  • Difference between ISupportInitialize (BeginInit/EndInit) and SuspendLayout/ResumeLayout

    - by Pato
    Hello All! Could someone please explain what the difference is between using the ISupportInitialize interface methods (BeginInit/EndInit) and using SuspendLayout/ResumeLayout? Is ISupportInitialize ONLY used during construction/"initial" initialization... or can it be used later when you want to add new child controls to an existing parent control? Any particular differences? I greatly appreciate your help! Thank you, Pato

    With a windows MSI file, is there a way to grab all the possible installation parameters in .NET code? I need to make a generic user interface to configure multiple MSI files not known until run-time – then install them together in one go.

  • Translating a C# WCF app into Visual Basic

    - by MikeG
    I'm trying to write a simple/small Windows Communication Foundation service application in Visual Basic (but I am very novice in VB) and all the good examples I've found on the net are written in C#. So far I've gotten my WCF service application working but now I'm trying to add callback functionality and the program has gotten more complicated. In the C# example code I understand how everything works but I am having trouble translating into VB the portion of code that uses a delegate. Can someone please show the VB equivalent? Here is the C# code sample I'm using for reference: namespace WCFCallbacks { using System; using System.ServiceModel; [ServiceContract(CallbackContract = typeof(IMessageCallback))] public interface IMessage { [OperationContract] void AddMessage(string message); [OperationContract] bool Subscribe(); [OperationContract] bool Unsubscribe(); } interface IMessageCallback { [OperationContract(IsOneWay = true)] void OnMessageAdded(string message, DateTime timestamp); } } namespace WCFCallbacks { using System; using System.Collections.Generic; using System.ServiceModel; public class MessageService : IMessage { private static readonly List<IMessageCallback> subscribers = new List<IMessageCallback>(); //The code in this AddMessage method is what I'd like to see re-written in VB... public void AddMessage(string message) { subscribers.ForEach(delegate(IMessageCallback callback) { if (((ICommunicationObject)callback).State == CommunicationState.Opened) { callback.OnMessageAdded(message, DateTime.Now); } else { subscribers.Remove(callback); } }); } public bool Subscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Add(callback); return true; } catch { return false; } } public bool Unsubscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Remove(callback); return true; } catch { return false; } } } } I was thinking I could do something like this but I don't know how to pass the message string from AddMessage to DoSomething... Dim subscribers As New List(Of IMessageCallback) Public Sub AddMessage(ByVal message As String) Implements IMessage.AddMessage Dim action As Action(Of IMessageCallback) action = AddressOf DoSomething subscribers.ForEach(action) 'Or this instead of the above three lines: 'subscribers.ForEach(AddressOf DoSomething) End Sub Public Sub DoSomething(ByVal callback As IMessageCallback) 'I am also confused by: '((ICommunicationObject)callback).State 'Is that casting the callback object as type ICommunicationObject? 'How is that done in VB? End Sub

  • Convert Java.Util.HashMap to System.Collections.IDictionary

    - by Paul
    In Xamarin I've got a .jar I've imported using a Java Binding Library. One of the callbacks has a Java.Lang.Object parameter which gives me Java.Util.HashMap and Java.Util.ArrayList at runtime. I'm abstracting this SDK behind a cross-platform interface, so I need to convert this to a .NET type. It there anything like the ArrayAdapter except in reverse that can convert the Java types to their .NET equivalents?

  • Creating a calendar in PHP

    - by Chris T
    Are there any APIs or libraries that make it easy to generate a calendar for a certain month/year? I need to have some sort of admin interface for a "event planner" part of a CMS for a local youth group and I'm at a loss as to how to generate a decent calendar. Note: I only need something to generate the calendar HTML, not manage events. I'll be coding that part.

  • Do you put #import s in .h or .m files?

    - by iter
    I wonder about Objective-C style. I have FooClass.[hm] that depends on BarClass.[hm] for its implementation (though not for its interface). I can #import "BarClass.h" either directly in FooClass.m or indirectly through FooClass.h. I wonder about the common choice for this.

  • Recipes/tutorials/libraries for GUI-like terminal navigation (vim/lynx-style)?

    - by qgi
    Several console based applications like vim or lynx offer a rich user interface which enables the user to navigate freely around the console, manipulate data directly on screen, access menus and much more, similar to "modern" gui applications. How is that being achieved in principal on Unix/Linux with C++? Do you directly manipulate some kind of character buffer or is the screen constantly cleared and reprinted to stdout? Is there a set of libraries to implement such behavior or even some kind of a "modern" event-driven GUI toolkit for the console?

    I'm looking for a JVM profiler (preferably open source) so I can look at the heap and cpu usage of my personal website. I've used Lambda Probe, and I like it because it provides a web interface for my remote Unix computer that has no display. I was wondering what else is available Thanks,

  • Store Observer not being called always

    - by Nixarn
    Has anyone else here experienced problems with their Store Observer class not being called always when the user for instance cancels a request (or purchases something) We just had our update that brought in app purchases go live last night, and before that we had obviously tested everything tons of times against the Sandbox and everything was working fine. Now however, when the update went live in a real environment we keep getting issues with the store. For instance, in a freshly booted iPhone / iPod, the first time you run the app, if you then try to make a purchase and then immediately cancel it from the first dialog, it seems as if the callback for the cancel is not getting called. If you then restart the app it seems as if it always works after that, or at least. Same thing with other callbacks, seems as if our store observer isn't listening as the callbacks aren't being registered on the phone. One example of this is if you purchase something, then nothing will happen (if this is the first time the app is launched at least). You get the purchase successful dialog from the app store but it seems as if our own code isn't called. If you then quit the app and restart it the callback gets called. Same problem happens if you for instance try to start a request to download all previous purchases and then immediately cancel it as the first dialog pops up, if you do that then the callback for a failed restore is not called, until you then restart the app and try it again, then it always seems to work. The way we have implemented our store observer is by creating a custom class that's implements the SKPaymentTransactionObserver interface. @interface StoreObserver : NSObject<SKPaymentTransactionObserver> In the class we have implemented the following methods: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions - (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error The way our restore process works is that if you tap on the button that allows you to download all we simply run the restoreCompletedTransactions code as follows: [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; However, the callback, restoreCompletedTransactionsFailedWithError, which has been implemented in the store observer, does not always get called when we try to cancel the request. This happens when you boot the iPhone / iPod and try this for the first time. If you after that restart the app everything works fine. The StoreObserver class is created when our app is launched, just by running the following code: pStoreObserver = [[StoreObserver alloc] init]; [[SKPaymentQueue defaultQueue] addTransactionObserver:pStoreObserver]; Has anyone else had any similar experiences? Or does anyone have any suggestions on how to solve this? As I said, in the sandbox environment everything was working fine, no issues whatsoever, but now once it's gone live we're experiencing these.

  • Folder Sharing NTFS permissions with Share Permission

    - by Muhammad Adly
    i have a problem on my domain, the history starting from when i had a server with WIN 2008 r2 installed with the following roles installed on it (AD, DNS, DHCP, File). From 1 month i decided to install a new server 2008 r2 server to get (AD, DNS, DHCP) and leave the file server on the old one. i did the following exactly: 1) robocopy all my data on external HDD 2) Install a new server with 2008 r2 3) transfer all 5 roles to transfer the domain to the new server (MainDC) 4) issue (NETLOGON, SYSVOL) not transferred but i decided to reinitialize them again an now they are operating (MainDC) 5) re-create and re-configure a new GPOs and link it to my OUs 6) reinstall Old server operating system with a fresh installation of WIN 2008 R2 (FileServer) 7) join my domain with my domain credentials. the issue when i tried to share folder on \fileserver the permissions that i had set in sharing permissions are applied on the main shared folder and subfolders. the security settings are not applied. i.e. Say i'm sharing \fileserver\MainFolder with sharing permission for Authenticated Users that can read, so every one can read this main shared folder, if i set security permission for \fileserver\MainFolder\User1 that User1 can Read\Write\Modify. User1 can not perform this processes when accessing it from Network Share, i tried alot of steps from topics online get ownership for folder, remove inheritance from parent folder, applying changes for child objects, i tried also to construct a new folder structure but also the same issue, i tried another host PC, also i get the same issue.

  • Java Interfaces Methodology

    - by Amir Rachum
    Hi all, I've been programming in Java for a few courses in the University and I have the following question: Is it methodologically accepted that every class should implement an interface? Is it considered bad practice not to do so? Can you describe a situation where it's not a good idea to use interfaces? Thanks.
