I am getting the above error while trying to export the excel 2007(xlsx) format workbook to pdf. The workbook contains only one sheet and I have Ms Office 2007 installed on my windows 7 PC. Here is the stacktrace
at Microsoft.Office.Interop.Excel.WorkbookClass.ExportAsFixedFormat(XlFixedFormatType Type, Object Filename, Object Quality, Object IncludeDocProperties, Object IgnorePrintAreas, Object From, Object To, Object OpenAfterPublish, Object FixedFormatExtClassPtr)
at schoolwisereportprint.converttopdf() in
C:\Users\username\Desktop\Dpp2012New\schoolwisereportprint.aspx.vb:line 33
at schoolwisereportprint.Button1_Click(Object sender, EventArgs e) in C:\Users\username\Desktop\Dpp2012New\schoolwisereportprint.aspx.vb:line 158
Here is my converttopdf() function:
Public Sub converttopdf()
Dim fileName As String = Server.MapPath("rahulserver/pdfreprt.xlsx")
Dim xlsApp = New Microsoft.Office.Interop.Excel.Application
xlsApp.ScreenUpdating = False
Dim xlsBook As Microsoft.Office.Interop.Excel.Workbook
Dim paramExportFormat As XlFixedFormatType = XlFixedFormatType.xlTypePDF
Dim paramExportQuality As XlFixedFormatQuality = XlFixedFormatQuality.xlQualityStandard
Dim paramOpenAfterPublish As Boolean = False
Dim paramIncludeDocProps As Boolean = True
Dim paramIgnorePrintAreas As Boolean = True
Dim paramFromPage As Object = Type.Missing
Dim paramToPage As Object = Type.Missing
xlsBook = xlsApp.Workbooks.Open(fileName, UpdateLinks:=False, ReadOnly:=False)
xlsBook.ExportAsFixedFormat(paramExportFormat, "rahulserver/pdfreprt" & ".pdf", paramExportQuality, paramIncludeDocProps, paramIgnorePrintAreas,paramFromPage, paramToPage, paramOpenAfterPublish)
xlsBook.Close(SaveChanges:=False)
xlsApp.Quit()
MsgBox("successfully converted to pdf!")
End Sub
Even changing paramFromPage and paramToPage to 1 and 1 respectively does not help. I have already spent a whole day troubleshooting this error but could not find a way. Now I look upon SO to get me out of this...
