如何使用SendMessage/PostMessage函数？
我想将这些消息发送到应用程序：
<00010> 00830BB8 S WM_GETDLGCODE
<00011> 00830BB8 R WM_GETDLGCODE fuDlgCode:DLGC_WANTARROWS
<00012> 00830BB8 P WM_PAINT hdc:00000000
<00013> 00830BB8 S WM_ERASEBKGND hdc:DD012964
<00014> 00830BB8 R WM_ERASEBKGND fErased:True
<00015> 00830BB8 P WM_TIMER wTimerID:1 tmprc:00000000
<00016> 00830BB8 S WM_GETDLGCODE
<00017> 00830BB8 R WM_GETDLGCODE fuDlgCode:DLGC_WANTARROWS
<00018> 00830BB8 S WM_GETDLGCODE
<00019> 00830BB8 R WM_GETDLGCODE fuDlgCode:DLGC_WANTARROWS
<00020> 00830BB8 P WM_PAINT hdc:00000000
<00021> 00830BB8 S WM_ERASEBKGND hdc:7601294E
<00022> 00830BB8 R WM_ERASEBKGND fErased:True
这些消息来自 Spy++。 如何使用 C# 使用 SendMessage/PostMessage 函数发送？
编辑.. 谢谢你们的回复！ 我解决了我的问题，再次感谢！

<00022> 00830BB8 R WM_ERASEBKGND fErased:True
These are from Spy++.

我尝试将密钥发送到应用程序，并使用 Spy++ 查看消息。
具体来说，我想将箭头键发送到应用程序。从 Spy++ 中，我看到发送了上述消息。在我尝试了一切之后，我在应用程序中发送了以下消息：
现在可以正常工作了！谢谢你们！
I tried to send keys to an application, and I used the Spy++ to see the messages goes to this.
Specifically I wanted to send arrow keys to the application. From the Spy++, I saw that sent the above messages. After I had tried everything, I sent in the application, the below messages:
Now works properly! Thanks guys!
您无法发送与绘制窗口相关的消息。只有系统可以发送它们。如果您需要强制重新绘制，那么您只需调用 InvalidateRect 即可。
您可能可以成功发布计时器消息。
您可能不需要发送 WM_GETDLGCODE 消息，因为它们没有副作用。
You cannot send the messages related to painting the window. Only the system can send them. If you need to force a re-paint then you simply call InvalidateRect.
Timer messages you could probably post successfully.
The WM_GETDLGCODE messages you probably don't need to send since they don't have side effects.
