if so, there is no problem, i am sure.
CString can handle much longer than 256.

Do you know approximately how much longer ?
Because this class handles all operations +,-,*,/ and returns the right result . //Only if result (the number) is //less than 1024 digits.

at least 1M, i guess. i used for hundreds of Ks.

According to this[^] thread, a CString can hold up to about 232 characters. I've used it with 64K chunks of text with no problems.

Wrong. CString objects can store up to INT_MAX (2,145,483,647) characters. This is documented in the CString::AllocBuffer() method.

It sounds like you need to take a look at the limits of the algorithm you are using to multiply those numbers. You may be overflowing or something like that.
CString is limited to the maximum positive size that can be stored in a 32-bit integer (minus some overhead).

hiho@ll
i have an app which uses skins
and i want to use a hidden button for a tooltip
but it doesn't show!
the tooltip only shows when the button is visible, but this isn't what i want/need
andybody knows a workaround?
thx@ll

tooltip works with the button's messages of WM_MOUSEMOVE etc.
if the button is invisible, those messages will not be sent to the button, so standard tooltip doesn't work anyway.
you can create ur tooltip for dialog, if mouse moves to the button's position, then show ur tooltip. this is possible only way to do.

There are probably dozens of ways to accomplish this (I do not know them). But what you can possibly do is create an owner drawn button and then make it completly transparent, that way it is still invisable to the eye and yet windows will still consider it visable.
How do you make it transparent? Again there is more than one way! But if you make it an owner drawn button, then you simply do not draw it and say you have. (Simple!)
There are lots of articles at CP on custom controls like buttons, take a look and enjoy!

Probably easier is to use a picture control and define it as a rectangle with etched color.

Question: Are tooltips tied into picture contols (via MFC) or do you have to monitor mouse movement and figure out when to manualy call some tooltips function to show the tip.
If the latter then it probably is not easier. But, like I said, there is no dought that there are multiple way to accomplish the goal.

Thanks in advance.

Hi, I am a TA(Teacher's Assistant) for a computer sciences class and I was wondering if you have any cool programs or segments of codes that I could show the class. Any help would be greatly appreciated.

after reading your other questions, I question the wisdom of the person that put you in your TA position.
look around CodeProject, there are TONS of cool things and samples that people have shared.
but it all depends on the level of the class you are facing; do they know any programming language ? What are their experience ?

actually this is a basic class that I TA for. My teacher has asked me to look for all of the things I have looked for. Everyone in this class is just learning their first language and I have mastered all that is taught in this class, but I live in OREGON!!! We have no funding so I'm probably one of the most able programmers in the school but we don't have enough classes about programming so need all the help I can get so I say again any help will be appreciated, especially cool SIMPLE codes.

Hey it's nice to here someone from back home is trying to share the wealth! This may not be the best place to look for programs for a beggining class, although there are a lot of articles here for begginers. It depends on what level of programs you are looking for: are they just to show what can be done or are they ment to show how to do it? There are articles here that can do both (more or less), but most are for peaple who already now how to program. One place to look for programs, is in archives, like the C/C++ User Journal (formaly C User Journal), they have programs going back for years (since before Windows or even DOS as we know it). Another source is university sights, some universities may even still have a BBS in place. When I started programming, I spent a great deal of time visiting the North Carolina State University (NCSU) BBS.
One more sugestion: Grab a book on computer terms (dictionary) look up the subject of interest and use the information there to determine what keywords to search for, then start googling!
Good Luck and have a great day!

That's like going to a car lot and asking the salesperson if they have any vehicles that could be shown. This whole site is about "cool programs or segments of codes," all of which can be shown to the class.

I would like to know how to make a program that is not opened through Visual Studio but is opened as its own program. So basically I want to make a program to be able to be opened through an icon on my desktop, not through a compiler.

Your request does not quite make sense. For example, "make a program" is vague at best. By using the compiler to create an application, you can then put a shortcut (i.e., icon) on the desktop for that application.

sounds like you just want to build a project rather than just compile it.... what compiler are you using?

If I understand your question you have been simply running your project
from the IDE ( pressing F5 or CTRL-F5 etc. )
When you do this, before the program runs it is first compiled,
and an executable is created ( e.g. yourapplication.exe )
The location of this executable can be found by looking at
Project->Settings on the [Link] tab.
Make sure you have the correct project and build debug or release)
selected in the left pane, and the name and location of the executable
will appear in the "Output file name" edit box ( you can change this )
If the path is a relative path it is relative to the project path
(where your source code is stored)
Using Windows Explorer you can copy (or drag-and-drop) that executable
file onto your desktop (or anywhere else) or simply make a shortcut to
it on your taskbar.
By default it will have the blue MFC icom but you can change that
by editing IDR_MAINFRAME in the 'Icon' resource

Help me out! I would like to know how to make a graphics library/file. If you know how please help.

Like you would any other library! You need to be more specific! Figure out what you want to know, make a list. Search the net for posted articles, then come back with specific questions.

I would like to know if there is a way to store a character in a type int variable. I would still like the variable to be able to store integers, but if a certain charcter is entered I would like the program to do something else.
example:
int number;
cout<<"Enter a number: "; //This is where I would like to enter 'c'
cin>>number;
if(number=='c')
{
...
}
else
{
...
}
can you please help?

if(number=='c')
Which is equivalent to:
if (number == 99)
