Visual C++ :: How To Determine If A Metro App Is Currently Displayed On The Screen
Apr 22, 2014I'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?
C++ :: Give Appropriate Color Code For Resistor After User Input
Sep 18, 2013I am in the process of writing a program that will give the appropriate color code for a resistor after the user enters an integer value for the resistance needed and selects the tolerance form a list. My question is this: Is there a way to allow the user to enter a value such as 75000 and C++ use each digit separately, as if they entered 7 [enter], 5[enter], 0 [eneter]... and so on? But, then use the entire value as an integer too? Also, it should read a value such as: 45835, as 45000, or 1843 as 1800.

C++ :: Give Output To Child Process
Apr 15, 2012I'm trying to build a basic shell for Unix. This is the code I use to create a new process:
Code:
pid = fork();
if (pid == 0) {
setpgrp();
complexCommand(argv, isComplex);
[code] .....
Where complexCommand is a function that handles the command (uses execvp after generating the correct string out of argv). My problem is that after if while in the shell I use a program that needs to print to the screen and handle input, it doesn't work as expected. To test this, I built this small program:
Code:
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
int main() {
int x1, x2;
[code] ....
And when I use the shell I built to run it, the output is only "Enter 2 numbers" for one time. It doesn't print the result, or anything else. Is there anything I need to do in the parent process (my shell in this case) to give the child the output?
C++ :: Add And Minus From Text File Not Give Right Value
Feb 5, 2014I'm creating a bank system.
So I know to make a deposit to the balance, which add ups what is the balance to i have add.
When i run the deposit function, its work well in some ways. If balance(text file) has the value 10, add i addSum 20, the balance will become 30, same as the text file will become 30. so its work well to add positive number.
Code:
double deposit(double balance) {
double addSum = 0;
system("CLS");
cout<< "Welcome to deposit."<<endl;
cout<<"Enter a sum you wish to add to your account:";
[code]...
When I withdraw from 30 which is the balance, then i takeSum, for example i take away 30. The balance will become 30 - 30 = 0 When i make another withdraw from example -150, it will be -150.Which shows correct.
But when i make a deposit from -150 and i addSum 130, the balance shows -500, and it should had been -20.
Code:
double withdraw(double balance) {
double takeSum = 0;
system("CLS");
cout<< "Welcome to withdraw."<<endl;
cout<<"Enter a sum you wish to take away from your account:";

C++ :: Output String Depending On Color Detected In A Frame Video Feed
Jul 18, 2014what I'm trying to do is output a certain string depending on the color I see in the video feed. For right now, what I've done is threshold the feed so that everything above a certain brightness shows up as Red. Now I want to have something that says if there's any red in the feed, then I output a "1" to a text box on my user interface that's showing the feed. If there is no red, then I output a "0" to the text box.
I'm using Emgu CV C ++ with VS2010.
This is the code I have so far that isn't working correctly, it's giving me a compiler error.
cvConvertScaleAbs(frameFromCamera->Ptr.ToPointer(),frameDisplay->Ptr.ToPointer(),double(1)/16,0);
cvCvtColor(frameDisplay->Ptr.ToPointer(),frameColorDisplay->Ptr.ToPointer(),CV_GRAY2BGR);
cvThreshold(frameDisplay->Ptr.ToPointer(),maskSaturated->Ptr.ToPointer(),200,255,CV_THRESH_BINARY);
[Code] .....
and the error it's giving me
BAOTFISInterface.cpp(1010): error C2664: 'Emgu::CV::Image<TColor,TDepth> ^Emgu::CV::Image<TColor,TDepth>::InRange(Emgu::CV::Image<TColor,TDepth>

Visual C++ :: Change Default Text Attributes (font And Color)
Nov 12, 2013I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
void UnicodeTextOut(int x, int y, CString s, UINT justify,int GreyScaleFlag) {
HFONT hFontUnicode;
HFONT hfOld ;
hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial"));
[Code] ....
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?

View 3 Replies View RelatedC :: How To Prevent A User From Closing Output Screen During Execution
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.
