Why multiple entries in combo boxes?
private void Form1_Load(object sender, EventArgs e) {
try {
connection.Open();
OleDbCommand command=new OleDbCommand();
command.Connection=connection;
string query="select * from korisnici,dogadjaji";

I've finally managed to do something with the combo box but knock down one wall it's like there's another one five inches behind it. What I mean is I've figured out how to add items to the combo box and have them show images in my picture box. Only problem is when I went to debug my combo box kept looping it's options over and over and over.
Private Sub
xpmaleskincolorselect.Items.Add("Tone1"); malesprite.Image = My.Resources.Resources.XP_Female_clear;
xpmaleskincolorselect.Items.Add("Tone2"); malesprite.Image = My.Resources.Resources.XP_Male_tan;
xpmaleskincolorselect.Items.Add("Tone3"); malesprite.Image = My.Resources.Resources.XP_Male_dark;
End Sub
The subs, I know they aren't right but its just to show I know where they go. Anyway using Private Sub and End sub doesn't seem to work. I'll type them in then at the error box at the bottom it'll say that it doesn't exist in the namespace. Same thing happened when I tried to add public class beforehand to see if that would work same thing about the name space.
Here's what i'm searching for: I have a form with 3 pictureBoxes (pictureBox1,2,3). The form also contains one button.
What I want is that when the user clicks the button (so button_click event) that the 3 pictureBoxes each show a different picture. And when I click the button again again 3 different pictures will load.
I already found out that I need to make an arraylist for the pictures (there are about 100 pictures). A System.Random
to select random images. But I have absolutely no clue on how to write this code.
How would I be able to let the user enter multiple heart rates which would all be separate.
Code:
printf("Enter your recorded Heart Rates ");
scanf("%d", &in_rate);
//formulas
if (gender == 'm'){
target = 226 - age;
} else if (gender == 'f'){

I have to create a program that holds three arrays one for the persons last name one for the points scored and one for the player number, now i've got all the arrays and things done but i'm confused as to how i'm going to delete an entry so far the options i've got working are create player, list player, update player, retrieve player and exit.

I have an array of size m and r resources. What would be an efficient (or just any) way of distributing them in the way shown in the table? The highest amount of resources must be concentrated in the middle of the array and all the resources must be distributed.
I'm not really set on exactly how steep the "slope" must be, I just need a way of approaching the problem.
Example with m=9 and r=13
box resources
0 0
1 0
2 2
3 2
4 4
5 2
6 2
7 1
8 0
Basically, I am designing a form that shows all of the services a mechanic performs, and then it is supposed to calculate the total based on the selections made.
HOW do I use those check boxes to calculate a total? I am supposed to use value-returning methods that solve for the parts cost, flush charges, tax charges, misc costs, etc. Ive attached a picture of the form thus to make sense of what I'm trying to describe.
So I am writing a multiform multiclass project for a class and I initially set out to create a validate class to check all of my text boxes. However after writing a few simple boolean functions to check if the box was empty or not, or if it was indeed an integer, decimal ect. I realized I was going to have to call these functions for every text box and also have all of my decision making based on the returned boolean variable still in the code portion of my form. I was wondering how do most people do it, should I write a class that validates the entire form at once(one form has 7 text boxes, one has 9). I suppose I am asking what would the industry standard be, how would a professional do it? While my simple functions would work, and while I could write one large function that validates them all at once both paths leave something to be desired in terms of re-usability for the entire form validation, and compact/cleanliness of code for the simple functions.
My validate class currently stands like this:
class Validate {
bool isValid = true;
int trash;
bool valid_string(string input) //parameter is textbox.text property {
if (input == string.Empty)

I have a c# form that has two pictureboxes on it. I use two webcams I want the first webcam to allways show it's image in picturebox 1 and the second webcam to allways show it's image in picturebox 2.
How can I write this and stop that annoying popup dialog asking me to select a webcam each time it runs.
How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3
INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7
INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0
OUTPUT – The sum of the volume is 812.806
OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream>
using namespace std;
double box(double length, double width, double height); // use double data
int main() {
double sum;
sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);

I've recently started creating a bingo caller application. I need in changing numbers to different text boxes. When a number is called it will be displayed in a text box and the last four numbers previous to that. However the oldest number needs to delete and for the remening numbers to move when a new number is called.

Basically, say i wanted to sum all the values enter for x. First, i ask the user how many x's there are, then create a "for" loop to ask for x1, x2, x3, .. xn. Then i want to know the cumulative total of x. How would i do this? This is the sample code i have made right now inside of my main function:
Code:
int N;
int I;
int X;
//This is where i ask for how many x's there are//
}

when i declare local variable x and use it in array,the error is occure that use of un assign local variable.

I'm creating a program that holds three arrays one for the persons last name, one for the points scored and one for the player number, now I've got all the arrays and everything done but I'm not sure as to how I'm going to delete an entry for multiple arrays.

It compiles just fine and it will add new entries and print the entries just fine but when I go to delete an entry it will delete it but it will mess up the one before it.

Now for assigning unique control ID I'm creating a static control from resource editor and destroying it before calling CStatic::Create() and using its control ID say ID_STATIC_SAMPLE.
If I do not use this parameter of Create(), the static control is also being created, so what is the use of this unique ID. And any other better way to assign a ID for dynamically created static controls.

When I compile I get this error:
Code:
simpleauth.c: In function ‘initialize_table’:
simpleauth.c:179:30: error: incompatible types when assigning to type ‘DBEntry’ from type ‘void *’
I am sure its a simple error but I cannot seem to figure out how to set all the entries in the database to NULL. My plan is this:
1. Set all entries to NULL.
2. Check if entry is empty, if empty insert into hash-location, if not increment until empty...
Part 2 seems easy to me, but I cannot set them to empty....
how to do this? ask the user to input entries of 10x10 array. sort each column into increasing order. print out the array with sorted columns?

I am writing a program that deals with 2d arrays. The program inputs the number of rows and columns and asks for the entries. When the program run and compiles it works perfectly until it outputs then it gives me a warning.
Here is my code:

using namespace std;
int main()
{
int row1=0,col1=0,i,j;
//int a[row1][col1];

I am learning how to do this before I can move on so it can read a text file of numbers.
Also I am having problems with ////delete [] a[];///// I took it out because it made my code compile and run but when I add it in, it gives me an error:
matrixtesting.cpp|56|error: expected primary-expression before ']' token|
I know this expression is suppose to deallocate the array.
