C++ :: Insert User Values Into Database
Jun 25, 2014
I'm trying to insert into the database I created, values entered by the user. But I can't find how to insert them it looks like this:
//Go for the user infos
cout << "What is your ID ? : ";
cin >> id;
cout << "What is you letter ? : ";
cin >> letter;
cout << "Your letter is "<<letter<< " and your ID is "<<id<<"
[Code] ....
I don't know how to proceed, I receive a error here for the sql2 statement
error C2296: '<<' : illegal, left operand has type 'const char [36]'

Am using the below code to INSERT values into MSI Database (Registry table)
private void button2_Click(object sender, EventArgs e) {
String Name1 = lblDName.Name;
String Value1 = txtDName.Text;
String Name2 = lblUnisntall.Name
String Value2 = txtUninstall.Text;
[Code] ....
This code work properly, but after inserting values in MSI database.
The Value1 and value 2 are created as REG_SZ (String) but as per my requirement,
Value1, should be REG_EXPAND_SZ
Value 2, should be REG_DWORD
Need to convert them in my code and then to insert into the MSI database.

I'm working on a project where we access a tiny premade database in order to log into and access another page. I got the log in part working right, but the last part of the project asks me to lock out the account after a certain number of failed attempts. I'm not sure if I need a method to do this or if I can do it right there in the button handler. I tried creating a method to use on the object that was already there, but I'm not sure if that's the right way to go about it. It says it locks the account, but the value in the database never changes, and I don't know why.
//from the login button handler
protected void btnLogin_Click(object sender, EventArgs e) {
bool IsFound = false;
clsDataLayer dl = new clsDataLayer();
IsFound = dl.GetUser(Server.MapPath("~/AddressBook.mdb"), txtUserID.Text, txtPassword.Text);
if (IsFound) {
Response.Redirect("~/frmUpdateAddress.aspx");

Right now my application database is stored in the AppDataRoamingAppName directory.
The client has requested that the administrator choose the location for the database, and have a choice between a local machine, or an online repository.
The clients are not IT people, they are business people, and I don't think it's a good idea to let a user choose where to keep the central app database. Other users (think admin vs user) will need to download the database for use on their own local machines, which is how the issue even came up, it's kind of a shared database that only the admin can add to.
My compromise was to COPY the main database to the location of the user's choosing, then push updates to it as the main database was written to.
So after working on this today, I have the user choose a directory, I add the file path to the application settings, then I create the file and copy the database as needed to the new location (online repositories are next).

Goal: Write a program that compares the values stored in the first array to the user inputted values in the second array.
In order to fix this error: [URL]...
I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:
cin>>a2[i];

Code:
#include <stdio.h>
#include <stdlib.h>
/*
You are to write a program that will allow a user to enter infinite numbers (greater than zero)(One number at a time). You must have a way for the user to stop entering values.Once the user stops, you will immediately display the following:
The lowest number entered is:
The highest number entered is:
The number of values entered is:
The average of the numbers entered is:
*/
main() {
int userNumber=0, sum=0, count=0, highNum=0, lowNum=0, lastNum = 0;
double average;
printf("Enter a number greater than 0: (Enter -1 to stop)
");
scanf_s("%i", &userNumber);
[Code]....
My program outputs everything I need except the lowest number entered. I have been spending a considerable amount of time on this problem to no avail.

I'm just starting c++, doing tutorials. So many tutorials. I've noticed that the tutorials all assume the same thing: That the user will always do exactly as he/she is told when asked for input.
Example: "Please enter your age:"
Now, the example code might be expecting the user to type some numbers, but what if the user feels like typing out the letters of their age?
"I am ninety five thank you very much, sonny"
I could specify to the user that I only want the information in number form, but what if the user is just being a dick?
What if the user types, "none o' yer business."?
So... how to approach "fool-proofing" player input?

I can`t seem to store multiple values into my vector when a user keys in an input. Lets say a user inputs 1,2 as the first set and later keys in 3,4.
My vector gets overridden by 3 and 4. I'm trying to pass these values into a function to store them into a vector and use them in the function.
Below is my code snippet
int reconstructSecret(int x, int y) {
int getX,getY;
getX=x;
getY=y;
vector<int> myXCordVec;
vector<int> myYCordVec;

Keep track of the sum of values entered (as well as the smallest and the largest) and the number of values entered. When the loop ends, print the smallest, the largest, the number of values,and the sum of values. Note that to keep the sum, you have to decide on a unit to use for that sum; use cm.

I am having some trouble creating a listbox in visual studio. I declared an array, set initial values, and now I would like to be able to update those values. It is a pizza inventory app, so I need to update the initial values once the user has added inventory. This is the code I have for the "Update Inventory" button:
// read in value and convert to double
double dblInput = Convert.ToDouble(txtInput.Text);
// loop through ingredients and add inventory to selected ingredient
for (int i = 0; i < dblInventory.Length; i++) {
// is item at i checked for update?
if(lstInventory.GetItemCheckState(i) == CheckState.Checked)

The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.
I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.

So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.
