Windows 随着对话框的增强/扩展，降低资源文件增长率的方法

作为扩展用C编写的旧Windows WinAPI GUI应用程序中对话框功能的一部分，我再次面临为六行数据输入对话框的每行添加多个复选框的问题。我无法忍受重复的资源文件和源代码文件更改带来的麻烦，决定借用JavaUI的UI设计方法，从窗格构建UI

VisualStudio工具（至少是VisualStudio2005）似乎不鼓励这种方法，在本例中，我手工编辑了资源文件。Visual Studio 2017的资源编辑工具可能更灵活

我的问题是，这种方法的替代方案是什么，它似乎同样容易做到，并且更符合VisualStudio的理念

我还想知道这种方法的缺点

对于困扰我的VisualStudioC WinAPI GUI应用程序来说，这种方法似乎不常见。我不能说自己特别有创新性，所以我想知道我遗漏了什么，因为这种方法似乎工作得很好，至少在手工编辑资源文件时是如此

我正在考虑进行另一次迭代，将重复出现的每一行的控件列表移动到无模式对话框模板中，并使原始对话框成为6个静态窗口的堆栈，每一行一个

这种方法的好处是定义更少，并且能够重用定义。将新功能插入现有的对话框行为源代码也更容易，尽管这主要是因为这些只是简单的自动复选框

我看到的一个问题是在进行此更改后使用VisualStudio工具。但是，这个特定应用程序的资源文件无论如何都不能与VisualStudio资源编辑工具配合使用

当我需要向无模式对话框模板添加一些额外的复选框时，这种方法已经有了回报。我要做的资源文件更改是在新对话框模板中添加额外的复选框，并调整原始对话框大小、无模式对话框大小和静态窗口的大小，以使所有内容都可见

实施

我实施的替代方案是：

• 使用一组复选框创建对话框模板
• 将无模式对话框的对话框模板样式修改为WS\u CHILD
• 为新对话框模板在原始对话框的六行中的每一行上创建一个静态窗口
• 在每行的静态窗口中放置无模式对话框的实例

对话框的新版本如下所示 当显示原始对话框时，init dialog消息的处理程序将创建一组六个无模式对话框，每个新添加的静态窗口一个，对话框的父窗口为静态窗口。这会将无模式对话框放置在静态窗口中，当静态窗口移动时，无模式对话框也会移动

static struct {
    int   iId;
    HWND  hWnd;

                                   A170DlgChildProc);
    hWnd && ShowWindow (hWnd, nCmdShow);
    for (i = 0; i < sizeof(A170DlgTabs)/sizeof(A170DlgTabs[0]); i++) {
        if (A170DlgTabs[i].hWnd == 0) {

        CheckDlgButton(hWnd, i, (usMask & k) ? TRUE : FALSE);
    }

    return usMask;
}

所有六个无模式对话框都使用相同的对话框消息处理程序。消息处理程序本身不处理任何消息

无模式对话框模板是：

您可能会注意到，我刚刚重用了新的无模式对话框中的一些定义，这些定义已经在原始对话框中使用。之所以能够这样做，是因为控件标识符特定于对话框本身。因此，在不同的对话框中使用相同的定义不会导致问题，因为使用

GetDlgItem（）

获取对话框中控件的窗口句柄需要特定对话框实例的窗口句柄

然后，我创建了一组帮助函数，用于处理无模式对话框的实例
