dev-cpp-users Mailing List for Dev-C++

Ah, I don't think you really read the information in the received mail.

It wasn't to this address that you was supposed to send your request.

I don't have the exact name infront of me, but it was something like

Hello,

We are in a real need of contributors to write the main Dev-C++ help file and 
tutorial.
I believe the help file could be really more effective and complete if some 
experienced Dev-C++ users contributes to writing sections for it, in 
conjunction with Dev-C++ developers.
If you think you can help us on this task, please contact me at 
ha...@bl...

Having a good help file and tutorial is VERY important to this project, so i 
hope some people will volunteer for helping in achieving this task.

Greetings :)

Why not use a template class for the stacks, or at least use same data
type for normal and temporary storage. That would halve the amount of
code.

Second. Constants MAX and maximum are not exactly a premium choice of
variable names. Every thought of MAX_GARAGE_SIZE or something a bit more
descriptive.

Third. For school work, don't you have any school pals to discussion your
home assignments with?

thanks a lot, i'll try it in a few minutes...

got one more question to ask:

i wrote a program using a few stacks, i compiled it and it seems to be working... however, it doesn't do what i intend to do... in the program, there are two stacks called garage1 and garage2 and there's another stack called temporary which i use to hold the popped elements values. but i strangely can't pop the value i'm looking for, only the last element is popped... the code is huge,i'll mark the part which doesn't work and i'll be glad if anyone would look at it and tell me where i'm going wrong...

kind regards...

But most proably that wasn't the intention.

The fact that both array and string was sized with max must mean
something... in this case a failed attempt at space for the characters. By
mistake, the declaration instead created a number of pointers.

char *ptr;
char string[max];

ptr = new char[max];
strncpy(ptr,string,max);
ptr[max-1] = '\0';

or instead
string[max-1] = '\0';
ptr = strdup(string);

Here, you've just declared an array of pointers. You haven't actually
allocated memory, so the pointers are not valid. You need to new[] it, like
so.

    array[0] = new char[max];

and so on.

Try using UPX, an executable compressor. It should be available at
http://www.upx.org/. Otherwise, search on google.

.lib files are only available on VC++. In Dev (MingW (GCC))), libraries are
named as lib*.a (example, libwsock32.a). To use it in your program, simply
add -lwsock32 to your command-line (under Project > Project Options >
General > Linker Options/Optional Libs or Object Files).

All the libraries available can be checked under the dev/lib folder.

As i have said a few days ago, Longhorn will provide only a managed API
(.NET). Here is some more info from a non-programming newsletter:
=20
=20
- New applications and activity centers based on Longhorn's Avalon
API, which appears to be an XML-based successor to the Win32 API that
current Windows applications use. An example of this new type of
application is Display Properties, which presents a vastly different
UI from today's simple dialog boxes. In the Longhorn alpha screenshots
I've seen, Display Properties is a single-window, task-based
application that's similar to XP's User Accounts application. Another
example of this type of application is My Hardware, which features a
collapsible and graphic view of your PC's hardware divided into
categories such as Audio Devices and Input Devices.
