Windows消息子类化及应用

Win32消息处理机制是Win32应用编程的核心内容之一。Windows窗口消息的子类化,是根据消息处理的基本原理,把发送或投递到一个窗口的消息交给自己定义的函数处理,而不是交给默认的窗口过程处理。利用窗口子类化,开发者可以实现对应用程序的窗口消息进行独特的处理。     

Interpersonal communication motives and message design logic: exploring their interaction on perceptions of competence

Message design logic and interpersonal communication motives were conjointly studied to assess their interaction on receivers' perceptions of senders' competence. Two 8 (motive)×3 (message design logic) repeated measures ANOVAs indicated significant interaction effects for both effectiveness and appropriateness. Nevertheless, the effects of design logic and motive on perceptions of competence were not as expected for some situations. The results of the study fail to support past research suggesting that perceived effectiveness and appropriateness will be enhanced by using a more complex message design. In addition, no pattern emerged for the instrumental versus the ritualistic motivations in terms of the most competent message design.     

Syntactic Indeterminacy,Perceived Message Sensation Value-Enhancing Features,and Message Processing in the Context of Anti-Tobacco Advertisements An earlier version of this manuscript was presented at the 2004 National Communication Association Annual Convention in Chicago,IL, November 11–14, 2004

Fast-paced and arousing anti-drug ads, considered to have high perceived message sensation value (PMSV), enhance message processing and reduce drug use among young adults. Studies have yet to explore the relationship between specific, PMSV-enhancing message features and outcomes related to persuasion. Messaris’ (1997) concept of syntactic indeterminacy provides one plausible explanation for why message features contained in high PMSV ads might enhance message processing and subsequent changes in attitudes and behavior. The study explored this explanation by coding specific anti-tobacco ads for PMSV-enhancing features, merging these codes to a telephone survey among teens, and testing the relationship between message features and processing. The number of unrelated cuts and the use of suspenseful features (intense imagery and a second-half punch) increased message processing among older teens. An additive index comprised of these features was associated with message processing among both younger and older teens. Theoretical and practical implications are discussed.     

The Froude‐Burke controversy

This study investigated the impact of age, task complexity, and practice on adult message‐production‐skill acquisition and performance. Participants (30 older adults and 30 college students) learned a sequence for describing geometric arrays and then employed this organizing sequence in a series of 90 performance trials. Half of the participants learned a six‐step (high task‐complexity) sequence, while the remaining participants learned a three‐step (low task‐complexity) sequence for describing the arrays. The results suggest that overall message‐production speed is characterized by a “complexity effect” (i.e., an interaction between age and task complexity such that younger adults exhibited superior performance relative to their older counterparts, and this difference was more pronounced under complex‐task conditions). Complexity effects were also found for initial message‐production‐skill performance and rate of skill acquisition: older adults exhibited slower initial performance and slower rates of skill acquisition than younger adults, and this difference was even more pronounced when learning a complex skill. Finally, the results indicate a significant main effect for age on variation in overall task performance in that older adults’ learning curves, regardless of task complexity, were characterized by greater variability in performance quality from trial to trial. These effects are consistent with changes in processing speed and working‐memory capacity that have been suggested to accompany advancing age. The current findings may be seen to have direct implications for older‐adult‐skills training.     

The association between immediacy and socio‐communicative style

The very strong association of immediacy with positive instructional outcomes has led some to question whether teacher immediacy amounts to anything more than being responsive with students. The present study demonstrates that a measure of teacher immediacy is strongly associated with the Socio‐Communicative Style of the teacher—both the assertiveness and the responsiveness components. It is concluded that it is theoretically justified to teach pre‐service or in‐service teachers to engage in immediate behaviors as means of increasing their communication competence and probably teaching effectiveness. The impact of immediacy observed in the classroom environment is seen as likely to be generalizable to other communication contexts.     

Changes in Advertising Strategies During an Economic Crisis: An Application of Taylor's Six-Segment Message Strategy Wheel

Between 2005 and 2009 financial service organizations in the United States altered their advertising messages in response to changing economic conditions brought about by a sustained recession. This analysis of print magazine advertisements for banks, credit cards, investment firms, and insurance providers demonstrates that financial service advertisers shifted away from transformational approaches in favor of informational approaches. Credit card companies were slower to change their strategies than were bank, investment, and insurance companies. The results of this analysis support the argument that advertising serves the role of providing market information and that the nature of such information is determined by economic conditions.
