Thanks to everyone!
I knew it would be simple, I just couldn't find it. I opted for a quick and "dirty" approach of keeping track of it with an array of ints (yuk). I'll switch to GetItemCount now.

You can retrive it from the associated header control.
e.g.
CListCtrl m_lstItems;
int nNumCols = m_lstItems.GetHeaderCtrl()->GetItemCount();

All I need are two buttons that have an up arrow and a down arrow. I looked at CBitmapButton class but I dont need it to look different when pressed etc. If I could just draw on a regular button - thats all I need.
So I am looking at the spinbutton ctrl. I dont need the autobuddy stuff, just access to a function that fires if I press the up arrrow, and a different one for the down arrow of the spinbutton ctrl.
If neither of these is suitable, I can just write the text "Up" and "down" on my regular old buttons ,,,,it just wont look so cool........
Suggestions?
Appreciate your help,

Well, the spin button control sends a WM_VSCROLL message when you click on the arrows (if it's vertically aligned). Also the MSDN says it sends a UDN_DELTAPOS message, but I've never used that before. So, hook up a handler for WM_VSCROLLL and look for SB_LINEUP and SB_LINEDOWN or SB_PAGEUP and SB_PAGEDOWN (can't remember which ones are sent by the spin button).

Hi all,
This is just a shot in the dark but is there someone out there who has used Crystal Reports 9 successfully with unmanaged visual c++ code, preferably in a MFC application? The examples on crystal decisions website are too terse to understand and there seems to be no sample files that don't need managed code.
Cheers,
Clint

I use a CEdit Control among other controls like a CListBox and a CCombox (but in DropDownList mode) in a CView window. Everything goes well except that when i click on the CEdit Control I don't succeed in obtaining the focus on it. I succeed in obtaining it only with a double click, and there are some visual artefacts when I click on the other controls (the appearance of the Edit stays selected). And if I active an other application or if I open a Dialog Box when the document frame is activated again, the simple click is working quite well. And when it begins to work it work until i exit from the application. Is somebody has an idea about that?

What gains focus if not the edit control? Check if the view is set to focus another object upon single mouseclick.

It seems that the focus stays on the control which had the focus before the click. Another strange thing about the CEdit Control if I strike TAB we do not go to the next control and we have a bip.
I am perfectly sure that the focus is not set to another object on sigle mouseclick

Hi everybody
I have to show a list of values in a list in different columns.
There is a simple way to show them right aligned?
Ex
YEAR PRICE BOYS GIRLS E.T.
1992/1993 200 5 4 7
1993/1994 3.000 27 45 126
Thanks in advance.

Sorry the example looked good in the editor but not in the final message

If you want the columns right aligned, specify LVCFMT_RIGHT for the nFormat parameter of the InsertColumn function. This will work nicely for all columns except the first one. For some reason, you can't right align the first column I don't think.
YourListControl.InsertColumn( 0, _T("Column0"), LVCFMT_RIGHT, 100 );

You can, but you have to set the style to right align after you have created the column.

I'm trying to make a Winamp plugin (Win32 DLL) and a text-only one will compile just fine. Whenever I add any resource script to it, however, I get this error:

I'm trying to find out if there's a way to leverage the "Searching" progress indicator in XP. When you search for files in Exporer displayed the Luna interface, you get a little wrap-around progress indicator with 3 gradient filled boxes. It basically uses a WM_TIMER message to update the box positions.
Spy++ tells me that this the window class is SA_Progress, but a Google search gives me only 1 newsgroup comment. I know it's trivial to implement, but I'd like to conform to the active theme colors and shapes, and the documentation for GetThemeColor isn't exactly definitive (or existant). Any suggestions? Thanks.

Check out CListCtrl::GetTopIndex and CListCtrl::GetCountPerPage. You should be able to calculate the last visible item this way. Cheers.

Hi,
I'm trying to turn a bitmap on and off (if it were a CWnd, I would use CWnd::ShowWindow(SH_HIDE) ) How can I do this?
Basically, here is what I will have:
I will have "layers" of bitmaps in one rectangular area. I am a little familiar with device contexts and will try to associate each layer with it's own device context.
When I want to Show/Hide a layer, I will operate on that specific device context.
Each layer will have a unique color used -- there is only one color used in drawing on that layer.
Are there any suggestions on how I can programmatically turn on/off a specific layer?
Thank you very much!

If you have no more than 8 layers, just use an 8 bit deep
bitmap-- treat it as a paletted image. Generate the palette
on the fly depending on the colors of the layers, their
transparency, order, etc. Then blit to the display using the
generated palette. If you have more than 8 layers, then
you can do the same but your original bitmap will not be
compatible with gdi as is-- use it to construct a final
image and blit that to the display.

This is in the lines of what I was looking for. I'm adapting the Oscilloscope project in CP's
"http://www.codeproject.com/miscctrl/oscope.asp" by Mark C. Malburg
and he uses bit blit-ing.
I will be putting 5 (maybe 8 max) plots on the same grid. If the user wants to turn off a plot(s) then that is when I want to do my business.
Any more suggestions/help? Thanks all!
Johnny

Make sure when drawing into the layered bitmap,
to use the R2_MERGEPEN raster op so that when
drawing with a pen designed for one layer you
aren't obliterating the others.
