I am working on a inventory application and I have a question, I have created a table for each of the main categories that I will be using, now if I wanted to add sub categories would I create another table for the sub directory and set the type as a child for its corresponding category or would it be easier to keep the main categories and just add another column in each table for "sub category" so it uses the same table but I can just filter it out easier?
If it is a better option for creating parent and child tables, how would I go about listing them in a hierarchical treeview to show parent and child sub-categories in them.

I want to know what's the right way to work with objects that belong to a category.I'm building an applications with the following layers:Base data access Data access Business logic + Factories Presentation.I want to pass only objects to the presentation layer and back.I have objects (Employees), that belong to a certain category (EmployeeCat). I was wondering if I should have just an EmployeeCatID property in my Employee class/object, or an EmployeeCat property that contains a complete category object.If I want to fill a GridView with a list of employee objects as datasource, and I used just an ID in my Employee objects, then I will have some work at the presentation level to display the category names, so I think. On the other hand, if the list of employees contains plain category objects... I'm not sure what will happen.

I can not use Inheritance Picker Dialog windows. Choosing Project in menu bar and then Add New Item, there is Templates frame only and Inherited Form is missing. Categories frame, which should be located on the left side, is missing as well. So i could not choose Windows Forms from Categories Frame on the left and Inherited Form from Templates on the right. Is it possible that Express Edition does not support Inheritance?

Here's the program. there are five categories say a, b, c, d, e, each in a textbox (color blue). There will be a command button say "choose". If i click the choose button, it will randomly choose one category and that corresponding textbox example "a" will change color(color yellow). Then if I want to click the choose button again, the selected category "a" from the first selection will change to gray, then a new category will be randomly chosen without "a" in the list and again will change to color yellow. and so on. So I can click the choose button five times, exhausting the five categories without repeating the category that was already selected.

I have a project that works with a database. It groups al my films per category. I use this code to group everything by category. The categories are chosen in the combobox cboCateogorie.
category
Private Sub cboCategorie_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboCategorie.SelectedIndexChanged
If Not cboCategorie.SelectedValue Is Nothing Then

what I want is the opposite off what I do when I select a category in a combobox. Now I actually select a film and this film also has an ID, namely DvdID and with that I want that the combobox shows the category where the film belongs to.

I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.

I'm working on the exercise page 73 (VB 2010 in 24 hours). It's basically a form with 2 text boxes, 2 text labels and a command button. It's really simple and uses this loop to cycle through the items, and tell me the name of them in a Messagebox

I need to create kind of a menu in my application in wich I have to set different parameters before I populate a Datagridview with some values.So, the idea is to use a PropertyGris in which from which I can edit some parameters and after that I run a query (with parameters setted by PropertyGrid) tu populate my DGV.For example I create some properties like NAME OF A PROJECT, ID OF PROJECT, RESPONSABLE, etc and I put this properties in a propertyGrid and than the user can interact with the propertyGrid and set value for each parameter, bfore running the query for populating

2/ i need a way to make either selected properties or preferably entire categories disabled or enabled at runtime.
3/ how can i turn off automatic sorting so my categories + the items they contain are displayed in the order they are in my class?

I want to add a new PropertyGrid control every time an item is added to a ListBox.I have a ListBox, with an "Add Item" button underneath (and also a "Remove Item" button). Every time an item is added to the list, I want to create a new PropertyGrid corresponding to each item. The relevent PropertyGrid should appear when an item is selected in the ListBox, and the user can edit the properties of that item.
The only way I can think of doing this is by creating a dynamic array which has length ListBox1.items.count, but I'm not sure it's possible to create an array of controls.

PropertyGrid is only scrollig correctly when I place it on a Windows Form, but does not work when it's docked in a SplitContainer Panel. Only the vertical scroll bar is needed for my application. The vertical scroll bar displays correcly and you can move it up and down okay, but the contents of the PropertyGrid (while correct) do not scroll up and down with it. I'm using Visual Studio 2005 Professional Version 8 with .NET Framework 2.0 and coding in Visual Basic. Has anyone found a way around this?

Using <System.ComponentModel.TypeConverter(GetType(System.ComponentModel.ExpandableObjectConverter))> _
on the declaration of a class (which is a property of another class) that consists of a number properties.
I load an instance of this class with simply ...
PropertyGrid1.SelectedObject = oColumn
Obviously I don't want to manually build the propertygrid in code, I know how to do that.
But here's the problem. Depending on the value of a property, certain other properties should not be visible, as though I'd used the <System.ComponentModel.Browsable(False)> _
attribute on the property declaration.Is there anyway to do this programmatically, without having to handle all the building of the property grid manually>

I'm trying to add a custom DropDown to the PropertyGrid for a control. I am adding the TrackBar control.It works fine, except, I would like to have the values updated in the PropertyGrid as I move the TrackBar. As it is now, it only updates the PropertyGrid when I finish and click off the TrackBar.I know the problem lies in the Type Editor. How can I get it to allow interim values to be processed. Is there some callback function I can use?

I am having a problem with objects that have other objects as properties on a property grid. Now when I display the object clsPropsFrame on the property grid, everything shows up as expected, except when I try to edit the x, y, or z of location which is of type clsPropsVec3, it ignores the change. What's strange is that when I type the vector in as a string (like "0, 16, 0"), it changes.
I have the following
'//////////////////Object Component///////////////////////////
<TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class clsPropsVec3
Inherits ExpandableObjectConverter
Private refvec As TV_3DVECTOR
Public Sub New()
[Code] .....
I noticed that when I changed a component of clsPropsVec3, the property change in clsPropsFrame does not get executed. I tried making it fire of an event when a component is changed in clsPropsVec3, with the following additional
Public Property X() As Single
Get
Return refvec.x
End Get
Set(ByVal value As Single)
[Code] .....
But for some reason it ever fires off the ValueChanged event. So how can I make the sub properties of clsPropsVec3 work?

Within my PropertyGrid I have decorated a class with the following attributes:
Code:
[Category("Category 1"),
DisplayName("Part Number"),
SortOrderAttribute(1)]
Dim PN1 as String
[Code]...
The problem is that when PN2 is changed in the PropertyGrid, it causes a refresh of all cells. Since both properties have the same DisplayName, but different Categories, the focus is set to PN1 and not PN2 after PN2 is edited.

I've been following this article:and have everything working.Under the Support for Custom Types section, it introduces a collapsable type for the spell check options. The option are added together to produce a string that is displayed in the grid in the Spell Check Options row. Is it possible to get this string directly from the 'AppSettings' class or do I need to add another property and copy the code from the ConvertTo and ConvertFrom functions?
