• shayc How to specify which certificates are trusted when using https for web services

  Hi, I want to use https when consuming a web service created by creating an endpoint with ms sql server 2005 and specify PORTS=SSL when creating the endpoint.

But when trying to consume the web service in my project I got a problem that the certificate is issued by someone whom I don't trust (i am the author of the certificate). Can anyone tell me how to specify which certificates I trust Thanks, Anton You need to add the certificate in your Trusted Root Authority. See http://ww ...Show All

• cisco0407 How to extract enum strings

  Say you have an old-fashioned C/C++ enum like this from a 3rd party public header file: typedef enum { NOERROR = 0, FAULT1, FAULT2 } ErrorType; How can I extract string representations of the enum's members (i.e. "NOERROR", "FAULT1", & "FAULT2") from a clr/.net based application (in C++ or C#) If the enum was defined as a managed 'enum class' then I would be able to call Enum::GetNames() to get the strings, but it's not clear how to create an enum class and associate it with a pre-defined legacy enum like this. Seems like the TypeConverter or EnumConverter classes should help, but I could use some help with the implementation. Thanks. Thanks for the re ...Show All

• robinjam DateTime interpretation between ADO.Net and SQL Server

  In my application I write to a table in a database a DateTime field (which happens to be a primary key) by executing a SQL command, e.g. INSERT INTO MyTable (MyDateCol) VALUES ('8/22/2006 4:20:21 PM'). Then, I insert the same value into another table (in which that same field is a foreign key) by using ADO.Net's SqlAdapter->Update(), where in a DataTable in a DataSet I had stored that same System::DateTime object. I am getting a failure - foreign key constraint violation - when trying to do that last write. When inspecting the value of that field in the DataSet from within the debugger, the date looks like this: "22/8/2006 16:20:21" (same thing, just different representation). This is all on the same computer so the culture is the same ...Show All
