You don't. XML is not meant to be used as a database and has poor performance when used as such.
XML also doesn't understand SQL commands.

You use it just like any other COM object. All a reference to the file the object is exposed in and create a new instance of it:
Dim myObj As New MyComClass

hello im new here and i was wondering if any of you can help me with my small problem. is it possible to create an array of subprocedures? because il be decoding a binary string and those with 1's will call a specific procedure so il be using an array of subprocedures.. anyone have a sample code? tnx
FUNGAS!

There's no such thing as an array of "subprocedures". But, you can create an array of delegates. This example uses three subs that all take a single string as a parameter. You can NOT use a single delegate to point at subs with different argument lists.
Private Delegate Sub TestDelegate(ByVal str As String)
Private Function CreateDelegateList() As List(Of TestDelegate)
Dim d As New List(Of TestDelegate)
d.Add(New TestDelegate(AddressOf TestMethod1))
d.Add(New TestDelegate(AddressOf TestMethod2))
d.Add(New TestDelegate(AddressOf TestMethod3))
Return d
End Function
Private Sub TestMethod1(ByVal paramValue As String)
' Do something useful...
End Sub
Private Sub TestMethod2(ByVal paramValue As String)
' Do something useful...
End Sub
Private Sub TestMethod3(ByVal paramValue As String)
' Do something useful...
End Sub

so if i use something like createdelegatelist(1) then il be calling testmethod1?
or i use d.item(index)?
FUNGAS!

Notice that CreateDelegateList doesn't take a parameter?? So why would you pass one into it? CreateDelegateList just builds the list and returns it. It doesn't execute anything.
wuzzywezzer wrote: or i use d.item(index)?
You'd create a List(Of) to hold the list returned by CreateDelegateList, then use an index to Invoke the method the delegate points to:
Dim dl As List(Of TestDelegate) = CreateDelegateList()
dl(0).Invoke("This is a test string being passed to the TestMethod.")

The second lacks a space between the i and comma. The second also contains a spelling mistake.

I don't see any differences!
In vb6 the first statement resulted in declaration of i As Variant and j as integer.
But in VB.NET both declarations are the same!

yah what u said is correct.
|
|

MohammadAmiry wrote: ..i As Variant and...
dim i ,j as integer ' i thought this declares both i & j as integer.
thanks again
|
|
|
|
|
both are one and the same thing what u suitable u can do it
if u write single line then this is smart work
|
|
|
|
|
in vb 6
-------
Dim a(10), k, j As Integer 'this will not work
'but thi will
Dim a(10) as integer
dim k, j As Integer
'input values 1-10
'-------------------
For j = 1 To 10
a(j) = InputBox("Enter a number")
Next
k = a(1)
For j = 1 To 9
If k < a(j + 1) Then
k = a(j + 1)
End If
Next
MsgBox k
thats why ask about it !!!
thanks for response

Hi,
People must be aware of the pivot table available in Excel.
I would like to create a pivot table in Vb.Net and allow the user to drag and drop the fields required for the report. (or atleast select the fields from a list), allow drill down, sorting, totalling, sub totalling etc
Is there any ActiveX or OCX control available to do this?
Any help would be of great appreciation.

Yes there is. One is infragistics>>NetAdvantage>>UltraGrid Control.
It does all you want plus lots of other benefits. Try the trial

This is way too much code to post. Ambiguous usually means that the name is defined more than once in the same scope in your code.
