大家快来强分!怎么把字符串" 255, 255, 255 "转换为RGB(255,255,255)???

[cident]

如果中间有空格也需要考虑进去?
听说用boost库很容易解决?哪位大虾愿意示范一下?

[seaiam]

char chArry[]="255,255,255\0";
int nIndex=0;
int nNumberIndex=0;
BYTE bArry[3];
BYTE bTemp=0;
while(chArry[nIndex]!='\0')
{
if(chArry[nIndex]>='0'&&chArry[nIndex]<='9')
{
bTemp=bTemp*10+(chArry[nIndex]-'0');
}
else
{
bArry[nNumberIndex++]=bTemp;
bTemp=0;
}
nIndex++;

}
COLORREF coResult=RGB(bArry[0],bArry[1],bArry[2]);

顶,请各位继续...

这么简单就不用boost库了
char buff[]=" 255, 255, 255 ";
int r,g,b;
sscanf(buff,"%d,%d,%d",&r,&g,&b);
COLORREF coResult=RGB(r,g,b);

这样也可以
char input[] = "255, 255 ,255";
char *p;
int ar[3],i=0;

p = strtok(input, ", ");
while(p)
{
ar[i++]=atoi(p);
p = strtok(NULL, ", ");
}
COLORREF coResult=RGB(ar[0],ar[1],ar[2]);

fuc(const char* szgbr)
{
char* sztemp = szgbr;
for(i = 0; i++; i< strlen(szgbr))
{
if(',' == sztemp[i] || ' ' == sztemp[i])
{
sztemp[i] = '\n';
}
}
sztemp = szgbr;
g = strtoul(sztemp);
sztemp += strlen(sztemp)+1;
b = strtoul(sztemp);
sztemp += strlen(sztemp)+1;
r = strtoul(sztemp);
sztemp += strlen(sztemp)+1;
return RGB(g,b,r);
}

用boost的两种方法
1.
regex H1(" *(\\d{3}).*(\\d{3}).*(\\d{3})");
char input[] = "255, 255 ,255";
cmatch what;
if(regex_match(input,what,H1))
{
int r= atoi((what[1].str()).c_str());
int g= atoi((what[2].str()).c_str());
int b= atoi((what[3].str()).c_str());
}

2.
regex H1(" *, *");
string s = "255, 255 ,255";

vector<string> what;

regex_split(back_inserter(what),s,H1);
int r= atoi(what[0].c_str());
int g= atoi(what[1].c_str());
int b= atoi(what[2].c_str());

不需要使用正则表达式也可以的。下面是一种方法：

char szBuf[] = "255,255,255\0";
int nRed = 0, nGreen = 0, nBlue = 0;
sscanf(szBuf, "%d,%d,%d", &nRed, &nGreen, &nBlue);
COLORREF clr = RGB(nRed, nGreen, nBlue);

[cident]

如果通过',' 来分割字符串呢?

[cident]

void get_private_info(const string& strInfo, string& strCompany, string& strDepartment, string& strEmail)
{
boost::regex r1(" *, *");
vector<string> what;

boost::regex_split(back_inserter(what), strInfo, r1);
}
这便一同不过。

1.你安装boost了吗?(vc本身没有的)
2.头文件:
#include <string>
#include <boost\regex.hpp>
#include <boost\current_function.hpp>
#include <vector>
using namespace boost;
using namespace std;

[柯本]

我上面的
C函数:p = strtok(input, ",");// 可以 (加空格可以去空格", ")
boost 的regex H1(","); //regex H1(" *, *");可以去空格
regex_split(back_inserter(what),s,H1); 也可以

char szBuf[] = "255,255,255\0";
int nRed = 0, nGreen = 0, nBlue = 0;
sscanf(szBuf, "%d,%d,%d", &nRed, &nGreen, &nBlue);
COLORREF clr = RGB(nRed, nGreen, nBlue);

高手。
