After getting the drives from GetLogicalDriveStrings, you need to use GetDriveType and test if the return value = DRIVE_CDROM.

Like it or not, I'm right.

linked Multi dialog based MFC app

Hello,

I have to develop a dialog based MFC app in which several dialogs are linked using next/previous buttons, like in all those install apps.
As i dont have much time to do this, and as i havent used C++ in 3 years, i was wondering if a framework, or even some sample source code for such an app existed somewhere.

Thank you for your time. Smile | :)

you want to look at CPropertySheet and CPropertyPage..
basicly you use the resource editor to create dialogs, but instead of creating dialogs you create Property Pages (set to child instead of popup).. you create these for each of the pages you need.

then to put it all together you do:

CPropertySheet MySheet("This is my installer");
CMyPage1 page1;
CMyPage2 page2;
...
CMyPageN pageN;

MySheet.AddPage(&page1);
MySheet.AddPage(&page2);
...
MySheet.AddPage(&pageN);

MySheet.SetWizardMode();
MySheet.m_psh.dwFlags |= PSH_NOAPPLYNOW; // disables the 'apply' button
// display the form and wait for the finish button
if (MySheet.DoModal() == ID_WIZFINISH)
{ AfxMessageBox("woop!"); }

the CMyPage1,2,3 are the classes you created from your dialogs(proppages)

in your first page you need

BOOL CMyPage1::OnSetActive() 
{
   CPropertySheet* psheet = (CPropertySheet*) GetParent();   
   psheet->SetWizardButtons(PSWIZB_NEXT); // only have a next button on first page
   return CPropertyPage::OnSetActive();
}

in your middle pages you need

BOOL CMyPage2::OnSetActive() 
{
	CPropertySheet* psheet = (CPropertySheet*) GetParent();   
	psheet->SetWizardButtons(PSWIZB_BACK | PSWIZB_NEXT); // have next and back on middle pages
	return CPropertyPage::OnSetActive();
}

in your last page you need

BOOL CMyPageN::OnSetActive() 
{
	CPropertySheet* psheet = (CPropertySheet*) GetParent();   
	psheet->SetWizardButtons(PSWIZB_BACK | PSWIZB_FINISH); // have back and finish on last page
	return CPropertyPage::OnSetActive();
}

theres enough code to get you started.. if you can't get there from this then you prolly need to read a book or somethin.. there are examples on this stuff in the articles on here..

As your already mentioned this does not work on Win2k and above.
But there are some hacks (i.e. hooks, what a nice play on words Wink | ;)

) here at codeproject.
Maybe someone knows a direct link, I don't find the article right now.

edit box - with popup

I'm trying to come up with a way to have a popup come up when my edit box receives focus.

I've tried the OnFocus, but there were problems with that.

What I want is a soft-keypad to come up so the user and input data.

Any ideas.

Thanks in advance.

Jim

Use some kind of static boolean flag variable in OnFocus handler and don't allow renentry into code which opens keypad.

I see that this is probably the only way with an edit box. But I think there will be a problem of the focus staying on the edit box and the dialog coming up when the window looses then recieves focus will the "cursor" is still in the box.

Is there a command to move the focus to another "safe" place?

Re: edit box - with popup

dazinith4-Jun-02 5:42

just set focus to another field when the dialog closes?

CEdit* pNextField = (CEdit*)GetDlgItem(IDC_ANOTHERITEM);
pNextField->SetFocus();

??

Well, if it's modal and invisible your UI will be effectively frozen. Why do you want to do this?

//This dialog box have the functions and the
//messages to be processed.
CClassDlg objDlg;

if (objDlg.DoModal() == IDOK)
return TRUE;
else
return FALSE;
//My function will return when all done.
}

In the properties of dialog change the 'visible' property to false.Then add the bool variable to your class.Lets name it m_bFirstShowWindow and in constructor make it true.Then overriden OnWindowPosChanging and put this code in it:

void CYourDlg::OnWindowPosChanging(WINDOWPOS* lpwndpos)
{
	CDialog::OnWindowPosChanging(lpwndpos);

	if(lpwndpos->flags&SWP_SHOWWINDOW)
	{
		if(m_bFirstShowWindow)
		{
			m_bFirstShowWindow=FALSE;            
			lpwndpos->flags&=~SWP_SHOWWINDOW;        
		}
    }
}
