How to know which user is logged in?
Hello,
I have a Login page which checks if the user has entered the correct password by comparing it with values in the database.
I have done this with two classes: one that gets the passwords from the sql database and another that compares this data with the data entered by the user.
I have another page to which I redirect the users once they have successfully logged in (inside the Login button function)....Last edited by Frinavale; Apr 27 '11, 02:33 PM. Reason: Formatted the question so that it is easier to read. -
Thanks a lot, I changed the pixels and its working now!Leave a comment:

How to create side-by-side boxes inside another box?
Hello,
I want to create three side-by-side boxes inside a much larger box. I have this code:
...Code:<html> <head> <link rel="stylesheet" type="text/css" href="mystyle.css" /> </head> <body> <div style="width:100%; "> <div id ="wrapper" > <p class="headerStyle" -
Sorry, I should have mentioned it earlier, I declared it as a global array. Thanks for replying, my code is working now, I used vectors to declare an array and get the file data instead of the method above.Leave a comment:

How to read from a text file?
Hello,
I am supposed to read from a text file a series of numbers and then store them in a struct array.
Here's my code:
...Code:int main() { ifstream In; string folder, filename, name2, line; int i = 0; cout << endl << "Enter the name of the folder" << endl; cout << "Follow the format: c:/your_folder_name/ -
That must be it. I tried 'do while' and now it works perfectly. Thanks a lot! :)
And thanks once again to both of you for all the replies.Leave a comment:

Yep, I tried that, but it just copies the second row instead of the first. However, I just replaced getline(myfile, line)) with ( !myfile.eof() ) in the while loop and this gives the right output. Is there anything wrong in the way I use getline then?Leave a comment:

Thanks for the replies!
There seems to be nothing wrong with the indexing since I initialized i as zero before copying the data with the code above. And in my output code I am just using a for loop going from 0 to maximum. The problem occurs somewhere in the copying.Leave a comment:
