The BITMAPINFOHEADER contains information about the color space and dimensions of a DIB.

The unmanaged size of the structure must be set before the structure can be used by the API. This can be done by using the Init() call which uses the Marshal.SizeOf(this) method to get the appropriate size.

Since the DEVMODE members beyond dmDisplayFrequency do not have to be declared, the structure can vary in size. You should set dmSize to effective size of your implemetation before calling API functions:

This way the API is informed of the version of DEVMODE used.

Actually, this is NOT working. The only solution I've found so far is using the API Kernel32.dll function FileTimeToSystemTime, then transforming from that into a regular DateTime.

When starting to work with the Ghostscript Interpreter API (gsapi.dll), it is helpful to start by getting the gsapi_revision function to work.

Here is a sample of how the GSVersion structure is filled in by the gsapi_revision function.

Originally this article showed the 'product' and 'copyright' fields as type 'string', but this causes a program crash when calling the gsapi_revision function (tested under VS2013 and 32-bit GPL Ghostscript v9.15).

pApplicationId: a string that supplies a vendor-defined token. DIFxAPI uses this token to associate an application with the driver package. This token should be a unique application-specific value, such as a GUID. DIFxAPI does not enforce uniqueness among the tokens. If a caller supplies an INSTALLERINFO structure that specifies an association between an application and a driver package, this member must not be NULL or supply an empty string.

pDisplayName: a string that supplies the display name of an application that is associated with a driver package. DIFxAPI requires an application display name to inform a user which application is associated with a driver package. For example, if a user clicks on the Remove button of an Add or Remove Programs entry that was created by the DIFx tools to represent a driver package, the resulting user dialog box will list the display names of the applications that are associated with the driver package. If a caller supplies an INSTALLERINFO structure that specifies an association between an application and a driver package, this member must not be NULL or supply an empty string.

This is named "struct" to be consistent with the Windows API name, but it is defined as a class since it is passed as a pointer (AKA reference) in SetWindowsHookEx and CallNextHookEx. Or it can be defined as a struct and passed with ref (ByRef in VB.NET).

Alternative Managed API:

The CLR offer us no way to tell us that memory is getting tight. Many think this API provides the best solution. This is mentioned by Jeffrey Richter in his book 'CLR via C#' ISBN: 0-7356-2163-2. It is useful in determining if your system is under excessive memory load by looking at the dwMemoryLoad member of the MEMORYSTATUSEX structure. If this value is > 80 (per Mr. Richter in his discussion of Garbage Collection), it is an indication that you might want to consider converting some strong references into weak references. Remember that a weakreference type will be collected when Generation 0 is full, so it is not a good technique for caching (as many seem to think).
