Operation with virtual port USB of the printer and the scanner

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.

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); //Populate your combo box here
   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.

How to resize the controls on a dialog based on the size of the dialog

I have a dialog based application. The dialog has a list control, few buttons, static text, edit box on it

I should be able to re size the dialog after the application is executing So when I re size the dialog, the controls in the dialog should also get re sized according to the size of the dialog, Can I know how to handle this.

Thanks..

See CResizableDialog[^].

Also, I don't think it is a good idea to resize each and every control. For instance, enlarging something like a checkbox along with the growing size of a dialog doesn't make sense. Things like static text and edit controls can be resized though... The article I pointed you to does pretty much does that and you might want to take a look at the code or use CResizableDialog directly in your project.

Did you read the forum guidelines [^]?
You should be specific, for instance what kind of rotation do you need (arbitrary angle, simply 90 degrees steps,...)? What's your bitmap format? What code did you make?

Is your CPMRU working well? Mine seems broken. Moreover I cannot get a piece of useful info from his posts.

BTW: After 'data mining' we should introduce a new discipline: 'data guessing' (and I suppose we need more 'intelligence' for this 'business').

Hence you need to a function to rotate an image by an arbitrary angle. This is the maximum info you provided so far. I can just give you this link [^]. Good luck.

PRINT PREVIEW ZOOM COMBOBOX

Hi Friends,

I need to show zoom combo box in print preview window like Microsoft power point print preview.

I removed zoom in and zoom out buttons.

I dervied my class i.e.

class CPrintPreviewView : public CPreviewView
{
  void SetScaledSize(UINT nPage);
}

void CPrintPreviewView ::SetScaledSize(UINT nPage)
{
switch(m_nZoomState)
{
case ZOOM_25:
     pRatio->cx = 25
     pRatio->cy  = 100;
break;

case ZOOM_400:
   pRatio->cx = 400
   pRatio>cy  = 100;
break;
}
}

I inserted the zoom combobox and added zoom levels from

25% to 400%, as user selects value in cobmobox, I update zoom ratio and call DoZoom function.

But there is some calculation problem.... ??? I dont know what ??

But if i keep zoom in & zoom out buttons and click zoom out button once
and then use combo , there is no problem.

Everthing is fine.

Can you please provide me some code snippet.

Thanks,
Subhash Madhukar
