下面的字符串格式如何实现？

[babala2009]

字符串左对齐，日期右对齐

CString s;
s.Format("100.%, %s", "字符串"， "2009-7-8")

┏─────────────────────┓
│字符串字符串字符串...... 2009-7-8 │
│字符串...... 2009-7-8 │
│字符串字符串字符...... 2009-7-8 │
│字...... 2009-7-8 │
┗─────────────────────┛

左对齐在前面加"-",默认右对齐,加点没试过,不知道怎么实现

printf("%-30s, %s\r\n", "字符串", "2009-7-8");
printf("%-30s, %s\r\n", "字符串字符串字符串字符串", "2009-7-8");
printf("%-30s, %s\r\n", "字符串字符串", "2009-7-8");
printf("%-30s, %s\r\n", "字符串字符串字符串", "2009-7-8");
printf("%-30s, %s\r\n", "字符串字符串", "2009-7-8");
