[C#，工具栏]获取ToolBarButton的问题 [英] [C#, Toolbar] Problem with getting ToolBarButton

问题描述

你好，我今天在这里看到你一个问题，这是我很多天都无法解决的问题...
我创建了一个集成在Windows任务栏中的工具栏(例如Windows Media Player).
您可以在此处找到示例:http://goo.gl/PThTD
问题在于工具栏应该能够与另一个应用程序通信.然后我意识到我需要使用"Windows Messaging".
我找到了一个通常可以检索条形按钮(TB_GETBUTTON)的按钮.
现在我无法使用它.
我在互联网上找到了一个教程，其中提供了一个使用示例:

Hello, I am here today to see you about a problem that I can''t solve since many days...
I created a toolbar integrated into the Windows taskbar (like windows media player).
You will find an example here: http://goo.gl/PThTD
The problem is that the toolbar should be able to communicate with another application. I then realized that I needed to use the "Windows Messaging".
I found one that normally allows me to retrieve the bar buttons (TB_GETBUTTON).
Now I can not use it.
I found a tutorial on the internet, which gives an example of use:

TBBUTTON tbButton;
TBBUTTON* ipRemoteBuffer = & tbButton; // unsafe
 
for ( int i = 0 ; i < count ; i++ )
{
    User32.SendMessage(
        hToolbar,
        TB_GETBUTTON,
        ( IntPtr ) i,
        ipRemoteBuffer );
}

现在使用中，您会得到一个错误，因为编译器不再允许使用此实现...
我找不到在此函数的最后一个参数中放入什么来检索按钮.

Now in use, you get an error because the compiler no longer allows the use of this implementation ...
I can not find what to put in the last parameter of this function to retrieve the button.

User32.SendMessage (
         toolbar,
         TB_GETBUTTON,
         IndexButton
         (IntPtr) variable);

我的按钮位于工具栏中的"ToolBarButton"中，然后键入"ToolBar".
如果您有任何想法或建议或其他任何东西，我会很感兴趣.
预先谢谢你

推荐答案

最后一个参数应该是指向TBBUTTON结构的指针. 您发送的消息将通过该结构检索工具栏按钮的详细信息.
例如

The last parameter should be a pointer to a TBBUTTON structure.
And the message you send retrieves the toolbar button''s details through that structure.
Eg

TBBUTTON tbBtn = new TBBUTTON();
SendMessage(hToolbar, TB_GETBUTTON, i,
  tbBtn);

TBBUTTON结构包含一些信息，例如它的状态/样式等.
请检查msdn，以获取有关结构&的更多详细信息.用法.

您对该函数的互操作定义为

The TBBUTTON structure holds some info like it''s state/style etc.
Check the msdn for more details on the structure & usage.

Your interop definition for the function would be

[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern int SendMessage(IntPtr hWnd, int msg, int wParam, out TBBUTTON tbBtn);

(您还必须定义TBBUTTON结构)

(you''ll have to define the TBBUTTON structure as well)

好，谢谢.我会尝试您的解决方案.
但是我还有另一个问题.类型"TBBUTTON"和"ToolBarButton"之间有什么区别?

Ok, thanks you. I''ll try with your solution.
But i have an other question. What is the diference between the types ''TBBUTTON'' and ''ToolBarButton'' ?
