Hello dope community, I did search a lot about this but found nothing
so simply I do have 1 textbox, 1 label called "Invalid", 1 button and finally a text file
the text file has numbers in lines or more likely a zip codes written by that way:
"10000
23251
30021
51931
and so on..."
textbox = type the zip code number
button = to search if the number which i did type in the textbox is inside the text file or not
if yes then label1.text = "Valid"
and that's pretty much all of it
I tried the following but I know it's totally wrong + it doesn't work + it will talk so long time to type each and every single number in it
Thank you so much in advance
What I have tried:
nothing so far, I've tried this:
If value1 = 10000 or 23251 or 30021 or 51931 Then
Label1.Text = "VALID"
End If
