Have you tried ODBC with CRecordset and CDatabase?

Hi , How does following code works.
int s = 0 ;
printf("%d" ,s["123456789"]); //Output 49
printf("%d",s["987654321"]); //Output 57
printf("%d",s["9"]); //Output 57
Please provide any comments on this...

The "so-called" code is returning the ASCII base-10 value of the first character in the string.

There's a couple of factors at play here:
- Array accessing -
array[index] can be rewritten as index[array] (it's all because of the syntax of PDP-11 assembly language, in which and for which the first C compiler was written). So, with s==0,
- s["123456789"] == "123456789"[s] == "123456789"[0] == "1" == 49 (ASCII code)
- s["987654321"] == "987654321"[s] == "987654321"[0] == "9" == 57 (ASCII code)
- s["9"] == "9"[s] == "9"[0] == "9" == 57 (ASCII code)
- When you use the format string "%d", printf interprets the next argument on the stack as an integer. Items on the stack are aligned on 4-byte boundaries, so characters can be read as integers, which means that the ASCII code of the character is printed (so long as the character is zer-extended before it's pushed onto the stack).

20 years of reading stuff combined with a (very) good memory  You may have had an annoying classmate at school who never seemed to have to study for exams? Yeah, that was me - learning stuff just sticks with me.
Remembering peoples names or what I was doing last week? Nah, can't do that!

Hi!
I'm having a problem placing a transparent window over a window of a foreign application. Description:
1. I create a transparent window with controls on it(Transparency color = RGB 255,0,255)
2. I'm searching, finding a window of a foreign application and set my window on it (via SetWindowPos(Foreignwindow, Mywindow)). it works.
3. If the foreign window is minimized, my window has to minize, too. After maximize...my window should maximize, too, but the order of the windows should be the same....my window over the other
4.If the user opens another window e.g. Notepad and Notepad is topwindow...my window should be visible, to as long as the foreign window is opened but the ordering should last. So notepad is at top, my window is the next and the foreign window.
Example:
-Foreign Window, above...
-Mytransparent window
Notepad opened...
-Foreign Window, above...
-Mytransparent window, above...
-Notepad
My transparent should always positioned over the window and always visible if the foreign window is visible. If the foreign window is not visible, my transparent window shouldn't be visible, too.
How to do it? someone has an idea or code?
Thank you very much and excuse my bad english.

You should install a CBT hook to track window minimize/maximize and move/resize.
Look at SetWindowsHookEx[^] for WH_CBT.
To keep the window on top of a particular window, try and use SetParent[^]

Hi! Thank you for your answer.
I did not try the hook, i want it all in one app if possible.
I tried to set the parent and it works....but...the foreign window is a subwindow of another window (let's call it mainWin). After SetParent(child,parent) my transparent window was over it and visible. But after clicking the main window, the main window did not get the focus and my transp. window was shown. After clicking the transwindow the mainwindow was shown. Any other ideas?
Thank you very much!

Hi and thanks! No...not helpful. The article is about the games memory...mainly.
The overlay works a bit...only the activating and focussing doesn't work.
I got an example software for that www.pokertracker.com has overlays, too.

Add Window Message WM_CTLOLOR

HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
HBRUSH hbru = ::CreateSolidBrush (RGB(255,255,255));
if(pWnd->GetDlgCtrlID() == IDC_EDIT_SERVER)
{
pDC->SetTextColor(RGB(0,0,0)); //Set TExt color

return hbru;
}

If the edit control is always read-only, why not just make it a static control?

What is the exact error message(s) ?
You realize that your question is totally vague ?

I get a lot of Compile time errors (C2872)
CCriticalSection Ambiguous Symbol.

Are you redefining a CCriticalSection object somewhere in your own code ?
