Greate Job! I installed Flexwiki out of the box and it is not the same. This site is much better (you fixed and improved a lot of things in Flexwiki). Now I am learning more about PInvoke

This only appears to be an issue with VS2008, and it may have been fixed by the time you are reading this, so try to run the project first, and if you click on one of the 'TaskDialog' buttons and see it popup (ie you dont see an exception) then you do not need to take these steps, if you do get an exception, follow the steps below:

As of Windows Vista, SHIL_SMALL, SHIL_LARGE, and SHIL_EXTRALARGE scale with dots per inch (dpi) if the process is marked as dpi-aware. To set these types to be dpi-aware, call SetProcessDPIAware. SHIL_JUMBO is fixed at 256 pixels regardless of the dpi-aware setting.

property, A CM_DRP_-prefixed constant value that identifies the device property to be obtained from the registry. These constants are defined in Cfgmgr32.h.

Guids generated with this will return the name using the FmtIdToPropStgName Function, and can be used to generate a new IPropertyStorage interface with IPropertySetStorage.Create(). The name returned will be filled to 26 chars with the letter 'a' due to the fixed size of a Guid and the fact that we're passing all zeros in the BitArray after the name finishes to reach this size.

This is apparently not accurate as the P/Invoke layer automatically generates a marshaling stub at a fixed address:
