The Stub Global Hook DLLs tab allows you to detect and specify global hook DLLs that may not be wanted in the stub process.

 

 

 

About global hook DLLS

 

Some third party products such as storage devices and video cards are supplied with software to help integrate the hardware device into the computer desktop environment.

 

An example is the Iomega® Zip® drive. This uses a global hook via the IMGHOOK.DLL which allows the browse for files and browse for folders interfaces to correctly display all the storage devices on the computer, including the zip drive and any special options for the drive.

 

Some global (or system) hook DLLs can interfere with the correct operation of Performance Validator when it inserts hooks into the target program, (although the IMGHOOK.DLL mentioned above doesn't).

 

The settings below allow you to specify and/or detect DLLs that should be treated as global hook DLLs.

 

Any DLL listed will fail to load into the target program when loaded via LoadLibrary() or LoadLibraryEx().

 

For situations where the hook DLL is already present in the target program, it can optionally be forcibly unloaded. This may happen if it was loaded before Performance Validator attached to the process.

 

 

Managing global hook DLLs

 

•Add File... browse and select one or more DLLs Open adds the chosen DLLs to the Global Hook DLLs list

 

•Remove removes any selected DLL from the list

 

•Remove All removes all DLLs from the list

 

 

Auto detecting global hook DLLs

 

Performance Validator can detect any DLLs in its own process that are not ones it uses itself. Such DLLs are likely to be global hook DLLs:

 

•Auto Detect automatically detect DLLs which may be global hook DLLs, adding them to the Global Hook DLLs list

 

Additionally, you can request unloading of any of the listed global hook DLLs that are detected as already loaded into the target process when Performance Validator attaches to it:

 

•Unload already loaded global hooks when ticked, forces an unload of any listed global hook DLLs

 

Use this with caution, as not all global hook DLLs may have been designed or intended for this!
