Summary

Synopsis

Applies to InstallScript projects. This article associates a different icon file with an already existing file extension.

Discussion

Call RegDBSetKeyValueEx, or use a registry set, to change the data in the extension's DefaultIcon registry key.

HKEY_CLASSES_ROOT\<file extension type>\DefaultIcon

For example:

HKEY_CLASSES_ROOT\htmlfile\DefaultIcon

This registry key's "Default" registry value contains the path to the specfied icon is for the file extension. The string data in the DefaultIcon key can have either of the following formats:

"<path to icon file>"

For example:

"C:\Myicon.ico"

or

"<path to dll or exe>,<icon index>"

For example:

"C:\Mydll.dll,2"

If the data is an executable file's name with no icon index, the first icon in the file (the icon with index 0) is used.
