Nautilus move files under version control using the VCS's move command?

  - by Matthew

  For example, say I moved a file from /project/file.cs to /project/subdir/file.cs. It would be nice if nautilus automatically converted this to bzr mv /project/file.cs /project/subdir/file.cs. Is it possible to set this up? It would also be nice if I was warned when doing a plain old mv on version controlled files, but I suppose that's a separate question.

• Differences setting content in Forms.WebBrowser control via DocumentText vs. Url

  - by jeffamaphone

  If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My question is, what's going on under the covers here that is different? I've verified in both cases that the path to the images (via RClick-View Source) is the same and that all the images do, indeed, exist. In both cases the HTML is exactly the same. Any light that could be shed on this would be appreciated. Thanks!

• .classpath and .project - check into version control or not?

  - by amarillion

  I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

• Should old/legacy/unused code be deleted from source control repository?

  - by Checkers

  I've encountered this in multiple projects. As the code base evolves, some libraries, applications, and components get abandoned and/or deprecated. Most people prefer to keep them in. The usual argument is that the code does not really take any space, it can be left alone until needed again. So a repository slowly turns into a cesspool of legacy code, where it's hard to find anything. Some people delete old code, since it creates clutter, raises more questions for new people, and you can restore any old snapshot of the code base anyway. However you can't always find the old code if you don't know where to look, as none of the (common) VCS I know offer search over the entire repository including all historical revisions, and the only way to search the old files is to check out the revision where the deleted file exists. What would be a good approach to repository management?

• Is using distributed source control like Mercurial worthwhile for a team of one?

  - by Steve McLeod

  I currently use Subversion for my one-person software company. Is it worthwhile moving to Hg (Mercurial)? Or are the benefits only realisable with a multiperson team?

• What do you do in your source control repository when you start a rewrite of a program?

  - by Max Schmeling

  I wrote an application a while back and have been maintaining it for a while now, but it's gotten to the point where there's several major new features to be added, a ton of changes that need made, and I know quite a few things I could do better, so I'm starting a rewrite of the entire program (using bits and pieces from original). My question is, what do you do with SVN at this point? Should I put the new version somewhere else, or should I delete the files I no longer need, add the new files, and just treat it like normal development in SVN? How have you handled this in the past?

• Does a Distributed Version Control System really have no centralised repository?

  - by John

  It might seem a silly question, but how do you get a working drectory set up without a server to check out from? And how does a business keep a safe backed up copy of the repo? I assume then there must be a central repo... but then how exactly is it 'distributed'? I always thought of a server-client (SVN) Vs peer-2-peer (GIT) distinction, but I don't believe that can be correct unless tools like GIT are dependent on torrent-style technology?

• Do Distributed Version Control Systems promote poor backup habits?

  - by John

  In a DVCS, each developer has an entire repository on their workstation, to which they can commit all their changes. Then they can merge their repo with someone else's, or clone it, or whatever (as I understand it, I'm not a DVCS user). To me that flags a side-effect, of being more vulnerable to forgetting to backup. In a traditional centralised system, both you as a developer and the people in charge know that if you commit something, it's held on a central server which can have decent backup solutions in place. But using a DVCS, it seems you only have to push your work to a server when you feel like sharing it. It's all very well you have the repo locally so you can work on your feature branch for a month without bothering anyone, but it means (I think) that checking in your code to the repo is not enough, you have to remember to do regular pushes to a backed-up server. It also means, doesn't it, that a team lead can't see all those nice SVN commit emails to keep a rough idea what's going on in the code-base? Is any of this a real issue?

• Do you have to call .Save() when modifying a application setting that is bound to a control property

  - by Jordan S

  I am programming in .NET I have an application setting of type string. On my form I have a textbox. I bound the text property of the textbox to my application setting. If I type something in the textbox it changes the value that is held in the Application setting but the next time I start the program it goes back to the default value. Do I need to call Properties.Settings.Default.Save(); after the text is entered for the new value to be saved? Shouldn't it do this automatically? Is there a way I can make it do it automatically?

• Should custom data elements be stored as XML or database entries?

  - by meteorainer

  There are a ton of questions like this, but they are mostly very generalized, so I'd like to get some views on my specific usage. General: I'm building a new project on my own in Django. It's focus will be on small businesses. I'd like to make it somewhat customizble for my clients so they can add to their customer/invoice/employee/whatever items. My models would reflect boilerplate items that all ModelX might have. For example: first name last name email address ... Then my user's would be able to add fields for whatever data they might like. I'm still in design phase and am building this myself, so I've got some options. Working on... Right now the 'extra items' models have a FK to the generic model (Customer and CustomerDataPoints for example). All values in the extra data points are stored as char and will be coerced/parced into their actual format at view building. In this build the user could theoretically add whatever values they want, group them in sets and generally access them at will from the views relavent to that model. Pros: Low storage overhead, very extensible, searchable Cons: More sql joins My other option is to use some type of markup, or key-value pairing stored directly onto the boilerplate models. This coul essentially just be any low-overhead method weather XML or literal strings. The view and form generated from the stored data would be taking control of validation and reoganizing on updates. Then it would just dump the data back in as a char/blob/whatever. Something like: <datapoint type='char' value='something' required='true' /> <datapoint type='date' value='01/01/2001' required='false' /> ... Pros: No joins needed, Updates for validation and views are decoupled from data Cons: Much higher storage overhead, limited capacity to search on extra content So my question is: If you didn't live in the contraints impose by your company what method would you use? Why? What benefits or pitfalls do you see down the road for me as a small business trying to help other small businesses? Just to clarify, I am not asking about custom UI elements, those I can handle with forms and template snippets. I'm asking primarily about data storage and retreival of non standardized data relative to a boilerplate model.

• datacenter network change control best practices

  - by jpolache

  I have been tasked with compiling a list of possible network equipment changes at a data center. The task includes tagging which changes need change control and which don't. Does anyone know of a "best practices" list that I can start from? The methods for doing change control at this data center are well established. The list would be of specific configuration items that should or should not be included in the change control process, of example; static route entries switch port assignments firewall rule additions/changes etc.

• Remote screen control software (such as VNC) with permission mechanism

  - by xuhdev

  Does anyone know a kind of software that allows controlling of other computer, but the server can configure permission control? For example, the server can define five users, one of them can control, but the other four of them can only view. Also, file transfer support is required. I've tried TightVNC, it works fine with anything else, but it just does not support user permission control. RAdmin can serve this job, but I wish to find some software which is free. Thank you!

• What does CONTROL mean in the context of the Certificate

  - by Ram

  Hi Everyone, I am trying to implement encryption in sql server 2005 through Certificate and Symmetric Key and i came to know that the application user should have the following access in order to Encrypt and Decrypt Data 1) CONTROL permission on Certificate and 2) REFERENCES on the Symmetric Key (Let me know if i am wrong) Now my concern is what does CONTROL mean in the context of Certificate? If my User1 has Control permission on my certificate Cert1 What all can he do, Is there a way to restrict him further, but user1 still be able to Encrypt\Decrypt the data I could not find any good practice doc for certificate and key management so can some one advice the good practice for this Thanks, Ram

• Excel: Find a specific cell and paste the value from a control cell into it

  - by G-Edinburgh

  I have two columns one containing the room number, e.g. B-CL102, the other containing a varying integer. I want to enter a different, manually determined, integer in a third column. Whether by macro or native Excel, is there a way to use two control cells at the top of the sheet, type the room number into one and the different integer matching that room into another. I have minimal experience with macros essentially just the basics. I tried to use a V-Lookup formula to look at the two control cells (Range) and then fill in the new column, however I don't know how to then fix that value so that it doesn't change when I change the values in the control cells.

• Using SQL Source Control with Fortress or Vault &ndash; Part 2

  - by AjarnMark

  In Part 1, I started talking about using Red-Gate’s newest version of SQL Source Control and how I really like it as a viable method to source control your database development.  It looks like this is going to turn into a little series where I will explain how we have done things in the past, and how life is different with SQL Source Control.  I will also explain some of my philosophy and methodology around deployment with these tools.  But for now, let’s talk about some of the good and the bad of the tool itself. More Kudos and Features I mentioned previously how impressed I was with the responsiveness of Red-Gate’s team.  I have been having an ongoing email conversation with Gyorgy Pocsi, and as I have run into problems or requested things behave a little differently, it has not been more than a day or two before a new Build is ready for me to download and test.  Quite impressive! I’m sure much of the requests I put in were already in the plans, so I can’t really take credit for them, but throughout this conversation, Red-Gate has implemented several features that were not in the first Early Access version.  Those include: Honoring the Fortress configuration option to require Work Item (Bug) IDs on check-ins. Adding the check-in comment text as a comment to the Work Item. Adding the list of checked-in files, along with the Fortress links for automatic History and DIFF view Updating the status of a Work Item on check-in (e.g. setting the item to Complete or, in our case “Dev-Complete”) Support for the Fortress 2.0 API, and not just the Vault Pro 5.1 API.  (See later notes regarding support for Fortress 2.0). These were all features that I felt we really needed to have in-place before I could honestly consider converting my team to using SQL Source Control on a regular basis.  Now that I have those, my only excuse is not wanting to switch boats on the team mid-stream.  So when we wrap up our current release in a few weeks, we will make the jump.  In the meantime, I will continue to bang on it to make sure it is stable.  It passed one test for stability when I did a test load of one of our larger database schemas into Fortress with SQL Source Control.  That database has about 150 tables, 200 User-Defined Functions and nearly 900 Stored Procedures.  The initial load to source control went smoothly and took just a brief amount of time. Warnings Remember that this IS still in pre-release stage and while I have not had any problems after that first hiccup I wrote about last time, you still need to treat it with a healthy respect.  As I understand it, the RTM is targeted for February.  There are a couple more features that I hope make it into the final release version, but if not, they’ll probably be coming soon thereafter.  Those are: A Browse feature to let me lookup the Work Item ID instead of having to remember it or look back in my Item details.  This is just a matter of convenience. I normally have my Work Item list open anyway, so I can easily look it up, but hey, why not make it even easier. A multi-line comment area.  The current space for writing check-in comments is a single-line text box.  I would like to have a multi-line space as I sometimes write lengthy commentary.  But I recognize that it is a struggle to get most developers to put in more than the word “fixed” as their comment, so this meets the need of the majority as-is, and it’s not a show-stopper for us. Merge.  SQL Source Control currently does not have a Merge feature.  If two or more people make changes to the same database object, you will get a warning of the conflict and have to choose which one wins (and then manually edit to include the others’ changes).  I think it unlikely you will run into actual conflicts in Stored Procedures and Functions, but you might with Views or Tables.  This will be nice to have, but I’m not losing any sleep over it.  And I have multiple tools at my disposal to do merges manually, so really not a show-stopper for us. Automation has its limits.  As cool as this automation is, it has its limits and there are some changes that you will be better off scripting yourself.  For example, if you are refactoring table definitions, and want to change a column name, you can write that as a quick sp_rename command and preserve the data within that column.  But because this tool is looking just at a before and after picture, it cannot tell that you just renamed a column.  To the tool, it looks like you dropped one column and added another.  This is not a knock against Red-Gate.  All automated scripting tools have this issue, unless the are actively monitoring your every step to know exactly what you are doing.  This means that when you go to Deploy your changes, SQL Compare will script the change as a column drop and add, or will attempt to rebuild the entire table.  Unfortunately, neither of these approaches will preserve the existing data in that column the way an sp_rename will, and so you are better off scripting that change yourself.  Thankfully, SQL Compare will produce warnings about the potential loss of data before it does the actual synchronization and give you a chance to intercept the script and do it yourself. Also, please note that the current official word is that SQL Source Control supports Vault Professional 5.1 and later.  Vault Professional is the new name for what was previously known as Fortress.  (You can read about the name change on SourceGear’s site.)  The last version of Fortress was 2.x, and the API for Fortress 2.x is different from the API for Vault Pro.  At my company, we are currently running Fortress 2.0, with plans to upgrade to Vault Pro early next year.  Gyorgy was able to come up with a work-around for me to be able to use SQL Source Control with Fortress 2.0, even though it is not officially supported.  If you are using Fortress 2.0 and want to use SQL Source Control, be aware that this is not officially supported, but it is working for us, and you can probably get the work-around instructions from Red-Gate if you’re really, really nice to them. Upcoming Topics Some of the other topics I will likely cover in this series over the next few weeks are: How we used to do source control back in the old days (a few weeks ago) before SQL Source Control was available to Vault users What happens when you restore a database that is linked to source control Handling multiple development branches of source code Concurrent Development practices and handling Conflicts Deployment Tips and Best Practices A recap after using the tool for a while

• microphone volume control from javascript

  - by paleozogt

  I'd like to be able to control the system microphone volume from the browser. I know that the microphone can be recorded from using Flash or Silverlight, but these don't allow control of the microphone volume. (Flash has Microphone.gain, but as its just a software multiplier, it doesn't help when the system mic volume is muted or too loud.) I've heard that HTML5 will have some sort of microphone access, but whether it will allow volume control is unclear to me. At any rate, I don't think any browsers support it yet. Are there any plugins that would allow volume control? The old Google Gears project has some AudioApi docs, though these don't seem to have made it into the actual plugin. There's also the Google Talk plugin- it seems to do some kind of gain control, but its unclear if there's an api to the plugin. Perhaps there's a draft HTML5 implementation plugin for microphone access (like indexeddb, for example)?

• Android Compound Control internal click events

  - by Simon

  Hi, I'm writing a custom compound control that extends RelativeLayout. Inside this component, there is an ImageView. I add a OnClickListener to this ImageView to animate it when the user clicks on it. But when I am in an activity using this control and I add a OnClickListener on the control, this listener is never called. It only works when I remove the other listener I have on the ImageView. Does anybody knows how to "propagate" the event to the other listeners when I catch it inside the control? Thanks! PS: I would also like to know if there is an existing control that looks like the icons on the Android desktop. Like an icon with text underneath.

• My MS Access control displays no text for appended items following an append query

  - by Zaid

  The control in question is part of a datasheet-style subform that feeds off a multi-field combo-box. The control is bound to the first field of the combo box, an ID field which is hidden from view (column width set to zero). Consequently, the second field (Code) is displayed in the control when an item is selected from the combo box. I'm using a form button action to append values to this datasheet. It seems that because I need to INSERT ID values in, the control is unable to display the corresponding Code value. Nothing is visible, unless I go manually into the combo box and select an item from it. How can I get the control to display the Code value?

• Silverlight like login/register control in WPF

  - by user293545

  If you have created a silverlight business application you will see that in the top righthand corner on the menu is a login hyperlink. Pressing it opens up a childwindow that displays a login control, within that control is another hyperlink that says "Register" if you press it, it flips the control 180 degrees around from the login control to the register control. I really like this type of animation and want to do something similar in WPF for a project I am working on. However I am not sure how to do it, has anyone done this or knows where I can find some more information on how to achieve it? Thank you

• Control.EndInvoke resets call stack for exception

  - by Brian Rasmussen

  I don't do a lot of Windows GUI programming, so this may all be common knowledge to people more familiar with WinForms than I am. Unfortunately I have not been able to find any resources to explain the issue, I encountered today during debugging. If we call EndInvoke on an async delegate. We will get any exception thrown during execution of the method re-thrown. The call stack will reflect the original source of the exception. However, if we do something similar on a Windows.Forms.Control, the implementation of Control.EndInvoke resets the call stack. This can be observed by a simple test or by looking at the code in Reflector. The relevant code excerpt from EndInvoke is here: if (entry.exception != null) { throw entry.exception; } I understand that Begin/EndInvoke on Control and async delegates are different, but I would have expected similar behavior on Control.EndInvoke. Is there any reason Control doesn't do whatever it is async delegates do to preserve the original call stack?

• ResolveURL not resolving in a user control

  - by WebJunk

  I'm trying to use ResolveUrl() to set some paths in the code behind of a custom ASP.NET user control. The user control contains a navigation menu. I'm loading it on a page that's loading a master page. When I call ResolveUrl("~") in my user control it returns "~" instead of the root of the site. When I call it in a page I get the root path as expected. I've stepped through with the debugger and confirmed, ResolveUrl("~") returns "~" in my user control code behind. Is there some other way I should be calling the function in my user control code behind to get the root path of the site?
