• Windows Forms HyperLink Column in GridView

  I've made the first column of my gridView as Hyperlink Column. The problem is that whenever i click the hyperlink it redirects to a page with the same query string. I need the query strings to be different for each Hyperlink(Eg: I need the id of the clicked row). This is the code i've written Dim bc As BoundField con = New SqlConnection( "server=levergent4;uid=sa;database=octadata" ) con.Open() Dim da As SqlDataAdapter da = New SqlDataAdapter( "select RoleId,RoleName,RoleDescription from Levit_Role" , con) ds = New DataSet da.Fill(ds, "Levit_Role" ) GridView1.DataSource = ds Dim hlb As HyperLinkField hlb = New HyperL ...Show All

  Does the generation of .NET classes from EDM schema and entity relationships uses the actual relational database Also when you create EDM schema and entity sets and relationships, does the database really has to exist Yes, we have plans for upcoming releases. The entity mapping tool (internal prototype I mentioned in another thread ) has a schema translation feature that allows generating a relational schema (.ssdl file) from an EDM schema (.csdl file) and exporting SQL DDL to create the necessary tables in the database.

• Visual C# P/Invoke call to external DLL

Whatever I try to declare as buffer (ref string, out string, ref StringBuilder, out StringBuilder) ends up causing a System.AccessViolationException in .NET 2 (C#, VS 2005). Here is the info I have about this call: Delphi: function DNA_Param(param,value:pChar; value_size:integer):integer; stdcall; VBasic6: Public Function DNA_Param(ByVal param As String, ByRef value As String, ByVal value_size As Integer) As Integer C++: int __stdcall DNA_Param(char *param,char *value,int value_size); Request to the DNA Clie ...Show All
