InfoPath Dev

Hi I want to set expiry date to info path files through C#.

This is the code which I am using but its not working.Please tell me the problem.

Microsoft.Office.Interop.InfoPath.ApplicationClass oWord = new Microsoft.Office.Interop.InfoPath.ApplicationClass();

oDoc.Permission.Add(username, exp, dtExpireDate);

oDoc = null;

oWord = null;

Give us a bit more details on what you are trying to accomplish.

You want to no longer open new forms and to close itself immediately if it is past a certain age?  The xsn would only work with new forms, do you want existing forms (xml files) to be affected?

I would think having a system process that would check a files date or age and then restrict access would be more effective.

Hi  Clay

  Thanks for your reply.

 actually I only want to set rights & expiry date to an existing files only.No new forms.

for this I changed my code a little bit but its still giving some problem.The problem area is line

 oDoc1 = (_XDocument3)oWord.XDocuments.Open(infoFileName, (int)XdDocumentVersionMode.xdCanOpenInReadOnlyMode); 

Its throwing an exception here saying "{"InfoPath cannot open the following file: D:\\Test\\2.xsn.\nThe file is not a valid XML file.\n\nThe form contains XML that cannot be parsed:\nAn invalid character was found in text content.\r\n\nLine 1, Position 5\nMSCF\n----^\n"}"

 This same code is working fine for excel,word & powerpoint files.

Please tell me where I am wrong.I am pasting my latest code here.

object infoFileName = "D:\\Test\\2.xsn";

Microsoft.Office.Interop.InfoPath._XDocument3 oDoc1;

oDoc1 = (_XDocument3)oWord.XDocuments.Open(infoFileName, (int)XdDocumentVersionMode.xdCanOpenInReadOnlyMode);

oDoc1.Permission.Add( username, MsoPermission.msoPermissionRead, dtExpireDate);
