Sharepoint SPFile.Convert Infopath to HTML

Question

i have the conversion code for converting from infopath to HTML

Guid id;
var conversionResults = newItem.Convert(new Guid("853d58f5-13c3-46f8-8b81-3ca4abcad7b3"), Path.GetFileNameWithoutExtension(newItem.Name), null, "Microsoft.Office.InfoPath.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c", "Microsoft.Office.InfoPath.Server.DocumentConversion", 1, String.Empty, false, true, out id);

Which i got from using the msdn convert http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spfile.convert.aspx and general documentation around the subject but whenever i try to run it i get the exception

Could not load type 'Microsoft.Office.InfoPath.Server.DocumentConversion' from assembly 'Microsoft.Office.InfoPath.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.

   at RMS.FormServices.ConvertInfopathToASPX(String infopathFile, String fileNamingbasedon) in C:\Documents and Settings\UN\Source Control\Project\FormServices.asmx.cs:line 243

If i change it to

Guid id;
var conversionResults = newItem.Convert(new Guid("853d58f5-13c3-46f8-8b81-3ca4abcad7b3"), Path.GetFileNameWithoutExtension(newItem.Name), null, "Microsoft.Office.InfoPath.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c", "Microsoft.Office.InfoPath.Server.DocumentConversion", 1, String.Empty, false, false, out id);

it returns success however if i then try

var converted = newItem.GetConvertedFile(id);

it throws a exception and if i try

while (true)
{
    var state = newItem.GetConversionState(new Guid("853d58f5-13c3-46f8-8b81-3ca4abcad7b3"), id);
    if (state == SPFileConversionState.Completed)
        break;
}

then state hits pending, then after a while available state and never changes after that, ive been trying to get this code working for ages and any help would be appreciated

just as a side note, the convert Infopath to HTML is enabled on the sharepoint server, its all configured and it works from sharepoint (very slowly though) i just cant get it working from the code.

Edit: Some futher information after looking at the logs and with the conversion code looking like

var conversionResults = newItem.Convert(new Guid("853d58f5-13c3-46f8-8b81-3ca4abcad7b3"), Path.GetFileNameWithoutExtension(newItem.Name), null, null, null, 1, String.Empty, false, true, out id);

the conversion fails and the following shows up in the logs

08/02/2011 14:53:42.83 Microsoft.Office.Server.Convers (0x04FC) 0x06BC Document Conversions Launcher Service 7jg8 Verbose Calling LoadBalancer.RegisterLauncher

Edit 2: i changed the max size for the converter and it is running a lot faster now from both code and sharepoint but the conversion code is still not working and just comming up as failure. the Log for the converter can be found here (everything from the start of the convert code till the end)

Answer 1

I think the root of the problem is your assembly reference is for the SP2007 Forms Server (i.e. Version=12.0.0.0). I'm not sure there is even a 2010 equivalent, as the DocumentConversion class does not exist in Microsoft.Office.InfoPath.Server, Version=14.0.0.0

You could try not specifying the Assembly and Class (...they are optional and I think primarily used to specify a pre or post conversion handler)...the Conversion Launcher should be able to act on the GUID of the InfoPath Transformer (...which is correct).

So change the Assembly and Class references to null and see if that does the trick.

UPDATE: I set this up in one of my dev environments and it worked without the Assembly or Class arguments:

SPFileConversionResult result = file.Convert(new Guid("853d58f5-13c3-46f8-8b81-3ca4abcad7b3"), "test123", null, null, null, 1, String.Empty, false, true, out id);

One other to check is make sure you have enabled document conversion on your web app: http://technet.microsoft.com/en-us/library/cc770243.aspx. I suspect you have already done this because I don't think you'd be seeing the error, but putting it out there just in case.
