properties - Problem using EnvDTE.Property.set_Value to set ProjectItem FullPath Property -

i have visual studio project wizard attempts configure vc# project override fullpath property selected files template.

the following code used within function

public void projectfinishedgenerating(project project)

string path = "some file name"; project.projectitems.item("some file").properties.item("fullpath").value = path; 

system.reflection.targetparametercountexception: invalid number of parameters. (exception hresult: 0x8002000e (disp_e_badparamcount)) @ envdte.property.set_value(object lppvreturn)

i know have valid projectitem object because can display original value.

i think problem fullpath property read-only. can figure out looking @ definition in msdn - http://msdn.microsoft.com/en-us/library/vslangproj.fileproperties.fullpath.aspx - has getter defined.

to call set_value, need updating property has public setter. according properties documented on fileproperties interface, settable properties are:

• buildaction
• customtool
• customtoolnamespace
• filename
• subtype
