I'm in the middle of creating a ePOS for my uncle and so far I've created a database for it where it will create, update and delete records successfully.
My next step I would like to do is to create a printer till thing, but how do I connect my database to that ?
I can create a till but how do I do link my database with it? I followed this example here [URL] ....
I have so far tried MySQL++, ODBC, SimpleDB, and the MySQL C++ Connector. All of them give me a FLOOD of errors in the output. Is there an easy way to connect?

So... I'd liked to save the details from <scanpre> to sqlite db. Also i'd liked to load the details to <scanmed> from my db (name,price,form, etc.)
I have created 2 form which is login form, which username textbox already connected to the database and it is successfully. When user login, it direct to the second form, and in the second form, there are multiple textbox that i have created using Array List, and it has shown.
Here is my problem: I want to connect the textboxes in second form to the database, but it shown nothing when i run the program, i already trace the code which is the error, and the error is on when OleDBDataReader is reading, i dunno what's wrong with my code, in login form it run perfectly, but in the second form, there is an error.
Here is the image for Login Form:
Here is the image for Second Form:
Here is the code for Second Form: [CODE]

For the Second Form, in the column of code, it supposed to shown the autocomplete like at the Login Form.

Are there anyways to pause the loop until either LCONTROL or RCONTROL is pressed?
Are there alternatives to stopping LCONTROL and RCONTROL increasing or decreasing counter by a huge sum?

I think I need to use
Code:
while(input[0]!='
'){
scanf("%s", input)
printf("%s", pointerhere);
}
basically we were asked to make a program that will print everything before the user hits the enter button. we cannot use fgets and we have to use pointers here.
not sure what exactly to do. We were told not to use fgets cause it's so easy and we need to incorporate pointers in this project..
I am using fin.peek() to read character from input file and saving each character into an array. Each line from the input has first name, last name, id number, and then 5-6 grades. Random spacing between each one.
input file example:
Adam Zeller 45678 80 87 60 90 88 100
David Young 34521 34 56 76 76 76 76
Carl Wilson 909034 90 90 90 49 39
my code for reading in and storing each character is this:
while(fin.peek() == ' ')
fin.get();
while(fin.peek() != ' ') ///// first name {
c = fin.get();
first[i] = c;
[Code] ....
The problem I am having is what sort of loop would go around this to read till end of file. I have tried eof. I have tried while(!fin.peek == ') and I have tried a couple of other methods. these methods resulted in a never ending loop execution.
So I made a simple letter guessing game a while ago and I want to make a simple edit. If the user does not press 'y' or 'n' and instead inputs an invalid letter, I want the printf's in the main function to loop until the user chooses to play or quit.
And I want the choices to show up again at the end of a game. Basically I want it to keep asking if the user wants to play until the user chooses to exit. Here's my code:
#include <stdio.h>
#include <time.h>
#define MAX_GUESSES 6
void Instructions ( ); //displays instructions, returns nothing
char Play ( ); //this functions plays one game, returns W if user wins & L if user runs out of tries
[Code] .....
I'm thinking of making a separate function (like Instructions and Play) ... But how would I link the user input back to the main function?
I have a event called dataTree_AfterSelect in which I have some code which I want to execute as atomic operation like this:
protected void dataTree_AfterSelect(event params)
{
code that should not be disturbed
}
What is happening now is, I am able to select another node of tree & in that case another execution of above function starts causing a garbled result.
What I want is, user should be able to click on tree node but execution of code block should only start after first execution is totally over.
It seems to be going null. I can't get a null value, I want it to accept input till the user hits enter with no text typed. I've tried checking to see if the input is NULL, "", and " " all to no avail.

Is there a way to access the printer in ANSI C ?
I have written a program and would like to print out the data (held in a file).
All I can find is that there seems to be no way to send a file to the printer and stay within the confines of ANSI C.
I am restricting my use to ANSI specs for the portability. Do I have any options?
The problem is when i run this program and program is stop working but the output is out.

take a look at this project : [URL] i want to change this project for this purpose : when a USB PRINTER is connected show a message that tell us -> hey this is a printer. which part of this project should i change and how can i separate printer devices from the others?
note: if you are using visual studio 2010 or higher and get error for this line after conversion :
#define _WIN32_WINNT 0x403
just replace all of such these lines to stdafx.cpp file. means stdafx.cpp at last should be like this :
// stdafx.cpp : source file that includes just the standard includes
// HWDetect.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information
#define _WIN32_WINNT 0x403
#include "stdafx.h"
I'm not new to C++ programming but I'm not an expert either. I'm using Borland C++ builder 5. I know it's extremely antiquated, but I have no choice right now. Writing a database reporting program, using third party report building components (ACE) which has it's own print dialogs built in. However, in this report we cannot use the build in dialogs and have to use a standard TPrintDialog. When the TPrintDialog is executed and you click print on the dialog, only one page is sent to the printer.
Here's some code:
// The dataset for the report is executed prior to this code and does not //change.
Once the data is gathered, the report can be run as often as you like // and the same data will appear in the report.
Code:
if (cbxShowForm->Checked){
OverlayBand->Visible = true;
AllowPrint = false;
SctReport1->Prompt = false;// disables ACE Reporter Print Dialog
SctReport2->Prompt = false;

Write a program to simulate a printer queue (priority queue or heap – Bentley article has code) where 3 printers are “fed” by this queue. Each print job has an unchanging priority and higher priority jobs go first (although once started, a job isn't stopped to let a higher one go). For each unit of time, there is a 26% probability that a job will be added to the queue and all jobs take 8 time units to complete. Print job priorities are between 5 and 100. The queue opens 20 time units prior to the start of printing for adding print “jobs”. A print “day” is 1000 time units. The output from your program is:
1) A list of jobs completed with their priorities for each printer
2) A list of jobs not completed (if any).

I have a test web page and a windows form which call a printer and sends a print job to a printer that is on the network. I have been able to successfully do this from the windows form, however, I can figure out how to do it from an aspx page to the server's default printer. Sample codes are below.
Windows Form:
public partial class Form1 : Form {
private const string TEMPLATE_DIRECTORY = @"C:Program FilesBrother bPAC3 SDKTemplates"; // Template file path
private const string TEMPLATE_SIMPLE = "NamePlate1.LBX"; // Template file name
private const string TEMPLATE_FRAME = "NamePlate2.LBX"; // Template file name
public Form1() {
InitializeComponent();

We have an assignment in which we have to implement a printer spooler using linked lists. I have used the list from STL to implement everything. I can get the program to send the print command and maintain status of documents. The problem is I don't know how to mimic/send a dummy print command so the document gets printed. If I use Sleep() there is a delay in the whole program.while I want printing on backhand and others users to have access to the program.
