Have you ever wondered how to read and display data from Excel to Listview in VB6? Learning this process can be complex but with our step-by-step guide, we can simplify it for you.
Step-by-step guide on how to read and display data from Excel to Listview in VB6
The first step to display data from Excel to Listview in VB6 is to create a new project. Then, follow the steps below:
Step 1: Create a new form
To create a new form, click on File then select New Project. The New Project dialog box will appear, select Standard EXE as your project type and click on Open.
Once you have created the new project, select Form1.vb from the Solution Explorer window. Then, select Form1.vb designer view. Add a Listview control to your form.
Step 2: Add a module for the code
Add a new module to your project by clicking on the Project menu and then selecting Add Module.
Enter the following code in the module:
“`vb
Public mobjConn As ADODB.Connection
Public mobjRS As ADODB.Recordset
“`
Step 3: Create the connection string
Create a connection to the Excel file by adding the following code:
“`vb
Public Function OpenDB(ByVal pstrConn As String) As Boolean
On Error GoTo ErrHandler
Set mobjConn = New ADODB.Connection
mobjConn.ConnectionString = pstrConn
mobjConn.CursorLocation = adUseClient
mobjConn.Open
OpenDB = True
Exit Function
ErrHandler:
OpenDB = False
End Function
Public Function CloseDB() As Boolean
On Error GoTo ErrHandler
If Not mobjRS Is Nothing Then mobjRS.Close
If Not mobjConn Is Nothing Then
If mobjConn.State = adStateOpen Then
mobjConn.Close
End If
End If
Set mobjRS = Nothing
Set mobjConn = Nothing
CloseDB = True
Exit Function
ErrHandler:
CloseDB = False
End Function
“`
Step 4: Connect to the Excel file
Next, connect to the Excel file by adding the following code:
“`vb
Public Function LoadData(ByVal pstrFile As String, ByVal pstrSheet As String) As Boolean
On Error GoTo ErrHandler
LoadData = False
If CloseDB = False Then GoTo ErrHandler
If OpenDB(“Provider=Microsoft.Jet.OLEDB.4.0;Data Source=” & pstrFile & “;Extended Properties=””Excel 8.0;HDR=YES;IMEX=1″”;”) = False Then GoTo ErrHandler
Set mobjRS = New ADODB.Recordset
With mobjRS
.CursorLocation = adUseClient
.CursorType = adOpenStatic
.LockType = adLockReadOnly
.Open “SELECT * FROM [” & pstrSheet & “$];”, mobjConn
End With
LoadData = True
Exit Function
ErrHandler:
MsgBox “Error: ” & Err.Description
End Function
“`
Step 5: Populate the Listview with data
After connecting to the Excel file, you can now populate the Listview with the data by adding the following code:
“`vb
Public Sub PopulateListview()
On Error GoTo ErrHandler
List1.ColumnHeaders.Clear
List1.ListItems.Clear
If mobjRS.RecordCount > 0 Then
With List1.ColumnHeaders
For i = 0 To mobjRS.Fields.Count – 1
.Add , , mobjRS.Fields(i).Name
Next i
End With
Do While Not mobjRS.EOF
Set item = List1.ListItems.Add(, , mobjRS(0))
For i = 1 To mobjRS.Fields.Count – 1
item.ListSubItems.Add , , mobjRS(i)
Next i
mobjRS.MoveNext
Loop
End If
Exit Sub
ErrHandler:
MsgBox “Error: ” & Err.Description
End Sub
“`
Step 6: Display the Listview
To display the Listview, add the following code to the Form_Load event:
“`vb
Private Sub Form_Load()
Dim strFile As String
Dim strSheet As String
strFile = “C:\MyExcelFile.xls”
strSheet = “Sheet1”
If LoadData(strFile, strSheet) Then
PopulateListview
End If
End Sub
“`
Now, run the program and you will be able to read and display data from Excel to Listview in VB6!
FAQs
What if I want to display data from a different sheet in the same Excel file?
To display data from a different sheet in the same Excel file, simply change the value of strSheet variable in the Form_Load event to the name of the sheet you want to display.
What if my Excel file has a different extension?
If your Excel file has a different extension (e.g. .xlsx), simply change the connection string in the LoadData function to:
“`vb
“Provider=Microsoft.ACE.OLEDB.12.0;Data Source=” & pstrFile & “;Extended Properties=””Excel 12.0 Xml;HDR=YES;IMEX=1″”;”
“`
