It's a butt-ugly kludge (well, the whole program is at this point, but that's not the issue. Smile | :)

).

Compact Framework graphics

Hi,
I need to build a quick and dirty front end for a prototype on a Pocket PC. I don't mind what I use, but I'd prefer C#/.NET, and I don't have any serious graphics experience. The key feature I need is to be able to rotate a graphic - could be a bitmap, or could be dynamically drawn. The functionality I want to reproduce is basically System.Drawing.Drawing2D.Matrix.Rotate() in the full framework, so I can rotate images.

So without having to dive into graphics drawing first principles, and hoping to avoid any explicit math in calculating a redraw, are there any examples or pointers to how to do this in the CF?

I guess I also need to ask about double-buffering and managing the form's background repaint to avoid flicker.

If you think I should stick with C++ for this then I'd be grateful for a pointer or two instead - not asking much Smile | :)

Thanks in advance
Rich

Take a look at James Image Rotation in .NET article.

I hope this will help you!

Thanks Daniel.
The Math looks helpful, but the CF doesn't support the point[] that James uses to define the screen coordinates of the (rotated) image vertices. The CF only allows me to specify the (X,Y,Width,Height) at which to draw a bitmap. I think I can use the math however to create a rotated bitmap in memory and draw that at (1,1).

Cheers,
Rich

I seem to recall that the window you give as part of the notification structure gets posted a WM_COMMAND message. There's a sample application in MSDN/eVC Help that shows this in detail.

I'm trying to make a little demonstration of WML pages on Smartphones/Pockes PC's. Why is it so hard to get a little emulator for that ? I just installed eVC++ 4.0, sp2, Pocket PC sdk just for a little emulator ...
Now can someone please tell me how to start the emulator, cause there's a lot of documentation on using the emulator but nothing on where is located or how to start it ....
Excuse my stupidity but it's the first time I use these tools ...

You have to have a new version of the .NET Framework on the desktop for the Compact Framework functionality to work. Also, if you use anything like SQL CE, or hardware P/Invokes.

Scrolling dialog in CE

#realJSOP12-Dec-03 3:25

Re: Scrolling dialog in CE

12-Dec-03 3:25

Well, it was bound to happen. One of the managers has complained that when the keyboard is displayed under PPC2K, it sometimes (depending on the dialog box) hides the edit control that's being changed.

I've now got to figure out a way to scroll controls within a dialog box, and it has to work on property pages as well, including wizard pages.

Grrrr....

QA: How do I scroll the contents of a dialog?[^]

Regards,
João Paulo

#realJSOP12-Dec-03 6:23

Re: Scrolling dialog in CE

12-Dec-03 6:23

Close, but I have special requirements. Smile | :)

1) I can only have a vertical scrollbar.

2) The scrollbar can only be displayed when the SIP is active.

3) The scrollbar has to fit between the titlebar and the active SIP keyboard.

I've got the scrollbar working, but now I have to figure out how the dialog box can tell when the SIP is active/inactive.

It ain't pretty, but what I have up to this point works pretty well.

What I think I eventually want to do is have the dialog box create the scrollbar control on the fly instead of planting a control on the dialog box in AppStudio.
Smile | :)

No problem. Just make sure that what's inside the dialog plus a vertical scrollbar width is less than or equal to the screen width (150 dialog units for Tahoma 8). The horizontal scroll bar will be gone.

John Simmons / outlaw programmer wrote:

As a matter of fact, this code already does what you need. Try reducing the dialog to 150x146 (dialog units) and remove the extra controls. Now run the demo and open the SIP. Voilá! You will have to make sure the contained dialog position is restored when the SIP goes down (not implemented in the code).

Also done on the previous point.

You will need to remove the header. Add these lines to the top of the CScrollDialog constructor:

if(m_strTitle.GetLength() == 0)
	m_nHeaderHeight = 0;
else
	m_nHeaderHeight = 22;

and at the top of CScrollDialog::PaintHeader:

if(!m_nHeaderHeight)
	return;

Now, when declaring the dialog, use this:

CScrollDialog   dlg(_T(""));

I´m looking into the SIP down correction...

This is the code I came up with to setup the scrollbar in OnInitDialog():

GetClientRect(&m_DlgClientRect);
m_ctrlScrollBar.Create(SBS_VERT | WS_VISIBLE | WS_CHILD | WS_CLIPSIBLINGS, CRect(0, 0, 10, 188), this, 12345);
m_ctrlScrollBar.GetWindowRect(&m_ScrollBarRect);
m_ctrlScrollBar.MoveWindow(m_DlgClientRect.Width()-m_ScrollBarRect.Width(),0, m_ScrollBarRect.Width(), m_ScrollBarRect.Height());
m_ctrlScrollBar.BringWindowToTop();
m_ctrlScrollBar.ShowScrollBar();

m_ctrlScrollBar.GetWindowRect(&m_ScrollBarRect);
 m_nScrollPos = 0;
 m_nCurHeight = m_ScrollBarRect.Height();
 SCROLLINFO si;
 si.cbSize = sizeof(SCROLLINFO);
 si.fMask  = SIF_ALL;
 si.nMin   = 0;
 si.nMax   = m_DlgClientRect.Height();
 si.nPage  = (int)(m_DlgClientRect.Height() * 0.7);
 si.nPos   = 0;
m_ctrlScrollBar.SetScrollInfo(&si, TRUE);

I know - it's not pretty, but it works... Smile | :)

The code above sets up the scrollbar so that it's initially visible for testing purposes. The rect size used in the Create() call is based on the size of the keyboard SIP.

Problems with GROUP BY clause...

12-Dec-03 8:05

I actually only need to know when the user brings the SIP up, and when he shuts it down. My scrollbar will only be visible when the SIP is up.

Hello all,
I am using ADOCE 3.1. The following SQL statement

SELECT ck_iParamId,ck_ParameterSource FROM  t_HCMHISTORY WHERE ck_iDeviceId = 1000 GROUP BY ck_iParamId,ck_ParameterSource

which executes quite peacefully in SQL Server 2000 throws an exception "(0x80040e14) : The command contained one or more errors" when executed on PPC 2003.
However, if I execute the same without GROUP BY, it works as normal.
Are there any limitations wrt GROUP BY clause ?
Any suggestions are welcome.
Thanks.
Amit
