1. 获取Debug或Release所在的路径
CString GetModuleDir()
{
 HMODULE module = GetModuleHandle(0);
 char pFileName[MAX_PATH];
 GetModuleFileName(module, pFileName, MAX_PATH);
 
 CString csFullPath(pFileName);
 int nPos = csFullPath.ReverseFind( _T('\\') );
 if( nPos < 0 )
  return CString("");
 else
  return csFullPath.Left( nPos );
}

2. 获取当前工作路径（dsp所在路径）

//获取工作路径
CString GetWorkDir()
{ 
 char pFileName[MAX_PATH];
 int nPos = GetCurrentDirectory( MAX_PATH, pFileName);
 
 CString csFullPath(pFileName);  
 if( nPos < 0 )
  return CString("");
 else
  return csFullPath;
}
