It's more expressive but it is certainly not easier.

I wander - if i write those two lines
a. Object o1;
b. o1 = new Object();
1. In line a - the o1 is initialized to null - is this pointer will be allocate on stack in this place ?
2. when i write "new Object()" ( line b )- is in this step i allocate the new object on the heap ?
Thanks.

assuming both statements are inside some method:
1. yes the pointer resides on the stack, and no it is not initialized; only class members get initialized to zero/null/Nothing
2. yes
I suggest you buy and study a tutorial book on one of the .NET languages; it will explain it all, step by step, in a systematic way.

Like Luc said, it depends on where you write them.
And o1 is not initialized to anything, meaning it could have Any value (leftover bits from values that used to be on the stack but are now just hanging around), but you're not allowed* to use it (it's an error if you do, will not compile) so you won't see this value.
* well, there is unsafe code. In all the test I did (not that many..) it was just 0 anyway but that's not something I'd rely on.

Hello I'm a beginner with VB, and I was wondering if someone can help me?
How can you count and display the amount of times that the save button is clicked?
Thank you in advance, Aaron

Hopefully your plan for learning computer programming is not based on the notion of using internet forums as your source of instructional materials. If it is your plan you should either change it or give up. The choice is yours of course.

Actually it's fairly straightforward.
You start with one. Then comes two. Three. Four. Five.
How far do you need to count?

Hi,
do as below for displaying number of count of click event.
Public Class Form1
Public count As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
count += 1
Me.Label1.Text = count.ToString()
End Sub
End Class

Hi,
We are writing an WPF application using .NET 3.5 with Enterprise Library 4.1. We have created an custom handler - UIExceptionHandler within our exe project. When we try to invoke the ExceptionPolicy.HandleException(e, "UI Message Policy"); method, we encounter the below [1] error.
Find below my code for
namespace CName.DName.AName.UI
{
[ConfigurationElementType(typeof(CustomHandlerData))]
public class UIExceptionHandler : IExceptionHandler
{
public UIExceptionHandler(NameValueCollection ignore)
{
}
public Exception HandleException(Exception exception, Guid handlingInstanceId) {
DialogResult result = this.ShowThreadExceptionDialog(exception);
return exception;
}
private DialogResult ShowThreadExceptionDialog(Exception ex)
{return MessageBox.Show("Some Error Message", "Application Error", MessageBoxButtons.OK, MessageBoxIcon.Stop);
}
}
}
Also find below the implementation of the custom handler in the app.config file
<
add name="UIExceptionPolicy">
<exceptionTypes>
<add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" postHandlingAction="NotifyRethrow" name="Exception">
<exceptionHandlers>
<add logCategory="General" eventId="100" severity="Error" title="Enterprise Library Exception Handling" formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" priority="0" useDefaultLogger="false" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Logging Handler" />
<add type="CName.DName.AName.UI.UIExceptionHandler, CName.DName.AName.UI" name="UI Message Handler"/>
</exceptionHandlers>
</add>
</exceptionTypes>
</add>
FYI - When I tried implementing the UIExceptionHandler custom handler class in an DLL and provided the full name in the app.config, it worked fine. But this fails when I create the handler within the exe project. The name of our exe project is Test.
What might be wrong here?
[1]
The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl, UIExceptionPolicy]) failed: The type 'CName.DName.AName.UI.UIExceptionHandler, CName.DName.AName.UI.' cannot be resolved. Please verify the spelling is correct or that the full type name is provided. (Strategy type ConfiguredObjectStrategy, index 2)

I don't think anybody will be able to answer your question. Try wrapping it around a bit so that it fits on the page.

I got this resolved.
Within the project properties of my exe project the Assembly name was set as Test. So within the UIExceptionHandler class, I had to change the namespace from namespace CName.DName.AName.UI to namespace Test and this resolved the issue

Hi there! I've just released an Alpha 1 of a new .NET database migration toolkit and hope you'll find it interesting.
It's pretty much inspired by Ruby on Rails (namely, ActiveRecord Migrations). Most notable features are: a special DSL for writing migrations
migration "Oxite" revision => 1:
version 20090323103239:
oxite_Language:
LanguageID type => Guid, nullable => false, primary-key => true
LanguageName type => AnsiString, length => 8, nullable => false
LanguageDisplayName type => String, length => 50, nullable => false
index "" columns => [LanguageName, [LanguageDisplayName, desc]]
automatic version tracking, automatic generation of "downgrade" migrations and generally a very seamless experience while dealing with the DB.

A post about this technology is less effective than a fullblown-article; here it might even attract flames, since it's not a programmingquestion.
An article OTOH doesn't have to contain a question, but can also be used to introduce new idea's or frameworks. Plus they're easier to find through Google

You can read from Microsoft msdn site http://msdn.microsoft.com/en-us/library/bb386063.aspx.
if you are migrate your code to VS05 to VS08 then you have face some new problem.
Like : Functions, Methods which have a new name and new definiction.
Best Regard

You will certainly not have any problems with new method names. First, VS-2008 allows you to choose which FrameWork version you want to target. Second, the 3.5 FrameWork is in fact the 2.0 FrameWork plus additional libraries - it is not a new version of the 2.0 libraries.
Perhaps it is possible to have issues when migrating but I've seen none. And that is very much the opposite of what was the case when we migrated from 1.x to 2.0.

Hi，
I'm using COM component(Axis Media Control) in .NET framework with language tool c#.
"Play()" is a member function of Axis Media Control（network camera）. When I use it in WinForm, after I execute the sentence "AMC.play()", it works all right and shows the image.
But When I try to use it in webservice ,using the sentences like "AxisMediaControl AMC = new AxisMediaControl()" and "AMC.play()",after execute the "play()", it doesn't show any thing nor occur errors. I don't why. I wonder if in webservice there doesn't have any place to show the image( not like in winform can add the control in [design] ) , or if i need to offer a place or window to show the image in webservice.
I also want to know the difference between webservice and winform when using the axis media control. Thanks!!

Show it where? A WebService has no display to display anything on.
lynn1007 wrote: I don't why.
Hopefully my first comment clears that up for you, yes?
Also someone developing a WebService that doesn't already know this, indicates they are working on a subject that they don't understand anywhere near well enough to be working on it. I mean rather than developing a WebService you should be reading, studying the subject to understand it clear enough before developing.

Thank you so much.
Your reply does cleat that up for me. But I have some more questions.
"A webservice has no diplay to display anything on" does it mean that I cannot realize the function "play()" of the Axis Media Control(an Activex Control)? Does it also mean that I cannot use the control in webservice for web develop，it can only be developed in website and winform？
I'm trying to use the COM component in webservice, and the problem I encountered really puzzles me. I've been confused for many days.
Any advice is appreciated. Thanks!!

Indeed and I know why, and I spoke to that in my last post. You either didn't read it or chose to ignore it.

You lack understanding very important factors of client/server computing. In some cases these fundamental factors are laws of the universe and must be understood otherwise days of confusion will follow. I strongly urge you to go learn some things about the technology you are working with. If you choose to ignore my advice many more dark days of confusion surely await you.
