How to use setwindowpos with MDI

16-Jan-04 14:05

its not a mdb anymore
its a service running in the background like a proper database
u need to set up an odbc link to it and maybe (this is the horrific part) change ur sql queries cos the syntax is different
msde uses "standard" sql whereas access (jet) didnt

Do you have Access? If so, it includes a tool to 'upgrade' your database to SQL Server form. It isn't perfect, but it's a start. In theory, a MSDE database is identical to one made with SQL Server. Try the tool, if you have it, then check the docs on MSDE at MSDN for linking it all together.

For one, you no longer have MDB files, you have MDF and LDF files. However, these files are not self-contained like the MDBs, so you can't just move them around. It's best to let SQL Server deal with it if you're just starting out.

For two, if you're using DAO to connect to Access, I'd recommend switching to ADO if possible.

For three, to *easily* manage your database, you'll need a replacement for a tool for a program that comes with the real SQL Server called Enterprise Manager. Here's one such replacement...

And lastly, SQL Server comes with many tools that MSDE does not. One in particular is the DTS wizard and editor. You can run a DTS package with MSDE, but not create one (unless you do everything via code that is).

The last I heard Microsoft was selling SQL Server Developer Edition for only $49. It's way better to develop your DB with the real deal, and then just bring it over to MSDE when you're done.

CMDIChildWnd * pChildFrm = ( CMDIChildWnd * ) pView -> GetParentFrame();
pChildFrm ->GetWindowRect( wkRect );
::SetWindowPos( CMDIChildWnd ->m_hWnd, &wndNoTopMost, Pos.x, Pos.y, wkRect.Width(), wkRect.Height(), SWP_SHOWWINDOW);

Retrieving proxy info from IE settings

Hello all

I want to program an application which has to retrieve info reg whether the browser is using the proxyserver or not. I found this information in registry under

HKEY_USERS\S-1-5-21-1614895754-1647877149-839522115-500\Software\Microsoft\Windows\CurrentVersion\Internet Settings

But I would like to know whether this works on all windows machines or not. If there's any better way of retreiving this information, pls suggest.

Thanks for your help.
Hari.

Hi,

Do you want to do that programatically ? HKEY_USERS info is user based. You will find similar such settings under HKEY_LOCAL_MACHINE too.

GetPixel() help needed

__Cerb16-Jan-04 10:59

Ok, I know how to use the GetPixel function, the only problem is that I must get the DC of an inactive/minimized window. I've tried HDC hdc = ::GetWindowDC(hwnd), HDC hdc = ::GetDC(hwnd), HDC hdc = ::LockWindowUpdate(hwnd), but all of them returns -1 when I call the GetPixel function on any pixel of that DC.

If I can figure this out, it would GREATLY help my project.

Thanks a lot in advance

You can't get pixels from a minimized window. There is no "canvas". Smile | :)

So in no way I can do this?

Damn, that sucks. With this, my project would have been so great...

Not to my knowledge, no. The device context mirrors what's shown on screen. If there's nothing on screen, then there are no pixels to grab.

This window you're trying to snatch pixels from.. is it in the same process as your pixel grabbing routine? If it is, you could always make the "source window" double buffered. That is, it keeps a bitmap of itself internally. That way you could access the bitmap for pixels. Otherwise it's a pretty tough job I reckon.

By the way, after GetPixel() returns -1, have you checked the error code? Either call GetLastError() or add the @err pseudo-variable in the watch window in the debugger.

Well, I have a game window opened and minimized, I'm using ::FindWindow to get its HWND value, I tried all possible ways to get the window's DC, but couldn't.

Would it be possible to get a bitmap or a BitBlt and get the pixel I want from it? If so, how could I do it?

Thanks a lot for your help

i think u can send it a wm_paint message and pass a dc in
then it draws to that dc
and u can grab what u like

Uh? Pass a DC in a WM_PAINT message?

How do you do that?

I doubt it's possible...

Uh this won't work. Sending a message to a window is not like retrieving a HDC, so it won't return the HDC of the window.

l a u r e n16-Jan-04 15:17

16-Jan-04 15:17

dude
u pass the hdc in as athe wparam and the app _might_ paint on it
if ur lucky
i thought that was what u wanted?

I don't think it'll work with WM_PRINT. HDCs are inprocess handles I believe (not entirely sure about that though). Sending an HDC from one process to another will at best result in nothing. I think the only way is to grab a handle to the window, and then acquire a HDC from that window handle.
