求大神指點菜鳥吧uj5u.com熱心網友回復：
你使用的API版本和作為引數代入的字串型別不匹配。把
TextOut(hDC,begin.x,begin.y,outInfo,1);
改成
TextOutW(hDC,begin.x,begin.y,outInfo,1);
即可，注意細微差別。
uj5u.com熱心網友回復：
另外，我得補充一下，你這個代碼有太多太多的改進空間了。在成功編譯之前，你需要改掉兩處TextOut為TextOutW，注意是兩處！！！然后還需要把函式CreateMyFont的定義部分的函式名拼寫對(定義的地方少寫了一個e字，注意是定義的部分，不是宣告的部分)uj5u.com熱心網友回復：
我明白了，謝謝你了，以后會注意！轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/103023.html
