如何显式设置任务栏图标? [英] How to explicitly set taskbar icon?

问题描述

在 Visual Studio 中，我生成了一个普通的旧 Win32 应用程序，并剥离了所有资源和生成的代码，以便我的应用程序包含以下内容:

In Visual Studio I generated a plain old Win32 application and stripped all the resources and generated code so that my application consists of this:

#include "stdafx.h"
#include "IcoTest.h"

int APIENTRY _tWinMain(HINSTANCE hInstance,
                 HINSTANCE hPrevInstance,
                 LPTSTR    lpCmdLine,
                 int       nCmdShow)
{
    ::MessageBox( NULL, L"Testing", L"Test", MB_OK );
}

当我运行应用程序时，我看到的是:

When I run the application, this is what I see:

所以问题是我可以更改任务栏中的默认应用程序图标吗?如果是这样，需要添加什么代码来实现?

So the question is can I change that default application icon in the taskbar? If so, what code needs to be added to do it?

这就是我所做的，这种工作是有效的，但并不理想.新图标显示正常，但 Vista 中的任务栏预览窗口不起作用，系统菜单也不起作用，所以我暂时不理会它.

Here's what I did, and this kind of works but it isn't ideal. The new icon shows up alright, but the taskbar preview window in Vista doesn't work and the system menu doesn't work so I'm just going to leave it alone for now.

HWND CreateDummyWindow(HINSTANCE hInstance, int iconId, LPCTSTR taskbarTitle)
{
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style          = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc    = DefWindowProc;
wcex.cbClsExtra     = 0;
wcex.cbWndExtra     = 0;
wcex.hInstance      = hInstance;
wcex.hIcon          = LoadIcon(hInstance, MAKEINTRESOURCE(iconId));
wcex.hCursor        = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground  = 0;
wcex.lpszMenuName   = 0;
wcex.lpszClassName  = taskbarTitle,
wcex.hIconSm        = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(iconId));
ATOM atom = RegisterClassEx(&wcex);
HWND wnd = ::CreateWindow( 
    wcex.lpszClassName, taskbarTitle, WS_ICONIC | WS_DISABLED,
  -1000, -1000, 1, 1, NULL, NULL, hInstance, NULL);
return wnd;
}

int APIENTRY _tWinMain(HINSTANCE hInstance,
                 HINSTANCE hPrevInstance,
                 LPTSTR    lpCmdLine,
                 int       nCmdShow)
{
    HWND wnd = CreateDummyWindow(hInstance, IDI_ICON1, _T("Test") );
    ::MessageBox( wnd, _T("Testing"), _T("Test"), MB_OK );
    ::DestroyWindow( wnd );
}

推荐答案

任务栏上显示的图标取自窗口本身.如果唯一的窗口是标准的 Windows MesssageBox，那么您将获得某种操作系统默认值.你必须创建你自己的窗口并给它一个图标，然后 Windows 会使用它.

The icon shown on the task bar is taken from the window itself. If the only window is the standard Windows MesssageBox, then you'll get some sort of OS default. You have to create your own window and give it an icon, then Windows will use that.
