{ Question: Could anyone point me to any function that can receive an HTML style relative path as its input and return a full path as its output based on the exe's current location, e.g Input: '.... est2.dat' Output: C:folder1 est2.dat (assuming that the executable is running from C:folder1folder2folder3Project1.exe) } { Answer: PathCombine() Concatenates two strings that represent properly formed paths into one path, as well as any relative path pieces. } functionPathCombine(lpszDest: PChar; const
lpszDir, lpszFile: PChar): PChar; stdcall
; external
'shlwapi.dll' name 'PathCombineA'; function
PathCombineA(lpszDest: PAnsiChar; const
lpszDir, lpszFile: PAnsiChar): PAnsiChar; stdcall
; external
'shlwapi.dll'; function
PathCombineW(lpszDest: PWideChar; const
lpszDir, lpszFile: PWideChar): PWideChar; stdcall
; external
'shlwapi.dll'; { Requires Windows 2000 (or Windows NT 4.0 with Internet Explorer 4.0 or later); Requires Windows 98 (or Windows 95 with Internet Explorer 4.0 or later) } procedure
TForm1.FormCreate(Sender: TObject); var
dest: string
; BaseFile, RelativePath: String
; begin
BaseFile := 'C:folder1folder2folder3'; RelativePath := '.... est2.dat'; SetLength(dest, MAX_PATH); PathCombine(@dest[1], PChar(ExtractFilePath(BaseFile)), PChar(RelativePath)); SetLength(dest, StrLen(@Dest[1])); ShowMessage(dest); end
; { The ExtractRelativePath function takes a base directory but the ExpandFilename function does the expansion based on the current directory not a given base path. } RelativePath := ExtractRelativePath(ExtractFilePath(BaseFile), TargetFile);
