混合对话框和mdi项目的调试版本崩溃 [英] Crash in debug build for mixed dialog and mdi project
问题描述
亲爱的所有人，
我正在研究一个混合了对话框和MDI的项目。该项目以标签对话框项目开始。后来MDI被添加到它。单击其中一个选项卡时，将调用MDI。没有单击特定选项卡，它仍然只是一个基于对话框的项目。
该项目在发布版本中工作正常。当我进行调试构建时，当我点击初始化MDI主框架和窗口的选项卡时，我遇到了崩溃。下面给出了为MID窗口创建执行的一段代码。
崩溃消息是
MarkBullV3.exe中0x590C0983（msvcr120d.dll）的未处理异常：0xC000041D ：在用户回调期间遇到未处理的异常。
任何帮助都将非常感激。随意问你可能有的任何问题。
谢谢&此致，
Rakesh
pDocTemplate =新的CMultiDocTemplate（IDR_Test1TYPE，
RUNTIME_CLASS（CTest1Doc），
RUNTIME_CLASS（CChildFrame），//自定义MDI子框架
RUNTIME_CLASS（CTest1View））;
if（！pDocTemplate ）
返回FALSE;
AddDocTemplate（pDocTemplate）;
LOGD.LOGRP（FL，在pDocTemplate之后创造）;
pMainFrame =新的CMainFrame;
if（！pMainFrame ||！pMainFrame-> LoadFrame（IDR_MAINFRAME1））
{
LOGD.LOGRP（FL，主框架未创建）;

返回FALSE;

我发现崩溃发生在UpdateWindow上。所以我评论说，我发现崩溃仍然发生。

最后调用的函数在下面
Dear All,
I am working on a project which is a mixture of dialog and MDI. The project started as a tabbed dialog project. Later MDI was added to it. On clicking one of the tabs the MDI is invoked. Without clicking the a particular tab it remains only a dialog based project.
The project works fine in release build. When I do a debug build I get a crash when I click on the tab that initializes the MDI main frame and window. Given below is the piece of code that is executed for MID window creation.
The crash message is
Unhandled exception at 0x590C0983 (msvcr120d.dll) in MarkBullV3.exe: 0xC000041D: An unhandled exception was encountered during a user callback.
Any help would be very much appreciated. Feel free to ask any question you may have.
Thanks & Regards,
Rakesh
pDocTemplate = new CMultiDocTemplate(IDR_Test1TYPE,
RUNTIME_CLASS(CTest1Doc),
RUNTIME_CLASS(CChildFrame), //custom MDI child frame
RUNTIME_CLASS(CTest1View));
if (!pDocTemplate)
return FALSE;
AddDocTemplate(pDocTemplate);
LOGD.LOGRP(FL, "After pDocTemplate creation");
pMainFrame = new CMainFrame;
if (!pMainFrame || !pMainFrame->LoadFrame(IDR_MAINFRAME1))
{
LOGD.LOGRP(FL, "main Frame not created");
delete pMainFrame;
return FALSE;
}
m_pMainWnd = pMainFrame;
for (i = 0; i < 16; i++)
theApp.OnFileNew();
LOGD.LOGRP(FL, "Check0");
//pMainFrame->MDITile();
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
pMainFrame->ShowWindow(m_nCmdShow);
LOGD.LOGRP(FL, "Before UpdateWindow");
pMainFrame->UpdateWindow();
LOGD.LOGRP(FL, "After UpdateWindow");
totCustomPlotCount = 0;
LOGD.LOGRP(FL, "End of window creation in initinstance11");
I find the crash happens on UpdateWindow. So I commented that and I find that the crash still happens.
Given below is the stack on crash

What I have tried:

推荐答案
看来你已经找到了断言行，它告诉你发生了什么（这些消息也应该打印到Debug Output窗口）：
It seems you already found the asserting line and it tells you what has happened (the messages should have been also printed to the Debug Output window):
# ifdef _DEBUG
if (m_nMapMode == MM_NONE)
{
TRACE(traceAppMsg, 0, "Error: must call SetScrollSizes() or SetScaleToFitSize()");
TRACE(traceAppMsg, 0, "\tbefore painting scroll view.\n");
ASSERT(FALSE);////Assertion called from here
return;
}
# endif //_DEBUG
要解决此错误，请确保在创建 CScrollView <时满足要求/ code>派生视图（可能由 OnFileNew（）调用。）
这篇关于混合对话框和mdi项目的调试版本崩溃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
