如何避免在mfc中默认生成windows API的热键？ [英] How to avoid default hot key generation of windows API in mfc?

问题描述

在我的VC ++项目中，我遇到了这样的问题。即，有一个编辑框，它接受来自用户的字符串输入。按下另一个按钮时，此字符串将设置在按钮上。使用

In my VC++ project i got an issue like this. ie, there is an edit box which accepts string input from user. while pressing another button, this string will be set on a Button. to set this text on this button iam using

SetWindowText()

API在此按钮上设置此文本。但问题是用户输入这样的输入

& abcd然后&不会在按钮上设置。它将a作为热键。即，

现在文本将显示在按钮上，如 a bcd。如何避免Windows API的默认热键转换？这可能吗？如果是，请给我回复。

API. But the issue was when user enter the input like this
"&abcd" then "&" will not be set on button. It will make "a" as hot key. ie,
now the text will be displayed on button like this "abcd". How can i avoid default hot key conversion of windows API? Is this possible? If yes give me a reply.

推荐答案

您有两个选项可以避免使用&符号生成热键：

1.全部删除字符串中的&符号：& button - >按钮

2.确保字符串中的单个&符实例加倍：& button - > && button

   第一个&符号逃脱第二个&符号，只显示一个&符号。

You have two options to avoid having the ampersand generate a hot key:
1. Remove all ampersands from the string: &button -> button
2. Make sure that single ampersand instances inside the string are doubled: &button -> &&button
   The first ampersand escapes the second one and only one ampersand is displayed.

除了Manfred在解决方案1中提到的选项外，还有一个第三个：

使用所有者绘制按钮时（请参阅 CButton :: DrawItem（） [ ^ ]）， DrawText（）格式标志 DT_NOPREFIX 将禁用前缀字符的处理并按原样显示文本。

Besides the options mentioned by Manfred in solution 1, there is a third one:
When using owner draw buttons (see the MSDN example at CButton::DrawItem()[^]), the DrawText() format flag DT_NOPREFIX will disable processing of prefix characters and show the text as it is.
