• Need to kill a session?

  - by rob - not a robber

  Really quick here... I think I have the answer, but just looking for some validation. I have a site with two "points of entry." One is for a standard user and one is for an admin account. In the real world, an admin could have a standard user account and try to login as an admin while already being under the standard user session. I have two separate front ends to facilitate login. The normal user one is frilly and has ads and the like, the admin one is strictly business, so any suggestion to have the two user types login through the same "door" is not on the table. Would you advise on the admin login page to destroy any active sessions? Once the admin is in, they'll only be tooling around in their admin area and not on the main site. Has anyone run into probs using this method and having an admin-type user try to log back in in a new window as a "user" to view changes from a logged in user's prespective? Thanks in advance. So many cans of worms :)

• Put message after long idle time does not work

  - by Sydney

  I wrote a simple Java client using MQ v7 libraries (No JMS). I try to put a message in a queue using the following pattern: Put a message Wait for x minutes Put a message again It works but if the idle time is too long (between 5-7 minutes), I get the following error: MQJE001: An MQException occurred: Completion Code 2, Reason 2195 MQJE007: IO error reading message data Error occured during API call - reason code0 MQJE001: Completion Code 2, Reason 2009 MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE003: IO error transmitting message buffer MQJE001: Completion Code 2, Reason 2009 MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE003: IO error transmitting message buffer MQJE001: Completion Code 2, Reason 2009 MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE003: IO error transmitting message buffer MQJE001: Completion Code 2, Reason 2009 MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE003: IO error transmitting message buffer MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE003: IO error transmitting message buffer MQJE001: Completion Code 2, Reason 2009 An MQSeries error occurred : Completion code 2 Reason code 2009 com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2009 at com.ibm.mq.MQQueue.put(MQQueue.java:1511) After reading several threads on the subject, this error is usually creating FDC dumps but I have nothing in the system and queue manager logs. The channel is a SVRCONN channel.

• Find first item inside angular brackets after occurrence of other item, using RegEx, in C#

  - by Mihaela

  I have an xml-like text, in which I would like to find the item that occurs in the first occurrence of a certain pattern: typically: ... <PropertyGroup><name>true</name></PropertyGroup><PropertyGroup>.... .... Could also be ... <PropertyGroup> <name> true</name> </PropertyGroup> ... <PropertyGroup> ... In the above, I need to extract the "name". My initial assumption was that all occurrences were to be in one line, and I wrote my code using string properties, but it is very difficult o take in consideration every possibility, and only RegEx can save me. I just don't know how to write it... I Have started with something like this: Regex regex = new Regex("(?<=<PropertyGroup>#)<+"); Match matches = regex.Matches(Text)[0]; MessageBox.Show(matches.ToString()); I think this finds the first item after a <PropertyGroup>, but I don't know how to make it get the item within the angular brackets... (which may be after one or more newlines, and/or spaces). I know that there are utilities for parsing xml, but I am looking for something simple to insert in a c# program Can someone please help me ? Thank you very much.

• How to tell what name RIA Services/EF Model uses for Associations?

  - by Nick Gotch

  Hi, I'm working on a C#.NET 3.5 WCF RIA Services app and having an issue with my Entity Framework model. My entity Foo is mapped to a DB table and has a primary key called FooId. My Bar is mapped to a DB view. I've selectively designed this view to generate a composite key in the EF using two of the columns (by making sure they were non-nullable and the others are all nullable. This was done using NULLIF and ISNULL in the view design.) I'm able to add this view to the model with no problem but I keep running into an issue when I try to map an association between the two. Foo should contain many Bars but I keep getting the following error when I add the association: Unable to retrieve AssociationType for association 'FK_Bar_Foo' According to this page, it looks like this might work if I can properly name the association (since RIA Services looks for specific names.) I've tried several variants of names that match the pattern of other associations with no success. Does anyone know if there's a place I can look to find out what name it's looking for? Thanks,

• Accessing a file on a network drive

  - by Rekreativc

  Hello. Background: I have an application that has to read from files on a network drive (Z:) This works great in my office domain, however it does not work on site (in a different domain). As far as I can tell the domain users and network drives are set in the same way, however I do not have access to users etc in the customers domain. When I couldn't access the network drive I figured I needed a token for a user. This is how I impersionate the user: [DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); ... const string userName = "Razvoj02"; const string pass = "Programer02"; const string domainName = null; const int LOGON32_PROVIDER_DEFAULT = 0; const int LOGON32_LOGON_INTERACTIVE = 2; IntPtr tokenHandle = new IntPtr(0); bool returnValue = LogonUser(userName, domainName, pass, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref tokenHandle); if (!returnValue) throw new Exception("Logon failed."); WindowsImpersonationContext impersonatedUser = null; try { WindowsIdentity wid = new WindowsIdentity(tokenHandle); impersonatedUser = wid.Impersonate(); } finally { if (impersonatedUser != null) impersonatedUser.Undo(); } Now here is the interesting/weird part. In my network the application can already access the network drive, and if I try to impersonate the active user (exactly the same user, including the same domain) it will not be able to access the network drive. This leaves me helpless since now I have no idea what works and what doesn't, and more to the point, will it work on site? What am I missing?

• NSKeyedArchiver on NSArray has large size overhead

  - by redguy

  I'm using NSKeyedArchiver in Mac OS X program which generates data for iPhone application. I found out that by default, resulting archives are much bigger than I expected. Example: NSMutableArray * ar = [NSMutableArray arrayWithCapacity:10]; for (int i = 0; i < 100000; i++) { NSString * s = [NSString stringWithFormat:@"item%06d", i]; [ar addObject:s]; } [NSKeyedArchiver archiveRootObject:ar toFile: @"NSKeyedArchiver.test"]; This stores 10 * 100000 = 1M bytes of useful data, yet the size of the resulting file is almost three megabytes. The overhead seems to be growing with number of items in the array. In this case, for 1000 items, the file was about 22k. "file" reports that it is a "Apple binary property list" (not the XML format). Is there an simple way to prevent this huge overhead? I wanted to use the NSKeyedArchiver for the simplicity it provides. I can write data to my own, non-generic, binary format, but that's not very elegant. Also, aggregating the data into large chunks and feeding these to the NSKeyedArchiver should work, but again, that kinda beats the point of using simple&easy&ready to use archiver. Am I missing some method call or usage pattern that would reduce this overhead?

• ASP.NET: aggregating validators in a user control

  - by orsogufo

  I am developing a web application where I would like to perform a set of validations on a certain field (an account name in the specific case). I need to check that the value is not empty, matches a certain pattern and is not already used. I tried to create a UserControl that aggregates a RequiredFieldValidator, a RegexValidator and a CustomValidator, then I created a ControlToValidate property like this: public partial class AccountNameValidator : System.Web.UI.UserControl { public string ControlToValidate { get { return ViewState["ControlToValidate"] as string; } set { ViewState["ControlToValidate"] = value; AccountNameRequiredFieldValidator.ControlToValidate = value; AccountNameRegexValidator.ControlToValidate = value; AccountNameUniqueValidator.ControlToValidate = value; } } } However, if I insert the control on a page and set ControlToValidate to some control ID, when the page loads I get an error that says Unable to find control id 'AccountName' referenced by the 'ControlToValidate' property of 'AccountNameRequiredFieldValidator', which makes me think that the controls inside my UserControl cannot resolve correctly the controls in the parent page. So, I have two questions: 1) Is it possible to have validator controls inside a UserControl validate a control in the parent page? 2) Is it correct and good practice to "aggregate" multiple validator controls in a UserControl? If not, what is the standard way to proceed?

• Mercurial 1.5 pager on Windows

  - by alexandrul

  I'm trying to set the pager used for Mercurial but the output is empty, even if I specify the command in the [pager] section or as the PAGER environment variable. I noticed that the command provided is launched with cmd.exe. Is this the cause of empty output, and if yes, what is the right syntax? Environment: Mercurial 1.5, Mecurial 1.4.3 hgrc: [extensions] pager = [pager] pager = d:\tools\less\less.exe Sample command lines (from Process Explorer): hg diff c:\windows\system32\cmd.exe /c "d:\tools\less\less.exe 2> NUL:" d:\tools\less\less.exe UPDATE In pager.py, by replacing: sys.stderr = sys.stdout = util.popen(p, "wb") with sys.stderr = sys.stdout = subprocess.Popen(p, stdin = subprocess.PIPE, shell=False).stdin I managed to obtain the desired output for the hg status and diff. BUT, I'm sure it's wrong (or at least incomplete), and I have no control over the pager app (less.exe): the output is shown in the cmd.exe window, I can see the less prompt (:) but any further input is fed into cmd.exe. It seems that the pager app is still active in the background: after typing exit in the cmd.exe window, I have control over the pager app, and I can terminate it normally. Also, it makes no difference what I'm choosing as a pager app (more is behaving the same). UPDATE 2 Issue1677 - [PATCH] pager for "hg help" output on windows

• Autodetect Presence of CSV Headers in a File

  - by banzaimonkey

  Short question: How do I automatically detect whether a CSV file has headers in the first row? Details: I've written a small CSV parsing engine that places the data into an object that I can access as (approximately) an in-memory database. The original code was written to parse third-party CSV with a predictable format, but I'd like to be able to use this code more generally. I'm trying to figure out a reliable way to automatically detect the presence of CSV headers, so the script can decide whether to use the first row of the CSV file as keys / column names or start parsing data immediately. Since all I need is a boolean test, I could easily specify an argument after inspecting the CSV file myself, but I'd rather not have to (go go automation). I imagine I'd have to parse the first 3 to ? rows of the CSV file and look for a pattern of some sort to compare against the headers. I'm having nightmares of three particularly bad cases in which: The headers include numeric data for some reason The first few rows (or large portions of the CSV) are null There headers and data look too similar to tell them apart If I can get a "best guess" and have the parser fail with an error or spit out a warning if it can't decide, that's OK. If this is something that's going to be tremendously expensive in terms of time or computation (and take more time than it's supposed to save me) I'll happily scrap the idea and go back to working on "important things". I'm working with PHP, but this strikes me as more of an algorithmic / computational question than something that's implementation-specific. If there's a simple algorithm I can use, great. If you can point me to some relevant theory / discussion, that'd be great, too. If there's a giant library that does natural language processing or 300 different kinds of parsing, I'm not interested.

• Strip parity bits in C from 8 bits of data followed by 1 parity bit

  - by dubnde

  I have a buffer of bits with 8 bits of data followed by 1 parity bit. This pattern repeats itself. The buffer is currently stored as an array of octets. Example (p are parity bits): 0001 0001 p000 0100 0p00 0001 00p01 1100 ... should become 0001 0001 0000 1000 0000 0100 0111 00 ... Basically, I need to strip of every ninth bit to just obtain the data bits. How can I achieve this? This is related to another question asked here sometime back. This is on a 32 bit machine so the solution to the related question may not be applicable. The maximum possible number of bits is 45 i.e. 5 data octets This is what I have tried so far. I have created a "boolean" array and added the bits into the array based on the the bitset of the octet. I then look at every ninth index of the array and through it away. Then move the remaining array down one index. Then I've got only the data bits left. I was thinking there may be better ways of doing this.

• Finding string in php

  - by Roshan

  I have a content and i want to search a keyword in that content. Content When charting multiple data series, or just to improve the appearance of your charts, you can control the fill for each series in the chart or each item in a series. The fill lets you specify a pattern that defines how Flex draws the chart element. You also use fills to specify the background colors of the chart or bands of background colors defined by the grid lines. Fills can be solid or can use linear and radial gradients. A gradient specifies a gradual color transition in the fill color therefore. NOw, if the keyword we are searching is "When", it is the starting word so should display as "When charting multiple data ..........." If the keyword is "draws" , it lies in middle so should be displayed as ".... how Flex draws....." If the kewyword is "therefore", it is in the last position so should be displayed as ".........transition in the fill color therefore." Can anyone help me out how to do this in php server script?

• Publish Maven artifacts on FTP with Hudson FTP Publisher Plugin

  I'm building a number of artefacts (zip files for different environments: test, dev) using the maven-assembly-plugin using a specialized Maven profile. These artefacts I want to copy/collect on on a FTP server keeping the version (01.07.10.16.Wed-1626) as a folder, so I need to copy from test/build/01.07.10.16.Wed-1626/ to ftp://my-ftp-server:21/projects/myserver-1.7/01.07.10.16.Wed-1626/ The layout for the Maven output is this: target/ build/ 01.07.10.16.Wed-1626/ my-server-01.07.10.16.Wed-1626-dev.zip my-server-01.07.10.16.Wed-1626-test.zip For copying the artefacts I'm using FTP Publisher Plugin but it seams I miss something since that even the build is OK and the artefacts are build without problem but the job is finishing without copying the artefacts, and in the console there is no log info about copying the artefacts My FTP publisher config (FTP repository hosts) is: Hostname: my-ftp-server Port: 21 Timeout: 10000 Root Repository Path: projects User Name: my-user Password: my-pass My Hudson job FTP publisher config (Publish artifacts to FTP) is: FTP site: my-ftp-server Files to upload Source: target/build/** Destination: myserver-1.7 1: There is any log to check if there are any FTP copy errors ? 2: There is any problem with the file pattern (source) or with the dest ?

• In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

  - by Navi

  I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

• SQL Server CLR stored procedures in data processing tasks - good or evil?

  - by Gart

  In short - is it a good design solution to implement most of the business logic in CLR stored procedures? I have read much about them recently but I can't figure out when they should be used, what are the best practices, are they good enough or not. For example, my business application needs to parse a large fixed-length text file, extract some numbers from each line in the file, according to these numbers apply some complex business rules (involving regex matching, pattern matching against data from many tables in the database and such), and as a result of this calculation update records in the database. There is also a GUI for the user to select the file, view the results, etc. This application seems to be a good candidate to implement the classic 3-tier architecture: the Data Layer, the Logic Layer, and the GUI layer. The Data Layer would access the database The Logic Layer would run as a WCF service and implement the business rules, interacting with the Data Layer The GUI Layer would be a means of communication between the Logic Layer and the User. Now, thinking of this design, I can see that most of the business rules may be implemented in a SQL CLR and stored in SQL Server. I might store all my raw data in the database, run the processing there, and get the results. I see some advantages and disadvantages of this solution: Pros: The business logic runs close to the data, meaning less network traffic. Process all data at once, possibly utilizing parallelizm and optimal execution plan. Cons: Scattering of the business logic: some part is here, some part is there. Questionable design solution, may encounter unknown problems. Difficult to implement a progress indicator for the processing task. I would like to hear all your opinions about SQL CLR. Does anybody use it in production? Are there any problems with such design? Is it a good thing?

• Asynchronous background processes in Python?

  - by Geuis

  I have been using this as a reference, but not able to accomplish exactly what I need: http://stackoverflow.com/questions/89228/how-to-call-external-command-in-python/92395#92395 I also was reading this: http://www.python.org/dev/peps/pep-3145/ For our project, we have 5 svn checkouts that need to update before we can deploy our application. In my dev environment, where speedy deployments are a bit more important for productivity than a production deployment, I have been working on speeding up the process. I have a bash script that has been working decently but has some limitations. I fire up multiple 'svn updates' with the following bash command: (svn update /repo1) & (svn update /repo2) & (svn update /repo3) & These all run in parallel and it works pretty well. I also use this pattern in the rest of the build script for firing off each ant build, then moving the wars to Tomcat. However, I have no control over stopping deployment if one of the updates or a build fails. I'm re-writing my bash script with Python so I have more control over branches and the deployment process. I am using subprocess.call() to fire off the 'svn update /repo' commands, but each one is acting sequentially. I try '(svn update /repo) &' and those all fire off, but the result code returns immediately. So I have no way to determine if a particular command fails or not in the asynchronous mode. import subprocess subprocess.call( 'svn update /repo1', shell=True ) subprocess.call( 'svn update /repo2', shell=True ) subprocess.call( 'svn update /repo3', shell=True ) I'd love to find a way to have Python fire off each Unix command, and if any of the calls fails at any time the entire script stops.

• BackgroundWorker From ASP.Net Application

  - by Kevin

  We have an ASP.Net application that provides administrators to work with and perform operations on large sets of records. For example, we have a "Polish Data" task that an administrator can perform to clean up data for a record (e.g. reformat phone numbers, social security numbers, etc.) When performed on a small number of records, the task completes relatively quickly. However, when a user performs the task on a larger set of records, the task may take several minutes or longer to complete. So, we want to implement these kinds of tasks using some kind of asynchronous pattern. For example, we want to be able to launch the task, and then use AJAX polling to provide a progress bar and status information. I have been looking into using the BackgroundWorker class, but I have read some things online that make me pause. I would love to get some additional advice on this. For example, I understand that the BackgroundWorker will actually use the thread pool from the current application. In my case, the application is an ASP.Net web site. I have read that this can be a problem because when the application recycles, the background workers will be terminated. Some of the jobs I mentioned above may take 3 minutes, but others may take a few hours. Also, we may have several hundred administrators all performing similar operations during the day. Will the ASP.Net application thread pool be able to handle all of these background jobs efficiently while still performing it's normal request processing? So, I am trying to determine if using the BackgroundWorker class and approach is right for our needs. Should I be looking at an alternative approach? Thanks and sorry for such a long post! Kevin

• Frameworks to manage dates (effective date and expiry dates)

  - by user214626

  Hello, We have an object that can has an effective date and expiry date.(Ex. i want to maintain the price of a commodity for a time period) Business Rules - Effective date is always a valid date (a datestamp) but, expiry date can be null to indicate that the object is active throughout. Also, both effective and expiry date can be set to some valid dates. Are there any frameworks that manage objects such that the objects are consistent,i.e there are no overlaps of the validity periods ? Ex. class XBOX { double price; Date effectiveDate; Date expiryDate; } XBOX x1 = new XBOX(400$, '2007-01-01','2008-12-31' ); XBOX x2 = new XBOX(200$, '2009-01-01',null ); Assume that we get a new rate from '2010-01-01' and a new XBOX object has to be created (to persist). Is there a framework/pattern that can do the following, so that the XBOX is consistent. x2.setExpiryDate('2009-12-31') XBOX x3 = new XBOX(150$, '2010-01-01',null ); Thanks in advance.

• Spelling correction for data normalization in Java

  - by dareios

  I am looking for a Java library to do some initial spell checking / data normalization on user generated text content, imagine the interests entered in a Facebook profile. This text will be tokenized at some point (before or after spell correction, whatever works better) and some of it used as keys to search for (exact match). It would be nice to cut down misspellings and the like to produce more matches. It would be even better if the correction would perform well on tokens longer than just one word, e.g. "trinking coffee" would become "drinking coffee" and not "thinking coffee". I found the following Java libraries for doing spelling correction: JAZZY does not seem to be under active development. Also, the dictionary-distance based approach seems inadequate because of the use of non-standard language in social network profiles and multi-word tokens. APACHE LUCENE seems to have a statistical spell checker that should be much more suited. Question here would how to create a good dictionary? (We are not using Lucene otherwise, so there is no existing index.) Any suggestions are welcome!

• Detecting Xml namespace fast

  - by Anna Tjsoken

  Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

• Set the caret/cursor position to the end of the string value WPF textbox

  - by Zamboni

  I am try to set the caret/cursor position to the end of the string value in my WPF textbox when I open my window for the first time. I use the FocusManager to set the focus on my textbox when my window opens. Nothing seems to work. Any ideas? Note, I am using the MVVM pattern, and I included only a portion of the XAML from my code. <Window FocusManager.FocusedElement="{Binding ElementName=NumberOfDigits}" Height="400" Width="800"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBox Grid.Column="0" Grid.Row="0" x:Name="NumberOfDigits" IsReadOnly="{Binding Path=IsRunning, Mode=TwoWay}" VerticalContentAlignment="Center" Text="{Binding Path=Digits, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/> <Button Grid.Column="0" Grid.Row="1" Margin="10,0,10,0" IsDefault="True" Content="Start" Command="{Binding StartCommand}"/> </Grid> </Window>

• Add Zend_Navigation to the View with old legacy bootstrap

  - by Grant Collins

  Hi, I've been struggling with Zend_Navigation all weekend, and now I have another problem, which I believe has been the cause of a lot of my issues. I am trying to add Zend_Navigation to a legacy 1.7.6 Zend Framework application, i've updated the Zend Library to 1.9.0 and updated the bootstrap to allow this library update. The problem is that I don't know how, and the examples show the new bootstrap method of how to add the Navigation object to the view, I've tried this: //initialise the application layouts with the MVC helpers $layout = Zend_Layout::startMvc(array('layoutPath' => '../application/layouts')); $view = $layout->getView(); $configNav = new Zend_Config_Xml('../application/config/navigation.xml', 'navigation'); $navigation = new Zend_Navigation($configNav); $view->navigation($navigation); $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); This seems to run through fine, but when I go to use the breadcrumb view helper in my layout, it errors with: Strict Standards: Creating default object from empty value in C:\www\moobia\development\website\application\modules\employers\controllers\IndexController.php on line 27 This is caused by the following code in the init() function of my controller. $uri = $this->_request->getPathInfo(); $activeNav = $this->view->navigation()->findByUri($uri); <- this is null when called $activeNav->active = true; I believe it's because the Zend_Navigation object is not in the view. I would look at migrating the bootstrap to the current method, but at present I am running out of time for a release. Thanks, Grant

• "Illegal characters in path." Visual Studio WinForm Design View

  - by jacksonakj

  I am putting together a lightweight MVP pattern for a WinForms project. Everything compiles and runs fine. However when I attempt to open the WinForm in design mode in Visual Studio I get a "Illegal characters in path" error. My WinForm is using generics and inheriting from a base Form class. Is there a problem with using generics in a WinForm? Here is the WinForm and base Form class. public partial class TapsForm : MvpForm<TapsPresenter, TapsFormModel>, ITapsView { public TapsForm() { InitializeComponent(); } public TapsForm(TapsPresenter presenter) :base(presenter) { InitializeComponent(); UpdateModel(); } public IList<Taps> Taps { set { gridTaps.DataSource = value; } } private void UpdateModel() { Model.RideId = Int32.Parse(cboRide.Text); Model.Latitude = Double.Parse(txtLatitude.Text); Model.Longitude = Double.Parse(txtLongitude.Text); } } Base form MvpForm: public class MvpForm<TPresenter, TModel> : Form, IView where TPresenter : class, IPresenter where TModel : class, new() { private readonly TPresenter presenter; private TModel model; public MvpForm() { } public MvpForm(TPresenter presenter) { this.presenter = presenter; this.presenter.RegisterView(this); } protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (presenter != null) presenter.IntializeView(); } public TModel Model { get { if (model == null) throw new InvalidOperationException("The Model property is currently null, however it should have been automatically initialized by the presenter. This most likely indicates that no presenter was bound to the control. Check your presenter bindings."); return model; } set { model = value;} } }
