创建对话框

首选需要创建一个对话框

所以应该包含resource.h资源文件

.h 文件：

struct DecodeUint{
 UINT meesage;
 LONG (*fun)(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);
};

#define dim(x) (sizeof(x)/sizeof(x[0]))

LONG OnInit(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
LONG OnCommand(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
LONG OnClose(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);

BOOL CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);

 

.c文件：

#include <windows.h>
#include <windowsx.h>
#include <CommCtrl.h>
#include <wingdi.h>
#include "Border.h"
#include "resource.h"

struct DecodeUint DlgMessage[] = {
 WM_INITDIALOG,OnInit,
 WM_COMMAND,OnCommand,
};

struct DecodeUint DlgCommand[] = {
 IDOK,OnClose,
 IDCANCEL,OnClose,
};


LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);

int WinMain(HINSTANCE hInstance,
   HINSTANCE hPrevInstance,
   LPTSTR    lpCmdLine,
   int       nCmdShow)
{
 DialogBox(hInstance,MAKEINTRESOURCE(IDD_DIALOG1),NULL,About);
 return 1;
}

BOOL CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    for (int i = 0;i < dim(DlgMessage);i ++)
    {
  if (DlgMessage[i].meesage == message)
  {
   (*DlgMessage[i].fun)(hDlg,message,wParam,lParam);
  }
    }
 return FALSE;
}

LONG OnInit(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
 return TRUE;
}

LONG OnCommand(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
 for (int i = 0;i < dim(DlgCommand);i ++)
 {
  if (DlgCommand[i].meesage == LOWORD(wParam))
  {
   (*DlgCommand[i].fun)(hDlg,message,wParam,lParam);
  }
 }

 return TRUE;
}

LONG OnClose(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
 EndDialog(hDlg,0);
 return TRUE;
}
