HBITMAP ,, HBITMAP =, (HBITMAP):: SHLoadDIBitmap (szBitmapFile); 五,要以共享MFC的DLL库的方式发布程序,须将如下目录中DLL全部复制到目标机器上。
C: \ Program Files (x86) \ Microsoft Visual Studio 8 \ VC \ ce \ DLL \ armv4i 六,wchar_t *转char *
如,sCaption为LPCTSTR类型字符串,要转成char *字符串,如下:
int num =, WideCharToMultiByte (CP_OEMCP, NULL,, sCaption,, 1,,空,,0,,空,,假);
char * pChar =, new char (num);
WideCharToMultiByte (CP_OEMCP, NULL,, sCaption,, 1,, pChar,, num,,空,,假), 七,字体平滑,需要修改注册表
HKEY_LOCAL_MACHINE \ \系统\ \ GDI \ \ ClearType
默认=2 八,不关闭屏幕,常期显示工作界面
//电源参数请求更新
HANDLE hevReloadActivityTimeouts =,, OpenEvent (EVENT_ALL_ACCESS,,假的,
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,_T (“PowerManager/ReloadActivityTimeouts"));
if (hevReloadActivityTimeouts),
{
SetEvent (hevReloadActivityTimeouts);
CloseHandle (hevReloadActivityTimeouts);
} 同时,在注册表中也要修改超时设置。
九,Sqlite数据库读写
void CSimpleModeData:: TempTableWrite (CString CarNo CString strWeight, CString GoodsName,,
CString 时间)
{
,,,CString str ;
str.Format (_T (“insert into SimpleModeTempTable (CarNo, GoodsName、重量、时间)\
,,值(& # 39;% & # 39;& # 39;% & # 39;,& # 39;% & # 39;,& # 39;% & # 39;)“),CarNo, strWeight, GoodsName,
时间才能);
跟踪(str);
m_sqliteDB.execQuery (str);
}
BOOL CSimpleModeData:: TempTableRead (CString strCarNo)
{
CString str ;
str.Format (_T (“select *,得到SimpleModeTempTable where CarNo =, & # 39; % & # 39;“));
跟踪(str);
CppSQLite3Query , query =, m_sqliteDB.execQuery (str);
,,,如果(! query.eof ())
{
20岁的wcscpy_s (CGlobal:: g_TempTable.CarNo query.fieldValue (1));
,,,,,,,wcscpy_s (CGlobal:: g_TempTable.GoodsName, 20,, query.fieldValue (2));
,,,,,,,wcscpy_s (CGlobal:: g_TempTable.Weight 20 query.fieldValue (3));
return 真实;
}
query.finalize ();
,,,return 假;
} 十,软件重启
# include “windows.h"
# include “winioctl.h"
# define POWER_STATE_RESET ,,,,,,(字)(0 x00800000)
# define POWER_FORCE ,,,,,,,,,,,,(字)(0 x00001000)
