When a user performs a cut or copy operation in an application, the application puts the selected data on the clipboard in one or more standard or application-defined formats. Any other application can then retrieve the data from the clipboard, choosing from the available formats that it understands. The clipboard is a very loosely coupled exchange medium, where applications need only agree on the data format. The applications can reside on the same computer or on different computers on a network.
When a user performs a cut or copy operation in an application, the application puts the selected data on the clipboard in one or more standard or application-defined formats.
Any other application can then retrieve the data from the clipboard, choosing from the available formats that it understands. The clipboard is a very loosely coupled exchange medium, where applications need only agree on the data format. The Inter process communication can reside on the same computer or on different computers on a network.
All applications should support the clipboard for those data formats that they understand. For example, a text editor or word processor should at least be able to produce and accept clipboard data in pure text format. For more information, see Clipboard. OLE provides services that make it easy for applications to call on other applications for data editing.
For example, a word processor that uses OLE could embed a graph from a spreadsheet. The user could start the spreadsheet automatically from within the word processor by choosing the embedded chart for editing.
OLE takes care of starting the spreadsheet and presenting the graph for editing. When the user quit the spreadsheet, the graph would be updated in the original word processor document. The spreadsheet appears to be an extension of the word processor.
A software component that uses COM can communicate with a wide variety of other components, even those that have not yet been written. The components interact as objects and clients. OLE supports compound documents and enables an application to include embedded or linked data that, when chosen, automatically starts another application for data editing.
This enables the application to be extended by any other application that uses OLE. COM objects provide access to an object's data through one or more sets of related functions, known as interfaces.
This method requires cooperation between the sending application and the receiving application. The receiving application must know the format of the information and be able to identify the sender.
The sending application cannot modify the memory referenced by any pointers.

Data copy can be used to quickly send information to another application using Windows messaging. For more information, see Data Copy. Applications can use DDE for one-time data exchanges or for ongoing exchanges in which the applications update one another as new data becomes available. The data formats used by DDE are the same as those used by the clipboard.
DDE can be thought of as an extension of the clipboard mechanism.
The clipboard is almost always used for a one-time response to a user command, such as choosing the Paste command from a menu.
DDE is also usually initiated by a user command, but it often continues to function without further user interaction.Collectively, the activities enabled by these mechanisms are called interprocess communications (IPC). Some forms of IPC facilitate the division of labor among several specialized processes.
Some forms of IPC facilitate the division of labor among several specialized processes. What is the simplest method of inter-process communication between 2 C# processes? Ask Question. But asynchronous communication requires a queuing technology like MSMQ or Azure Service Bus or RabbitMQ.
Inter process communication. Why not inherit from List? Mailslots provide one-way communication. Any process that creates a mailslot is a mailslot server. Other processes, called mailslot clients, send messages to the mailslot server by writing a message to its mailslot.
Incoming messages are always appended to the mailslot. The mailslot saves the messages until the mailslot server has read them. Inter Process Communication (IPC) is a mechanism that involves communication of one process with another process.
This usually occurs only in one system. Following are some important terms that we need to know before proceeding further on this topic. Pipes − Communication between two related. I've considered using TCP/IP communication but the delay caused by a missing Y is just too long.
Especially since a lot of XML is processed sometimes.
Same problem with named pipes and similar network-based solutions. Jan 04, · It covers Inter-Process Communication for the Mill CPU architecture family. The talk assumes a familiarity with aspects of CPU architecture in general and C++ programming in particular. The Mill is a new general-purpose architectural family, with an emphasis on secure and inexpensive communication across protection boundaries.
