Nā laʻana o Excel Macros i kākau ʻia me VBA

Ua kākau ʻia nā hiʻohiʻona macro Excel maʻalahi me ka VBA 

Manaʻo manawa heluhelu: 3 minuke

Hoʻohālike VBA me ka hoʻohana ʻana i ka Array

Heluhelu ke kaʻina hana ma lalo nei i nā waiwai mai nā cell i ke kolamu A o ka pepa hana hana, a hiki i ka wā e hālāwai ai me kahi cell blank. Mālama ʻia nā waiwai i loko o kahi array. Hōʻike kēia hiʻohiʻona macro Excel maʻalahi i ka hoʻohana ʻana o:

• Nā ʻōlelo hoʻohālikelike;
• Nā hoʻonohonoho ikaika;
• He pōʻaiapuni Do Until;
• E nānā i nā pūnaewele ma ka pepa hana Excel o kēia manawa;
• ʻO ka hana VBA Ubound builtin (ʻo ia ka mea e hoʻihoʻi i ka helu kiʻekiʻe o kahi array).

' Sub procedure store values in Column A of the active Worksheet
' into an array
Sub GetCellValues()
Dim iRow As Integer            ' stores the current row number
Dim dCellValues() As Double  ' array to store the cell values
iRow = 1
ReDim dCellValues(1 To 10)
' Do Until loop to extract the value of each cell in column A
' of the active Worksheet, as long as the cell is not blank
Do Until IsEmpty(Cells(iRow, 1))
   ' Check that the dCellValues array is big enough
   ' If not, use ReDim to increase the size of the array by 10
   If UBound(dCellValues) < iRow Then
      ReDim Preserve dCellValues(1 To iRow + 9)
   End If
   ' Store the current cell in the CellValues array
   dCellValues(iRow) = Cells(iRow, 1).Value
   iRow = iRow + 1
Loop
End Sub

Mālama ke kaʻina hana i nā koina ma ke kolamu A o ka pepa hana i loko o kahi ʻano, e hoʻomaopopo i kēia:

• Ka pōʻaiapuni Do Until unuhi i nā waiwai o kēlā me kēia cell i ke kolamu A o ka pepa hana hana, me ka nānā ʻole ʻana i nā cell blank
• ʻO ke kūlana "If UBound(dCellValues) < iRow" e nānā i ka nui o ka dCellValues ​​​​array e paʻa i ka ʻike, inā ʻaʻole, e hoʻohana iā ReDim e hoʻonui i ka nui o ka array e 10
• ʻO ka hope, hoʻonaʻauao​​dCellValues(iRow) = Cells(iRow, 1).Value” Mālama i ke kelepona o kēia manawa i ka pūʻulu CellValues

Hoʻohālike VBA me nā hana makemakika

Heluhelu ke kaʻina hana ma lalo nei i nā waiwai mai ka kolamu A o ka pepa haʻawina i kapa ʻia ʻo "Sheet2" a hana i nā hana helu ma nā waiwai. Paʻi ʻia nā waiwai i loaʻa ma ka kolamu A o ka pepa hana hana o kēia manawa.

Hōʻike kēia macro:

• Nā ʻōlelo hoʻohālikelike;
• Nā mea Excel (ʻokoʻa, hoʻohana i ka huaʻōlelo Set a pehea e komo ai i ka mea 'Columns' mai ka mea 'Sheets');
• He pōʻaiapuni Do Until;
• E kiʻi i nā pepa haʻawina a me nā pae kelepona ma ka puke hana Excel o kēia manawa.

' Sub procedure to loop through the values in Column A of the Worksheet
' "Sheet2", perform arithmetic operations on each value, and write the
' result into Column A of the current Active Worksheet ("Sheet1")
Sub Transfer_ColA()
Dim i As Integer
Dim Col As Range
Dim dVal As Double
' Set the variable 'Col' to be Column A of Sheet 2
Set Col = Sheets("Sheet2").Columns("A")
i = 1
' Loop through each cell of the column 'Col' until
' a blank cell is encountered
Do Until IsEmpty(Col.Cells(i))
   ' Apply arithmetic operations to the value of the current cell
   dVal = Col.Cells(i).Value * 2 + 1
   ' The command below copies the result into Column A
   ' of the current Active Worksheet - no need to specify
   ' the Worksheet name as it is the active Worksheet.
   Cells(i, 1) = dVal
   i = i + 1
Loop
End Sub

VBA laʻana me ka hoʻopaʻa lā hoʻololi

E kākau mākou i kahi macro VBA maʻalahi e ʻā ana i ka wā e hōʻano hou ʻia kahi kelepona ma kahi kikoʻī o kā mākou pepa. Inā makemake ʻoe e hahai i nā loli ma ke kolamu B (B4 a i ka B11) a e hoʻopaʻa i ka lā a me ka manawa o ka hoʻololi ʻana ma ke kolamu A.
E hoomau kakou penei:

• I ka papa ʻaina Developer kaomi ma ke koho "Visual Basic” e wehe i ka mea hoʻoponopono VBA.
• Ma ka hoʻoponopono VBA, kaomi pālua i ka mea hoʻoponopono code pili iā Sheet2.
• E koho i ka Pepa Haʻawina mai ka ʻaoʻao ʻākau (a hema paha) a koho i ke koho Hoʻololi.
• Hoʻohui i ka code VBA:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target, Range("B1:B10")) Is Nothing Then
        Target.Range("A1:A1").Value = Now
    End If
End Sub

E mālama i ka puke hana me nā macros i hoʻohana ʻia (no ka laʻana, he faila .xlsm).

I kēia manawa, i kēlā me kēia manawa mākou e hōʻano hou i kahi kelepona ma ke kolamu B (mai ka lālani 1 a hiki i ka lālani 10), e hōʻike ʻokoʻa ka cell i ka kolamu A i ka lā a me ka manawa o kēia manawa.
