Thank you,
I am getting Debug Assertion in afxwin1.ini file.
I told that we have to create dlg instance globally because,when i create it inside the initinstance then dialog will be disappeared when the it is out of the scope,so I wanted it as a global one.

The file is over 1100 lines long. Which one?

Make it a member of your CWinApp-derived class instead.

So are you directly or indirectly calling AfxGetResourceHandle()?

No, I am not calling that function directly.
But global declaration where I am doing Is it correct?
After the App instance creation,I am creating Dlg instance.

I also asked about an indirect call. When the assertion fires, check the call stack.

Not in my opinion. Until you actually solve the problem, you'll not know for sure if it's correct or not.

Hi,
In my project i want to disable and enable Main Menu at run time using mfc .
I had try to run the following code, but don't send error occurred
CMenu* mmenu = GetMenu();
CMenu* submenu = mmenu->GetSubMenu(0);
submenu->EnableMenuItem(ID_FILE_NEW,MF_DISABLED | MF_GRAYED);
Please help me How to Disable/Enable Main Menu using View class
|
|
|
|
|
I don't think we can work on Menus using View object. try to get the MainWindow handle and use that handle for obtaining menus.
CWnd* wnd=AfxGetMainWnd();
CMenu* mmenu = wnd->GetMenu();
CMenu* submenu = mmenu->GetSubMenu(0);
submenu->EnableMenuItem(ID_FILE_NEW,MF_DISABLED | MF_GRAYED);
Try this and i hope this will work fine.

You can use Web Browser Control-CWebBrowser2 / CHtmlView
Somethings seem HARD to do, until we know how to do them.

Try using Web Browser control.

What do you mean by "use?" If you simply want to open a URL in the default browser, just use ShellExecute(). Otherwise, see the other suggestions.

how to input strings in new lines in edit box in MFC??????????????
|
|
|
|

Use "\r\n" to add a new line.
|
|
|
|
|
Also, make sure the control has the ES_MULTILINE style.

hi friend!
To add CDAORecordset class, create a new class from class wizard.
Type the Class name in the Name dialog box (e.g. CCEmp_Recset) and select the Base class as CDAORecordset.
Open the Emp_Dlg header file and add the following codings:
class CEmp_Recset;
with in the CEmp_Dlg class add the pointer variable
CEmp_Recset *m_set;
Add the member function in as
void Emp_Getset( ) for Receiving data from the table and transferred to dialog box.
void Emp_Setget( ) for transferring the data from the Dialog to table.
type the following coding on OnInitDialog( ) Function:
m_set = new CEmp_Recset();
m_set->Open();
Emp_Getset();
Type the following coding with in the function
void CEmp_Dlg::Emp_Getset()
{
m_ac_no = m_set->m_ac_no;
m_bank_name = m_set->m_bank_name;
m_bank_code = m_set->m_bank_code;
m_micr_no = m_set->m_micr_no;
m_remark = m_set->m_remark;
UpdateData(FALSE);
}
void CEmp_Dlg::EmpSetget()
{
UpdateData(TRUE);
m_set->m_ac_no = m_ac_no;
m_set->m_bank_name = m_bank_name;
m_set->m_bank_code = m_bank_code;
m_set->m_micr_no = m_micr_no;
m_set->m_remark = m_remark;
}
void CEmp_Det_Dlg::OnClickBtnMfisrt()
{
// TODO: Add your control notification handler code here
mset->MoveFirst();
Emp_Getset();
}
void CEmp_Det_Dlg::OnClickBtnMnext()
{
// TODO: Add your control notification handler code here
if(mset->IsEOF())
{
MessageBox("Reached at EOF()");
}
else
{
mset->MoveNext();
Emp_Getset();
}
}
void CEmp_Det_Dlg::OnClickBtnMprev()
{
// TODO: Add your control notification handler code here
if(mset->IsBOF())
{
MessageBox("Reached at BOF()");
}
else
{
mset->MovePrevious();
Emp_Getset();
}
}
void CEmp_Det_Dlg::OnClickBtnMlast()
{
// TODO: Add your control notification handler code here
mset->MoveLast();
Emp_Getset();
}
