Brug af andet program når der vælges \"vis kilde\"

i browseren:
værktøjer - internet indstillinger - fanebladet programmer - html editor

Dette har jeg kigget på... men jeg har kun mulighed for at vælge mellem notepad og word, og altså ikke det program som jeg gerne ville anvende....

Du kunne jo evt. kalde dit hjemmelavede program for notepad.exe og overskrive den originale notepad.exe fil.

How to change the default editor for use in viewing the source of web pages
(requires I.E. 5.0 or later)

In the registry editor navigate to HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Internet Explorer.
If a View Source Editor key does not exist create one.
Inside the view source editor key create an Editor Name key if one does not exist.

When you finish the fully qualified path to where you are  currently in the registry should be HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Internet
Explorer\\View Source Editor\\Editor Name
 
In the right hand pane double click on the listing for default.
In the resulting string box enter a fully qualified path to a  program file in the form of x:\\directory\\filename.ext then click the OK button.
