Electric map control based on mapx 的列車調(diào)度監(jiān)控系統(tǒng)電子地圖實(shí)現(xiàn)
Graphic mapping control point 圖解圖根點(diǎn)
Provides a table that maps controls in visual basic 6 . 0 to the corresponding control in visual basic 2005 提供一個(gè)表,該表將visual basic 6 . 0中的控件映射到visual basic 2005中的相應(yīng)控件。
Now vehicle orientations rely on gps information , combine electronic map controls and navigates to the vehicle 目前車輛定位主要依靠車載gps接收機(jī)接收到的全球定位信息,然后結(jié)合電子地圖對(duì)車輛進(jìn)行監(jiān)控和導(dǎo)航。
Also , the character of activex control based on com is introduced , and the advantages and disadvantages of developing activex controls using vc + + are analyzed . after large amount of trials , some helpful experiences and key technologies on developing custom vector map controls are discussed , for example : adding user property pagies the designing and implementing of multicontrok activating property dialog when running the drawing of military signs and construction of curvilinear . a custom activex control - visualized electronical vector map control used in c41sr and g1s is designed . the key analysis - , design and implement used in developing this activex control is proposed as well 對(duì)當(dāng)今三種主流軟構(gòu)件技術(shù)( corba 、 com dcom 、 enterprisejavabeans )進(jìn)行了簡(jiǎn)要的介紹并進(jìn)行了比較分析。介紹了基于com技術(shù)的activex控件的特點(diǎn),分析了利用vc + +開發(fā)activex控件的兩條開發(fā)途徑的優(yōu)缺點(diǎn),給出了經(jīng)過(guò)探索實(shí)踐得到的定制矢量地圖控件的關(guān)鍵技術(shù)和經(jīng)驗(yàn),如自定義屬性頁(yè)的添加、多控制的設(shè)計(jì)與實(shí)現(xiàn)、運(yùn)行時(shí)激活屬性對(duì)話框、軍標(biāo)的繪制及曲線的構(gòu)造等。
