  • Bluetooth development on Windows mobile 6 C#

    - by cheesebunz
    Hi everyone, i recently started on a project which is a puzzle slider game. This application will be using the Bluetooth, and i'm working on the mobile,Samsung omnia i900. This is how my application will work. Any user with this Samsung device plays the game and starts sliding the tiles. There is an option to search and connect to other users with the same device and application, so that they can solve the puzzle together. Right now, i'm working on the Bluetooth Part but am still new to the API. I'm using the 32feet.NET inthehandpersonal.net class library while encountering much difficulties. I am able to search for devices by using: private void btnSearch_Click(object sender, EventArgs e) { BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable; BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio; lblSearch.Text = "" + myRadio.LocalAddress.ToString(); bluetoothClient = new BluetoothClient(); Cursor.Current = Cursors.WaitCursor; BluetoothDeviceInfo[] bluetoothDeviceInfo = { }; bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10); comboBox1.DataSource = bluetoothDeviceInfo; comboBox1.DisplayMember = "DeviceName"; comboBox1.ValueMember = "DeviceAddress"; comboBox1.Focus(); Cursor.Current = Cursors.Default; } Well, to be honest this is a rip off from some sources i found on the internet but i do understand this part. Next i went on to trying to sending a simple "testing.txt" file and i'm stucked at it. I think i will be using something like the OBEX and Obexwebrequest, obexwebresponse, Uri etc. Could anyone explain it in simple terms for me so that i could understand what they are so that i could continue pairing and etc on Bluetooth development. Sorry making it this long, really appreciate if anyone did waste some time reading it :). Hope alanM sees this :) i'm using their bluetooth library.

  • Using the public ssh key from local machine to access two remote users [closed]

    - by Nick
    I have an new Ubuntu (Hardy 8.04) server; it has two users, Alice and Bob. Alice is listed in sudoers. I appended my public ssh key (my local machine's public key local/Users/nick/.ssh/id_rsa.pub) to authorized_keys in remote_server/home/Alice/.ssh/authorized_keys, changed the permissions on Alice/.ssh/ to 700 and Alice/.ssh/authorized_keys to 600, and both the file and folder are owned my Alice. Then added I Alice to sshd_config (AllowUsers Alice). This works and I can login into Alice: ssh -v [email protected] ... debug1: Offering public key: /Users/nick/.ssh/id_rsa debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Entering interactive session. Last login: Mon Mar 15 09:51:01 2010 from 123.456.789.00 I then copied the authorized_keys file remote_server/home/Alice/.ssh/authorized_keys to remote_server/home/Bob/.shh/authorized_keys and changed the permissions and ownership and added Bob to AllowUsers in sshd_config (AllowUsers Alice Bob). Now when I try to login to Bob it will not authenticate the same public key. ssh -v [email protected] ... debug1: Offering public key: /Users/nick/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /Users/nick/.ssh/identity debug1: Trying private key: /Users/nick/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). Am I missing something fundamental about the way ssh works?

  • ASPXAUTH cookie is not being saved.

    - by kripto_ash
    Hi, Im working on a web project in ASP .NET MVC 2. In this project we store some info inside an ecripted cookie (the ASPXAUTH cookie) to avoid the need to query the db for every request. The thing is the code for this part has suddenly stopped working. I reviewed the changes made to the code on the source control server for anything that could be causing it, I found nothing. I even reverted to a known working copy (working on some other persons PC, same code, etc) but after debugging, it seems the .ASPXAUTH cookie is not getting saved anymore. Instead the ASP.NET_SessionId cookie is being set... (wich before wasn't) I changed the web.config file to turn off the sessionState. This eliminated the ASP.NET_SessionId cookie from being set, but it is still not saving the auth cookie. Ive recently installed some Microsoft Windows XP Updates, but the other person (whos PC runs the application just fine) also did. After googling, some info i found pointed out to a problem with the expiration date of the cookie. Ether cus the pc didnt have the right time/date (this was not the case) and others cus of the cookie expiration date being wrongly set. (I checked and it is being set correctly)... The problem persists with other browsers besides the one im using (Chrome) i tried it with IE6. Any ideas on why this is happening? Ill continue to post any helpful information i can find. Thanks in advance.

  • ASP.NET MVC Session Expiration

    - by Andrew Flanagan
    We have an internal ASP.NET MVC application that requires a logon. Log on works great and does what's expected. We have a session expiration of 15 minutes. After sitting on a single page for that period of time, the user has lost the session. If they attempt to refresh the current page or browse to another, they will get a log on page. We keep their request stored so once they've logged in they can continue on to the page that they've requested. This works great. However, my issue is that on some pages there are AJAX calls. For example, they may fill out part of a form, wander off and let their session expire. When they come back, the screen is still displayed. If they simply fill in a box (which will make an AJAX call) the AJAX call will return the Logon page (inside of whatever div the AJAX should have simply returned the actual results). This looks horrible. I think that the solution is to make the page itself expire (so that when a session is terminated, they automatically are returned to the logon screen without any action by them). However, I'm wondering if there are opinions/ideas on how best to implement this specifically in regards to best practices in ASP.NET MVC.

  • Odd Infragistics UltraComboEditor data binding non-bug

    - by Richard Dunlap
    Within an Infragistics 8.2 UltraComboEditor, we had the following properties set via C#: DataSource = dataSource; ValueMember = "Measure"; DisplayMember = "Name"; DataBindings.Add("Value", repository, "Measure"); DataBindings["Value"].DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; where dataSource was an array of objects, each with a property Measure, and repository was an object with a property Measure. (Those strings are actually constructor parameters -- just using explicit strings to simplify the example.) In the course of some refactoring, the name of the property on the objects in the array was changed to BaseEnum (the objects are actually wrapped enumerations, for the curious), but the name of ValueMember above was not changed. And yet, the combo box binding continued to work through initial testing, beta testing, and even after release... until two customers emailed in noting that the combo box was no longer changing the underlying parameter. We were able to dig out the problem by careful study of the source code repository... despite being in the awkward position of not being able to replicate the buggy behavior internally. Two part question: What's happening under the hood that allowed the binding to continue to function, and/or what might be unique about those two users that caused the binding to (correctly) fail? (O/S version isn't alone the answer, and we get the unexpectedly functioning binding on machines that have never had a version of the software before, so we're not looking at rogue binaries). Are there tools that might have been able to warn us about the misbind, even if something was cleaning up behind?

  • how to use a regex to search backwards effectively?

    - by Asaf
    hi, i'm searching forward in an array of strings with a regex, like this: for (int j = line; j < lines.length; j++) { if (lines[j] == null || lines[j].isEmpty()) { continue; } matcher = pattern.matcher(lines[j]); if (matcher.find(offset)) { offset = matcher.end(); line = j; System.out.println("found \""+matcher.group()+"\" at line "+line+" ["+matcher.start()+","+offset+"]"); return true; } offset = 0; } return false; note that in my implementation above i save the line and offset for continuous searches. anyway, now i want to search backwards from that [line,offset]. my question: is there a way to search backwards with a regex efficiently? if not, what could be an alternative? 10x, asaf :-) clarification: by backwards i mean finding the previous match. for example, say that i'm searching for "dana" in "dana nama? dana kama! lama dana kama?" and got to the 2nd match. if i do matcher.find() again, i'll search forward and get the 3rd match. but i want to seach backwards and get to the 1st match. the code above should then output something like: found "dana" at line 0 [0,3] // fwd found "dana" at line 0 [11,14] // fwd found "dana" at line 0 [0,3] // bwd

  • LINQ-to-SQL: ExecuteQuery(Type, String) populates one field, but not the other

    - by Daniel Schaffer
    I've written an app that I use as an agent to query data from a database and automatically load it into my distributed web cache. I do this by specifying an sql query and a type in a configuration. The code that actually does the querying looks like this: List<Object> result = null; try { result = dc.ExecuteQuery(elementType, entry.Command).OfType<Object>().ToList(); } catch (Exception ex) { HandleException(ex, WebCacheAgentLogEvent.DatabaseExecutionError); continue; } elementType is a System.Type created from the type specified in the configuration (using Type.GetType()), and entry.Command is the SQL query. The specific entity type I'm having an issue with looks like this: public class FooCount { [Column(Name = "foo_id")] public Int32 FooId { get; set; } [Column(Name = "count")] public Int32 Count { get; set; } } The SQL query looks like this: select foo_id as foo_id, sum(count) as [count] from foo_aggregates group by foo_id order by foo_id For some reason, when the query is executed, the "Count" property ends up populated, but not the "FooId" property. I tried running the query myself, and the correct column names are returned, and the column names match up with what I've specified in my mapping attributes. Help!

  • DataGridView display row header cell

    - by Karl
    I'm trying to display a simple DataGridView linked to a DataTable and I want, ultimately, my first column in the DataTable to be the row header cell for the DataGridView. At this point I will settle for having any value in the row header cell. I can display the DataGridView with all my rows and columns, and with column header cells, but no row header cell. I check the value in the row.HeaderCell.Value, and the data I put there is there. I check row.HeaderCell.Displayed and it is false, but this is read only, so I can't make it true. How do I make the row header cell display? Here's a simple sample of what I've tried to get this to work: DataTable table = new DataTable(); for (int i = 0; i<10; i++) { table.Columns.Add(new DataColumn("column-" + i)); } for (int i = 0; i < 10; i++) { DataRow theRow = table.NewRow(); for (int j = 0; j < 10; j++) theRow[j] = i + "-" + j; table.Rows.Add(theRow); } dataGridView1.DataSource = table; dataGridView1.RowHeadersWidthSizeMode = System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders; int rowNumber = 1; foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.IsNewRow) continue; row.HeaderCell.Value = "Row " + rowNumber; rowNumber = rowNumber + 1; } dataGridView1.AutoResizeRowHeadersWidth( DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);

  • Roadmap to Android development

    - by Matthew
    Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

  • Why are floating point values so prolific?

    - by Kibbee
    So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster with floating point numbers, however, I can think of only a few cases that they actually the right data type would be using. If you sat back and think about every time you used a floating point value, how many times did you say, well, some error would be ok, as long as the result was a few microseconds faster. It really makes me think because Jeff was talking about NP completeness, and how heuristics give an answer that is kind of right. And well, computers shouldn't do that. They should give you the answer that is correct. Yet we see floating point values used in many applications where they are completely not valid. What really bugs me, isn't that floating point exists, but that in many languages, there isn't even a viable alternative, non-floating point, decimal value. A lot of programmers when doing financial applications have to fall back to storing the number of cents in an integer field. Which brings with it all kinds of other problems. Why do floats continue to be so prolific, even though they can't represent the real answer, and we expect computers to be accurate? [EDIT] Just to clarify, I was talking about Base 2 floating points, and not base 10 floating points. .Net offers the Decimal data type, which is a base 10 floating point value which offers a much better representation of the numbers we deal with on a daily basis in most computer programs. I find it hard to believe that even modern languages like Java don't support base 10 floating point values, unless you want to move into the realm of things like BigDecimal, which isn't really the right answer either in a lot of situations.

  • Finding perfect numbers in C# (optimization)

    - by paradox
    I coded up a program in C# to find perfect numbers within a certain range as part of a programming challenge . However, I realized it is very slow when calculating perfect numbers upwards of 10000. Are there any methods of optimization that exist for finding perfect numbers? My code is as follows: using System; using System.Collections.Generic; using System.Linq; namespace ConsoleTest { class Program { public static List<int> FindDivisors(int inputNo) { List<int> Divisors = new List<int>(); for (int i = 1; i<inputNo; i++) { if (inputNo%i==0) Divisors.Add(i); } return Divisors; } public static void Main(string[] args) { const int limit = 100000; List<int> PerfectNumbers = new List<int>(); List<int> Divisors=new List<int>(); for (int i=1; i<limit; i++) { Divisors = FindDivisors(i); if (i==Divisors.Sum()) PerfectNumbers.Add(i); } Console.Write("Output ="); for (int i=0; i<PerfectNumbers.Count; i++) { Console.Write(" {0} ",PerfectNumbers[i]); } Console.Write("\n\n\nPress any key to continue . . .

  • How can I convert this PHP script to Ruby? (build tree from tabbed string)

  • Castle Windsor with ASP.NET MVC 2 Areas

    - by Doug Shontz
    Been lurking for a few months and decided to jump in with a question. I am very new to Windsor and IoC in general. I can get Windsor to work with my MVC2 project with no problem. The project I am working on is a "portal" of multiple applications under one MVC2 project using the new Areas concept. In this scenario, each Area will actually be a separate application inside the "portal". We are doing this to effectively share a LOT of common code, views, authentication, and cross-application functionality. Many of our apps link to one another, so it made sense after discussing it to combine them into one project. What I am wondering how to do is actually allow different Areas to inject different concrete classes? In my limited understanding, the Application_Start is governing building the container and assigning it as the controller factory. I don't necessarily want to do all the injection at the application level. We have a config system where we have a config.xml at the root of every Area and those settings override any root settings. I would like to continue that trend by having the injections for each Area be read by the Area's config.xml (an inheritance similar to Webforms web.config where the config in a lower folder overrides settings in a parent folder). Example: I would have an ILogHandler which would need a different concrete implementation depending on which Area of the application I am in. So I would need to inject something different depending on where I am at in the application. I can easily do this using factories since each area could have it's own set of factories, but I am attempting to take this opportunity to learn about IoC and what the benefits/drawbacks are. Any help would be appreciated.

  • Cocoa NSStream works with SSL, with socks5, but not at the same time

    - by Evan D
    Upon connecting (to an FTP, at first without SSL) I run: NSArray *objects = [NSArray arrayWithObjects:@"proxy.ip", [NSNumber numberWithInt:1080], NSStreamSOCKSProxyVersion5, @"user", @"pass", nil]; NSArray *keys = [NSArray arrayWithObjects:NSStreamSOCKSProxyHostKey, NSStreamSOCKSProxyPortKey, NSStreamSOCKSProxyVersionKey, NSStreamSOCKSProxyUserKey, NSStreamSOCKSProxyPasswordKey, nil]; NSDictionary *proxyDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [iStream setProperty:proxyDictionary forKey:NSStreamSOCKSProxyConfigurationKey]; [iStream open]; same for iStream. This allows me to connect succesfully through a socks5 proxy. If I continue without setProperty:proxyDictionary... (socks5 disabled) I would tell the server to switch to SSL, and then successfully apply these settings to the in/output streams, thus giving me a SSL connection: NSMutableDictionary *settings = [NSMutableDictionary dictionaryWithCapacity:1]; [settings setObject:(NSString *)NSStreamSocketSecurityLevelTLSv1 forKey:(NSString *)kCFStreamSSLLevel]; // to allow selfsigned certificates: [settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; CFReadStreamSetProperty((CFReadStreamRef)iStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings); [iStream setProperty:NSStreamSocketSecurityLevelTLSv1 forKey:NSStreamSocketSecurityLevelKey]; same for oStream. All of which works fine if I disable socks5. If I turn it on (line 7 in the first snippit) I lose contact when applying the SSL settings. If I had to guess, I'd think it's losing some properties when applying (ssl) "settings"? Please help :) Evan

  • How do I add a confirmation popup on a button (GET POST action in MVC)?

    - by user54197
    I have a get/post/JSON function on an aspx page. This page adds data entered in a textbox to a table populated by javascript. When the user select the submit button. If the textbox is not empty, have a popup button telling the user the data in the textbox is not saved in the table. How do I have a confirm "ok/cancel" popup display on the post action in the Controller? I made a quick summary of what my code looks like. ... <% using (Html.BeginForm("AddName", "Name", FormMethod.Post, new { id = "AddNameForm" })) { %> ... <table id="displayNameTable" width= "100%"> <tr> <th colspan="3">Names Already Added</th> </tr> <tr> <td style="font-size:smaller;" class="name"></td> </tr> </table> ... <input name="Name" id="txtInjuryName" type="text" value="<%=test.Name %>" /> ... <input type="submit" name="add" value="Add"/> <% } %> <form id="form1" runat="server"> string confirmNext = ""; if (test.Name == "") { confirmNext = "return confirm('It seems you have a name not added.\n\nAre Continue?')"; }%> <input type="submit" name="getNext" value="Next" onclick="<%=confirmNext%>" /> </form>

  • Land of Lisp example question

    - by cwallenpoole
    I've read a lot of good things about Land of Lisp so I thought that I might go through it to see what there was to see. (defun tweak-text (lst caps lit) (when lst (let ((item (car lst)) (rest (cdr lst))) (cond ; If item = space, then call recursively starting with ret ; Then, prepend the space on to the result. ((eq item #\space) (cons item (tweak-text rest caps lit))) ; if the item is an exclamation point. Make sure that the ; next non-space is capitalized. ((member item '(#\! #\? #\.)) (cons item (tweak-text rest t lit))) ; if item = " then toggle whether we are in literal mode ((eq item #\") (tweak-text rest caps (not lit))) ; if literal mode, just add the item as is and continue (lit (cons item (tweak-text rest nil lit))) ; if either caps or literal mode = true capitalize it? ((or caps lit) (cons (char-upcase item) (tweak-text rest nil lit))) ; otherwise lower-case it. (t (cons (char-downcase item) (tweak-text rest nil nil))))))) (the comments are mine) (FYI -- the method signature is (list-of-symbols bool-whether-to-caps bool-whether-to-treat-literally) but the author shortened these to (lst caps lit).) But anyway, here's the question: This has (cond... (lit ...) ((or caps lit) ...)) in it. My understanding is that this would translate to if(lit){ ... } else if(caps || lit){...} in a C style syntax. Isn't the or statement redundant then? Is there ever a condition where the (or caps lit) condition will be called if caps is nil?

  • emacs indentation problem

    - by Gauthier
    I'm really trying to switch to emacs, but learning to setup the environment is a real pain. Everybody says it's worth it, so I just continue. I want my c code to be implemented that way: if(asdf) { asdr = 1; } Depending on the current standard (I know, don't get me started), could be: if(asdf) { asdr = 1; } I can't seem to change the indentation size from 2, it always looks like the GNU standard: if(asdf) { asdr = 1; } , which I dislike. Here is what I have put in my .emacs: ; Warn in C for while();, if(x=0), ... (global-cwarn-mode 1) ; no electric mode in c (c-toggle-electric-state -1) ; indent the current line only if the cursor is at the beginning of the line (setq-default c-tab-always-indent nil) (setq-default c-indent-level 4) (setq-default tab-width 4) (setq-default indent-tabs-mode nil) (setq-default c-basic-offset 4) (setq-default c-basic-indent 4) ; These commands I read about on the web, but they don't work? ;(highlight-tabs) ;(highlight-trailing_whitespace) This did not help, I have still the GNU indent. Anyone?

  • Is there any open source tool that automatically 'detects' email threading like Gmail?

    - by Chris W.
    For instance, if the original message (message 1) is... Hey Jon, Want to go get some pizza? -Bill And the reply (message 2) is... Bill, Sorry, I can't make lunch today. Jonathon Parks, CTO Acme Systems On Wed, Feb 24, 2010 at 4:43 PM, Bill Waters wrote: Hey John, Want to go get some pizza? -Bill In Gmail, the system (a) detects that message 2 is a reply to message 1 and turns this into a 'thread' of sorts and (b) detects where the replied portion of the message actually is and hides it from the user. (In this case the hidden portion would start at "On Wed, Feb..." and continue to the end of the message.) Obviously, in this simple example it would be easy to detect the "On <Date, <Name wrote:" or the "" character prefixes. But many email systems have many different style of marking replies (not to mention HTML emails). I get the feeling that you would have to have some damn smart string parsing algorithms to get anywhere near how good GMail's is. Does this technology already exist in an open source project somewhere? Either in some library devoted to this exclusively or perhaps in some open source email client that does similar message threading? Thanks.

  • Javascript/CSS rollover menus are patented and subject to licensing?

    - by Scott B
    Very interesting finding that a client brought to my attention today regarding javascript style rollover menus. They got a call from their legal dept that they need to change the manner in which their rollover menu is activated (at the risk of having to pay license to continue using the navigation technique). Its no April fools joke, apparently this is really happening. Apparently a company named Webvention LLC has obtained enforcement rights to a patent, U.S. Patent No. 5,251,294 - "Accessing, assembling, and using bodies of Information." A menu link, that when rolled over, expands to show a list of categorized, related links. Dropdown menus and slide-out menus are examples of this patented navigational methodology. A key component of this patent is that the dropdown/slide-out action must be initiated by a rollover or mouseover event. If the dropdown/slide-out action is initiated by any other event, such as a mouse-click event, then this behavior is not in violation of the patent. Anyone ever heard of this or know of the validity of its claims? Website is here: http://www.webventionllc.com/

  • NSFILEMANAGER CRASHING IN APP DELEGATE

    - by theiphoneguy
    I have this code in a method called from applicationDidFinishLaunching. It works in the simulator, but crashes on the iPhone. There are about 1,600 2KB mp3 files being copied in this operation. If I try to instantiate the app multiple times, it will eventually copy more each time until the app eventually will start without crashing. I am releasing everything I allocate. I have about 20GB disk space free on the iPhone. If I progressively comment out code and run it on the iPhone, the copyItemAtPath seems to be the suspect. (void)createCopyOfAudioFiles:(BOOL)force { @try { NSError *error; NSString *component; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *fileManager = [[NSFileManager alloc] init]; NSEnumerator *enumerator = [[[NSBundle mainBundle]pathsForResourcesOfType:@"mp3" inDirectory:nil] objectEnumerator]; while ((component = [enumerator nextObject]) != nil) { NSArray *temp = [component componentsSeparatedByString:@".app/"]; NSString *file = [NSString stringWithFormat:@"%@", [temp objectAtIndex:1]]; NSString *writableAudioPath = [documentsDirectory stringByAppendingPathComponent:file]; BOOL success = [fileManager fileExistsAtPath:writableAudioPath]; if (success &amp;&amp; !force) { continue; } else if (success &amp;&amp; force) { success = [fileManager removeItemAtPath:writableAudioPath error:&amp;error]; } success = [fileManager copyItemAtPath:component toPath:writableAudioPath error:&amp;error]; if (!success) { @throw [NSException exceptionWithName:[error localizedDescription] reason:[error localizedFailureReason] userInfo:nil]; } } [fileManager release]; } @catch (NSException *exception) { NSLog(@"%@", exception); @throw [NSException exceptionWithName:exception.name reason:exception.reason userInfo:nil]; } @finally { } }

  • Synchronizing an ERWin model with a Visual Studio 2008 GDR 2/2010 db project

    - by Grant Back
    I am looking for options to get our vast collection of DB objects across many DBs into source control (TFS 2010). Once we succeed here, we will work toward generating our alter scripts for a particular DB change via TFS build. The problem is, our data architecture group is responsible for maintaining the DB objects (excluding SPs), and they work within a model centric process, via ERWin. What this means, is that they maintain the DBs via ERWin models, and generate alters from them that are used to release changes. In order to achieve our goal of getting the DB objects (not just the ERWin models) into TFS, I believe the best option is to do this via Visual Studio DB projects. From what I can tell, there is very little urgency for CA to continue supporting an integration between ERWin and Visual Studio, that no longer works as of Visual Studio 2008 DB Ed. GDR. If I have been mislead in this regard, please feel free to set me straight. One potential solution is to: Perform changes in the ERWin model. Take the alter script generated from ERWin, and import the script into the appropriate Visual Studio DB project, updating the objects in the in the DB project Check the changed objects in the DB project into TFS. TFS Build executes to generate the alter scripts that will be used to push the changes through our release process. My question is, is this solution viable, or are there any other options?
