问题描述

我正在开发一个 C++ Api 项目.

我将使用 dialogboxparam 创建一个对话框...

我已完成创建和设置文本框、标签和按钮...它的工作正常...

现在我想在对话框顶部添加一张图片...

我确实在 WM_INITDIALOG 中使用了此代码:

i did use this code in WM_INITDIALOG:

HBITMAP hImage= (HBITMAP)LoadImage(NULL,L"C:\WINDOWS\system32\BMA-Images\login-header",IMAGE_BITMAP,LR_DEFAULTSIZE ,LR_DEFAULTSIZE ,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
            SendMessage(_hwnd,STM_SETIMAGE,IMAGE_BITMAP,(LPARAM)hImage);

但它没有工作......任何人都可以帮助解决这个问题...提前致谢索努

But it didnt work... Can anyone help to resolve this... Thanks in advance Sonu

推荐答案

最简单的方法是覆盖窗口的 WM_PAINT 并在该点(在 BeginPaint 和 EndPaint 之间)调用绘制位图

The easiest way is to override the WM_PAINT for the window and paint the bitmap at that point (between the BeginPaint and EndPaint) calls

这里有一个基于 MFC 的示例:

There is an MFC based example here:
