用了一個星期，終於把掃雷做的差不多了，其中遇到很多很多問題，但慢慢解決了，確實挺令人高興，也許這就是編程的魅力所在吧。
下面記錄掃雷的主要幾個算法：
一：布雷
1 void CMineButton::Reset(CWnd* pParent)//參考與小張上傳中的程序，，對butto進行初始化
2 {
3
4 CMINEMFCApp *app = (CMINEMFCApp *)AfxGetApp();
5
6 app->m_pParent = pParent;
7
8 int nI;
9
10 for(nI=0;nI<100;nI++)
11 {
12 if (app->m_aLandMine[nI]!=NULL)
13 delete app->m_aLandMine[nI];
14 }
15 for(nI=0;nI<100;nI++)
16 {
17
18 app->m_aLandMine[nI] = new CMineButton;
19
20 }
21
22
23 int nCurMines=0;
24 int nCurMine;
25 int curi = 0;
26 srand( (unsigned)time( NULL ));
27
28 while(nCurMines<10)
29 {
30 nCurMine=rand()%(100);//獲取10個雷的分布
31 (app->m_theRealMine[curi]) = nCurMine;
32 if(app->m_aLandMine[nCurMine]->GetMineNum() != -1)//該寫法的作用是初始化10個雷周圍button的雷的數量
33 {
34 app->m_aLandMine[nCurMine]->SetMineNum(-1);
35 int nMineRound,nMineRound1;
36 //right;
37 nMineRound = app->m_aLandMine[nCurMine]->GetRight(nCurMine);
38 if(nMineRound>=0)
39 {
40 if (app->m_aLandMine[nMineRound]->GetMineNum() != -1)
41 ++(*app->m_aLandMine[nMineRound]);
42 //right top
43 nMineRound1 = (app->m_aLandMine[nMineRound]->GetTop(nMineRound));
44 if(nMineRound1>=0 && app->m_aLandMine[nMineRound1]->GetMineNum() != -1)
45 {
46 ++(*app->m_aLandMine[nMineRound1]);
47 }
48 //right bottom
49 nMineRound1 = app->m_aLandMine[nMineRound]->GetBot(nMineRound);
50 if(nMineRound1>=0 && app->m_aLandMine[nMineRound1]->GetMineNum() != -1)
51 {
52 ++(*app->m_aLandMine[nMineRound1]);
53 }
54 }
55 //left
56 nMineRound = app->m_aLandMine[nCurMine]->GetLeft(nCurMine);
57 if(nMineRound>=0)
58 {
59 if(app->m_aLandMine[nMineRound]->GetMineNum() != -1)
60 ++(*app->m_aLandMine[nMineRound]);
61
62 //Left top
63 nMineRound1 = app->m_aLandMine[nMineRound]->GetTop(nMineRound);
64 if(nMineRound1>=0 && app->m_aLandMine[nMineRound1]->GetMineNum() != -1)
65 {
66 ++(*app->m_aLandMine[nMineRound1]);
67 }
68
69 //Left bottom
70 nMineRound1 = app->m_aLandMine[nMineRound]->GetBot(nMineRound);
71 if(nMineRound1>=0 && app->m_aLandMine[nMineRound1]->GetMineNum() !=分公司的72 {
73 ++(*app->m_aLandMine[nMineRound1]);
74 }
75 }
76 //Top
77 nMineRound = app->m_aLandMine[nCurMine]->GetTop(nCurMine);
78 if(nMineRound>=0 && app->m_aLandMine[nMineRound]->GetMineNum() != -1)
79 {
80 ++(*app->m_aLandMine[nMineRound]);
81 }
82
83 //Bottom
84 nMineRound = app->m_aLandMine[nCurMine]->GetBot(nCurMine);
85 if(nMineRound>=0 && app->m_aLandMine[nMineRound]->GetMineNum() != -1)
86 {
87 ++(*app->m_aLandMine[nMineRound]);
88 }
89 nCurMines++;
90 curi ++ ;
91 }
92 }
93 }
二：空白雷區的實現
BOOL CMINEMFCDlg::RecordMine(int nCurMine)//也是根據另一個程序打開空白的周圍的算法，，是一個循環隊列的使用
{ CMINEMFCApp *app = (CMINEMFCApp *)AfxGetApp(); int nRoundMine,nRoundMine1; int aMine[500]; int nTop=0,nTail=0; aMine[nTop++] = nCurMine; while(nTop!=nTail) { int nCurrent=aMine[nTail]; nTail = (nTail+1)%500; switch((app->m_aLandMine[nCurrent])->OpenMine(nCurrent)) { case 0: // Mine number is zero
nRoundMine = (app->m_aLandMine[nCurrent])->GetLeft(nCurrent); if(nRoundMine!=-1) { aMine[nTop] = nRoundMine; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); if(nRoundMine1!=-1) { aMine[nTop] = nRoundMine1; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); } nRoundMine1 = (app->m_aLandMine[nCurrent])->GetBot(nRoundMine); if(nRoundMine1!=-1) { aMine[nTop] = nRoundMine1; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); } } nRoundMine = (app->m_aLandMine[nCurrent])->GetRight(nCurrent); if(nRoundMine!=-1) { aMine[nTop] = nRoundMine; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); if(nRoundMine1!=-1) { aMine[nTop] = nRoundMine1; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); } nRoundMine1 = (app->m_aLandMine[nCurrent])->GetBot(nRoundMine); if(nRoundMine1!=-1) { aMine[nTop] = nRoundMine1; nTop = (nTop+1)%500; nRoundMine1 = (app->m_aLandMine[nCurrent])->GetTop(nRoundMine); } } nRoundMine = (app->m_aLandMine[nCurrent])->GetTop(nCurrent); if(nRoundMine!=-1) { aMine[nTop] = nRoundMine; nTop = (nTop+1)%500; } nRoundMine = (app->m_aLandMine[nCurrent])->GetBot(nCurrent); if(nRoundMine!=-1) { aMine[nTop] = nRoundMine; nTop = (nTop+1)%500; } break; case 1: break; case -1: return FALSE; // fail
} } return TRUE; }
下面講講自己遇到的一些困難和新get的技能吧：
1，invalidate函數
Invalidate()之后：（MFC的，順便了）
OnPaint()->OnPrepareDC()->OnDraw()
所以只是刷新在OnPaint()和OnDraw()函數中的繪圖語句。其它地方沒有影響。
Invalidate標記一個需要重繪的無效區域，並不意味着調用該函數后就立刻進行重繪。類似於PostMessage(WM_PAINT)，需要處理到WM_PAINT消息時才真正重繪。以為您Invalidate之后還有其他的語句正在執行，程序沒有機會去處理WM_PAINT消息，但當函數執行完畢后，消息處理才得以進行。
Invalidate只是放一個WM_PAINT消息在隊列里，不做別的，所以只有當當前函數返回后，進入消息循環，取出WM_PAINT，才執行PAINT，所以不管Invalidate放哪里，都是最后的。
其實我遇到了就是把drawbutton放在了onpaint里面，導致其不斷的刷新。。。。
invalidateRect是通過消息來調用OnPaint
RedrawWindow除了有InvalidateRect的效果，還會立即調用一次OnPaint（不經過消息隊列，類似 UpdateWindow），這個redrawwindow會立即調用ONpaint。
2.
解決 unresolved external symbol 無法解析 _send@16
這個一般都是lib庫沒有設置好而導致的。。

VC6.0常見錯誤之：:Debug Assertion Failed!
這個比較多，，發一個網址吧http://blog.csdn.net/xjkstar/article/details/6922259。

//聲明:
SetWindowPos(
hWnd: HWND; {窗口句柄}
hWndInsertAfter: HWND; {窗口的 Z 順序}
X, Y: Integer; {位置}

): BOOL;

SWP_ASYNCWINDOWPOS = $4000; {若調用進程不擁有窗口, 系統會向擁有窗口的線程發出需求}
//舉例: procedure TForm1.Button1Click(Sender: TObject); begin SetWindowPos(Handle, HWND_TOPMOST, 0,0, 100,200, SWP_SHOWWINDOW); end;
4，在鼠標右擊響應函數中這樣來寫
BOOL CMINEMFCDlg::PreTranslateMessage(MSG* pMsg) //對於右擊鼠標的響應
{ // TODO: Add your specialized code here and/or call the base class
CMINEMFCApp *app = (CMINEMFCApp *)AfxGetApp(); CClientDC dc(this); CFont font; font.CreateFont(20, 15, 0, 0, FW_SEMIBOLD, FALSE, FALSE, FALSE, 0, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_ROMAN, _T("新宋體")); CFont *pOldFont=dc.SelectObject(&font); dc.SetBkColor(RGB(237,237,237)); if(pMsg->message==WM_RBUTTONDOWN)//鼠標點擊右鍵
{ CRect rc; CPoint ptCursor; ::GetCursorPos(&ptCursor);//獲取鼠標的位置信息
int pos; for(pos=159;pos<259;pos++) { GetDlgItem(pos)-> GetWindowRect(&rc);//獲取控件的位置信息
if(PtInRect(&rc,ptCursor))//右鍵點擊位置在某一個控件上
{ CMineButtonVisual* pMineButton = (CMineButtonVisual*)GetDlgItem(pos); if(pMineButton->rButClickedFlags == 0) { SetDlgItemText(pos,"☆"); pMineButton->rButClickedFlags = (pMineButton->rButClickedFlags +1)%3; m_recordRealMine[m_recordRealMineFlags] = pos; m_recordRealMineFlags ++ ; CString str; str.Format("剩余雷數：%d",(10-m_recordRealMineFlags)); GetDlgItem(IDC_STATIC_MINENUM)->SetWindowText(str); } else if(pMineButton->rButClickedFlags == 1) { SetDlgItemText(pos,"?"); pMineButton->rButClickedFlags =(pMineButton->rButClickedFlags +1)%3; m_recordRealMineFlags -- ; CString str; str.Format("剩余雷數：%d",(10-m_recordRealMineFlags)); GetDlgItem(IDC_STATIC_MINENUM)->SetWindowText(str); } else { SetDlgItemText(pos," "); pMineButton->rButClickedFlags = (pMineButton->rButClickedFlags +1)%3; } //m_minenum--; //if(flg[pos-1000]==1) //mine[0]--;
} } if(m_recordRealMineFlags == 10) { int curflags = 0; for(int curj = 0;curj<m_recordRealMineFlags;curj++) for(int curi = 0;curi<10;curi++) { if (m_recordRealMine[curi] == (app->m_theRealMine[curj]+159)) { curflags ++ ; break; } } if(curflags == 10) { MessageBox("恭喜你！！！掃雷成功！！你碉堡了！！！"); bFail = 1; } } // GetDlgItem(1100)-> GetWindowRect(&rc);//獲取開始按鈕的位置信息
/*if(PtInRect(&rc,ptCursor))//右鍵點擊位置在某一個控件上 { for(int i=1;i<=mine[0];i++) { SetDlgItemText(mine[i]+1000,"*"); } }*/ } return CDialog::PreTranslateMessage(pMsg); }
5.ON_CONTROL_RANGE(BN_CLICKED, IDC_BUTTON1, IDC_BUTTON10, OnButtonClicked)的使用。
6.創建一個指針，，delete掉。
for(int curi = 0; curi < 100 ;curi++) { if(m_btn[curi]->m_hWnd != 0) { delete m_btn[curi]; m_btn[curi] = new CMineButtonVisual; } }
7.定時器的用法
settimer（1,1000，null）
ontimer（）則響應。
killtimer則銷毀settimer
最后附一張截圖，，紀念一下自己寫的第一個游戲。
