This GUI is an updated and enhanced version of the “StructBrowser” utility submitted to MatLab Central in May 2003. It comes with new interface and an enhanced display. It uses Microsoft TreeView control to display and explore any kind of MatLab structures. The CRC ExploreStruct was designed to expose the contents of the array struct to any depth and plot any of the components. This tool is very useful for programmers using structures in their code
The world s bestselling computer security book--fully expanded and updated is one of the most successful security books ever written. Leverage the valuable insights Hacking Exposed 6 provides to help yourself, your company to fight cyber-crime.
This popular tutorial introduction to standard C++ has been completely updated, reorganized, and rewritten to help programmers learn the language faster and use it in a more modern, effective way.Just as C++ has evolved since the last edition, so has the authors approach to teaching it.
Normally a list view is updated by a user directly by selecting a list view item and then editing or deleting it. New items are usually added at the bottom of the list. This works fine since the user knows which items have been changed or deleted and where the new items will pop up. A drawback of it is that, if the list is sorted, then new items will not be displayed in a sorted way, instead they will be listed in the order of being created.
This updated C++ example demonstrates how to create multimedia messages using the CMmsClientMtm API. The updated example has been tested to support S60 5th Edition and touch UI. Important classes: CMsvEntry, CMmsClientMtm.

The second edition of this popular book has been completely updated to add the new features of the Java Servlet API Version 2.2, and new chapters on servlet security and advanced communication. In addition to completely covering the 2.2 specification, we have included bonus material on the new 2.3 version of the specification.
介紹了當(dāng)前普通標(biāo)記機(jī)控制系統(tǒng)現(xiàn)狀及其存在缺點(diǎn)，給出氣動(dòng)標(biāo)記機(jī)及相頻修正PWM模式的工作原理。采用ATmega16單片機(jī)和USB轉(zhuǎn)換RS232接口器件CH341T實(shí)現(xiàn)驅(qū)動(dòng)控制系統(tǒng)與PC的實(shí)時(shí)通訊，標(biāo)記控制系統(tǒng)可升級(jí)到USB接口。采用基于ATmega16的相頻修正PWM替換555振蕩電路產(chǎn)生的PWM，可直接通過軟件調(diào)整PWM信號(hào)。使用達(dá)林頓三極管TIP122替代直流繼電器驅(qū)動(dòng)高頻電磁閥，使得電磁閥驅(qū)動(dòng)電路簡(jiǎn)單，成本低廉。該控制系統(tǒng)已成功應(yīng)用于氣動(dòng)標(biāo)記機(jī)。
Abstract:
In this paper,the actuality and demerit of the common gas marking machine control systems are described.The operation principle of the gas marking machine and the phase and frequency correct PWM of ATmega16is introduced.The real-time communication between the driving control system and PC by CH341T which its function is translated USB to RS232is realized,the control systems is updated grade to USB interface.The PWM signal can be adjustable by software for the555surge circuit was substituted by the phase and frequency.The high frequency electromagnetic value’s driving circuit by DC relay is replaced by TIP122,therefore,the circuit is become simple and the cost cheap.The control systems has been widely used in gas marking machine.
