C++ :: Code Stops Executing After GetScores Function
Nov 11, 2014I am currently working on a c++ project that will input students and process their grades. I encountered a problem and my code stops executing after the getScores function. Im not sure what the problem is, but im guessing its something within the function and the loops.
//Name: getScores
//Description: Will get scores for student
//Parameters: None
//Return: testScore
double getScores()

C++ :: Tell A Program To Continue Executing Next Line Of Code Within Nested IF Statement?
Nov 25, 2013Is there a way to tell the program to continue reading the next line of code within a nested IF statement?
The reason I want to do this is because the two "else" statements in the following sample (the main and the nested else) will contain the same exact code and I don't want to repeat it twice. I know I can do this by creating a function and calling it from each else statement but I was just wondering if what I'm asking is even possible without using a function.
if(1 < 2) {
// yes 1 is less than 2
if(5 > 10) {
// do something
} else {
// no, 5 in not greater than 10
// here is where I want to tell the program to continue reading the next else statement

Dec 17, 2013I have this function and it works, the problem is that it couts a bunch of stuff that I don't need. What this functions does asks the user to input a job (show) and if the show is found to list all the talents (actors/actresses). If the show is not found, to print "show not found". I have the function working just need to present it better. What I want the function to do is just print "show not found" and nothing else. How I have it currently will print:
Notice how its outputting all the unnecessary information. If the job is found should look like this:

C++ :: Executing A Child Process?

and return the result back to the parent program.
this script is as follows.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then print "started" if file "/Stuff/t" does not exists, then print "stopped"
if file "/Stuff/s" does not exist then print "quit" and then quit.

C++ :: Function Not Executing Cin-statement?
Oct 16, 2012I have this problem for an assignment, and one of the functions that I created for it is nothing fancy; just a function that'll take in a number and error-check to make sure the input is valid. However, after doing it, when the program calls that function, it skips the cin statement and ends the program, without letting the user input his number. The function in question is called getSubLength.
Code:
#include <iostream>
#include <string>
#include <iomanip>
#include <cstdlib>

C++ :: OpenCV - Opening And Closing Webcam
Jan 24, 2015I am trying to switch between 2 states, and the event that determines which state i am in is based on the key i've pressed. So in this case i want the webcam to start automatically, and when key is pressed it then turns it off. The way I've done it is like this :
bool webcam_on() {
int c = 0;
VideoCapture cap(0);
if ( !cap.isOpened() ) // if not success, exit program
[Code] .....
The problem with this method is that cin.get() blocks the video stream.. I wanted something that the webcam turned on until i press some key, which would trigger the release.. How can this be done?
C++ :: Executing Multiple Functions In Program
Mar 24, 2013We have been assigned to create a program that uses multiple functions. The professor has given us code for two of the functions, one to open a file and then another one to read the files contents and output them. I have put these into my program but they will not execute. The program does run, but the functions themselves are not executing. I have practiced with other functions that contain no parameters and those run fine, but the functions she gave us have multiple parameters.
The code I have so far is below:
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
void PrintFile (string FileName, ifstream& inFile);
int main () {
ifstream inFile;
string fileName;

C# :: Editing A Parent Dialog Box Without Closing The Child
Sep 30, 2014I'm using windows forms and I have a parent dialog box that consists of a text box and a drop-down that launches a child dialog box. The child takes user input and then prints dialog to the text box in the parent. However, the output does not appear in the text box until I close the child.
Now my question is, how do I get the text to appear without closing the child? I hit a button to send the info to the text box, but it still doesn't appear until the child closes. I also need to set up a button to suspend the child so that the user can click/copy/etc the parent.

Sep 17, 2013I created a C program that extracts some information from computer and displays it on screen. It is completed today and is going to be applied to startup programs of domain machines. It runs at logon and takes somewhat 5-10 seconds to finish execution. The output is shown on console screen & user can either close the window by clicking on 'x' or pressing 'Ctrl+c' during execution. How do i prevent both of these events?
Basically the most time consuming processes are
Code: popen("systeminfo","r");
popen("wmic qfe get installedon","r");
1st command is getting OS name,version and hotfixes installed.
2nd command gives me the date of updates installed.
I then filter out data & print required information only.
C# :: StreamWriter / View Written Data Prior To Closing?
Oct 11, 2014I've found that with streamwriter(sw) the data isn't displayed with the written to document until you either leave scope or use sw.close I'd prefer to keep sw open as I will be writing to the file in and out, sometimes very frequently, but would also prefer the data to be viewed in real time. Is there an efficient way of going about this?

Visual C++ :: ActiveX Web Browser Control Not Deleting Session Cookies Even After Closing
Aug 9, 2013I have an C++ application which uses Microsoft Web browser ActiveX control to launch any URL within the application. The browser is embedded in C++ form and It's working fine with all the feature Microsoft has exposed through Interface(IID_IWebBrowser2).But while any url that is using session cookie has been launched, even after closing the browser the session cookies are not getting deleted. For example if user login info is stored as session cookies,the url is using the cookies and getting launched without asking for user log in info.
But if I close the browser, and again relaunch , the cookies should be deleted and the url will not find the cookies to be used for log in . That is not happening here. Although this is session cookies , it's not getting deleted and being used by embedded browser. However, if the url is launched in IE, it is behaving as expected.
So, Do I need to delete the cookies explicitly? If Yes, How to do that?

View 2 Replies View RelatedC++ :: Reducing Code Duplication From Common Code Calling Common Class
Apr 13, 2014I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
