HI
I need to check the substring in uppercase or lowercase in vb.net

e.g
THIS IS TESTING - No problem
this is testing - No problem
this IS TESTING - Problem (

here we found any uppercase need to convert to propercase.

Thanks

Not clear. How "THIS IS TESTING" is not a problem? Formalize the requirements, please. What substring?

Solution 1

~~You can make use of String.Compare with ignoreCase set to true.~~

You need to build in a parser that adheres to English grammar(assuming that's the only language you support) rules and then split string based on certain characters, for instance period (.) or a question mark and then change the case.

1. Extract first character and make it upper case.
2. Check for ., ?, ! etc. and next character after that(excluding space, if any) should be uppercase.
3. Are you dealing with abbreviation? If yes, have dictionary of predefined abbreviations and make sure they all are in uppercase.

Thanks for your response, Need to compare with a single string

E.g a = "THIS is testing"

here we need to change only "THIS" to propercase no need to check "is testing"...

Output : This is testing

No. You never explained your criteria. Please understand that giving example does not mean define.

That's often the case here, isn't it? I just extrapolated that example as much I felt like.

Right, unfortunately. I prefer not answering in such cases. It's like development a wrong reflex. And I think being a human should be a required prerequisite. :-)
