View 3 RepliesI need to have some of my columns in an integer value not string.So from I can tell so far and I am extremely limited, if I use WriteXml this should write the schema and the data and the readxml will read the schema and the data, although I dont see the schema in my xml file that gets created from my oDS.WriteXml/if I use oDs.WriteSchema I can view the schema file that is created. Thats how I determined the schema is creating all string vlaues for each column..All the fields are of String value as was pointed out, so how do i create my own schema file? or rewrite the one that is created.[code]

View 2 RepliesI am developing an IT Asset Tracking application using VB 2005 and SQL Server 2005 Express edition. Will I need to create classes to represent objects such as Computers, Printers, Scanners/Faxes, Contracts, Purchase Orders etc or are there any other approaches.For example, if I am correct, I will have a class called Computer and its properties will include Make,Model,CPU,Hard Disk,Memory etc. Is this the right approach.
Computers can be split up into Desktop PC's, Servers and Notebooks. Would I have to create separate classes for these as well or would they be ok under the Computer class.Once I create an object from the class, how can I use the object to interact with the SQL db.I am a beginner to VB.NET 2005 therefore I am slowly getting to grips with OOP.
I want to create a class is it where I can do...

I want to allow my user to add certain small pictures into a form which has a bigger pictures. My idea is to simply allow the user to move small pictureboxes that is set on the top of the form to wherever she wants it to be. My problem is that she may want more than one instance of the same picturebox. I am wondering if I can create a picturebox (complete with the picture) during run time?
View 2 RepliesWhat would be the best approach to create the following: A groupbox that contains several labels a groupbox with an array of 8 labels in it
Then the main form would have 4 of these groupboxs (object?) and I would need the ability to change the color and text of all the various labels within any of the groupboxes, using an index similar to what we could do with control arrays in VB6.
I would think an object would make the most sense but can you have control elements in an object and display them on the form?

View 3 RepliesI'm trying to build a language dictionary in VB NET in order to be able to have several languages in the application.This dictionary has a init method that loads from database the entire dictionary and stores it in memory.In the rest of the classes of the project, I added the reference and I can use directly the object without create a new instance because their methods are shared.
how i have to load the dictionary content in order that the rest of classes only accessing to Language.GetWord method obtains the properly record of the collection, same way as My.Settings class.When My.Settings is used from any class the values are loaded. I'm looking for the same effect.This is the code of the class:
Public Class LanguageProvider
Private Shared CurrentLanguage As Collection
Public Shared ReadOnly Property GetWord(ByVal Label As String)
[code]....
Function LoadLanguage must be called when the application loads, in order to access once to database. After that property GetWord must access to the collection with the words and return the result. The problem is that the instances are not the same and the dictionary is not loaded when a class uses it.
