An invention is disclosed for using multi-touch input in a remote presentation session. In embodiments of the invention, a client computer is configured to locally receive both mouse and keyboard input, and multi-touch input. Where the client computer receives mouse or keyboard input, it sends this input to a remote presentation session server via a TCP connection. Where the client computer receives multi-touch input, it sends this input to the remote presentation session server via a UDP connection. The server computer processes input received from the client computer, via either the TCP or UDP connection, and sends the client a graphical result of performing processing corresponding to that received input.

Multi-touch remoting

Accessing and controlling a remote desktop of a remote computing system using a multi-touch display of a local computing system. The remote desktop is displayed on the multi-touch display. Upon detecting a user contact with the multi-touch display when the display is not engaged as a trackpad, the multi-touch display is engaged as a trackpad; and the user contact is assigned as a cursor pointer for controlling the multi-touch display as a trackpad. In accordance with some embodiments described herein, left and right pointer controls (e.g., left mouse button and right mouse button) controls may be emulated also. This remote desktop technique allows multi-touch displays to be used to manipulate remote desktops, even for those that do not support multi-touch semantics, interaction techniques, or metaphors.

Remote session control using multi-touch inputs

Implementations of the present invention efficiently establish secure connections between a client and server, at least in part by authenticating the client and server early on in the connection setup phases. A client initiating a connection with a server identifies the secure communication protocols enabled at the client, and identifies these protocols in a connection request it sends to the server. The server processes the message and responds with a communication protocol it deems appropriate for the connection. The client and server then exchange appropriate authentication information, and then establish a connection session that implements the chosen communication protocol, and encrypts messages using the negotiated communication protocol. Additional implementations relate to reestablishing dropped connections behind virtual Internet Protocol addresses, without necessarily having to recommit much connection resource overhead.

Creating secure interactive connections with remote resources

Systems, methods and computer readable media are disclosed for reducing the tearing of display data received across a communications network. A server determines at least two logically related drawing orders in an order heap and warps those orders with a begin marker and an end marker. It sends those wrapped orders across the communications network to a client. The client receives those orders and renders them to a shadow buffer. When the client processes the end marker, it moves the drawing orders in the shadow buffer to a client display surface.

Tear-free remote desktop protocol (RDP) display

Example embodiments of the present disclosure are related to scrolling the view of a virtual desktop on a client. The client can be in communication with a server that has a display driver. The server can be configured to transmit signals indicative of images to the client and the client can be configured draw the images in a virtual desktop. The client can be configured to render a view of the virtual desktop that includes a portion of the virtual desktop; track user input; and pan the view in response to the user input.

Virtual desktop view scrolling

The present invention extends to methods, systems, and computer program products for dragging and dropping objects between local and remote modules. Terminal server components simulate the functionality of participants in drag and drag operations to facilitate the dragging and dropping of objects between local and remote modules and vice versa. The terminal server components interact locally to communicate with modules participating in a drag and drop operation. The terminal server components also send messages over a terminal server session to relay appropriate drag and drop information to corresponding terminal server components on the other end of the terminal server session.

Dragging and dropping objects between local and remote modules

Present implementations include one or more applications at a sending computer system that generate data intended for display at a receiving computer system over a network connection. A mirror driver at the sending computer system renders shared data in a bitmap, which is sent to the receiving computer system. The mirror driver also renders one or more simple image files in place of unshared data that is not intended for display, and sends the replacement images to the receiving computer system. The receiving computer system, in turn, renders what it receives using its existing resources. In one implementation, a driver interface mediates at the sending computer system between the one or more applications generating data, one or more display drivers, and the mirror driver. Thus, the driver interface can pass data to a normal display driver, and also to the mirror driver, which then filters the data as appropriate.

Filtering obscured data from a remote client display

Embodiments herein address some of the problems associated with compromised configuration files used in a remote sessions of a virtual computing environment. Accordingly, a subset of settings in a configuration file are secured from malicious or accidental modification, while other portions of the configuration file are modifiable by a user as desired without invalidating the integrity of the secure subset. This not only allows for the user to be assured of the integrity of the settings, but also allows an administrator of the remote or terminal server with the ability to control how and what access a client has to resources thereon. Such access may be further controlled based on a trust level between the client, server, and/or publisher of the configuration file.
