Thread: Test cases for Text Box, Drop Down Box and email ID

Can anybody tell me how to write testcases for Text Box, Combo box and Email ID(format is xyz @ abc.pq.re)?

This is an example of code for test cases of all characters in a string of a textbox or all numeric in textbox. I hope you find it helpful. It is written in visual basic .net
public sub testcase()
dim textcontent as string
textcontent =textbox1.text
' test if string is all characters
dim k as integher
k=len(textcontent)
dim i as integer
for i=0 to k
if isnumeric(indexof(textcontent,i)) then
msgbox(" please enter charachters only")
exit sub
end if
next
' test if string is all numeric
for i=0 to k
if not isnumeric(indexof(textcontent,i) then msgbox(" you should enter only numeric values")
exit sub
end if
next
end sub
