I am trying to use System.IO.Compression to compress/decompress the buffer. I have the data in byte format in sql server and I need to create an CLR user defined function. I have everything running except that for some of the files, the compressed size is larger than the actual file size. I tried to use both Deflate and GZip compression types. Did anyone face the similar situation. Thanks in advance for your help.
Thanks

If you try to compress a file that is already compressed (like zip, jpg, mp3, mpeg, wmv, etc.) you may end up with a file that is larger than the original, as the file can't be compressed further and the compression adds metadata.

Note: GZip uses the same algorithm as Deflate, so you won't see any noteable differences in file size between them.

Folks;
I have looked at the article By David Broooks, "Dynamically adding ActiveX controls in managed code", but I am still uncertain about how I can replace the VB6 'VBcontrolExtender' functional under VB.NET in order to add OCXes to my application at run time.
I have a few years of code in the OCXes that I am trying to host this way. Each OCX represents an interface to data aqcquisition hardware, and in my current VB6 application, is dynamicallty loaded depending on which piece of hardware the user wishes to connect to.
Without going into too much detail, compiling the application with all of the OCXes in it would force me to distribute an awful lot of code - which is why I was using the VBcontrolExtender under VB6 in the first place.
Following the code example by David Broooks, I can add an OCX to a form at run time, but I do not know how to get 'ObjectEvent' messages from the OCX's that I have added to the form.
I have looked high & low for a solution to this, but I am not yet expert enough in VB.NET to figure this out.

OK I've scoured the WEB for this but can't find a working solution.
I'm trying to create a "fade" effect for a user control without any luck.
Basically I'm trying to get the control to gradually "appear" on a form as part of it's methods, i.e. add the control to a from and then "fade" it in.
As an example, assume I have a user control containing various other controls (text boxes, labels, listviews, etc.). The control should then fade all of these in.
NOte - I can't use a Form and then change the opacity, it has to be a user control, but that's basically the equivalent effect...
Any ideas?
Thanks.

If x = "MinPasswordLength" Then
dom.MinPasswordLength = 10
End If
Next
ErrorHandler:
MsgBox Err.Description
End Sub
Function ComputerName() As String
Dim buffer As String * 512, length As Long
length = Len(buffer)
'GetComputerName returns zero on failure
If GetComputerName(buffer, length) Then
ComputerName = Left$(buffer, length)
End If
End Function
'My computer is connected in domain. if I specify the domain name instead of ComputerName in

.net 2.0 seems to be a little different when saving data back to a database. In the form designer I created a datasource and dragged fields to the textboxes on the form. VB created some objects including a dataadapter an inserted these objects in the form designer tray. When I click on the save button the following code runs but does not update the database. What do I need to do to updata the database? Thanks for anyhelp given!
Me.Validate()
Me.MyTableBindingSource.EndEdit()
Me.MyTableTableAdapter.Update(Me.MyDataSet.MyTable)
Me.MyDataSet.MyTable.AcceptChanges()

If you are using an access database, check if you have created the primary key You cannot update your database until you create the primary key.

I have a class that I want to serialise to XML with a date value as one of the members - however I need it to either (a) populate the xml element or (b) not create the element at all. I have implemented it as a nullable(Of Date) e.g.:-
<XmlType("paydates")> _
Public Class IRSPayDates
#Region "Private members"
Private _StartDate As Nullable(Of Date)
'-- 8< ---------------------------------
#End Region
<XmlElement("startdate", datatype:="date")> _
Public Property Startdate() As Nullable(Of System.DateTime)
Get
Return _StartDate
End Get
Set(ByVal value As Nullable(Of System.DateTime))
_StartDate = value
End Set
End Property
End Class
However, serialising this with an empty date comes out as:
<paydates>
<startdate />
</paydates>
How would I make it omit the null date element at all?

This would be probably due to the fact that Excel Workbook object or Excel Worksheet is left open. You need to close them after using. There is a property I dont remember exactly that will close the object and do the trick for you.

'Close the workbook
xclWorkbook.Close
'Quit Excel
xclApp.Quit

Hi All,
I have a Application which generates XML file and this XML file will be used to generate Crystal Report. Using wizard, i.e. by right clicking and selecting Add/Remove Database on Database Field we can set Data Source into the Report. Now I want to do the same, i.e. setting Data source through code. Can any body tell me how can achieve the same.
Thanks in advance.

Use unicode data types (nvarchar,ntext in SQL Server) to handle multiple languages.
If you want to enter text in one language and search using another language, you may need to use some form of normalization to convert the text to a common format.

In the end we're all just the same
