resource.h中的内容怎么会不变呢?搞得跟代码无关似地
源码如下
#include<windows.h>
#include"resource.h"
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
BOOL CALLBACK AboutDlgProc (HWND, UINT, WPARAM, LPARAM) ;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("About1") ;
MSG msg ;
HWND hwnd ;
WNDCLASS wndclass;
wndclass.style = CS_HREDRAW | CS_VREDRAW ;
wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance ;
wndclass.hIcon = LoadIcon (hInstance, szAppName) ;
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
wndclass.lpszMenuName = szAppName ;
wndclass.lpszClassName = szAppName ;
if (!RegisterClass (&wndclass))
{
MessageBox (NULL, TEXT ("This program requires Windows NT!"),
szAppName, MB_ICONERROR) ;
return 0 ;
}
hwnd = CreateWindow (szAppName, TEXT ("About Box Demo Program"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL) ;
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL,0,0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
static HINSTANCE hInstance ;
switch (message)
{
case WM_CREATE:
hInstance = ((LPCREATESTRUCT) lParam)->hInstance ;
return 0 ;
case WM_COMMAND :
switch (LOWORD (wParam))
{
///////////////////////////////////////////////////////////////////////////////////////
case IDM_APP_ABOUT :
DialogBox (hInstance, TEXT ("AboutBox"), hwnd, AboutDlgProc) ;
break ;
}
return 0 ;
case WM_DESTROY :
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}
BOOL CALLBACK AboutDlgProc (HWND hDlg, UINT message,WPARAM wParam,
LPARAM lParam)
{
switch (message)
{
case WM_INITDIALOG :
return TRUE ;
case WM_COMMAND :
switch (LOWORD (wParam))
{
case IDOK :
case IDCANCEL :
EndDialog (hDlg, 0) ;
return TRUE ;
}
break ;
}
return FALSE ;
}
编译后说resource.h未创建,我通过新建-资源脚本创建了resource,
打开文件夹发现有resource.h和.rc文件,但用记事本打开resource.h文件时
发觉其内容只有
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
// Used by dialogbox.rc
//
// Next default values for new objects
//
#ifdef APSTUDIO_INVOKED
#ifndef APSTUDIO_READONLY_SYMBOLS
#define _APS_NEXT_RESOURCE_VALUE 101
#define _APS_NEXT_COMMAND_VALUE 40001
#define _APS_NEXT_CONTROL_VALUE 1000
#define _APS_NEXT_SYMED_VALUE 101
#endif
#endif
并没有关于IDM_APP_ABOUT 等的定义,在.rc文件中也看不到About等代码,
而且发觉这两个文件里的内容和以前的一样,好像和我现在编的代码无关一样。
我在resource.h中添加了#define IDM_APP_ABOUT 100后,编译可以通过,
也有窗口产生,但就是没有对话框,和书上现实的不同(《windows 程序设计》)
新人求指教!!!!
