• Using the same class in both server and web service

  - by iTayb

  I have classes that are needed in both my web service and my server. For example, I have a class named Order that I'd like to send from my server to the web service and vice-versa. Problem is that the class in the server is Order and the one on the web service is localhost.Order, and it is impossible to convert between them, even though they are built from the very same code. Error is cannot convert from 'Order[]' to 'localhost.Order[]'. What can I do? Thank you very much.

So if one then of course it goes to case 1. If there are 2 opened then it moves the oldest down and puts the newest on top. etc etc. I have set it so that a max of 6 boxes can only be opened at one time. If anyone knows how i could also "slide" them down (kinda like an effect of jQuery) then that would also be, well awesome to know! :o) Any help/suggestions would be great! :o) David

• Customize VisualStudio syntax highlighting even more

  - by Alex K

  Hi everybody, I am wondering if it is possible to set VisualStudio IDE so it highlights private/protected/public variables of the class differently as well as change formatting on locals (i.e. variables that are either passed in or declared inside a function, like this). I did not find any such options in the normal Fonts and Colors menu of VS. Also a search on SO reveals that (at least as of 2 years ago) only add-ons provide such features. But is there a way to manually edit some file? Just because we don't get a nice UI to edit, doesn't mean underlying framework automatically doesn't support it. I mean add-ons have to plug into something to do their magic in the editor. Any insights into this issue? Thanks!

• SQL CE unspecified error

  - by Ruben Trancoso

  Hello, I did a project with MS SQL Server CE that when installed in the 'costumer' machine just raises an unspecified excpetion. Did some research and looks like I did everything mentioned. The dev env has sql compact 3.5 installed and sql tools for vs 2005. Using dotNet 3.5. But to make it run in de dev machine I need to add the sqlcese30, sqlceqp30, sqlceme and sqlcecompact30 dlls and its works fine. The setup project put dotNet 2.0 as dependecy and I also added the dlls but it raises the exception and I cannot see where or what it is. Its just a single 'unspecified error' message. please help :)

• VS2010 Using SQL Server 2000

  - by Chris M

  Is there a way to use the SQL Model (dbml) builder in VS2010 using SQLServer2000? It works fine in VSExpress2008 + VS2008 but throws an "Upgrade SQL to 2005" error in VS2010 which seems a tad unreasonable.

• Best package for basic web-based file manager

  - by alchemical

  I'm looking for a basic web-based file management application. It must have an affordable price, and fairly easy installation would be a plus. ASP.Net / IIS based would be easiest for me to work with. Basically, I'd like it to create a secure web site where myself and a few people can exchange various types of files, etc. I'm looking for a package I can install on my own server rather than a web-based service, as I think I can get more space at a good price point this way. I could go custom coding, but I figure this is such a generic need, there must be something already mature out there at a decent price. What has worked best for you?

• Install windows service "Service ... was not found on computer '.'."

  - by Chau

  I'm trying to create my first Windows Service in C# VS2010 and slowly discover how I should do things. But now I have reached a point, where I cannot install a new version of my service. My setup program tells me Error 1001. Service MyService was not found on computer '.'. --> The specified service does not exists as an installed service. The last part of the message is translated into english from danish. I cannot see the service in either the service list (services.msc) or in the registry. I have removed the left overs from a previous installation, so no traces here either. I have emptied the temporary folder under my windows account. Where do I locate the rest of the remains obstructing my installation of the service?

• VS2010 / Code Analysis: Turn off a rule for a project without custom ruleset....

  - by TomTom

  ...any change? The scenario is this: For our company we develop a standard how code should look. This will be the MS full rule set as it looks now. For some specific projects we may want to turn off specific rules. Simply because for a specific project this is a "known exception". Example? CA1026 - while perfectly ok in most cases, there are 1-2 specific libraries we dont want to change those. We also want to avoid having a custom rule set. OTOH putting in a suppress attribute on every occurance gets pretty convoluted pretty fast. Any way to turn off a code analysis warning for a complete assembly without a custom rule set? We rather have that in a specific file (GlobalSuppressions.cs) than in a rule set for maintenance reasons, and to be more explicit ;)

• Over-enthusiastic Intellisense in VS2010 - can I tweak it?

  - by CJM

  Since I have upgraded from VS2008 to VS2010, I've been having an increasingly infuriating battle with the Intellisense. For example, when specifying CSS styles, when I press Enter to start an new line, Intellisense (appropriately) lists available Styles to me. And if I select color and then type ':', it presents a list of color presets - often helpful. However, if I type in a space (I like them for readability) or if I type '#' to enter RGB values, it selected the default Intellisense selection, in this case inherits. Another example is in an ASP.NET page - say I am concatenating strings, I type myString =, I get an Intellisense pop-up. If I type space or '"' (to enter a literal) or '.' (so select a property or method within a WITH block), the Intellisense selects the first entry in the list. I can dismiss the Intellisense pop-ups with escape but it makes it incredibly slow to code. This behaviour is different to my VS2008 set-up. I can't seem to find any way to configure Intellisense to behave differently... I really only want it to select and Intellisense entry when I type or ... at least, certainly not when I type '"' or ' ' or '.'!

• How do you draw a line on a canvas in WPF that is 1 pixel thick.

  - by xarzu

  The method for drawing a line on a canvas in WPF that uses the line class actually draws a line that is two pixels thick: Line myLine = new Line(); myLine.Stroke = System.Windows.Media.Brushes.Black; myLine.X1 = 100; myLine.X2 = 140; // 150 too far myLine.Y1 = 200; myLine.Y2 = 200; myLine.StrokeThickness = 1; graphSurface.Children.Add(myLine); Microsoft might have decided to set a standard for line thickness and the minimum is 2 pixels thick when you set the strockThickness to 1, but when you already have rectangles drawn in XAML and even error fonts using WingDings, it is an obvious miss-match. How do you draw a line that is truly 1 pixel thick?

  I´m trying out entity framework included in VS2010 but ´ve hit a problem with my database/model generated from the graphical interface. When I do: user = dataset.UserSet.CreateObject(); user.Id = Guid.NewGuid(); dataset.UserSet.AddObject(user); dataset.SaveChanges(); {"Cannot insert the value NULL into column 'Id', table 'BarSoc2.dbo.UserSet'; column does not allow nulls.

• MySqlDateTime to System.DateTime conversion

  - by bowsa

  Ok I'm very new to databases and C# in general, but I'm using a piece of code that exports dataset data to an Excel file, and its taking issue with the date/time format. I'm using the MySQL connector so the rowtype is MySql.Data.Types.MySqlDateTime. Is there any quick way to convert it into System.DateTime so I can slot it straight into the case statement? Here's a link to the code I used, I copied it verbatim so I've not copied and pasted it here. It throws a MySql.Data.Types.MySqlDateTime not handled exception: Code Project Thanks in advance for any help.

• Delphi dbExpress and Interbase: Unicode migration steps and risks?

  - by mjustin

  Currently, our database uses Win1252 as the only character encoding. We will have to support Unicode in the database tables soon, which means we have to perform this migration for four databases and around 80 Delphi applications which run in-house in a 24/7 environment. Are there recommendations for database migrations to UTF-8 (or UNICODE_FSS) for Delphi applications? Some questions listed below. Many thanks in advance for your answers! are there tools which help with the migration of the existing databases (sizes between 250 MB and 2 GB, no Blob fields), by dumping the data, recreating the database with UNICODE_FSS or UTF-8, and loading the data back? are there known problems with Delphi 2009, dbExpress and Interbase 7.5 related to Unicode character sets? would you recommend to upgrade the databases to Interbase 2009 first? (This upgrade is planned but does not have a high priority) can we simply migrate the database and Delphi will handle the Unicode character sets automatically, or will we have to change all character field types in every Datamodule (dfm and source code) too? which strategy would you recommend to work on the migration in parallel with the normal development and maintenance of the existing application? The application runs in-house so development and database administration is done internally. Update: one problem I found now is that there are two different persistent field types for Unicode and non Unicode character fields. For the existing database, dbExpress creates TStringField objects. For the Unicode database fields, dbExpress creates (or expects!) TWideStringField objects. So we can not just change the database and the connection code page to Unicode. We also have to modify all datamodules to use the new field type. The modified datamodule however will not be backwards compatible.

• C# - Disable Dynamic Keyword

• Question - Should I use SPItemReceiver or SPEmailEventReceiver

  - by RiverStorm

  Hello, I have custom SharePoint Document Library which I use to upload spreadsheet data into a database. When a spreadsheet is uploaded, the SPItemReceiver triggers, and upload the data. Now, I would like to add an incoming email feature to the document library. My question is...after the document library has received the spreadsheet by email. Should I use the override-able method EmailReceived of the SPEmailEventReceiver to process the data in the spreadsheet or still use the SPItemReceiver? I gather I could use either, but I would like to know your opinion which is better and why. Thanks in advance

• Performing dynamic sorts on EF4 data

  - by Jaxidian

  I'm attempting to perform dynamic sorting of data that I'm putting into grids into our MVC UI. Since MVC is abstracted from everything else via WCF, I've created a couple utility classes and extensions to help with this. The two most important things (slightly simplified) are as follows: public static IQueryable<T> ApplySortOptions<T, TModel, TProperty>(this IQueryable<T> collection, IEnumerable<ISortOption<TModel, TProperty>> sortOptions) where TModel : class { var sortedSortOptions = (from o in sortOptions orderby o.Priority ascending select o).ToList(); var results = collection; foreach (var option in sortedSortOptions) { var currentOption = option; var propertyName = currentOption.Property.MemberWithoutInstance(); var isAscending = currentOption.IsAscending; if (isAscending) { results = from r in results orderby propertyName ascending select r; } else { results = from r in results orderby propertyName descending select r; } } return results; } public interface ISortOption<TModel, TProperty> where TModel : class { Expression<Func<TModel, TProperty>> Property { get; set; } bool IsAscending { get; set; } int Priority { get; set; } } I've not given you the implementation for MemberWithoutInstance() but just trust me in that it returns the name of the property as a string. :-) Following is an example of how I would consume this (using a non-interesting, basic implementation of ISortOption<TModel, TProperty>): var query = from b in CurrentContext.Businesses select b; var sortOptions = new List<ISortOption<Business, object>> { new SortOption<Business, object> { Property = (x => x.Name), IsAscending = true, Priority = 0 } }; var results = query.ApplySortOptions(sortOptions); As I discovered with this question, the problem is specific to my orderby propertyName ascending and orderby propertyName descending lines (everything else works great as far as I can tell). How can I do this in a dynamic/generic way that works properly?

• TArray<Byte> VS TBytes VS PByteArray

  - by Ken Bourassa

  Those 3 types are very similar... TArray is the generic version of TBytes. Both can be casted to PByteArray and used as buffer for calls to Windows API. (with the same restrictions as string to Pchar). What I would like to know: Is this behavior "by design" or "By Implementation". Or more specifically, could it break in future release?

• Error displaying a WinForm in Design mode with a custom control on it.

  - by George

  I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run. It may have something to do with namespaces. The original namespace was simply "Design" and this was ambiguous and conflicting so i decided to rename it. I think that's when my problems began.

• Why are access modifiers on web service proxy methods important

  - by cand

  I'm creating interface to an external web service with C# client generated from WSDL. And in this client class I have methods with signature like: public ResponseType InvokeMethod(RequestType request). I want to change its access modifier to protected, but then web service responds with "web service method name is not valid" exception. Do You know why is that so? I understand that maintaining method name can be important for some reasons, but why can't I change this access modifier? Shouldn't it be a matter of my code what access I want to give to this method? Thanks for all the answers in advance.
