C Win32api,创建一个没有资源的对话框

前端之家收集整理的这篇文章主要介绍了C Win32api,创建一个没有资源的对话框前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我是win32api编程的新手.我想知道如何在非gui程序中创建一个对话框(没有任何资源创建).

我看到有一些CreateIndirect函数的例子.这是最好的方法吗?有什么办法吗

谢谢!

解决方法

您将使用 DialogBoxIndirectParamCreateDialogIndirectParam

通过这些功能,它有更多的工作,但是可以在代码中嵌入一个简单的对话框模板作为一个初始化的静态结构体.对话框模板的格式有一些内置可变大小的数组,因此您必须具有特定于特定对话框的结构声明,但这对调试代码起作用.

这样的东西

#define DLGTITLE  L"Debug"
#define DLGFONT   L"MS Sans Serif"
#define DLGAPPLY  L"&Apply"
#define DLGCANCEL L"&Cancel"
#define NUMCHARS(aa) (sizeof(aa)/sizeof((aa)[0]))
#define IDC_BITMAP 99

#pragma pack(push,4)                 
static struct { // dltt 

    DWORD  style; 
    DWORD  dwExtendedStyle;

    short  cy; 
    WORD   menu;         // name or ordinal of a menu resource
    WORD   windowClass;  // name or ordinal of a window class
    WCHAR  wszTitle[NUMCHARS(DLGTITLE)]; // title string of the dialog Box
    short  pointsize;       // only if DS_SETFONT flag is set
    WCHAR  wszFont[NUMCHARS(DLGFONT)];   // typeface name,if DS_SETFONT is set

    // control info

    } apply;

    struct {
       DWORD  style; 
       DWORD  exStyle; 
       short  x;

#pragma pack(pop)

INT_PTR CALLBACK Debug_DlgProc (
    HWND   hwnd,UINT   uMsg,WPARAM wParam,LPARAM lParam)
{
    switch (uMsg)
       {
       case WM_INITDIALOG:
           {
           }
           break;

       case WM_COMMAND:
           {
           UINT wId = LOWORD(wParam);
           if (wId == IDOK || wId == IDCANCEL)
              {
              EndDialog (hwnd,wId);
              }
           }
           break;

       case WM_CLOSE:
           EndDialog(hwnd,IDCANCEL);
           break;
       }

    return FALSE;
}


LRESULT DoDebugDialog(HWND hwndApp,LPVOID pvData)
{
   HINSTANCE hinst = hwndApp ? (HINSTANCE)(LONG_PTR)GetWindowLongPtr(hwndApp,GWLP_HINSTANCE) 
                             : (HINSTANCE)GetModuleHandle(NULL);

   return DialogBoxIndirectParamW (hinst,(LPCDLGTEMPLATEW)&g_DebugDlgTemplate,hwndApp,Debug_DlgProc,(LPARAM)pvData);
}

更复杂的解决方案是在内存中建立一个对话框模板结构,但是对于调试代码,对话框本身并没有太大变化,这样做很好.
