CString "31256"如何format成“31，256”这种形式？
CString.format里面如何写？

[freeinsky]

我觉的你可以这样

CString strTmp;
strTmp = "31256";
strTmp.Insert(2, ",");
就可以了

[Micro_Sheng]

自己写一个转换函数呀

信息不够
如果知道了长度也好说些。
如果长度不变则

CString str = "31256";
CString str1 = str.Left(2);
CString str2 = str.Right(3);
CString str3;

str3.Format("%s,%s",str1,str2);

[aspvbjava]

int tmp = 31256;
CString str;
str.Format("%d,%d",(int)(tmp/1000),tmp-((int)(tmp/1000))*1000);

CString FmtStringFromDW(DWORD n)
{
CString tmp;
char *ch = new char[20];
ultoa(n,ch,10);
tmp = CString(ch);
int size = tmp.GetLength();
int count = size%3;
count = count == 0 ? 3 : count;
int k=0;
for(int i=0;i<size;)
{
for(int j=0;j<count;j++)
{
ch[k++] = tmp[i++];
}
if(i<=size-1)
ch[k++] = ',';
count = 3;
}
ch[k] = '\0';
tmp = CString(ch);
delete[] ch;
return tmp;
}

ultoa是啥函数？msdn里面没有

[BitBlt]

format("123456789","#,#")
123,456,789

[mashaowuxyz]

楼上的format("123456789","#,#")
123,456,789
是怎么做的？我看不懂。

_ultoa, _ultow
Convert an unsigned long integer to a string.

char *_ultoa( unsigned long value, char *string, int radix );

wchar_t *_ultow( unsigned long value, wchar_t *string, int radix );
