Printing in Windows CE, 2.11

27-Feb-03 22:58

The problem with CE is that it will not support printing as we know it on the desktop. In another post, Daniel S talks about sending AT commands via IR to the printer. This may be one solution. Another one, might be using a third-party software. Check HP[^], they have a free printing tool for iPAQs.

Hi there,

I'm working on custom designed hardware (a measuring instrument) with a printer attached to the parallel port. (Windows CE v. 2.11)

When I start printing but the printer is out of paper or off line, the system generates an error message that allows me to press 'Retry' or 'Cancel'.

If I correct the problem and press 'Retry' everything works fine, but if I press 'Cancel' the instrument is no longer able to print until after a reboot.

I can see that EndPage returns a negative value but I can't find a way to handle it.
I have tried to Detach, CreateDC and Attach again but it doesn't help.

Any help will be appreciated

Thanks in advance,
Jørgen

Hi,

Do you have any sample application for accessing the PRINTER from eVC++ program.?

If so please let me know in detail.

Thanks,
siva

Hi Siva,

Basically the access to the printer in CE is the same as in Windows. You can find examples in "Programming Windows" by Charles Petzold, ISBN 1-57231-995-X and/or in "Programming Windows with MFC" by Jeff Prosise, ISBN 1-57231-695-0.

The procedure is almost like:

StartDoc()
StartPage()
.. Do your printing
EndPage()
EndDoc()

An example can be found in the online help in VCC. Search on StartPage

The problem is that these functions apparently don't return an error code on failure as they probably do in Windows? If they do - I can't see them?

If that won't help you, let me know what exactly you do need?

Regards,
Jørgen

Hi Jørgen,

Thank you !

Yeah it seems working !

I have to find another solution..that Daniel S talks about sending AT commands via IR to the printer.I am in a position to figure out all the posiblities to talk with printer and FAX.

If you have any ideas/suggestion please let me know in detail.

Shall certainly revert back to you if any need arises..

Thanks

Why dll can't be loaded

Hi everyone:
This actually my first post and hope to be part of the group... Smile | :)

. I have created an updated 2002 .dll using evc++ and placed it in the root of 2002 ppc. for some reason the system doesn't recognize it. When I try the old one, it works. Any help regarding that? Thanks a lot.

Re: Why dll can't be loaded

I think the system will look first on the \Windows directory. Have you tried to put it there?

Thanks a lot Joao, Yeah I did. and also I figured out the problem. it was the 'outputfile' in the project settings. before, I put it for 'x86debug' while it needed 'ARM debug'.
Tell the truth, I don't know what the difference is...!! I would like to know though. I think it depends on the cpu type of the deveice. However, if that's corrrect, how would we know which for which. JUST A FOLLOW UP THOUGHT AFTER THE BIG HEADACH I GOT FROM THIS TINY DIFFERENT SETTING.

Thanks again for your answer.

You are right about the CPU type. As a matter of fact, you can produce executables for ARM (StrongARM) and the emulator. When you choose the emulator on your project setting, all the compiler's output (.obj, .dll, .exe) goes to the x86debug or x86release (or whatever they are named in your setup). Before generating any output, make sure you have selected the correct target. Wink | ;)

Don't worry too much about this mistake: from my experience everybody does that, especially when targetting multiple platforms, or when transitioning from the debug to the shipping version of the product (it happended to me just yesterday).

Pocket PC Emulator for Win98

I am still using Windows 98. I know that eVC++ will work with Windows 98. Is the an emulator that will work?

Thanks

Heed these words of caution, from someone already charred by tough experience: don't think about it! The emulator is not very stable in Windows 2000, so don't expect it to work on the nimble 98... My experience with the emulator on an updated W2K is one of sudden and unexpected reboots, not even blue screens!
Beware of the wild emulator!

Hi out there,
I'm looking for a way to create a transparent CBrush under WinCE so I can draw a polygon filled with lines. The background of the polygon have to be visible. I tried some things but nothing I've tried had a transparent background.

Thanx for help

What you need is a null brush. Use this:

LOGBRUSH	logBrush;
CBrush		nullBrush;
CBrush*		pOldBrush;

logBrush.lbStyle = BS_NULL;
if(nullBrush.CreateBrushIndirect(&logBrush))
{
	pOldBrush = dc.SelectObject(&nullBrush);
	//
	// Do your drawing here
	//
	dc.SelectObject(pOldBrush);
}

Enjoy!

Isn't this a polygon with no filling?? I need somthimg like:

+-----------------+
|/////////////////|
|/////////////////|
|/////////////////|
+-----------------+

The square is the polygon and the lines are the fillings (my english isn't the best)

João Paulo Figueira24-Feb-03 4:24

24-Feb-03 4:24

Sorry!

I think I did not understand your question. Is that a hatched brush? Maybe you need CBrush::CreateDIBPatternBrush. Take a look in the documentation, they have a sample (I've never used it...)

\SOLMAN24-Feb-03 22:57

All right. Let me tell you what tried so far.

I want to draw a bitmap on the screen of the device and mark an area in the bitmap. Let's say the user loads an image with a building in the front and some surrounding things. And now I draw a polygon with the shape of the building. But I like the building to stay visible. I thought of a polygon with a transparent hatched filling. In this way the area is marked but I can still see the background.

I looked in the MS help for the LOGBRUSH structure. They write of many brush styles. e.g. BS_HATCHED but when I use this define the error message "error C2065: 'BS_HATCHED' : undeclared identifier" is displayed while compiling. So I looked into WINGDI.h and found only the following brush styles

#define BS_SOLID 0
#define BS_NULL 1
#define BS_HOLLOW BS_NULL
#define BS_DIBPATTERNPT 6

The only way to create a transparent hatched brush is to work with BS_DIBPATTERNPT but there is the next problem. How can I create a transparent DIB. I'm relativly new to Windows progamming.
