Excel programming (C# + VBA) Part 1

Excel programming (C# + VBA)

Here is the secario of a full process of solution to use excel to submit information.

•    Clarify the requirement and create the Excel template (VBA)
• Generate an Excel template to fill with source data (C#)
• Download the template from web site (C# + ASP.NET)
• Fill in the template and verified the data via VBA (VBA)
• Upload the template (Web) (ASP.NET)
• Import data in Excel Template to database (C#)

1.      Setp 1 Create the Excel Template based on requirement

a.       Clarify the requirement

b.      Create hidden template sheet

                                                               i.      Clarify the data type in each cell, fill in type (user input/list validation or a pop form) and the lock property.

c.       Create hidden data source sheet

                                                               i.      Clarify the source data in each column

                                                             ii.      Create named range for list validation (If the data is already known)

d.      Create Summary, Filling Sheet

                                                               i.      Set the layout, add validation button and Add new button

e.      VBA programming to add list validation or auto-filling 

    rng.Validation.Add xlValidateList, xlValidAlertStop, xlBetween, "=SpecialOfferType"
    rng.Validation.IgnoreBlank = True
    rng.Validation.InCellDropdown = True
    

f.        VBA programming to select data in pop form

            With frmChoose
                .CCodeColumn = "AB"
                .CNameColumn = "B"
                .CRow = Target.Row
                .CCodeSourceColumn = "B"
                .CNameSourceColumn = "C"
                .CKeyWords = Me.Cells(iRow, iColumn).Text
                .Caption = Me.Cells(iRow, iColumn - 1)
                Set .CWorksheet = Application.ActiveSheet
                Set .CSourceWorksheet = sourceSheet
                .Show
            End With

In frmChoose, when the Ok button is clicked:

        CWorksheet.Unprotect Password
        
        n = 2
        If (CSourceWorksheet Is Nothing) Then
            name = wsDataSource.Range(CNameSourceColumn & n).Text
        Else
            name = CSourceWorksheet.Range(CNameSourceColumn & n).Text
        End If
        
        While (name <> "")
            If name = lstSelected.List(lstSelected.ListIndex) Then
                If (CSourceWorksheet Is Nothing) Then
                    code = wsDataSource.Range(CCodeSourceColumn & n).Text
                Else
                    code = CSourceWorksheet.Range(CCodeSourceColumn & n).Text
                End If
            End If
            
            n = n + 1
            If (CSourceWorksheet Is Nothing) Then
                name = wsDataSource.Range(CNameSourceColumn & n).Text
            Else
                name = CSourceWorksheet.Range(CNameSourceColumn & n).Text
            End If
        Wend
        
        If (CNameColumn <> "") Then
            CWorksheet.Range(CNameColumn & CRow).Value2 = lstSelected.List(lstSelected.ListIndex)
        End If
        
        If (CCodeColumn <> "") Then
            CWorksheet.Range(CCodeColumn & CRow).Value2 = code
        End If
        
        CWorksheet.Protect Password
        

g.       VBA programming to validate the data filled in every sheets

          If Not CheckDateType(ws.Cells(i, 2).Value) Then
                bCheck = False
                MsgBox ws.Cells(i, 1).Value & "ÄÚÊäÈëµÄ²»ÊÇÓÐЧʱ¼ä"
                ws.Activate
                ws.Cells(i, 2).Select
                Exit Sub
          End If
.....

Function CheckNumberic(sourceString As String) As Boolean
    Dim bOk As Boolean
    bOk = True
    If sourceString <> "" And Not IsNumeric(sourceString) Then
        bOk = False
    End If
    
    CheckNumberic = bOk
End Function


Function CheckDateType(sourceString As String) As Boolean
    Dim bOk As Boolean
    bOk = False
    If sourceString <> "" And IsDate(sourceString) Then
        bOk = True
    End If
    
    CheckDateType = bOk
    
End Function
