在VBA中,`Declare`语句用于声明自定义函数或子程序。以下是`Declare`语句的语法: ```vba [Public|Private] Declare Function procedurename Lib "libname" aliasname [(arglist)] As returntype [Public|Private] Declare Sub procedurename Lib "li
Public Declare Function ExtractIcon Lib "shell32.dll" Alias "ExtractIconA" (ByVal hInst As Long, ByVal lpszExeFileName As String, ByVal nIconIndex As Long) As Long 作用:判断一个可执行文件或DLL中是否有图标存在,并将其提取出来 返回值:Long,如成功,返回指向图标的句柄;如文件中不存在图标,则返回...
29.4.2 获取键盘信息 在VBA中，没有提供获取键盘状态的函数。在程序中若需要查询键盘状态，可编写代码调用API函数节器完成。1．GetKeyState函数 使用该函数可获取键盘锁定键的状态，函数原型如下：Public Declare Function GetKeyState Lib "user32" (ByVal nVirtKey As Long) As Integer 参数nVirtKe...

录段宏，总是”Sub MacroN()”。写临时测试，不是”Pirvate sub Test()”就是”Public Function Test()”。 “Private Sub Form_Load()”熟不熟？更别说模块和类模块了，甚至在立即窗口输入”Debug.Print Test”，它们都是函数。咦？不是说Function是函数，Sub是过程，Property是属性么？是的，在VB/VBA中...
Public Declare Function ExtractIcon Lib "shell32.dll" Alias "ExtractIconA" (ByVal hInst As Long, ByVal lpszExeFileName As String, ByVal nIconIndex As Long) As Long 函数名字还有一种情况,比如上面这句代码声明了两个函数名:ExtractIcon 和 "ExtractIconA",这是为了兼容。ExtractIcon才是API函数真正的...

Public Declare Function GetTickCount Lib "kernel32" () As Long #End If 需要大家注意的是参数较多，但不可少。这种引用建立后，VBA中将使用Windows的SetTimer和KillTimer函数。SetTimer指示Windows每隔NumberOfSeconds*1000毫秒执行一个指定过程，直到调用KillTimer。在此期间，应用程序是正常执行的，并且事件正常发生。2 ...
