I tried the following:
BOOL CMyFormView::PutDataToClipboard(CBitmap *pBmp)
{
COleDataSource *pods = new COleDataSource;;
HBITMAP hBmp = (HBITMAP) *pBmp;
int i = sizeof(*pBmp);
HANDLE hData = ::GlobalAlloc(GMEM_FIXED, sizeof(*pBmp));
CBitmap* pData = (CBitmap*) ::GlobalLock (hData);
pData = pBmp;
BOOL l = ::GlobalUnlock(hData);
STGMEDIUM stg;
stg.tymed = TYMED_GDI;
stg.hBitmap = hBmp;
stg.pUnkForRelease = NULL;
// Place the data object on the OLE clipboard.
CFormApp* ab = (CFormApp*)AfxGetApp();
pods->CacheData(CF_BITMAP, &stg);
pods->SetClipboard();
//ab->pods->CacheData (CF_BITMAP, &stg);
//ab->pods->SetClipboard ();
delete pods;
return TRUE;
}
I'm unable to paste the bitmap in mspaint (and other places). Any ideas?

Hi everybdody.
I got a simple question.
How could I load some html file that I already have as resource, into an CHtmlView???
My initial idea was load the file using the Navigate2 function from OnInitialUpdate() but I can't see how.
Thank you for your time.
Demian.

Try looking into the res: protocol[^]. It's a way of specifying a URL that refers to a resource in a DLL or EXE.

I'm running into a problem that seems like it must be solvable, but I can't find any documentation that explains it.
The basics: I have a custom control that uses a bitmap for a background (either created programmatically, or by loading a resource or file). This is done in an off-screen memory DC to avoid flickering. After the bitmap is rendered, I render some text onto it using DrawText() API. When it's done, the whole thing is blitted back onto the screen.
The problem: When ClearType is enabled, the text looks ugly, almost as if every letter has a black outline around it. I'm guessing this is the sub-pixel antialiasing stuff, which has somehow turned black when I blit from the memory DC to the screen.
Question: how can I allow and use ClearType in my control and still have it look okay? Apps like IE and Firefox handle ClearType correctly, and I'm pretty sure they're using some kind of off-screen double-buffering scheme for drawing, so it seems to me there should be a way to do it. But I'm darned if I can figure out how.
Thanks in advance for any help,
Warner Young

I had a similar problem the other day, i found the cause was when drawing of screen, I didn't create a compatible bitmap with the main DC. Have a look at how you are implememnting your double buffer, the problem may be there.

Is the bitmap that is selected in the memory dc a bitmap that is compatible with the screen? Or did you just select the bitmap that you created/loaded into the memory dc and try to draw the text that way? Some sample code would help since I don't have any problem drawing cleartype enabled text on my doublebuffered controls.

I am inferring some things from my learning experience with VC++. I'd like to check if I am correct.
1. Each file is compiled separately and independently. This means each .ccp and .h file is compiled as a stand alone unit.
2. If #1 is correct, then each file must contain all the class and function declarations to which any code in that file will refer.
3. The same header file with class declarations can be #included in several other files. In other words, trans.h can be included in both abc.ccp and xyz.cpp.
Is this correct? Thanks.

*.cpp files are compiled, not *.h files. CPP files are where the implementation for classes, functions, etc are placed. H files are where they are defined. This allows other modules (classes, libraries, etc) to see the definition of a function or class without having to know how everything is implemented during the compilation.

You can't use a function/class/variable/etc unless you know how it is defined.

This is correct. Though usually you place #pragma once or #ifdef/#define statements around the header file content to prevent a file from being included multiple times.

it helps to think of #include "foo.h" as doing exactly what "include" implies: the preprocessor reads the contents of foo.h and, in effect, sticks that in the place of the #include line. the compiler doesn't really look at foo.h directly.
and, you can #include anything.

Hey,
how can I draw a rotated ellipse with MFC. The only way I found out to draw ellipse is to use CDC:Ellipse. The way requires a rect...
Is there any other way?
Thank you for your help

One way would be to draw it unrotated and then to use CDC::ModifyWorldTransform to do the rotation.

For online sources ... use Google.

Yes, but you have to pay for it. The C++ standard is available in PDF from ANSI here[^] (costs $30).

From people that know, are skills in VC++ translateble to the embedded / mobile version? What are the main differences?

To some degree. Mobile SDK is usually only a subset of the regular SDK, with some mobile extensions.

In general, the embedded version of the SDK is a subset of the non-embedded version. Basic C++ skills are the same, but you do have to take extra care when dealing with memory allocation and stack limitations.

When I am using CryptEncrypt() & CryptDecrypt()functions in my VC++ project which is UNICODE, I'm getting junk values after decrypting. But when the project is _MBCS(Multibyte-character) it is working fine. Did any of you encountered this problem ?
Is there a workaround ?

can you post the relevant parts of your code?

hi all,
i am creating multiple objects for the same class
like calling this function as many times.
Void CMainWindow::OpenDefaultChatwindow()
{
m_dlgChatWindow = new CChatWindow();
m_dlgChatWindow->Create(IDD_DIALOG_CHAT_WINDOW,GetDesktopWindow());
m_dlgChatWindow->SetNewParent(this);
m_dlgChatWindow->ShowWindow(SW_SHOW);
}
but when i delete the object i am able to delete only one object then it is showing memory leaks
because i created multiple same objects and deleting only one object.
How to solve this problem ?
plz help in this issue
