C++ :: Clear Screen Without Blinking

Nov 4, 2013

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?

C++ :: Clear Part Of The Screen?

Nov 3, 2014

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?

C/C++ :: Simple Calculator - Clear Screen Following User Input

Dec 10, 2014

I am working on a simple calculator in C++ .... All works fine with the calculator up until the requirement for the user to input "do you want to go again y/n" .... What i want to happen is the screen to clear down and reloop to the enter name part....but i can't get it to do that

Program Description: To write and develop a programme where a user can input a cost or price of something before VAT our program must then process the input number and must output the price with the original value plus VAT

#include <iostream>// I must use this to start my programming
#include <string> // I have added this for the extension task so the user has to input their name
#include <iomanip> // this is to manipulate the text
#include <stdlib.h>
using namespace std; // using the "using namespace std" shows that i will be using standard text throughout this programme

[Code] .....

C :: Finding Percentages / If Statement / Clear Screen And Reloading Program

Nov 11, 2013

For my C programming module, I've been asked to create a program which is basically a ten question mathematics quiz or test if you like. Below is a copy and paste of my current, working program.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main () {

[Code]....

I am also trying to include into my program; If the user achieves 4 or less marks in the test, they are asked if they would like to repeat the test (have a second chance).

I have been asked by my Lecturer to ask the Question; "Would you like to try again" and the response is 'Y' for yes, 'N' for no. Would this be shown by:

char Y = Y;
char N = N;
printf("Would you like another go?");
scanf(%d%, &Y, &N);

And finally; If the user would like another go, then I am trying to include the code that clears the screen and then reloads the program?

What code is used to clear the screen and no clue what code is written to refresh or reload the program. I assume it's a loop statement or some sort.

C# :: Microsoft Word Editing With Toolbars?

Dec 6, 2014

I'm trying to create a program for my wife to be able to browser through and edit folders and specifically word documents- really just a shiny organization tool without having to open up Word. I'll be integrating other functions into this program but Word is what I'm worried about.

At the moment I've been able to create a file browser with the ability to add and remove files within the main directory of the program. Basically just C:Users\%user%mainDirdata*

Within the data folder I have the main folders which will be displayed as tabs across the top and then any subfolders of the main folders will be displayed on the left side after you click on the main tab.

[URL]

I'd need the toolbars to be integrated into the program across the top and then a window that changes depending on the document selected on the left side based on the content of the word document located in that folder. I haven't been able to find anything online and I'm not really able to spend $800 on the alternates that look like they just do automation as well.

C++ :: Microsoft Code For Keyboard Input Interpretation?

Nov 22, 2013

at the moment my program is extracting keyboard data through accessing the virtual key states. However, it is not performing as I intended because the data I receive from the console does not concur with the actions the user performed.

E.G. When I type, it comes out like this.

what I get with my program: WWhhhheeen III typeeee, iiit ccoommes oout lllikkke thhhhiiis

TLDR: so basically Id like to know how other programs know how to interpret keyboard input, so that when I type I dont get multiple inputs of the same key press

Visual C++ :: How To Implement Crosshairs (whole Screen) In MDI-App

Nov 28, 2013

I am working on a solution for the above problem. Without success by now. To draw it within OnMouseMove with XOR-operation in not a good solution.

One problem: OnMouseMove is not called if the mouse moves to outside the CView-window.

But in this case the crosshairs should be deleted.

Second: working with XOR will not be good because we need a defined state (visible/not visible).

Visual C++ :: How To Determine If A Metro App Is Currently Displayed On The Screen

Apr 22, 2014

I'm trying to determine (from my Win32 process) if a Metro (or a Modern UI) app is currently displayed on the screen. I found the IAppVisibility::GetAppVisibilityOnMonitor method that can do just that, and I even found a C++ sample, but my issue is that I'm compiling it with the Visual Studio 2008 that does not have the definitions for the IAppVisibility interface, so the following:

Code:
#include <Shobjidl.h> //Earlier version
IAppVisibility* pAppVis = NULL;
HRESULT hr = CoCreateInstance(CLSID_AppVisibility, NULL, CLSCTX_INPROC_SERVER,
IID_IAppVisibility, (void**) &pAppVis);

Results in a set of errors:

Code:
error C2065: 'IAppVisibility' : undeclared identifier
error C2065: 'IID_IAppVisibility' : undeclared identifier

how to define them?

Visual C++ :: Grab Screen(s) And Invert Their Brightness

Jan 15, 2014

I have a visual impairment that makes it very hard for me to use the standard dark text on white background themes. I use High Contrast but many apps don't query the system for colors (I.E. aren't theme-aware) and consequently display pale or dark text on a white background regarding of the theme selected.

There is a product called ZoomText that allows for inverting the brightness of everything being displayed. I just use a normal theme, let all apps display naturally, and then invert the entire screens brightness.

But ZoomText doesn't support multiple monitors. And it does a lot more than I need. And it hogs the CPU. And it costs a lot.

Looking for some of the APIs that I need to capture the bitmaps for all monitors, invert the brightness of all pixels, and refresh the display contexts. And make that happen so smoothly that it appears like there is nothing going on behind the scenes. (DirectX, OpenGL, ???)

Visual C++ :: Draw Multiple Lines And Move Them On Screen

Jul 28, 2013

I am writing a pure C based win32 applications. I have drawn line. Now i want to translate that line, move the line whereved user wants to move on screen. Then again I drawn another line, I am drawing multiple lines.

I have created rectangle region for each line and trying to move the line.

When I move the 2nd line over the 1st line on screen the 1st line is getting wiped out. Because I am InvalidateRect() of the rect for the line being moved, so when that rectangle is crossing the other line then the other line is getting removed from the screen.

How can I rectify it. How can I have all the lined being on the screen and moved according to the user's wish. The code should be pure C and win32 no MFC.

Visual C++ :: Floating CDialogbar On Multiple Screen Environment

Jul 11, 2014

I have an problem with a CDialogbar if my app runs on a system with two screens (side by side). I can not resize it while the CDialogbar is in floating state on the second screen.

I figured out that the problem is the mfc-function CDockContext::Stretch().

It limits the CDialogbar to the primary screen (using ::GetDesktopWindow() to verify the position).

What can I do?

Visual C++ :: How To Detect If Window Media Player Is Running In Full Screen Mode

Jan 21, 2013

How can I check if window media player is running in full screen mode & topmost in c++ MFC?

What I used is this logic:

I compared media player full screen coordinates to that of monitor coordinates.If they are same implies media player is in fullscreen.But it has one flaw.Whenever there are control(for play,pause) displayed in full screen in media player, coordinates are not coming same as that of monitor.

Visual C++ :: Internet Explorer Displays Blank Page When Opening Local File While Screen Is Off?

Apr 28, 2015

I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.

I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):

Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);

This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)

This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)

So I started looking into it:

1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.

2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.

3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.

And why is IE showing a blank page only when computer is running unattended?

C/C++ :: How To Clear Nested Stl Map

May 21, 2013

here is a nested stl map

typedef struct struct_RISCP {    
        float nSCPTotal;
        int nSCPCount;
        CString strIMEI;  
        std::map<UINT8, int> mapSection;    
    }RISCPSt;
map<stRncCellIdntyDmnType, RISCPSt>m_mapRISCP;

it occupied too much memory,i wanted to clear them(both outer map and inner map) ,some one told me you just need to call m_mapRISCP.clear(),then the mapSection (inner map) will be cleared automaticly,in other words, m_mapRISCP.clear() will clear both outer map and inner map.
