I'm currently doing a project which will trigger an alarm and light up an LED when a character 'E' is detected from a bluetooth input. I'm supposed to program a pic18f4525 board.
I'm having troubles with where to start on the codes to enable the LED to light up upon detection of character 'E'. I'm using ports RD0-RD3. This is how I initialised them in the main loop.
Code:
TRISD = 0b11000000;
PORTD = 0xC0;
Am I doing the initialising right? Also, how to program it to light up when the character's detected?
I have a question related to switch statement, which the switch in class employee2 gives me error at output. Program compiled well. I am using Code::Block Compiler V10.5. I have created object of class employee2 in main() function to get data from user, store it and display it. At the output, Compiler doesn't show actual output what i am expecting. The fun thing is my compiler printed emocion like (), where (hourly/monthly/weekly) was supposed to print.
Code: #include <iostream> using namespace std; enum period {hourly,weekly,monthly}; class employee2 { private : char ch; period x; double compensation;
I recently upgraded my operating system from Windows XP to Windows 7 SP1 64 bit. We are using Visual Studio 2008 Professional Edition and Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production.
When I try to execute this code I am getting the below exceptions
HTML Code: try { CDatabase *pDatabase = CDatabaseConnection::getDatabaseConnectionProcessLog(); ORSProcessLog rsProcessLog(pDatabase);
[Code] .....
Where rsProcessLog is the CRecordset object using a successfully connected database pointer pDatabase
In 32- bit Debug version I get a message box at rsProcessLog.Close(); with the below text Debug Error
Program: ......Test.exe
HEAP CORRUPTION DETECTED: after Normal block (#506) at 0x0087F628. CRT detected that the application wrote to memory after end of heap buffer.
Memory allocated at f:ddvctoolsvc7libsshipatlmfcsrcmfcdbcore.cpp(2626)
(Please Retry to debug the application)
In 32- bit Release version I get a message box at rsProcessLog.Close(); with the below text Windows has triggered a breakpoint in Test.exe
This may be due to a corruption of the heap, which indicates a bug in Test.exe or any of the DLLS it has loaded.
This may also be due to the user pressing F12 while Test.exe has focus.
The output window may have more diagnostic information.
The above code was a working code in Windows XP with the rest of the env remaining the same and it continues to run in Windows XP but not in Windows 7.
what 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.
I am trying to make a program which manages the data of 5 different patients (its an uni assignment), and i want to use a switch case as a menu to switch between the patients. All other functions (as for example putting the infromation on a file) work, but i cant figure out to bring the switch to work. First it asks for the number of the patient which should be worked with, this works perfectly, but afterwards changiung between the persons doesnt work as thought. It should ask everytime after it switches to one patient (i removed some functions to make it easier to read) and then asks to which it should jump next. If i put the number of one case (lets say 3) it just stops the program.
********Example: user@pc ~/wherever $ ./program current variables: jo = 2 a = 0 1 //the entered number The variable a = 1 patient 1 Enter the number of the next patient2 // and then it closes **************
The same thing happens if i compile an example code from a book, it writes the first case and then stops.
I looked already through the forum but didnt find a person with a similar problem, maybe i didnt dig deep enough.
I am running Linux Mint 17 and use gcc as compiler.
Code:
include <stdio.h> #include <stdlib.h> int a=0; int jo=2; int main(void){ printf("current variables: jo = %d a = %d
I want to make something like some users using the same machine so they need to be registered to the system and the their id something like this (H510698541) and their information should appear on the screen.
okay so like case 2 and 3 is not working, also the program is still not finish but why isn't case 2 and 3 not functioning well on the switch part? case 1 works just fine
Code: #include<stdio.h> main () { //passcode part (passcode is 1234)
Switch case statements are a substitute for long if statements that compare a variable to several "integral" values ("integral" values are simply values that can be expressed as an integer, such as the value of a char).
So does that mean switch statements can only test if variable == value and nothing more, like > < >= <= != etc... ? I tried to make a program to test this and it seems like switch statements are limited to == but I'm not sure, maybe I'm doing something wrong.
This is the program I tried to make to test this:
Code: #include <stdio.h> int main () { int n;
[Code]....
So is it true that switch statements only work with the built in == operator? if that was the case then I would feel rather meh about switch statements.
so I am trying to have an switch statement array. but every time i complete a case statement the whole process is returned. the thing is i want the menu to stay up even if i complete the case.
I'm making a game in OpenGL GLUT. A ball is going to move forwards along the Z axis and hit a wall. I want to be able to move the ball left and right, up and down before firing it off on the Z axis. I'm using glutSpecialKeys for this, and I've got everything set up, but I'm not sure how I use it with a switch statement? Here is a snippet of code:
void Special_Keys (int key, int x, int y){ switch(key){ case GLUT_KEY_UP: //do something break; case GLUT_KEY_DOWN: //do something
[Code] .....
Where the comment is saying "do something", I'm not sure what I actually need to do? Is it a method or what?
Please select: 1 - Year 2 - Day 3 - Month Input choice: 1 Input Number: 2 I'm a Sophomore!
Please select: 1 - Year 2 - Day 3 - Month Input choice: 2 Input Number: 2 It's Tuesday.
Please select: 1 - Year 2 - Day 3 - Month Input choice: 3 Input Number: 2 February. Heart's month!
Here is my code, I only typed the Year(levels) yet because when I tried to input 2(day) and 3(month) for the Input choice and after that, Inputting a number to 1-4 would yield the same result to case 1's year levels.
#include <stdio.h> #include <conio.h> using namespace std;
[Code].....
how to link the case 2 to days and case 3 to months?
I am using a switch statement as a menu. If I enter a non-integer value as my choice, I expect the error message , "Invalid entry", to display but instead the output keeps running.
I have tried to search all about strings,I have the occurrences and have worked out what letter corresponds with which. I have searched that much i can remove the vowels and reverse my string but I dont know how to swap them. This is what i have this far. When it compiles it just prints the decipher is:
If i even find out am i on the right track ive used caps when swapping to try and stop the doubles over writing,...
#include<stdio.h> #include<string.h> int main(void){ int i,count=0; char secretText[] = "lopsy, hssepokd wl okrhsowk:
The error ive been getting with this code is after i go to the check out option, enter the data then click (ctrl + z). Then program glitches back and forth from the menu to the check out option continuously and im not entirely sure why.
Heres my code:
[#include <iostream> #include <windows.h> #include <iomanip> #include <fstream> using namespace std; void records(){ cout << setw(10) << "Ministry of Health Hospital System
While running a Doc/View SDI, is there any way to switch from text mode to rtf mode during runtime? Search reveals nothing.
Say I have an editor and I want the app to use text, I can set the ctor as follows.
Code:
CEditorDoc::CEditorDoc() { // TODO: add one-time construction code here m_bRTF = FALSE; }
But once I've done that and compiled the app, while it's running, is there a way for the user (or programmer) to change the mode back to RTF? One solution that occurred to me is to use 2 document classes, but that's a hassle.
OverLay[0]=ini_read_string(map_file_ini,_T("Section"),_T("Key"),_T("NULL")); if(OverLay[0]==_T("NULL"))MessageBox(NULL,_T("File or kay not exists"),_T("Error"),MB_ICONEXCLAMATION|MB_OK);
but the key dos not exists, so it will return NULL, but yet i am not getting the message box (LPCWSTR) i also dit try
and ther it is, an message box with the text "NULL" so why is the if(OverLay[0]==xxx) not working? and i also need a big list so an working switch(OverLay[0]) will be nice as well (else i need to do if/ else if many times)
I was getting errors and I looked into the error and it told me to fix it by adding Code: { } in my case statements. I did, it compiled but fell through the whole thing. Lets say I enter 1, it outputs the was not found 5 times in a row.
Code: void addressbook::EditNameOrDate() { std::cout << "Enter 1 to Edit the contacts First Name: " << " "; std::cout << "Enter 2 to Edit the contacts Last Name: " << " "; std::cout << "Enter 3 to Edit the contacts Street Address: " << "
How to do i fix this code im not good at using function, im trying to pass a statement from switch to my double passengersR i always come out with a error
this output: Name passenger: Enter number passenger: Choose from A to D if choose A Total Regular Passenger: 6.19624e-312
did i do something wrong im not really good at function and im trying to learn how to pass switch to void function
Code:
#include<conio.h> #include <iostream> #include <Iomanip> #include <string> using namespace std; double passengersR () { double m;
