From the MSDN:
"LBS_MULTICOLUMN
Specifies amulti columnn list box that is scrolled horizontally. The LB_SETCOLUMNWIDTH message sets the width of the columns".

You can use region. There are functions like Create CreateEllipticRgn , CreatePolygonRgn etc. After creatin region u can paint that using FillRgn.

In Gdiplus also there is class named Region.

If u can Dream... U can do it

You need to fill a shape that is a combination of the standard shapes, like ellipse, circle, etc. Am I right?

If so its better you use CRgn. You can create and combine different shapes to get what you needed. And after that you can use FillRgn function.

Hi
In my VC++ (VC 8) programme, it was an Server - Client Programme.
In client programme first module was an Authetication ,in that when the client was entering , they must give User-id and Password.,here I want to disable all the Hot Key functions(eg : Alt+Tab, Alt+Ctl+Del…… all function keys).
And after entering I want to enable the key function.

you can disable ALT+ TAB using ::RegisterHotKey(m_hWnd,010,MOD_ALT ,VK_TAB);
but i think disabling alt+ctrl+del is difficult..

Help me over the conceptual hump of complex activeX controls...

charlieg8-Aug-07 18:35

I don't want code, just big picture. I've got a handle on the standard activeX control concept, but I think it has corrupted my thinking. Suppose I have an activeX control. I want to create an activeX control that wraps and manages a set of these other controls. These internal controls will interact with each other.

I've been through many, many web locations, and I believe MS has provided all of the technical bits and pieces, but nothing in a coherent manner. Can anyone just point me in the right direction?

thx

Well, I blundered across an article that showed me how to put a frigging dialog inside of an activeX "control". At first, this made my mind go WTF | :WTF:

but the simplicity and elegance of how all of the code just plays is breathtaking.

Hi all. Is there some API or standard function to call to retrive the current name of the program running? Something like GetCurrentProcessId(), maybe something like GetCurrentProgramName() or something of the sort. Google and Yahoo dont seem to help and i dont know where to begin this sort of search. Any suggestions? Thanx in advance.

Change Window Color

Isn't there an easy way, e.g. a CWnd base member function, that can be used to change a window's foreground or background color? I have two cases; in one I would like to change the background color of an edit control, in another I would like to change the color of a button. From what I have seen so far it seems like I have to create new classes derived from, in this case, the edit and button classes so that they can handle a WM_ERASE and do the necessary painting. I must not understand something because this seems way more complicated than it would seem and I don't want to head down the wrong path.

Thanks,

Wayne King

Edit control, easy. Button control, you're on your own Smile | :)

For edit controls, you can add a handler (in the parent dialog/window) for the WM_CTLCOLOR message.
In response to that message, return a handle to a brush that the system will use to paint the background.

Here's an example that sets all edit controls in a dialog to green text on red background:

// RedBrush is a CBrush member of CMyDialog
RedBrush.CreateSolidBrush(RGB(0xFF,0x00,0x00));
...
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
    ON_WM_CTLCOLOR()
END_MESSAGE_MAP()
...
HBRUSH CMyDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    HBRUSH hbr = CMyDialog::OnCtlColor(pDC, pWnd, nCtlColor);

    if (nCtlColor == CTLCOLOR_EDIT)
    {
        pDC->SetTextColor(RGB(0x00,0xFF,0x00));
        pDC->SetBkColor(RGB(0xFF,0x00,0x00));

        hbr = RedBrush;
    }
   
    return hbr;
}

So that would set ALL edit controls in CMyDialog to those colors? How can I set just one control; say one with an ID of IDC_ANAOFFSET?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
