Hi, for me in DGDK 2.0 the dbEntry() function doesn't seem to work properly.

Whenever I type it adds the character twice so it ends up like this:

Quote: "HHeelloo wwoorrlldd.."

And the backspace function doesn't seem to work either.

Can anyone confirm this?

Don't you have to call it with a boolean argument of true (or possibly integer 1) to use the backspace feature?

Also it might cause duplicates if you hold the keys long enough I guess. I haven't tried the DGDK function however so I'm not sure whether it works correctly or not.

Indeed, the function looks like this:

+ Code Snippet

std::string dbEntry(int32_t removeBackspace = 1)

It defaults to 1.

The function seems to work okay except for the character duplicates, and I need to get a fix for that.

You could make a function that takes the next letter out from the old and add to the string to get what your wanting.

Here is how I coded my program. This is finished exactly as darkvee had mentioned.

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK( void )
{
    int length = 0; // used to obtain length of input in array

    char* buffer = ""; // used to retrieve input from dbEntry();

    char userInput[20] = ""; // used  to print input to screen

    dbSyncOn();
    dbSyncRate(60);

    while( LoopGDK() )
    {
        dbText(250,250, userInput);

        if(dbScanCode() > 0 && length <= 20) // Inerts characters upon type
        {
            buffer = dbEntry(); // writes buffer letters to the char*

            strcat(userInput, buffer); // appends the user entry to the input array

            dbClearEntryBuffer(); // clears the buffer to begin next input to add on to the input array

            length = strlen(userInput); // gets the length of the char*
        }

        if(length != 0 && dbKeyState(0x0E) == 1) // Backspaces Characters
        {
            userInput[length - 2] = '\0';
            dbWait(100);
        }

        dbSync();
    }

+ Code Snippet

string buff;
buff=dbEntry();
if (buff.length()>0){
}

I use it like this and it works for me......

The fastest code is the code never written.
