Hi,
I want to display a Modaless Dialog box instead of Modal dialog box in mfc application.So,I called Create function instead of DoModal() inside the InitInstance() but I am getting Debug Assertion Failed error.
CDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.Create(IDD_DIALOG1);
if(nResponse)
dlg.ShowWindow(SW_SHOW);
else
MessageBox(NULL,_T("Error"),_T("Error"),MB_OK);
I dont know where made the mistake???

While creating dialog box pass the second parameter as NULL. After successful creation of dialog you have to assign the address of the dialog to the m_pMainWnd.
int nResponse = dlg.Create(IDD_DIALOG1, NULL);
if(nResponse)
{
m_pMainWnd = &dlg;
m_pMainWnd->ShowWindow(SW_SHOW);
}
else
{}
I think this will solve your problem.

Thank you,
I have to globally define the dlg instance,
CMfc_Modaless_vc6Dlg dlg;
CWnd* m_pMainWnd = &dlg;
while I do this after the application instance creation it is giving the same Debug Assertion Failed problem.I cannot declare the Dlg locally,so what i can do for this?

You should not have to do this.

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.

Use "\r\n" to add a new line.

Also, make sure the control has the ES_MULTILINE style.
