Declare integer SearchTreeForFile In IMAGEHLP.DLL String lpRootPath , String lpInputName, String lpOutputName

sPathBuffer = Space(512)

SearchTreeForFile("C:\", "prova.txt", sPathBuffer )

If i execute the code the sPathBuffer contains a empty value and not a path where the file is find.
If i use this function in VB it's correct!

Why this ?

Thank
