Please, help me.
This is a very interesting problem to make a program which will be a browser
(on the base of CHtmlView)or which will be an element of ActiveX and can be opened
from any browser by clicking hyperlink of the file with its own extension.
And either this file or whole html should be encrypted and the class-inheritor
must open it.
The main point of this task is to forbid the user to select a text in the window or
copy screen to memory by the key PrintScreen or by any other special program.
How can it be done? Are there any special window attributes or it is necessary to
override function OnLeftMouseDown or KeyDown...of any class.
Can I do it in VC++ 5.0, translate HTML-tags by myself, or is there anything particular of this type?
Resume: it's necessary to output to the screen the content of the file, so
that nobody can copy it and the file downloads encrypted, saves encrypted in the disk and is
situated encrypted in memory.
So we need client and server. Server must define user authority, operate with his keys, encrypt
file before sending. Client recover file, can save and restore this file on local disk.
Thank you Very MUCH
