Create An Interface In VBNet With Implicit Implementations?
Jun 20, 2012
Possible Duplicate: How can I create an interface in VBNet with implicit implimentations I'm normally a C# developer and completely new to VB.NET, so be nice with me.;) Let's say that I have this base class:
[Code]....
Is there any way of not having to use these "proxy"-calls to the real method? I haven't found any useful information about this in the CLI-specification, which makes me suspect that this is a VB.NET "feature". Is this the case?
In C# I can create an interface, and when I use the interface the compiler knows that certain interface requirements are fulfilled by the base class. This is probably clearer with an example:
[Code]...
On all my forms, or is a better route creating an abstract base class that has SetupForm() (and how do you do that in VB.net)?
I would like to know what are the usages for Threading or BackgroundWorker, and their implementations.I currently am running a UDP program, but the server freezes until the client sends the packet, which momentarily unfreezes the server, and then re freezes it.I have looked at the MSDN for them and they seem complicated :l
is it ever possible to write locking-features(for threading) with the language itself (this question is purely academic, I know no one will ever do it even if its possible (not me))?
A) In Java, is it possible to write thread safety functions with java alone, but without using any of the provided classes/language elements/syntax which offer this feature?
B) In C#, is it possible to write thread safety functions with C# alone, but without using any of the provided classes/language elements/syntax which offer this feature?
C) In Vb, is it possible to write thread safety functions with Vb alone, but without using any of the provided classes/language elements/syntax which offer this feature?
Recently, I Developed an Experiment Application with VB.net(in Windows platform), When the application collected the data,I want to use R to Analysis the data, But I don't know how to Communicate with R (In other word, I want to send R script to R in my own application).
One of the convenient and simple events I liked for textboxes in VB6 and VBA was the afterupdate event where after you finished typing in your data or text, you pressed enter and the program processed the text in the textbox. In VBNet, life is not so simple. I have included a simple code to do the same thing using the keydown event and checking to see if it is the enter key. This code just send a message box with all the text in it. You can manage things from there
This is probably simple, but the answer has eluded me. How can I move a folder from one drive to another drive. System.IO's MoveTo won't let me move a folder to another volume. Any thoughts?[URL]..

I have a VBnet program that works fine and I'm hellbent on getting it to run under Linux eventually (looks like mono is the way to go sometime soon). But, for now, I'm looking at some of these code converters, online and otherwise and have some questions.
I tried a single procedure of code with the online converter and it threw quite a few errors relating to the procedure lines themselves (the opening Private sub etc, etc,)Something about C# and handles clauses -- can't remember.
So, I suppose the online converter just wants to see the code itself? As in, what lies between the Private sub blah -- CODE -- end sub?Now, what about something I saw this morning, "Sharpdevelop" that says it can convert entire PROJECTS to C#? (Also saw a 200.00 software package as well).
Is that the way to go? Will it do every bit of the project's code start to finish? You just load the project folder or the project file I guess?But then I see Sharpdevelop doesn't compile -- so you convert with it and then open the converted file with Visual studio C#.net?
I guess Microsoft will never have this conversion capability in visual studio?
This is what happened: on the form load of my application i created a background worker to bind collection (records from database filled in the dataset) on my control. but the problem is when the i updated the records on the database it throws an error if i run this procedure again.
If xControl.InvokeRequired Then Dim MyDelegate As New InitializeDataBinding_Delegate(AddressOf InitializeDataBinding) Invoke(MyDelegate, New Object() {xControl, xQuery, xPrimaryKey}) ' ERROR HERE SAYING: Collection was modified; enumeration operation may not execute.

I've already tried to use the datagridview but i cant add rows..(unless the user input a data in every row). please tell me how to manipulate the datagridview for me to able to add rows and columns automatically...
I would like to create an interface that brings with it it's own private variables and regions.for example, if you create a class and implement IDisposable, you get all of the following:[code]
I need to build an interface that allows the user to select a horse from a list. The horses are as follows: horse1, horse2, horse3 and horse4. The application should display the way the horse places with a 1 means the horse won, 2 indicates second place , 3 indicates third and 0 indicates the horse did not place. Application needs to display a summary of each horse's individual performance as well as the performances of the other horses. Table for keeping track of each horse is as follows:

I am trying to create an interface between a third party application which can make use of C/C++ DLLs, but no interface directly to .NET. What I was hoping to accomplish (not sure if possible though), is create a very basic C++ DLL (not .NET), which the third party application would call directly. This DLL would contain a basic method such as "DoSomething()". Somehow, from my .NET application, I want to "listen" to this DLL and "takeover" the DoSomething() method, and then returning the result back to the DLL, which will in turn return the result back to the calling third party application.
I don't even know if this is possible because I'm sure I would somehow have to get a hold of the memory space of the DLL as initiated by the third party application. Also, it seems that creating a managed DLL does not work, based on feedback from other individuals who have tried this.
This is a followup to this thread, where I'm trying to draw two sets of dots using HatchBrushes to create VS2010-like interface. If you take a look at the zoomed image of the IDE background (blue with dark and light blue dots): that is what I'm trying to draw using GDI+. In the previous thread ForumAccount find the correct HashStyle to use (Percent20), but there is a problem: I need to draw two sets of these hatchstyles: once with a slightly darker color and once with a slightly lighter color, at an offset of one pixel downwards.
I am trying to build a user control that will do exactly what the SQL 2005 Connect to Server interface do, eventually create a connection string and store in a app.config file. It should allow user to select server type, server name, authentication, user name and password. It should also automatically load available servers and domain login by default.
