In BCB6 this looks as:
#include <ADODB_tlb.h>
#include <ADOX_tlb.h>
void __fastcall TForm1::Button1Click(TObject *Sender)
{
//Database file
WideString db = "C:\\Temp\\Test.mdb";
if (FileExists(db)) DeleteFile(db);
//Connection string
WideString strConn = WideString("Provider=Microsoft.Jet.OLEDB.4.0;") +
WideString("Data Source=") + db;
{
//Create database
CatalogPtr cat = CoCatalog::Create();
cat->Create(strConn);
}
//Open connection
ConnectionPtr conn = CoConnection::Create();
conn->Open(strConn.c_bstr(), WideString("").c_bstr(),
WideString("").c_bstr(), -1);
tagVARIANT RecAffected;
RecAffected.vt = VT_I4;
RecAffected.intVal = 0;
//Create table - here you can execute any SQL command
conn->Execute(WideString("Create table [MyTable] ([Col1] Int Primary Key,
[Col2] VarChar(15))").c_bstr(),
&RecAffected, adExecuteNoRecords);
}
If you are using BCB5 - be sure to delete all functions with GhostMethod_ in
name from imported type libraries.
