Windows API函數(shù)大全.doc

Windows API函數(shù)我們知道VB可以做很多事，但是有些事情，特別是涉及對Windows操作系統(tǒng)的訪問，還需要借助Win32 API函數(shù)(Microsoft Win32 Application Programming Interface的縮寫)。API函數(shù)是一組用C語言編寫的函數(shù)，總共約有一千來個。原本是為C語言編程人員而編寫的，但也可以在VB應(yīng)用程序中調(diào)用。按功能劃分，Win32 API函數(shù)大致涉及以下幾個方面：窗口管理、圖形設(shè)備接口、系統(tǒng)管理和多媒體技術(shù)。Win32 API函數(shù)以動態(tài)鏈接庫DLL提供給用戶，可以在任何語言中調(diào)用。DLL在程序運行時裝入，隨時響應(yīng)程序的調(diào)用，不必在設(shè)計時就將文件存放在工程中，這就是動態(tài)鏈接的意思。正因為如此，一個DLL程序可以同時為多個程序所調(diào)用。在VB中引用API函數(shù)，需要事先通過Declare函數(shù)，聲明要引用的DLL文件名稱以及相應(yīng)函數(shù)的參量。然后便可像使用VB函數(shù)一樣使用API函數(shù)。 我們看以下類似的聲明語句：Declare Function GetComputerName Lib kernel32 Alias GetComputerNameA (ByVal lpBuffer As String, nSize As Long) As LongGetComputerName是API函數(shù)名，kernel32是庫名。括號中的ByVal lpBuffer As String, nSize As Long就是函數(shù)的參量。最后面的Long表示函數(shù)返回值的數(shù)據(jù)類型。本節(jié)通過例子說明Win32 API函數(shù)的應(yīng)用。Windows在創(chuàng)建每個窗體時，都會賦給它一個與眾不同的編號,這就是窗體的句柄。 在Windows中，窗體與控件都被看成是窗體(窗口)。窗體的句柄保存在自己的hwnd屬性中。一GetComputerName【功能說明】函數(shù)用于獲得計算機的名稱【函數(shù)聲明】Declare Function GetComputerName Lib kernel32 Alias GetComputerNameA (ByVal lpBuffer As String, nSize As
