>lcXML = FileToStr(cFullPathToXml)
>xmltocursor(lcXML, ...)

OK, the first line worked, put the file into the variable.
Second line, gives error, File name is to long. I renamed the xml file to myxml.xml

I even tried the following:
Created a test form with four controls on the form. Textbox, 3 command buttons.
the 1 command button will just call a GETFILE for an XML file and return the file to the textbox with the full path and filename, one to do the xmltocursor function and send it to a grid that is added on the fly, the other to exit.

This thing works like clock work in development. or even when I compile and run the exe on my development machine. But when I go to test box, I get the Exact same error.

  XML Parse Error:  No file was found. Line (0), Position (0). (null)

I don't know what the deal is.
