Module Name:

OmniPagePro.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Shims ShellExecuteExA. If the user double clicks on an image in the right
|
||
|
|
pane, the app will read the progID key in the registry for .BMP files
|
||
|
|
(HKCR, Paint.Picture\shell\open\command, "(Default)"). Previously, that
|
||
|
|
data had: "C:\winnt\system32\mspaint.exe" "%1". In Whistler, that changed
|
||
|
|
to: rundll32.exe C:\WINNT\System32\shimgvw.dll,ImageView_Fullscreen %1.
|
||
|
|
|
||
|
|
The problem with Carea OmniPage Pro v10 is that on the double click, they
|
||
|
|
will read the regkey, remove the %1, pass the rest of the string to
|
||
|
|
ShellExecuteExA() lpFile. They will put the filename into lpParameters.
|
||
|
|
The problem is that with the new path, "rundll32.exe" needs to be in lpFile
|
||
|
|
and "C:\WINNT\System32\shimgvw.dll,ImageView_Fullscreen <FileToOpen>" needs
|
||
|
|
to be in lpParameters.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is specific to OmniPage Pro.
