CFrameWnd::OnCreate(lpCreateStruct)出错是怎么回事啊???

linao 2005-09-12 05:52:39
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)//这里出的错
return -1;


错误现象是:Unhandled exception in mytext.exe:0xC0000005 access violation

各位,这是回是什么情况造成的? 该怎么办啊???

前面没有代码...init中的代码我也注释了,但还是要报错

wincore.cpp中的错误到了这里

CATCH_ALL(e)
{
lResult = AfxGetThread()->ProcessWndProcException(e, &pThreadState->m_lastSentMsg);
TRACE1("Warning: Uncaught exception in WindowProc (returning %ld).\n",
lResult);
DELETE_EXCEPTION(e);
}

不好意思，我 对MFC的流程不太清楚，这是init和create的代码，感觉没什么特别的，麻烦看一下。感谢感谢！！！

BOOL MytextApp::InitInstance()
{
AfxEnableControlContainer();
#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif

SetRegistryKey(_T("Local AppWizard-Generated Applications"));

LoadStdProfileSettings(); // Load standard INI file options (including MRU)

CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CMytextDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
NULL);
AddDocTemplate(pDocTemplate);

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
return FALSE;

// The one and only window has been initialized, so show and update it.
m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);
m_pMainWnd->UpdateWindow();

return TRUE;
}

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)//这里出的错误
return -1;

if (CFrameWnd::OnCreate(lpCreateStruct) == -1)这一句的前面还有什么代码吗？
感觉不是这里的错误，而是其它的地方内存操作有误
关于c的代码
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || !m_wndToolBar.LoadToolBar(IDR_MAINFRAME)) { TRACE0("未能创建工具栏\n"); return -1; // 未能创建 } if (!m_wndStatusBar.Create(this) || !m_wndStatusBar.SetIndicators(indicators, sizeof(indicators)/sizeof(UINT))) { TRACE0("未能创建状态栏\n");

        VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
        向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
