Well I have been working on this menu for a while now and so far I have had nothing to show for it, but finally I can present a little proof that I have in fact been doing something. xD

Check it out: Right arrow to increment and left to decrement

It's still really buggy, but Im smoothing out the edges as I post this. hopefully tommorrow I will be able to get out all the bugs. Next I will render an entire Catergory o_O! And finally an entire menu. Once I get all the bugs out I will go about converting it to DirectX once I get my detour down.

It doesn't look like much, but this took well over 200 lines of code and its still very incomplete. Why so much for such a small effect? well the MenuItem is meant to basic building block of the menu. All other classes simply control these items. And this is filled with a lot of extra stuff meant to play a part when menu is in full effect.

EDIT: just fixed bug where it would delete item name.

What do you guys keep packing your stuff with to get these weird Trojan warnings (Virustotal.com).

Lol. I never pack my stuff. If you don't believe me open it up and view the disassembly in Olly or something. Should see some calls to print statements, GetAsyncKeyState, etc. But I only log left, right, up, and down arrow. So you should only see the hexcodes for those numbers passed to the stack. I don't know why it's saying its a trojan... didnt even Virus scan. Maybe it's because it's so small. idk... =/

Lol. I guess your right. Guess my programs got AIDS o_O. Sorry guys now all ur computers got AIDS too.

Doesn't matter to me I was just saying that to get you digress from whatever weird stuff that could ward of newbies from downloading your content.

Nice work Why06 keep doing your great job

**why06** · 03-13-2010

Thanks. Actually I could use a bit of help with one little problem. Ill post some of the source.

Code:

#include <iostream>
#include <sstream>
#include <stdio.h>
#include <windows.h>
using namespace std;

const static int MAX_OPTIONS = 10;

struct Option
{
	bool selected; // for multi option items
	int optmax;
	int optmin;
	char type;
	int optcount;
	string str;
	string strArray[10];
	int i; //0
	float f; //0.0

	Option(char t, int initval = 0, int min = 0, int max = 1)
	{
		optmax = max;
		optmin = min;
		i = initval;
		f = initval;
		optcount = initval;
		type = t;
	}

	void inc()	//opt++;
	{
		switch(type)
		{
		case 'i':	//is int?
			if(i == optmax)break;	//will not increment if option is at lowest value
			i++;
			break;
		case 'f':	//is float?
			if(f == optmax)break;	//will not increment if option is at lowest value
			f++;
			break;
		case 's':	//is string?
			if(optcount == optmax - 1)break;	//will not increment if option is at lowest value
			str = strArray[++optcount];
			break;
		default:
			break;
		}
	}

	void dec()	//opt--;
	{
		switch(type)
		{
		case 'i':	//is int?
			if(i == optmin)break;	//will not decrement if option is at lowest value.
			i--;
			break; 
		case 'f':	//is float?
			if(f == optmin)break;	//will not decrement if option is at lowest value.
			f--;
			break;
		case 's':	//is string?
			if(optcount == optmin)break; //will not decrement if option is at lowest value.
			str = strArray[--optcount];
			break;
		default:
                break;
		}
	}
	string print()
	{
		string s;
		stringstream out(stringstream::in | stringstream::out);
		switch(type)
		{
		case 'i':
             char buf[50];
			 s = itoa(i, buf, 10);
			 break;

		case 'f':
			out << f;
			s = out.str();
			break;

		case 's':
             str = strArray[optcount].c_str();
			return str;
			break;
			
		default:
			return s;
		}
		return s;//redundant? no. ;)
	}

};

int main()
{
    Option** opt;
    opt = new Option*[MAX_OPTIONS];
    for(int i=0; opt[i]; i++)cout<<"element: " <<i << " exists."<<endl;
    system("pause");
    return 0;
}

Compile this and you will see that there are two element is the array named opt, and I have no clue why that is. I'm using Dev-C++ to compile, but I'll try in VS and see if I get the same thing.

Result From Visual Studios:

Code:

element: 0 exists.
element: 1 exists.
element: 2 exists.
element: 3 exists.
element: 4 exists.
element: 5 exists.
element: 6 exists.
element: 7 exists.
element: 8 exists.
element: 9 exists.
element: 10 exists.
element: 11 exists.
element: 12 exists.
element: 13 exists.
Press any key to continue . . .

Result From Dev-C++:

Code:

element: 0 exists.
element: 1 exists.
Press any key to continue . . .

With the same exact code.... Oh lord. Is it to much to as for consistency between different compilers. those elements should be null... >_>. why does it seem like there is something there?

Any ideas? Your guess is as good as mine. =/

What is this suposto be exactly?

Use wxDev-C++ btw. It's an updated project with wxWidgets support (something like that) suppose to allow for GUI code portability across platforms.

Doesn't really matter. It's just a structure. the main method is all that's important... and the results.

Code:

int main()
{
    Option** opt;
    opt = new Option*[MAX_OPTIONS];
    for(int i=0; opt[i]; i++)cout<<"element: " <<i << " exists."<<endl;
    system("pause");
    return 0;
}

@Arhk: didn't know about. thanks 4 the tip.

o___O... goodboy.

Anyway figured out the problem was that under C++ ISO new does not zero the memory region being used for your array... kind of makes me wonder what
's the point of allocating an array of a specific size, but whatever. Anyway my first idea was to use a for loop and zero it all, but I decided to use memset instead. I've been at this for a while now, but more and more I start figuring out how I depended on the compiler in Java to handle bounds checking and garbage collecting. Still not use to specifying so much. Anyway:

Code:

int main()
{
    Option** opt;
	cout<<&opt<<endl;
    opt =(Option**) new Option*[MAX_OPTIONS];
	memset(opt+1, 0, sizeof(Option*)*(MAX_OPTIONS-1));
	cout<<strlen((const char*) opt)/4;
    //NULL all elements. Guess I have to handle this myself. screw u compliler >:|
    for(int i=0; opt[i]; i++)cout<<"element: " <<opt[i] << " exists."<<endl;
    system("pause");
    return 0;
}

that's the fix.

Also found out this neat trick to find the size of any array using strlen(). So pretty neat trick I guess.

**Arhk** · 03-14-2010

I'm pretty sure that you null the array memory in its declaration
int array[n] = 0;
~
but I got that style of instruction from an 80's C book.
