上下文帮助处理问题 [英] Context Help handling problem

问题描述

我试图在对话框上使用上下文帮助来显示我的应用程序关于Box".

我发现处理帮助"按钮按下的唯一方法是捕获WM_NCLBUTTONDOWN消息.我遇到的问题是，一旦我得到ABout框，就按下按钮，而第二次按下时，鼠标光标上会出现一个帮助图标.然后，如果我再次按下该按钮，则会出现关于"框.

首先，我是否使用了正确的消息处理程序(我怀疑没有)，其次，如果我使用了正确的处理程序，如何避免需要两次按下按钮才能获得单片印刷机的正确功能，即关于".每次按下按钮都会出现一个框?

TIA

Hi,

I''m trying to use the Context Help on my dialog to display my application About Box.

The only way I have found to handle the press of the Help button is to catch the WM_NCLBUTTONDOWN message. The problem that I am seeing with this if I press the button once I get my ABout box, when I press it the second time I get a little help icon appear on my mouse cursor. Then if I press the button again my About box appears.

Firstly, am I using the correct message handler (and I suspect not), and secondly, if I am using the correct handler, how can I prevent needing to press the button twice to get the correct functionality of a singel press, i.e. the About box appears every time that I press the button?

TIA

Tony

推荐答案

问题已解决，

我已经在函数的底部保留了默认的CDialog :: OnNcLButtonDown()处理函数，这需要进一步的处理.
删除该调用，该功能就像螺母一样工作.

Problem solved,

I had left the default CDialog::OnNcLButtonDown() handler at teh bottom of the function, and it was requiring further handling.
Remove the call and the function works sweet as as nut.
