To call Excel in VB, you need to open the "Reference" item in the "Project" menu of the VB programming environment and select the "MicrosoftExcel 11.0 object library" item in the project. Since your Excel version is different, the version number of this option is also different.
Because EXCEL organizes objects in a hierarchical structure, its object model contains many different object elements.
First layer: Application object, that is, Excel itself;
The second layer: workbooks object set, refers to the Excel workbook file
The third layer: the worksheets object set, which represents a worksheet in Excel;
The fourth layer: Cells and Range objects, pointing to cells in the Excel worksheet.
Dim xlapp As Excel.Application 'Excel object
Dim xlbook As Excel.Workbook 'Workbook
Dim xlsheet As Excel.Worksheet 'Worksheet
Set xlapp = CreateObject("Excel.Application") 'Create EXCEL object
Set xlbook = xlapp.Workbooks.Open("D:\data.xls") 'Open the existing data.xls workbook file
xlapp.Visible = True 'Set the EXCEL object to be visible (or invisible)
Set xlsheet = xlbook.Worksheets(1) 'Set active worksheet''
''~~~The first sheet of the current workbook, you can also change it to "table name" such as "Sheet1"
[Define the array part yourself]
Assign the value in a cell in the table to a variable, such as an element in an array
arr(1,1)=xlsheet.Range("B2").Value
……
Last close:
xlbook.Close
xlapp.quit
Then set the three objects into nothing
Use database query method
Read it and put it into a two-dimensional array
Dim cnn2 As New ADODB.Connection
Dim rs2 As New ADODB.Recordset
cnn2.Open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=" & Text1.Text & ";Extended"
rs2.Open "Select name, gender From [sheet1$]", cnn2, adOpenKeyset, adLockOptimistic
i=0
s = rs2.ields.Item(0).Value 'Read the name and gender in sheet1
If IsNull(s) Then Exit Do
a(i)=rs2.fields.Item(0).Value 'Name
b(i)=rs2.Fields.Item(1).Value 'Gender
i=i 1
rs2.MoveNext
Loop
Set rs2 = Nothing
Set cnn2 = Nothing
Code to read cell A2: (The data is in the variable R, MICROSOFT EXCEL OBJECT LIBRARY needs to be quoted before the project)
Private excelApp As excel.Application
Private Sub Command2_Click()
Set excelApp = New excel.Application
excelApp.Visible = True
excelApp.Workbooks.Open FileName:="C:\student.xls"
excelApp.Range("A2").Select
r = excelApp.ActiveCell.FormulaR1C1
Debug.Print r
excelApp.Quit
Set excelApp = Nothing
End Sub
'If you don't want everyone to see the EXCEL interface, just remove excelApp.Visible = True.
