Hi,

Trying to read from a file using dbReadString and it's not returning anything.

Here's the code:

+ Code Snippet

char szLine[ 1024 ];

if( dbFileExist( "level.txt" ) ) {

	OutputDebugString( "file exists\n" );
	dbOpenToRead( 1, "level.txt" );

	if( dbFileOpen( 1 ) ) {
		OutputDebugString( "opened the file\n" );

		while( !dbFileEnd( 1 ) ) {
			//sprintf( szLine, "%c", dbReadByte( 1 ) );

			dbReadString( 1, szLine );
			OutputDebugString( szLine );

			//OutputDebugString( "\n" );
		}

		dbCloseFile( 1 );
	}
}

You can see my commented out lines to use dbReadByte() instead. That works fine. What's busted with dbReadString() or what am I doing wrong?

Thanks.

Yeah it works.

You could do it two ways that I know of. One using pointers or just using dbPrint.

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK(void)
{

char szLine[20];
char *pstring;


if( dbFileExist( "level.txt" ) )
{

	dbPrint( "file exists\n" );
	dbOpenToRead( 1, "level.txt" );

	if( dbFileOpen( 1 ) ) {
		dbPrint( "opened the file\n" );

		while( !dbFileEnd( 1 ) ) 
		{
			//sprintf( szLine, "%c", dbReadByte( 1 ) );

		pstring = dbReadString( 1, szLine );
		dbPrint(pstring);
	dbWaitKey();

			//OutputDebugString( "\n" );
		}

		dbCloseFile( 1 );
	}
}


dbSync();


}

or

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK(void)
{

char szLine[20];
char *pstring;
//while (LoopGDK())
//{


if( dbFileExist( "level.txt" ) )
{

	dbPrint( "file exists\n" );
	dbOpenToRead( 1, "level.txt" );

	if( dbFileOpen( 1 ) ) {
		dbPrint( "opened the file\n" );

		while( !dbFileEnd( 1 ) ) 
		{
			//sprintf( szLine, "%c", dbReadByte( 1 ) );

		
			dbPrint(dbReadString( 1, szLine ));
			dbWaitKey();

			//OutputDebugString( "\n" );
		}

		dbCloseFile( 1 );
	}
}


dbSync();
//}

}

Ok, Thanks.

Why does it take in a character array if it doesn't fill it and instead just returns a character pointer?

That makes no sense at all.
