MFC分割窗口出现assertion failed， winsplit.cpp Line:367

guzi19801130 2017-08-04 03:17:02

在VS2010的C++环境中的MFC中，创建分割窗口：
1、在MainFrm.h文件中的CMainFrame 类中加入：
protected: // control bar embedded members
CSplitterWnd m_Sp1; //分割成两个窗口
virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext);
2、在类视图中创建新类：
class CControlForm : public CFormView
3、再MainFrm.cpp文件中重写OnCreateClient 函数，并加入头文件#include "ControlForm.h"：
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{

int cx = GetSystemMetrics(SM_CXSCREEN);
int cy = GetSystemMetrics(SM_CYSCREEN);
float m_bKuanPin=float(cy)/float(cx);

//将主窗口分为一行两列
if(m_Sp1.CreateStatic(this,1,2)==NULL)
return FALSE;
}

为什么编译能成功，当运行EXE文件时，报断言错误：assertion failed， winsplit.cpp Line:367。
还请老师指教！！！

CWnd* CSplitterWnd::GetPane(int row, int col) const { ASSERT_VALID(this); CWnd* pView = GetDlgItem(IdFromRowCol(row, col)); ASSERT(pView != NULL); // panes can be a CWnd, but are usually CViews return pView; } 就是没有创建 view

好的好的非常感谢啊老师！！！

第367行，指向的是： ************** return pView; } BOOL CSplitterWnd::IsChildPane(CWnd* pWnd, int* pRow, int* pCol) { ********************* 中间的空行

断言错误可以在Dug的堆栈能够看到有用信息

	m_wndSplitter.CreateView(1, 2, RUNTIME_CLASS(CYaChangeSplitView), size, pContext);

非常感谢不过还是EXE断言错误：assertion failed winsplit.cpp Line:367 是不是项目配置哪里出了毛病

打开 winsplit.cpp 看看 Line:367 cx*3/5 改 cx/5*3 或者（cx*3）/5 ；因为 3/5 可能为0 ！

不是的，在BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { if(m_Sp1.CreateStatic(this,1,2)==NULL) return FALSE; } 函数中，只有一个创建m_Sp1.CreateStatic命令，EXE也会assertion failed winsplit.cpp Line:367
