    - "Importing" my existing classes to a dbml? Hi, I'm currently moving (slowly) to use Linq to Sql to replace my custom data access layer. Fortunately, my DAL worked very similar to L2S as far as the use of classes goes; each table is decorated with attributes that tell my DAL how to do what it needs. At first glance, it seemed all I had to do was slap the Table and Column attributes onto my classes, and I could use both Linq and my DAL as I transition. I'm now at the point where I'm creating associations and going to be using Linq to update data, not just read it. I hit a problem, which I think was caused because my backing field for the ONE side of a relationship was MyTable, not EntityRef<MyTable>. Ok, I can fix that, I've only done a few classes. Now I'm looking at the EntitySet side of things. Here it seems more complex; initially I had simply the field for EntitySet<MyTable2>. But it looks like other code is could be needed, such as specifying actions for insert and delete and implementing IPropertyChanging and IPropertyChanged. So.. is there any way to automate getting this code in? Do my data access classes HAVE to be in the Dbml.designer.cs file, all in the same namespace? What are my options here?

    - Question, old programming books for beginnner okay? Hi, I have a couple of csharp books for beginners that I never used. They were published around the 1.0 framework era. Would I be doing a friend a disservice by giving him these books? ie. should he buy more recently published books instead or will the ones I have be okay. I would hate for him to use these books and then feel like he's having to relearn 3.0 framework code. I'm not a programmer myself so I really don't know how much is changed or whatever. I heard was they included more namespaces and chagned some syntax? I'm hoping that since they're beginner books, most of the code samples and training will not be dramatically affected by newer framework versions. Thanks a lot. p.s. oh, if you don't recommend using the old books please recommend new ones. Books are Learning C# - Jesse Liberty C# By Dissection - Ira Pohl Tag: Datasets and Excel Tag: 545675

    - EventWaitHandle.OpenExisting oddity I have an application (lets call it app_1) that creates a named event using the EventWaitHandle class and friends. I use it to determine from other external apps if app_1 is still running. I do it by performing an EventWaitHandle.OpenExisting on the said named event. The problem is even after app_1 is shut down (the named event is properly closed before app_1 exits) doing EventWaitHandle.OpenExisting from other external applications still succeeds! This is a problem for me because now I can no longer rely on the absence of the event to tell me if app_1 is running or not. Why is the event still hanging around? I know there are other ways to detect if a process is running or not but I want to know why this won't work. Tag: Datasets and Excel Tag: 545674

    - How to trap error that invokes the Send Error Report To Microsoft? Hi, My C# application trys to access directorycontext during Form loading. Try and Catch if there is an exception. I then output an error message and then "this.Close();" to exit the application. But, as my applicaiton closes, the MS dialog comes up asking to send Error Report to MS. I tried using ThreadException event code from: http://msdn2.microsoft.com/en-us/library/system.windows.forms.application.threadexception.aspx But I'm getting compiling message: The name ErrorhandlerFrom does not exist in the current context. This is from the line of code: // Add the event handler for handling UI thread exceptions to the event. Application.ThreadException += new ThreadExceptionEventHandler(ErrorHandlerForm.Form1_UIThreadException); How to address that? What is ErrorHandlerForm? I can't find answer to the ErrorHandlerForm so I tried commenting that line out and I put a try catch around my code(including Application.Run) in program.cs. Now the MS Error Report dialog does't come up. Why is that so? And also, is it OK to put a try-catch around Application.Run? Thank you. -- Thanks. Tag: Datasets and Excel Tag: 545671

    - defining objects with xml/schema This is more of wanting to get some opinions and if anyone has run into the same design issue. I need to have about a hundred c# classes that simply represent an object and contain data (no methods). These objects will be modified pretty often by alot of different people and need to be serialized/deserialized to binary and xml. I basically have three options: 1. write the classes in c# 2. represent the classes in xml and auto-generate them 3. represent the classes in xsd and auto-generate them option 1 can be done but gets very reptitive and messy when there are many sub-objects. option 2 gives a very clear representation of the object and is easy for other people to modify/add new fields, however does not contain enough data to distinguish the types that are generated (data type, array, etc.). option 3 does the job but is so hard to visualize and maintain/modify and will be hard for other people who don't have a grasp of xsd schema. plus xsd schema is really to represent xml and not a programmable object. I was thinking of representing my object with a hybrid of xml and xsd and having a custom generator like xsd.exe create the c# objects. an object could look like this... <myobject> <item1>xs:type=boolean</item1> <item2 myattr1="xs:type=dateTime">xs:type=string</item2> <item3> <item4 xs:array>xs:type=mytype</item4> </item3> something like that...of course "xs:" could be something different but indicates a code generator option. it would produce somethig like... class myobject { public bool item1 {get; set;} public item2Object {get;set;} public item3Object {get;set;} public class item2Object { [XmlAttribute] public bool myattr1 {get; set;} [XmlText] public string Value {get;set;} } public class item3Object { public List<mytype> item4 {get; set;} } } I think that would give a good flexible way of generating objects that could be easily maintained and easily compared for backward compatibility problems. any thoughts?

    - Little beginner's query I have successfully created a small application that uses arraylists of objects. However I have found it quite tiresome , when modifying one of the objects in the arraylist to have to assign it to a temporary instance before re-writing it. something like... temp_object1 = (object1) object1_arraylist[10] temp_object1.element = "Something else" object1_arraylist[10] = temp_object1 because it seems impossible to simply code: (object1_arraylist[10]).element = "Something else" Is there a simple way round this? Would pointers help? Thanks for the tip! steve tanner Tag: Datasets and Excel Tag: 545651

    - How to add a COM user control to a form Hi, I have a COM dll written in C#, I compiled it from its source as .Net2 in VS2008. It is a User control derived from System.Windows.Forms.UserControl I compile it as a class library, with COM Interop, VS2008 creates beutifully dll and tlb for that. To be able to "run", test an ddebug it: I added a Windows Form Project, which will "call" this usercontrol under the same solution. (Just by Add, New Project, Windows Forms Application. The IDE created a beautiful empty form.). I added a project reference to the COM control above (IDE has not allowed to add it as a COM reference.) How do I add, (or embed) the earlier COM user control into that beutiful empty Form1? And: How do I handle in the Form1 the COM ButtonClicked() event, which is an [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] public interface IContainerEvents Any hints appreciated.

    - Importing forms from vs2005 > vs2008 manually. How do i make vs2008 recognise them as forms? Im moving an application from VS2005 to VS2008. Im recreating my projects manually as I've had problems in the past allowing VS to update my application automatically I copy the xxx.cs, xxx.designer.cs and xxx.resx files for a form to the new project directory. I only add the .cs file to the project and VS2008 automatically picks up the other 2 files and places them in subnodes in the solution explorer. But, the icon shown in solution explorer is that for a class/code file and when I double click on it I dont get my form shown. I only see the code in the cs file. If I add all 3 files to the project then a base node is created for each of the 3 files. How do I add a form properly please? Tag: Datasets and Excel Tag: 545639

    - Using Reflection on FieldInfo I have a windows form that uses several typed datasets which generates the usual Designer code. I need to reference these objects elsewhere in my code. I was successful (partially) in using reflection and field info: System.Reflection.FieldInfo[] fi = this.GetType().GetFields(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Public); for (int i = 0; i < fi.Length; i++) { System.Diagnostics.Debug.WriteLine(string.Format("{0}", fi[i].FieldType)); } This allows me to see each of the objects on the form which is good. My question specifically is how do I reference those objects to store them in a collection? I'm particularily interested in the typed DataSet Objects, the typed BindingSources, and the typed TableAdapters. The problem is that the designer code resolves to a type of Form1.EmployeeDataSetTableAdapters.EmployeeBaseTableAdapter causing a problem when I want to store them in a collection. Please help Im really stuck here. Thank you! Ron Tag: Datasets and Excel Tag: 545632

    - Creating struct instead of class using ModuleBuilder.DefineType Hi I am trying to dynamically create a struct using the following code: TypeBuilder typeBuilder = moduleBuilder.DefineType("MyStruct", TypeAttributes.Public); It appears that this method will only ever create classes for me. Is there any way of dynamically creating a struct? I noticed that other constructs such as enums have their own equivalent define method (DefineEnum), but couldn't see a way of doing this for structs. I have to use a struct as this object is passed to a FORTRAN DLL which does not like the class equivalent. Best regards Marek Tag: Datasets and Excel Tag: 545618

    - newbie thats needs a little help with a dll issue Hello All, First, I'm newer than a Newbie... I know its sad, but i'm trying to start somewhere. I'm attempting to write what I thought was a very simple program that would call another program from a command line. Now I got that part to work, but got hung up on packaging the exe (and its supporting dll) to the target computer. So I found an open source program that extracts and create cab files. So using that I created a small progy to create the cab file containing the the two other files I need. Then modified my code to call the dll file that I included into the program(the cab extractor program.. I might also mention that the open source program is writen in C++ not C# and comes as a dll file that I included into my project). Everything was working fine till I moved my program to another computer and discovered that the dll file from the cab program is not included in my exe file. It has to be copied to the same directory as my exe. So does anyone know how integrate that dll file into my exe, or a way to include it as a resource file and extract it to the working directory(i've search high and low for that and can not find anything). I've tried to use the al.exe program included with the SDK's in VS08 but its fighting me every step of the way. I keep getting caught up on finding the main entry point. The main entry point in my app is under the program.cs class - method main. So in the al.exe command line I include "/main:program.main" like the tech net article refers to.. but it keeps erroring out. If anyone has suggestions please respond. I could use a little help before the sanity fails!!! LOL Thanks, Aaron Tag: Datasets and Excel Tag: 545611

    - Driving a C# application using an unmanaged MFC application Hi We have a C# application that we need to "drive" using an MFC application.

It would also be good if the C# application could somehow post/fire messages/events back to the MFC application.

    - Do I need to manually escape special characters for I have an .MDB which has a table, and let VS.NET generate all the necessary classes for my DataGridView. Now, I want to filter the rows on user's requests. I could simply use .Filter property, like .Filter = "ColumnName ='%" + keyword + "%'"; But come to think of it, the keyword, which is input by users, could contain characters like ', % or whatever special characters that the Filter method uses. Do I need to manually escape special characters for BindingSource.Filter? As told before I should not reinvent the wheel, if there already is a method for this, I would like to use that. Escaping special characters should be required for all applications like this so I thought there probably be a method. I tried to find a method like that would do that, but couldn't find any. Would you please give me an advice? Tag: Datasets and Excel Tag: 545598

    - Confused about ComboBox and DataBinding I'm surprised that I'm having trouble with this, I suspect that I'm having a major brain fart and expecting something to work a way it doesn't. In my example, I have a List<> of custom objects bound to a ComboBox. I then have a single instance of the custom object which I have bound to the SelectedItem property. I'm expecting: 1) When the user changes the selection from the drop down the single, bound instance will reference the selected item from the bound collection. 2) When binding the control to the single instance, it should select the item in the list that matches (if there is one) Here is a very simple example. I didn't include all the WinForm stuff, as long as you have a ComboBox names comboBox1 it should be cut and paste. <code> List<SomeObject> _objects; SomeObject _object; public Form1() { InitializeComponent(); _objects = new List<SomeObject>(); _object = new SomeObject("C", 3); _objects.Add(new SomeObject("A", 1)); _objects.Add(new SomeObject("B", 2)); _objects.Add(new SomeObject("C", 3)); _objects.Add(new SomeObject("D", 4)); comboBox1.DataSource = _objects; comboBox1.ValueMember = "Value"; comboBox1.DisplayMember = "Display"; comboBox1.DataBindings.Add(new Binding("SelectedItem", _object, "Value")); comboBox1.SelectedIndexChanged += delegate(object sender, EventArgs e) { MessageBox.Show(string.Format("_object.Value = {0}\n_object.Display = {1}", _object.Value, _object.Display)); }; } public class SomeObject { private string _display; private int _value; public SomeObject(string display, int value) { _display = display; _value = value; } public string Display { get { return _display; } set { _display = value; } } public int Value { get { return _value; } set { _value = value; } } } </code> If I change the code to use SelectedValue then it will select the correct item in the list, however making a new selection in the list does not update the _object reference OR it's Value property. If anyone can straighten me out on this I'd really appreciate it, I'm going in circles over here! ;0) -Steve Tag: Datasets and Excel Tag: 545576

    - Implementing Unmanaged Interface in C# Hi, I have an unmanged interface which i have exposed through COM to C#.

But now what i want to do is that i need to pass the reference of the object of Class1 to this COM wrapper...and then from inside that wrapper i want to call one of the func of that class1.

    - Namespaces and Inheritance Is it perfectly acceptable, from a "conventions" or "best practices" point of view to have a class in one namespace extend a class in another namespace? I just came across this state of affairs in the .NET Framework itself and, at first, it seemed somehow like a "bad thing" (in part because namespaces are intended to group classes that serve some common purpose) - but after about two seconds of thinking about it, I'm thinking that there is absolutely nothing wrong with doing this - and in many situations, like in large frameworks, it would even be unavoidable. And example from the .NET Frameowork is: System.ComponentModel.ComponentResourceManager which extends System.Resources.ResourceManager Thoughts? Opinions? - specifically regarding the idea that it is (or is not) perfectly acceptable to have a base class in one namespace, and then extend that class in an entirely different namespace? FWIW, I do understand that the classes, themselves, don't care about the namespace in which they exist - at least not beyond qualifying references to specific external classes. Thanks.

    - Thread Question - When do they die? I have some code that looks like this: int[] customerIds = { 1, 2, 3, 4, 5, 6, 7, 8 }; List<Thread> threads = new List<Threads>(); foreach (int customerId in customerIds) { Thread thread = new Thread(delegate() { // do calculation with customerId }); threads.Add(thread); thread.Start(); } foreach (Thread thread in threads) { thread.Join(); } First, when I run this code, it appears as though 8 is executed multiple times. My guess is that the thread continues on after the delegate finishes, and since MoveNext() on the List<int> just returns the last item over an over, we see 8 multiple times. Is that accurate? Furthermore, something seems wrong about storing threads in a List<Thread> and then joining. Is there a better way to Join these theads without keeping a reference to them around?

If so, how would I determine if this application supports it? The only way I can think to automate it is to enumerate all the windows on the system in a combo box, have the user select one and then send WM_LDOUBLECLICK and WM_KEYDOWN via pinvoking sendMessage or PostMessage (which one?) to the application. Is there a better way to do this? Thanks, Siegfried Tag: Datasets and Excel Tag: 545533

    - Factory method question I'm needing a little bit of clarity on using the factory design method. Lets say I have two concrete classes that implement an interface. Then I have two factories that instantiate objects of that type. I would like to have the two factories adhere to a common interface for creating the objects but the problem is that each object requires different parameters for the constructors. I could remove the different parameters and create common method signatures but then I am forced to have the calling class finish creating the object which seems dumb. The other thing I was thinking is passing in a "params" of Dictionary<string,object> objects that correspond to the other fields required for creating the object. Does this defeat the factory method? Thanks! Tag: Datasets and Excel Tag: 545518

    - Encoder - Removal?? I have a C# application that uses Windows Media Encoder 9 to stream multiple programs. For each new program, I create a new instance of WMEncoder. After successfully stopping the Encoder, what is the proper way to remove it for Garbage Collection? Currently I set Encoder = null and Garbage Collection should remove it from what I understand. I have not been able to get rid of the new Encoder instances and this creates a memory leak. Please help. Is there any good documentation out there dealing with Interop.WMEncoderLib? I haven't found any yet or good C# code examples dealing with this matter. Is there a function of Dispose or something similar for the Encoder? I need to figure out the correct way to release all the resources of the Encoder. Thanks, Bob Bob Tag: Datasets and Excel Tag: 545515

    - arraylist Hi, hopefully Ill explain my question ok. Im using an arraylist to get an an array of values from an application, which allows me to use a com interface to interact with its functions. I have no access to the code. I use prices.Add(ba.getPrices());, prices bieng my arraylist. It returns 1 element, which has 6 dimensions. I think thats the wording. So within prices[0] there is 6 dimensions, 0 to 5. When I use prices.count it returns 1, how do I get the count of the dimensions. Regards Robert Tag: Datasets and Excel Tag: 545510

    - Textbox databinding Hi all! I am having problem with textbox databinding. I have the following tables: - Order: CustomerID (and other fields) - Customer: CustomerID, Name, Address, CityID (and other fields) - City: CityID, Name, State I have a datagridview with "Order" rows, and a form with "Customer" and "City" fields. "Name" is a combobox where DisplayMember is "Name" and ValueMember is "CustomerID". "Address" is a textbox and the City fields are textbox too. First question: when I apply a filter on the datagridview, and there is no rows, the "Address" textbox is not clean (combobox "Name" is empty). Second question: how can I bind City fields?

    - Hosting Workflow Designers and Context Menus I have an application that hosts Workflow Designer and it shows the workflow visually. I am trying to add context menus for some of the Activities. The context menu will vary based on the Activity Types. And when the user selects any of the context menus, I would like to fire events and would like to know the Activity information (Name or type etc.) I know using CustomMessageFilter one can add context menu: protected override bool OnShowContextMenu(Point menuPoint) { ContextMenu _contextMenu = new ContextMenu(new MenuItem[] { new MenuItem("Pause") }); _contextMenu.Show(workflowView, menuPoint); return true; } The menu will be created in a particular a Point (OnShowContextMenu(Point menuPoint)) But my question is - how can I change this context menu based on the Activity Clicked (not based on the Points) Thanks Tag: Datasets and Excel Tag: 545507

    - Singleton Question I am trying to implement a singleton pattern in my application. I need to make sure that this class is both thread safe and ensure that only 1 instance can created at any given time. As you can see below I create a two instances of the singleton class, s1 and s2. Both s1 and s2 are indeed the same instance as I expected. However, when s2 changes the Count to 2, the count for S1 also changes to 2!!! This is the part I am confused about since I would expect this singleton to be thread safe....the fact that the s2 instance changed the value in s1 will cause problems in a multithreaded app. Am I missing something here? How do I prevent s2 and subsequent instances making changes to my singleton while s1 has a lock on it? ==== my singleton class ==== using System; using System.Collections.Generic; using System.Linq; using System.Text; class Singleton { private static Singleton instance; // Note: Constructor is 'protected' protected Singleton() { } public int Count { get; set; } public static Singleton Instance() { lock(typeof(Singleton)) { // Use Lazy initialization if (instance == null) instance = new Singleton(); lock(instance) { return instance; } } } } ==== test code ==== // Constructor is protected -- cannot use new Singleton s1 = Singleton.Instance(); s1.Count = 1; Singleton s2 = Singleton.Instance(); s2.Count = 2; int i = s1.Count; //2nd instance changed my s1 count? I thought locking would prevent this? if (s1 == s2) { Console.WriteLine("Objects are the same instance"); } // Wait for user Console.Read(); Tag: Datasets and Excel Tag: 545501

However, change the LINQ to the following and the correct values are shown: var procs = from process in System.Diagnostics.Process.GetProcesses() select new {process.ProcessName}; Can anyone shed some light on this? I am sure I am missing something obvious. Thanks, Chris Tag: Datasets and Excel Tag: 545498

I might have a situation where in there will be 1000 sheets and each
sheet might have 65000 records. Can you please let me know the best
practices that i can follow making sure that memory and performance
issues can be taken care of ?

Any help or reference is highly appreciated.

Thank you,
Ratnakar.
