大神們，先看正常顯示界面
然后是點擊最大化后，就變成這樣了。（在win7上正常，在win10上會出現這個問題）
最后貼上引起這個原因的代碼，但是這段代碼不能去掉，我要用，這段代碼可以解決頁面切換時的閃爍問題。
如果去掉這段代碼，確實可以完整顯示視窗，但是閃爍太嚴重了。
大神們有什么解決辦法嗎？感謝感謝

WM_NCCALCSIZE重繪一下。uj5u.com熱心網友回復：
首先感謝大神，然后我自己去搜了一圈，好像沒找到啥實用的東西。大神能再幫忙指導一下怎么重繪嗎？或者有什么文章鏈接，分享一下，感謝感謝uj5u.com熱心網友回復：

大神你看看3樓的代碼，我的主視窗，就繼承的這個FormBaseuj5u.com熱心網友回復：
WndProc加一個判斷試試：
case WM_NCCALCSIZE: {//0x83
Refresh();
}
break;
