[Glynnder]

TUW, please add me on msn

[the unique warrior]

I have no time ... maybe later.
too busy with gf now :/

[Glynnder]

oh ok lol.

[hallo007]

i overwrited the SDK with the HENSDK

[Glynnder]

u mean overwrote

[hallo007]

yeah;)

[Glynnder]

if there's any good C devs here willing to help me then please add me on MSN- [email protected] much appreciated

[hallo007]

i want help , but i am not good;)

[the unique warrior]

please don't edit the SDK if you don't know how to...
so hallo007 use SE-SDK with the real SDK don't change it!
Thanks,
TUW

[Glynnder]

how do you list a directory in C.
and then how do you kind of use each file.

[SG57]

Word of advice to any that are doing some calculations such as this. Order of Operations is important, if you hadnt already knew.

//simplest parabola
y = -x^2
// when x = 5, it comes out as -25, not 25 as it calculates exponents than multiplication

// simplest parabola
y=(-x)^2
// when x  5, it comes out as 25, not -25 as it multiplies x by -1, than squares it

Gave me a little trouble ;)

My fountain was going downward rather than upward and i was baffled until i did a quick check on my math. Very important stuff ;)

Glyndder - Why are you ASKING people to do things for you? I believe you know where the 'pspiofilemgr.h' header is in your SDK. Not to mention a quick source code skim of multiple apps will help you without having people do it for you, in a sense.

Or you couldd use the dirent library. Google dirent in C or directory browser dirent in C.

See what happens

[Glynnder]

thanks!
I didnt think of looking at the io header in the sdk.

if(dfd > 0){
int f=0;for(f=0;f<MAX_ENTRIES;f++){if(photoEntry[f].name){free(photoEntry[f].name);}photoEntry[f].name = NULL;}
int count = 0;count = 0;
while(sceIoDread(dfd, &dir) > 0){
static char* name;
name = (char*)memalign(16,300);
sprintf(name,"%s/%s", root, dir.d_name);
static int s=0;
s=strlen(name);
photoEntry[count].name = strupr(name);
photoEntry[count].length = s;
// check for a file
if (FIO_S_IFREG & (dir.d_stat.st_mode & FIO_S_IFMT)) {
photoEntry[count].type =FIO_SO_IFREG;
}
// check for a folder
if (FIO_S_IFDIR & (dir.d_stat.st_mode & FIO_S_IFMT)) 
{
photoEntry[count].type =FIO_SO_IFDIR;
}
count++;if(count>MAX_ENTRIES-1){count = MAX_ENTRIES-1;}
photoEntriesTotal = count;if(photoEntriesTotal < 0){photoEntriesTotal = 0;}
}
}
sceIoDclose(dfd);


}

and my photoEntry struct is this :

struct PhotoEntry
{
char *name;
int type;
int length;
};

and its defined like this :

#define MAX_ENTRIES 100
struct PhotoEntry photoEntry[MAX_ENTRIES];

TUW - I do so hate your un-indenting coding methods... with a passion ;)

[the unique warrior]

TUW - I do so hate your un-indenting coding methods... with a passion ;)

You do??!!! oh well what can I say .... its me :)

[MaTiAz]

You do??!!! oh well what can I say .... its me :)

I agree with SG57, code which isn't indented is horrible to read. Indent, it's good for everyone, the writers and the readers :P

Actually, when I started coding, I kinda just started indenting like automatically, I couldn't even think about NOT indenting :P

But yeah, whatever. Anyone have any idea how the DH Launcher launches devhook? I can't find anything on a quick look in the launcher sources

[the unique warrior]

if you guys check uflash's source out you'll see that its indented :)
and that code was simply taken from ps2de forums I only changed the sruct and added file type and length .
:P

[SG57]

mATIAZ - I dont have a PSP, so cant help you there... As for the indenting, i do it automatically since it makes my code structured in a sense, and i can easily go back and forth without getting lost in nested loops and whatnot. I dont see how TUW gets anything efficiently done ;) jk

EDIT

Ok, gotcha ;)

[1337PSPer]

i normaly indent when i'm cleaning up the code befor release

[the unique warrior]

well its better to code indented ;)

[zwnage]

Hello. I'm trying to get a scrollbar working. It's halfway here, but I can't seem to find the error that is keeping it from being 100% working.

Anyways, what I am trying to do is display only 5 words in a list of 9 words, lets say as an example; 1000, 2000, 3000, .... 9000. So for instance, it would display 1000 to 5000 on startup: ex
1000
2000
3000
4000
5000

One of the numbers would be highlighted, for instance; 1000. When you scroll down, only the 2000 will be highlighted instead. When you scroll past 3000, instead of just highlighting the next number, the whole list will move down, ex:
2000
3000
4000 (now highlighted)
5000
6000

and so on.

It works okay, exept that my code displays something like this:
1000
20001000
300020001000
4000300020001000
50004000300020001000

The highlighting and scrolling work like I intended, by for some reason, each line repeats all the numbers. Here is my code, can anyone spot the problem? Thanks!

P.S. Ignore any extra includes and such in the code, it will be part of a bigger code.

[hallo007]

please don't edit the SDK if you don't know how to...
so hallo007 use SE-SDK with the real SDK don't change it!
Thanks,
TUW

how do you do that??
justput it in pspdev??
sdk/
HENsdk/
-= Double Post =-
how doyou let the user select an file in a map if you dont know wich files and how any files there are in
(like an mpplayer)

[MaTiAz]

As for the indenting, i do it automatically since it makes my code structured in a sense, and i can easily go back and forth without getting lost in nested loops and whatnot. I dont see how TUW gets anything efficiently done ;) jk

Yeah, exactly :P

[yaustar]

....

That didn't give you warnings or errors?

char test1 [4] = "1000";
char test2 [4] = "2000";
char test3 [4] = "3000";
char test4 [4] = "4000";
char test5 [4] = "5000";
char test6 [4] = "6000";
char test7 [4] = "7000";
char test8 [4] = "8000";
char test9 [4] = "9000";

The array is not large enough for the strings as it doesn't have enough room for a null terminator.

Switch it to:

char test1 [] = "1000";
char test2 [] = "2000";
char test3 [] = "3000";
char test4 [] = "4000";
char test5 [] = "5000";
char test6 [] = "6000";
char test7 [] = "7000";
char test8 [] = "8000";
char test9 [] = "9000";

[SG57]

Or, to put it another way... Every character array must be terminated by a NULL char. that char is '\0'. By not setting a character array's size on declaration, anything you initializing it to, will automatically size the array to how ever amny chars there are + 1 null terminating char...

You could have also just changed the 4 to 5 as the size of the arrays. But, if you plan to make a 5 digit number or word in the strings anywhere, best increase it to whatever you need (5 digits = 6, 6 digits = 7, etc.)

But heads way is perfect (saves you time counting)

[1337PSPer]

ok how would i go about making an app which can go from plain text to ascii and back the other way is there any straight forward code or would it be quite complex to code?

how hard would it be to port this code over it looks very much like C (i know it's java script)

char test6 [4] = "6000";
char test7 [4] = "7000";
char test8 [4] = "8000";
char test9 [4] = "9000";

The array is not large enough for the strings as it doesn't have enough room for a null terminator.

Actually he's overallocating. It would be perfectly valid to define char test1[1] = "1000"; as the actual data is static text.

Thanks for the help! I increased the array size, and it works now! Thanks a bunch, I would have never been able to find that error myself (and there was no error warnings). :)

mafia1ft: Plain text is ascii

Actually he's overallocating. It would be perfectly valid to define char test1[1] = "1000"; as the actual data is static text.

I still think he is under allocating as he is explictly allocating 4 bytes for the string whereas

char * text = "dslkfljsf";

Would be fine.

Ok, I am new to PSP programming although I have some experience with C++.

I am using PSP-Programming as a guide to get me started with the basics. I understand quite a bit now. My question is wtf is wrong with this!!!!!! LOL. I get an error that I dont really understand. Could someone please tell me why I get this error/s

error: Syntax error before "}" token.

I really need some help with this. Could someone explian to me whjy I get this error. My code is below. It is a simple image load from PSP-Programming. Help. It looks way better on Bloodshed so please bear with me. :P

I typed all of it except a comment by hand. There may be spelling errors, but I do not see any.

This type of definition is called a Macro Function.

Basically, what this function will do is return the value of X
if it is greater than Y, or the value of Y if X is less than Y.
The syntax of a Macro Function is "NAME (TEST ? TRUE : FALSE)"
where NAME is the identifier, TEST is the equivalent of what would go in the parenthesis of an if statement,
TRUE is what to return if the TEST result is true, and FALSE is what to return if the TEST result is false.*/
