Need some help with fonts and printing
Hello...I need your help, again.
my printing will crash...I have enclosed the complete call stack.
The user clicks on this button
OnBnClickedButton_Drucken(
and I am calling Drucken_weiss() to start printing.
Can you help me to find out what the error means.
500 points.
Best regards,

Hi Zoppo, your are right.
I changed that.

I even erased all font and all printing in OnPrint(CDC* pDC, CPrintInfo* pInfo)
so I only get a white paper....now it stop again here:

Hm - hard to say, that's a lot of code. Could you tell where (in which function/line) in your code the crash happens?
BTW: I think the code as it is above (including the modification from my previous comment) will crash when the printing functionality is called more than once within the lifetime of the dialog since with 'OnEndPrinting' the font is deleted but not set to NULL so the 'OnBeginPrinting' won't create a new CFont instance, instead it uses the now invalid pointer. Change 'OnEndPrinting' to look like this:
void CAuftragsHistory_Liefersch
{
delete m_fontUeberschrift;
m_fontUeberschrift = NULL;
}

you should differ between a crash like the one you had when using the pointer m_fontUeberschrift without doing a 'new CFont' before, and an ASSERT in one of windows functions.
the assertion in Attach function only happens when you create the same font a multiple time. in my opinion you should it create only once and never delete the pointer and never delete the object (resource) before destructing the view.
Sara

Sara
the exception you had is a crash and most probably a pointer error. if using member pointers you always need to initialize them with NULL in the constructor. also any local pointer should be initialized. and whenever you make a delete, initialize the pointer to NULL again. that is a must for member pointers.

Then the debugger should jump to the place in your code which leads to the crash ... please post this function and add a hint where exactly the debugger jumped to.

Hm - that's not good - are you sure the debugger hasn't accidentally switched to another thread? Open threads-window (Debug->Windows->Threads) and check that the 'Main Thread' is the current thread.
Without knowing which function really leads to the stack it's quite difficult - IMO you first should try to step through your code with the debugger to find if your code is crashing anywhere or if the crash happens after your code has run completeley. In the latter case it may be that something in your code somehow disturb something which later on leads to a crash.

it is a com error when accessing the database in function:
Stockbruegger.exe!ADOCG::R
it looks like as you did get an error when connecting to db or loading a recordset but ignored the error and tried to move within the recordset (== result of your query) nevertheless.
can you post the source where you access the database?

Sara
when you suddenly encounter strange errors which occur only sometimes and at different locations, it mostly is cause you worked on corrupted memory somehow. such corruption often happened when using uninitialized pointers or use pointers after delete or access arrays beyond array bounds.
so it is important to initialize each pointer (array) you were using. always allocate memory to a pointer with new before use but also check that it is NULL before assigning a new pointer value. after delete, set the pointer to NULL such that you directly see when your code was using the pointer again.

Sara
when the exception code is 0xc00000005 access violation, it is for 99 percent of all cases a pointer error, such that using a NULL pointer or pointer after delete.
unfortunately the default of exception handling by the debugger is to first throw the exception and hope it will be caught by a try-catch-block somewhere. if there is no such handling the debugger finally breaks in some kernel function. for debugging purposes it is in my opinion always better when the debugger breaks immediately when an invalid pointer was detected. you can force the debugger to do so by going to menu Debug - Exceptions ... - Win32 Exceptions (your local version of visual studio should have Debug - Ausnahmen ... - Win32 Exceptions) and check the box right of c000005 - Access violation. that will cause the debugger to break earlier next time when the exception happened such that the call stack might show the code where the error occured.
same you could do for the com error which is in section C++ Exceptions though i think the com error wasn't the reason for the crash but happened only because the memory already was corrupted.

Where come the error from?
The crash only happens after printing....even a white page....
So is the pointer error etc. only from the printing code? Or could that be that only after my printing code
the program crash down even the pointer error comes from any other places in my code?
I did printing before like this (with a Dialogbox) and so far I had no error like this
Could that be that this comes from GetPrinterDevice?

in win32-exceptions you need to select the 0xc000005 access violation before checking the radio box "wenn die Asunahme ausgeloest wird ... In den Debugger springen".
please post your current code regarding printing.

This is a printing with Dialogbox from a other dialog with no error....but I would like to print without a printerdialog box and to print 3 copies = 3 tray white red green.....so I guess I have to use GetPrinterDevice

Hm - in the screenshot with the threads you can see the function where it happens (CLieferscheine_Dialog::On
In the last code you posted you again have the 'GlobalUnlock(dev);' in the wrong place before accessing 'dev' members.

I guess this is important!!!!!!!
To all, one thing I found out :From OnBnClickedButton_Drucken(
To start the printing
When I put a breakbpoint to the Sleep(1000); behind Drucken_weiss();
And the crash happened it breaks somewhere in Drucken_weiss(); because there is not stop at my breakpoint
I put a breakpoint here: GlobalFree(dlgPrint.m_pd.h
And it stops here after that it breaks and goes not back to OnBnClickedButton_Drucken(

ok, that's fine - let's hope :o)
i think we are back at the point where you would need to generally overwork the printing concept. your Drucken_weiss function doesn't fit to the mfc way of printing.
as told in a previous question mfc doesn't do the whole printing in one handler function what would freeze the screen while printing cause no more messages could be processed. instead you only give an impact for printing and the mfc framework would call your printing functions like OnPreparePrinting, OnBeginPrinting, OnPrint, OnEndPrinting. for example the framework would call the OnPrint for each page separatly what would give the program a chance to process other messages between the different calls such that the program keeps responsive.
the Drucken_weiss function calls the OnBeginPrinting and the OnPrint itself, what could lead to unexpected behavior and also could be responsible for the crash (though i can't spot the wrong statement which actually causes the problems).
some of your code is indeed strange because of the wrong architecture. for example the members m_hDevMode and m_hDevNames which your current code actually doesn't need. you need members if you have to save variables beyond on single call of a member function. that would be if mfc calls OnPreparePrinting (where you should instantiate the printer device) and then you would need that device in the other OnPrint... functions.
Or the calls of StartDoc and EndDoc. those were supposed to start and end the printing process controlled by the mfc framework. in your current code those calls only could make things worse cause they would start and end functionality that not really was required as you do control the printing yourself.
Did you try to debug your code as suggested? aside of the architecture thing i am still thinking that your code uses a wrong pointer somehow and debugging is the way to find those errors.

it is not so difficult. you normally would use a sample project from mfc samples and copy paste the functions. then replace the individual code as retrieving the data or print all three copies.
the main problem with your current code is that it calls framework functions whitout the right context. for example your overload of the OnPreparePrinting of mfc should call DoPreparePrinting and return . then the framework would call OnBeginPrinting.
if you want to go on with your current code i would rename all the printing functions such there is no mismatch. for example call the print function Print and not OnPrint. then drop all calls where you don't have own sourcecode, like the calls to StartDoc and EndDoc and probably the OnBeginPrinting. those function calls caan't help you with your current approach but only make things worse. forget all the member variables which only make sense if the printing was done with multiple calls from framework.

i also would make the m_hDevMode and m_hDevNames local variables and pass them to On_My_Print as arguments. the code looks better though i would assume you still didn't get an output?

....Sara....you still didn't get an output? yes... will not work
do you write any data in the On_My_Print to the dc (device context) of the printer?
note, the idea behind printing in mfc is to exchange screen dc with printer dc such that anything you see on screen in your view now is put to paper.
is that what you want or do you have a printer output that is different from the view contents?

I don´t understand your question.
I will later print a delivery paper "Lieferschein"....that is displayed on a Listenelement ....I will go through every row and print a delievery paper
What is about the HANDLES they are increasing 2 per click when I print...is this good or bad?

handles are pointers to windows resources (where there are pretty much cause you need at least one handle for any windows object, such as windows, controls, bitmaps, files, fonts, ..., ).
as far as i know windows tries to create new handle numbers as long as possible before it reuses old freed handles. that way an invalid use of a freed handle can be detected rather than a wrong one be used.
so your observation seems ok for me.

Thank you all for your great help...untill now I had no crash
I guess the the 'GlobalFree' calls to the end of the function to ensure they are cleaned up correctly. was the trick
Thank you very much.
Have a great weekend.

you simply forgot to create the CFont instance - add the bold line from below:
void CAuftragsHistory_Liefersch
{
//Druckbereich in 0,1mm
pDC->SetMapMode(MM_LOMETRI
//------------------------
pInfo->SetMaxPage(1);
//------------------------
//--------------- Neue Schrift erstellen ------------------
if(m_fontUeberschrift==NUL
{
m_fontUeberschrift = new CFont;
m_fontUeberschrift->Create
0,
0,
0,
600,
0,
0,
0,
DEFAULT_CHARSET,
OUT_CHARACTER_PRECIS,
CLIP_CHARACTER_PRECIS,
DEFAULT_QUALITY,
DEFAULT_PITCH|FF_DONTCARE,
"Arial");
}
//------------------------
}
Hope that helps,
