    Abstract: Ranked breakpoints are defined in a computer program that allow a debugger t o determine whether or not to halt execution of the computer program when a ranked breakpoint is encountered based on the rank of the breakpoint compared to a threshold rank. In a preferred embodiment, the threshold rank is the rank of a RunTo function, and the ranked breakpoints only halt execution of the computer program if their rank is higher than the threshold rank of the RunTo function. The present invention thus provides a mechanism for ignoring some or all breakpoints in a computer program when performing debugger functions, such as a RunTo function.

    Abstract: An apparatus, program product, and method rely on user interaction in the ordering search results returned by a search engine. Each of a plurality of records i n a database is associated with a user feedback parameter that is used in ordering the recor ds identified in a result set generated in response to a search request. The user feedback parameter for a given record may be selectively updated in response to detecting multiple accesses thereto by a user and/or in response to detecting that the record is the most recently accesse d record in the result set. In addition, the user feedback parameter for a given record may be configured with a plurality of weights that are respectively associated with particular keywords, such that ordering of the records in a result set can utilize only those weights that are associated with keywords that match a particular search request. Furthermore, a search request data structure may be utilized to store a plurality of search request records, each including a search request identifier identifying a unique combination of keywords, and a result set identifier identifying a subset of a plurality of records in a database that match the unique combination of keywords. The search request data structure may be accessed in response to a search request to locate a search request record including a search request identifier that matches the keywords provided in the search request, with a result set generated that identifies the subset of records identified in the result set identifier in the located search request record.

    Abstract: A web server computer system includes a virus checker and mechanisms for checking e-mails and their attachments, downloaded files, and web sites for possible viruses. The virus checker allows a web server to perform virus checking of different types of information real-time as the information is requested by a web client. In addition, a web client may also request that the server perform virus checking on a particular drive on the web client. If this case, the web server may receive information from the web client drive, scan the information for viruses, and inform the web client whether any viruses were found. In the alternative, the web server may download a client virus checker to the web client and cause the client virus checker to be run on the web client. The preferred embodiments thus eliminate the need for virus checking software to be installed on each web client.

    Abstract: An apparatus, program product and method dynamically adjust the scroll rate used to scroll through the program information for various television programs available to a television viewer to provide a variable rate of scroll for program information presented to the television viewer. The scroll rate may be varied, for example, to emphasize certain program information relative to other program information, e.g., by slowing down the scroll rate to increase the visibility for important program information and speeding up the scroll rate to decrease the visibility of less important program information. Dynamic scroll rate adjustment may be utilized in a number of situations, including in connection with non-interactive electronic program listings, interactive electronic program guides, and electronic overlays, among others. Furthermore, dynamic scroll rate adjustment may be based upon a number of different characteristics of the television programs associated with the displayed program information, including for example, the frequency of access of different television programs, or sponsorship of certain television programs.

    Abstract: An automated way to detect differences in the values of program variables/expressions and the order of execution between one run and another. A collection mode saves the values of expressions/variables at collection points in the program. On a subsequent execution during the detection mode, these saved values of the same expressions/variables are recalled and compared with the current values. Advantageously, the user selects the collection points within the program at which variable information can be gathered and compared; and these collectio n points may include: breakpoints set by a debugging program or by the user; collection points set by the user, and entry and/or exit points and/or points within program structures, such as procedur e calls, control blocks, etc. Setup of the collection mode includes the capability to modify the expressions/variables, the tolerance or the acceptable alternatives, and the position and number of collection points.

    Abstract: A system and method is provided for inserting into a display material copied to a clipboard. A user selects material to be copied the clipboard. The syst em selects and copies to the clipboard additional material. The user selects an insertion point for the user selected material, and the system displays to t he user the user selected material and selective additional material. The syste m selected material is, in accordance with a more specific embodiment, that material which is needed to render the user selected material syntactically correct in the context of the insertion point.

    Abstract: A web server computer system 100 includes a virus checker 125 and mechanisms for checking e-mails and their attachments, downloaded files, and web sites for possible viruses. When an e-mail message contains a detected virus, the message is discarded, and both the sender and recipient are informed via e-mail that the message contained a virus. When an e-mail attachment contains a detected virus, the attachment is deleted, and the e-mail message without the attachment is sent to the web client, along with a message explaining that the e-mail message had an attachment that was automatically deleted because it had a virus. When a downloaded file contains a virus, the downloaded file is deleted, and an error message is sent to the web client to inform the web client that the requested file had a virus. When a requested web site (i.e., Uniform Resource Locator (or URL)) has been labelled as a source for a known virus, a message is sent to the web client stating that a virus may have been downloaded from that URL. In addition, if the requested URL has not been labelled as a source for a known virus, but it contains links that have been so labelled, the web page is processed before being sent to the user to identify those potentially dangerous links. In this manner a web server can perform virus checking of different types of information real-time as the information is requested by a web client.
