C :: Disable Interrupt In ARM M0 Program
May 6, 2014
How do i disable the interrupt in this ARM M0 univesity design start program? The design is made for the M0 and echos an inputted char as an integer, it is part of a larger piece of code (which is ommitted for simplicity).Can i do it in the main program(attached) or will i have to edit the assembler code.
Code:
// Cortex-M0 DesignStart C program example
#include <stdio.h>
#include <time.h>
#include <rt_misc.h>
#include <stdlib.h>
}
[code]....

I brought some code from a PICDEM DV lab example into a simple program I'd written. The example showed how to use the external interrupt on the PIC16F690 to switch directions in a function.
I've been trying to use that RA2 pin as both the input (start) trigger for one of my functions and as an interrupt to get out of that function, too. So far the interrupt doesn't work, but the function trigger does. Should I use two pushbuttons or add a random timer to the for() loop to execute the function to roll the dice?
Trying to incorporate that example code also seems to have messed up the little random counter [a for() loop] that I used. The dice pattern was reliably random before adding this new stuff, and now I can clearly see repetition.
I'm only just starting a MC class.
Code:
#pragma config FOSC = INTRCIO // Oscillator Selection bit
#pragma config WDTE = OFF // Watchdog Timer Enable bit
#pragma config PWRTE = OFF // Power-up Timer Enable bit

This is a program that is for a robotic car. The car has two light sensors on the front to detect when it veers off the road. When a sense is detected on one of the sensors the corresponding motor will halt until the sensor again detects the track. Again two sensors, left and right, and two motors (one per wheel). I have case statements to do the two left and right sensors.
how would I implement a third sensor with an interrupt to halt the car after it senses a stoping line. E.g. the sensor in the middle detects the stopping point so both motors halt.Here is the code I have so far...The cases are the sensor detections.
Code:
#include <hidef.h> /* common defines and macros */
#include "derivative.h" /* derivative-specific definitions */
// Function Prototypes
void init_PWM(void);
void initLCD(void);
[code]....
}

I have a program that makes a directory (temporary) and in it some files that are necessary for computation while program is running. Now suppose a user decides to interrupt the program at some stage. what happens is that the program stops but my folder and files remain.
Q: How to override SIGINT command so that before the the execution stops the folder is deleted ?

i have tried to search on the Internet but haven't found a suitable result that links in with what I want to do, that is to creation a WPF application and when you press a enable button it will enable the LAN and when I click the disable button it will disable the LAN until i click the enable button again. Now I know how to creation a WPF and the buttons, but how would I do the disabling LAN and enabling LAN?
By LAN i mean just the networking adapters, so that the PC cannot connect to a router and then the Internet.

I want to disable optimization in Visual C++ 2010. In gcc on Linux I could just use the -O0 switch, but in Visual C++ 2010 there are two categories of optimizations, one in the C/C++ pane and the other in the Linker pane:
Attachment 33229
So what settings should I choose to make sure that no optimization is being performed?

I have an application in c# that i don't want it to connect to the internet in a virtual environment, like virtualbox, vmware virtual pc and so on. Therefore i though that disabling the virtual network card inside the virtual machine would be a good idea.

I have ploughed through the exchanges in all the forums, yet I still cannot make it work. The following is a tiny Code::Blocks program, written to isolate the problem:
// resource.h
#define IDR_MYMENU101
#define ID_FILE 102
#define ID_DISABLE103
#define ID_ENABLE 104
#define ID_MESSAGE105
#define ID_EXIT106
[code].....
case ID_ENABLE is similar to case ID_DISABLE above, and neither works. case ID_MESSAGE and case ID_EXIT both works as expected.I have tinkered with EnableMenuItem(), but without success.

how to disable selection of 1'st row in dataGridView.
I made it select some other row, but even so when u try to move with arrows on keyboard it'll select 2'nd row(cause 1'st row was selected initially and you can see it's selected on RowHeader-1'st/Left Column)
This is my code for selecting row:
dataGridView1.ClearSelection();
dataGridView1.Rows[BoPrI].Selected = true;
dataGridView1.FirstDisplayedScrollingRowIndex = BoPrI;
BoPrI is int variable that has Index Value

I have created an exam environment for our schools, it comprises of 3 files; a .kix file that says if they are in the examination group run a .vbs file. The .vbs file kills the explorer.exe task so they don't have any taskbar or desktop shortcuts and then opens a .hta file.
The .hta file is a user interface that has icons for apps like Win Word that executes the application when you click on it. There is also a log off button.
Looking for some code that stops the students from being able to close, minimise and resize the window. Looking for code that can lock this down so they literally can't do anything except click the icons inside the window.

I need to be able to disable the items on a CCheckListBox but I can't change the code that calls AddString. I know I can use the CCheckListBox::Enable function to disable an item if I have an index but I don't have the index which would be provided by AddString.
I've tried intercepting the LB_ADDSTRING message and then looping through the items in the control but the string has not been added at this point so the last item in the list is never disabled.
I used Spy++ to see what messages were being sent and I noticed that LB_GETTEXT was sent so I tried intercepting this message (ugly hack) but this caused my app to hang - I assume because of the number of times the message is sent. Is there a way to disable the items?

I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
Code:
void CDummyView::OnUpdateMenuItem1(CCmdUI* pCmdUI)
{
if(m_bShowMenuItem1) {
pCmdUI->Enable(TRUE);

so my homework assignment is to make a program of which removes any notes in a program file.
for example, you run my program it will ask for a filename, when entered it opens the file, copies everything in it and removes any double forward slashes (//) and anything after that up to the new line character ( ) and anything between /* and */ including the /* and */.
i created the entire program and it removed the // and anything after that up to the new line character but will not remove anything after the first / when it finds a /*. This includes the */ at the end of the comment.
the section of code that removes the comments is
//this loop removes all notes
for(i=0;i<buf.st_size;i++) {
if((filecontent[i]=='/')&&(filecontent[i+1]=='/'))//removes notes using //
{
for(i=i;filecontent[i]!='
';i++)
filecontent[i]=' ';}
[Code]....
i know that the section that removes the multi line comments would not remove the final */ at the end if it did work, i was planning to fix that later once it removed the comment.

My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
so far i have this
#include "stdafx.h"
#include "student.h"
student::student(vector<STUDENT> studenti) {
vStudent=studenti;
[Code] ....
I try to make it but its too difficult for me. in that student.h and student .cpp is 50 errors..
Here is my code
#include "stdafx.h"
#include <string>
#include <vector>

I've been working on a small SDL program and decided I wanted to throw the program on to a disc so I could show some people what I'm working on. However, when I try to run the executable, the program crashes and under more details it says that the fault lies on SDL2_ttf.dll .
Why does this program work inside of VS2012e and not in windows?
What I did :
Set the program to release, hit f6, and then tried to run the executable from windows.
Additional information :
Compiler : Visual Studio 2012 express
O/S : Windows 7 64bit
SDL lib : 32 bit version

is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10
Enter 3rd number: 30
Largest = 30
Smallest = 10

I am working on a program to compute the natural log of numbers using several different methods, but I am having a couple of issues. Firstly, when using Borchardt's Algorithm I almost always end up with nan as a result, even though I am pretty sure I got the formula correct. Also, in my lnDemo.c file It doesnt give me the correct answer and the second time around I get a segmentation fault.
Code:
//myLog.h-------------------------------------------------------
//These functions will compute or aproximate the natural log of a number
//This method will use a formula to compute it
int lnFormula(double x, int m,double *result);

I have an issue with a switch case in my program. I execute it and it does fine all the way up to where it says, "Answer (1, 2, or 3): ". When I enter 1, 2, or 3, it gives me' "Not an input choice!" from the default of the switch case.
NOTE: I use Code::Blocks on Windows XP.
Here is the code:
Code:

#include <string.h>
