Hi,
a little example
PRINTDLG pd;
DOCINFO di;
int iError;
float fx, fy;
float fPixXWnd, fPixYWnd, fPixXPrint, fPixYPrint;
float fScaleX, fScaleY;
HDC ScreenHdc;
// Initialize the PRINTDLG structure.
memset(&pd, 0, sizeof(PRINTDLG));
pd.lStructSize = sizeof(PRINTDLG);
pd.lpfnPrintHook = NULL;
pd.lpfnSetupHook = NULL;
pd.Flags = /*PD_RETURNDEFAULT |*/ PD_RETURNDC;
//open the Printdialog and get a HDC for the printer
if(PrintDlg(&pd))
{
memset( &di, 0, sizeof(DOCINFO) );
di.cbSize = sizeof(DOCINFO);
di.lpszDocName = "DocName";
di.lpszOutput = (LPTSTR) NULL;
// Begin a print job by calling the StartDoc function.
iError = StartDoc(pd.hDC, &di);
if (iError == SP_ERROR)
{
ASSERT(0);
}
// Inform the driver that the application is about to begin sending data.
iError = StartPage(pd.hDC);
if (iError <= 0)
{
ASSERT(0);
}
//Get the Screen-resolution(1)
ScreenHdc = ::GetDC(NULL);
fPixXWnd = ::GetDeviceCaps(ScreenHdc, LOGPIXELSX);
fPixYWnd = ::GetDeviceCaps(ScreenHdc, LOGPIXELSY);
::ReleaseDC(NULL, ScreenHdc);
//...or get the Screen-resolution(2), not tested
fPixXWnd = ::GetSystemMetrics(SM_CXFULLSCREEN);
fPixYWnd = ::GetSystemMetrics(SM_CYFULLSCREEN);
//Get the Printer-resolution
fPixXPrint = (float)::GetDeviceCaps(pd.hDC, LOGPIXELSX);
fPixYPrint = (float)::GetDeviceCaps(pd.hDC, LOGPIXELSY);
//the alignment for your window-coordinate
fScaleX = fPixXPrint / fPixXWnd;
fScaleY = fPixYPrint / fPixYWnd;
....
e.g. you draw your Bitmap to your view with
StretchBlt(hdcWnd, 10, 10, 100, 100, hdcBmp, 0, 0, 50, 50, SRCCOPY);
now write the following for your Printer
StretchBlt(hdcPrint, 10*fScaleX, 10*fScaleY, 100*fScaleX, 100*fScaleY, hdcBmp, 0, 0, 50, 50, SRCCOPY);
HTH

Hi !
I posted a question yesterday about printing a postscript file in C++. I still need more informations about this. How can I, in C++ : open the printer device, write the file to the open handle, and close the printer device ?
Thank you for your help !

Off the top of my head:
OpenPrinter
StartDoc
WritePrinter
EndDoc
ClosePrinter
if you need further advise, let me know. I've done it in one of my projects.

Thank you for your answer. But I guess you are mentionning MFC functions, right ? I was trying to do it in standard C++ (I didnt mention it clearly in my question).
Thank you for your help anyway,
Jerome

|

|

Those are standard Win32 functions, no MFC needed. Did you try looking them up in MSDN?
Joel Lucsy

Actually, my application has to be crossplatform, so I'm not allowed to use any Win32 functions. This is why I wanted to do it using standard C++ !
Jerome

Ah, crossplatform, that is an entirely different matter. Since everything is a file under *nix you may be able to use straight file operations as long as you know how the printer is connected. Note, however, that Win32 and *nix completely differ on how printers are handled, you will have to right different code for each.
For *nix, look for the CUPS package. This is the only thing I know of that may make things easier for that platform.

 Hi All gurus,
I have a small problem regarding windows startup time..I have to add an application at windows startup..I have found many things on that and I have finished this part..but the real problem occurs when I restart or logoff..I want my application to be the first one to load..after necessary windows..programs..so that user is not able to access anything..before startup..and must see my application first..can anyone help me out..I know something can be done..Any help or pointers are highly appreciated..
Thanks a lot in advance,

Hi Himanshu
I know 2 ways:
- move your program (link) to the autostart folder
- write your program as service and start the service always -> systemsettings (I think the better way)
Regards
Frank

There is no way, short of replacing system files, to guarantee that your application will be the first to start. Items in the startup folder are loaded after all services have been loaded. Even if it were a service, you could only guarantee that it start AFTER another application, but never before.

how to create text editor into single dialog/mfc???? (like notepad)

You can run the MFC application wizard to build an SDI application, but on the very last step, select CEditView as the base class. Compile the program and you will have a text editor without writing a single line of code.
ariez wrote:

You can run notepad from your program by using ShellExecute(). Check MSDN on how to use that function.

Check out the Wordpad example on MSDN.

Hi,
How to use VC++ to trigger a list box's onChange event for a Select object in a html page.
I use CHtmlView, I can get the Interface of the listbox. I also use put_selectedIndex to chance the select item.
Thanks a lot!!

Wow! I looked at them but I didn't really bother reading the info, so my suggestion was to use MoveWindow. Would that work?

No. The sizes are cached in the CSplitterWnd class, so bypassing them would produce errors later on.

Thank you! I'd better delete my reply then.

But it seems that these function only works for the first row.
when I try CSplitterWnd::SetRowInfo(0,10,10) , it works well.
but if I try CSplitterWnd::SetRowInfo(1,10,10),nothing happen
Thanks

Did you call RecalcLayout()?
My opinions may have changed, but not the fact that I am right.

I'm a student. I'm learning windows programming. Now I want to write a wordpad in API and without using edit control. I find there are too much things I must deal with. I'm puzzled.
Would you have something like this. Please give me the sample or source code.
Thank you very much.

I have seen a tutorial on how to write a text editor but the whole thing is in Win32 asm. However, the concepts and functions are the same as in API so have a look at this link [^].

I'm not surprised. Why would you consider writing a text editor without using an edit control?

Good point. Although I've done it  . Edit controls and rich edit controls weren't enough for what I needed, so I wrote my own. Works beautifully 
I certainly wouldn't recommend it without a few years Windows programming experience though. It was a substantial project
