Right now I am trying to make an alarm clock type program that will start on login and will go off when a certain time is reached. I also want to set a password that will prevent system use until the correct password is entered into the program's input. What functions will I need and how are they used?
View 1 RepliesI am developing a program that needs auto start at windows startup. For that I need to add Registry entries. Also the program needs to read some registry keys. What are the functions i need to do these.. Simply I need to
check if the startup key already exists
add a new key if it doesn't exist
read a key values
I want to start a time intensive function after showing a modal cdialog. How can I do this?
Starting the function in OnInitDialog do not work because the dialog is not shown, then.
This code is for (hospital management system).
This code allow you to add patients.
There are two types of patients. which is:
1. Normal patient.
2. Critically ill patient.
once you added any patient. You will be able to show all patient using "ShowAllPatient;" method. -> i want the Auto-increment ID Number to appear for each patient has been added.
And you will be able to call a patient to provide a hospital services for him/her using "GetNextPatient;" method.
I need to generate an Auto-increment Number for each (patient) has been added. (Auto-increment Number) but it just should be different for each patient. For example the first patient will have 1, The second patient will have 2. etc. The Auto-increment number should appear for each patient.
i want to add a prompt at the start of my program which ask a user to enter its password wat will be its syntax it is confusing me alot i have written this code but its gving me a problem
int security(char *num)
{
char pass[10];
ifstream file("pass.txt", ios::in);

My motive is to get random variable at every start of program. So it does not show same sequence when it run again and again ....
Code:

srand( time ( NULL ) );
cout<<rand();

When I run this program in code::block the following program is opening with error in new tab called TIME.H
Code:

I am writing a program to auto login in a web site. Before making next attempt I have to wait for some time like some 10 seconds(it is configurable). But during waiting UI should not freeze. I wrote code something like this. Here event m_hEvent[1]) will be set by another thread after 10 seconds.The problem is UI still freezes some times!
while(1)
{
//m_hEvent[1] will be set by another thread after 10 seconds
dwRet = MsgWaitForMultipleObjects(1, &m_hEvent[1], FALSE, dwMilliseconds, QS_ALLINPUT);
ResetEvent(m_hEvent[1]);

I want to know if there is a function or library that starts counting time when the program starts. Because I'm making a program that is dependent on time.
Pseudo code
time starts
if ( seconds % 2 == 0 ) {
counter++;
}
Why do i get this error?

I am creating a WinForm registration application and my program accepts user input information and stores it but I am struggling to use my login function.

Is there a way to auto align a cpp file?
View 7 Replies View RelatedCode using auto-implemented property:
public class MyClass {
public int age { get; set; }
}
static void Main(string[] args) {
MyClass testing = new MyClass();
testing.age = 44;
Console.WriteLine(testing.age);
}
output: 44
Code using regular variable declaration:
public class MyClass {
public int age;
}
static void Main(string[] args) {
MyClass testing = new MyClass();
testing.age = 44;
Console.WriteLine(testing.age);
}
output: 44
Why use the auto-implemented property when you can just as equally use the second code block to achieve the same thing?
I write these code in 2 different ways and I get the same result. I just want to make sure that they both are for declare a pointer using "auto"
The first one:
int varName = 10;
auto var1 = &varName;
cout << var1 << endl; //prints, varName address
cout << *var1 << endl; //prints, varName value
The second one:
int varName = 10;
auto *var2 = &varName;
cout << var2 << endl; //prints, varName address
cout << *var2 << endl; //prints, varName value
It doesn't matter if I put dereference operator or not, I still get the same result. I just want to make sure that var1 and var2 are both a pointer.
I'm having trouble with auto and decltype.
void f(const vector<int>& a, vector<float>& b) {
typedef decltype(a[0]*b[0]) Tmp;
for (int i=0; i < b.size(); ++i) {
auto p0 = new auto(a[i]*b[i]);
auto p1 = new decltype(a[i]*b[i]);
[Code] ....
The above code runs well in GCC4.7.
Could I use 'new auto(a[0]*b[0])' to allocate memory for the type of a[0]*b[0]？
And I can not distinguish the difference between decltype and auto in this case.
I presently use the turbo C++ IDE. it has the red background(changeable) and all that but it does not have auto completion for curly braces.

Once more. The google search page is open.[Type anything on google.com and then THAT next page is the one ..] **So , the search box ,where you enter text has fixed coordinates.. (Which website doesnt matter, only coordinates do!)
I want the mouse to go to those coordinates, *click* and now a cursor will appear on the search box.
After this I want to send a fixed string output...That is , it should actually type in the string in that search box. then press enter.
That's it . [P.S. - obviously I don't want to do this with google, that was just an example.]
Mini Algorithm-
1)Get the mouse pointer to the x-y coords
2)Click!
3)Type in the fixed string.
4)Enter..
I can put it in a loop, don't bother with the easy bits I need to know how to control the mouse, and how to send the input string. Code snippets would be perfect

View 2 Replies View RelatedBackground: I'm making a small game using CodeBlocks and SDL. All of the code resides in a class named Game - the only thing running in Main is the creation of the Game object and the class function execute(). So far, I've made a Start Menu with three clickable buttons. I'm in the midst of making one of the buttons - Load Game - change the game screen to the Load Game menu. Basically, when the user clicks the button, the image on screen changes according to the button they click.
Issue: After successfully making the Load Game button change the image on the screen, I found that the SDL window mysteriously closes out several seconds after the image change. What is causing this - the window stays on perfectly fine until the background image is changed and the only way to break the loop is for the player to click the x on the window. I've gone over the code several times and haven't found anything that might be the cause.
Code:
Game.h file
#ifndef GAME_H
#define GAME_H
#include "SDL/SDL.h"
#include "SDL/SDL_ttf.h"
#include <iostream>
#include <cstdlib>
[Code] ....
Output:
- Window with an Start Menu image and a button with the words "Load Game".
- If user clicks the X on the window, the window closes.
- If user clicks "Load Game" button, Start Menu image changes to Load Game image. After about seven seconds, the window automatically closes out. This isn't supposed to happen.
I created a table called registration and I have set an auto increment ID for each record. The problem is when I delete a certain record the ID didn't remove or deleted, for example if I entered these records: -
1,Bob,Bob123,Bob_2@hotmail.com then if I deleted it the next id record will be 2 which is supposed to be 1.
here is the SQL Command:-
CREATE TABLE Registration (
Reg_Id INT PRIMARY KEY IDENTITY,
Name varchar (255),
UserName varchar(255) NOT NULL,
Reg_Password varchar(255),
Email varchar(255),
Reg_Rank varchar(255)
);
I wanna store my data by descending order auto without doing a classification after , i have come up with a code but it crashes.
Code:
void list::create(int num) {
struct node * n,*temp;
n=new node;
n->data=num;
if(head==NULL)

I don't wanna use the list library with the push.buck, i need to do it by coding it without fix functions ....
I thought I'd display my fun use of the new C++11 auto keyword to create a compile time foreach. It only works for STL collections, or anything that implements the STL collection iterator methods begin(), end() that return a STL iterator.
// Standard Template Library foreach
// element = iterator name
// collection = STL data collection variable
#define stl_foreach(element, collection)
for(auto element = collection.begin(), __end__ = collection.end();
element != __end__; element++)
}
