Normal single-line InputBox
Multi-line InputBox
Demo app
Using the class
Just add a reference to InputBox.dll in your project. The class is
part of the namespace CodeProject.WinForms
. So you might want to add
using CodeProject.WinForms
on top of your source files. Of course that is if
you are using C#. For an MC++ app you need to put
using namespace
CodeProject.Winforms
on top of your source files.
InputBox Constructor
InputBox();
- This creates a normal InputBox with a single
Input Line
InputBox(bool);
- Depending on the bool
you pass, this
overload will create a multi-line InputBox if you pass true
and a single
line InputBox if you pass false
Example:-
InputBox m_ib = new InputBox();
InputBox m_multi_ib = new InputBox(true);
Show() - The key function
This has two overloads.
String* Show(String* prompt);<br>
String* Show(String* prompt, String* title);
prompt -
This is the prompt text that will appear in the
InputBox. It's a Label control and thus it will word wrap.
title
- This is the window title of the InputBox
Return Value
The String that was entered is returned, if the OK button was clicked. If the
Cancel button was clicked an empty string is returned.
Sample Code
InputBox m_ib = new InputBox(true);
this.textBox2.Text = m_ib.Show("Enter your address please.",
"Your address");
The class structure
