HwndHost-诸如WndProc，TabIntoCore等重写的函数不会被调用 [英] HwndHost - overritten functions like WndProc, TabIntoCore etc. get no invoke

问题描述

我们尝试将Delphi窗口托管到Wpf应用程序中，但存在一些小问题.

We try to host a Delphi Window into a Wpf-Application, there are some small problems.

我们无法将焦点设置到包含win32-Application的选项卡上.

We are not able to set the focus to the tab which contains the win32-Application. 

我们尝试覆盖WndProc和其他一些函数，但是它们没有得到调用.

We tried to override the WndProc and some other functions, but they do not get the call.

我们为什么没有得到这些函数的调用?

Are there any reasons why we do not get the call of these functions?

Hi noibi,

>>我们无法将焦点设置到包含Win32应用程序的标签上.

据我所知，该程序属于另一个程序域.因此，您不能将焦点设置到包含win32应用程序的选项卡.

As far as I know, The program belongs to a different program domain. So, you can not able to set the focus to the tab which contains the win32 Application.
