YES. I already set them to 1600.
void CTRYView::OnInitialUpdate()
{
CScrollView::OnInitialUpdate();
CSize sizeTotal;
// TODO: calculate the total size of this view
sizeTotal.cx = sizeTotal.cy = 1600;
SetScrollSizes(MM_TEXT, sizeTotal);
}
BUT no benefit?

use the setscrollsizes() function just before u try to load the image on the screen.
there is no need to handle drawing on scroll, onDraw automatically is called.
to avoid the flickering problem, u can try using memory DC by using the CreateCompatibleDC() and CreateCompatibleBitmap() functions. once the drawing is done, use the BitBlt() or stretchBlt to draw this to ur main Device context.

YES u are right . I called setscrollsizes() in OnInitialUpdate() whereas I load the bitmap against a menu click but still it is not working.

Hello,
I use this snippet to send message. m_pTextBlockFocused is a windowless RichEdit host class.
LRESULT lr;
m_pTextBlockFocused->GetTextServices())->TxSendMessage(EM_SETBKGNDCOLOR, 0, RGB(0,0,255), &lr);
The return value lr is 0. But in my opinion, that should be 0x00FFFFFF. By MSDN, this call should return the previous RGB value of background - white background.
Thanks,
Xiang

Dear All,
I want to disply the character ♠ in the CEdit but this only getting diplayed when I change the project settings to Unicode. But to display this single character, I need to change my entire project which seems a huge task for me.
I planned to do some alternative for this. Is it possible to extend a CEdit class to display unicode characters and then to include that class to my main project without changing the existing settings of my main project.
Please advice me.
Many thanks in advance.

CDC *pDC = GetDC();
CFont m_Font;
LOGFONT lFont;
memset(&lFont, 0, sizeof(lFont));
lFont.lfHeight =
MulDiv(20, ::GetDeviceCaps(pDC->m_hDC,
LOGPIXELSY), 12 );
lFont.lfWeight = FW_NORMAL;
lFont.lfOutPrecision = OUT_TT_ONLY_PRECIS;
wcscpy( lFont.lfFaceName, _T("Lucida Sans Unicode"));
// Set the Font
m_Font.CreateFontIndirect(&lFont);
// Set the specified font for the edit ctrl.
m_edit.SetFont(&m_Font);

Dear ARJ,
Many thanks for your reply. The real problem is that the above code will work only if we set the project properties to Unicode otherwise the above won't work.
I want to display those control characters in CEdit without changing my main project's project setting to Unicode.

I am not sure but try creating the edit window as unicode. I mean you have to create the windows dynamically using the CreateWindowW ( the unicode version of CreateWindow ).

I'll recommend that you convert your project to Unicode, and it is the ideal way of doing it. Unless your code uses some kind of a third party library that doesn't support Unicode, I don't see a reason why you should not do a fully Unicode build. You can always come here and ask questions if you run into trouble.

Hi,
in my application i have a requirement to check the internet connection. The situation is my laptop is connected to LAN, and the outgoing internet trafiic is down(LAN is UP so i have the local IP). So i need to check this thru some c++ coding. I am basicaly using win32 . can you please help me out.
I know the api InternetGetConnectedState(), but it always gives connected ,though i have connected to LAN.
Do you have any idea how to detect that....

It looks like you did not read the remarks section of the API in the doc?
Take a look at InternetCheckConnection()[^]. With this function, you will be able to specify a URL that the API should check connectivity to.

What URL did you try with this call?
Are you able to reach that URL manually from that particular machine?
Do you have a firewall? Is it configured to allow this application for outbound traffic?
What does GetLastError() say?

It is giving 12006 "The URL scheme could not be recognized, or is not supported." error.I tried with giving "google.com" in url field
Incase of NULL in url field it is giving 12016 "The requested operation is invalid." error.
Do you have any idea how to resolve thse errors. Obviously I am able to ping google.com from my machine.

You tried passing "google.com" as the lpszUrl field value?
The documentation has a description for this field, and that says: Pointer to a null-terminated string that specifies the URL[^] to use to check the connection. Notice that URL has a syntax.
A valid URL that can be passed as lpszURL would look like: _T("http://www.google.com")
Also, take a look at the example provided in MSDN for InternetGetConnectedState[^]

I am capturing the screen by using GetDesktopWindow(). Now I want that when ever desktop (captured screen)changes/updates, I get the information, so that I would capture it again.
I have heard the word " window hooks" but do not know how to apply it. please guide?
The application is MFC based.

LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam)
{
int x=12;
if (nCode==HCBT_MINMAX)
{
AfxMessageBox(_T("Called"));
}
return 0;
}
CSDITESTView::CSDITESTView()
{
SetWindowsHookEx(WH_CBT,&CBTProc,NULL,0);
}
After reading the mentioned article, I wrote these lines, but it is not working? I am expecting that when I minimize the window , the associated call back function should be called.

Hello i searched on the web but didnt find any good info how to do it. Could anyone post a example or refer me somewhere where i can read up on them i would like to hook a function using opcodes.
Thnx

NT based API hooking is also good
is it really necessary for you to hook with the functions using op codes.
otherwise my suggestion is
NT based :-
API hooking revealed[^]
kernel based:-
API Hooking (LoadLibrary)[^]
