overloaded member function 'void (unsigned int)' not found in

[liuyang1943]

我在demoView.h中如下定义：
lass CDemoView : public CView
{
protected: // create from serialization only
afx_msg void OnTimer(UINT_PTR nIDEvent);
CDemoView();
DECLARE_DYNCREATE(CDemoView)
...
.....

然后在demoView.cpp中：
IMPLEMENT_DYNCREATE(CDemoView, CView)

BEGIN_MESSAGE_MAP(CDemoView, CView)
//{{AFX_MSG_MAP(CDemoView)
// NOTE - the ClassWizard will add and remove mapping macros here.
// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
// Standard printing commands
ON_WM_TIMER()
ON_COMMAND(ID_FILE_PRINT, CView::OnFilePrint)
ON_COMMAND(ID_FILE_PRINT_DIRECT, CView::OnFilePrint)
ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview)
END_MESSAGE_MAP()
...
...
void CDemoView::OnTimer(UINT nIDEvent)

{

// TODO: Add your message handler code here and/or call default

pBackDC->PatBlt(0,0,winx, winy, PATCOPY);

//画坐标轴及刻度

DrawCoordinate(pBackDC ,BLACKPEN, MainWindowLeft,MainWindowBottom - MAINHEIGHT, MainWindowLeft + MAINWIDTH, MainWindowBottom);

//标出x坐标刻度值

WriteCoordinateX(pBackDC, BLACKPEN, MainWindowLeft,MainWindowLeft + MAINWIDTH, MainWindowBottom);
...
...

红色部分是错误代码，错误提示为：error C2511: 'OnTimer' : overloaded member function 'void (unsigned int)' not found in 'CDemoView'
f:\lcd驱动开发\图形编程\demo\demoview.h(13) : see declaration of 'CDemoView'
啥原因呢？高手指点下。。

OnTimer函数在你的头文件和CPP中定义的参数类型不一致

[快乐鹦鹉]

头文件：afx_msg void OnTimer(UINT_PTR nIDEvent);
CPP:void CDemoView::OnTimer(UINT nIDEvent)
都改成UINT就行

[江川]

afx_msg void OnTimer(UINT_PTR nIDEvent);
改成
afx_msg void OnTimer(UINT nIDEvent);

[hongya6088]

afx_msg void OnTimer(UINT_PTR nIDEvent); 和 void CDemoView::OnTimer(UINT nIDEvent) 参数不一致！

多谢各位，刚我也遇到了相同的问题。
