I am using a C library which contains functions that use FILE* to send data to a file. Since I am writing my code in C++ and using ofstream, is there a way to gain access to the underlying FILE variable that is nested in ofstream to send to these functions?
Any help will be gladly accepted.

I am not familiar with C and FILE *. However, ofstream does have a function that returns a pointer to the data buffer.
rdbuf()

I do believe it is in stdio.h

No, at least not in a portable way. You might cheat by hard-coding for a particular implementors specific version of the C++ library, but since that's a really ugly thing to do I obviously can do nothing but strongly recommend against it.
Now, what you can do is drop the f requirement and use ostream. Then you could instantiate a basic_ostream class that is implemented with a specialized streambuf that both uses and exposes the C stream interface (using FILE*).
Since this is almost a FAQ, I refer you to google and/or comp.lang.c++.moderated for further information.

You need to roll your own bitmap save function (BITMAPCOREHEADER and BITMAPINFO) or search for "bitmap saving" at codeproject (27 hits)(multiple file formats).
Trust in the code Luke. Yea right!

look code:
IHTMLDocument2 *m_spActiveDoc2;
LPFNOBJECTFROMLRESULT pfnObjectFromLresult;
DWORD dwMsg;
LRESULT lRes;
HRESULT hr;
dwMsg = RegisterWindowMessage("WM_HTML_GETOBJECT");
SendMessageTimeout(hControl, dwMsg,0,0,SMTO_ABORTIFHUNG,1000,(DWORD*)&lRes);
pfnObjectFromLresult = (LPFNOBJECTFROMLRESULT)GetProcAddress(hInst,"ObjectFromLresult");
if(pfnObjectFromLresult != NULL)
{
hr = (*pfnObjectFromLresult)(lRes,IID_IHTMLDocument,0,(
void**)&m_spActiveDoc2);
if(SUCCEEDED(hr))
{
IHTMLElement *m_spActiveElement;
hr = m_spActiveDoc2->get_activeElement(&m_spActiveElement);
if(SUCCEEDED(hr))
{
BSTR TagNameBStr;
AnsiString TagName;
BSTR LocationURL = NULL;
m_spActiveElement->get_tagName(&TagNameBStr);
TagName = AnsiString(TagNameBStr).UpperCase();
if(TagName == "A")
//here I can't get "option" or "select" object,why?but others ,like A,INPUT,..., i can get it!

This is a very complex area, that has seen considerable billion of dollars of both corporate and academic research, and still the best that has been produced (to my knowledge) is Dragon... (speak? talk? Something like that).
I think the best you could do is either this link or buying an existing solution.

look for sapi in the internet and download the latest sdk from microsoft...
there are samples from Microsoft in the sdk too...
it seems that sapi 5 is not well documented as sapi 4...
Hope this helps...
PS:
I've tried to handle those things, but as I don't wand to use english (and I have no time to test it) I have not been able to get it to work... (by now...)

Hi,
i'm implementing a splitted frame window with a CListView on the top part of the window and a CFormView on the bottom. When i click on an item of the list in the form i want to visualize the informations of that element (some kind of Master/Detail logic).
The problem is that when i focus in the form the selection in the CListView disappeared. If i re-focus the list the selection appears again. There's a solution to prevent this disappear?
Thanks

i made a toolbar using this command: hToolBar = CreateToolbarEx(hToolBar, WS_CHILD|WS_BORDER|WS_VISIBLE, 2, 123, hInstance, IDR_TOOLBAR1, array, 8, 87, 33, 87, 33, sizeof(TBBUTTON));
it shows but when i resize the window the toolbar doesnt resize accordingly. i tried to make it update using: SendMessage(hToolBar, TB_AUTOSIZE, wParam, lParam);
and
SendMessage(hToolBar, WM_SIZE, wParam, lParam);
but it doesnt work. What should i do to make it update?

Hi,
have you tried SetWindowPlacement, instead of sending a WM_SIZE message instaed?

I have a listctrl where i can set any row to use a new font, the main problem i had was that on changing the font the rows/columns would not resize correctly to take account of the new text extents.
After searching on this site and then looking on MSDN, i now send a CCM_SETVERSION 5 message to the listctrl before i add any items.
This now makes the column widths resize correctly, but the row heights are still wrong.
I've spent many hours trying to find a way to fix this but have made no progress.
Hoping you can give me some ideas.
BTW it's a NW_CUSTOMDRAW listctrl not an ownerdraw.

If you can't get it to work, create an imagelist without images and then assing that imagelist to your listctrl, the rows will have the Images height...
I suppose that you will be able to readapt the heights as you want using this trick...
Hope this helps...

Hi,
I'm trying to make some MultiThreaded OpenGL code work in release mode.
Normaly it just comes up as a grey screen in release but works fine in debug.
I've eliminated it being an Optimisation error and have managed to recreate the error in Debug mode by adding NDEBUG instead of _DEBUG.
Before I start delving into this properly I was wondering if anyone has had the same problem, re: OpenGL.
Cheers
