The ID is defined in resource.h and then passed in by name. This is so there is no double up, where two controls have the same ID.

I want to use in serialize and CArchive for save and load from file
But I don't know how can I check if the loading success ?
Who can help me ?
|
|
|
|
|
Try using...
if(ArchiveObj.isLoading())
{
}
else
{
}
Hope it works...
|
|
|
|

I need to check if the operation of the loading itself is successes or that failed for example in case that the file terminated suddenly.

Sorry, In your if/else bodies you need to check the for the end of the file. Try using a counter, and the CFile::GetLength() if CArchive derives from CFile(I don't rememeber) or if not CFile::GetStatis(/*FileName as param*/) which fills the CFileStatis(The Name may be wrong so check MSDN) obj and the CFileStatis obj will have a length memeber(check MSDN for name). You need to use if statements to test the counter to see if counter is smaller than the file length. When you read the Archive add the amount you just read from the Archive to the counter(this is hard to do and I can explain it here maybe later in this thread if you like).
Hope this helps...

CArchive will throw an exception if it encounters a probloem while loading or saving the file. This includes if it encounters an unexpected end of file.
(code assumes fp is a CFile object already opened.)
try
{
CArchive ar(&fp, CArchive::load);
// serialize objects here
ar.Close();
}
catch(CArchiveException* pArError)
{
// an error occured
pArError->Delete();
}
catch(CException* pError)
{
// an error occured
pError->Delete();
}
catch(...)
{
// an error occured
}

With <'PRE'> and <'/PRE'> without '
Carlos Antollini.

By using the <pre> HTML Tags...
<pre>What you want to be Preformatted.</pre> The <pre> allows you to display a fixed font and more than one space(HTML allow only one space to be displayed outside of <pre>...</pre> ). The yellow is applyed by www.codeproject.com in maybe a stylesheet that replaces the background color of all the <pre>...</pre> it find.

I have an HICON, and need to be copy the contents of it to a HBITMAP.
How could I do this, please?

Call DrawIcon or DrawIconEx for memory device context with HBITMAP selected.

Anyone know how to read bits using a structure?
I used to do it like this using Borland. I need to know how to do it in MFC.
union test
{
int n 1:8;
unsigned char c;
}
This may not be correct syntax its been a while.

This will compile when you remove space between 'n' and '1' and add semicolon after }.

How can I change the colour of the text in a button @ run-time.
I tried to override the onctlcolor method:-
HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_BTN)
{
pDC->SetTextColor(RGB(255,0,0));//set red
return (HBRUSH) m_Brush.GetSafeHandle();
};
return hbr;
}
m_Brush is a member brush & in OnInitDialog method, I create it with a solid brush.
m_Brush.CreateSolidBrush(RGB(129,129,129));
Thanks
Gerry.

I am trying to make the text bold in a CStatic. I wrote the following code, Can anyone see where i am going wrong.
CFont *M_titleFont is a member varible.
Code Snippet, from oninitdialog:
LOGFONT lf;
m_titleFont->GetLogFont(&lf);
lf.lfWeight = 700; //Set Bold
m_titleFont->CreateFontIndirect(&lf);
Cheers
Rich

Oops Missed That Bit Out!
m_titleFont= GetDlgItem(IDC_TITLE)->GetFont();
Thanks Again
Rich

I found I had problems using CreateFontIndirect() with an existing font. But it was easier to create a new font instead.
LOGFONT lf;
m_titleFont->GetLogFont(&lf);
lf.lfWeight = 700; //Set Bold
CFont boldFont;
bolFont.CreateFontIndirect(&lf);
// continue to use boldFont
Hope this helps. =)
