Exit Function示例: vba Function SomeFunction() As String ' 执行一些操作 ' ... ' 如果满足某个条件,则提前退出并返回一个值 If someCondition Then SomeFunction = "Early Return" Exit Function End If ' 其他操作 ' ... SomeFunction = "Normal Return" End Function 使用错误处理机制: 如果需要在特...
VBA中有时要判断文件或文件夹是否存在，为打开文件作准备，这里采用错误机制来判断 代码如下：Function 文件或文件夹是否存在(全路径 As String) As Boolean On Error GoTo EarlyExit If Not Dir(全路径, vbDirectory) = vbNullString Then 文件或文件夹是否存在 = True End If Exit Function EarlyExi...
Function CountFiles(strDirectory As String, Optional strExt As String = "*.*") As Double Dim objFso As Object Dim objFiles As Object Dim objFile As Object '设置错误处理 On Error GoTo EarlyExit '创建对象以获取文件夹中的文件数 Set objFso = CreateObject("Scripting.FileSystemObject") Set obj...
EarlyExit:On Error GoTo 0 End Function 给你个简单的例子Sub test()Range("a1") = test2(3, 4)End SubFunction test2(x As Integer, y As Integer)test2 = x + yEnd Function运行test过程，A1单元格就会是7。function的参数必须要有值传递的
Sub EarlyBinding() Dim objExcel As Excel.Application Set objExcel = New Excel.Application With objExcel .Visible = True .Workbooks.Add .Range("A1") = "Hello World" End With End Sub 2. 使用CreateObject创建Excel实例 Sub LateBinding() ...
本自定义函数由于使用了第三方库,使用前需要做Early Binding:即在VBE编辑器中,选择菜单栏中的Tool — Reference: 弹出如下图的对话框后,选择Microsoft VBSscript Regular Expression 5.5,打钩,点OK。 最后按Ctrl+S保存文件,注意在保存对话框中,文件类型需要选择“Excel启动宏的工作簿(*.xlsm)”,如下图 ...
给个小例子 Public Function FileFolderExists(strFullPath As String) As Boolean On Error GoTo EarlyExit If Not Dir(strFullPath, vbDirectory) = vbNullString Then FileFolderExists = True EarlyExit:On Error GoTo 0 End Function
Function getCmdlineOutput2(cmd As String) 'requires Reference: C:\Windows\System32\FM20.DLL (MS Forms 2.0) [Early Bound] Dim objClipboard As DataObject, strOrigClipbrd As Variant Set objClipboard = New MSForms.DataObject 'create clipboard object ...
4.判断指定文件或者文件夹是否存在 Public Function FileFolderExists(strFullPath As String) As Boolean On Error GoTo EarlyExit If Not Dir(strFullPath, vbDirectory) = vbNullString Then FileFolderExists = True EarlyExit: On Error GoTo 0 End Function...
