Nevermind.. I see that the thread can exit with a different value than the dialog.

MFC Controls in CDHtmlDialog

I was wonderng, is there any way to use MFC Controls in a CDHtmlDialog?

Currently, I have a rather attractive looking GUI which is a modified off of a design I got from am "open source web design" website, which I have modded up with some javascript/etc for the purposes of my program.

However, I would like to have a list control in the lower portion of my screen.

a screenshot can be found --> http://24.150.11.236/gui1.png

what I would like, is to have a MFC Control in where I have ---List Control would go here---

(the design I modified to use http://www.oswd.org/viewdesign.phtml?id=559&referer=%2Fbrowse.phtml%3Fcategory%3Dclean%26offset%3D35%26sort%3Dposted_date%26min_rating%3D3 )

Currently, the only thing I can think of doing, is making a CDHTMLView type class, and using splitters and having the top be the HTML, with just a straight up MFC List control in the bottom half, but I'd much rather find a way to imbed it into the page itself.

any ideas?

create an ActiveX control that contains a list ctrl. embed that on your page.

I'll have to double-check this when i get home, but doesn't CDHtmlDialog use both an old-style dialog template and a HTML dialog template? What happens when you put the list control on the normal template?

I got thinking of that after I posted this so I tried it, and the control displays ontop of the HTML, which gives me the desired effect I want.

Now just the matter of being able to move/re-size it as needed to keep it in position.

Remove button from system tray

Hi!

I try to place or remove my MFC program's button in the system tray by using:

ModifyStyleEx(WS_EX_APPWINDOW, WS_EX_TOOLWINDOW);

or vice versa. When I place this statement in OnInitDialog, everything works fine. But when I place it somewhere else so that I can do the change "on runtime", nothing happens. Well, the Icon on the button in the system tray does vanish / reappear depending on the setting, and GetExStyle() shows that the settings have changed - but that's it. Any ideas, or do I have to give it up?

Thanks,

Martin

You mean the taskbar icon? Smile | :)

Check out Nish's article "Some handy dialog box tricks" (or something like that Smile | :)

)
I don't know where to find it and have no time to get the URL for ya, but search here on CP or perhaps Nish himself can tell ya! Smile | :)

No - I meant the icon in the button on the taskbar;)

I checked Nish's article, but even though it's pretty good it didn't solve my problem, as he did the removing of the button in OnInitDialog...

Adding a bitmap in the background of a richedit

Hi,

Is there a way to draw a bitmap in the background of a richedit?

I tried to override WM_ERASEBACKGROUND, but it does nothing.

I read that we can put the WS_EX_TRANSPARENT style and draw on the main window, but I want to do all the drawing in my derived CRichEditCtrl.

How can I do?
thanks,
John

In fact I added the WS_EX_TRANSPARENT style to the richedit, and since the background is now transparent, I override WM_ERASEBKGD message to draw my bitmap.

The only problem I have is a flickering problem while sizing the window, because since the richedit is transparent, before I draw its background, the main dialog repaints itself under it.

Does anyone know how I can avoid it?

afxDump: preventing 'dropped' output

moredip9-Apr-02 6:54

9-Apr-02 6:54

Howdy all,

I've got a bit of a problem with TRACE(), mainly that I'm using it too fast for the buffer to be written to the debug output, leading to a few lines of output being dropped. I know that trace uses afxDump, which is a CDumpContext.

Is there anyway to assure that all TRACE output gets to the debug window, even at the cost of performance? The only thing I can think of is putting an afxDump.Flush(); before all TRACE statements. Which is a bit of an ugly solution.

I guess making a class derived from CDumpContext, and having it's operator<<() not return until the buffer is written out.

Anyone got any better sugestions?

TIA,

Pete

Can you just use OutputDebugString(...) directly? I think you might still see "dropped" output if you hit it hard enough, but that would be because of Visual Studio, not OutputDebugString(...).

Peace!

moredip9-Apr-02 8:40

Would that actually make much difference? From my reading of MSDN: "Under the Windows environment, the output from the predefined afxDump object, conceptually similar to the cerr stream, is routed to the debugger via the Windows function OutputDebugString". I guess you're saying that CDumpContext is internally buffering the output, and that's buffer overflowing is the problem.

I think it's more likely that the stuff is being dropped after OutputDebugString(), on it's way to VS. I seem to remember someone mentioning this on CP a while back, when I first had the problem. I guess the Interprocess Communication (or whatever) isn't fast enough.

Thanks anyway,

Pete

Setting the min size a floating dock bar can be sized to?

Roger Allen9-Apr-02 6:45

Roger Allen

9-Apr-02 6:45

I have a floating window that is ultimately derived from CControlBar. I have been trying to find a way to limit the minimum size that the user can re-size the window to using the mouse.

I have tried WM_GETMINMAXINFO, WM_SIZING, WM_WINDOWPOSCHANING etc. I have even tried intercept the WM_NCLBUTTONDOWN where the sizing operation should be started, but thats not catchable for some reason.

Does anybody know of any way to set the minimum size a dock window such of this can be re-sized down to? There is obviously some kind of default used by the system as it does have a minimum size, but I need to change what that minimum is.

Cheers, for any ideas or even better, solutions!

RegisterHotKey()

9-Apr-02 6:23

When you register a HotKey using RegisterHotKey API function in a dialog based MFC app,
where do you capture it?
I tried CDialog::PreTranslateMessage.
Doesn't seem to be working

I used something like

if (pMsg->message == WM_HOTKEY)
{
    switch (pMsg->wParam - 40000)
    {
    case 1: //menu display key
        {
            CRect loRect;
            this->GetWindowRect(&loRect);
            CPoint loPoint= loRect.CenterPoint();
            OnRButtonDown(0, loPoint);
            break;
        }
    }
}
return CDialog::PreTranslateMessage(pMsg);

from VC++6 to C++.net

9-Apr-02 6:11

In VC++ 6 there was a menu command Add to Project >> components (or some thing like that) which was used to insert registered ActiveX controls or Visual Studio components.
We used the Visual Studio Components (or was it Visual C++ components) to add references to MAPI, MCI etc. libraries. In VC.net this command is gone!
How can we make references to MCI, MAPI like stuff now.
I mean simply using #include <mmsystem.h> doesn't work Frown | :(

Please help

To add libraries to use in VC++.NET; in the solution explorer windows right click on the name of your project (under solution and before the file listing), then select properties. Then look under linker / input.

Seem like everything is a property in the new .NET Studio.
