CMFCShellListCtrl 和 CMFCShellTreeCtrl 关联的问题

Question

今天学着Visual C++ 2008 Feature Pack的Explorer例子，做了一个窗口切分的Explorer，结果在关联CMFCShellListCtrl 和 CMFCShellTreeCtrl的时候老是报错。恳请大家分析分析看看如何解决。我试过模态对话框的情况下可以很容易进行关联CMFCShellListCtrl 和 CMFCShellTreeCtrl，没有任何问题。

以下是代码

Answer 1

((CMainFrame*) AfxGetMainWnd ())->GetFolders ().SetRelatedList (&m_ShellListCtrl);

这句会造成断言错误，debug后显示是afxshelltreectrl.cpp第73行

void CMFCShellTreeCtrl::SetRelatedList(CMFCShellListCtrl* pShellList)
{
ASSERT_VALID(this); 这个地方断言错误。

m_hwndRelatedList = (pShellList == NULL) ? NULL : pShellList->GetSafeHwnd();
if (pShellList != NULL)
{
pShellList->m_hwndRelatedTree = GetSafeHwnd();
}
}

Answer 2

错误信息是什么？

还有，你用的是哪个版本的ＶＳ？

Please mark this reply as answer if it helps you! Thanks for your cooperation! Good Luck to you.

Answer 3

谢谢，问题已经搞定了。

问题出在MDI方式下各个View之间进行数据交换、互访方式上。通过DOC来互访就没有问题了。
