private: System::Void listBox1_SelectedIndexChanged(System::Object^
sender, System::EventArgs^ e)
{
if (listBox1->SelectedIndex == 0)
{
textBox1->Text = "C++ Course is a course about c++!:D";
}
}
What’s will happen now?
What will happen when selecting another option after selecting C++?

ListBox - Coding
• It’s a runtime error if selecting nothing and then pressing
button2. Otherwise it works properly.
private: System::Void button2_Click(System::Object^ sender,
System::EventArgs^ e)
{
textBox1->Text =listBox1->SelectedItem->ToString();
}

CheckBox

28.
CheckBox
• CheckBoxes
– Set of non-connected controls
– Can choose one or more “checkBox”

29.
CheckBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + checkBox1->Text );
}
}
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + “English” );
}
}
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose English” );
}
}

CheckedListBox
• Hierarchy …
– System::Object
System::MarshalByRefObject
System.ComponentModel::Component
System.Windows.Forms::Control
System.Windows.Forms::ListControl
System.Windows.Forms::ListBox
System.Windows.Forms::CheckedListBox

41.
CheckedListBox
• Let’s have the following code …
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
if (checkedListBox1->SelectedIndex == 1 )
{
textBox1->Text = "WOOOW";
}
}
sender,

42.
Why?!

43.
CheckedListBox
• The same story goes with this:
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->SelectedItem == "French" )
{
textBox1->Text = "WOOOW";
}
}

44.
CheckedListBox
• So, we do this:
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->GetItemChecked(1) == true)
{
textBox1->Text = "WoW ";
}
}

45.
CheckedListBox
• Now, let’s see this:
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
checkedListBox1->Items->Add("Spanish");
}
sender,

46.
CheckedListBox
• And ofcourse, we can do this!
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
checkedListBox1->Items->Add(textBox1->Text);
}
sender,

47.
CheckedListBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->Items[0]->ToString() == "English")
{
textBox1->Text = "WoW ";
}
}

}

• So, how to break the restriction and select more than one

There’s sth called the “GroupBox” from “Containers” section.
