I want to have my program only clear a section of the lines displayed on screen. For example if:
Welcome. Enter : (cin)
Choose a mode: (cin)
(etc...)
Clear above lines (for example) 1 and 2?: (cin)
//now I want the program to do that. How?
Overall, I want to be able to system ("cls") only certain lines.
I am having a problem with my c++ code. I am attempting to clear the text off of the command prompt screen in a text based game program. I put a restart option using a goto in my program. How would I be able to clear all previously displayed text.

If any exception occurs in critical section code then what sort of issue which we see in terms of synchronization objects?
Before and after the critical section code, Mutex is locked and unlocked. But if any exception occurs then the waiting thread will be waiting for resource to be freed as Mutex is not unlocked due to the exception.

I am having trouble with the implementation section of my code. The trouble I am having is with the """"string Name::RevereUsingString()""" function/method. I keep getting an error saying that """"control reaches end of non-void function"""". The two void function below the ""string Name::RevereUsingString()"" fuction/method are ok and ready to be worked on.
How to implement the ""string Name::RevereUsingString()"" correctly in the implementation section?

I am using a thread in my application .. A DLL is written for In and Out instructions for hardware ICS and to read FIFO.
My code is
CCriticalSection crdll , crsec ;
UINT ThreadReceiveData(LPVOID param) {
for ( ; ; ) {
if (bTerminate) break; // bTerminate = 1 in Doc template destructor
crdll.Lock();
[Code] ....
I am confused , how and when I should use Ctitical Section ? The program works fine but I am not happy as this is main routine of the program and I have not understood it properly.
Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.
I'm trying to create a piece of code similar to the code I have created on the new username section which will allow me to put certain restrictions on how my new users log in i.e the password length and the the need for a numeric digit. I also need storing my new members details in my previously created array.
case 'N': //Set up new user
Console.Write("
Create new Member details
");
Console.Write("
Create new Username
must be 8 characters, all letters, 1 Capital letter");

I am facing an issue with re entrance of one of my dll module. I had MLClient.dll which load in to program using LoadLibrary(MLClient.dll)
boost:: shared_ptr will add a lock() on this Load & initialization of library.
Due some of my requirements I want to un initialize this library and unload.?
How can i do the same with windows functions.?
How can i leave the lock on library using boost::shared_ptr.?
un load if there is a lock() on it ?

I have turbo c++ on windows xp SP2.....whenever i compile my code in turbo c++ i am getting output outside the screen.....but when i used code::block....i get the correct output...fits to screen ...
View 7 Replies View RelatedSo i am struggling for days to get this done and all i need is to get the sum of the areas and get them printed on the screen my code is this:
Code:

#include <stdlib.h>

#define PI 3.1415
float Area_of_Rectangular(float length,float width);

My problem is :
Code: numbers[10]={25,27,17,19,47,3,98,5,124,10};
You write a program at do below processes for above array.
You want a number 1 between 10 at user.
if user enter N value,program write to screen lowest N. number at array. For example user enter 2,program write to screen lowest secondary number of 5 value at array or user enter 10 value,program write to screen maximum number of 124 value at array.
But write the program with don't use sorting algorithm.
I have a one simple question :D. I want to output to the console some symbols. Let's say that i have a loop.
for(int i = 0; i < 10; i++) cou << "* ";
Then I want to output other symbols but I want to overwrite the previous symbols. I know I can use system("cls"); but it blinks if I try to output the same characters. For example if I have:
for(int i = 0; i < 10; i++) cou << "* ";
system("cls");
for(int i = 0; i < 10; i++) cou << "* ";
After I run this code the first loop outputs ten "*". Then there is a blink and there are again ten "*" shown. How can I avoid this blink?

Is there any way I can clear only a selected part of the screen? (I'm aware of system("cls"))
For example, when you enter a date, and is wrong, could it just errase that input and only say "Wrong try again" without errasing everything else you where doing?
In this case, a function that only errases what is in the while
while(not wrong)
{
cout<<"DIA: ";
cin>>obj.dia;
cout<<"MES: ";
cin>>obj.mes;
cout<<"ANIO: ";
cin>>obj.anio;
}
PS: Also, is there any whay in which you can ask the user to enter the date DD/MM/YYY?

I can't seem to make the correct logic/engine of this nested loop.
I had a program (on console) that uses a third-part software to draw some graphs. In order to hold the graphs on the screen, I used cin.get(); and that worked.
Now I created a GUI with Qt. The code remains generally the same. The code continues to call the software to draw graphs (during drawing graphs, there is a console opened automatically). Butcin.get(); in the code cannot hold the graphs on screen anymore. The graphs appear and disappear immediately.
Screen Splitter will allow main screen to be split into two or more sections. It will be useful for the active program's window to be resized properly to one part of the screen. Using this utility, User will be able to do a split system desktop into two or more areas....
