建立空文档失败解决办法

建立空文档失败
建立的MFC工程,在编译时出现 "建立空文档失败 "的错误,应该如何解决,报错地方的代码如下:


BOOL   CExchApp::InitInstance()
{
HWND   A=FindWindow(NULL, "for   Exch ");
if(A!=NULL)
{
SetForegroundWindow(A);
CloseHandle(A);
return   false;
}
AfxEnableControlContainer();
#ifdef   _AFXDLL
Enable3dControls(); //   Call   this   when   using   MFC   in   a   shared   DLL
#else
Enable3dControlsStatic(); //   Call   this   when   linking   to   MFC   statically
#endif
//   Change   the   registry   key   under   which   our   settings   are   stored.
//   TODO:   You   should   modify   this   string   to   be   something   appropriate
//   such   as   the   name   of   your   company   or   organization.
SetRegistryKey(_T( "Local   AppWizard-Generated   Applications "));
LoadStdProfileSettings();     //   Load   standard   INI   file   options   (including   MRU)
//   Register   the   application 's   document   templates.     Document   templates
//     serve   as   the   connection   between   documents,   frame   windows   and   views.
CSingleDocTemplate*   pDocTemplate;
pDocTemplate   =   new   CSingleDocTemplate(IDR_MAINFRAME,RUNTIME_CLASS(CExchDoc),RUNTIME_CLASS(CMainFrame),RUNTIME_CLASS(CExchView));
AddDocTemplate(pDocTemplate);
CCommandLineInfo   cmdInfo; //   Parse   command   line   for   standard   shell   commands,   DDE,   file   open
ParseCommandLine(cmdInfo);
if   (!ProcessShellCommand(cmdInfo)) //   在这报错
return   FALSE;
m_pMainWnd-> ShowWindow(SW_SHOW);
m_pMainWnd-> UpdateWindow();
m_pMainWnd-> SetWindowText( "for   Exch ");
m_pMainWnd-> CenterWindow();
return   TRUE;
}

你是不是用了 richedit控件？
用了的话一般要在InitInstance()
里用AfxInitRich初始化：
