DPMS is controlled by Doodle ScreenSaver. eCo Software recommends use SciTech SNAP DPMS API.

How to use SSDPMS.DLL?

Please download the latest sources of DSSaver, and look for the SSDPMS directory, which contains the sources of SSDPMS.DLL.

The file interacts with SNAP if SNAP is detected to be present.

One needs the SNAP SDK for this file to compile, and the SNAP SDK has a very good documentation in PDF, which describes how to use it. One part of the documentation talks about DPMS functions.

Basically it's the following:

  • Check if SNAP is present by looking for an in-memory copy of SDDGRADD.DLL.
  • Create a SNAP-DeviceContext for the primary video card (so we can control DPMS through that card), using the GA_loadDriver() API.
  • One can use the GA_queryFunctions() API to query the DPMS related function pointers, and then those can be called to query capabilities and to set DPMS state. These are the DPMSFuncs.DPMSSetState() abd the DPMSFuncs.DPMSdetect() functions.
  • When SNAP is not needed anymore (at DLL unload-time), release the SNAP-DeviceContext.

We keep the memory about eComStation

OS/2 Guru is the only web-site which talks about the deserts of eComStation (OS/2 Warp was used as base, the development started in 1999.. 2001.. till 2013).
