Powershell: is there a limit to the number of output file types I can have?

Question

I've got a Powershell (2.0) script that uses Microsoft.Office.Interop.Word.WdSaveFormat to recursively open a series of html files in Word, then save as Word and Text using the wdFormatDocument and wdFormatDOSText parameters, respectively. The script contains a separate function for each document type.

Yesterday, the requirements changed, and I now need to output an RTF document as well. I added the $saveFormatRTF variable

$saveFormatDoc = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatDocument"); 
$saveFormatTxt = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatDOSText"); 
$saveFormatRTF = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatRTF");  

and got the following errors.

Running the script converting JUST to Word and Text works fine. Running the RTF by itself it just fine. However, anytime I combine RTF in a script with other output formats, ALL output formats referenced in the script come up as "not found". Does RTF need to be exported on its own? Is there a limit to how many output file types I can have in one script (they're all separate functions, though)? Is there some parameter I'm not setting?

I have verified that the member names for output are correct, and I've scanned MSDN for clues, but can't find anything that would cause this behavior, especially the unpredictable results when adding RTF to the mix. Any ideas?

Answer 1

I did some further testing, a few days later I was able to convert as expected with no difficulties. I also tested converting to every format listed here with a single script...and except for some funky output formatting on special characters, everything worked great.

So, I'm guessing there's no limit, and my testing seems to bear out that theory.
