DialogResult Problem on FormClosing Event

Question

Hi there I'm having a strange problem that have never had before, Please see if you can help me figure it out.

No matter what button I press, I still get the "Did not work!" MessageBox.
Here's my code for the FormClosing Event:

System::Windows::Forms::DialogResult^ Confirm = MessageBox::Show("Would you like to save before you exit?\n"

, "Confirm Exit", MessageBoxButtons::YesNoCancel, MessageBoxIcon::Question);

if (Confirm == System::Windows::Forms::DialogResult::Yes)

{

MessageBox::Show("Saving... " + Confirm);

}

else if (Confirm == System::Windows::Forms::DialogResult::No)

{

MessageBox::Show("Closing... " + Confirm);

// close the form without saving

Application::Exit();

}

else if (Confirm == System::Windows::Forms::DialogResult::Cancel)

{

MessageBox::Show("Returned! " + Confirm);

// abort form closing and return to the application

e->Cancel = true;

}

else

MessageBox::Show("Did not work!");


I have also tried this:

e->Cancel = false;

System::Windows::Forms::DialogResult^ Confirm = MessageBox::Show(

String::Concat("Would you like to save before you exit?\n", "Confirm Exit",MessageBoxButtons::YesNoCancel,

MessageBoxIcon::Question,MessageBoxDefaultButton::Button1,MessageBoxOptions::DefaultDesktopOnly, false);

if (Confirm == System::Windows::Forms::DialogResult::Yes)

{

MessageBox::Show("Saving...");

}

else if (Confirm == System::Windows::Forms::DialogResult::No)

{

MessageBox::Show("Closing...");

// close the form without saving

Application::Exit();

}

else

{

MessageBox::Show("Did not work!");

// abort form closing and return to the application

e->Cancel = true;

}


I don't know what else to try!, Please help me find the problem.
Thanx.

Answer 1

Change the line

System::Windows::Forms::DialogResult^ Confirm = MessageBox::Show("Would you like to save before you exit?\n", "Confirm Exit", MessageBoxButtons::YesNoCancel, MessageBoxIcon::Question);

To

System::Windows::Forms::DialogResult Confirm = MessageBox::Show("Would you like to save before you exit?\n", "Confirm Exit", MessageBoxButtons::YesNoCancel, MessageBoxIcon::Question);

Note the removal of the ^

You'll also have to make some changes to the subsequent MessageBox::Show calls as they don't like 'Confirm' being added to a string (try Confirm.ToString() perhaps)

 Damn! I can't believe its such a stupid error, I did'nt pick that up.

Thanx for the quick reply.

I have a problem with this line:

else if (Confirm == System::Windows::Forms::DialogResult::No)

{

MessageBox::Show("Closing... " + Confirm.ToString() );

// close the form without saving

Application::Exit();

It shows the MessageBox again when I click No, then it closes the application.

Thank you.

Answer 3

That's because another event is trying to close the form and is therefore correct behaviour.

Either:

• filter the calls to FormClosing by the FormClosingEventArgs::CloseReason
• or call Environment.Exit(-1); //-1 refers to the process exit code

Answer 4

Damn! that was a fast reply!
Thanx.

I also found another solution, Using this:

e->Cancel = false;

That seems to work.

I think the flu that I have is affecting my brain a bit! lol.
