Abstract:
AutoCAD is a plotting tool familiarized and often used. If the database information associated with the graph can be directly found in AutoCAD, It will not only save cost when the user does not purchase softwares such as Mapinfo,Automap etc., but also lighten the user's learning burden. This method has been realized by using ActiveX Automation technique and VB6.0. Firstly, a selection set of current entity graph is constructed to form a block, and the block is named by the associated searching keyword. Secondly,when searching database information associated with the graph, users can click this block and get this block name and the searching result will be displayed by using the block name as the searching keyword. The above implementation method is discussed and some key source codes is given in this paper. A application example to search the devices information in power supply departments' hookup is also given.
