Dear Dave Kreskowiak,
Really i am happy to read your reply, but can you list the content topics in a sequence such that it will help me to cover it very short duration. I mean from which topic i should start and keep my self move ahead, in such a way it create less confusion for for me.
Can you please suggest me some website for it and can you send me some sample application with code and explanation. Just start from much basic application based on ERP. My E-mailId is amitteshwar@gmail.com
Thanks

Yeah, right. You don't get it. ERP systems covers such a huge range of disciplines, applications and systems, that there is no list! You're NOT going to learn how to design enterprise systems in a couple of weeks. This takes years of experience developing all kinds of systems or all different sizes.
Member 8824417 wrote: Can you please suggest me some website for it
There is no one website. There is no one books. ERP systems are about the largest, most complex computer systems you can come by in an enterprise, spanning an entire enterprise, usually touching every corner of the business processes in a company. These systems are not just one application. They are suites of applications, spanning a large range of technologies and languages.
In other words, there's no such thing as an "example" ERP system. There is no such thing as a "simple" explanation for one of these systems.
...and the only people who will every send you an email are the spam bots that troll websites looking for newbies like you who are dumb enough to post your email address in a public forum.

Hello,
I am trying to implement DataLogic OPOS driver. In this dll I have function to connect to device:
int OpenService(string DeviceClass, string DeviceName, object pIDispatch);
Unfortunately vendor documentation is miserable. Can you help me with this last parameter. What is this? If I understand it correctlly it is an instance of class which will react when device will scan data.

What on earth makes you assume that we will know more than the manufacturer?
You should talk to the people who created it - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!
If you don't tell them that their "documentation is miserable" how do you expect them to improve it?
The only instant messaging I do involves my middle finger.

Hello,
I'm writing a class(MyClass) that have a subclass(Item) and a property of List of that subclass(List<item>).
MyClass have a property with name "CurrentItem" that returns required Item.
My class is like this:
public class MyClass
{
private DataTable _mainDataTable;
private List<Item> _items;
public class Item
{
public Item()
{
}
public int Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public bool Enabled { get; set; }
}
private MyClass()
{
}
public DataTable MainDataTable
{
get
{
if (_mainDataTable == null && _items != null)
_mainDataTable = _items.ConvertToDataTable<Item>();
return _mainDataTable;
}
set { _mainDataTable = value; }
}
public List<Item> Items
{
get
{
if (_items == null && _mainDataTable != null)
{
_items = _mainDataTable.ConvertToListOfItems<Item>();
}
return _items;
}
set { _items = value; }
}
public int CurrentItemIndex { get; set; }
public Item CurrentItem
{
get
{
if (Items == null || Items.Count == 0 || CurrentItemIndex + 1 > Items.Count)
return new Item();
return Items[CurrentItemIndex];
}
}
}
And this code is an example of using it:
Myclass obj=new Myclass();
int id=obj.CurrentItem.Id;
My problem is: I don't know that is there any way to access properties of CurrentItem directly without writing CurrentItem. like this code:
Myclass obj=new Myclass();
int id=obj.Id;
Is there any way to do this?
Thanks

Create a property called "Id" in MyClass and have it return the Id of the CurrentItem object?

Several things in your code "jump out at me" as kind of ... confusing:
1. you made the constructor of MyClass private: so you cannot create a new instance of MyClass. Since MyClass is not a static class, the dance will never begin.
2. so, changing the access modifier to MyClass' ctor to 'public, and creating a new instance of 'MyClass:
a. you have not created any instances of the Item class simply by creating an instance of 'MyClass ... there's nothing inherently wrong with that.
b. the Items collection in _items will be null ... nothing wrong with that.
3. MyClass does have a 'CurrentItem property which will contain null when instances of MyClass are created.
a. but when you access 'CurrentItem, which only implements a 'get: if your internal List<Item> is null: it will create a new Item and return it, but none of that instance of Item Class has its internal fields initialized.
4. the only other means by which I see in your code creates instances of the 'Item class is provided by code you do not show in your question here, via a call to what looks like an extension method on the DataTable Object: _items = _mainDataTable.ConvertToListOfItems<Item>
Since multiple instances of the 'Item class are, obviously going to be created: with the way you have your code structured now, you can only access the Properties of the last created instance of 'Item via the 'CurrentItem property, or by selecting an instance of 'Item in your List<Item> stored in _items.
So to answer your question, specifically, yes, you can execute int id=obj.CurrentItem.Id; as you show, just after you create an instance of 'MyClass (if you change the ctor to 'public), and id will be set to #0, because your invocation of 'CurrentItem caused a new instance of 'Item to be created, and an integer variable will have a default value of #0 when an instance of a class is created.
Big picture: it looks to me like your code needs some strategic re-thinking, about which I can't comment since I don't understand your exact goals here.
As the code is now (once the ctor of 'MyClass is set to public access) I can create an instance of the 'Item class without creating an instance of 'MyClass: do you really want to allow that to happen ?

Well Google[^] has many, many working solutions. The very first[^] one looks promising.
|
|
|
|
|
I did go through the google, but it was very confusing for me since I am very new to c#. I am not familiar with linq or xmldocument or....so couldnt exactly makeout which approach to take.
|
|
|
|

You actually need to try out some of this stuff for yourself though. If you see a result, look at it and try it out. Then you'll know if it fits your needs or not. And if you're new to C#, you might want to buy some basic books on it.

How much time did you waste waiting for someone here to come along with the answer though? Bear in mind that, as volunteers, we answer questions when we can, so you could have waited hours before you got any answer.

I did try lot of things before i posted question here. what i meant was I wish i had time to go through the books now.

Can´t run before you walk.
XML can become pretty complex very soon so time or no time, my advice would be to complete a tutorial (a book, no website) reading, including excercises before diving into this.
C# and XML, I would recommend LINQ (to XML), but before diving into LINQ you need a thorough knowledge of .NET.

Different approach from Pete's answer is to use XMLSerializer deserialize[^]
Google has many examples that you could work from.

If you are totally new to programming as well then you might want to give up.
If you however experience in the SQL of your database then it is likely you can solve it using only that and much faster than learning enough C# to meet your "urgent" need.

If you use Linq To XML, you can do 90% of the processing with a single class: XElement. Linq To XML is elegant, and gives you (for example) IEnumerable lists you can process with foreach. It's my first choice for parsing XML.

The Picturebox I believe.
PictureBox pictureBox1 = new PictureBo();
pictureBox1.Image = System.Drawing.Image.FromFile(@"");
With great code, comes great complexity, so keep it simple stupid...

Well, to handle the image management and display, I'd use the techniques I wrote about in this[^] article.

Well, you haven't really explained what the problem is, apart from implying that you need an IBM addin. However, you may find http://www.connectionstrings.com/[^] a good place to look for some suggestions.
