Multiple Views with Activex Controls

Hi,

I have to display a window with top pane displaying a richtext edit control and bottom one displaying msflexgrid.

I added two controls(rich text edit control and msflexigrid).
Created two views.
Added a variable(rich text) for the first view.
Added a variable(msflexigrid) for the second view.
In mainframe.cpp in oncreateclient
i created a static splitter and createdviews with the two views.

But none of the splitter window(view?) is displaying activex control.

What should i do.

Regards,

Take care of the z-order of the windows. The farther is "less" visible.

Thank you. It worked. But a small problem.
The top pane/view contains richtext edit control. on CSize of View function i added code to adjust richtext edit control position. This is working fine.

But the bottom pane/view contains msflexgrid. on CSize of View function i added code to adjust msflexigrid control position. This is not working i mean it is in the initial position of (0,0,0,0). What property of msflexigrid control should be set or is it the intended behaviour of msflexigrid control.

Regards

Try setting the AllowUserResizing property to flexResizeBoth.

Hi,

I don't now the number of columns in advance for a msflexigrid. How to compute the columns dynamically and pass to the function setcols.

GetCols() gives you the number of columns
SetCols() allows you to set the new number of columns
SetColPosition() is used to change the position of a column.

More about using the control you can get by reading this article here at CP:

windows CE, change display contrast

Hello!
i'm trying to change the contrast of my windows CE 4.2 device.
After some search on the net i found some methods to change the contrast,
all based on ExtEscape() function. Unfortunately ExtEscape always returns 0
on my device, no matter what escape code i pass to it.
This is a snapshot of my code:

bool SetContrast(int nParam)
{
ContrastCmdInputParm ContrastParm;
int rc, fQueryEsc;

fQueryEsc = CONTRASTCOMMAND;
HDC hdc= GetDC(NULL);
rc = ExtEscape (hdc, QUERYESCSUPPORT, sizeof (fQueryEsc),
(LPSTR)&fQueryEsc, 0, 0);
if (rc == 0) {
// No support, fail.
ReleaseDC (NULL, hdc);
return false;
}
ContrastParm.command = CONTRAST_CMD_SET;
ContrastParm.parm = nParam;
int nCode= ExtEscape(hdc, CONTRASTCOMMAND, sizeof(ContrastCmdInputParm),
(LPCSTR)&ContrastParm, 0, NULL);
ReleaseDC(NULL, hdc);
return (nCode > 0);
}

This function always fail with no support.

Can anyone help me?

Did you try WinDbg[^]? It's not very easy to use, it's a command line debugger, but it might offer you valuable clues to debug the problem.

You can handle the CWnd::OnCtlColor / WM_CTLCOLOR message in your dialog class, and return a brush of your choice.

Windows will then use that brush to paint the background of a control.

Do a search for OnCtlColor in msdn, and it will even give sample functions.

Good luck,

Iain.

Create a window that never gets input focus

Hi!

How can i create a window that just hangs around without ever getting focus/becoming active.. yet let the user interact with it through mouseclicks? Smile | :)

I want a window that is open, on top of the screen, that does not break the focus on currently focused application. That is, if i have a webpage open such as this.. and i'm writing in a textbox, i can press a button (to change mixer volume for example) and keep writing without having to click in the form.

Hope it's possible! Would sure open a lot of doors for me!

Thanks for reading! Big Grin | :-D

The moment you click on it the window will get focus, I don't see how you can avoid this unless you return focus to the previous window at the end of each event.

Well, I have seen this behaviour in a few applications (mainly professional on-screen keyboards). If you fire up the virtual keyboard that ships with windows xp you will see what i mean. it does not get focus when you click on it's buttons! if you click the titlebar however, it does.. but gives it back to the application that previously had focus whenever you hover the buttons on it. I want to remove all decorations and display only buttons that act just that way (i know how to change focus back to previous window, but that's not what i want).

Thanks! Smile | :)

As Elaine said, the only way to achieve that is to give the focus back to the window that lost it immediately after getting it in your app.

Intercept WM_SETFOCUS, the wParam is the handle of the window that just lost the focus (Win32 version) or in the CWnd::OnSetFocus method, you get a pointer on the unfocused window CWnd *pOldWnd(MFC).

Then use SetFocus in your turn with this handle (pointer) to yield the focus back to the window that lost it.

would intercepting WM_SETFOCUS be any different from calling SetActiveWindow(NULL) within the procedure of the button click?

I tried this:

<br />
LPDWORD pid, hpid;<br />
GetWindowThreadProcessId((HWND)wParam, pid);<br />
GetWindowThreadProcessId(hwnd, hpid);<br />
<br />
AttachThreadInput((DWORD)pid, (DWORD)hpid, TRUE);<br />
SetFocus((HWND)wParam);<br />
//SetForegroundWindow((HWND)wParam);<br />
AttachThreadInput((DWORD)pid, (DWORD)hpid, FALSE);<br />

with no success (it does not move focus).

        case WM_SETFOCUS:<br />
	{<br />
		LPDWORD pid, hpid;<br />
		GetWindowThreadProcessId((HWND)wParam, pid);<br />
		GetWindowThreadProcessId(hwnd, hpid);<br />
		<br />
		AttachThreadInput((DWORD)pid, (DWORD)hpid, TRUE);<br />
		SetActiveWindow((HWND)wParam);<br />
		SetFocus((HWND)wParam);<br />
		SetForegroundWindow((HWND)wParam);<br />
		AttachThreadInput((DWORD)pid, (DWORD)hpid, FALSE);<br />
		printf("Focus changed %d", wParam);<br />
	}<br />
	break;<br />

seems to retain the focus on the app as long as i do not doubleclick on my panel.. button procedure is not caught though.

this does not work with Firefox. If i am editing in the location bar and press the volume button.. the whole url in the locationbar gets selected.. which means that i will overwrite whatever was previously written if i type something on my keyboard (unlike if i use the windows virtual keyboard).

That is the correct statement if you have windows on c:. Where did you put this statement? The best place is near the bottom of stdafx.h.
