Good C tutorial needed.
Hint: string literals must be enclosed by double quotes.

What in the world is this?  The documentation plainly shows that MessageBox() expects four arguments.

Hi,
I have been created a tab control in dialog box (we called as Dialog Main). I add 3 frameless dialog box (we called as dialog A, Dialog B, Dialog C) in the tab control. The tab control working fine. I add three button (OK button, Cancel button ,Apply Button) in each frameless dialog box. However, when I clicked Cancel button in dialog A only dialog was closed. I want all dialogs(Dialog Main, dialog A, Dialog B, Dialog C) to be closed when I clicked OK of Cancel button inside each frameless dialog box(dialog A, Dialog B, Dialog C). Please anybody help me???

Use AfxGetMainWnd()->PostMessage( WM_CLOSE ).

Hi,
Actually i'm calling dialog box from SDI application.
When i use Use AfxGetMainWnd()->PostMessage( WM_CLOSE ) the whole application was closed.
I just want just dialogs(Dialog Main, dialog A, Dialog B, Dialog C) to be close.

You can then post this message(WM_CLOSE) to your dialog, or call EndDialog on this main dialog of yours.

GetParentOwner()->PostMessage( WM_CLOSE );
or
::EndDialog( GetParentOwner()->GetSafeHwnd(), IDCANCEL );

It sounds like you'd be better served by a property sheet (with three property pages). In this context, the buttons would belong to the whole sheet rather than a particular page. Way cleaner than your current design.

I use CWebBrowser2 to open web page:
CWebBrowser2 m_webBrow2;
m_webBrow2.Navigate("http://www.google.com",NULL,NULL,NULL,NULL);
When web page has been opend, I can put "my search" into google's search edit control by keyboard and press search button by mouse.
But, how to do these by C++ code?
Is CWebBrowser2 have member can do this?

Directly use a search query string. Modify navigation string to include the search term too! Click on this link and see what happens, and the same you can do with the navigate function!

thanks.
But, google.com only a sample. If web page is an other and if after press a button web page not change to another page?
So, I cannot work on all web page by this way.

good question, i'm trying this to for a while but I haven't found anything, do you?

I have DIB information - header and color array retrieved from video frame.
I like to get very basic histogram of RGB colors. I am having difficulty understanding the difference between bitmap dimesions biWidth, biHeight and biSizeImage. All in bytes.
I understand that the biSizeImage is much larger than simple width*height because it does scan lines adjustment and other stuff.
If I run do ( ….) while (count != width*height) I must be “counting” some of these adjustments, right?
But if I run do(…) while (count != biSizeImage) it asserts probably because it runs out of real bitmap data.
(I have not traced it all the way to the point of assertion.)
So – how do I skip over the “fillers” or do I have to run GetDIBits and build another data buffer?
Thanks for reading

I think I found the solution - two nested for loops from 0 to width/ height. Testing.

Yes
Example:
LONG stride = (((bmiHeader.biWidth * (long)bmiHeader.biBitCount + 31L) & (~31L)) / 8L);
RGBTRIPLE *CurrentRow = ...address of beginning of pixel data...;
for (int y = 0; y < bmiHeader.biHeight; ++y)
{
for (int x = 0; x < bmiHeader.biWidth; ++x)
{
... do something with CurrentRow[x].rgbtRed ...
... do something with CurrentRow[x].rgbtGreen ...
... do something with CurrentRow[x].rgbtBlue ...
}
CurrentRow = (RGBTRIPLE *)((BYTE *)CurrentRow + stride);
}

Thanks Mark,
somehow I knew that simple loops won't work.

You can use a single loop as long as the values of any possible row
padding bytes doesn't affect your math, but you still have to know
the extra bytes may be there.
Also, biSizeImage is allowed to be 0 - you need to check for that and calculate
the value if it is:
if (0 == biSizeImage)
biSizeImage = stride * abs(biHeight);

Mark , thanks for the addendum.
But I spoke too soon. My code still asserts. My bitmaps size is 320 wide and 240 high and it asserts in about half height. I must have screwed up something. It looks like I do not have 24 bit biBitCount.
But right now I have another pressing issue ( babysitting my new grandson!)so this one is temporary on hold. Here is my code in case you want a good laugh.
As always "->" are = -> !
I do not understand why this editor does that to my code! Tired of "fixing it"!
PS. It seems to make no difference if I use casts as you suggested.
RGBQUAD *CurrentRow;
//lpBi->bmiHeader.biBitCount = 32;
LONG stride = (((lpBi->bmiHeader.biWidth * (long)lpBi->bmiHeader.biBitCount + 31L) & (~31L)) / 8L);
if(lpBi->bmiHeader.biBitCount == 24)
CurrentRow = lpBi->bmiColors; // 24bpp pixel data - use RGBQUAD
else
{
//AfxMessageBox("Unsuported bitmap format");
}
CurrentRow = lpBi->bmiColors;
for (int y = 0; y < lpBi->bmiHeader.biHeight; ++y)
{
for (int x = 0; x < lpBi->bmiHeader.biWidth; ++x)
{
iRed = CurrentRow[x].rgbRed;
iGreen = CurrentRow[x].rgbGreen;
iBlue = CurrentRow[x].rgbBlue;
/*
histogram[RED][iRed] += 1;
histogram[GREEN][iGreen] += 1;
histogram[BLUE][iBlue] += 1;
*/
icount++;
}
CurrentRow += stride;
}

Change
CurrentRow += stride; to
CurrentRow = (RGBQUAD *)((BYTE *)CurrentRow + stride); I changed that in my original reply code
