CSplitterWnd questions,

When my program starts, only one view of the four splitter window shows.  I 
have to manually drag the bars to induce the other 3.  My question is: how 
do I readjust the size of each splitter window in code?  Also, what method 
do I use to get a HWND (or CWnd) to each subdivided window?

The CMainFrame parent window resizes the splitter in its WM_SIZE message 
handler.  I suggest you add a WM_SIZE handler and do something like this:

void CMainFrame::OnSize(UINT nType, int cx, int cy)
CFrameWnd::OnSize(nType, cx, cy);
if (m_wndSplitter.GetSafeHwnd())
{ int cxCur0, cxCur1, cxMin0, cxMin1;
   m_wndSplitter.GetColumnInfo(0, cxCur0, cxMin0);
   m_wndSplitter.GetColumnInfo(1, cxCur1, cxMin1);
   cxCur0 = ... adjust sizes as desired
   cxCur1 =
   m_wndSplitter.SetColumnInfo(0, cxCur0, cxMin0);
   m_wndSplitter.SetColumnInfo(1, cxCur1, cxMin1);

This can not only set the sizes at startup, you can use this to maintain 
the relative pane sizes as the window is resized.

You can get a CWnd* for any splitter child with m_wndSplitter.GetPane().

Frx question
Having a problem trying to do a calc column. Is it possible to divide a colume by the base period number. For intance if this is August, i'd want the entire column divided by the number 8. What I've done in the past (to create averages) is create an excel file with the number 1-12 on A though L, then access the worksheet with a column period offset (CPO) setup.

Excel Conditional Formatting Question
I am trying to create a spreadsheet to track suspense dates for projects and I am having difficulty trying to use conditional formatting in order to complete my project. 1.

Questions for help
According to documentation, for a CMyDialog : public CDialog, CMyDialog::OnInitDialog calls CDialog::OnInitDialog, and then CWnd::UpdateData() is called. From which function specifically is the CWnd::UpdateData() called? Is there any chance that I have to explicitly call UpdateData() in CMyDialog::OnInitDialog()? My other questions are about worker thread: Worker thread lacks a message pump. If adding something like, PeekMessage() inside such thread, does this make worker thread become an UI thread? Is UI thread a general term on Win32 programming, or it just related to MFC programming? ...

Unicode Question
Is a Unicode character always represented as a single 16-bit integer for every language besides the oriental languages? No. Read about surrogates. A number of other languages, particularly some of the more obscure scripts (including several dead scripts which scholars in those areas use to communicate their findings, such as Cuneiform), are in the surrogate range. You should probably get the Unicode 5.0 standard which is now available. Apparently it incorporates a lot of material previously scattered throughout the Unicode Consortium's site. There's a link to it from my Web s...

Conditional Formatting Question #5
Using Excel 2000, can I conditionally format a row to change background color when the first column meets the condition of the current date (within a 7 day range) I would like the color to default to white unless the condition is met, then the row be highlighted to show the current weeks row. Hope I explained this well enough. Mark Strohmeyer Seems possible, but I think you will have to provide an example. I'm confused by what "within a 7 day range" means. Do you mean, 'if the date in column A is between today and 7 days from now'? If I'm guessing correctly, highl...

Form design question 10-24-07
Suppose we have a customer form where the first field on the form is Customer Name. (There's a Customer Code as well which is the actual key of the file, but that is hidden from the user.) The Customer Name field is a combo box that the user can use to jump to a specific customer. The only catch is that, on the rare occasion when the user needs to modify the customer name, we need to alert Access that their typing is meant to change the customer name, not jump to another customer. So we've added a button for "Edit customer name". We've used the button for editing t...

formula question #19
Need help on 2 formulas. here the work sheet cell A1 will have input either letter DO then a number (i.e. D102) or just the number (i.e. 134) cell A2 & A3 will input only numbers. (i.e. 9) 1st formula Cells A4 will add A2 + A3 only when cell A1 starts with the letter D (ie D102) Cell A5 will add cells A2+A3 only when cell A1 does not start with the letter D.

CBitmap and CDC question
Hi, How do you create and dispose of a CBitmap correctly? When destroying CDC objects do I need to call DeleteDC, because when resizing a CDC I select its old object and call deleteDC. Then I use createCompatibleBitmap and CreateCompatibleDC to reuse the object. Is this correct? Thanks. I'd be surprised if you ever needed to call DeleteDC under any conditions, since it is rare to ever need to write that call at all. It is equally rare to ever write GetDC calls. Typically, a DC does not exist longer than a single funciton invocation, and therefore you are more likely to write CClientDC...

Alias question

ORDER BY tblEmp.LName & ", " & tblEmp.FName , but the SQL Help says that ORDER BY can be followed by the name of any field, and the alias following the 'AS' should have assigned 'FullName' a...
