There has been a few posts concerning the process of calling a Baan DLL function from VB code within a Windows application.

The attached zip file contains an example Excel spreadsheet and DLL that extracts Baan Text.

Baan DLL Function: (Library tudllolegwc)

VB Code:

Sub GetBaanText()
Dim BaanCompany As Long
Dim TextNumber As Long
Dim Line As Long
Dim StrText As String

    BaanCompany = Val(Cells(2, 1))  ' cell (row 2, col 1) is Company
    TextNumber = Val(Cells(2, 2))   ' cell (row 2, col 2) is Text Number
    Line = 1
    Cells(2, 3) = ""
    
    Call GetTextLines(BaanCompany, TextNumber, Line, StrText)
    Cells(2, 3) = StrText           ' cell (row 2, col 3) is returned Baan Text

End Sub


Sub GetTextLines(compnr As Long, TxtNum As Long, ByRef Line As Long, ByRef Text)
Dim LineCnt As String
Dim rText As String
Dim strTxtNum As String
Dim strCompany As String
Dim strLine As String

    strCompany = Format(compnr, "000")
    strTxtNum = Format(TxtNum, "000000000")
    strLine = Format(Line, "0000")
    cText = ""

    ' Loop until all lines of text are returned (4K bytes returned with each call)
    While Line > 0
        rText = String(4000, " ")
        dllname = "otudllolegwc"
        dllfunction = "tudll.olegwc.get.text.blks" & "("
        dllfunction = dllfunction & Chr(34) & strCompany & Chr(34) & ", "
        dllfunction = dllfunction & Chr(34) & strTxtNum & Chr(34) & ", "
        dllfunction = dllfunction & Chr(34) & strLine & Chr(34) & ", "
        dllfunction = dllfunction & Chr(34) & rText & Chr(34) & ")"
        Call SendtoBAAN(dllname, dllfunction)
                    
        ' Baan4
        strlen = Len(BaanObj.FunctionCall)
        tstr = BaanObj.FunctionCall

        ' Baan5
        'strlen = Len(BaanObj.ReturnCall)
        'tstr = BaanObj.ReturnCall

        Line = Val(Mid(tstr, 47, 10))
        tstr = RTrim(Mid(tstr, 53, strlen - 4))
        cText = cText & RTrim(Mid(tstr, 1, Len(tstr) - 2))
    Wend
        
    Text = cText
End
