I'm trying to code a program in Dev-C++ for auto complete text in a web form. I'm using windows.h and mouse_event() function for move cursor position and click buttons, but I need write in a inputs/textarea a text.
View 2 RepliesThis 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 m learning c programming and i m stuck with this program for some reason.Write a program that converts alphanumeric phone number into numeric form:
O/P:
Enter phone number: CALLAT 2255288
here is the code i have written:
/** compilers shows no error **/
and O/P I get is
Enter phone number: CALLAT
/**blank space***/
Code:
#include<stdio.h>
int main(void)
{
char ch;
printf("Enter phone number:");
ch=getchar();
}

I have a non form class. I want to update label/ check status of check box etc.. in non form class ( here resides functions that contains logic). How can i do that ?

I hav created mdi parent form that contain one user control. I want to access that user control from one of the child form
View 4 Replies View RelatedThis is more of a Application Design question, Let's say I have Form1(Login), this is opened from Program.cs, when the user enters details, the Event Handler makes a instance of a class, adds the data and stores the instance within Program.cs class.
So the best thing to do here, is to close the Form1(Login) and open Form2(Main) via Program.cs so that I can send the List<Login> object with my Login instance objects to said form. This form will remain open throughout the applications use as it's like the main GUI for all the programs functions.
When I close this form, I may want to save some information before the application is terminated, so I may as well store the Login instances in Program.cs anyway.
Main stepping stone: Multiple (usually around 3 max) users can login this system if need be, which will mean closing Form2(Main) and then opening Form1(Login) so that once Form1 is closed it can recreate the From2(Main) form and pass the new List<Login> to that form.
What's the best way to do this, at the moment i'm creating the Form2 instance like so:
//....
//Detect the Login form being closed
loginForm.Closed += new EventHandler(OnLoginClosed);
//...
//Open the main form when the login is closed
private void OnLoginClosed(object sender, EventArgs e)
[Code] .....
This seems like it will work and do the job, but is there a better and cleaner way? The List<Login> will be passed to Forms which are created via Form2(Main) as this information will be needed. It's just that ive been told not to use Forms for too much data containment.
I was reading this earlier [URL] ..... and I was trying to figure out how to pick one of the words randomly from my text instead of using all the words in it.
View 4 Replies View RelatedI have a form with 2 text boxes (Email and Password)
The user fills in the text boxes and clicks on the Log in button. The code behind the log in button does the following, First connects to a table (Users) in phpmyadmin. Next runs a SQL query (SELECT * FROM `users` WHERE Email = '" + sEmail + "' AND Password = '" + sPassword + "'") sEmail being the variable created from the text entered in Email text box and the same for password.
Next if the record count == to 1 it opens up the main menu form and if the record count == 0 it fails and the user does not get to the main menu.
All of the above is fine and working however what I want to do is take over a variable from the log in form to the other forms.
The code is below for the sign in button as all my code is behind that (I think this may be where I'm going wrong).
public partial class WelcomeForm : Form{
public static string connStr = "server = localhost; " +
"database = ppw5; " +
"uid = James; " +
"pwd = buster;";
[Code] .....
And the Main menu form where I'd like to take a variable over with me, lets assume the variable is the UserID from the database table that I pull from the dTable I created.
public partial class MenuForm : Form {
//Call the CloseProgram class and create a new method called ClassClose.
CloseProgram ClassClose = new CloseProgram();
WelcomeForm User = new WelcomeForm();
public MenuForm() {
InitializeComponent();
[Code] .....
I have a program which when a button is clicked on Form1 it runs a vision system operation on an image in a window on a Form1. There are also other buttons on the Form1 which can change things like threshold levels so the inspection can be run again with different settings. It all works fine but I want to change it to remove the buttons from Form1 so that when the user clicks on a button on Form1 it opens up another form, Form2, and all the buttons which were on Form1 are now on Form2 and the image analysis should run on Form1 when the buttons are used on Form2. I have taken over all the code from Form1 to Form2 and I'm trying to make this happen by creating a new oject on Form1 which calls a method on Form2 which contains the code which was in Form1 and called when the button was clicked on Form1 - not working!! I have a constructor in Form2 but I think I have become monumentally confused.
This was the code which was on Form1 when the inspection button was clicked.
private void cmdInspectOnce_Click(object sender, EventArgs e)
{
iReturn = VisionSystem.InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
if (_imgEngines!=null && _imgEngines[0]!=null)
_imgEngines[0].cmdInspectOnce();//InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
}
I have 3 Windows Form: frmMain, frmFirstForm, and frmSecondForm.
frmMain is the form that will load when the application is started with 2 tabs to access frmFirstForm and frmSecondForm.
Here's my problem:
After making a selection from a combobox on frmFirstForm, I would like a datagridview header to change based on the selection made. Here is a list of items on one combobox: Item1, Item2, Item3, Item4. When somebody chooses Item one, the header on the datagridview on frmSecondForm should display: JohnItem1, PaulItem1, BradItem1 and so on. Those items are not part of the comboboxes, but they will be shown as header text on the datagridview on the second form either automatically or after clicking OK from frmMain. There's no OK button on frmFirstForm, but on frmMain.
The only code I have right now is the if statement on the form load on frmSecondForm. Here's what I have:
private void HeaderTextLoad() {
if(comboboxonfirstform.text = "Item1") {
datagridview1.Columns[0].HeaderText = "ItemJohn";
datagridview1.Columns[1].HeaderText = "ItemPaul";
... And so on.
}
}
Is there a way to auto align a cpp file?

public int age { get; set; }

static void Main(string[] args) {

MyClass testing = new MyClass();
testing.age = 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.
View 19 Replies View RelatedOkay so what I want to do is :- Create a program that can, say for example, switch to an already opened up google search page. Type in a given string and press enter.
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

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 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)
[Code]....
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++)
}

Apparently the default behavior with Direct2D when rendering is to scale everything I render based on the size of the render target/window. How can I prevent this? I want to decide for myself when to scale the image, regardless of the size of the window.
View 1 Replies View RelatedI referred Auto-close message box.
But i like to view the message box with out title bar and buttons. Is it possible?
I had a flawed function like this:
Code:
fn(){
char c;
if (runFirstTime){
#ifdef VC
c='';
#else
c='/';
#endif
}
... // c is used in the rest of the function to construct some pathnames
}
The problem is that the value of c is not defined the 2nd time the function is called (and subsequently). It somehow worked fine under CygWin compiled with gcc. So I didn't spot the flaw until it ran incorrectly under Windows complied with VC++ 2010. Then I found the error and changed the code to something like
Code:
fn(){
#ifdef VC
const char c='';
#else
const char c='/';
#endif
...
}
So now it works correctly under Windows. Then I re-compiled the new code with gcc and to my surprise gcc produced exactly the same binary! How can this be? Does the gcc compiler see my flaw and fix it for me somehow?
