• Revision Control System Recommendations

  - by Jordan Arsenault

  I've reached a point in my independent development work where I would like to start using Subversion techniques. Up to now, I've been simply making backups by exporting my current database, and zipping them together with my PHP project files. I've read some articles online and watched a video with Linus Torvalds - the general verdict seems to be that Git is in and old CVS techniques are out. I'm not currently operating under Linux, I do all PHP work out of Windows - Eclipse. Due to the fact that Eclipse runs on JVM, jumping into Linux - Eclipse will be more or less transparent - file system aside. What I would like to accomplish is being able to keep a constant revision history - But I want this to be almost entirely transparent. Also, I work in an MVC framework, and I would like to be able to release my views to Designers, and have them work from within the revision control system too. Will Egit accomplish what I need? Or is it too much overhead for a one-man workforce? What do you recommend I use so that I can keep a revision history? I also require the service to be free! Thank you all - StackOverflow ftw!

• Dynamic control click event not firing properly

  - by Wil

  I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code. LinkButton lnkNext = new LinkButton(); lnkNext.Text = "Next"; lnkNext.Click += new EventHandler(NextPage); if (currentPage != objPagedDataSource.PageCount) { pnlMain.Controls.Add(lnkNext); } So in my initial page_load, the next link comes up fine. There are 5 pages in my objPagedDataSource. currentPage variable is 1. The "NextPage" event handler looks like this public void NextPage(object sender, EventArgs e) { if (HttpContext.Current.Request.Cookies["PageNum"] == null) { HttpCookie cookie = new HttpCookie("PageNum"); cookie.Value = "1"; } else { HttpCookie cookie = HttpContext.Current.Request.Cookies["PageNum"]; cookie.Value = (Convert.ToInt32(cookie.Value) + 1).ToString(); } this.BindRepeater(); } So I am incrementing the cookie I am using to track the page number and then rebinding the repeater. Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly. Not sure why, any ideas?

• Getting a stream back from a .Net remoting service that is accessible with IP v4 and v6

  - by jon.ediger

  My company has an existing .Net Remoting service that listens on a port, fronting interfaces used by external systems. This all works great with IP v4 based communications. However, this service now needs to support both IP v4 communications and IP v6 communications. I have found info that the system.runtime.remoting section of the app.config should include two channels as follows: <channel ref="tcp" name="tcp6" port="9000" bindTo="[::]" /> <channel ref="tcp" name="tcp4" port="9000" bindTo="0.0.0.0" /> The above config file changes to the System.Runtime.Remoting config section will get the remoting service responding to non-stream functions on both ip v4 and ip v6. The issue comes only when attempting to get a stream back, used to upload or download large files. In this case, instead of getting a usable stream back, the following ArgumentException is thrown instead: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses that cannot be used as a target address. Parameter name: hostNameOrAddress Is there a way to modify the app.config (in the system.runtime.remoting section, or another section) so that the service will return a stream mapped to a real ip so the client can actually upload/download files while maintaining the ability to use both IP v4 and IP v6?

• Copy new records from datatable and identify changes in old records

  - by Betite

  Assume there are two tables: Remote_table and My_table. Remote_table has 6 columns: **PROJECT JOB_TYPE MONTH YEAR** HOURS IS_DELETED 134393 70 1 2013 30 0 134393 70 2 2013 50 0 134393 70 3 2013 80 0 134393 70 10 2012 10 0 134393 70 11 2012 0 0 134393 70 12 2012 15 0 My_table is a copy of remote_table. I tried to copy only the new records from the remote_table by this query: SELECT * FROM [remote_DB].[LudanProjectManager].[dbo].Remote_table EXCEPT SELECT * FROM My_table It works OK but I get a duplicate primary key exception when changes have been made on the remote_table on the hours column. Can anyone think of a way to copy only the new records from remote_table and if changes has been made on old records, to identify them and update the my_table to correspond?

• What could the negative effects be of attaching to a process as a debugger?

  - by I_like_traffic_lights

  Background A client of mine has a major problem. They have a CRM system, which was created by a single person over a period of 9 years. Unfortunatelly, a few weeks ago, this person died. I believe the company has learned their lesson, and they have started a project of rewriting the CRM system to a modern platform. I have been hired to create a solution in the meantime to make adaptations to the CRM system. I have given up understanding the code, as this would take too long. My solution, is therefore, to make a window and show this on top of the CRM system, whenever this CRM system is showing. This part works fine, but my major problem is extracting the data from the CRM system. Proposed solution After excluding 6 approaches, including runtime code injection, memory searching, database integration, I have arrived at attaching to the process as a debugger, so I get notified about event, and use this in combination with reading from process memory. This approach seems to work, but I am worried about possible side-effects of this approach. Question What are the dangers of using this in a production environment, where there are 250 employees utilizing the system. Needless to say, I cannot risk reducing the already shaky stability of the system.

• How to get rid of bogus changes in git?

  - by zaza

  I'm a happy user of PortableGit 1.7.0.2. Today I wanted to pull a project changes from GitHub.com repository, so I did git pull. It failed with the following message: error: Your local changes to 'main.rb' would be overwritten by merge. Aborting.. I didn't care about the local changes so I typed git reset --hard HEAD (git clean from here didn't help neither), but it didn't work. When asked for git status I was still able to see the file as modified. git diff showed me that each line of the file has been modified, while git diff -b showed no differences at all, so I guess this is a line ending issue. Which is strange because the code is only pushed from Windows machines. Anyway, the question is: how can I ignore the local, bogus changes and merge with the latest changes from the remote repository?

• Set registry to control working dir when associating file-type with application

  - by John

  I'm using Inno for an installer, and I want to associate a file type with my app: Root: HKCR; Subkey: ".rpl"; ValueType: string; ValueName: ""; ValueData: "MyReplay"; Flags: uninsdeletevalue; Root: HKCR; Subkey: "MyReplay"; ValueType: string; ValueName: ""; ValueData: "Replay File"; Flags: uninsdeletekey; Root: HKCR; Subkey: "MyReplay\DefaultIcon"; ValueType: string; ValueName: ""; ValueData: "{app}\bin\MyApp.ico,0"; Flags: uninsdeletekey; Root: HKCR; Subkey: "MyReplay\shell\open\command"; ValueType: string; ValueName: ""; ValueData: """{app}\bin\MyApp.exe"" ""%1"""; Flags: uninsdeletekey; Right now, double-clicking a .rpl file launches the app, but the working dir appears to be where the .rpl file is located, so the app crashes as it can't load any data. Is it posible to set the registry to control the start/working dir for file associations as well as the app that is launched? Or does my app itself need to be able to work around this?

• Git svn - no changes, no branches (except master), rebase/info is not working

  - by ex3v

  I know that similar questions were asked before, but I think my is a little bit different, so please don't point me to existing threads. I'm migrating our old svn repo to git. I did git svn clone path --authors-file abc.txt and everything seemend legit to me. Then I did git remote add origin xyz and git push --all origin and it also worked. I created this repo as test one, with only me having access to both local repo and origin. No changes were made in project held on this repo, nothing to commit, no pushing and so on. There is also only one branch, because someone initialized svn years ago without creating proper folder structure (branches, trunk, tags). Meanwhile someone pushed their work to svn, so I tried to git svn fetch (which worked), and git svn rebase which didn't, giving me error: Unable to determine upstream SVN information from working tree history Is there any reason why git svn decided to stop working?

• Deploy PHP website to client server without showing PHP files

  - by ColmF

  I asked a recent question regarding the use of readfile() for remotely executing PHP, but maybe I'd be better off setting out the problem to see if I'm thinking the wrong way about things, so here goes: I have a PHP website that requires users to login, includes lots of forms, database connections and makes use of $_SESSION variables to keep track of various things I have a potential client who would like to use the functionality of my website, but on their own server, controlled by them. They would probably want to restyle the website using content and CSS files local to their server, but that's a problem for later I don't want to show them my PHP code, since that's the value of what I'd be providing. I had thought to do this with calls to include() from the client's server to mine, which at least keeps variable scope intact, but many sites (and the PHP docs) seem to recommend readfile(), file_get_contents() or similar. Ideally I'd like to have a simple wrapper file on the client's server for each "real" one on my server. Any suggestions as to how I might accomplish what I need? Thanks, ColmF

• Designers, Expression or SharePoint Designer, and real source control

  - by David Lively

  I'm trying desperately to move from VSS to a real source control system. Options include TFS and SVN. My designers need to keep their ability to modify source files and instantly preview their changes in a browser without having to commit their changes. Using FPSE with VSS, this works flawlessly, since saving a file causes the copy in the working folder on the dev server to be updated, so they can just save and refresh their browser which is pointed at the dev server. The site in question consists of 350k+ lines of classic ASP code and some new ASP.NET MVC. They only need to be able to modify views within the MVC code, not C#. Though Expression includes a version of Cassini for local debugging, Cassini does not support classic ASP. Surely someone has solved this problem before. It can't be necessary to install IIS on each designer's machine (this is absolutely untenable). I need a way to have a common working folder on a dev webserver updated whenever someone saves a file locally, just like using FPSE. I'd rather not write an FPSE proxy that knows how to talk to TFS/SVN. Any suggestions? (I know I've asked this question in the past, but I haven't yet found a solution.)

• Sending a Java object from my Android phone to my Computer

  - by TehGoose

  Hi, I was wondering what the simplest program for sending an object from my Andriod phone to my computer wirelessly (via LAN) would be. I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start. What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me. Could anyone help me out?

• How do I use link_to_remote to pass then render a partial in rails?

  - by Angela

  I want to create several link_to_remote links that are campaign names: <% @campaigns.each do |campaign| %> <!--link_to_remote(name, options = {}, html_options = nil)--> <%= link_to_remote(campaign, :update => "campaign_todo", :url => %> <% end %> I want the output to update on the page to render a partial, which runs a loop through the values associated with the campaign. The API docs says this will render a partial, but I'm not clear where the name of the :partial template is passed in, either here or in the controller Thanks.

• Expanding a row in a div-based table

  - by magneticMonster

  I have a stack of <div> elements that show a name. I'd like to include a + link off to the side that, when clicked, expands the <div> and adds more detailed information (from a RoR controller). After poking around on the net, I found link_to_remote and related RoR stuff, but I can't seem to get the right combination to work together. Can someone point me to a tutorial or show what the controller and view interaction should look like? Thanks!

• JQuery Control Update Not Happening

  - by Mad Halfling

  Hi, I've got a script that disables a button input control, empties a table body and then (after an AJAX call) re-populates it. It all works fine but sometimes there are a lot of rows in the table so the browser (IE) takes a while to empty and refill it. The strange thing is, while the rows are being emptied, the button still appears to be enabled, however if I put an alert between the button being disabled and the tbody being emptied, the button works properly, disabling visibly before the the alert comes up. Is there any way I can get the button to update before the resource consuming table emptying process/command commences? Thx MH Code sample, as requested (but it's not complex, so I didn't initially include it) $('#Search').attr('disabled', true); $('#StatusSpan').empty(); $('#DisplayTBody').empty(); then I perform my AJAX call, re-enable the button and repopulate the table. As I mentioned, normally this is really quick and isn't a problem, but if there are, say, 1500 rows in the table it takes a while to clear down but the 'Search' button doesn't update on the screen, however if I put an alert after the .attr('disabled' line the button visibly updates when the alert box is up, but without that the button doesn't visibly disable until after the table clears (which is about 3 or 4 seconds with 1500 rows), it just stays in it's down/"mid-press" state. I don't have a problem with the time the browser is taking to render the table changes, that's just life, but I need the users to see visible feedback so they know the search has started

• Binding a single array cell to a WPF control

  - by yomi

  Hi, I have a bool array of size 4 and I want to bind each cell to a different control. This bool array represents 4 statuses (false = failure, true = success). This bool array is a propery with a class: class foo : INotifyPropertyChanged { ... private bool[] _Statuses; public bool[] Statuses { get {return Statuses;} set { Statuses = value; OnPropertyChanged("Statuses"); } } In XAML there are 4 controls, each one bound to one cell of the array: ... Text="{Binding Path=Statuses[0]}" ... ... Text="{Binding Path=Statuses[1]}" ... ... Text="{Binding Path=Statuses[2]}" ... ... Text="{Binding Path=Statuses[3]}" ... The problem is that the notify event is raised only when I change the array itself and isn't raised when I change one value within the array, i.e, next code line raises the event: Statuses = new bool[4]; but next line does not raises the event: Statuses [0] = true; How can I raise the event each time one cell is changed?

• Window manipulation and inctences control

  - by touki

  In my application there are only 2 windows — win_a & win_b, on each of these windows there is button that call another window, e.g. click on btn1 of win_a will call win_b, click on btn2 of win_b will show win_a. Desired behaviour: 1. Only one instance of object is premitted at the same time, e.g. situation, where 2 instances of win_a running at the same time is not permitted. When you click on button that calls windows that already exist this action will only change a focus to needed window. If you call a window that previously had been created, but after this has been closed this action will create a new instance of this window. E.g. there are 2 running windows. you close one of them and after try to call this window back, so related button will create it. How to write it in WPF (XAML + C#). For the moment I wrote a version that can create a lot of instances of the same window (no number of instances control implemented), but I want to see only one instance of the same window, as we can see it in a lot of applications. Example of my code: Window win = new Window(); win.Show(); Thanks.

• Alternative to CURL due to long waiting

  - by aalan

  Hey Guys I currently run a PHP-script using CURL to send data to another server, to do run a PHP-script that could take up to a minute to run. This server doesn't give any data back. But the CURL-request still has to wait for it to complete, and then it loads the rest of the orignal page. I would like my PHP-script to just send the data to the other server and then not wait for an answer. So my question is how should I solve this? I have read that CURL always has to wait. What are your suggestions? Thank You!

• Calculating toolbar icon width

  - by TheWzrdOz

  I am building an RDP client and I have toolbar that shows the running applications, same as the Windows toolbar. I need to support dual monitors, so my questions are 1) How do I detect that there is more than one monitor and 2) Is there a formula for calculating the width of the icons on the toolbar? I know that at the start, the width is not dependent on the number of monitors, and is always the same size. What does change is the number of icons I can display before I must start "shrinking" their width, and it will depend on the screen resolution as well. Any ideas?

• Remove a ReactiveCocoa signal from a control
