#1

hi there

we have password protected .xls file and want to convert into pdf password protected file.

as we do :

we have function that return as byte[]

start function

workbook = New Aspose.Cells.Workbook

'workbook.Open(Request.PhysicalApplicationPath & strInputFilename)

workbook.Open(strInputFilename, Aspose.Cells.FileFormatType.Excel2003, "007")

'ExceltoPDF(workbook, strOutputFilename)

strFileName = Path.GetFileName(strInputFilename)

strFileName = strFileName.Substring(0, strFileName.LastIndexOf(".")) & ".xml"

workbook.Save(strServerPath & strFileName, Aspose.Cells.FileFormatType.AsposePdf)

pdf.BindXML(strServerPath & strFileName, Nothing)

pdf.Security = New Aspose.Pdf.Security

pdf.Security.UserPassword = "007"

'remove the temporary xml file

File.Delete(strServerPath & strFileName)

Return pdf.GetBuffer()

end function

on pdf.GetBuffer() we get exception : object reference not set to an instance of an object.

help me to find the solution on this issue.

hi,

That is working fine. There is one more issue Like. if we want open excel file . after open we want to check it is password protectet or not.

On the base of this we want to do some thing. here is code :

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

workbook.Open("c:\\templatefile.xls");

if (workbook.IsProtected)

{

//here goes your code for protected file

}else

{

//here goes your code for not protectet file

}

waiting for your reply

regards

Hi,

Well I am afraid Aspose.Cells does not support to check whether the file is open/modify protected. You may only use Workbook.IsProtected to check whether workbook is protected using windows/structure lock options (In MS Excel check menu options Tool--> Protection --> Protect Workbook).

Thank you.

We have supported setting encryption and protection settings on the generated pdf file

Sample code:

workbook.Open("test.xls");

PdfSaveOptions saveOption = new PdfSaveOptions();

saveOption.SecurityOptions = new Rendering.PdfSecurity.PdfSecuritySettings();

saveOption.SecurityOptions.UserPassword = "user";

saveOption.SecurityOptions.OwnerPassword = "owner";

saveOption.SecurityOptions.ExtractContentPermission = false;

saveOption.SecurityOptions.PrintPermission = false;

workbook.Save("test.pdf",saveOption);

Thanks!
