Then you ignore the post and move on. A comment to every post, contrary to popular opinion, is not necessary.

The problem was stated with code. That's good enough for, and easily understood by, most.

No, not at all. But then everyone has a right to their own viewpoint. Some folks are capable of learning a great deal by mapping what they know to a new language.

Hello Guys,
I am using a static text control and i want when the user click on that static text control then the user will able to go to that page which i link.How should be possible it? Please give me any suggestion.
Will we able to use any message maps or events with static text control?
Also i did not want a hyperlink by using the sethyperlink function.

Did you can set Notify for static control?

Search CP for "static hyperlink" controls.

CMyListCtrl::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
And the parent window need to handel NM_CLICK from the list ctrl too.
Now only the handler in CMyListCtrl will be executed.
How to let both handlers work?
Thanks.

MFC's global message handler will always use the first handler found. That means you have to forward the message to the parent window yourself.
Don't try it, just do it!

It doesn't work. When I send WM_NOTIFY in the ctrl's notify message handler, it seems that there is a deadlock.
|
|
|
|
|
Just another way, send my msg instead.

I've been doing some profiling and have come across a portion of my code that I suspect can be sped up (although it is already quite simple). I have a loop where I do a calculation. In this form:
for (int i = max; i >= 0; i--)
for (int j = 0; j <= limit; j++)
value = calculation(i,j);
The loop is blazingly fast. I can do about 20,000 iterations in a fraction of a second. Then I added an if-elseblock:
for (int i = max; i >= 0; i--) {
for (int j = 0; j <= limit; j++) {
if (quantity > 0)
value = calculation(i,j);
else
value = 0.0;
}
}
In the above form, the 20,000 iterations can take about a minute. Speed is very important and the simple addition of the if-else brings a huge performance hit - I suspect because the compiler can't optimize the loop. Does anyone see a creative way to remove this if-else block and replace it with something the compiler can optimize? It seems it should be simple, but I can't really think of anything off-hand.

Hi Maxwell, thanks. I should have mentioned the calculation is indexed by the loop. I've been thinking of something like:
#define MAX(x,y) ((x)>(y)) ? (x) : (y)
but then I have to calculate x on each iteration so that isn't an improvement.

if quantity is not i, j dependent then Maxwell suggestion still applies.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Yes, of course! We shouldn't mislead anyone. Good of you to point that out.
|
|
|
|

well... assuming that is not a poor example... if quantity is not based on i,j why is it inside a loop? Since value is assigned not summed or similar, only the last value of the loop is stored. You could count backwards and stoop on the first hit and get the same result.

I want to display a value from the file and display it on the editbox. for example
in the file the time format is something like this
11:06:16:254
now i need to put 11 in one editbox, 06 in the next editbox and so on... that means i will have 4 edit boxes to display the time.
the file format that i have is of .dat extension. i am using mfc for this
please give me some leads.

You have a problem reading from the file or displaying it on the screen?

1) research the MFC library documentation for File I/O. This will provide you with the ability to open the file and read data from it.
2) research the MFC documentation for the class CString. This will provide you with solutions for separating the different parts of the time data.
3) Research the MFC CEdit control. This will lead you solutions for displaying the edit controls and setting the data into them.
4) Thank your instructor for giving you such a simple assignment.
