I am currently using the TBatchMove component within an application I am writing. I have used the following code to try and copy a Table and its indexes into a seperate table under the same directory. I used the batCopy command to copy and it copies the table perfectly but without indexes ?? :(
Can someone help me out the code is shown below :-


  Table1.Active := true ;
  Table2.FieldDefs := Table1.FieldDefs ;
  Table2.IndexDefs.Assign(Table1.IndexDefs) ;
  Table2.CreateTable ;
  Table2.Open ;
  BatchMove1.Execute ;

I checked the directory under DOS and it verifies that the only file made was the .DBF file no .MDX file.
HELP HELP HELP. Can it be done with TBatchmove ??

Hi, don't know about the batchmove method but this will work :

DbiCopyTable example

From: "David S. Becker" <dsb@plaza.ds.adp.com>

Here is an example of a routine that I use for copying and deleting tables. It uses DB, DBTables, DbiProcs,DbiErrs, and DbiTypes. You simply provide the directory to copy from, the source table name, the directory to copy to, and the destination table name, and the BDE will copy the entire table, indexes and all to the new file. The delete function takes the path to delete from and the name of the table to delete, the BDE takes care of deleting all associated files (indexes, etc.). These procedures have been pulled off a form of mine, and I've edited them to remove some dependencies that existed with that form. They should now be completely stand-alone. (If they compile, that is! :) Use in good health, and enjoy!

-----------------------------------------------------------------
procedure TConvertForm.CopyTable(FromDir, SrcTblName, ToDir, DestTblName: String);
var
  DBHandle: HDBIDB;
  ResultCode: DBIResult;
  Src, Dest, Err: Array[0..255] of Char;
  SrcTbl, DestTbl: TTable;
begin
  SrcTbl := TTable.Create(Application);
  DestTbl := TTable.Create(Application);
  try
    SrcTbl.DatabaseName := FromDir;
    SrcTbl.TableName := SrcTblName;
    SrcTbl.Open;
    DBHandle := SrcTbl.DBHandle;
    SrcTbl.Close;
    ResultCode := DbiCopyTable(DBHandle,false,
      StrPCopy(Src,FromDir + '\' + SrcTblName),nil,
      StrPCopy(Dest,ToDir + '\' + DestTblName));
    if (ResultCode <> DBIERR_NONE) then
    begin
      DbiGetErrorString(ResultCode,Err);
      raise EDatabaseError.Create('While copying ' +
        FromDir + '\' + SrcTblName + ' to ' +
        ToDir + '\' +   DestTblName + ', the '
        + ' database engine   generated the error '''
        + StrPas(Err) + '''');
    end;
  finally
    SrcTbl.Free;
    DestTbl.Free;
  end;
end;

procedure TConvertForm.DeleteTable(Dir, TblName: String);
var
  DBHandle: HDBIDB;
  ResultCode: DBIResult;
  tbl, Err: Array[0..255] of Char;
  SrcTbl, DestTbl: TTable;
  SrcTbl := TTable.Create(Application);
  try
    SrcTbl.DatabaseName := Dir;
    SrcTbl.TableName := TblName;
    SrcTbl.Open;
    DBHandle := SrcTbl.DBHandle;
    SrcTbl.Close;
    ResultCode := DbiDeleteTable(DBHandle,
      StrPCopy(Tbl,Dir +   '\' + TblName),nil);
    if (ResultCode <> DBIERR_NONE) then
    begin
      DbiGetErrorString(ResultCode,Err);
      raise EDatabaseError.Create('While deleting ' +
        Dir +   '\' + TblName + ', the database ' +
        'engine generated the error '''
        + StrPas(Err) + '''');
    end;
  finally
    SrcTbl.Free;
  end;
end;

Have you used an error check for the TBatchMove? Did it gave you errors?

Have fun,
