I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]

I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.

I have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
I then make a debug button to check this
Variables:
Dim DebugInt As Integer = 0
Dim bs As New BindingSource
[Code].....

I am trying to make a GET request to a .php page. To get to this page I have to pass before to a login page (username and password then).My application has a browser from where I manually login and then with one button I want to do this GET request but not from the browser. I need to create a GET request using the cookie and Session ID from the browser in my app.I think I need to create this GET with the original header from the browser but I am new to vb and I am trying to figure out how:
1. create a simple GET request
2. add cookie, session ID, headers to the GET request
3. get the page source (I already use the browser.document but I'd like to retrieve it from the get request).

I�m using VB.Net 2008 application program.I�m using DataGridView. I have a Print option where i need to print the DataGridView. I�m using this code for Printing and for Print Preview.
Code:
Dim MyDataGridViewPrinter As DataGridViewPrinter
Private Function SetupThePrinting() As Boolean
Dim MyPrintDialog As PrintDialog = New PrintDialog()
[code]....
Attached the class i'm using for print.I have 10 fields showing in datagridview. As the last 5 columns header is long, the datagridview is not fitting inside 1 page (not showing all 10 fields in one single page). But is there a way i can "Text Wrap" the top header column and lock in the width, then it should print across one page perfectly.If you know how i can "Text Wrap" the top header column and lock in the width to print across one page?

I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)
[Code]...
I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!

I have a question thats been bugging me for quite some time now.Recently, I've created a ButtonRow control which is meant to host several buttons on its surface. These buttons are added through a collection property using the property grid of the VS IDE. The property is tagged with the DesignerSerializationVisibility(DesignerSerializationVisibility.Content attribute.The objects in this collection are serialized to the designer code of the form or usercontrol on which the ButtonRow is placed. Now it all works fine and everything except that I cannot implement a Name property. I'll explain what I mean by this.
If you've ever used the DataGridView control, you'd notice that the columns work in the same way that buttons work for my control ie a serialized collection. However, the DataGridViewColumn has a Name property which can is used as the variable name when the column is serialized into designer code.
Example: If you place a DataGridView on a form and add a column and change its Name to lets say "AGreatColumn" then the designer would serialize the column as such:-
[Code]...
I went as far as using .Net reflector to decompile MS source code to see how they may have achieved this but I could not find the secret. Also notice that the designer serializes my objects using a Dim statement but the DataGridViewColumn uses a Friend Withevents declaration at the bottom of the designer code file(I didnt it included above)

Is there a way for implementers of an interface where a ReadOnly property is defined to make it a complete Read/Write Property ?
Imagine I define an interface to provide a ReadOnly Property (i.e., just a getter for a given value) :
Interface SomeInterface
'the interface only say that implementers must provide a value for reading
ReadOnly Property PublicProperty As String
End Interface
This means implementers must commit to providing a value. But I would like a given implementer to also allow setting that value. In my head, this would mean providing the Property's setter as part of the implementation, doing something like this :
Public Property PublicProperty As String Implements SomeInterface.PublicProperty
Get
Return _myProperty

I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

blue.Red = 0
blue.Green = 0

The error I receive on this line ("vision.Widgets.CreateWidget(wg1)") reads "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."

I have a very simple class that holds a few public properties - ID, Text, Colour, etc. and a Boolean called 'SelectedItem'. Just like the Checked property on RadioButtons, only one item can have its SelectedItem property set to True within a particular group. Note: there will be several separate groups (lists), each allowed to have only one item with SelectedItem = True.
My first thought was that I would probably just have to handle everything outside of the class, setting SelectedItem to False for every other item in a particular list when another item was selected. But that seems rather inelegant to me. So I've been trying to think of how this might be done within the class. For example: could I perhaps have a private string property called say "GroupName" - set in the New sub when adding a new instance of the class - and then use a private shared method to set every item's SelectedItem property to False, provided the item has the same GroupName as the newly selected item? I would have a go at doing this but I have no idea how to enumerate every instance of a class from within that class, or whether that's even possible. Is it? Or is there another (better) way to achieve my goal? Here is a cut-down version of what I've got so far:
Public Class ResourceItem
Public ID As Integer
Public Text As String[code]....
As can be seen: instead of instantiating a new ResourceItem and passing that as an argument to the manager's Add procedure, I'm simply passing the details of the new item and the procedure is creating the item from those. I don't know whether this is a good or bad idea - please advise - but I've done it because I couldn't figure out how to make the SelectedItem property only writeable by the manager, so I wanted to avoid having directly accessible objects that could have their SelectedItem property set to True without it deselecting all the other items in the same group. Of course that still leaves the possibility of setting a variable to one of the manager's list items and setting it from there, so I would still like to know how I could prevent that, if possible.
UPDATE: I didn't use the code above in the end, deciding instead to go with Cyborgx37's solution - which seems to work perfectly well for me despite the warnings about best practice. I also realised I would need to use the same class in another scenario where multiple items could be selected, so it was easy to add a Boolean property to the manager to enable that.
