A method and system for capturing and managing electronic notes in a computer based application is presented. Electronic notes are captured in a note object and the context of the captured note is associated to the note object. Note objects are stored in a notes database for later retrieval. The notes can be queried, filtered, and sorted to obtain useful information from the notes.

A new application sharing technology that enables sharing of many single-user non-modified applications between two or more workstations. It provides concurrent sharing of existing multiple applications with no change in a distributed environment. It permits real-time sharing of distributed applications based on a fundamental window hierarchical mapping and user interactions. Control is centralized but the data and program are replicated. It is event driven with agent assistance. The new event capturing capability is automatically triggered by user interactions on entering/leaving the shared window. The event capturing capability starts when the user moves the pointer into the shared windows. The event capturing ends when the user moves the pointer out of the shared windows. The new multicasting scope is defined in a shared window hierarchy data array. This global data array is dynamically created at run time on an as-needed basis. Because this mechanism only processes user input events such as mouse, keyboard or cursor movement (commands), no output graphic data transmission across the network is required. Therefore, this approach is extremely light-weight and provides secure transmission without requiring intensive encryption. Because it is not using pseudo server interception, this approach can support DHA 3-D rendering. Also, the agent can dynamically mediate resources and normalize environment differences. This permits real-time sharing of 3-D, graphic and DHA (direct hardware access) applications. DHA permits the application to bypass the windowing server to render graphics on display. Moreover, because it is extremely light-weight, high network bandwidth is not required.

A system that translates the color of a pixel being displayed in a first visual type into a comparably colored pixel for a second visual type. The system first allocates a ramp of colors evenly distributed over the color palette of the second visual type, with the ramp occupying half of the colormap in the second visual type. For each pixel displayed on the first visual type, the colors of the pixel are matched to the ramp and if a close color is in the ramp, it is displayed on the second visual type. If no ramp color is sufficiently close, a new color is allocated in the colormap of the second visual type, if possible. Color translations are retained and used again when possible. When read-only and read-write classes of colors are used, a corresponding class is defined in the second visual type's colormap.

A method and apparatus for sharing a local display signal from a local computer display to at least one remote computer display includes generating a connection with the display server associated with the remote computer display in response to a signal from the local workstation input device generating a remote display signal in relation to the local display signal in response to a second signal from the input device. The generation of the remote display signal involves dynamically creating a list of display resources for the remote computer display and generating the remote display signal in relation to the display resources and transmitting the remote display signal to the remote display server. Where the local display signal is shared among multiple remote computer displays, the generation of remote display signals creates a list of display resources for each of the remote computer displays, which list is updated for each rendering of the local display signal. In such a situation, the remote display signal for each remote computer display is generated in relation to the associated display resources. In one embodiment, the local display signal is a window based display signal, preferably X-windows. The generation of such a window based signal defines a window instance. Graphics contexts are dynamically allocated for each window instance and are stored remotely while identification information is stored locally.

A memory resource is managed by allocation of memory blocks within a larger free memory block to reduce fragmentation and provide efficient methods for consolidation of previously allocated memory blocks into larger free memory blocks.
