自定义void，怎样给编辑框显示数字？
m_roleblood是编辑框变量。
只有这么多，前面也没有任何初始化。
void CALLBACK RoleBlood(
HWND hwnd, // handle of window for timer messages
UINT uMsg, // WM_TIMER message
UINT idEvent, // timer identifier
DWORD dwTime // current system time
)
{
char s[30];
int * pBlood=(int *)BloodBase;
itoa(* pBlood,s,10);
SetWindowText(m_roleblood.m_hWnd,s);
//错误：'m_roleblood' : undeclared identifier
//错误：'.m_hWnd' must have class/struct/union type
}
const int RoleBloodCheckID=238;
void WGForm::OnRoleblood()
{
// TODO: Add your control notification handler code here
UpdateData(true);
if(m_rolebloodcheck)
{
SetTimer(RoleBloodCheckID,500,&RoleBlood);
}
else
{
KillTimer(RoleBloodCheckID);
}
}
[解决办法]m_roleblood.SetWindowText(s);
[解决办法]SetWindowText
The SetWindowText function changes the text of the specified window's title bar (if it has one). If the specified window is a control, the text of the control is changed. However, SetWindowText cannot change the text of a control in another application.
BOOL SetWindowText(
HWND hWnd, // handle to window or control
LPCTSTR lpString // address of string
);
Parameters
hWnd
Handle to the window or control whose text is to be changed.
lpString
Pointer to a null-terminated string to be used as the new title or control text.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, callGetLastError.
Remarks
If the target window is owned by the current process, SetWindowText causes a WM_SETTEXT message to be sent to the specified window or control. If the control is a list box control created with the WS_CAPTION style, however, SetWindowText sets the text for the control, not for the list box entries.
The SetWindowText function does not expand tab characters (ASCII code 0x09). Tab characters are displayed as vertical bar (
[解决办法]) characters.
