MFC：如何仅使用SendDlgItemMessage调整控件的大小（即没有MoveWindow） [英] MFC: How to resize a control with only SendDlgItemMessage (ie. without MoveWindow)
问题描述
是否可以在不调用MoveWindow的情况下更改Windows对象的大小（在这种情况下为
PictureBox）？
我正在写作Winamp的一个插件，我希望在其中显示一个平滑的
栏，显示不断变化的输出值。
在这个Winamp插件中，我无法使用SendMessage命令，因为它使用Winamp导致锁定。
导致锁定。我_can_使用SendDlgItemMessage。
以下代码完成工作：
MoveWindow（GetDlgItem（pitch_control_hwnd，IDC_BMP），500,400，out_val，10，FALSE ）;
不幸的是，MoveWindow在内部使用SendMessage命令，所以我
获得锁定。
我怎么能更改大小而不接受任何SendMessage调用？
注意：我知道我可以使用ProgressBar，但在WinXP中，它们是
不再流畅，但是用太大的块绘制。
欢迎任何其他想法在屏幕上显示（平滑）条形图，并且
更改尺寸也欢迎...
问候，
Theo

Is it possible to change the size of a Windows object (in this case a
PictureBox) without calling MoveWindow?
I''m writing a plugin for Winamp, in which I want to display a smooth
bar that displays a continuously changing output value.
In this Winamp plugin I cannot use the SendMessage command because it
causes lockups with Winamp. I _can_ use SendDlgItemMessage.
The following code does the job:
MoveWindow(GetDlgItem(pitch_control_hwnd, IDC_BMP), 500, 400, out_val, 10, FALSE);
Unfortunately, MoveWindow uses SendMessage commands internally, so I
get lockups.
How can I change the size without getting any SendMessage calls?
Notes: I know I can use a ProgressBar for this, but in WinXP, they are
not smooth anymore, but drawn with blocks that are too big.
Any other ideas to display a (smooth) bar on the screen with a
changing size are also welcome...
Regards,
Theo

尝试进度条控件。如果这不起作用，则覆盖WM_PAINT。
不要使用MoveWindow来获得低效的动画效果。将动画画成
窗口。
但是你会在覆盖Windows的新闻组上获得更好的帮助
SDK 。这个小组讨论了原始的C ++语言本身。

Try a Progress Bar control. If that doesn''t work, then override WM_PAINT.
Don''t use MoveWindow for a lowly animation effect. Paint the animation into
the window.
But you will get much better help on a newsgroup that covers the Windows
SDK. This group discusses the raw C++ language itself.

这是一个极端的位置，夸张，只对获得
点有用跨越。但是现在你证明了这一点已经完全没有了。
。即使是夸张也没有帮助：你把它反映回来了。
别人，这里西奥，没有理解任何东西。
也许不是夸大其词，一个有限但明确的规则：在这个
组中，是否/讨论如何使用Windows API，MFC等。
否，纯粹与Linux相关的问题/或答案/也不行。

答：因为它弄乱了人们的顺序通常阅读文字。
问：为什么这么糟糕？
A：热门帖子。
问：什么是最多的在usenet和电子邮件中烦人的事情？
That''s an extreme position, an exaggeration, useful only to get the
point across. But now you demonstrate that the point has eluded you
completely. Even the exaggeration doesn''t help: you reflect it back to
someone else, here Theo, without having understood anything.
Perhaps instead of an exaggeration, a limited but clear rule: in this
group do /not/ discuss how to use the Windows API, MFC, or the like.
No, purely Linux-related questions /or answers/ aren''t OK, either.
