如果我在Excel中有以下3列布局...

column1  column2    column3
one      three      info about three

two      one        info about one

three    two        info about two

four     six        info about six

         seven      info about seven

         eight      info about eight

...如何删除或隐藏或删除第2列中没有第1列值的任何行？

我的最终结果应该是这样的......

column1  column2    column3
one      

two      one        info about one

three    two        info about two

four     

我在循环幻灯片中的形状的行中出现类型不匹配13错误.我可以看到它oSh是Nothing,但如果我.Count的形状,幻灯片中有很多形状.这有什么意义？

简要代码:

Dim oPP As PowerPoint.Presentation
Dim oS As Slide
Dim oSh As Shape
For Each oS In oPP.Slides
    For Each oSh In oS.Shapes '<-- this line is the error line
        On Error Resume Next
        If oSh.Type = 14 _
                Or oSh.Type = 1 Then
            'do stuff            
        End If
        On Error GoTo 0
    Next oSh
Next oS

完整代码:

Sub PPLateBinding()
    Dim pathString As String
    'no reference required
    Dim PowerPointApplication As PowerPoint.Application
    Dim oPP As …

我试图通过从私有范围内的函数中剥离参数来清理代码,如下所示:

Function complicatedFunction(x as Double, param1 as Double, param2 as Double)
    ...
End Function

Function mainActionHappensHere(L as Double, U as Double ...)
    Function cleaner(x)
        cleaner = complicatedFunction(x, L, U)
    End Function
    ...
    cleaner(x)                       'Many calls to this function
    ...
End Function

这可能吗？编译器抱怨"预期结束函数",因为我在结束外部函数之前开始执行函数.谷歌没有帮助:( PS我不能在mainActionHappensHere()之外定义cleaner(),因为那时正确的L和U不会被传递到它.

我目前有两个数组,每个数组包含范围.你将如何获得这两个数组的交集.换句话说,我想得到一个范围数组,它只包含两个原始数组中包含的范围.我尝试过.Intersect,但是在我学习的时候这对数组不起作用.

array1 :(范围("A1"),范围("B1"),范围("C1"))array2 :(范围("A1"),范围("A2"),范围("A3"))

结果:(范围("A1"))

我有这两个合集

var materials = new List<Models.Material>();
materials.Add(new Models.Material { Number = 111, Value = null });
materials.Add(new Models.Material { Number = 222, Value = null });

var db_materials = new List<Models.DB_Material>();
db_materials.Add(new Models.DB_Material { Number = 111, ValueColumn = 10});
db_materials.Add(new Models.DB_Material { Number = 222, ValueColumn = 20 });
db_materials.Add(new Models.DB_Material { Number = 333, ValueColumn = 30 });
db_materials.Add(new Models.DB_Material { Number = 444, ValueColumn = 40 });

我需要使用db_materials集合中的ValueColumn更新材料集合中的所有Value属性。
