need some help text veiwer (should be simple to solve)

[kriogenic]

Ok well im not EXACTLY new to C and have made a simple text veiwer so far it is static and loads the one file this is temp till i make a file browsder to go before hand but first off i need help with the following things

[HELP] Where there is a ENTER in text file
[HELP] Scrolling when text file is too large

here is what is up with the enter in text file...

when the app is loaded it uses the fopen command to open the file and then i allocate it some memory then i print it to screen but were ever there was an enter in the text file it comes up with a musical note and i would just go through the text files and add \n but thats a pain when i add the file browser and it isnt static anymore so i need help on fixing that.

and the scrolling thing the text goes off the page and i dont know how to make it scrollable using the D pad so help with this would also be appreciated

Thanks,
Kriogenic.

Hi, this thread should help you with the "note symbol"
http://www.psp-programming.com/dev-forum/viewtopic.php?t=1176
For the scrolling, I never done nothing like this, but I think is could be easy impemented drawing only the required line on the screen and, with a variable, keep track of the current line, so if you play down, the number is increased so the firs line dissapear and a new one appear on the bottom.

swordman thanks for the help i will look at that topic and also try what you said with the variables

any chance on a very simplistic file browser source?

To get scrolling only read a-b amount of lines from the file, when the user press down a++ b++...

Thanks harleyg that helped alot now i need to work on that file browser if anyone has a simple file browser source that would be good

[kriogenic]

one more thing.. Im making it do each letter not line so when i do a++ and b++ it only increases the chars not lines how would i make it do lines? ill post my code up shortly.

EDIT:

and i also am having problems with the (NOTE) problem at the end of each line this it my code

Code:

int main (void) {
     pspDebugScreenInit();
     SetupCallbacks();

   FILE *pFile;
   char buffer[100];
   int fileLen = 0;
   char c = 0;
   int ready = 0;
   int count = 0;
   int i = 0;
   
   pFile = fopen("myfile.txt","r");
   if (!pFile){
      printf("Error. File not opened.\n");
      sceKernelSleepThread();
   }
   // Get File Length
   fseek(pFile,0,SEEK_END);
   fileLen = ftell(pFile);
   fseek(pFile,0,SEEK_SET);

   while(ready == 0){
      i = 0;
      sprintf(buffer," ");
      count = 0;
      while(1){
         c = fgetc(pFile);
         if (c == 0X0D)   //0x0D is the Line Return
            break;
         if (c == EOF){
            ready = 1;
            break;
         }
         if (c != 0x0A){
            buffer[count] = c;
            count = count + 1;
         }
      }
      printf(buffer,"\n");
   }
   fclose(pFile);

     sceKernelSleepThread();
     return 0;
}

im using the myfile.txt because filename is when i get the file browser

have it read one line then have it print untill a symbol(that u defined) then have it \n then have it do another printf (yes this is a very noobish way but it should work

Mmmmm, I really should learn file i/o. I know a few commands, but not enough to do anything useful. Maybe I'll learn it when I write the skin system for 0x89.
