How to avoid a Global Variable

[Madhu_Rani]

Hi, I have an SDI application and in view class, I call a dialog by using dlg.DoModal(); There is an EditBox in the dialog and I want to use the entered value in the view class. Now one way is that I declar a global variable and store the value in it. or declare a varibale in App class and use that variable. Is any other fine way to do the stuff and I may avoid variable at application level/global? THANKS

something like this ?

void CMyView::SomeFunc()
{
CMyDialog dlg;

if (dlg.DoModal() == IDOK)
{
m_myVar = dlg.m_editVar;
}
}

You can also pass the old value to its constructor as the initial value and make a "Get" method in the dialog class to return the new value.

void CMyView::SomeFunc() { CMyDialog dlg; if (dlg.DoModal() == IDOK) { m_myVar = dlg.m_editVar; } } This works fine for OK button but does not work for other buttons such as Connect having id IDCONNECT... any idea why? if (dlg.DoModal()==IDCONNECT) {// does not work }
