• Using git submodules in a git-svn project

  - by Matthias

  In our git-svn managed project, we have 3 upstream projects that are all kept in native git repositories on GitHub. Since the source code of those upstream projects is under our control and changes frequently, our current solution, namely re-deploying the build artifacts to the super-project everytime we change something is quite cumbersome. What I'd like to have is this: parent project (git-svn): --> submodule 1 (git) --> submodule 2 (git) --> submodule 3 (git) That way, the source code for submodules 1-3 is compiled along with the sources for the super project, but I can push changes to submodules separately. The question is: what happens when I git svn dcommit on the parent project? Does this even work? UPDATE Hm, I just set up a simple project structure, trying to resemble this scenario, and I receive this error message when trying to dcommit on the superproject: a0301b11f3544a1e71067ff270eded65e4c8afbd doesn't exist in the repository at /opt/local/libexec/git-core/git-svn line 4775 Failed to read object a0301b11f3544a1e71067ff270eded65e4c8afbd at /opt/local/libexec/git-core/git-svn line 574 Any ideas/suggestions?

• Log4net Logging Problem : Very simple file appender logging not working

  - by contactmatt

  Here's my web.config information <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <root> <level value="ALL" /> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\log-file.txt" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> </log4net> ... Here's the code that initalizes the logger protected void SendMessage() { log4net.Config.XmlConfigurator.Configure(); ILog log = LogManager.GetLogger(typeof(Contact)); ... log.Info("here we go!"); log.Debug("debug afasf"); ... } it doesn't work, no matter what I seem to do. I am referencing the 'log4net.dll' correctly, and by debugging the application i can see that the log object is getting initiated properly. This is a asp.net 3.5 framework web project. Any ideas/suggestions? I thought originally this error may be due to a file write permission constraint, but that doesn't seem to be the case (or so I think).

• VB.Net Validate an xml against a schema (strange problem)

  - by Apeksha

  I have written a small XML validator, that takes in an XML file and an XML schema and validates the XML files against that schema. It works well, except for an XML file, with this content: <?xml version="1.0" encoding="utf-8"?> <xc:program xmlns:xc="http:\\www.something.com\Schema\XC10" xc:version="4.0.22.0" > <xc:namespaceDecls> <xc:namespaceDecl xc:namespaceDeclURI="urn:swift:xsd:abc"> <xc:namespaceDeclPrefix>n</xc:namespaceDeclPrefix> </xc:namespaceDecl> </xc:namespaceDecls> </xc:program> I tried to validate this XML file against a bunch of different schemas. No matter which schema I select, this XML file comes out as valid. What is it that I am missing? Here is the relevant piece of code: 'Create a schema cache and add the given schema to it. Dim schemaCache As New Schema.XmlSchemaSet schemaCache.Add(targetNamespace, schemaFilename) 'Create an XML DOMDocument object. Dim xmlDom As New XmlDocument 'Assign the schema cache to the DOM document. 'schemas collection. xmlDom.Schemas = schemaCache 'Load selected file as the DOM document. xmlDom.Load(xmlFilename) xmlDom.Validate(AddressOf ValidationCallBack)

• WPF - How to properly reference a class from XAML

  - by Andy T

  OK, this is a super super noob question, one that I'm almost embarrassed to ask... I want to reference a class in my XAML file. It's a DataTemplateSelector for selecting the right edit template for a DataGrid column. Anyway, I've written the class into my code behind, added the local namespace to the top of top of the XAML, but when I try to reference the class from the XAML, it tells me the class does not exist in the local namespace. I must be missing something really really simple but I just can't understand it... Here's my code. XAML: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:local="clr-namespace:CustomFields" xmlns:col="clr-namespace:System.Collections;assembly=mscorlib" xmlns:sys="clr-namespace:System;assembly=mscorlib" x:Class="CustomFields.MainWindow" x:Name="Window" Title="Define Custom Fields" Width="425" Height="400" MinWidth="425" MinHeight="400"> <Window.Resources> <ResourceDictionary> <local:RangeValuesEditTemplateSelector> blah blah blah... </local:RangeValuesEditTemplateSelector> </ResourceDictionary> </Window.Resources> C#: namespace CustomFields { /// /// Interaction logic for MainWindow.xaml /// public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); // Insert code required on object creation below this point. } } public class RangeValuesEditTemplateSelector : DataTemplateSelector { public RangeValuesEditTemplateSelector(){ MessageBox.Show("hello"); } } } Any ideas what I'm doing wrong? I thought this should be simple as 1-2-3... Thanks! AT

• Custom Java ListCellRenderer - Can't click JCheckBox

  - by Spencer

  Made a custom ListCellRenderer: import java.awt.Component; import javax.swing.JCheckBox; import javax.swing.JLabel; import javax.swing.JList; import javax.swing.JPanel; import javax.swing.ListCellRenderer; /** * * @author Spencer */ public class TaskRenderer implements ListCellRenderer { private Task task; private JPanel panel = new JPanel(); private JCheckBox checkbox = new JCheckBox(); private JLabel label = new JLabel(); public TaskRenderer() { panel.add(checkbox); panel.add(label); } public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { task = (Task) value; label.setText(task.getName()); return panel; } } Have a JList with each cell in it rendered using the above class, but the checkboxes in the panels for each cell cannot be clicked. Thought it had to do with it not getting focus. Any ideas? Thanks, Spencer

• Is there a more easy way to create a WCF/OData Data Service Query Provider?

  - by routeNpingme

  I have a simple little data model resembling the following: InventoryContext { IEnumerable<Computer> GetComputers() IEnumerable<Printer> GetPrinters() } Computer { public string ComputerName { get; set; } public string Location { get; set; } } Printer { public string PrinterName { get; set; } public string Location { get; set; } } The results come from a non-SQL source, so this data does not come from Entity Framework connected up to a database. Now I want to expose the data through a WCF OData service. The only way I've found to do that thus far is creating my own Data Service Query Provider, per this blog tutorial: http://blogs.msdn.com/alexj/archive/2010/01/04/creating-a-data-service-provider-part-1-intro.aspx ... which is great, but seems like a pretty involved undertaking. The code for the provider would be 4 times longer than my whole data model to generate all of the resource sets and property definitions. Is there something like a generic provider in between Entity Framework and writing your own data source from zero? Maybe some way to build an object data source or something, so that the magical WCF unicorns can pick up my data and ride off into the sunset without having to explicitly code the provider?

• get column names from a table where one of the column name is a key word.

  - by syedsaleemss

  Im using c# .net windows form application. I have created a database which has many tables. In one of the tables I have entered data. In this table I have 4 columns named key, name,age,value. Here the name "key" of the first column is a key word. Now I am trying to get these column names into a combo box. I am unable to get the name "key". It works for "key" when I use this code: private void comboseccolumn_SelectedIndexChanged(object sender, EventArgs e) { string dbname = combodatabase.SelectedItem.ToString(); string path = @"Data Source=" + textBox1.Text + ";Initial Catalog=" + dbname + ";Integrated Security=SSPI"; //string path=@"Data Source=SYED-PC\SQLEXPRESS;Initial Catalog=resources;Integrated Security=SSPI"; SqlConnection con = new SqlConnection(path); string tablename = comboBox2.SelectedItem.ToString(); //string query= "Select * from" +tablename+; //SqlDataAdapter adp = new SqlDataAdapter(" Select [Key] ,value from " + tablename, con); SqlDataAdapter adp = new SqlDataAdapter(" Select [" + combofirstcolumn.SelectedItem.ToString() + "]," + comboseccolumn.SelectedItem.ToString() + "\t from " + tablename, con); DataTable dt = new DataTable(); adp.Fill(dt); dataGridView1.DataSource = dt; } This is beacuse I am using "[" in the select query. But it wont work for non keys. Or if I remove the "[" it is not working for key . Please suggest me so that I can get both key as well as nonkey column names.

• Append a dynamically changing watermark to a PDF in SharePoint

  - by ccomet

  This is primarily a question of possibilities more than instructions. I'm a programming consultant working on a WSS project site system for my client. We have a document library in which files are uploaded to go through a complex approval process. With multiple stages in this process, we have an extra field which dictates what the current status of the document is. Now, my client has become enamored with the idea of PDF watermarking. He wants the document (which is already a PDF) to be affixed with a watermark corresponding to the current status, such that with each stage of the approval process the watermark will change. One method, the traditional method for PDF watermarking, of accomplishing this is to have one "clean" copy of the document somewhere hidden on the site, and create a new PDF from it that has the watermark at each stage of the approval process. Since the filename will never change, this new PDF can be uploaded continually to a public library, always overwriting the old version and simulating a "dynamically changing watermark". However, in the various stages there will also be people uploading clean copies with corrections and suggestions, nevermind the complex nature of juggling around two libraries and the fact we double the number of files stored. My client and I agree that this is not a practical path to choose. What we would like to do is be able to "modify" the watermark in a PDF, so that we only have to keep one copy of the file. Unfortunately, from what I've seen, in most cases when you make something like a watermark, which in its nature is supposed to be "unmodifyable", you won't be able to edit it later. So, is it possible to have a part of a PDF which cannot be changed by anyone who downloads the file, but can be changed as part of a workflow or other object model process? Thanks in advance!

• Data Contract Serialization Not Working For All Elements

  - by splatto

  I have an XML file that I'm trying to serialize into an object. Some elements are being ignored. My XML File: <?xml version="1.0" encoding="utf-8" ?> <License xmlns="http://schemas.datacontract.org/2004/07/MyApp.Domain"> <Guid>7FF07F74-CD5F-4369-8FC7-9BF50274A8E8</Guid> <Url>http://www.gmail.com</Url> <ValidKey>true</ValidKey> <CurrentDate>3/1/2010 9:39:28 PM</CurrentDate> <RegistrationDate>3/8/2010 9:39:28 PM</RegistrationDate> <ExpirationDate>3/8/2099 9:39:28 PM</ExpirationDate> </License> My class definition: [DataContract] public class License { [DataMember] public virtual int Id { get; set; } [DataMember] public virtual string Guid { get; set; } [DataMember] public virtual string ValidKey { get; set; } [DataMember] public virtual string Url { get; set; } [DataMember] public virtual string CurrentDate { get; set; } [DataMember] public virtual string RegistrationDate { get; set; } [DataMember] public virtual string ExpirationDate { get; set; } } And my Serialization attempt: XmlDocument Xmldoc = new XmlDocument(); Xmldoc.Load(string.Format(url)); string xml = Xmldoc.InnerXml; var serializer = new DataContractSerializer(typeof(License)); var memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)); License license = (License)serializer.ReadObject(memoryStream); memoryStream.Close(); The following elements are serialized: Guid ValidKey The following elements are not serialized: Url CurrentDate RegistrationDate ExpirationDate Replacing the string dates in the xml file with "blah" doesn't work either. What gives?

• LINQ-To-SQL and Mapping Table Deletions

  - by Jake

  I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

• Can't operator == be applied to generic types in C#?

  - by Hosam Aly

  According to the documentation of the == operator in MSDN, For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object. For the string type, == compares the values of the strings. User-defined value types can overload the == operator (see operator). So can user-defined reference types, although by default == behaves as described above for both predefined and user-defined reference types. So why does this code snippet fail to compile? void Compare<T>(T x, T y) { return x == y; } I get the error Operator '==' cannot be applied to operands of type 'T' and 'T'. I wonder why, since as far as I understand the == operator is predefined for all types? Edit: Thanks everybody. I didn't notice at first that the statement was about reference types only. I also thought that bit-by-bit comparison is provided for all value types, which I now know is not correct. But, in case I'm using a reference type, would the the == operator use the predefined reference comparison, or would it use the overloaded version of the operator if a type defined one? Edit 2: Through trial and error, we learned that the == operator will use the predefined reference comparison when using an unrestricted generic type. Actually, the compiler will use the best method it can find for the restricted type argument, but will look no further. For example, the code below will always print true, even when Test.test<B>(new B(), new B()) is called: class A { public static bool operator==(A x, A y) { return true; } } class B : A { public static bool operator==(B x, B y) { return false; } } class Test { void test<T>(T a, T b) where T : A { Console.WriteLine(a == b); } }

• Why does RunDLL32 process exit early on Windows 7?

  - by Vicky

  On Windows XP and Vista, I can run this code: STARTUPINFO si; PROCESS_INFORMATION pi; BOOL bResult = FALSE; ZeroMemory(&pi, sizeof(pi)); ZeroMemory(&si, sizeof(si)); si.cb = sizeof(STARTUPINFO); si.dwFlags = STARTF_USESHOWWINDOW; si.wShowWindow = SW_SHOW; bResult = CreateProcess(NULL, "rundll32.exe shell32.dll,Control_RunDLL modem.cpl", NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi); if (bResult) { WaitForSingleObject(pi.hProcess, INFINITE); CloseHandle(pi.hProcess); CloseHandle(pi.hThread); } and it operates as I would expect, i.e. the WaitForSingleObject does not return until the Modem Control Panel window has been closed by the user. On Windows 7, the same code, WaitForSingleObject returns straight away (with a return code of 0 indicating that the object signalled the requested state). Similarly, if I take it to the command line, on XP and Vista I can run start /wait rundll32.exe shell32.dll,Control_RunDLL modem.cpl and it does not return control to the command prompt until the Control Panel window is closed, but on Windows 7 it returns immediately. Is this a change in RunDll32? I know MS made some changes to RunDll32 in Windows 7 for UAC, and it looks from these experiments as though one of those changes might have involved spawning an additional process to display the window, and allowing the originating process to exit. The only thing that makes me think this might not be the case is that using a process explorer that shows the creation and destruction of processes, I do not see anything additional being created beyond the called rundll32 process itself. Any other way I can solve this? I just don't want the function to return until the control panel window is closed.

• Proof of library bug vs developer side application bug

  - by Paralife

  I have a problem with a specific java client library. I wont say here the problem or the name of the library because my question is a different one. Here is the situation: I have made a program that uses the library. The program is a class named 'WorkerThread' that extends Thread. To start it I have made a Main class that only contains a main() function that starts the thread and nothing else. The worker uses the library to perform comm with a server and get results. The problem appears when I want to run 2 WorkerThreads simultaneously. What I first did was to do this in the Main class: public class Main { public static void main(String args[]) { new WorkerThread().start(); // 1st thread. new WorkerThread().start(); // 2nd thread. } } When I run this, both threads produce irrational results and what is more , some results that should be received by 1st thread are received by the 2nd instead. If instead of the above, I just run 2 separate processes of one thread each, then everything works fine. Also: 1.There is no static class or method used inside WorkerThread that could cause the problem. My application consists of only the worker thread class and contains no static fields or methods 2.The library is supposed to be usable in a multithreaded environment. In my thread I just create a new instance of a library's class and then call methods on it. Nothing more. My question is this: Without knowing any details of my implementation, is the above situation and facts enough to prove that there is a bug in the library and not in my programm? Is it safe to assume that the library inside uses a static method or object that is indirectly shared by my 2 threads and this causes the problem? If no then in what hypothetical situation could the bug originate in the worker class code?

• COM Interop - Wait for Excel to Complete Operation

  - by roygbiv

  Hello, I am doing some COM Interop work with Excel and other Office Automation Software. A Co-Worker has mentioned to me that I need to wait for these Automation Servers to become ready after issuing a command to them. I, however, cannot see the purpose of this as don't all calls block until the automation server completes the given task? For example I would normally write: Dim o as AutomationObject = AutomationServer.CreateObject(x, y, z) o.Property ' could throw COM exception!!???? My co-worker says I need to sleep after that call because the the Automation Server could still be working on creating and initializing the object. Dim o as AutomationObject = AutomationServer.CreateObject(x, y, z) Threading.Sleep(5000) ' wait for AutomationServer to "become ready" o.Property ' could still throw COM exception!!???? The problem I have with this is that the AutomationServer calls should block until the AutomationServer finishes or completes what it was working on or at the very least it should be a loop checking if "o" is nothing, but that makes no sense because once the call returns its done! My question is, Is there any benefit to Sleeping after an AutomationServer call? Is there a method to "wait" until the AutomationServer finishes (if it does not in fact block)?

• How do I pass an array of structs (containing std:string or BSTR) from ATL to C#. SafeArray? Varian

  - by Andrew

  Hi, I have an ATL COM object that I am using from C#. The interface currently looks like: interface ICHASCom : IDispatch{ [id(1), helpstring("method Start")] HRESULT Start([in] BSTR name, [out,retval] VARIANT_BOOL* result); ... [id(4), helpstring("method GetCount")] HRESULT GetCount([out,retval] LONG* numPorts); ... [id(7), helpstring("method EnableLogging")] HRESULT EnableLogging([in] VARIANT_BOOL enableLogging); }; That is, it's a very simple interface. I also have some events that I send back too. Now, I would like to add something to the interface. In the ATL I have some results, which are currently structs and look like struct REPORT_LINE { string creationDate; string Id; string summary; }; All the members of the struct are std::string. I have an array of these that I need to get back to the C#. What's the best way to do this? I suspect someone is going to say, "hey, you can't just send std::string over COM like that. If so, fine, but what's the best way to modidfy the struct? Change the std::string to BSTR? And then how do I, 1) Set up the IDL to pass an array of structs (structs with BSTR or std::string) 2) If I must use SAFEARRAYS, how do I fill the SAFEARRAYS with the structs. I'm not familiar with COM except for use with simple types. Thanks, Dave

• Question about registering COM server and Add Reference to it in a C# project

  - by smwikipedia

  I build a COM server in raw C++, here is the procedure: (1) write an IDL file to define the interface and library. (2) use msidl.exe to compile the IDL file to necessary .h, .c, .tlb files. (3) implement the COM server in C++ and build a .dll file. (4) add the following registry entris: [HKEY_CLASSES_ROOT\RawComCarLib.ComCar.1\CurVer] @="RawComCarLib.ComCar.1" ;CLSID [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\InprocServer32] @="D:\com\Project01.dll" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\ProgID] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\TypeLib] @="{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}" ;TypeLib [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0] @="Car Server Type Lib" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="D:\com\Project01.tlb" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\FLAGS] @="0" [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="C:\Windows\System32\msdatsrc.tlb" (5) I try to add reference to the COM by click the Add Reference in the C# project. (6) In the COM tab, I saw my "Car Server Type Lib", it's ok until now. I try to use the Object Browser to browse my COM lib, but the Visual Studio said "the following components could not be browsed", and I noticed that there's no new reference added to the list in the C# project Reference. I can use the tlbimp.exe to generate a interop.CarCom.dll, and then use the COM through this interop dll, but I want this interop assembly to be generated automatically when I just add reference to the COM. Could someone tell me what's wrong? Many thanks.

• Android application transparency and window sizing at root level

  - by ajoburg

  Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the transparency and window sizing is done with activities that are not the root task and this works fine. However, the root task of an activity seems to always fill the whole screen and be black even when a transparent theme is applied to the application object in the manifest file. ApplicationManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:theme="@style/Theme.Transparent"> Styles.xml <resources> <style name="Theme.Transparent"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@drawable/ transparent_background</item> <item name="android:windowAnimationStyle">@android:style/ Animation.Translucent</item> <item name="android:colorForeground">#fff</item> <item name="android:windowIsFloating">true</item> <item name="android:gravity">bottom</item> </style> </resources> Colors.xml <resources> <drawable name="transparent_background">#00000000</drawable> </resources>

• Why does calling abort() on ajax request cause error in ASP.Net MVC (IE8)

  - by user169867

  I use jquery to post to an MVC controller action that returns a table of information. The user of the page triggers this by clicking on various links. In the event the user decides to click a bunch of these links in quick succession I wanted to cancel any previous ajax request that may not have finished. I've found that when I do this (although its fine from the client's POV) I will get errors on the web application saying that "The parameters dictionary contains a null entry for parameter srtCol of non-nullable type 'System.Int32'" Now the ajax post deffinately passes in all the parameters, and if I don't try and cancel the ajax request it works just fine. But if I do cancel the request by calling abort() on the XMLHttpRequest object that ajax() returns before it finishes I get the error from ASP.Net MVC. Example: //Cancel any pevious request if (req) { req.abort(); req = null; } //Make new request req= $.ajax({ type: 'POST', url: "/Myapp/GetTbl", data: {srtCol: srt, view: viewID}, success: OnSuccess, error: OnError, dataType: "html" }); I've noticed this only happen is IE8. In FF it seems to not cuase a problem. Does anyone know how to cancel an ajax request in IE8 without causing errors for MVC? Thanks for any help.

• Java Swing MVC question

  - by juFo

  I'm following this MVC model: http://java.sun.com/developer/technicalArticles/javase/mvc/ In my model I have an "ArrayList shapes" field and I need the shapes in my view. Is the only way of getting my shapes by getting them in the modelPropertyChange method? public void modelPropertyChange(PropertyChangeEvent evt) { if (evt.getPropertyName().equals(MyController.PROPERTY_TEXT)) { ArrayList<Shape> shapes = (ArrayList<Shape>) evt.getNewValue(); } } or should I also create a generic getter method in my controller? like this generic setter method: protected void setModelProperty(String propertyName, Object newValue) { for (AbstractModel model: registeredModels) { try { Method method = model.getClass(). getMethod("set"+propertyName, new Class[] { newValue.getClass() } ); method.invoke(model, newValue); } catch (Exception ex) { // Handle exception. } } } If I need such a generic getter method, I have no clue how to transform this generic setter above to a generic getter method. If I don't need such a generic getter method to retreive my data from the model, if I only need the modelPropertyChange method from my View. How would I get my data from the model the first time the application starts? :o Pfft I need to get my arraylist of shapes from my model in my view :( (and later I need to get some other data also) So confusing :(

• 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.

• Save as DialogBox to save textbox content to a newfile using asp.net

  - by user195114

  I want the users to type their text in the given textbox and on clicking on createNewFile Button, a SaveAs Dialogbox should popup and the users should browse through the location and save the file as desired. I have tried some thing but (1) the dialog box goes behind the application (2) when run, dialogbox opens 3 times, means it executes 3 times REPLY TO THE POST protected void btnNewFile_Click(object sender, EventArgs e) { StreamWriter sw = null; try { SaveFileDialog sdlg = new SaveFileDialog(); DialogResult result = sdlg.ShowDialog(); sdlg.InitialDirectory = @"C:\"; sdlg.AddExtension = true; sdlg.CheckPathExists = true; sdlg.CreatePrompt = false; sdlg.OverwritePrompt = true; sdlg.ValidateNames = true; sdlg.ShowHelp = true; sdlg.DefaultExt = "txt"; // sdlg.ShowDialog = Form.ActiveForm; string file = sdlg.FileName.ToString(); string data = txtNewFile.Text; if (sdlg.ShowDialog() == DialogResult.OK) { sw.WriteLine(txtNewFile.Text); sw.Close(); } if (sdlg.ShowDialog() == DialogResult.Cancel) { sw.Dispose(); } //Save(file, data); } catch { } finally { if (sw != null) { sw.Close(); } } } private void Save(string file, string data) { StreamWriter writer = new StreamWriter(file); SaveFileDialog sdlg1 = new SaveFileDialog(); try { if (sdlg1.ShowDialog() == DialogResult.OK) { writer.Write(data); writer.Close(); } else writer.Dispose(); } catch (Exception xp) { MessageBox.Show(xp.Message); } finally { if (writer != null) { writer.Close(); } } } I have tried this.

• Setting article properties for a publication using RMO in C# .NET

  - by Pavan Kumar

  I am using transaction replication with push subscription. I am developing a UI for replication using RMO in C#.NET between different instances of the same database within same machine holding similar schema and structure. I am using Single subscriber and multiple publisher topology. During creation of publication i want to set a few article properties such as Keep the existing object unchanged ,allow schema changes at subscriber to false a,copy foriegn key constarint and copy check constraints to true. How do i set the article properties using RMO in C# .NET. I am using Visual Studio 2008 SP1.I also want to know as how we can select all the objects including Tables,Views,Stored Procedures for publishing at one stretch. I could do it for one table but i want to select all the tables at one stretch. This is the code snippet i used for selecting single table for publishing. TransArticle ta = new TransArticle(); ta.Name = "Article_1"; ta.PublicationName = "TransReplication_DB2"; ta.DatabaseName = "DB2"; ta.SourceObjectName = "person"; ta.SourceObjectOwner = "dbo"; ta.ConnectionContext = conn; ta.Create();
