I noticed the explorer properties that used to show in XP for my MFC generated files are gone in Vista. I did find something about including XML file .propdesc file to include properties that I need the file to have... Any one dealt with this before?
Thanks

Hi, does anyone know where sources for B/B+ tree implementation can be found?
The main requirements are:
- fast access to an element by index
- fast writing to a file

Nobody knows about, even Wikipedia [^], [^] (and you surely won't find links to C/C++ implementations at the bottom of the pages).

Hi
I have a MDI application. I don't want to use MDI default "ID_FILE_NEW". How can I manually implement this?
(1) What classes should I instance and create?
(2) The steps to do this?
Best regards,

Hi
I don't want to use MDI default "File-New" to instance a Child Window. I want to create Child Window myself. I need to do special processing during "File-New" process.
My question is: How can I implement the "File-New" operation without using MDI defaults? I don't want to use "Sending message "ID_File_New" message to Client window to get a Child Window. What is other way to do it (Instancing a new Child Window)?
Thanks,

Look in your app's BEGIN_MESSAGE_MAP(). See ID_FILE_NEW? Just change the associated handler.

That is what I don't want to do. I want to get rid of "ID_FILE_NEW". But I want to mimic the what "ID_FILE_NEW" does.
Do I need to instance and create "CSplitfrm", "CmyView, and "CMyDoc" class? How can I do it? what is sequence?
Thanks,

Are you talking about the #define directive in afxres.h?

Have you looked at CWinApp::OnFileNew()?

It is so hard to explain what I want to do.
I want to totally forget ID_FILE_NEw. Just like there is no such "ID_FILE_NEW".
But I need to implement the same function (same with ID_FILE_NEW).
I know I have to do something with "CSplitfrm, CMyView, and CMyDoc" and set them up.
I want to know how to set all these up.
Thanks,

Can't you just remove it (New) from the File menu?

Which is why I suggested looking at CWinApp::OnFileNew()

I want to instance CSplitfrm, view and doc classes to implement this new Child window function.
I can not find "CWinApp::OnFileNew()" implementation.
Thanks,

Did you look in appdlg.cpp? It just calls the document manager's OnFileNew() method. Look in docmgr.cpp for that implementation.

It is complicate. Is there an easier way?

OS Windows XP and Vista. I would like to work with virtual port USB of the printer through CreateFile, ReadFile, WriteFile (for data transfer in the printer to give the command on the print, to clear the printer buffer, to receive its status, to give Printer Page Description and Markup Languages commands, etc.). For me virtual printer port HP LaserJet 1020 in system is designated as USB001. I tried to use the port name in CreateFile (\. \\USB001), it has turned out nothing. Prompt how to work, please, with the virtual printer port. In the Internet has found nothing, only concerning virtual COM ports. Then it would be desirable to understand with virtual port of the scanner.

No, you don't open a USB port directly. What you will need to do is get a handle to the driver for that device. So, you have to know the driver symbolic name and use this one instead.
But, what are you trying to achieve exactly ? Because if you need to print something, there's probably a much better way to do that than to access the printer driver directly...

And how it is possible to define symbolic link of necessary driver USB of the printer? And how it is possible to access the printer driver directly? Me these two ways interest.

Hi,
How can i populate system font names in combobox...
|
|
|
|
|

if possible please let me know how can i use in MFC dialog based project ..as im anew bie..

MFC does not have any special functions for this purpose. You can use this, I suppose:
int CALLBACK EnumFontFamExProc(
ENUMLOGFONTEX *lpelfe,
NEWTEXTMETRICEX *lpntme,
DWORD FontType,
LPARAM lParam
)
{
OutputDebugString(lpelfe->elfFullName);
return true;
}
CTestDlg::OnOK()
{
LOGFONT logFont;
logFont.lfCharSet = 0;
_tcscpy(logFont.lfFaceName, _T("\0"));
logFont.lfPitchAndFamily = 0;
EnumFontFamiliesEx(*GetDC(), &logFont, (FONTENUMPROC)EnumFontFamExProc, 0, 0);
}
Watch your debugger output window to see the results printed into it from the callback function.

Oh great, now he's gonna ask how to take the output from the debugger window and add it to a combobox.
