Hi,
I am not sure what is the question is ... constructors can be declared to create a new object of that class ... they can by public (accessible to outer classes) or private (only to the same class) now its not commonly used to declare a private constructor ... most common case is when you are creating a singleton object (read about singleton design pattern)... but can we use constructors in the same class ? Yes we can ... no roles can forbid doing so ...

Just what use do you suppose a constructor would be if you couldn't access it from outside the class?
Go read a book on C# and/or programming.

In a Factory pattern, you would hide constructors by making them protected or private, then provide a public CreateSomeObject() method that actually invokes the appropriate constructor.

There are plenty of reasons for keeping a constructor private within a class, you just need to know why.
Examples -
0. Singleton or cached class where you want to control the instatiation through a static method. The method is public, the constructor private.
1. You have several public constructors and wish to use one combined super constructor that talkes EVERY parameter, however you don't want to make the super constructor available - again you keep it private.

Look, you've been posting basic questions all over this forum. Here's an idea - rather than running against a problem, posting it here on CP and then potentially waiting hours for somebody to reply; why not actually go out and buy a book that covers the basics? Then everytime you run up against something you don't know the answer to, you've got two choices; 1. read the book; 2. whack yourself around the head with the book until the urge to post a basic question is gone.

Has been suggested many times already, to no avail. Also good replies don't sink in. I stopped reading his posts. And his replies to other posts.

I can recommend you reading about threading in .NET ... hundreds of articles are exist in the Internet, start searching here at the codeproject.

Hi,
The Global Address List (GAL) is an address book derived from Active Directory data maintained by the network administrator on the server.
If you want to access a user's Outlook contacts, use the Namespace.GetDefaultFolder method to return the contacts folder as a MAPIFolder or (in Outlook 2007) Folder object, then iterate that folder's Items or use the Items.Find or Items.Restrict method to filter for specific criteria.
The code below will get the names from the Address book:
string sname1 = objAddressList.Item(20).c.Item(1).Name;

Tell the OP that you have found a possible solution, where you found it, and most importantly give the link.

Just wanted to ask you to please put a break;in this loop? anywhere is the right place!
while(1 != 0)
{
ask 'how can i set the text of a textbox programmatically'
questions;
post 'Hi, this is MY answer (that i found on some site) of
YOUR question!' replies;
ask people for the code for this (the text of a textbox),
since you think the code you have (found in some other website)
works only for ASP.net.
}

Hi,
I am working on a project where I have used a ListView to add and clear items. However, due to frequent adding and deleting, the ListView is being hard to maintain. So I thought of binding items to the ListView. Since it is not possible to bind an object to a ListView straight away, I was advised to use a GridView in a ListView and bind items to the GridView. I googled it to some extent, but I couldn't find an apt match. Can anyone post a link which might explain me what to do to use a bound GridView in a ListView? I'm using WinForms, not WPF...
Thanks in Advance,

A quick Google for "bindable ListView" came up with an article here on CP[^], along with a bunch of others all over the web.

Hi Dave,
Thanks a lot for your reply.. I have already analyzed the example project that you had posted a link to.. It doesn't suit my requirement because the example loops through a table and updates the ListView. That is exactly what I'm doing right now, just that I do not use a table but I iterate using a list of objects. But my case is that I add a huge number of items to the ListView at a moment, probably in the range of a few 1000's. That time, the performance of the ListView is not very pleasing. So, a pure DataBinding concept, as in the case of a DataGridView would be really helpful. I was told that a GridView in a ListView might serve this cause. Any opinions on this would be really helpful.
Thanks in Advance,
ramz_g

AFAIK it would be enormously difficult to put a gridview in a listview.
Why not simply use a DataGridView?

Hi Henry,
Thanks for your reply. Using the DataGridView was always one the options that I had. Maybe its time that I zeroed-in on using the DataGridView...

hello
is it possible to bakcup a database at a server and restore it at an otehr one?
if yes,thanks to give me some ideas
|
|
|
|
|
Yes - assuming SQL Server
Backup to a file using management studio
copy file to different server
restore database using management studio
Depending on the database/version you may need to create the database before you can restore into it.
