Hi

I have a virtual function setStartupDirectory()

virtual bool setStartupDirectory(const SysString &sStartupDirectory) = 0;

When I am calling this function
setStartupDirectory((const SysString &)m_pApplicationFolderNarrow);
I am getting this error
Error 2 error C2664: 'setStartupDirectory' : cannot convert parameter 1 from 'const SysString' to 'const SysString &'

Am I missing something

Here..
c++ Syntax (Toggle Plain Text) 
  1. virtual void CSample1::Sample(SysString str)
  2. (
  3.    if(str.empty())
  4.       return;
  5.    //...
  6. )
  7. virtual void CSample2::Sample(SysString &str)
  8. {
  9.    str="what's up";
  10. }
  11. int main()
  12. {
  13.    SysString str1="check";
  14.    SysString str2;
  15.    CSample1 s1;
  16.    CSample2 s2;
  17.    s1.Sample(str1);
  18.    s2.Sample(str2);
  19.    return 0; 
  20. }

You can directly make the call to the function as follows

setStartupDirectory(m_pApplicationFolderNarrow);
