New Application problems

We STILL have some CARDFILE files that don't warrant converting to a
different application as the budget is not there and also because
they are used so infrequently. (Not my idea to support them, but
rather fiddle with them than look for a new job).

Somethig in WIN XP changed the .CRD file type so that another app is
now linked to them, but the format is wrong, so it doesn't work.

I have the program CARDFILE.EXE, and the ast time we needed it, we
just did a RT-CLICK/OPEN WITH/ and the Browse to the CARDFILE.EXE
ffile and clicked ALWAYS USE. We had no problem. BUt now since this
new app took over the .CRD file type, we cannot do thids anymore.

I went to Registry and put in the following entries creating a new
file type ".crf". The file CARDFILE.EXE was HEXEDITED to change the
"CRD" occurrences to "CRF".

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\CARDFILE.EXE]

[HKEY_CLASSES_ROOT\Applications\CARDFILE.EXE\shell]

[HKEY_CLASSES_ROOT\Applications\CARDFILE.EXE\shell\ open]

[HKEY_CLASSES_ROOT\Applications\CARDFILE.EXE\shell\ open\command]
@="\"C:\\WINDOWS\\CARDFILE.EXE\" \"%1\""

[HKEY_CLASSES_ROOT\.crf]
@="win.cardfile"

[HKEY_CLASSES_ROOT\win.cardfile]

[HKEY_CLASSES_ROOT\win.cardfile\DefaultIcon]
@="C:\\WINDOWS\\cardfile.exe"


After diong thiswhen the specific file (rolodex.crf) is double-
clicked, the CARDFILE application opens, but with a blank uintitled
file displayed. CLicking on FILE/OPEN, a dialog window appears with
the appropriate file type and in the file list, the filename
rolodex.crf is there. Double-clicking the filename brings up the
file with the right entries.

What am I doing wrong to not have the app open the file upon dbl-
click ?

I don't have much hair left to pull out. HELP!
