C :: Selection Menu With Enter Key Support
Apr 27, 2013I am working on a database project, which can store (initially) 10,000 marksheets with following capabilities
1) new entry
2) edit/modification of entry
3)delete entry
4) separate Departements ( BBA, BCS, M.Phil, Phd., etc.)
5) can store data on files ( initially, all data is stored in a single file)
Now, I want to create a menu, in which i can use arrow keys to navigate through the menu and use Enter key fo selection.
What should i use in it?? The project is only on C language.
C/C++ :: Menu Selection Does Not Continue To Desired Screen
Mar 8, 2014Basically we have to create a system for loan amortization for vehicle company. The code is still in its development stage and I am having problems with one of the menu selections. all the other menu selections work fine except for menu selection 3. I'm quite stuck on it. When I run the program everything goes well except when I enter 3 at the main menu, it just exits the program instead of going to the screen for the menu selection.
#include<stdio.h>
#include<conio.h>
#include<string.h>
main() {

C++ :: Selection Process Using Roulette Wheel Selection?
Feb 9, 2013I'm trying to make a selection process using roulette wheel selection. To do this I created two matrix, one random probabilities and one increasing probabilities. The idea is to choose a number according to the random probabilities. Here is the code I've written.
#include <iostream>
#include <conio.h>
#include <cstdlib>
using namespace std;
int main (){
float select [5], prob [10], mat [5];
int c, r, z;
cout.precision (2);
cout << "Random Number:" << endl;
[Code]...
The result I got is as follows:
Random Number:
0.0013 0.56 0.19 0.81 0.59
Increasing Probabilities:
0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1
Selected Column:
0
5
6
8
9
The evaluation doesnt seem to start from c=0 again. The selected column should be 0, 5, 1, 8, 5.
C++ :: Menu Program Broken Down Into Series Of Calls To Function For Each Of Menu Items
Aug 19, 2013I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
C :: Program Based On Menu System - Option To Go Back To A Previous Menu
Apr 7, 2014I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
C++ :: Dot Operator Versus Arrow
Jun 26, 2014I understand that the dot operator is:
Code: a.b "a"
is the actual object (not a memory location) and "b" is the member. I also understand the arrow to mean:
Code: a->b "a"
is a pointer to a struct and "b" is it's member so "a" is dereferenced then "b" is given.
Here is where I get a little confused. I have a class:
exampleclass.h
Code:
#ifndef EXAMPLECLASS_H_INCLUDED
#define EXAMPLECLASS_H_INCLUDED
class exampleclass{

Also if ec1 had a public variable and I wanted to access it would it be referenced the same way as the method I call in ec1?
C++ :: Visual Arrow Following Motion Of Ball?

Mar 2, 2014So I have assigned this method to each TextBox. It works fine pressing the left arrow and right arrow, but for some reason will not work using the up and down arrows. I have tested the string, using MessageBox and it is correct...the loop even proves it finds a matching TextBox. It is correct as in it displays the TextBox name it should be selecting but doesn't. I have no clue! Now the first select method is the one I want to use, I used the loop to check to see if it was even finding a match. It does find it but doesn't select it. The naming convention for my text boxes is r1c1 where the first number indicates the row and the second number is the column. There are 9 rows and 9 columns. This SHOULD be working but for whatever reason it is not. I've even put a message box inside the if statement for the up and down keypress check and it pops up when i press up or down.
private void Navigate(object sender, KeyEventArgs e) {
TextBox input = (TextBox)sender;
string nextBox = input.Name.ToString();
if (e.KeyCode == Keys.Left) {
if (int.Parse(nextBox.Substring(1, 1)) > 1 && int.Parse(nextBox.Substring(3, 1)) == 1)

C Sharp :: How To Detect Whenever Down Arrow Key Is Pressed
Jun 3, 2012So, I've been working on a project recently, and the only thing remaining to do is a detector to whenever down arrow key is pressed. The down arrow key can only trigger when a certain check box is checked and this will have to work with a timer either. The problem is that how to make the down arrow key press detector(I've got the check box and timer ready tho).

May 13, 2012I'm trying to implement this on ubuntu, to compile and run only under ubuntu.
I found 100s of other attempts at answering the general question of arrow key press in c++. Nothing solid.
Some recommend using the Readline for the functionality I am trying to implement, but I need to stay clear of GNU licences if I can for this project. And some tips only work on projects for windows machines... for example the conio library.
For linux there may be the option of using the ncurses library which I will take a look at, but I am stubborn and want to implement this myself. It should be an easy straight forward thing to do, which is why I am a bit frustrated at the moment.
Here is my test code so far.
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] ....
So! This works... 80% of the problem is solved. If you compile this, g++ under linux, ubuntu in my case, and run. Each keystroke reveals the correct key numbers.
q=113
w=119
when I click on the up key I get,
up = 279165
I thought, I can use this number is a if(int == '279165') to detect the up key.
I was not so lucky... this int is not behaving like an int!
So I modified the code to see it I could carry out an int operation on this number.
I added a 100000 to int i.
cout<< i + 100000;
Code:
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] .....
Compiling and running this, and pressing the UP key gives the following number.
100027100091100065
Some some sort of array, something like, [27][91][65].
I tried all ways to access these individual numbers, actually the third one for comparison purposes, but no luck.
For completeness sake I list the other arrows.
UP = [27][91][65]
DOWN = [27][91][66]
LEFT = [27][91][68]
RIGHT = [27][91][67]
A little further digging shows that these numbers are derived from the representation of a "multi-char" constant, the data type given when pressing special characters...
Now here is the main problem I have, I can find ANY decent documentation on how to handle and play with "multi-char" .
C :: Double Use Of Arrow Operator With Pointer / Function
Feb 24, 2015I have recently come across a function call that I do not understand. It uses the arrow operator for a function call, twice, and I don't understand.
Code:
static inline void b43_write32(struct b43_wldev *dev, u16 offset, u32 value)
{
dev->dev->write32(dev->dev, offset, value);
}
I see that the function itself does not return anything but calls another function. The main difficulty I have is with the "dev->dev->" operator, where dev, I expect is a pointer to a structure.
C++ :: Array Char Rotation And Arrow Key Usage

Visual C++ :: Enable / Disable Menu Item 2 In OnUpdate Handler Of Menu Item 1?
Sep 15, 2014I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well.

C# :: Invert ListBox Selection?
Apr 18, 2014I have my ListBox working and I'm able to select the items I want to keep. I'm trying to now get the Invert of the current selection for the items to delete.
I tried using:
if (lstLinePatterns == null) return;
for (int i = 0; i < lstLinePatterns.Items.Count; i++)
lstLinePatterns.Items[i].Selected = !lstLinePatterns.Items[i].Selected;
But
.Selected
is giving me an object error.
Is there an easy way to just inverse current selection?
Current Code:
private void btnSelectNonRvt_Click(object sender, EventArgs e)
{
// Unselects any Items to Prevent Infinite Loop
lstLinePatterns.SelectedIndex = -1;
