Using the InputBox Function

Note: The InputBox function's syntax also includes optional XPos and YPos arguments for

specifying the dialog box's horizontal and vertical positions, respectively. If both arguments are

omitted, the dialog box appears centered on the screen.

Basic syntax

InputBox$($prompt$[,$ title$][,$ defaultResponse$])$

Example $1.$

strSales $=$

InputBox$("$Enter a sales amount. Click Cancel to end.",

"Sales Entry", $"0\mathrm{.}0")$

Displays the input dialog box shown in Figure B$-5.$ When the user closes the dialog box, the

assignment statement assigns the function's return value to the strSales variable.

Example $2$

strCity $=$ InputBox$("$City name:", "City"$)$

Displays an input dialog box that shows "City name:" as the prompt, "City" in the title bar, and

an empty input area. When the user closes the dialog box, the assignment statement assigns

the function's return value to the strCity variable.

Example $3$

Const strPROMPT As String $=$ "Enter the discount rate:"

Const strTITLE As String $=$ "Discount Rate"

strRate $=$ InputBox$($strPROMPT$,$ strTITLE, $"\mathrm{.}00")$

Displays an input dialog box that shows the contents of the strPROMPT constant as the prompt,

the contents of the strTITLE constant in the title bar, and $\mathrm{.}00$ in the input area. When the

user closes the dialog box, the assignment statement assigns the function's return value to the

strRate variable.

Example $4$

Integer.TryParse$($InputBox$("$How old are you?",

"Discount Verification"$),$ intAge$)$

Displays an input dialog box that shows "How old are you?" as the prompt, "Discount Verification"

in the title bar, and an empty input area. When the user closes the dialog box, the TryParse

method converts the function's return value from String to Integer and then stores the result in

the intAge variable.

Can you describe another situation when the InputBox Function could be used? Why would

the function be helpful? What would it achieve? Create an example like the ones shown in

the figure above and include it with your response.
