When I was in undergraduate school, we did quite a few programs that used stdio as the input, and stdout as the output. We were on a Unix box so piping was a big deal, too. Here are some smaller projects that taught, and at the same time, were easy to implement:
Create a file with random numbers, one per line. Pipe that file through an averager, and a sorter (not the one that comes with the OS).
A grading program. Each line of the file should contain the student's name, followed by 0 or more scores, each separated by a vertical bar (or some other easy-to-read character). Pipe that file through a grading program to give each student's average score, and perhaps a letter grade. Sort students by average score.
Roman numeral to arabic converter.
Palindromes
A program that, given a .h or .c file as a starting point, will go through the file and show the #include hierarchy. Each #include encounter will be a "recursive" call. Determine if a circular dependency exists.
A program that will determine if a pattern matches an input string.
A program that will determine if a number is prime.
These are just some off the top of my head.

Is it possible to create a class with template parameters that is derived from a CView and then dynamically create it in an MDI/SDI framework? If so, how would one go about doing this?
Thanks!

this is a two-part question. First, I'd like to know how I can allow the user to drop down the combobox's list without being able to select anything (because they're viewing a record and shouldn't be allowed to actually change the selection while in browse mode and I don't want the combo disabled). The second question is what function should I override to stop the user from closing the CFormView screen if they're in edit mode? I've tried the WM_DESTROY and the WM_CLOSE, but they're still able to close the form. Any help is appreciated. Thanks in advance.

Having a screen where some of the controls are enabled, other controls are disabled, and none of them are updateable, is a bit confusing. The selection in the combobox should be that of the current record, and the combobox should be disabled.

What if someone got into edit mode but changed their mind?

Okay, I think you're right about the combobox being disabled, but I just hate the way it looks when it's disabled. Is there any way to have it disabled but not have that funky color?
With most of the projects I've done for my company (mostly in VB), it has usually been policy to not let a user exit a screen while in 'NEW' or 'EDIT' mode. If they're in either one of these modes, they have to click 'CANCEL' before they can exit the app. This is just a small in-house program I'm writing, but I was trying to stay consistent with what we've been doing.
Thanks for all your help!!
BTW, are there any free online tests you know of that I could use to test my C++ knowledge? I'm the only one at my company who knows any C++, and I'm self-taught (besides what help programmers like yourself have given me the past few months).

I'm not sure to which color you are referring, but disabled controls on my machine are gray. Maybe it's my color scheme.

Understood. When in New or Edit mode, does a modal dialog have focus, with the application sitting in the back? If so, how does one go about closing down the application without first dismissing the dialog?

You could try brainbench.com[^]. I've taken one test. They last about 45 minutes.

I have a problem when starting any application from my VC++IDE (running or steppping), a 30 seconds delay occurs before the program starts.
Do you have any idea ? (this is not a application defined delay )
Tx for any help.

If it is a large project with lots of files, the IDE is most likely going out and checking dependencies. What keystrokes/menu are you using to start the application?

If ur project contains more files then usaually ur workspace will be very slow
After you open ur project, close all the files, and kept open only the required file which makes it faster.

My current project has nearly 450 files. The IDE is fine except for the very first compile. It is at this time that a dependency check is done (and cached). All subsequent compiles behave just like any of my smaller projects.

Guys, the problem is the same with any project, even with a "hello world" with just one source file. Just typing F10/F5 after compile\link and the delay appear 
Tx anyway.

Hmmm, there is the remote possibility that the computer's AV software is getting in the way. If no AV software is installed, I'm out of guesses.

I have some experience programming in C# .NET but am new to C++. Could somebody please tell me what the difference between "->" and "." are in C++, which is to say:
when is it appropriate to use
someclass.whatever
and when is it correct to use
someclass->whatever.
Thanks!

Nevermind, I found it in the documentation. Thanks anyway!

The "." operator is used to directly access the object's members.

-> dereferences a class object pointer.
SomeClass
{
public :
int a;
};
So if you have SomeClass *oSomeClass = new oSomeClass();
Accessing member variable a is done by first dereferencing the pointer and using the '.'operator: (*oSomeClass).a = 5; which is equivalent to the statement oSomeClass->a = 5;

In VC6 when creating a CFormView-based app I could still utilize the printing capabilities of the Doc/View architecture. In .Net when I started my app I chose to enable Print/Print Preview, but since I selected CFormView as the base class for my view it told me that I wouldn't be able to have printing functionality. Does anyone know a way around this? Thanks

I've heard CodeProject.com is good for this, but can't say for sure!

Hi,
Sorry if this is off topic. Is there a free windows equivalent of syslog you would recommend, preferably one that also works with linux.
Maybe it doesn't exist but what I'm looking for is a library that will allow me to call a function which will do just the right thing depending on which platform it is running on.
Thanks

Thanks for the link, it is interesting to see alternatives out there.

For a example I want to create a child dynamic ListBox control like ComboLBox.
ComboLBox is a system class and can we use it?
Or another way?
