启用 WS_EX_COMPOSITED 标志并添加列表视图控件后，未绘制列表视图的框架.仅当ListView类型设置为报告时，才会发生这种情况.

After enabling the WS_EX_COMPOSITED flag and added a listview control the frames of listview is not drawn. This only happens if ListView type is set to report.

将Listview类型更改为Report以外的其他类型，并绘制框架

Changing Listview type to other than Report and frames are drawn

删除 WS_EX_COMPOSITED 标志可解决此问题，但闪烁现象又回来了

Removing WS_EX_COMPOSITED flag fixes the issue but the flickering comes back

推荐答案

在对话框扩展样式"中使用 WS_EX_COMPOSITED 解决了问题.

Issue is fixed by using WS_EX_COMPOSITED in the Dialog box Extended styles.

解决问题的方法是在Listview上使用 SetParent ，并将其作为父级而不是子对话框附加到主窗口.现在，它可以正确显示其框架.

Fixes for the edit of my question is by using SetParent on the Listview and attach it to the main window as it's parent instead of the sub dialog. Now it shows its frame correctly.

所以我认为这个有问题

另一个对话框上的列表视图->使用 CreateDialogParam 将其附加到主对话框(在选项卡控件上方). WS_EX_COMPOSITED 在标签控件上设置

Listview on another dialog -> attach it to the main dialog(Over tab control) using CreateDialogParam. WS_EX_COMPOSITED set on tab control

结果: 有XP绘图问题.非常呆滞.报表类型中列表视图的隐藏框架.如问题编辑所示.

Result: has XP drawing issues. Very sluggish. Hidden frames of listview in report type. as seen in question edit.

新方法 另一个对话框上的Listview->使用 CreateDialogParam 将其附加到主对话框(在选项卡控件上方). WS_EX_COMPOSITED 也在选项卡控件和主对话框中设置.调用 SetParent ，将列表视图与父对话框关联为父对话框.

New method Listview on another dialog -> attach it to the main dialog(Over tab control) using CreateDialogParam. WS_EX_COMPOSITED set on tab control and main dialog as well. Call SetParent associate the listview with Main dialog as it's parent.

结果: 非常平滑的绘图. XP也没有问题.即使禁用桌面合成，也没有任何闪烁.并将 WM_ERASEBKGND 保留为主对话框的默认设置，并且不进行自定义 WM_PRINT 处理.但是只需要在子对话框DialogProc上禁用 WM_ERASEBKGND 以将return设置为1.

Result: Very smooth drawing. XP has no issues either. No flickering at all even when disabling desktop composition. And leave WM_ERASEBKGND as default for main dialog and no custom WM_PRINT handling. But WM_ERASEBKGND disabling is only needed on the sub dialog DialogProc to set return to 1.
