hello all,
I need to create edit controls in the formview window that would accept numeric digits like 1.3 5.7 etc., .
but when I try building/executing the program, I cannot type in values like 1.3 etc., it gets rounded to 1 ; and 5.7 gets rounded to 6.

I use VC++6.0 . and i have created edit memeber variables using classwizard of type double and in SetWindow, I pass as double.

Should I be using/including some other relevant class to be able to do this? Cant I do otherwise.

Any help appreciated.
Thanks.

How do you know that they are rounded? Did you trace through to the variables storing them?

After sucessful building of the program,
in the formview window that pops up, I tried entering 1.3 in the edit control box. but it immediately rounds to 1 by itself.

sorry if this doesnt answer your question...this is my first project in MFC.

I created a formview project but i did not encounter this problem. The only thing i notice is that if you set the Number property to true, it will not allow you to enter decimal point. Did you change any property values for the edit control?

nope. I dont have the number property enabled.
I can type in a decimal point followed by numbers. but once i finish typing, the values get rounded.
I have set the maximum and minimum to be 10 and -10 respectively.

Does the value you enter remain the same as 2.4 as such when you start entering values in the other edit boxes.?

Yes, try removing the minimum and maximum limit that you have set to see if it works.

hello,
since i wanted to limit the range between +10 and -10 ..i had the following code inside the member function for that edit box.

void CSample2View::OnKillfocusEditMirrOS() <br />
{<br />
	// TODO: Add your control notification handler code here<br />
	if (m_dMirrOS <= -10)<br />
		m_dMirrOS = -10;<br />
	else if (m_dMirrOS >= 10)<br />
		m_dMirrOS = 10;<br />
	else<br />
		m_dMirrOS = m_dMirrOS;<br />
<br />
	CString strMirrOS;<br />
	strMirrOS.Format(STR_FMT_FLT_D,m_dMirrOS);<br />
	m_editMirrOS.SetWindowText(strMirrOS);<br />
	<br />
}

where, STR_FMT_FLT_D is defined as _T("%d")
when i comment out the above code inside the killfocus...(),
I can enter values with decimal points. But I want to have a upper and lower limit for my control box so that weird values doesnt get entered for that particular control.

how do i do it?

Your problem is at

strMirrOS.Format(STR_FMT_FLT_D,m_dMirrOS);

Since STR_FMT_FLT is defined as _T("%d"), any decimal values you try format will be rounded. Change to _T("%f"). If you want to limit to 2 decimal places, you can write as _T("%.2f").

You can watch a directory with FindFirstChangeNotification() or ReadDirectoryChangesW()

hi,

Thanks guyz for your quick responses..Michael Dunn, Jubin Chawda and WhiteSky

From the link i get a clear idea..

But i want to run my program like background process.
On pressing Ctrl+Alt+Del my program wanted to be displayed in the Process Tab rather than in the Program Tab.
I'm trying to implement in VC++ with out MFC.
