you should use 'new' .
i.e: char *time = new char(10);

Just declare the 't' string to have soem data space available.
Do
char time1[32];
instead of
char *time1;
and it will be fine.

Hi,
Since I can't put the initialization of a static data member in the class definition, how can I assign the value of lets's say a document data member to an object's static data member ?
Thx.

You have to do it in the cpp file
class foo
{
static int x;
int doFoo();
};
int foo::x = 12;
int foo::doFoo()
{
...
}

Is static data member accesible
only accessible by scope resolution operator .
say
by "this" pointer .(or pointer to class)

that doesn't mean its accesible only by a "::", but since its accessed directly through a class we need to use ::. its not accessed thru an object.(.) if u do so by an object, it creates new values everytime new objects get instantiated but here ::, its static (same)for all.

When I draw to a dialog window using dc.SetPixel, everything looks great... until another window is moved over the dialog. All graphics are erased. How can I prevent this?
|
|
|
|

you have to do all your drawing in response to a WM_PAINT message, or in MFC-talk, in your window/dialog's OnPaint member. that function is called when your window needs to be repainted, and if you're painting anywhere outside that funciton, your stuff will be overwritten the next time the default drawing stuff gets called.

Thanks. That works pretty good. But I must be doing something else wrong. Below is a snip from a simple dialog program to draw a box when a button is pushed. I put the drawing stuff in the OnPaint. Although it does redraw the box most of the time, when I drag another window over the box slowly, sometimes I get lines where the box was not totally redrawn.
void CBoxDlg::OnPaint()
{
int x, y;
CPaintDC dc(this); // device context for painting
if (IsIconic())
{
SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
if (draw_rectangle == TRUE)
{
for(x=0;x<100;x++)
{
for(y=0;y<100;y++)
{
dc.SetPixel(x,y,RGB(240,0,0));
}
}
}
}
}
void CBoxDlg::OnDrawButton()
{
draw_rectangle = TRUE;
RedrawWindow();
}

i need an example of open dialog box with Source Control button (meaning... open dialog box that allows to open regular files on a client computer and also allows to open files from Source Control (like sourcesafe)).

Hello.
What's the problem?
If you want to know how to mark the end of a data file on tape, the normal way is to write a Tape Mark.
The rule is:
End Of File: A Tape Mark
End Of data on Tape: Two consecutive Tape Marks.
Is that your problem?

Hello.
OK, I get your problem.
But I'm sorry to say I can't help you. I thougt you were using raw tape writes, and had a problem with that.
I've created code to handle all major file systems on magnetic tape, but I haven't used Windows backup tape library.
Again, I'm sorry.

i dont find any reason for this error. my application was working fine. but it started behaving like a b****t. when ever i close it, it throws
"QACD Application has encountered a problem and needs to close. We are sorry for the inconvenience." exception 4 times.
this happens only upon closing the Dialog. what could be the matter?
