Request you to please help me get the following date and time format...
2007.11.21 16:36:46.094+00:00
Also how do I get the milliseconds.
Please give a syntax for this.
THANKS

As you can see the format is (2007.11.21 16:36:46.094+00:00)
year 4 digit . month 2 digit . day 2 digit [space one] hour:minute:second.milisecond +/-GTM time (based on London)
if this is a string than you have to get substring of milisecond place
|
|
|
|
|
How do I do that. Can you post the syntax please?
THANKS

what is your variable type?
like char*, CString, LPTSTR or anyting else?

Have you looked at strftime()?

I have a simple application (SDI) where I am drawing almost 200000 points on the view (inserted code to draw point in OnDraw function of view class). It is taking several seconds to draw to points on client area. In mean time if I double clicked on the client area the points are getting drawn again. And if I keep doing the same (double clicking on the client area) points are getting drawn again and again.
Please any one can explain this..?
Thanks in advanced

Hi Sandip,
The think problem is that when you double click on the client area the client is drawing. So when a draw is needed the system calls the onDraw function. that is why the points are getting drawn when you double click on the client area. Have you written any code for handling the dbl click???. try using a thread to plot the points you will get a faster drawing.
thanks

Hi Niteesh,
Thanks for your reply.
I have not written any code dbl click handler.
Thanks

Hi Sandip,
try OnEraseBkGnd on the CView.
thanks

Mouse clicks on a window shouldn't cause a repaint unless you've got code somewhere
causing the window to be invalidated.
How do you know the points are being drawn again? Does the background get "erased"?
You shouldn't be tying up your UI thread for "several seconds".

void CMyView::OnInitialUpdate()<br />
{<br />
CFormView::OnInitialUpdate();<br />
GetParentFrame()->RecalcLayout();<br />
ResizeParentToFit();<br />
<br />
RECT rect;<br />
GetWindowRect(&rect);
}<br />
<br />
<br />
void CMyView::OnBnClickedBtnTest()<br />
{<br />
<br />
RECT rect;<br />
GetWindowRect(&rect);
}<br />
After OnInitialUpdate() until I clicked test button(run OnBnClickedBtnTest() ), nothing to do.

I am not sure but maybe when you get the rectangle in button code, it gives the button's rectange.
so plz check if your button's top is 30. if it is 30 then you need to find a way to get the view's rectangle

Hi,
The MSDN says that
"The GetWindowRect function retrieves the dimensions of the bounding rectangle of the specified window. The dimensions are given in screen coordinates that are relative to the upper-left corner of the screen."
So may be(am not sure) the window is created (0,0) as top left. Then it is moved to new Co Ordinates When it is displayed. that is why you are getting different co ordinates. My suggestion is that no need to bother about this co ordinates u just use rect. top, rect.left etc. so that your drawing or anything will positioned based on the parent window.
thanks

i need to show one triangle in the display area and it is moving forward. so I use loop to draw the same trianle in the new location. but i need to delete the previous triangle while i m drawing the new one in new location.
plese help me to solve this.
|
|
|
|
|
XOR the old triangle bits. it will clear the area.
first XOR the same triangle with the one you want to delete
after that draw a new one
|
|
|
|
|
Are you sure XOR will retain the background if i didn't first draw the triangle in XOR (I draw the triangle in say RED ?)
|
|
|
|
|
if you are using only one layer it won't which is really bad way to do it. Always keep a background layer. After XOR application redraws it immediately and redraws it fast.
|
|
|
|
|
what's that layer means, do you mean layered window, OP is not using that. if you mean fill with background color, then why need XOR simple draw it.
I mean to say XOR approach won't work if you draw the triangle with solid color, or else can you give a sample.
|
|
|
|

still i cant fixt it out. do you guys can make it simpler. with an example of a triangle.
|

post what you have did, we try to correct it.

here is the poriton of the code:
BOOL CUserInterfaceDlg::PlotGraph(CPoint* Points,size_t m_SizeOfArray)
{
int i;
GraphRegion->SelectObject(PenSimulation);
for (i=0;i<m_SizeOfArray;i++)
{
Draw_triangle(&Points[i]);
}
return 0;
}
void CUserInterfaceDlg::Draw_triangle(CPoint* Points)
{
GraphRegion->MoveTo(Points[0].x,Points[0].y);
GraphRegion->LineTo(Points[0].x+10,Points[0].y-10);
GraphRegion->LineTo(Points[0].x-10,Points[0].y-10);
GraphRegion->LineTo(Points[0].x,Points[0].y);
}
but problem is, let sizeofArray is 100 then 100 triangles are generating but i need to show only one tiangle at a time. as when it generates the triangle no. 8 it should not show the previous 7 triangles. how can i solve that.
|

easy to do that is draw the background every time you draw the triangle to erase the previous one, then better one is draw the previous triangle again in background colour to erase.
you may need some delay in between the nth draw, otherwise human cannot see all those plots, if your machine is fast may be user can see only the last draw. Again,
If you are putting delay, your application will not be responsive, so you may use timers or threads to plot.

Are you using Invalidate () before painting the new one???
