That doesn't make sense: the size of a file depends on how many bytes you write into.

No no I said its on the databases when you set an default site for log and data files but after some times you want to increase size of databse its not for files.
If you tell me what do you want to do and why you want to increase size of file I can help you better.

Press down the 'CTRL' key and then, while still holding the ctrl key down, press the 'A' key.

PJ's answer is 100% right if you are using an application someone wrote (and I wish I'd replied that pithily). Or you could ask on a forum dedicated to ThatAppOverThere(tm). You wouldn't come to this forum asking how to press save in notepad?
If you are writing this application, then you need to look at Accelerators (do a search in your msdn docs)

You should read what Iain wrote. The Ctrl-A combination is not built into the Edit Control.

So call it.

how to call it should i use SendMessage and pass my own created WindowMessage
|
|
|
|
|
If you want to click it yourself without click on the button yes you can use of SendMessage.
|
|
|
|
|
Double click on button on the form.

If you are working with MFC you can just create the function of the OnButtonClick using the Wizard (if you are not so self confident to make it by yourself) and then just call the function where you want, when you want.
For example:
in your view/dialog header
public:
enum { IDD = IDD_MY_VIEW};
CButton m_cbTest;
.
.
afx_msg void OnBTestClick();
DECLARE_MESSAGE_MAP()
and in your code file
void CYourView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
DDX_Control(pDX, IDC_BTEST, m_cbTest);
}
BEGIN_MESSAGE_MAP(CYourView, CFormView)
ON_BN_CLICKED(IDC_BTEST, OnBTestClick)
END_MESSAGE_MAP()
and after...
void CYourView::OnBTestClick()
{
your code...
}
and then you can call the OnBTestClick when you want
Regards.

Hi all,
I'd like to know if it would supose some optimization to use /OPT:WIN98 setting in Visual Studio 2005 / 2008 with XP / Vista as target operating system.
Thanks.

Very less people run Windows 98, so give them a separate build with /OPT:WIN98 linker option.
Otherwise, always build with /OPT:NOWIN98.

Yes I agree, but my question was, if still would be useful to make code 4K aligned? It makes some improvement to run aligned code in XP or Vista? or depends on fat32 / NTFS?
Thanks for replying.

You just lose a few bytes in your executable size, that's it.
|
|
|
|
|
so, there's NO benefit in run time execution?
|
|
|
|
|
I played with this linker option some time ago, I couldn't see any difference in performance. This may be different for your code, just try it.
