C / C++ / MFC

To write list control records into text file use structure you can write and read entire row of list control. it will be better to seek the file pointer while reading and writing

Put some traces inside your code, so you can know what is going wrong at some PC.

unsure if this may be a solution for you, but worth a look :) WINXP-SP3 - The specified program requires a newer version of Windows.[^] Looks like the root of the error is to do with how/when GetLastError. Hope this helps.

The code you wrote above must be written in class void CDataDialog::OnBnClickedOk() ?Cause I have declare this class in a different dialog. I'm sorry for asking again, I got a little bit confused.

roh = mgh obviously. Now you need to know the thickness of the air at any point on the planets surface and adjust for air pressure.

Is it a homework? What is your variant of the solution? What does not work in your solution?

Did you ever find an answer here? I have the same issue.

Please, see my reply to the same question in CG forum: [Handle WM_LBUTTONDBLCLK on CMainFrame](http://forums.codeguru.com/showthread.php?558843-Handle-WM\_LBUTTONDBLCLK-on-CMainFrame&p=2211363#post2211363)

I try everything you propose!!every answer is helpful as I trying something like this for the first time!!thank you for your proposes!! :)

Indeed. You simply needs to return HTCAPTION on the WM_NCHITTEST message. Which is OnNcHitTest in the MFC framework. Best Wishes, -David Delaune
