Is it possible to create a standalone application using Midas and C++ Builder 6 
? I am using TClientDataSet in a BCB6 application I need to be a standalone 
application. The application accesses the BDE and ADO database components and 
uses a TClientDataSet in order to create an in-memory dataset from ascii files.

If by stand-alone you meant shipping a single exe file, then you could put 
the Midas DLL in the executable's resource.
Here's how we check if Midas is installed:
    auto_ptr<TRegistry> registry ( new TRegistry ) ;
    registry->RootKey = HKEY_CLASSES_ROOT ;
    registry->OpenKeyReadOnly("\\CLSID\\{9E8D2FA1-591C-11D0-BF52-0020AF32BD64}\\InProcServer32" 
 ) ;
    String midasDLL = registry->ReadString("") ;
    registry->CloseKey() ;


    if( midasDLL.IsEmpty() || !FileExists( midasDLL ) )
    {
        if( ! midasDLL.IsEmpty() )
            ShellExecute( Application->Handle, "open", "regsvr32.exe", "/s 
midas.dll", NULL, SW_HIDE ) ;


        // Extract the dll from the resource
        ...
    }


HTH,
Stephane

I just came accross this link to a Midas replacement which is free and comes 
with source (so could be linked-in).
  http://www.vglib.com/link-4.html
Note that I haven't tried it.
