iLogic error handling on export PDF - "File in use"

Wowbagger2 — Wed, 05 Apr 2017 06:16:04 GMT

Hi,

I found this script in another thread (https://forums.autodesk.com/t5/inventor-forum/ilogic-rule-quot-auto-export-pdf-on-save-quot/td-p/5388693) to export/save a pdf from a drawing upon save. This works really good but I would like to add a error message if the file was unable to be saved/updated, most likely cause the PDF is open or in use somewhere. As of now the error that shows up is "(Exception from HRESULT: 0x80004005 (E_FAIL))" I would like to simply add a MessageBox instead. Happy if anyone could help me out.

Here's the script:

' Get the PDF translator Add-In.
Dim PDFAddIn As TranslatorAddIn
PDFAddIn = ThisApplication.ApplicationAddIns.ItemById("{0AC6FD96-2F4D-42CE-8BE0-8AEA580399E4}")
'Set a reference to the active document (the document to be published).
Dim oDocument As Document
oDocument = ThisApplication.ActiveDocument
Dim oContext As TranslationContext
oContext = ThisApplication.TransientObjects.CreateTranslationContext
oContext.Type = IOMechanismEnum.kFileBrowseIOMechanism
' Create a NameValueMap object
Dim oOptions As NameValueMap
oOptions = ThisApplication.TransientObjects.CreateNameValueMap
' Create a DataMedium object
Dim oDataMedium As DataMedium
oDataMedium = ThisApplication.TransientObjects.CreateDataMedium

' Check whether the translator has 'SaveCopyAs' options
If PDFAddIn.HasSaveCopyAsOptions(oDataMedium, oContext, oOptions) Then
'oOptions.Value("All_Color_AS_Black") = 1
oOptions.Value("Remove_Line_Weights") = 1
oOptions.Value("Vector_Resolution") = 400
oOptions.Value("Sheet_Range") = Inventor.PrintRangeEnum.kPrintAllSheets
'oOptions.Value("Custom_Begin_Sheet") = 2
'oOptions.Value("Custom_End_Sheet") = 4
End If

PDFDirectory = ThisDoc.Path
oFileName = ThisDoc.FileName(False) 'without extension

If ThisDoc.Path =  "" Then
MessageBox.Show("PDF file not created, click Save button again for PDF creation.", "iLogic")
Return 'exit rule
Else
oDataMedium.FileName = PDFDirectory & "\" & oFileName & ".PDF"
End If

'Publish document.
PDFAddIn.SaveCopyAs(oDocument, oContext, oOptions, oDataMedium)
'Launch the PDF file in whatever application Windows is set to open this document type with
'i = MessageBox.Show("Preview the PDF file?", "PDF Preview",MessageBoxButtons.YesNo,MessageBoxIcon.Question)
'If i = vbYes Then ThisDoc.Launch(oDataMedium.FileName)

On Error
MessageBox.Show("PDF not saved, file is in use. Please close the PDF-document and try again", "iLogic")

Thanks

/Fredrik

Hi @Wowbagger2

Before "publish document" with the "save copy as" command at the end of your code, you could add these lines :

SyntaxEditor Code Snippet

DocPDF = CreateObject("AcroExch.AVDoc")
'Check if PDF document exists
If System.IO.File.Exists(oDataMedium.FileName) Then
'Close it without saving
DocPDF.Open(oDataMedium.FileName,"...")
DocPDF.Close(True)
End If

Edit : I precise it will work only if the PDF document is open on your PC. If open by an other user...I think there is no way to solve this.

@ThomasB44

Thank you for that suggestion but I'm wondering, it seems to me pretty much the only error that can occur when trying to re save the PDF is that Inventor cannot access the file because it is already in use somewhere. Would it not be possible to have a MessageBox that pops up if the save failed for some (any!) reason?

Best,

Fredrik

Hi @Wowbagger2

Sure it would be possible, you can try these lines at the end of your code.

'Publish document.
Try
PDFAddIn.SaveCopyAs(oDocument, oContext, oOptions, oDataMedium)
Catch
'Fail to save, an error occurs
MessageBox.Show("PDF not saved, file is in use. Please close the PDF-document and try again", "iLogic")
End Try

Hi fredrik.carlsson,

Just change the last line to read as you see fit.

MessageBox.Show("PDF not saved.", "iLogic")

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Thank you all. I think this solution will be sufficient!
