Today, we will discuss how to read and display data from Excel to ListView using VB6. But before we dive deeper into this topic, let’s take a look at what a CSV file is and how to open it in Excel without any mess. CSV stands for Comma Separated Values, and it is a file format that is used to store tabular data. It is similar to Excel, but the main difference is that it stores data in a simpler plain text format.
How to Open CSV File in Excel
If you have a CSV file that you want to open in Excel, follow these steps:
Step 1: Launch Excel and select the “Open” command from the “File” menu or use “Ctrl+O” shortcut key.
Step 2: In the “Open” dialog box, navigate to the folder that contains the CSV file you wish to open.
Step 3: Select “Text Files ” from the “Files of Type” dropdown list.
Step 4: Select the CSV file you want to open and click on the “Import” button.
Step 5: In the “Text Import Wizard – Step 1 of 3 ” dialog box, select “Delimited” option and click on the “Next” button.
Step 6: In the “Text Import Wizard – Step 2 of 3” dialog box, select the delimiter that separates the fields in the CSV file. By default, Comma (,) is the delimiter.
Step 7: In the “Text Import Wizard – Step 3 of 3” dialog box, select the column data format. If you have any columns containing text or date data, be sure to specify the correct data format for the column. Otherwise, Excel may not recognize the data correctly.
Step 8: Click the “Finish” button, and Excel will import and display the CSV data in the new worksheet.
Now that you know how to open a CSV file in Excel, let’s get back to our main topic.
How to Read and Display Data From Excel to ListView Using VB6
Before we start, you need to make sure that you have Microsoft Excel installed on your computer and that you have a basic understanding of VB6 programming.
Step 1: Open VB6, create a new project, and add a ListView control to your form.
Step 2: Double-click the ListView control to open the code window.
Step 3: Let’s create a subroutine to read the data from the Excel file:
Sub ReadData()
Dim xlApp As Object
Dim xlBook As Object
Dim xlSheet As Object
Dim iRow As Integer
Dim iCol As Integer
Dim iItem As Integer
Set xlApp = CreateObject("Excel.Application")
Set xlBook = xlApp.Workbooks.Open("C:\Data.xls")
Set xlSheet = xlBook.Worksheets("Sheet1")
iRow = 1
Do Until xlSheet.Cells(iRow, 1).Value = ""
With lvwData
iItem = .ListItems.Add(Text:=xlSheet.Cells(iRow, 1).Value)
For iCol = 2 To 4
.ListItems(iItem).SubItems(iCol - 2) = xlSheet.Cells(iRow, iCol).Value
Next iCol
End With
iRow = iRow + 1
Loop
xlBook.Close False
xlApp.Quit
End Sub
Step 4: Call the subroutine from the Form_Load event.
Private Sub Form_Load()
ReadData
End Sub
Step 5: Let’s add a few images to our ListView:
Sub ReadData()
Dim xlApp As Object
Dim xlBook As Object
Dim xlSheet As Object
Dim iRow As Integer
Dim iCol As Integer
Dim iItem As Integer
Dim sImageFile As String
Set xlApp = CreateObject("Excel.Application")
Set xlBook = xlApp.Workbooks.Open("C:\Data.xls")
Set xlSheet = xlBook.Worksheets("Sheet1")
iRow = 1
Do Until xlSheet.Cells(iRow, 1).Value = ""
With lvwData
iItem = .ListItems.Add(Text:=xlSheet.Cells(iRow, 1).Value)
For iCol = 2 To 4
.ListItems(iItem).SubItems(iCol - 2) = xlSheet.Cells(iRow, iCol).Value
Next iCol
sImageFile = "C:\Images\" & xlSheet.Cells(iRow, 5).Value
If Len(Dir(sImageFile)) > 0 Then
.ListItems(iItem).SmallIcon = LoadPicture(sImageFile)
End If
End With
iRow = iRow + 1
Loop
xlBook.Close False
xlApp.Quit
End Sub
Step 6: Compile and run the application.
Congratulations! You have successfully learned how to read and display data from Excel to ListView using VB6.
FAQ:
Q1: Can I use Microsoft Excel to write code in VB6?
A: No, they are two separate programs. Excel is a spreadsheet application used for data analysis and manipulation, while VB6 is a programming language used for software development.
Q2: What is a ListView control in VB6?
A: A ListView control is a versatile control that displays a list of items with optional icons, in a variety of formats. The user can select one or more items from the list, depending on the setup of the control.
