Code To View A HTML File

From WxWiki

Jump to: navigation, search

This sample will use the system's registered http:// handler, usually the Default Browser, to display the passed URL. The URL may also be an absolute filename, in OS canonical form, eg "c:\subdir\filename.html", without the preceding "file://".

It accepts UNC paths in the form "\\server\share\file.html" on windows only.
