Ciao Luca,

    as far as I know, it's possible. Try to drop a TADODataSet 
onto a TDataModule (or TForm), then rename it (e.g. DS). Then 
try to write something like the following (untested) code 
snippet:

    // Clear all field
    DS->FieldDefs->Clear();

    // Create the first field
    TFieldDef *NewDef = DS->FieldDefs->AddFieldDef(); 
    NewDef->Name = "Field1";  // Field name
    NewDef->DataType = ftInteger; // Field Type

    // Create the 2nd field
    NewDef = DS->FieldDefs->AddFieldDef();
    NewDef->Name = "Field2";  // Field name
    NewDef->DataType = ftString; // Field Type
    NewDef->Size = 30;  // Length

    // and so on ... 

    // Now, here we create the recordset. Don't try to open DS;
    // just call TADODataSet::CreateDataSet();
    DS->CreateDataSet();

HTH

Ciao!
