I would like to automate script generation (in SSMS --> Tasks --> Generate Scripts) in SSMS 2008. I have read that SQL Server 2008 does not support Database Publishing Wizard (including SQLPUBWIZ SCRIPT) but this automation can be done using SMO in SQL Server 2008. I don't have a clue about SMO and how to do this using SMO, so could you give me some advice (resources etc.) how to begin?
The key to SMO scripting is the Scripter class. All other tools (like SSMS) use this class to generated object creation scripts. There is an example usage on MSDN:
{
//Connect to the local, default instance of SQL Server.
Server srv = new Server();
//Reference the AdventureWorks2008R2 database.
Database db = srv.Databases["AdventureWorks2008R2"];
//Define a Scripter object and set the required scripting options.
Scripter scrp = new Scripter(srv);
scrp.Options.ScriptDrops = false;
scrp.Options.WithDependencies = true;
//Iterate through the tables in database and script each one. Display the script.
//Note that the StringCollection type needs the System.Collections.Specialized namespace to be included.
Microsoft.SqlServer.Management.Sdk.Sfc.Urn[] smoObjects = new Microsoft.SqlServer.Management.Sdk.Sfc.Urn[1] ;
foreach (Table tb in db.Tables) {
smoObjects[0] = tb.Urn;
if (tb.IsSystemObject == false) {
System.Collections.Specialized.StringCollection sc;
sc = scrp.Script(smoObjects);
foreach ( string st in sc) {
Console.WriteLine(st);
}
}
}
}
Although the question has been accurately answered, I struggled for a few days to put together a script that scripted out all the objects I cared about on a database server. Here's my code just in case it is useful to someone else at some point.

There a few ways of scripting all objects in database, but one of the easiest is to you the SMO tranfer class. Here's some PowerShell code to script out all objects:
add-type -AssemblyName "Microsoft.SqlServer.ConnectionInfo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
add-type -AssemblyName "Microsoft.SqlServer.Smo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
add-type -AssemblyName "Microsoft.SqlServer.SMOExtended, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
$sourceSrv = "$env:computername\sql2k8"
$sourceDb = "Northwind"
$server = new-object ("Microsoft.SqlServer.Management.Smo.Server") $sourceSrv
$db = $server.Databases[$sourceDb]
$transfer = new-object ("Microsoft.SqlServer.Management.Smo.Transfer") $db
$transfer.CopyAllObjects = $true
$transfer.DropDestinationObjectsFirst = $true
$transfer.CopySchema = $true
$transfer.Options.IncludeIfNotExists = $true
$transfer.ScriptTransfer()
