Thank you. I tried searching the messageboards before asking, sorry if this question was already answered in another post. The reason I used PeekMessage was mainly because that was how I was taught from all the tutorials I read on the net. Should I just create a timer and render when I recieve WM_TIMER messages instead?

Sorry I have been away for a while; almost any thing using a PeekMessage loop is probably old school. I had to reread the original post and I recommend visiting gaming sights. A WM_TIMER message will work fine (also old school); just make sure you have a flag to tell you when an update is needed. You will normally here the term dirty flag (like a modified flag), which simply means something has changed. So your timer function will check the flag and if nothing has changed then you do nothing, quick and clean. If something has changed then you need to redraw the screen or preferably only the portions that have changed. Given time you will figure it all out, provided no one else is breathing down your neck.

hi,
How can we use AutoLoad() to load a bitmap for the button
Thank you
|
|
|
|
|
From The Docs:
// Initialize the owner-drawn button with the id IDC_MYBUTTON as a bitmap
// button. This code is used in the OnInitDialog handler of my dialog.
//The button property should be set as BS_OWNERDRAW
myButton.AutoLoad(IDC_MYBUTTON, this);
Somethings seem HARD to do, until we know how to do them.

Hi,
Thanks for your reply.
I have taken a button and set the ownerdraw property and mapped it as myButton and used in InitDialog() I wrote :
myButton.AutoLoad(IDC_MYBUTTON, this);
But I am getting an exception in this line Please tell me how to solve it.
And can you tell me a bit more abt AutoLoad() bcoz I didnt understand how the bitmaap is loaded without mentioning the resource id in it.
Thank you.

Hello everyone,
My friend and I are discussing about an interesting question, how to calculate efficiently how many 0s are at the end of N! (1 * 2 * 3 * ... * N-1 * N).
Our algorithm is like this,
1. Use a loop to calculate N!
2. Use a loop to calculate %10 result of N!, then /10 each step
Are there any better solutions?
regards,
George

First this will probably be the end of my contributions to your question.
The answer is none, or as many as you want.
If you do not understand the answer, then I suggest you reword your question.

Hi George,
This is the first time I check my mail since posting, that and I really did not plan on coming back. The number of zeros following any number is none or infinite. The number of zeros displayed is up to the code displaying those numbers, which is limted.

Hi John,
I think to calculate the number of trailing 0s is an algorithm problem, why you say it is a display problem -- we can calculate the number without displaying it, right?

George

Hi George,
I was answering an email when I received your reply. I did not say the number of zeros was a display problem. I said the number of zeros following any number is infinite, which means you can display as many as you want. If you want to run an algorithm to display all the zeros following any number, then go ahead. Just remember that the machine will never stop printing zeros until you stop it or turn it off. It is a matter of how many zeros you want to display. I know there are some functions (algorithms) that will print a ridiculously high number of trailing zeros, but that is the designer’s choice. The normal problem for those using it is to trim all those unnecessary zeros before displaying it to the user. Trailing zeros are not really part of the number as they are a given. If a number has a hundred zeros following it and they end with a 1 then they are not trailing zeros, but any zeros following the 1 are.

Hi John,
I do not want to print the 0s. I want to print the number of 0s. For example, if the input is 5, then output is 1 (5! = 120), if the input is 3, the output is 0 (3! = 6).

George

I apparently do not understand the original question. I am not a mathematician and have forgotten most of my advanced math a long time ago. I thought we where dealing with trailing zeros which is the same in code as it is in mathematics. What you are showing me does not make since to me from a coding point of view. For some reason you have my attention, but to be honest I do not know what you are talking about. If you find an answer and remember me, please do not hesitate to send it to me via codeproject.
Well goodnight now, it is about 8 hours passed my bed time.

Do you want the number of digits of the number of 0's. i.e.
4! = 4x3x2x1 = 24 = 2 digits; but no zeros.
If you want the number of digits use log (base 10). I believe it's called log10.

Hi Steve,
Log10 is not working -- it only checks the length of a digit in base 10 -- not the number of trailing 0s.

I see; you literally want the number of trailing 0's and not the number of digits. It's an interesting question.

Hi Steve,
You are right. If you have any further comments or ideas, please post here. I am happy to discuss with you again.

When i opened my project...the dialog displays as
"Cannot access classview information file.Classview information will not be available".
Wats wrong in my project?
I delete my .clw file and rebuild the project.The same problem exists.

This may some time happen. Either you may be having your project open somewhere else or you are not closing the application properly. Anyways you can try the procedure given below.
Delete the .ncb file that exists in your application.
Go to the Task Manager and close all running instances of MSDEV or .NET
Open Your project with the .dsw or .sln extension.
RebuildAll.
Does this solve your problem. If not you need to create a new workspace and add your existing files to it.
Somethings seem HARD to do, until we know how to do them.

how to convert my program to unicode

Hi !!!
There are few rules:
1. you have to define _UNICODE, if you have precompiled headers file, define this there
2. you have to use _T("some text") macro for strings instead of "some text"
3. you have to use TCHAR instead of char
4. for console input/output you must use wcin , wcout, wcerr instead of cin, cout, cerr
5. you have to use std::string class with TCHAR instead of char
You can do this:
typedef std::basic_string<tchar> string;
I hope I helped you !

I have created a splitter window inside another splitter window.
In the newly created splitter window pane, a tree control is placed.
Upon selecting an item in the tree control, i want third splitter window to get created. But i am not able to get it done.
Before selecting the item:
first pane
---------------------------
tree|
ctrl| second pane
pane|
After selecting the tree item:
first pane
-----------------------------
tree | I-II pane
ctrl |--------------------
pane | II-II pane
Any body plz give me an idea.
Thanks in advance.
