如何在 c++ win32 API 的对话框中设置图像?
我正在开发一个 C++ Api 项目.
i have developing a C++ Api project.
我将使用 dialogboxparam 创建一个对话框...
i will use dialogboxparam to create a dialogbox...
我已完成创建和设置文本框、标签和按钮...它的工作正常...
i done to create and set the textbox,labels and buttons... its work fine...
现在我想在对话框顶部添加一张图片...
now i want to add a image in the top of the dialogbox...
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:
