Oprette egne filtyper

just a guess. You need to associate the fiel type with the program (your program) so this will mean adding your program to the list.

To associate a file with a program
Open My Computer.
Double-click a drive or folder.
Right-click a file, and then click Open With. If Open With is not available, click Open.
Follow the instructions under the option that matches the dialog box you see:

In Th e"Open With" dialog you can browse after th eprogram you want to use to open the specific file type

Hmm - tror du mener noget andet end det terry beskriver. Vil du have en "krypteret" fil, der kun giver mening for dit eget program? Altså en eller anden form for binær fil, der indeholder data som dit program kan læse, og åbnes filen af et andet program, er der kun volapyk?

Hvad skal filerne indeholde - data, billeder, ..?

Your probably right there martin_moth. Actually I was thinking on th esame lines as you but decided that even if the file is "krypteret" there is NOTHING from stopping me from "opening" it for example in NOTEPAD. I maybe cant read it be even so :o)

Ja Martin, du har ret, jeg vil have en fil som kun mit program kan læse. Filen skal indeholde data.

Hva' med at bruge en database fil med password?

Eller registreringsdatabasen?

Bare lige for at lege Kloge Åge her...krypteret=encrypted ;)

stry?

Lukker da det ikke længere er aktuelt, undskyld for den lange responstid - jeg havde glemt spørgsmålet :-D
