Hello,
I've created a Tool to open selfcrypted Files with special file format.
This Files are encrypted PDF Files with a new ending so Windows things this is a special File Format. (you are not able to open it as normal pdf)
I would now like to open this file with my program as default, to decrypt and access the content.

At the moment the Program has only an open button which then asks for the encrypted file location (open File Dialog)

Question:
First Step is to change the program any ideas?
Next Step tell windows on all PCs to open this File types per default with my program?
So I need to "install" this Program on the Client Computers?

Background and Detail of the Program you'll find in this Question:
"VB.net open File with new NTFS Permissions / open PDF wtih damaged Header"

to associate your tool with the special file format you need to update some registry entries.
for example, if your file format is .abc, then run the following:

My.Computer.Registry.ClassesRoot.CreateSubKey(".abc").SetValue_
	("", "abc", Microsoft.Win32.RegistryValueKind.String)
My.Computer.Registry.ClassesRoot.CreateSubKey_
	("abc\shell\open\command").SetValue("", Application.ExecutablePath & _
	" ""%l"" ", Microsoft.Win32.RegistryValueKind.String)

Open in new window

this code will work if you run it from the tool.
if you want to associate the file format from the installer, then u need to replace the Application.ExecutablePath with the tool exe location on the file system.
so if the tool .exe is installed in c:\program files\Tool
then u need to replace Application.ExecutablePath with " c:\program files\Tool\tool.exe"

Sorry I stuck with another problem which has more priority jet
I need to disable hide the adobe floating toolbar (small gray toolbar appears after moving mouse)

I use the vb.net object "AxAcroPDF1" and I need to ensure user are not able to copy the document. I already secured the pdf so print out is disabled but how to disable save option?
