      1 引言

      地籍測繪調(diào)查是不動產(chǎn)登記中最基礎(chǔ)的部分,是反映不動產(chǎn)的核心成果。VB語言可以實現(xiàn)在地籍測繪調(diào)查中宗地圖的批量修改、PDF輸出以及房屋的批量轉(zhuǎn)化。本文結(jié)合具體實例,介紹了VB語言在地籍測繪調(diào)查中的具體應(yīng)用,以期方便快捷地實現(xiàn)批量改正及轉(zhuǎn)化。

      2 VB語言簡介

      Visual Basic(以下簡稱VB)是一種通用的基于對象的程序設(shè)計語言,以結(jié)構(gòu)化的、模塊化的、面向?qū)ο蟮摹瑓f(xié)助開發(fā)環(huán)境的事件驅(qū)動為機制的可視化程序設(shè)計語言。

      VB語言便于程序員使用,可以簡單建立應(yīng)用程序的GUI系統(tǒng),同時,又可以開發(fā)相當(dāng)復(fù)雜的程序。VB語言具有以下幾個特點:可視化的設(shè)計平臺、事件驅(qū)動的編程機制、結(jié)構(gòu)化的程序設(shè)計語言、強大的數(shù)據(jù)庫功能。

      3 VB語言在地籍測繪調(diào)查中的實例應(yīng)用

      VB語言既可以實現(xiàn)應(yīng)用軟件的轉(zhuǎn)化又可以實現(xiàn)應(yīng)用軟件的批量改正。應(yīng)用轉(zhuǎn)化軟件可以通過VB語言實現(xiàn)多種軟件之間的轉(zhuǎn)化,如CAD圖形可以通過PDF轉(zhuǎn)化軟件實現(xiàn)轉(zhuǎn)換。VB語言也可以實現(xiàn)宗地圖的批量改正,可以極大地提高工作效率和質(zhì)量。下面通過實例來說明CAD圖形轉(zhuǎn)換為PDF、宗地圖的批量改正,具體分析VB語言在地籍測繪調(diào)查中的應(yīng)用。

      ①CAD圖形轉(zhuǎn)換為PDF,單宗輸出

      Sub 單宗輸出PDF()

      Dim strPath As String

      Dim Message, Title, Default As String

      Message = "輸入宗地文件夾所在地址,僅保留個人宗地文件"

      Title = "地址輸入框"? ? ' 設(shè)置標(biāo)題。

      Default = "D:\CADVBA\SFDFAS"? ? ' 設(shè)置缺省值。

      ' 顯示信息、標(biāo)題及缺省值。

      strPath = InputBox(Message, Title, Default)

      Call FindPathdanzongPDF(strPath)

      End Sub

      ②宗地圖的批量改正
