I have two files. For ex: The column1(Name of the column is time) in file1 has the folowing data:10,11,12,13,14,15,17
Column1 in file2 has the following: 10,11,13,14,15,16,17.
I need synchronize both the time columns so that they have equal times. Note:16 is missing in file1.
Just ignore the column which is missing in any file and proceed to the others
How can i handle this?

Is this what you have, with file1 on the left and file2 on the right:
time time
10 10
11 11
12 13
13 14
14 15
15 16
17 17 Now, what is the output supposed to look like?

output should look like
time
10
11
13
14
15
17

I've no idea. Both of your input files had seven items each, yet your output only has six items. What happened to 12 and 16?

My output should have only the common items in both the files. Ignore the element which is not present in both the files

Ahhh, that is not the same thing as synchronizing. The first thing to do, as I already mentioned, is merge the two files together, thus producing:
10
10
11
11
12
13
13
14
14
15
15
16
17
17
Then you'll want to remove unique items, and then all but one of multiple items.

Dear all;
I am having this weird problem where I am drawing ellipses but they disppear if i resize the dialog box or move the mouse over the shapes.
I know that this problem is related to OnPaint(). Now that i have tried to call Invalidate() and UpdateWindow() after the drawings, I get a blank screen with no drawings. And because the shapes are only drawn whenever I press a specific button, I kind of see the drawings but they quickly disappear.
Here is some code to give u insights:
int CTestDlg::buttonClicked(void)
{
CClientDC dc(this);
drawShapes(dc);
drawings = TRUE;
Invalidate(TRUE);
//UpdateWindow();
}
void CTestDlg::drawShapes(CDC& cd)
{
for(int index = 0; index < 20, index ++ ){
xCentre = getRandom(0, 1000);
yCentre = getRandom(0, 700);
cd.Ellipse(xCentre + 20, yCentre + 17, xCentre - 20, yCentre - 17);
cd.TextOut(xCentre -10, yCentre-10, "A test");
}
// getRandom () is a method which returns a random number
// that is greater than 0 and smaller than 1000 for x and 700 for y
}
void CTestDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, reinterpret_cast<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);
if(drawings == TRUE){
drawShapes(dc);
}
}
else
{
CDialog::OnPaint();
}
}
Now can someone please tell me whats going wrong with my application ??
Thank you

Tr explicitly setting the pen and brush attributes of the DC - you don't seem to be doing that here and that might be part of the problem. Also try eliminating the "if(drawings == TRUE)" bit just to ensure the function is indeed getting called.

thanx for replying;
Actually, the pen of the dc is already set up, i have just not included it in the my previous posting.
I am sure the drawings are painted because i can see them for a while and then they disappear
Now i tried getting rid of "if(drawings == TRUE)". And it is still not working 
any more suggestions

Drawing directly on a dialog box is usually never a good idea.

Put some other control (e.g., static) on the dialog and draw on it instead.

I totally agree with you David.
Now I have added an ActiveX Control (Microsoft Web Browser). And I am trying to draw on it but the shapes still disappear.

There's nothing wrong with drawing directly on a dialog box - I do it all the time. Why do you think it isn't a good idea?

Why do you think a dialog box is provided. It acts as a container for other controls.
Besides it is always messy to do drawing directly on a dialog box. As David said drawing on static is much better. As you said nothing is wrong with it but is bad and messy. Besides when you draw on a static it is much easier to maintain the picture.

The problem with drawing directly on the dialog is that anything at all could make the
image go away (e.g., an email alert popping up over it). Another problem with is that the dialog thinks it controls the background and painting of the dialog; you are asking for trouble by trying to override this. For someone who understands all of the ramifications of doing this, you can do all the right workarounds. But it still seems risky to draw/paint directly on a dialog.

This isn't the case. Dialogs recieve WM_PAINT messages just like any other window when their client area has become invalid. If you put your painting code in the WM_PAINT handler (just as you would for any other window) every things works fine and as expected.
I do understand the ramifications - there are none. I do accept the argument that in most cases it is probably cleaner to do the drawing in a control. That said, for doing things like putting a background on a dialog putting the code in the WM_PAINT handler is the way to go.

Now i have partially solved the problem. what i did was removing:
if(drawings == TRUE){
drawShapes(dc);
}
from the if clause and including in the else clause.
Now i can see the drawings. my only problem is that the drawings disappear if the dialog box is minimized or if another window is overlaid on top of the it.
Any suggestions are very welcome.
void CTestDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, reinterpret_cast(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(drawings == TRUE){
drawShapes(dc);
}
CDialog::OnPaint();
}
}

Well I am not calling OnPaint() at all. On the contrary, OnPaint() calls the method which does the drawings for me. But these drawings disappear after minimizing or ovelaying the dialog box.

Hello.
Can any one help. I am writting a application which has a dialog which is used to display a database. I have derived the dialog from the from the base class
containing the data. I can access the data as exspected. The problem is I need to call the dialog from the base class. Is this possible using this method.
Or do I have setup a pointer to the dialog in the base class and copy all the data to dialog befor I call it as I have done in the past.
Thanks for any help
