These seem to be the 3 biggest offenders with regards to missing OCX's

You can find these in numerous places around the web and of course from Microsoft themselves. 

You should be able to just copy them into the dreamView directory, or alternatively you should copy them, where appropriate into your system32 directory and register them with;

regsvr32 COMCTL32.OCX + Return

If you decide to copy them over existing files please make sure they are newer than the ones you are overwriting and it would be wise to unregister the old ones first with; 

regsvr32 /u COMCTL32.OCX + Return
