想让应用内部多一个内置的文本编辑器,直接给它理解成多窗口吧.
但是主窗口(如下图)已近存在了,就是已经把窗口给注册了,那如何再多加一个内置窗口呢?

这是按钮"编辑器"的命令处理

case WM_COMMAND:

        {

            int wmId = LOWORD(wParam);

            // 分析菜单选择:

            switch (wmId)

            {

            case IDM_EXIT:

                DestroyWindow(hWnd);

                break;

            case IDC_BUTTON:

                MessageBox(NULL, NULL, NULL, NULL);

                //打开文本编辑器

            default:

                return DefWindowProc(hWnd, message, wParam, lParam);

            }

        }

        break;

目标:点击"编辑器",运行以下代码
下面是文本编辑器的代码(WINAPI)

LRESULT CALLBACK EditProc(HWND, UINT, WPARAM, LPARAM);

#define BUFFER(x,y) *(pBuffer + y * cxBuffer + x)

一个 exe 只要一个消息循环

辛苦你了,但不是这一个意思因为我把这个窗口单独放在一个头文件里面,意思就是点击"编辑器"按钮的时候,从这个头文件的TextEdit函数显示窗口不一定要消息循环从头说起,这是之前一个类似于当前工程的代码辛苦一下,看一下这个代码吧

        MAKEINTRESOURCE(IDD_TIPBOX), NULL, DialogProc1, (LPARAM)&mmb);
    return -1;
}

#define D_TipBox TipBox

如上的代码使用TipBox(NULL,"文字","标题",NULL);就可以显示如下窗口了

但是这个是基于对话框的但我现在想用我13楼发的代码做一个文本编辑器,用一个新的窗口(什么样的都好,但是不要用通用控件,在对话框实现那串代码也好) 可以做出来吗

#define WS_VISIBLE 0x10000000L 没有？ ShowWindow（SW_SHOW);

SW_SHOW还是显示不了是要把LRESULT换成INT_PTR?

自己写个 edit 不容易，包括中英文·

代码已经在帖子上面了,只需要讨论怎么显示这个窗口那这样的话如上代码,改为

int Tip TextEdit(
    HWND hWnd,          // handle 
    LPWSTR lpText,     // text 
    LPWSTR lpCaption,  // title 
    UINT uType          // style 
)
{
    MMB_PARAM mmb;
    mmb.hWnd = hWnd;
    mmb.lpText = lpText;
    mmb.lpCaption = lpCaption;
    mmb.uType = uType;
    /*
    DialogBoxParam((HINSTANCE)GetWindowLong(hWnd, GWL_HINSTANCE),
        MAKEINTRESOURCE(IDD_TIPBOX), NULL, DialogProc1, (LPARAM)&mmb);
*/
    return -1;
}

就是用CreateWindow(szAppName, TEXT("Typing Program") 替换掉DialogParam就可以了吗

点击时 hwnd = CreateWindow(szAppName, TEXT("Typing Program"),。。

你把注册代码删除了？
你可以与主窗口调试注册这个窗口

wndclass.lpfnWndProc = xxxxxxProc; wndclass.lpszClassName = xxxxxx 注册类的时候指定不同的 lpfnWndProc 和 lpszClassName, CreateWindow 的时候用这个注册的类名即可

意思也不是子窗口,是以条件显示的比如点击按钮才显示之前就是一个类似的内置窗口例子:

    static HBITMAP hBitmap;                  // 1 静态变量
    static HBITMAP hBitmap2;
    static HBITMAP hBitmap3;

    BITMAP         bitmap;
    static HWND close;
    HDC hdcMem = NULL;
    static int      bmWidth, bmHeight;       // 2 静态变量
    char txt[40];

}

#define D_TipBox TipBox

调用方法是 TipBox(NULL,"TXT","TITLE",NULL)即可就是想像这个一样调用只不过,上面那个是对话框,现在我想创建一个纯窗口而已

请问我需要在按下"编辑器"按钮的时候打开这个窗口,该如何做呢?

case IDC_BUTTON:
                MessageBox(NULL, NULL, NULL, NULL);
                //在这里打开文本编辑器

主要是这样

引用 3 楼 schlafenhamster 的回复:

你也可以用对话框（放一个 edit）。点击时 popup 出来

想多注册一个类的原因主要还是通用对话框限制很大,WM_SIZE之类的消息处理不了,改变难度太大了... 所以才决定自己新创建一个窗体,和WindowProc一样进行改变,绘制. "总之,上面的代码是可以做成一个单独的exe的,只是想把这个代码合并到一个应用里面而已"

不想用通用控件实现,限制太大了. 总之,上面的代码是可以做成一个单独的exe的,只是想把这个代码合并到一个应用里面而已
