Hi,

I don't know why the function ExtractFilePath doesn't work on me when I ugraded my project from BCB6. The code is here:

  AnsiString FName = Application->ExeName;
  AnsiString path = ExtractFilePath(FName);

path is Null. It is strange. I did test on a brand new project made under C++ Builder 2007, the function works. I don't know why. Has any one had that problem before? Any clue of what is going on? 

Thanks.

Gene.

That seemed silly. I turned off "Old-style class parameter argument", then the extractfilepath worked.

The only way that can happen is if FName was empty string to begin with. 
That woul suggest the Win32 API GetModuleFileName() function failed inside 
of Application->ExeName somehow.

We have something strange with ExtractFilePath(Application->ExeName) but if 
I remember correctly the Application.Exe name has some ../ in it to go up a 
level and then down to a directory.

We used to just get the absolute path I think.

The Application->ExeName property cannot return such a value.

The Application->ExeName property getter calls ParamStr(0), which calls 
GetModuleFileName(), which always returns an absolute path to the file that 
the calling process was spawned from.
