使用对话框窗口上的图标C ++ Win32 API [英] Using an icon on a dialog box window C++ Win32 API

问题描述

我尝试在顶部创建一个带有图标的对话框。

I am trying to create a dialog box with an icon at the top like so.

我使用资源文件来加载图标。

I am using a resource file to load the icon like so.

IDI_ICON1          ICON           ".\\usb.ico"

我尝试使用以下代码设置窗口图标。

I have tried setting the window icon using the following code.

SendMessage(hwnd, WM_SETICON, ICON_SMALL, (LPARAM)IDI_ICON1);
SendMessage(hwnd, WM_SETICON, ICON_BIG, (LPARAM)IDI_ICON1);

hwnd是窗口。因此，我得到一个蓝色的圆形，就像Windows 7和Vista的加载图标。我几乎肯定的图标正在正确加载，当我看着任务栏，我的程序有代表我的程序的图标。如果你需要我使用的对话框窗口本身的代码，让我知道我会发布。我在Windows 7上使用mingw32 C ++编译器。感谢！

hwnd is the window. As a result, I get a blue circle that looks just like the loading icon for Windows 7 and Vista. I am almost positive the icon is being loaded correctly as when I look at the task bar, my program has that icon representing my program. If you need the code I am using for the dialog window itself, let me know I will post it. I am using mingw32 C++ compiler on Windows 7. Thanks!

推荐答案

使用LoadIcon并将图标句柄传递给WM_SETICON。 >

Use LoadIcon and pass an icon handle to WM_SETICON.

HICON hicon = LoadImageW(GetModuleHandleW(NULL), MAKEINTRESOURCEW(IDI_ICONMAIN), IMAGE_ICON, 0, 0, LR_DEFAULTCOLOR | LR_DEFAULTSIZE);
SendMessageW(hwnd, WM_SETICON, ICON_BIG, hicon);
