Module Name:
|
|
|
|
SolidWorks99Plus.cpp
|
|
|
|
Abstract:
|
|
|
|
This patches winhlp32.exe for calls to FTSRCH!OpenIndex only if they come from
|
|
ROBOEX32.DLL. This needs to be written in the shim database otherwise the
|
|
shim will be applied to all the apps using winhlp32.exe (which is bad!).
|
|
|
|
Win2k's winhlp32.exe will only work with index files located in %windir%\Help
|
|
so we need to redirect the location that the app points to.
|
|
|
|
Notes:
|
|
|
|
This is an app specific shim.
