SYMPTOMS
When trying to pass dbAttachedTable or dbAttachedODBC as arguments to the CDaoTableDef::Create function or the CDaoTableDef::SetAttributes function, you will receive this DAO error:

Error Code = 3001

....

Description = Invalid argument.



CAUSE
The Visual C++ documentation is incorrect. The values dbAttachedTable and dbAttachedODBC cannot be passed as arguments. These attributes are read- only attributes that are set internally by DAO based on the information provided in the connect string of the table.



RESOLUTION
Do not try to set these attributes. DAO will set the attributes based on what is contained in the connect string for the table. For example, look at this code: td.Create(_T("Table1"),0,_T("Table1"),     _T("FoxPro 2.6;DATABASE=d:\\mydatabase\\")); DAO will set the dbAttachedTable attribute flag for that table. A call to CDaoTableDef::GetAttributes will show the flag has been set.

<div class="status_section">

STATUS
This behavior is by design.
