InStr

[Chris Calzaretta]

Hello Everybody,
Question

instr function will give you the first instance of the finding
so EX:
so your string looks like

string1 = "testing>This is > just a test > testtesttest"
instr(string1,">")

so instr will give me a 8 as a return item
i need to get the last instance
Easy way to do this.

Thanks
Chris

Super easy!

Change "Instr" function to "InStrRev " function, which gets the
position, starting from the right side of the string.

Something like this

Untested
Len(mystring) - InStr(StrReverse(mystring), ">")

Chris,

When you want to use the Zero indexer ( I assume you don't want it however
to get the answers complete than there is instead of the InStringRev as well
the instruction). Don't expect any advantage from that, than that you are
using the Zero as starting indexer instead of that you get back when it is
on the first position a 1.

dim pos as integer = String1.lastindexof(">")
it gives a -1 when that is not in it.

I hope this helps,

Cor

Finally someone that uses the right .Net way instead of the
old-fashoned-VB6-retro-compatibility functions, that aren't OOP and aren't
so fast as native ones.

I did nowhere write it is "better", when you see Hefried samples, than he is forever using Mid, Right, Left in that case I would find it very incosequent to use indexof.

I don't care about bad-coded-samples ;)
