Math Output in DialogBased Program With MSVC++

[cyrus]

Hi friends:
I know this question might seem very simple but I need it urgently for my homework.

"Imagine I want to write a dialogbased program.It takes two integers (m_a and m_b) from user and shows the sum of them as result.It contains three edit boxes and a button control to exe the sum process.I use the following command:

void CMATHDlg::OnSum()
{
m_sum=m_a+m_b;
MessageBox(m_sum);
UpdateData(TRUE);
}


But after running, the sum result does not appear in the related editbox.And also it gives me error for type conversion.

WHAT COMMAND SHOULD I USE INSTEAD OF MessageBox?

I also will be thankful if you could introduce me a book for mathematical aspects of vcpp.

Thank you so much

Let me see now:

Do you wish to show result in editbox or in a message box?

Hi:

Of course I think showing the result in editbox will be more suitable but would you please tell me about both (showing in messagebox or editbox)

Thank you

If you want to display it into MessageBox,use method show:


MessageBox::Show(String^ text,String^Caption,MessageBoxbuttons,MessageBoxIc on);

e.g:

MessageBox::Show(result,"Result is",MessageBoxButtons::OK,MessageBoxIcon::Informat ion)

for TextBox,see Text property..

Also you will need to convert from int to String^

Thank you so much Savage
Would you please tell me about the showing in editbox too.I check "Want return" in style tab but should I add a function like EN_CHANGE OR EN_UPDATE?

Thank you again

I know you might be busy but please take a look at this example in :

It's not my main project I only created a simple example to learn the way math result can be shown in edit box.

Thank you

You are usimg VC 6,right?

I'm using Microsoft Vc express 2005,so I have some problems viewing your project.

Sorry,but I think that there is no editbox in M$ VC but there is textbox.They are same,I think.If they are same check for Text methode..
