如何在C ++ Win32 API的对话框中设置图像? [英] how to set image in dialogbox in c++ win32 API?

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，标签和按钮的操作...工作正常...

现在我想在对话框顶部添加图像...

我确实在WM_INITDIALOG中使用了以下代码:

  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); 

但是没用...任何人都可以帮助解决此问题...提前致谢声纳

解决方案

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

这里有一个基于MFC的示例:

i have developing a C++ Api project.

i will use dialogboxparam to create a dialogbox...

i done to create and set the textbox,labels and buttons... its work fine...

now i want to add a image in the top of the dialogbox...

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);

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

解决方案

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

There is an MFC based example here:
