The flash memory of the PIC controllers is the program memory where code is stored. You can initialize the variable at compile time and it will be written together with the program code.
To write to the program memory by the running program you need to execute special instructions. For the PIC 32 see section 5. Flash Programming[^ PDF] of the PIC32 Family Reference Manual.
A compiler or assembler may provide functions or macros to perform the writing or compilers may have built-in support for writing. So the answer if the value is written depends on the used compiler. But if the compiler does not support writing to flash memory, you will get an error at compile time.
it really depends on the company/implementation - I doubt there's any 'standard' meaning, eg 'Example', 'Extension' - the only way to know for sure is a side-by-side comparison using [insert name of your favourite diff/compare tool here]
thank you very much. i had to name something where it was in appropriate to overload, and I couldn't think of an appropriate name. i saw something in microsoft's thread or mutex library that used that naming convention. I should have realized Ex meant "extended", duh. Kind regards,
I have an ATL dialog based applications.
I have a custom list control derived from CListCtrl with message map
BEGIN_MESSAGE_MAP( MyListCtrl, CListCtrl )
ON_NOTIFY_REFLECT( NM_CUSTOMDRAW, &MyListCtrl::OnNMCustomDraw )
void MyListCtrl, ::OnNMCustomDraw( NMHDR *pNMHDR, LRESULT *pResult )
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<nmlvcustomdraw*>( pNMHDR);
// Take the default processing
*pResult = CDRF_DODEFAULT;
if( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
*pResult = CDRF_NOTIFYITEMDRAW;
else if( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
int nRow = static_cast<int>(pLVCD->nmcd.dwItemSpec );
if( true == MyArray[nRow].bIsOlder )
pLVCD->clrText = RGB( 128, 128, 128 );
pResult = CDRF_DODEFAULT;
But I am not getting ant reflected message from the parent dialog.
I know that it can be done by using the REFLECT_NOTIFICATIONS() in the parent class. But I read that we have to derive the CListCtrl from CContained window. Is it the right way, if so what are things I have to take care.
Is there any better solution to resolve this issue?
Hello everyone, there is an article in Chinese discussing MS Detours API hooking library and Mhook library. I don't understand how to download the attachment and I can't understand the article. Could anyone who understands Chinese help me out here? Much appreciated in advance!! Please
I'm facing the following strange problem using MFC Grid Control (by Chris Maunder) in my VS2010 MFC application:
I've included the CGridCtrl control in a dialog in order to let the user to edit data. It works fine but sometime when I open the dialog the cells content is not displayed but it's covered by the cell background color.
Unfortunately I can't solve the problem because it only happens randomly. I tried to call Invalidate() to both the CGridCtrl control and the dialog but it doesn't solve.
Normally we would tell you to post this question in the forum at the bottom of the article: MFC Grid control 2.27[^], but I think it is ok for you to post it here as well.
Although Chris is around all the time, he is obviously very busy so there is no guarantee he is able to answer your question.
It is a very old project by now (it is article #8 here on CodeProject!), but I see that Chris did update it not too long ago. In your explanation of the problem, you need to include which version of Windows you are running it on an make sure to mention whether it is 32 or 64 bits.

From things you've said, I think you're talking about printing on paper instead of a screen.
There is indeed a process to follow when doing so, it involves telling the print sub-system that you've printed a page and wish to print another in the same print-job.
You can and should enumerate the available printers in your system and allow the user to choose from them. In this example, I've simply used the printer's name, as seen in Control Panel\Hardware and Sound\Devices and Printers in Win7.
