Question

我正在开发一个对话框和MDI混合的项目。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运行良好。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窗口创建执行的代码段。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。

非常感谢任何帮助。随意提出您可能遇到的任何问题。

谢谢＆amp;问候，勒凯什

你可以很容易地看到你在函数CScrollView::OnPrepareDC的第387行得到了一个ASSERT。位于C：\ Program Files（x86）\ Microsoft Visual Studio 12.0 \ VC \ atlmfc \ src \ mfc \ viewscrl.cpp

正如您可以在调试输出和源代码中读到的原因是：

错误：在绘制滚动视图之前必须调用SetScrollSizes（）或SetScaleToFitSize（）。
