richedit控件在win10下获得焦点的时候会假死10几秒？

显示全部楼层 · 2021-1-27 05:14:18

我用mfc写了一个richedit类，是从CRichEditCtrl继承来的，代码很简单，生成dll给exe调用。
测试发现：
1.在win8,win10,windows2012,windows2016上，只要第一次在richedit的框里点一下鼠标，整个窗口就会假死10多秒，没有响应,然后就正常了。
2.winxpwin7win2003win2008下怎么点击都正常。
3.把CTraceServiceControl类直接写到exe里面调用，一切正常。
监视richedit的消息，点击后，会收到MSIMEQueryPosition（行号000236），这里要卡很久，然后才是000237，应该是和输入法有关，请问谁有办法解决吗？感谢大家

卡住的时候点"暂停",然后看callstack,看卡在哪

没准只是因为少某个字体。我猜。
或者控件注册不对。

千问 · 2021-1-27 05:14:18

在64位Windows下：
64位exe和dll在目录c:\windows\system32目录下；
32位exe和dll在目录c:\windows\syswow64目录下；
所以要注意：
在win64位系统下注册32位ocx或dll需要将32位ocx或dll拷贝到c:\windows\syswow64\目录下。
且注册要用c:\windows\syswow64\regsvr32xxxxxxx.ocx或dll

引用2楼赵4老师的回复:没准只是因为少某个字体。我猜。
或者控件注册不对。直接在exe创建一个继承类，是没问题的，所以字体，控件原因可以排除

win10需要打补丁？

卸载“微软拼音输入法”就好了

千问 · 2021-1-27 05:14:18

安装其他输入法，反正不要用“微软拼音输入法”就好了
