DIALOG BASED APPLICATION | CREATE DIALOG BASED APPLICATION WITH VARIOUS CONTROL USING VC++

OBJECTIVE:
To create a dialog based application with various control using VC++.
PROCEDURE:
1. Run the MFC AppWizard(exe) to generate dialog
2. In step1 dialog based application select the default settings and press OK button.
3. In resource view click on the dialog and select the IDD_DIALOG1
4. Design the dialog using the dialog editor
5. Use edit controls to get the name, age combo boxes for date for birth, edit box to read the parents name, monthly income, list box, to list the education
6. Right click on the monthly income select class wizard->member variables
7. In edit4 (monthly income) select the variable namaes m_sal and select the data type as int and click OK.
8. In date of birth using combo boxes for day ,month, year
9. Right click on the list box select properties and give the ID name as IDC_EDU
10. Radio button yes, no to check the transfer certificate availability
11. Radio button yes, no to check the birth certificate availability
12. One command button for selection and another to quit the project
13. In dialogdlg.h declare 2 variables
Public:
CString SelString1;
CListBox *m_fath_edu;
14. In the Dialog Dlg.cpp add the following code OnInit Dialog function
CListBox *PLB=(CListBox *)GetDlgItem(IDC_EDU);
PLB->InsertString(-1,"Graduate");
PLB->InsertString(-1,"Post Graduate");
PLB->InsertString(-1,"High School");
PLB->InsertString(-1,"Professional");
PLB->InsertString(-1,"Illiterate");
15. Using the class wizard map the object Id as IDC_EDU with the message LBN_selchange notification handler is created with this OnSelChangeEdu()
void CDialogDlg::OnSelchangeEdu()
{
// TODO: Add your control notification handler code here
int SelIndex1;
m_fath_edu=(CListBox*)GetDlgItem(IDC_EDU);
SelIndex1=m_fath_edu->GetCurSel();
m_fath_edu->GetText(SelIndex1,SelString1);
}
16. Using the class wizard map the object Id as IDC_BUTTON1 with the message BN_CLICKED a notification handler is created with this OnButton1()
void CDialogDlg::OnButton1()
{
// TODO: Add your control notification handler code here
UpdateData(true);
if((m_sal*12>10000)&&(SelString1!="Illiterate"))
MessageBox("Student Selected");
else
MessageBox("Student not selected");
}
17. Using the class wizard map the object Id as IDC_BUTTON1 with the message BN_ CLICKED a notification handleris created with the OnButton2()
void CDialogDlg::OnButton2()
{
PostQuitMessage(0);
}
18. Run and test the application
