摘要： In association with a computer system, a method and system for detecting and correcting errors in a spreadsheet formula. A token is created corresponding to each entry in the formula. As the formula is constructed, each token is added to the top of a formula token stack. When the formula is completed, a parser parses the formula token stack starting at the bottom of the stack and parsing each subsequent token. By examining the tokens in the formula token stack and their relationship to other tokens, the system determines whether an error exists in the formula. If an error is found to exist in the formula, an error class code is assigned to the error corresponding to the type of error. An error corrector rule corresponding to the error class code is applied and identifies a correction for the error. After a correction for the error is identified, the remainder of the formula token stack is parsed to detect and correct any other errors. When the entire formula token stack has been parsed and all detected errors have been corrected, a dialog box is displayed containing the completely corrected formula.

摘要翻译： 与计算机系统相关联的用于检测和校正电子表格公式中的错误的方法和系统。 对应于公式中的每个条目创建令牌。 随着公式的构建，每个标记被添加到公式令牌堆栈的顶部。 公式完成后，解析器将从堆栈底部开始解析公式令牌堆栈，并解析每个后续令牌。 通过检查公式令牌堆栈中的令牌及其与其他令牌的关系，系统确定公式中是否存在错误。 如果公式中存在错误，则将错误类代码分配给与错误类型相对应的错误。 应用与错误类代码相对应的错误校正规则，并识别错误的校正。 纠正错误后，解析公式令牌堆栈的其余部分，以检测和更正任何其他错误。 当已经解析了整个公式令牌堆栈并且所有检测到的错误已被更正时，将显示一个对话框，其中包含完全校正的公式。

摘要： A method and system for assisting a user in constructing a formula in a cell of a spreadsheet operating on a computer system. A function dialog box is displayed that lists various functions that may be selected by the user to be entered into the formula. By selecting a button in the function dialog box, an insert function dialog box is displayed that lists additional functions by category. When the user selects a function, a parameter dialog box associated with the selected function is displayed. Parameters may include cell addresses as well as numerical or other data entered directly by the user. The parameter dialog box displays the formula as it is being constructed. After the parameters have been entered, a result dialog box is displayed that allows the user to select the result cell in which to place the formula. The user selects the result cell and the result dialog box is removed from the display screen, the formula is entered in the result cell, and the result of the formula is displayed in the result cell.

摘要： Various technologies described herein pertain to delivering shared WiFi credentials. According to various embodiments, at least one server computing device is configured to transmit shared WiFi credentials to a mobile device. The at least one server computing device receives a request, where the request includes data that identifies the mobile device. Moreover, the request indicates that the mobile device desirably receives credentials for a shared WiFi network. Responsive to receiving the request, the at least one server computing device determines that the mobile device is authorized to receive the credentials for the shared WiFi network based at least in part upon the data that identifies the mobile device. Moreover, the at least one server computing device transmits the credentials for the shared WiFi network to the mobile device responsive to determining that the mobile device is authorized to receive the credentials for the shared WiFi network.
