记不住却用常用的代码

ASCII和Unicode互转

• 记得使用完delete空间

//ASCI -> Unicode
wchar_t* trans(const char * ch, int type = CP_ACP) {
	int len = MultiByteToWideChar(type, 0, ch, -1, nullptr, 0);
	wchar_t *str = new wchar_t[len + 1];
	wmemset(str, 0, len + 1);
	MultiByteToWideChar(type, 0, ch, -1, str, len);
	return str;
}

//Unicode -> ASCI
// 当type为CP_ACP时，UNICODE转化为GBK；当type为CP_UTF8时，UNICODE转化为UTF8  
char* trans(const wchar_t * wch, int type = CP_ACP) {
	int len = WideCharToMultiByte(type, 0, wch, -1, nullptr, 0, nullptr, nullptr);
	char *str = new char[len + 1];
	memset(str, 0, len + 1);
	WideCharToMultiByte(type, 0, wch, -1, str, len, nullptr, nullptr);
	return str;
}

获取当前工作路径

//获取当前工作路径
CString GetModuleDir()
{
    HMODULE module = GetModuleHandle(0);
    char pFileName[MAX_PATH];
    GetModuleFileName(module, pFileName, MAX_PATH);

    CString csFullPath(pFileName);
    int nPos = csFullPath.ReverseFind(_T('\\'));
    if (nPos < 0)
    {
        return CString("");
    }
    else
    {
        return csFullPath.Left(nPos);
    }
}

MFC 自动对齐listcontrol

//自动对齐listcontrol
void AdjustWidth(CListCtrl* pLst)
{
    //自适应宽度
    CHeaderCtrl* pCtlHeader = pLst->GetHeaderCtrl();
    int nColumnCount = pCtlHeader->GetItemCount();

    for (int i = 0; i < nColumnCount; i++)
    {
        pLst->SetColumnWidth(i, LVSCW_AUTOSIZE_USEHEADER);
    }
}
//设置listcontrol风格
m_lstcGDT.SetExtendedStyle(LVS_EX_GRIDLINES | LVS_EX_ONECLICKACTIVATE | LVS_EX_FULLROWSELECT);

C语言 各种进制转换

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <locale.h>
int main() {
    int i,v;
    char bs[33];
    char b[33];
    char hs[9];
    char h[9];
    char s[4];
    char *e;

// 十进制整数转二进制串；
    i=1024;
    ltoa(i,b,2);
    sprintf(bs,"%032s",b);
    printf("i=%d,bs=%s\n",i,bs);
// 十进制整数转十六进制串；
    i=1024;
    ltoa(i,h,16);
    sprintf(hs,"%08s",h);
    printf("i=%d,hs=%s\n",i,hs);
// 十六进制字符串转成十进制数
    strcpy(hs,"00000400");
    sscanf(hs,"%x",&i);
    printf("hs=%s,i=%d\n",hs,i);
// 二进制字符串转化为十六进制字符串；
    strcpy(bs,"00000000000000000000010000000000");
    i=strtol(bs,&e,2);
    ltoa(i,h,16);
    sprintf(hs,"%08s",h);
    printf("bs=%s,hs=%s\n",bs,hs);
// 二进制字符串转化为十进制数；
    strcpy(bs,"00000000000000000000010000000000");
    i=strtol(bs,&e,2);
    printf("bs=%s,i=%d\n",bs,i);
// 十六进制字符串转成二进制串
    strcpy(hs,"00000400");
    sscanf(hs,"%x",&i);
    ltoa(i,b,2);
    sprintf(bs,"%032s",b);
    printf("hs=%s,bs=%s\n",hs,bs);
// ASC\GBK字符串转十六进制串
    strcpy(s,"a汉");
    i=0;
    while (1) {
        if (0==s[i]) break;
        sprintf(hs+i*2,"%02X",(unsigned char)s[i]);
        i++;
    }
    setlocale(LC_ALL,"chs");
    printf("s=%s,hs=%s\n",s,hs);
// 十六进制字符串转成汉字（GBK）及字符(ASC)
    strcpy(hs,"61BABA");
    i=0;
    while (1) {
        if (1!=sscanf(hs+i*2,"%2x",&v)) break;
        s[i]=(char)v;
        i++;
    }
    s[i]=0;
    printf("hs=%s,s=%s\n",hs,s);

    return 0;

}

C语言字符串分割

char* strSplit()
{
char str[] = "now # is the time for all # good men to come to the # aid of their country";
   char delims[] = "#";
   char *result = NULL;
   result = strtok( str, delims );
   while( result != NULL ) {
       printf( "result is \"%s\"\n", result );
       result = strtok( NULL, delims );
}
