• .NET Development sign message SHA256withRSA

  I need to sign message and use the SHA256withRSA  algorithm for hashing. But when call the method rsaSignData of the class RSACryptoServiceProciver it  doesn't work. But the code works with "SHA1". Is there a way to handle this with signature algorithm Hi Freddy, The RSACryptoServiceProvider class actually is a pretty thin wrapper around Windows' crypto implementation (like all of the *CryptoServiceProvider classes are).  When you call SignData, RSACryptoServiceProvider is going to turn around and ask Windows to do the actual signing operation.  However, Windows cannot use managed crypto algorithms, ...Show All

• Visual Studio Tools for Office ClickOnce with VSTO - The application is improperly formatted.

  Hi, I am trying to deploy a VSTO application using ClickOnce. I am getting the following warning in Visual Studio's Error List.

• Windows Forms Can I suppress ValueChanged?

  In my .NET2 (C++) application I have NumericUpDown boxes. I use the ValueChanged event to trigger commands which are then stored in an undo list. When an undo is requested, I query the command for the previous value and place this back into the Value field of the control. Now this then triggers a ValueChanged event which puts a command in the undo list -- not what I want! I can avoid this by setting a flag to say "don't add commands when an event arrives", but I was wondering if there was a better way to reset the value without triggering the event. The undo value is by construction valid since it was retrieved from a validat ...Show All

• .NET Development How to apply changes from DataGridView to DataTable?

I created a new DataGridView control and bound a DataTable on it. The problem is that if I alter data in the DataGrid nothing is changed in the DataTable not even if I call  DataTable.AcceptChanges().
