i have seen it several times in the dbpro boards something about entry (1) tried that no arguments accepted, blah blah blah. even if i dbkeystate(14) the backspace button i still havnt found a way to actually allow it to remove the last symbol typed. is there a command to do this, or a chunk of code that will do the same thing?

i am still a bit new to this (NoOb)

Currently i have something like this for code.

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );

	//In screen curently
		
	while ( LoopGDK ( ) )
	{
		if (dbScanCode()==14)
		{
			dbClearEntryBuffer ();
		}
		char* login = dbEntry ();
		dbText (10, 10, login);
		dbSync ( );
	}

	// return back to windows
	return;
}

I just want to make a simple login screen for now. none of the dbPro codesnips or tutorials seem to conver over to gdk. realy starting to get agrivated. i was able to make a simple AI system in a few hours ove spent 3 days on a friken text box and i dont even have a box yet lol

or is ther no way to do this in gdk? am i suposed to use normal cpp for these aspects. i had realy wanted to keep everything in game.

????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
Wonders if no one is helping because they them selves dont know. or is there another reason?

i mean im not asking for your soul. a simple hi sorry i cant help would work. and maybe the next person will say the same thing in which case i ditch gdk. its of no use to me if i cant input text in a normal manner.

You should use GDK for visual and then C++ for normal file, in/out-put

Your must call dbCLS() at the beginning of your loop.

Try this:

+ Code Snippet

#include "DarkGDK.h"

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );

	

	//In screen curently
		
	while ( LoopGDK ( ) )
	{
		dbCLS();

		if (dbScanCode()==14)
		{
			dbClearEntryBuffer ();
		}
		char* login = dbEntry ();
		dbText (10, 10, login);
		dbSync ( );
	}

	// return back to windows
	return;
}

FINAL VERSION RELEASED!!!!

I've just glanced over this post whilst eating a sandwhich quickly but as long as I understand you right then you may gain the knowledge you need from this snippet from Iro's console code:

+ Code Snippet

if (dbScanCode() != 0 && dbScanCode() != KEY_BACKSPACE && dbScanCode() != KEY_ENTER) {
		szUserInput += dbGetEntry();		
	} else {
		if (dbScanCode() == KEY_BACKSPACE) {
			if (dbTimer() - nBackspaceTimer > BACKSPACE_PAUSE) {
				if (szUserInput.size() > 0) {
					szUserInput.resize(szUserInput.size() - 1);
					nBackspaceTimer = dbTimer();
				}
			}
		}

		if (dbScanCode() == KEY_ENTER) {
			if (dbTimer() - nNewLineTimer > NEWLINE_PAUSE) {
				if (szUserInput.size() > 0) {
					DoConsoleCommand(szUserInput);
					szUserInput.clear();
					nConsoleBufferIndex = 0;
					nNewLineTimer = dbTimer();
				}
			}
		}
	}

	dbClearEntryBuffer();

the variables with the word Timer in them are simply integers used to stop the same command repeating really fast when a user holds down a key.
the KEY_blah variables are constants holding the scan codes of the keys im checking. (Backspace = 14, enter/return = 28)

Hopefully that helps. If you dont understand some part, just ask

EDIT:

should point out that szUserInput is a c++ string object.

ok i first tried Sephnroth's code, but the .size and .resize commands were throwing me off. when ever i tried to compile it vis c++ 08 says they were not defined. not sure why. but reading the code i can see its rely useful and pretty much what i need to get to work.

on the other hand tobi453's added dbCls. does work but it clears the entire line of text.

so i gues the question is whats the deal with the .function saying this error

.........left of '.clear' must have class/struct/union
type is ''unknown-type''

EDIT:

Quote: "

"

So i need to include the string.h file? i tried that and it doesn't work. i also searched all the include directory's on my comp and cant locate szUserInput

ok i have something that works.

+ Code Snippet

#include "DArkGDK.h"
//------------------------------------------------------------------------------------------------
void DarkGDK ( void ){ 
//------------------------------------------------------------------------------------------------
  char szCharBuffer [ 1020 ] = ""; // huge just cuz I felt like it
  
  dbPrint("Type Something!");
  strcat(szCharBuffer,dbInput());// Notice - I THINK 
  // Everything will stop during this. Makes Sense really - but keep in mind :)
  
  dbSyncOn();
  while ( LoopGDK ( ) ){
   dbCLS(); //cls not needed while 3d objects around - then screen fully redrawn so not needed
   // in fact - you might delete your 3d rendering with it then!!!!!!
   dbSetCursor(0,0);
   dbPrint("You typed:");
   dbSetCursor(110,0);
   dbPrint(szCharBuffer);
   dbSync ( );
  };


};
//------------------------------------------------------------------------------------------------

I found it in a topic aboutr dbInput somewhere deep in the gdk forum alows the entry of text and backspace works. there realy should be a gdk section in the code base would make life nice.

anywho thank you everyone who helped

.clear() and .resize() are members of the c++ string class.

to use it you must first include the header with:

include <string>

at the top of your file. then to declare your string variable, in this case called szUserInput, just write:

string szUserInput;

somewhere, either before the DarkGDK() function if you want it global or inside the function you use it in for a local string.

You will find c++ strings to be much easier to work with than char arrays - but not always as flexiable!

EDIT: I tried using include <string> didnt change anything. is there a sdk i need to have the file? sounds pretty common so im guessing not

ok im a bit slow. but i got that worked out >> was realy stupid didnt have the using namespace std; in the file.

i currently get one error the doConsoleCommand. i have to leave for work at the moment so i cant play with that. but i assume i need to change that to some command that will print (obviously dbPrint, and dbText failed) or convert the string to a char. not sure.

#include <string>
#include "DarkGDK.h"
using namespace std; 
// the main entry point for the application is this function
void DarkGDK ( void )
{
	
	dbSyncOn   ( );
	dbSyncRate ( 60 );

string szUserInput;
	int nBackspaceTimer;
	int nNewLineTimer;
	int nConsoleBufferIndex;
	
	while ( LoopGDK ( ) )
	{
		if (dbScanCode() != 0 && dbScanCode() != 14 && dbScanCode() != 28) 
		{
			szUserInput += dbGetEntry();		
		}
		else
		{
			if (dbScanCode() == 14) 
			{
				if (dbTimer() - nBackspaceTimer > 1) 
				{
					if (szUserInput.size() > 0) 
					{
						szUserInput.resize(szUserInput.size() - 1);
						nBackspaceTimer = dbTimer();
					}
				}
			}
			if (dbScanCode() == 28) 
			{
				if (dbTimer() - nNewLineTimer > 1) 
				{
					if (szUserInput.size() > 0) 
					{
						char* userinput=doConsoleCommand(szUserInput);//Problem
						dbText (10, 10, userinput);
						szUserInput.clear();
						nConsoleBufferIndex = 0;
						nNewLineTimer = dbTimer();
					}
				}
			}
		}

dbClearEntryBuffer();

dbSync ( );
	}

return;
}

+ Code Snippet

#include <string>
#include "DarkGDK.h"
using namespace std; 
// the main entry point for the application is this function
void DarkGDK ( void )
{
	
	dbSyncOn   ( );

sorry, I should of mentioned the std namespace! It didnt even cross my mind, my bad!

yes, replace doConsoleCommand with whatever. You can get a char array (const) from a c++ string by saying myString.c_str(); - myString being the name of the string variable.

you could, for example, draw the string to the screen with dbText - but dont do it where I do doConsoleCommand because that only fires when the user presses enter. Do it after all the code so its always there
