推荐答案

MSDN [ ^ ]说:
默认情况下，主机的大小和位置是从注册表中与其他应用程序设置一起加载的."
这意味着EnableLoadWindowPlacement(TRUE);是冗余的，因为它是默认选项.

它还说:
"[加载]在CWinAppEx :: LoadState期间发生."
这意味着您需要调用LoadState.因为没有提及ReloadWindowPlacement，所以暗示它们不兼容.


如果您随后阅读了 ReloadWindowPlacement [
您正在使用2种单独的方法进行保存和加载，这些方法似乎以单独的注册表位置/键或格式保存/加载数据.

选择1.

MSDN[^] says:
"By default, the size and location of the main frame is loaded from the registry together with other application settings."
This means that EnableLoadWindowPlacement(TRUE); is redundant as it is the default option.

It also says:
"[The load] occurs during CWinAppEx::LoadState."
The means you need to call LoadState. Because there is no mention of ReloadWindowPlacement it is implied that they are incompatible.


If you then read the page for ReloadWindowPlacement[^] it says:
"Use the function CWinAppEx::StoreWindowPlacement to write the size and location of a window to the registry."

You are using 2 separate methods to save and load, which seem to save/load the data in separate registry locations/keys or formats.

Pick 1.
