Can someone help me with the following:
1- I have xml text data that i need to take out invalid characters from.
2- this data contains extraneous characters that i need removed in order to use xmlDocument.LoadXml(str)
3- when this characters are in the str variable i get an XmlException that indicates that there's an invalid character with hex value of 0x0B.
4- how can i remove that character from the string prior to loading it in with xmlDocument.LoadXml(str)?
5- i am using VS2005
Your help is greatly appreciated....

The string class has a replace method, you would generally call that to remove anything you didn't want in there.

1- I see.
2- I see.
3- I see.
4- You can use the Replace method of the string class.
5- Good for you.

Below is the solution I was able to come up with...
Public Structure HexReplacement
Public HexCharacter As Char
Public Replacement As String
End Structure
Public Shared Function ConvertHexToChar(ByVal hexValue As String) As Char
Dim convertedChar As Char = Nothing
Try
convertedChar = Chr(Int32.Parse(hexValue, Globalization.NumberStyles.HexNumber))
Catch ex As FormatException
' Error handling here....
Catch ex As ArgumentException
' Error handling here....
End Try
Return convertedChar
End Function
Public Function CleanOutHexValues(ByVal dirtyString As String, ByVal hexReplacements As HexReplacement()) As String
Dim cleanString As String = dirtyString
For Each hr As HexReplacement In hexReplacements
cleanString = cleanString.Replace(hr.HexCharacter, hr.Replacement)
Next
Return cleanString
End Function
Public Sub TestHexCharCleanUp()
Dim hr(1) As HexReplacement
hr(0).HexCharacter = ConvertHexToChar("0b") ' "0b" = or single space.
hr(0).Replacement = ""
Dim dirtyString As String = "Testing the removal of "
MsgBox(CleanOutHexValues(dirtyString, hr))
End Sub
Comments will be greatly appreciated.

Been playing around with the progressbar, just trying to figure it out. Got it running for the most part but here's where it gets weird.
On my laptop I changed the ForeColor to red and it ran in red. When I port the same project over to my main machine & run it, the progressbar forecolor is not red it's the default green color. I checked my properties & it's still showing red as my forecolor. I tried changing it in code, same thing. Both my laptop are main machine are running XP Pro w/SP2 installed. This is VS 2005 .Net btw.
Any ideas, thoughts on why this won't change colors when I run it?
Thanks!

I have had this problem before when working with a progress bar, but my program also changed the buttons. In my case it was the theme that I had set on the computer overrode the setting that I had in VB. This may not be the case in your situation but it is worth a try to change the theme on your computer and see if this changes the progress bar in your app. If this is the case I am not exactly sure how you can fix it but there is a setting in VB under Project and properties on the application tab where you can check "Enable XP visual styles". Unchecking this may fix the prob.

That was it! Thanks much! I switched to a Windows Classic theme & ran it. Ran perfect. Then used your suggestion of making the change under my IDE. That too fixed my issue. 
Thanks again for your advice!

Wonder if anybody can point me in the right direction? I'm wondering what I'm doing wrong.
I have a parent and child form. On the parent form, I have a CustomerID field - which is a CustomerID field in my tblCustomersParent table my Access database. I have a similar field in tblCustomersChild to create the relationship, and a field on the child form to display it.
This CustomerID field is passed to the child form using:
Me.frmCustomerContacts = New CustomerContacts<br />
frmCustomerContacts.ValueFromParent = Me.CustomerID.Text<br />
frmCustomerContacts.ShowDialog()
The customer ID is then copied to the child form using:
Public WriteOnly Property ValueFromParent() As String<br />
Set(ByVal Value as String)<br />
Me.CustomerID.Text = Value<br />
End Set<br />
End Property
This works well except for when tblCustomersChild does not have an existing entry for that CustomerID. For example, if I create a new customer (or even if I have an existing customer entry in tblCustomersParent), and then wish to add contacts for that customer, the CustomerID field on the child form does not get populated because tblCustomersChild does not have any corresponding entries already recorded. I can enter a record in Access to make it work, and it does carry that CustomerID through from parent to child, and I can add new contact records to the child form.
I am using a standard SELECT statement to collect the data for the child form based on what the CustomerID field is on the parent form.
I'm using VB.NET 2003.

Try declaring the id variable as public so the child form can access it.

Why not just pass in the value to the constructor of the form:
Me.frmCustomerContacts = New CustomerContacts(Me.CustomerID.Text)
On the chidl form, have a read-only property:
Private _customerID As String
Public ReadOnly Property CustomerID as String
Get
Return _customerID
End Get
End Property
Modify the constructor of the child form:
Public Sub New(ByVal CustomerID As String)
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
_customerID = CustomerID
End Sub

You can do some searches with google and work out how to form a google URL. To put images back out will be a little more complex.

I am selecting and inserting large amounts of data into a SQL database and I would like to inform the user of the progress. How do i do this using a progress bar or something similar.
|

Do you have some kind of looping structure for selecting and inserting records?
How do you do it?
When I know, it will be easier to explain how you would implement the progressbar.

I am selecting and inserting arge amounts of data into a SQL database. In terms of the inserting i have a solution i think i can work with. I will simply get the count of the number or records in the dataset and set the progress bar max value to this. I will then increment the progress bar counter each time a record is added.
The problem is liking the progress bar to the selection process. When I am retrieveing these thousands of records from the databse I wamt to inform the user what percentage of records have been retrieved so far. Is there any way to know what percentage of records have been retrieved so far.

Well, if you know the total of records in the first place, just divide this by 100. The you could do something like this:
Value = CInt(TotalRecords/100) 'Equals 1%
Add a handler for the RowChanged event of your table(s).
Then in the RowChanged events:
Check for: e.Row.RowState = DataRowState.Added
and update a public counter...
Check it against 'Value' and update the ProgressBar.Value when it meets the criteria you choose.
Just one way to do it. It is going to slow down your inserts to some degree though...

In order to do this, you would need to do lots of little inserts, instead of one big one. This will slow down the overall process considerably. If you're stuck with doing it this way, then implimenting a progress bar is trivial. If you're not, I can't see a way to do it without slowing things down.

How do I track the amount of records recieved so far by a select statement?

This line fills my table fine:
Me.TradesTableAdapter2.Fill(Me.DataSet1.TRADES)
This line does not, even though its query is the same as that above, from the same table (Dataset1.TRADES) and the query loads properly in its preview.
Me.TradesTableAdapter2.FillByTodayOnly()
