一個個人覺得還算好用的檔案管理工具兼文字編輯器(文字編輯的功能算是差強人意)

安裝指令：

yum -y install mc

使用指令：

由於本人在嘗試安裝軟體時缺了一些東西，便用yum下載

yum install -y ld-linux.so.2

-y 表示過程中不詢問，直接yes給過

ld-linux.so.2是我要裝的東西

================

會要設定精準的寬度是因為後面static text後面有時候要接Edit control

如果寬度設定不夠精準就會發生離很遠的情況

正常會先用方法1，如果後面不放其他控制項的話作為設定寬度就夠了

如果後面要放控制項就會用方法2

char[]轉成char*

參考網址：http://stackoverflow.com/questions/9627962/is-it-possible-to-convert-char-to-char-in-c

最簡單方法(wchar_t也適用)

method1:
char a[] = "hello";  
char* p = &a[0];

method2:(避免method1的值一出scope就消失)
char a[] = "hello"; 
char* p;
p = strdup(a);

使用完需release

如下

wchar_t *wchar;
char *ch = SSHUtil::ConvertWcsToMbs(wchar);

取得時間(目前僅在MFC用過可以，其他的沒試過)

CString csDate, csTime; // CString 只有在MFC裡面有

LPSYSTEMTIME time = new SYSTEMTIME;
::GetLocalTime(time);

// 結構
typedef struct _SYSTEMTIME {
    WORD wYear;
    WORD wMonth;
    WORD wDayOfWeek;
    WORD wDay;
    WORD wHour;
    WORD wMinute;
    WORD wSecond;
    WORD wMilliseconds;
} SYSTEMTIME, *PSYSTEMTIME;

// 簡易用法
csDate.Format(L"%04d/%02d/%02d", time->wYear, time->wMonth, time->wDay);
csTime.Format(L"%02d:%02d:%02d", time->wHour, time->wMinute, time->wSecond);

    // create dir (if dir doesn't exist)
    // dst是full path
    for ( int i = 3, cur = 3; i < dst.GetLength(); i++ ) { // 3是因為有"C:\"，把C槽本身當作一個資料夾
        if ( dst.GetAt(i) == L'\\' ) {
            if (!CFile::GetStatus(dst.Left(i), filestatus) ) // 判斷當前路徑如果不存在
                if ( !CreateDirectory(dst.Left(i), NULL) ) // 如果建立資料夾失敗
                    MessageBox(NULL,L"create dir fail!",L"ppppppppp",MB_OK);
        } // end if
    }

MFC內ListBox並不會自動顯示水平捲軸，除非當你設定項目的長度超過ListBox的寬度，

因此下列做法是先記錄最大長度，超過最大長度再來設定水平捲軸

參考自：https://msdn.microsoft.com/zh-tw/library/1s0xed6b.aspx

    int max_length = 0;
    for ( int i = 0; i < m_vecFileList.size(); i++ ) {
        m_ListFileName.AddString(m_vecFileList[i].c_str());

        // 當超過最大長度時
        if ( m_vecFileList[i].length() > max_length ) {
            max_length = m_vecFileList[i].length();

            
            CString    str;
            CSize      sz;
            int      dx = 0;
            TEXTMETRIC tm;
            CDC*       pDC = m_ListFileName.GetDC();
            CFont*     pFont = m_ListFileName.GetFont();
            // Select the listbox font, save the old font
            CFont* pOldFont = pDC->SelectObject(pFont);
            // Get the text metrics for avg char width
            pDC->GetTextMetrics(&tm); 

            for (int k = 0; k < m_ListFileName.GetCount(); k++) // 這裡面加總該item所有字元長度
            {
                m_ListFileName.GetText(k, str);
                sz = pDC->GetTextExtent(str);

                // Add the avg width to prevent clipping
                sz.cx += tm.tmAveCharWidth;

               if (sz.cx > dx)
            dx = sz.cx;

                }
            // Select the old font back into the DC
            pDC->SelectObject(pOldFont);
            m_ListFileName.ReleaseDC(pDC);

            // Set the horizontal extent so every character of all strings 
            // can be scrolled to.
            m_ListFileName.SetHorizontalExtent(dx);
            // should attention about listbox Hscrollbar length
        }

Progress Bar的使用

// set progress position

int tmp = 0; // tmp 0~100
SendMessage(it_tmp->pDialog->get_hProgress(), PBM_SETPOS, (WPARAM)tmp, 0);

ListBox的使用

// ListBox::AddString(加在最下面
SendMessage( hList, LB_ADDSTRING, 0, (LPARAM)L"123321"); 

// ListBox::InsertString(加在最上面
SendMessage( hList, LB_INSERTSTRING, 0, (LPARAM)L"123321"); 

// ListBox::DeleteString
SendMessage( hList, LB_DELETESTRING, 0, 0 ); 

// get 現在listbox的欄位總數
int n = SendMessage(tmp_hErrMsgList,LB_GETCOUNT, 0, 0) 

// 設定直的捲軸的位置在那個項目(n-1)上
SendMessage( hList, LB_SETTOPINDEX, n-1, 0); 

        #include <fstream>
    std::wstring wstrErrMsgDump = L"jiji\n1023=\nuhfizld\nhare\nrbgya\nazerreag\n123123123123\n45645645646\n";
    char c[500];
    memset (c,'\0',500);

    std::fstream fp;
    fp.open("test.csv", std::fstream::out);//開啟檔案的寫入功能 http://www.cplusplus.com/reference/fstream/fstream/open/
    if(!fp){MessageBox(L"file open error");}


    for ( int i = 0, c_index = 0; i < wstrErrMsgDump.length(); i++, c_index++ ) {
        if ( wstrErrMsgDump[i] != L'\n' ) {
            c[c_index] = wstrErrMsgDump[i];
        } // end if
        else if( wstrErrMsgDump[i] == L'\n' ) {

#include <vector>
//using namespace std; 
// 若前面沒using namespace std;時，後面宣告vector時皆需要加std:: 


// 在後方加入元素：v.push_back(i); 
// 刪除最後元素：v.pop_back(); 
// 檢查是否為空：v.empty(); 
// 直接將v清空 ：v.clear(); 
// 取得目前vector大小：v.size(); 
// 清除指定元素：v.erase(v.begin()+1); v.erase(v.end()-1); 
// v.begin() 表示為第0個元素，等同於 v[0] 
// v.end() 表示為最後一個元素，等同於 v[v.size()-1] 


// 普通vector用法
    std::vector<int> v1; // 宣告每個元素型態為int的vector
    for ( int i = 0; i < 100; i++) // 在後方新增元素100次
