I want to get a lookup for all available table names in the system. 

I know to achieve this on a dialog but now I want a lookup on a stringedit/combobox on a form.

The only way I know is to create a table with a field bounded to RefTableId/TableName EDT and override the lookup method like shown below

Step 1 : Create a field on your table and bound it to TableName EDT

Step 2 : Create a new form and select your table as Data Source

Step 3 : Override the lookup method with this code

public void lookup()

{

            SysTableLookup              sysTableLookup = SysTableLookup::newParameters(tablenum(SYSTABLEIDVIEW), this);

            Query                       query = new Query();

            QueryBuildDataSource        queryBuildDataSource;

            QueryBuildRange             nameQBR, typeQBR;

            

            sysTableLookup.addLookupfield(fieldnum(SYSTABLEIDVIEW, SqlName));

            sysTableLookup.addLookupfield(fieldnum(SYSTABLEIDVIEW, Id));



            queryBuildDataSource = query.addDataSource(tablenum(SYSTABLEIDVIEW));



            sysTableLookup.parmQuery(query);

            sysTableLookup.performFormLookup();

}

et voilà
