Hi,
does anybody know, how to convert RSA public key into Base64 Encoded string.
Actually I'm creating Keypair and digital signature using RSA in VB.NET and verifying it into java. For that i need to store the the RSA public key into a file on the hard drive. Later Java class will fetch this public key and use it for verification.
But when i give the RSA public key into Xml format to Java class it is giving an error "Invalid Key Exception." Java class needs Base64 encoded string. So how to convert this xml key into Base64. It will be gr8 if anybody helps me in this issue.
thanks

How to preview Report without using crystal reports and Export it to any format like Pdf,xls etc.

That would depend on what kind of report you're using. If it's a Crystal Report file, then you need use crystal reports. If you haven't created the report yet, then I would look into a 3rd party add-in that will allow you to do that. If you only want to display it in one format like excel, then you can just create an Excel Application object and fill your sheets through it.

Hiya, Do you mean how to preview your crystal report classes? I had the same problem. I was browsing the net looking for an answer when I found a web site that offered a means to do just that. Below is the link
http://www.itteam.net/itteamreportviewer.html[^]
They offer a number of low cost .Net development utilities.
Hope this helps

I am trying to connect to a system in a network through WMI.
If i am not able to connect to a system through WMI then generally i get
"Access Denied" error. for which i know the solution.
But now i am getting "RPC server unavaliable"
Can someone tell me shat does it means and it's solution.
|
|
|
|
|
sounds like the rpc server isn't running on the machine you're attempting to connect to. Pull up the services on that machine and see if it's running.
|
|
|
|
|
We have checked the services and yes they were stopped but even after starting it we are still getting the same error.

You can pass the parameters into a hashtable. And then create a loop to pass these parameters one by one to it. You can use following example:
Public Function SelectEmployee(ByVal OracleConn As String, ByVal SPName As String, ByVal crOutput As String, Optional ByVal ParamTable As Hashtable = Nothing) As DataSet
Dim m_objDA As New OracleDataAdapter
Dim m_objDS As New DataSet
Dim m_objDBCmd As OracleCommand
Dim m_objDE As IDictionaryEnumerator
Dim Conn As New OracleConnection(OracleConn)
Try
m_objDBCmd = New OracleCommand
m_objDBCmd.Connection = Conn
m_objDBCmd.CommandType = CommandType.StoredProcedure
m_objDBCmd.CommandText = SPName
If Not IsNothing(ParamTable) Then
m_objDE = ParamTable.GetEnumerator
While m_objDE.MoveNext
m_objDBCmd.Parameters.Add(m_objDE.Key, m_objDE.Value)
End While
End If
m_objDBCmd.Parameters.Add(crOutput, OracleType.Cursor).Direction = ParameterDirection.Output
m_objDA.SelectCommand = m_objDBCmd
m_objDA.Fill(m_objDS)
Catch ex As Exception
'm_objDS = Nothing
Throw ex
Finally
m_objDBCmd = Nothing
m_objDA = Nothing
End Try
Return m_objDS
End Function

Well Require property is just another form of NOT NULL. If you don't specify NOT NULL it will take NULL values I guess.

You need to Sleep in between.

i think i get you.
you want to give some milliseconds to the free-time thread that counts the left time of CPU.Therefore CPU use will not be 100%.
Thank you for your bright idea.
I evalue the data (read from equipment) to form control (textbox).As below:
textbox1.text=str.tostring.trim 'str is the data
If i alter it to: console.writeline(str.tostring.trim)
The cpu use will reduce to 1% more or less.
How could i transfer the data to a form control without hige cpu usage?
Maybe we could be mailfriends.
Contact me by MSN as below
Regards.

I don't know what you are saying. I have never experienced this. How could CPU usage go up when you are updating the value of a control.
Just a min, what is the size of str. Is it too big a string. Edit controls only take a max of 64KB. ( ) So if the string size is more that this then frequent updations could lead to 100% CPU usage.
