Looping Through String Using Excel VBA!

[Jdean]

Hello!


I hope someone can help me with this.

Assume:
String A contains "5, 45, 100, 113, 160"
String B contains "2, 4, 45, 160, 189"

If want to compare the two strings to check whether they have two integers in common, in this case it will be "45" and "160".
How I have approached my solution is to use the split function to split each string into 2 arrays. Then using two For-loops I compare each token of each string array to the tokens of the other array. Then using a counter if there is a match then I increment the counter. If the counter is >=2 then it means the two share at least two numbers.

This approach works fine except I will be doing this for two very large sets of strings and it is very time-consuming in execution. Is there a faster VBA method or data structure to use instead of breaking the two strings up into two arrays and creating two For-loops?

Any suggestions in VBA code would be appreciated.

Thanks!
Jdean
