• Convert string to decimal retaining the exact input format

  - by Brett

  Hi All, I'm sure this is a piece of cake but I'm really struggling with something that seems trivial. I need to check the inputted text of a textbox on the form submit and check to see if it's within a desired range (I've tried a Range Validator but it doesn't work for some reason so I'm trying to do this server-side). What I want to do is: Get the value inputted (eg. 0.02), replace the commas and periods, convert that to a decimal (or double or equivalent) and check to see if it's between 0.10 and 35000.00. Here's what I have so far: string s = txtTransactionValue.Text.Replace(",", string.Empty).Replace(".", string.Empty); decimal transactionValue = Decimal.Parse(s); if (transactionValue >= 0.10M && transactionValue <= 35000.00M) // do something If I pass 0.02 into the above, transactionValue is 2. I want to retain the value as 0.02 (ie. do no format changes to it - 100.00 is 100.00, 999.99 is 999.99) Any ideas? Thanks in advance, Brett

• Why Java language does not offer a way to declare getters and setters of a given "field" through ann

  - by zim2001

  I actually happily design and develop JEE Applications for quite 9 years, but I realized recently that as time goes by, I feel more and more fed up of dragging all these ugly bean classes with their bunch of getters and setters. Considering a basic bean like this : public class MyBean { // needs getter AND setter private int myField1; // needs only a getter, no setter private int myField2; // needs only a setter, no getter private int myField3; /** * Get the field1 * @return the field1 */ public int getField1() { return myField1; } /** * Set the field1 * @param value the value */ public void setField1(int value) { myField1 = value; } /** * Get the field2 * @return the field2 */ public int getField2() { return myField2; } /** * Set the field3 * @param value the value */ public void setField3(int value) { myField3 = value; } } I'm dreaming of something like this : public class MyBean { @inout(public,public) private int myField1; @out(public) private int myField2; @in(public) private int myField3; } No more stupid javadoc, just tell the important thing... It would still be possible to mix annotation and written down getters or setters, to cover cases when it should do non-trivial sets and gets. In other words, annotation would auto-generate the getter / setter code piece except when a literate one is provided. Moreover, I'm also dreaming of replacing things like that : MyBean b = new MyBean(); int v = b.getField1(); b.setField3(v+1); by such : MyBean b = new MyBean(); int v = b.field1; b.field3 = v+1; In fact, writing "b.field1" on the right side of an expression would be semantically identical to write "b.getField1()", I mean as if it has been replaced by some kind of a preprocessor. It's just an idea but I'm wondering if I'm alone on that topic, and also if it has major flaws. I'm aware that this question doesn't exactly meet the SO credo (we prefer questions that can be answered, not just discussed) so I flag it community wiki...

• Validating Application Settings Key Values in Isolated Storage for Windows Phone Applications

  - by Martin Anderson

  Hello everyone. I am very new at all this c# Windows Phone programming, so this is most probably a dumb question, but I need to know anywho... IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings; if (!appSettings.Contains("isFirstRun")) { firstrunCheckBox.Opacity = 0.5; MessageBox.Show("isFirstRun not found - creating as true"); appSettings.Add("isFirstRun", "true"); appSettings.Save(); firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else { if (appSettings["isFirstRun"] == "true") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else if (appSettings["isFirstRun"] == "false") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = false; } else { firstrunCheckBox.Opacity = 0.5; } } I am trying to firstly check if there is a specific key in my Application Settings Isolated Storage, and then wish to make a CheckBox appear checked or unchecked depending on if the value for that key is "true" or "false". Also I am defaulting the opacity of the checkbox to 0.5 opacity when no action is taken upon it. With the code I have, I get the warnings Possible unintended reference comparison; to get a value comparison, cast the left hand side to type 'string' Can someone tell me what I am doing wrong. I have explored storing data in an Isolated Storage txt file, and that worked, I am now trying Application Settings, and will finally try to download and store an xml file, as well as create and store user settings into an xml file. I want to try understand all the options open to me, and use which ever runs better and quicker

• Publishing to live website

  - by Alienfluid

  Hey there, My friend and I are collaborating on a ASP.NET powered website. To develop it locally, we use Visual Web Developer Express (good enough for our needs). Subversion (using Tortoise SVN) is our source control of choice with the repository residing on Unfuddle.com. We run into problems when we need to update the live site - since there's no version control on it. Currently we use the "Copy to Website" feature in VWD which copies the files using FTP. Here are some problems: VWD only keeps track of files uploaded by one user, so if the other user uploads a newer version of a file to the live site, VWD on my side cannot tell whether the live version of the file is newer or mine is. There's no way to tell whether all the latest changes are available on the live site. We have to be careful not to party all over the shared web.config file since the other user's local DB settings are different from mine, and of course, the live DB settings are a whole other story! What do you guys use to publish to a live site? Does anything out there tie into Subversion so that we can automate the process and always guarantee that the live site is synced to a change list number? Also, how do you manage the different web.config file settings? Thanks!

• iPhone: TableView inside UIScrollview, show vaccillating scrollbars around

  - by karim

  Hi, I have added some table and other vies in a scrollview. scrolling in tables are working fine. But in the parent scrollview, when scrolling, a vacillating vertical scrollbars are shown, sometimes it even come to the middle of the screen. sometime show at the left side of the screen. and not limited to the vertical scrollbar region. When I set tje showsVerticalScrollIndicator = NO, it is not shown. But do you know why the scrollbar is moving around. DashboardView is a subclass of UIScrollView. dashboard=[[DashboardView alloc] initWithFrame:fullScreenRect]; dashboard.contentSize = CGSizeMake(320,700); // must do! dashboard.showsVerticalScrollIndicator = YES; dashboard.bounces = YES; self.view = dashboard; @implementation DashboardView (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } (void)drawRect:(CGRect)rect { // Drawing code } (void) layoutSubviews{ NSArray *views = self.subviews; [UIView beginAnimations:@"CollapseExpand" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; UIView *view = [views objectAtIndex: 0]; CGRect rect = view.frame; for (int i = 1; i < [views count]; i++ ) { view = [views objectAtIndex:i]; view.frame = CGRectMake(rect.origin.x, rect.origin.y + rect.size.height, view.frame.size.width, view.frame.size.height); rect = view.frame; } [UIView commitAnimations]; }

• Can I write this regex in one step?

  - by Marin Doric

  This is the input string "23x +y-34 x + y+21x - 3y2-3x-y+2". I want to surround every '+' and '-' character with whitespaces but only if they are not allready sourrounded from left or right side. So my input string would look like this "23x + y - 34 x + y + 21x - 3y2 - 3x - y + 2". I wrote this code that does the job: Regex reg1 = new Regex(@"\+(?! )|\-(?! )"); input = reg1.Replace(input, delegate(Match m) { return m.Value + " "; }); Regex reg2 = new Regex(@"(?<! )\+|(?<! )\-"); input = reg2.Replace(input, delegate(Match m) { return " " + m.Value; }); explanation: reg1 // Match '+' followed by any character not ' ' (whitespace) or same thing for '-' reg2 // Same thing only that I match '+' or '-' not preceding by ' '(whitespace) delegate 1 and 2 just insert " " before and after m.Value ( match value ) Question is, is there a way to create just one regex and just one delegate? i.e. do this job in one step? I am a new to regex and I want to learn efficient way.

• Best practice when using WebMethods and session

  - by Abdel Olakara

  Hi all, I want to reduce postback in one of my application page and use ajax instead. I used the WebMethod to do so.. I have a static WebMethod that needs to access the session variables and modify. and on the client side, i am calling this method using jQuery. I tried accessing the session as follows: [WebMethod] public static void TestWebMethod() { if (HttpContext.Current.Session["pitems"] != null) { log.Debug("Using the existing list"); Product prod = (Product)HttpContext.Current.Session["pitems"]; List<Configs> confs = cart.GetConfigs(); foreach (Configs citem in confis) { log.Info(citem.Description); } } log.Info("Inside the method!"); } The values are displayed correctly and seems to work.. but i would like to know if this practice is allowed as the method is a static methods and would like to know how it will behave if multiple people access the application. I would also like to know how developers do these kind of tasks in ASP if this is not the right method. Thanks in advance for your suggestions and ideas, Abdel Olakara

• Secure Password Storage and Transfer

  - by Andras Zoltan

  I'm developing a new user store for my organisation and am now tackling password storage. The concepts of salting, HMAC etc are all fine with me - and want to store the users' passwords either salted and hashed, HMAC hashed, or HMAC salted and hashed - not sure what the best way will be - but in theory it won't matter as it will be able to change over time if required. I want to have an XML & JSON service that can act as a Security Token Service for client-side apps. I've already developed one for another system, which requires that the client double-encrypts a clear-text password using SHA1 first and then HMACSHA1 using a 128 unique key (or nonce) supplied by the server for that session only. I'd like to repeat this technique for the new system - upgrading the algo to SHA256 (chosen since implementations are readily available for all aforementioned platforms - and it's much stronger than SHA1) - but there is a problem. If I'm storing the password as a salted hash in the user-store, the client will need to be sent that salt in order to construct the correct hash before being HMACd with the unique session key. This would completely go against the point of using a salt in the first place. Equally, if I don't use salt for password storage, but instead use HMAC, it's still the same problem. At the moment, the only solution I can see is to use naked SHA256 hashing for the password in the user store, so that I can then use this as a starting point on both the server and the client for a more secure salted/hmacd password transfer for the web service. This still leaves the user store vulnerable to a dictionary attack were it ever to be accessed; and however unlikely that might be - assuming it will never happen simply doesn't sit well with me. Greatly appreciate any input.

• Calling SubmitChanges on DataContext does not update database.

  - by drasto

  In C# ASP.NET MVC application I use Link to SQL to provide data for my application. I have got simple database schema like this: In my controller class I reference this data context called Model (as you can see on the right side of picture in properties) like this: private Model model = new Model(); I've got a table (List) of Series rendered on my page. It renders properly and I was able to add delete functionality to delete Series like this: public ActionResult Delete(int id) { model.Series.DeleteOnSubmit(model.Series.SingleOrDefault(s => s.ID == id)); model.SubmitChanges(); return RedirectToAction("Index"); } Where appropriate action link looks like this: <%: Html.ActionLink("Delete", "Delete", new { id=item.ID })%> Also create (implemented in similar way) works fine. However edit does not work. My edit looks like this: public ActionResult Edit(int id) { return View(model.Series.SingleOrDefault(s => s.ID == id)); } [HttpPost] public ActionResult Edit(Series series) { if (ModelState.IsValid) { UpdateModel(series); series.Title = series.Title + " some string to ensure title has changed"; model.SubmitChanges(); return RedirectToAction("Index"); } I have controlled that my database has a primary key set up correctly. I debugged my application and found out that everything works as expected until the line with model.SubmitChanges();. This command does not apply the changes of Title property(or any other) against the database. Please help.

• Can SOTI's MobiControl software interfere with an ASP.Net web service?

  - by MusiGenesis

  We have a set of WinMo (5.0) devices running a .NET CF application that talks to an ASP.Net web service running on a server. The devices connect to the network either via ActiveSync through a networked PC or directly to the network via an Ethernet dongle. In our development environment, the communication between devices and web service is 100% reliable. In our production environment, the communications are failing erratically and unpredictably. Sometimes calls to the web service (even to a simple test call that just returns a boolean) begin failing every time on a particular device, with the error message "Could not establish connection to network." This is usually fixed by flip-flopping the selected combo box values on the SETTINGS | NETWORKS screen. Sometimes calls on a particular device begin failing with a generic "WebException" message. The fix for this problem (so far) is either to reset the device (i.e. reinstall the OS) or else it just can't be fixed on some devices. To the best of our knowledge, everything about the DEV and PROD systems are the same (same server and device specs). The most obvious difference to us is that the PROD devices are all controlled by SOTI's MobiControl (which is server-side software that communicates with a SOTI client application installed on each device), whereas our DEV environment does not have SOTI installed anywhere (obviously we should have it there as well - long story). Does anybody have any experience with SOTI MobiControl and/or know of any documented problems where SOTI interferes with other communication mechanisms on a device?

• Best Practice for Uploading Many (2000+) Images to A Server

  - by bob

  Hello, I have a general question about this. When you have a gallery, sometimes people need to upload 1000's of images at once. Most likely, it would be done through a .zip file. What is the best way to go about uploading this sort of thing to a server. Many times, server have timeouts etc. that need to be accounted for. I am wondering what kinds of things should I be looking out for and what is the best way to handle a large amount of images being uploaded. I'm guessing that you would allow a user to upload a zip file (assuming the timeout does not effect you), and this zip file is uploaded to a specific directory, lets assume in this case a directory is created for each user in the system. You would then unzip the directory on the server and scan the user's folder for any directories containing .jpg or .png or .gif files (etc.) and then import them into a table accordingly. I'm guessing labeled by folder name. What kind of server side troubles could I run into? I'm aware that there may be many issues. Even general ideas would be could so I can then research further. Thanks! Also, I would be programming in Ruby on Rails but I think this question applies accross any language.

• SeriesInterpolate - removing data at start of array

  - by Allan Jardine

  Hello all, I've been experimenting with Flex Charts (in Flash Builder 4) recently, but have run into one area which didn't quite work as I was expecting. Specifically, when adding and removing a data point from an array, with SeriesInterpolate set. I've put up three examples, as I expect these will make a lot more sense than me trying to explain it with words only!: http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-Add.swf - Clicking the button in the top right adds a new data point to the end of the data array, and the chart is smoothly updated (almost smoothly there is a 1px shift when animating which is odd...) http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-Delete.swf - Clicking the button (which is now labelled incorrectly) will remove the item at the start of the data array - but the chart draws this as if it were removing the end element. http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-AddDelete.swf - This is sort of what I'm eventually aiming for - a smooth side scroll chart, where new data is added at the end and the old data is sifted off the front. However the delete behaviour makes this look a bit odd. Does anyone know if there is a way to get the smooth transition I'm looking with SeriesInterpolate? Or is it possible to implement a custom transition? Many thanks, Allan

• LPX-00607 for ora:contains in java but not sqlplus

  - by Windle

  Hey all, I am trying to doing some sql querys out of Oracle 11g and am having issues using ora:contains. I am using spring's jdbc impl and my code generates the sql statement: select * from view_name where column_a = ? and column_b = ? and existsNode(xmltype(clob_column), 'record/name [ora:contains(text(), "name1") 0]', 'xmlns:ora="http://xmlns.oralce.com/xdb"') = 1 I have removed the actual view / column names obviously, but when I copy that into sqlplus and substitute in random values, the select executes properly. When I try to run it in my DAO code I get this stack trace: org.springframework.jdbc.UncatergorizedSQLException: PreparedStatementCallback; uncatergorizedSQLException for SQL [the big select above]; SQL state [99999]; error code [31011]; ORA-31011: XML parsing failed. ORA-19202: Error occured in XML processing LPX-00607: Invalid reference: 'contains' ;nested exception is java.sql.SQLException: ORA-31011: XML parsing failed ORA-19202: Error occured in XML processing LPX-00607: Invalid reference: 'contains' (continues on like this for awhile....) I think it is worth mentioning that I am using maven and it is possible I am missing some dependency that is required for this. Sorry the post is so long, but I wanted to err on the side of too much info. Thanks for taking the time to read this at least =) -Windle

• JVM/CLR Source-compatible Language Options

  - by Nathan Voxland

  I have an open source Java database migration tool (http://www.liquibase.org) which I am considering porting to .Net. The majority of the tool (at least from a complexity side) is around logic like "if you are adding a primary key and the database is Oracle use this SQL. If database is MySQL use this SQL. If the primary key is named and the database is Postgres use this SQL". I could fork the Java codebase and covert it (manually and/or automatically), but as updates and bug fixes to the above logic come in I do not want to have to apply it to both versions. What I would like to do is move all that logic into a form that can be compiled and used by both Java and .Net versions naively. The code I am looking to convert does not contain any advanced library usage (JDBC, System.out, etc) that would vary significantly from Java to .Net, so I don't think that will be an issue (at worst it can be designed around). So what I am looking for is: A language in which I can code common parts of my app in and compile it into classes usable by the "standard" languages on the target platform Does not add any runtime requirements to the system Nothing so strange that it scares away potential contributors I know Python and Ruby both have implementations on for the JVM and CLR. How well do they fit my requirements? Has anyone been successful (or unsuccesful) using this technique for cross-platform applications? Are there any gotcha's I need to worry about?

• QueryString malformed after URLDecode

  - by pdavis

  I'm trying to pass in a Base64 string into a C#.Net web application via the QueryString. When the string arrives the "+" (plus) sign is being replaced by a space. It appears that the automatic URLDecode process is doing this. I have no control over what is being passed via the QueryString. Is there any way to handle this server side? Example: http://localhost:3399/Base64.aspx?VLTrap=VkxUcmFwIHNldCB0byAiRkRTQT8+PE0iIHBsdXMgb3IgbWludXMgNSBwZXJjZW50Lg== Produces: VkxUcmFwIHNldCB0byAiRkRTQT8 PE0iIHBsdXMgb3IgbWludXMgNSBwZXJjZW50Lg== People have suggested URLEncoding the querystring: System.Web.HttpUtility.UrlEncode(yourString) I can't do that as I have no control over the calling routine (which is working fine with other languages). There was also the suggestion of replacing spaces with a plus sign: Request.QueryString["VLTrap"].Replace(" ", "+"); I had though of this but my concern with it, and I should have mentioned this to start, is that I don't know what other characters might be malformed in addition to the plus sign. My main goal is to intercept the QueryString before it is run through the decoder. To this end I tried looking at Request.QueryString.toString() but this contained the same malformed information. Is there any way to look at the raw QueryString before it is URLDecoded? After further testing it appears that .Net expects everything coming in from the QuerString to be URL encoded but the browser does not automatically URL encode GET requests.

• Game login authentication and security.

  - by Charles

  First off I will say I am completely new to security in coding. I am currently helping a friend develop a small game (in Python) which will have a login server. I don't have much knowledge regarding security, but I know many games do have issues with this. Everything from 3rd party applications (bots) to WPE packet manipulation. Considering how small this game will be and the limited user base, I doubt we will have serious issues, but would like to try our best to limit problems. I am not sure where to start or what methods I should use, or what's worth it. For example, sending data to the server such as login name and password. I was told his information should be encrypted when sending, so in-case someone was viewing it (with whatever means), that they couldn't get into the account. However, if someone is able to capture the encrypted string, wouldn't this string always work since it's decrypted server side? In other words, someone could just capture the packet, reuse it, and still gain access to the account? The main goal I am really looking for is to make sure the players are logging into the game with the client we provide, and to make sure it's 'secure' (broad, I know). I have looked around at different methods such as Public and Private Key encryption, which I am sure any hex editor could eventually find. There are many other methods that seem way over my head at the moment and leave the impression of overkill. I realize nothing is 100% secure. I am just looking for any input or reading material (links) to accomplish the main goal stated above. Would appreciate any help, thanks.

• Cannot connect Linux XAMPP PHP to MS SQL database.

  - by Jim

  I've searched many sites without success. I'm using XAMPP 1.7.3a on Ubuntu 9.1. I have used the methods found at http://www.webcheatsheet.com/PHP/connect_mssql_database.php, they all fail. I am able to "connect" with a linked database through MS Access, however, that is not an acceptable solution as not all users will have Access. The first method (at webcheatsheet) uses mssql_connect, et.al. but I get this error from the mssql_connect() call: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: [my server] in [my code] [my server] is the server address, I have used both the host name and the IP address. [my code] is a reference to the file and line number in my .php file. Is there a log file somewhere that would have more information about the failure, both on my machine and the MS SQL server? We do not have a bona-fide DBA, so I will need specific information to pass on if the issue seems to be on the server side. All assistance is appreciated, including RTFM when the location of the M is provided! Thanks

• Question about mixing MEF and Unity

  - by Dave

  I'm finally diving into Unity head first, and have run into my first real problem. I've been gradually changing some things in my app from being MEF-resolved to Unity-resolved. Everything went fine on the application side, but then I realized that my plugins were not being loaded. I started to look into this issue, and I believe it's a case where MEF and Unity don't mix. Plugins are loaded by MEF, but each plugin needs to get access to the shared libraries in my application, like app preferences, logging, etc. Initially, my plugin constructor had the ImportingConstructor attribute. I then replaced it with InjectionConstructor so that Unity could resolve its shared library dependencies. But because I did that, MEF no longer loaded it! Then I used both attributes, which compiled, but then I got a composition error (MEF). I figured that this was because the constructor takes a parameter that was once resolved by a MEF Import, so I removed all parameters. As expected, now MEF was able to load my plugin, but because the constructor needs to call into the interface that was once passed in, construction fails. So now I'm at a point where I can get MEF to start to load my plugin, but can't do anything with it because the plugin relies on shared libraries that are registered with Unity. For those of you that have successfully mixed MEF and Unity, how do you go about resolving the references to the shared libraries with Unity? It seems like a catch-22, where in order to have Unity work with the plugin, I'd have to create the plugin via Resolve, but then it's impossible to use MEF. UPDATE I can work around this problem by using an ImportingConstructor for the plugin that takes an IUnityContainer, and then call Resolve for each interface that I need, but although it works, it is incredibly lame to do it this way, as this would require all plugin authors to remember to save a reference to the passed in IUnityContainer...

• jquery: prepopulating autocomplete fields

  - by David Tildon

  I'm using the tokenizing autocomplete plugin for jquery ( http://loopj.com/2009/04/25/jquery-plugin-tokenizing-autocomplete-text-entry ). I mostly use Ruby, and I'm really unfamiliar with javascript, though. My basic setup looks like this, and works fine for a new, blank form: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search" }); }); The problem comes when I try to prepopulate it, like for an edit page. I'm trying to do something like this (where the "#tag_ids_field" text box contains the JSON when the page is loaded - that way is just cleaner on the application side of things). $(document).ready(function () { var tags = $("#tag_ids_field").html(); $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: tags }); }); However, when the page loads I see that it's just filled with hundreds of entries that read 'undefined'. I get this even if I take the JSON output that Rails provides and try sticking it right in the .js file: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: "[{\"id\":\"44\",\"name\":\"omnis sit impedit et numquam voluptas enim\"},{\"id\":\"515\",\"name\":\"deserunt odit id doloremque reiciendis aliquid qui vel\"},{\"id\":\"943\",\"name\":\"exercitationem numquam possimus quasi iste nisi illum\"}]" }); }); That's obviously not a solution, I just tried it out of frustration and I get the same behavior. My two questions: One, why are my text boxes being filled with "undefined" tags when I try to prepopulate, and how can I get them to prepopulate successfully? Two, I'm planning on having many autocomplete fields like this on the same page (for when several records are edited at once - they all query the same place). How can I make each autocomplete field take it's prepopulated values from it's own textbox? Something like (applying these settings to all input boxes with a certain class, not just the one of a particular id): $(document).ready(function () { $(".tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: (the contents of that particular ".tag_ids_field" input box) }); });

• Class/Model Level Validation (as opposed to Property Level)? (ASP.NET MVC 2.0)

  - by Erx_VB.NExT.Coder

  Basically, what the title says. I have several properties that combine together to really make one logical answer, and i would like to run a server-side validation code (that i write) which take these multiple fields into account and hook up to only one validation output/error message that users see on the webpage. I looked at scott guthries method of extending an attribute and using it in yoru dataannotations declarations, but, as i can see, there is no way to declare a dataannotations-style attribute on multiple properties, and you can only place the declarations (such as [Email], [Range], [Required]) over one property :(. i have looked at the PropertiesMustMatchAttribute in the default mvc 2.0 project that appears when you start a new project, this example is as useful as using a pair of pins to check your motor oil - useless! i have tried this method, however, creating a class level attribute, and have no idea how to display the error from this in my aspx page. i have tried html.ValidationMessage("ClassNameWhereAttributeIsAdded") and a variety of other thing, and it has not worked. and i should mention, there is NOT ONE blog post on doing validation at this level - despite this being a common need in any project or business logic scenario! can anyone help me in having my message displayed in my aspx page, and also if possible a proper document or reference explaining validation at this level?

• Making that move from junior > mid level

  - by dotnetdev

  Hi, Before I start, I know there is another thread about this very issue (http://stackoverflow.com/questions/2352874/moving-from-junior-developer-to-mid-level). I am in this very same situation, but of course every person and the company/employment-history is not the same. In my current company, I have not done one piece of coding from start to finish with the oversight of my manager and a Project Manager to manage the work/deadlines etc. I am basically an odd-jobs type of guy. The coding I do is on the side to whatever boring spreadsheet/word document I have to write. Very illogical that you're a coder and you're doing it in secret. In another job I had for 3 months (Was made redundant), it required 1 years experience, perhaps because of the fact I was the sole developer. It wasn't too hard, but then I was solely responsible and I learnt a lot from that. I had 2 other 3 months jobs (contracts), so I have been working for 1 year 9 months. I know found a job which I'm in the last stage for, which needs 3 years .NET experience and 2 years Sharepoint. How can I know if I am ready for this job? My current job has been going on for 1 year, but it doesn't mean squat apart from explaining how I have spent my time. It does not tell me what level I am at (apart from the huge skills gap I have opened up against my peers because I practise at home). So 1 year of doing nothing at work, but 1 year of doing loads at home. In fact, I take 1 week off and do more at home then in the company since I started. How can I know if I am ready for such a job? I am generally very confident given all I've achieved in coding, but I have no idea what a job with this sort of experience entails (what day-to-day-problems I would be facing). Is there any advice on how to handle this transition? Thanks

• Deserializing a FileStream on Client using WCF

  - by Grandpappy

  I'm very new to WCF, so I apologize in advance if I misstate something. This is using .NET 4.0 RC1. Using WCF, I am trying to deserialize a response from the server. The base response has a Stream as its only MessageBodyMember. public abstract class StreamedResponse { [MessageBodyMember] public Stream Stream { get; set; } public StreamedResponse() { this.Stream = Stream.Null; } } The derived versions of this class are actually what's serialized, but they don't have a MessageBodyMember attribute (they have other base types such as int, string, etc listed as MessageHeader values). [MessageContract] public class ChildResponse : StreamedResponse { [DataMember] [MessageHeader] public Guid ID { get; set; } [DataMember] [MessageHeader] public string FileName { get; set; } [DataMember] [MessageHeader] public long FileSize { get; set; } public ChildResponse() : base() { } } The Stream is always a FileStream, in my specific case (but may not always be). At first, WCF said FileStream was not a known type, so I added it to the list of known types and now it serializes. It also appears, at first glance, to deserialize it on the client's side (it's the FileStream type). The problem is that it doesn't seem to be usable. All the CanRead, CanWrite, etc are false, and the Length, Position, etc properties throw exceptions when being used. Same with ReadByte(). What am I missing that would keep me from getting a valid FileStream?

• Redraw and flicker issues

  - by AngryHacker

  I have an Outlook style app. So basically I have a sidebar on the left and on the right I have a panel control (pnlMainBody) that hosts content. The content is typically a user control that I add to the panel when user clicks appropriate button in the side bar. The way I add the user control to the panel is as follows: // _pnlEmails is the User Control that I am adding to the panel _pnlEmails = new pnlEmails(); _pnlEmails.Dock = DockStyle.Fill; this.pnlMainBody.Controls.Add(_pnlEmails); Some of the user controls that I add to the main panel are quite complex UI-wise. So when this.pnlMainBody.Controls.Add(_pnlEmails); fires, I see the control appear on the screen, then it resizes itself to fill the body of the panel control. It's quite ugly actually, so I was wondering whether there is a way to not show the resizing until it's actually done resizing? I've tried setting the user control's .Visible to false. I've tried doing .SuspendLayout, all to no avail. Is there a way to do this so the screen transitions are smooth?

• CSS box shadow on container div causes scrollbars

  - by kaile

  I have a website with the following setup: <div id="container"> <div id="header"></div> <div id="content"></div> <div id="clearfooter"></div> </div> <div id="footer"></div> I use the clearfooter and a footer outside the container to keep the footer at the bottom of the page when there isn't enough content. My problem is that I would like to apply a box shadow on the container div in the following way: #container {width:960px; min-height:100%; margin:0px auto -32px auto; position:relative; padding:0px; background-color:#e6e6e6; -moz-box-shadow: -3px 0px 5px rgba(0,0,0,.8), 3px 0px 5px rgba(0,0,0,.8);} #header {height:106px; position:relative;} #content {margin:0px; padding:10px 30px 10px 30px; position:relative;} #clearFooter {height:32px; clear:both; display:block; padding:0px; margin:0px;} #footer {height:32px; padding:0px; position:relative; width:960px; margin:0px auto 0px auto;} As you can see its a drop shadow on on each side of the container div. However, in doing this, when the content doesn't take up the full height, there are still scroll bars caused by the shadow pushing past the bottom of the footer due to the blur. Is there some way of preventing the shadow from going past the edge of the container div and causing a scrollbar? Thanks for your help!
