MFC modal dialog prevent another modal dialog to continue after dialog closed
1
Created a simple mfc project, then create three dialog and add CDialog class.
TestA, TestB, TestC classes.
In the main frame dialog,
void CMFCApplication3Dlg::OnBnClickedButton1()
TestA *a = new TestA(CWnd::FromHandle(GetSafeHwnd()));
a->Create(TestA::IDD, CWnd::FromHandle(GetSafeHwnd()));
a->ShowWindow(SW_SHOW);
void CMFCApplication3Dlg::OnBnClickedButton2()
TestB b;
b.DoModal();
AfxMessageBox(L"B closed");
Class TestA has,
void TestA::OnBnClickedButton1()
TestC c;
c.DoModal();
AfxMessageBox(L"C closed");
The problem is occur when
- Open TestA
- Open TestB
- Open TestC
Now when i close TestB the AfxMessageBox(L"B closed"); is not run until i close TestC dialog.
Why is this happen?

Please provide a Minimal, Complete, and Verifiable example. It appears like you do not understand modal and modeless dialogs well enough to use them proficiently, and it is unclear from the question, what you are ultimately trying to accomplish.

probably becausec.DoModal();doesn't return until the TestC dialog is closed, so the program waits at that point

At least to me it is totally unclear what you mean with "Open TestA, Open TestB, Open Test C". TestB is opened as a modal dialog, so TestA should not see any "OnBnClickedButton1" and TestC should not open!?
