1. I'm creating an Access database on the fly using ADOX via COM
Interop.

2. I create a CatalogClass, create TableClass and append ColumnClass to
the table as required.

3. In one such table, I have two text fields (adVarWChar) called
"CutterID" and "Material".

4. I want to define a primary key consisting of both the columns taken
together, i.e. the combination of CutterID and Material is to be unique
for each record.

5. To do so I used the sample on
http://support.microsoft.com/default...b;en-us;252908

6. My code looks as follows-

// Have to use the ADOX.Key object
ADOX.KeyClass key = new ADOX.KeyClass();
key.Name = "PrimaryKey";
key.Type = ADOX.KeyTypeEnum.adKeyPrimary;

// These columns have been appended to the tbl before calling this
key.Columns.Append ("CutterID", ADOX.DataTypeEnum.adVarWChar, 0);
key.Columns.Append ("Material", ADOX.DataTypeEnum.adVarWChar, 0);

// THE NEXT LINE CHOKES
tbl.Keys.Append (key , ADOX.KeyTypeEnum.adKeyPrimary, "", "", "");

7. The tbl.Keys.Append call throws exception "Exception from HRESULT:
0x800A0BB9." which means "adErrInvalidArgument:The arguments are of the
wrong type, are out of acceptable range, or are in conflict with one
another." (see
http://msdn.microsoft.com/library/de...erty_oledb.asp)

8. Help with the tbl.Keys.Append syntax please. I've tried every
permutation & combination.

9. Thanks

Sam.

I would recommend using Access SQL DDL instead of ADOX to create your table schema:

Fundamental Microsoft Jet SQL for Access 2000
