Project Events - project path

[kevininstructor]

I have a solution under VS2005 were there are two projects.
One project is physically located under the Solution folder.
One project is physically not located under the Solution folder.

In the BuildEvents.OnBuildProjConfigBegin event the first parameter is Project which is a string with the realative path and project file name.

I am in search of how to get the absolute path and project file name.

So I get this from the project param
../../Jenkins/PDF_Extraction/bin/Debug/PDF_Extraction.exe

I want
../../Jenkins/PDF_Extraction/PDF_Extraction.vbproj
or the absolute path as shown below
C:/DotNetLand/Jenkins/PDF_Extraction/PDF_Extraction.vbproj

Any help would be great, thanks in advance
