  • Array index is not accessable because it is Friend

    - by user3738194
    I am getting and error when I bring my code into another project. In a blank project it works fine, I really have no idea how to get around it, here is the error Error 1 'System.Data.Index' is not accessible in this context because it is 'Friend'. Dim DataString As String = txtAdvancedCommand.Text ' Create an array containing from each letter in Textbox Dim charArray() As Char = DataString.ToCharArray For index = 0 To charArray.GetUpperBound(0) <-----ERROR on word index Try 'Now lets send the data If SerialPort.IsOpen Then SerialPort.Write(charArray(index) & vbCrLf) <-----ERROR on word index Else ConnectSerial() SerialPort.Write(charArray(index) & vbCrLf) <-----ERROR on word index End If Catch e As Exception txtLog.AppendText(e.Message & vbCrLf) End Try Next now the project I am bringing into has a DLL and I suspect it has something to do with it, I cannot get the source code to the DLL so is there another way around this?

  • Not loading the object caused EF4 (code first) to remove the relationship

    - by Lavinski
    Firstly this is a EF4: Code First - Property Loading question. I'm loading an object like so var item = Context.Table.Find( update.Identifier ); This object has a property Relationship so a table has a Relationship object. Now i'm updating my item but my Relationship object is not toched (and therefore not lazy loaded). Now here's the problem .. I save my item and my relationship to the Relationship object is deleted, apparently the model thinks i set it to null. However it all works if I look at the property before saving. So I'm looking into LoadProperty or doing a query and using Include. Has anyone else come across this issue and how did you get around it?

  • initializing properties with private sets in .Net

    - by Martin Neal
    public class Foo { public string Name { get; private set;} // <-- Because set is private, } void Main() { var bar = new Foo {Name = "baz"}; // <-- This doesn't compile /*The property or indexer 'UserQuery.Foo.Name' cannot be used in this context because the set accessor is inaccessible*/ using (DataContext dc = new DataContext(Connection)) { // yet the following line works. **How**? IEnumerable<Foo> qux = dc.ExecuteQuery<Foo>( "SELECT Name FROM Customer"); } foreach (q in qux) Console.WriteLine(q); } I have just been using the private modifier because it works and kept me from being stupid with my code, but now that I need to create a new Foo, I've just removed the private modifier from my property. I'm just really curious, why does the ExecuteQuery into an IEnumerable of Foo's work?

  • Interacting With Class Objects in Ruby

    - by michaelmichael
    How can I interact with objects I've created based on their given attributes in Ruby? To give some context, I'm parsing a text file that might have several hundred entries like the following: ASIN: B00137RNIQ -------------------------Status Info------------------------- Upload created: 2010-04-09 09:33:45 Upload state: Imported Upload state id: 3 I can parse the above with regular expressions and use the data to create new objects in a "Product" class: class Product attr_reader :asin, :creation_date, :upload_state, :upload_state_id def initialize(asin, creation_date, upload_state, upload_state_id) @asin = asin @creation_date = creation_date @upload_state = upload_state @upload_state_id = upload_state_id end end After parsing, the raw text from above will be stored in an object that look like this: [#<Product:0x00000101006ef8 @asin="B00137RNIQ", @creation_date="2010-04-09 09:33:45 ", @upload_state="Imported ", @upload_state_id="3">] How can I then interact with the newly created class objects? For example, how might I pull all the creation dates for objects with an upload_state_id of 3? I get the feeling I'm going to have to write class methods, but I'm a bit stuck on where to start.

  • How can I maximally partition a set?

    - by Gregory Higley
    I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

  • Settings designer file complains when protecting configuration for connectionStrings in App.Config i

    - by Joe
    Hi, I am trying to encrypt Configuration Information Using Protected Configuration in Visual Studio 2010. I have the following info speicifed in the App.Config file: <connectionStrings configProtectionProvider="TheProviderName"> <EncryptedData> <CipherData> <CipherValue>VALUE GOES HERE</CipherValue> </CipherData> </EncryptedData> </connectionStrings> <appSettings configProtectionProvider="TheProviderName"> <EncryptedData> <CipherData> <CipherValue>VALUE GOES HERE</CipherValue> </CipherData> </EncryptedData> </appSettings> However, when I then go to the Settings area of the Projects Properties to view the settings in the Designer, I get prompted with the following error "An error occured while reading the App.config file. The file might be corrupted or contain invalid XML." I understand that my changes are causing the error, however, is there anyway I can bypass that the information is not read into at design view? (Of course the best way would be to make the tags be recognized by the designer, is there any way to do this?) I tried adding <connectionStrings configProtectionProvider="TheProviderName" xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> to connectionStrings as well as to the appSettings, but with no luck, the intellisense is bypassed in the config file, but the designer still complains. I would be satisfied if the designer would not complain about this "error", which is not actually an error because Microsoft states here that it should work. ASP.NET 2.0 provides a new feature, called protected configuration, that enables you to encrypt sensitive information in a configuration file. Although primarily designed for ASP.NET, protected configuration can also be used to encrypt configuration file sections in Windows applications. For a detailed description of the new protected configuration capabilities, see Encrypting Configuration Information Using Protected Configuration. And yes, it does work to encrypt it and to decrypt it and use it, it is just very annoying and frustrating that the designer complains about it. Anyone who knows which xsd file that is used (if used) to verify the contents of the App.config file in the design view? Any help appreciated.

  • C# Linq: Can you merge DataContexts?

    - by Andreas Grech
    Say I have one database, and this database has a set of tables that are general to all Clients and some tables that are specific to certain clients. Now what I have in mind is creating a primary DataContext that includes only the tables that are general to all the clients, and then create separate DataContexts that contain only the tables that are specific to the client. Is there a way to kind of "merge" DataContexts so that it becomes one context? So for Client A, I need one DataContext that includes both the general tables and also the tables for that specific client (retrieved from two different DataContexts) ? [Update] What I think I can do is, from the Partial Class of the DataContext instead of letting my DataContext inherit from DataContext I make it inherit from MyDataContext; that way, the tables from MyDataContext and the other DataContext will be available in one DataContext class. What do you think about this approach? Of course with something like this you can only merge two datacontexts at once though...

  • Pros & Cons of using windows Active Setup

    - by Deepak N
    What are the known Pros/Cons of using windows active setup for deployment? Does Microsoft recommend/support using active set up? If your are interested, here is the context: I'm working on outlook 2003 VSTO addin.The installer for this addin creates few registry entries either in HKCU or HKLM depending on "Single User" Or "All User" installation. We are planning not to use "All User" installation since the addins installed for all users does not show up in COM AddIns list in outlook.The alternate approach is to use active set to install for single user.

  • How to manipulate file paths intelligently in .Net 3.0?

    - by Hamish Grubijan
    Scenario: I am maintaining a function which helps with an install - copies files from PathPart1/pending_install/PathPart2/fileName to PathPart1/PathPart2/fileName. It seems that String.Replace() and Path.Combine() do not play well together. The code is below. I added this section: // The behavior of Path.Combine is weird. See: // http://stackoverflow.com/questions/53102/why-does-path-combine-not-properly-concatenate-filenames-that-start-with-path-dir while (strDestFile.StartsWith(@"\")) { strDestFile = strDestFile.Substring(1); // Remove any leading backslashes } Debug.Assert(!Path.IsPathRooted(strDestFile), "This will make the Path.Combine(,) fail)."); in order to take care of a bug (code is sensitive to a constant @"pending_install\" vs @"pending_install" which I did not like and changed (long story, but there was a good opportunity for constant reuse). Now the whole function: //You want to uncompress only the files downloaded. Not every file in the dest directory. private void UncompressFiles() { string strSrcDir = _application.Client.TempDir; ArrayList arrFiles = new ArrayList(); GetAllCompressedFiles(ref arrFiles, strSrcDir); IEnumerator enumer = arrFiles.GetEnumerator(); while (enumer.MoveNext()) { string strDestFile = enumer.Current.ToString().Replace(_application.Client.TempDir, String.Empty); // The behavior of Path.Combine is weird. See: // http://stackoverflow.com/questions/53102/why-does-path-combine-not-properly-concatenate-filenames-that-start-with-path-dir while (strDestFile.StartsWith(@"\")) { strDestFile = strDestFile.Substring(1); // Remove any leading backslashes } Debug.Assert(!Path.IsPathRooted(strDestFile), "This will make the Path.Combine(,) fail)."); strDestFile = Path.Combine(_application.Client.BaseDir, strDestFile); strDestFile = strDestFile.Replace(Path.GetExtension(strDestFile), String.Empty); ZSharpLib.ZipExtractor.ExtractZip(enumer.Current.ToString(), strDestFile); FileUtility.DeleteFile(enumer.Current.ToString()); } } Please do not laugh at the use of ArrayList and the way it is being iterated - it was pioneered by a C++ coder during a .Net 1.1 era. I will change it. What I am interested in: what is a better way of replacing PathPart1/pending_install/PathPart2/fileName with PathPart1/PathPart2/fileName within the current code. Note that _application.Client.TempDir is just _application.Client.BaseDir + @"\pending_install". While there are many ways to improve the code, I am mainly concerned with the part which has to do with String.Replace(...) and Path.Combine(,). I do not want to make changes outside of this function. I wish Path.Combine(,) took an optional bool flag, but it does not. So ... given my constraints, how can I rework this so that it starts to sucks less? Thanks!

  • better understanding of JSF Life cycle

    - by gurupriyan.e
    I need your help to understand this better. This is my case. I have a custom validator for each of my input controls in the form. So when there is any validation error,I add a corresponding FacesMessage in the validate method. My understanding was that when there is any validation error - or when there are any FacesMessages added in the validate method of the Custom Validator, it would skip the INVOKE APPLICATION phase and would directly call the RENDER RESPONSE PHASE - showing the FacesMessage that was added in the PROCESS VALIDATION Phase - Is this correct? The problem I'm facing is - I add a FacesMessage in the PROCESS VALIDATION Phase - because of a validation error - and I add a confirmation message for the action that was taken by the user in the INVOKE APPLICATION PHASE - Now both are shown in the page in the RENDER RESPONSE Phase ? - If my understanding is correct in the above question - is it the best practice to conditionally add a confirmation FacesMessage after confirming that there are no FacesMessages in the currect FacesContext ? Appreciate your help.

  • Is everyone baking the same CI cake?

    - by Brett Rigby
    I can't help but wonder about this whole Continous Integration process and wanted to know what you think about it all. From my perspective, we're constructing our own 'flavour' of NAnt/Ivy/CruiseControl.Net in-house and can't help but get the feeling that other dev shops are doing exactly the same work, but then everybody is finding out the same problems and pitfalls with it. I'm not complaining about NAnt, Ivy or CruiseControl at all, as they've been brilliant in helping our team of developers become more sure of the quality of their code, but it just seems strange that these tools are very popular, yet we're all re-inventing the CI-wheel. Is there a pre-made solution for building .Net applications, using the tools mentioned above, and if so, why aren't we all using them??

  • Composite Primary and Cardinality

    - by srini.venigalla
    I have some questions on Composite Primary Keys and the cardinality of the columns. I searched the web, but did not find any definitive answer, so I am trying again. The questions are: Context: Large (50M - 500M rows) OLAP Prep tables, not NOSQL, not Columnar. MySQL and DB2 1) Does the order of keys in a PK matter? 2) If the cardinality of the columns varies heavily, which should be used first. For example, if I have CLIENT/CAMPAIGN/PROGRAM where CLIENT is highly cardinal, CAMPAIGN is moderate, PROGRAM is almost like a bitmap index, what order is the best? 3) What order is the best for Join, if there is a Where clause and when there is no Where Clause (for views) Thanks in advance.

  • unrecognized selector sent to instance

    My app works fine in the simulator but when I run it on my phone I get this error: 2010-04-05 21:32:45.119 Top Banana[119:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[MethodViewController setReferringObject:]: unrecognized selector sent to instance 0x16e930' It happens here: -(void)method { [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.50]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO]; MethodViewController *methodViewController = [[MethodViewController alloc] initWithNibName:@"MethodViewController" bundle:0]; NSManagedObject *selectedObject = self.referringObject; methodViewController.referringObject = selectedObject; [self.navigationController pushViewController:methodViewController animated:NO]; methodViewController.title = @"Method"; [UIView commitAnimations]; [MethodViewController release]; } It crashes on this line: methodViewController.referringObject = selectedObject; Not sure how to resolve this as it works in the simulator, I'm sure it is fairly basic to fix, any help will be appreciated.

  • How do I enable code coverage in Visual Studio 2005?

    - by CandlesOfThe
    I have looked at this question; http://stackoverflow.com/questions/2872158/ and the F1 page, but that doesn't help me much. I have set the profiling on and rebuilt, but I can't find the 'Data and Diagnostics' page, or see anything which resembles a coverage data file in the project folder. What I am trying to do get an equivalent to 'gcov' on a Linux platform, get a chart of how much code is being missed by the test suite. I'm using Visual Studio 2005 Professional Edition and UnitTest++ as the test framework. Any help would be most welcome.

  • In Entity framework, we can use Model first, DB first, Code first but how can we create table programmatically

    - by AukI
    In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ). What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3. To be more specific , from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do?

  • Using control from a separate class in C#

    - by DazSlayer
    I have a program that dynamically creates controls when it starts, it works just fine when the code to do this is in the class of the actual form. I tried moving the code to a separate class and found that I could not use Controls.Add(). How can I add controls to the Form from a separate class? This is what I have so far: TextBox txtbx = new TextBox(); txtbx.Text = "asd" + x.ToString(); txtbx.Name = "txtbx" + x.ToString(); txtbx.Location = new Point(10, (20 * x)); txtbx.Height = 20; txtbx.Width = 50; Controls.Add(txtbx); Error 1 The name 'Controls' does not exist in the current context

  • Why would MessageBox fail silently?

    - by Tim Gradwell
    Does anyone know how MessageBox(...) could fail silently? MessageBox(g_hMainhWnd, buffer, "Oops!", MB_OK | MB_ICONERROR); ShellExecute(0, "open", "http://intranet/crash_handler.php", NULL, "", SW_SHOWNORMAL); For a little context, this code is called inside our own exception handler, which was registered with SetUnhandledExceptionFilter() Most of the time, I see the message box, and then it launches a web browser. However, I have an exe, which as far as I'm aware uses this exact code, and it successfully launches the web browser, but I do not see the message box first. Thanks Tim

    HI there I am hoping for some help with a query I have. I have this query var group = from r in CustomerItem group r by r.StoreItemID into g select new { StoreItemID = g.Key, ItemCount = g.Count(), ItemAmount = Customer.Sum(cr => cr.ItemAmount),RedeemedAmount = Customer.Sum(x => x.RedeemedAmount) }; I am returning my results to a list so I can bind it listbox. I have a property called EntryType which is an int. There are 2 available numbers 1 or 2 Lets say I had 3 items that my query is working with 2 of them had the EntryType = 1 and the 3rd had EntryType2. The first records had a ItemAmount of 55.00 and the 3rd had a ItemAmount of 50.00 How can I group using something simlar to above but minus the ItemAmount of 50.00 from the grouped amount to return 60.00? Any help would be great!!
