一次显示CAxDialogImpl和CWindowImpl. [英] Display a CAxDialogImpl and a CWindowImpl at once.
问题描述
亲爱的ATL员工，
我有一个可能是新手的问题，对此深表歉意.我有一个
CAtlExeModuleT(请参见下面的代码)，并且想要调整一个我得到的样本.首先，在CAtlExeModuleT的PreMessageLoop中创建模式CAxDialogImpl对象.我想做的是使对话框无模式，以便我可以另外显示CWindowImpl
(可以选择稍后使其全屏显示jpeg).
因此可以创建一个CAxDialogImpl和CWindowImpl哪个都以桌面为父级(在Create调用中将NULL作为第一个参数)?还是它们必须彼此关联(形成一个父子链)?当我执行下面的代码时，程序
运行一会儿，然后结束而不显示任何内容.在创建窗口之后添加了
Sleep(5000)，并且该窗口可见.
所以这似乎是范围的问题.但是对话框不可见.
如何正确创建窗口和无模式对话框并且不会超出范围，以便事件
处理正常?我是否必须将它们放入PreMessageLoop
(我尝试过，但是效果是相同的；我是否需要
PreMessageLoop)? -我希望使用_tWinMain解决方案仅在可能的情况下摆脱PreMessageLoop.
请帮助，对于那些对ATL有一定经验的人来说，这不是一个难题.您确实会极大地帮助我，因为尽管有两本关于ATL和Web的书，我还是被完全卡住了(我只发现在他们的考试中，他们使用较旧的CCom东西，并在
_tWinMain和
而不是如何在CAtlExeModuleT的上下文中使用ATL窗口，就像在这种情况下我需要的那样(ATL 8.0，Visual Studio 2005).
希望能给我带来帮助
最诚挚的问候，
Peter.

Dear ATL people,
I have a maybe-newbie question, so sorry for that. I have a
CAtlExeModuleT (see code below) and want to adjust a sample that I
got. It started by creating a modal CAxDialogImpl object in the
PreMessageLoop of the CAtlExeModuleT. What I wanted to do is to make
the dialog modeless so that I can display additionally a CWindowImpl
(with the option to make it fullsceen later, to display jpegs).
So is it possible to create a CAxDialogImpl and a CWindowImpl which
both have the desktop as parent (giving NULL as first parameter in
the Create call)? Or do they have to be related to each other (forming
a chain of parent-child)? When I execute the code below the program
runs for short and then ends without displaying anything. I added
a Sleep(5000) after the window creation and the window was visible.
So it seems to be a matter of scope. But the dialog wasn't visible.
How could I get it work that the window AND the modeless dialog are
created correctly and do not go out of scope so that the event
handling works properly? Do I have to put them in PreMessageLoop
(I tried this, but the effect was the same; do I need
PreMessageLoop)? - I would prefer a solution with _tWinMain only to
get rid of the PreMessageLoop if possible.
Please help, I think it's not a hard problem for someone who has some
experience with the ATL. You would really help me greatly because I am
totally stuck despite two books on ATL and the web (I only found exam-
ples where they use the older CCom stuff with a main message loop in
_tWinMain and TranslateMessage(&msg) and DispatchMessage(&ms) into it)
but not how to use ATL windows in context of the CAtlExeModuleT like
I need in this case (ATL 8.0, Visual Studio 2005).
So with the hope on help I send you
Best regards,
Peter.
Here comes the code:
推荐答案
在//Sleep之后放入消息循环(5000)条评论
味精味精；
Put a message loop in after the //Sleep(5000) comment
MSG msg;
//主消息循环:
同时 (GetMessage(& msg，NULL，0，0))
{ while (GetMessage(&msg, NULL, 0, 0))
{ TranslateMessage(& msg); TranslateMessage(&msg); DispatchMessage(& msg); DispatchMessage(&msg); } 这篇关于一次显示CAxDialogImpl和CWindowImpl.的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
