How can you get a monitor out of sleep mode in c#?
I tried the following, but then the monitor wakes up and falls back to sleep mode immediately.
Code:
uint SC_MONITORPOWER = 0xF170;
uint WM_SYSCOMMAND = 0x0112;
SendMessage(this.Handle, WM_SYSCOMMAND,
(IntPtr)SC_MONITORPOWER, (IntPtr)(-1));
I am developing an application which monitors file changes and also registry key changes during a driver installation. I have used this code from internet, but doesn't works.
public void WmiChangeEventTester() {
try {
WqlEventQuery query = new WqlEventQuery(
"SELECT * FROM RegistryValueChangeEvent WHERE " +
"Hive = 'HKEY_LOCAL_MACHINE'" +
@"AND KeyPath = 'SOFTWARESchneider ElectricDMODBUS' AND ValueName='CurrentVersion'");

I am working on a parallel processing server/client app with a multi-threaded server and several data processing clients, each their own process. I am trying to optimize some of the parameters, such as the size of the chunks that are read, processed, and output, and also some of the timeout values and such. I can track the time to finish a given task well enough, but it would be really nice to be able to track the cpu use. When CPU use is near 100% (on all cores) for the entire run, that is a good sign. I have noticed that with some combinations of parameters, CPU drops quite a bit for long stretches, which is not such a good sign. This app process large input files (2.5GB-65GB so far) and needs to be stable for long periods of time.
Other than sitting and staring at the task manager all day, is there a good way to track/log the CPU usage over runs that take many hours? I know that there are some apps like Everest that chart CPU use, but it would be nice to have something that would write to the same log file I am already using for other program output.
I have been trying to make a sleep function in C# that will allow the game to be briefly paused when played. I am using Unity 3D.

Now I've got the loop sorted and I can make it beep and sleep, however the beep follows 10 seconds after the sleep..Both the beep and the sleep need to happen at the same time..

What I'm trying to do is have the user input a hex number this number will then be converted to a char and displayed to the monitor this will continue until an EOF is encountered.I have the opposite of this code done which converts a char to a hex number. The problem I'm running into is how do i get a hex number from the user I used getchar() for the char2hex program. Is there any similar function for hex numbers?
this is the code for the char2hex program
#include <stdio.h>
int main(void) {
char myChar;
int counter = 0;
while(EOF != (myChar = getchar())) {
if (myChar == '')
[Code] .....
This is what i want to the program to do except it would do this continuously
#include<stdio.h>
int main() {
char myChar;
printf("Enter any hex number: ");
scanf("%x",&myChar);
printf("Equivalent Char is: %c",myChar);
system("pause");
return 0;
}
I am currently starting to attempt to make a program that can move my cursor to certain colors on my monitor. The problem is this seems like it will be 10x harder than I first thought.

Make an "analog clock" that is, a clock with hands that move. You get the time of day from the operating system through a library call. A major part of this exercise is to find the functions that give you the time of day and a way of waiting for a short period of time (e.g., a second for a clock tick) and to learn to use them based on the documentation you found. Hint: clock(), sleep().
OK, I wrote below code. It is in its primary stages and has not been completed yet.
#include <GUI.h>
#include <time.h>
#include <iostream>
using namespace Graph_lib;
[Code] .....
I expect the system in void clock_hands() (line 38) attaches hour1 (line 41) then waits for 1000 ms (using Sleep(1000)) then detaches hour1 and attaches hour2 this time. But it doesn't occur in practice. When the system reaches Sleep(1000); it seems to go into a comma! It doesn't show the hour1 so seeing the movement of clock ticks by the clock's hands will not be possible.
I have a college project which is a car racing game using C++ and the old-school graphics library BGI. After I draw the map and placed the objects(Car,obstacles,road's borders etc..)I added Sleep(); function to the function named Obstacles(); but the problem is, I can't move the car with the right&left arrows.a
Another problem,If I added a cleardevice(); command all objects disappears only the obstacles function keeps working. the Code is here:
char c;
do{
c = (char)getch();
if (c == KEY_LEFT) {
x = x - 10, x1 = x1 - 10;
} if (c == KEY_RIGHT) {
x = x + 10, x1 = x1 + 10;

note: this is not the whole code, it's only a small portion of it, not a debugging question only need a hint how to fix it.
I run the following API to put Windows XP SP3 into sleep (or standby mode) from a worker thread:
Code:
BOOL bForced = TRUE;
SetSuspendState(FALSE, bForced, FALSE);
Then in the main thread, while processing window messages:
Code:
LRESULT WindowProc(UINT message, WPARAM wParam, LPARAM lParam) {
if(message == WM_POWERBROADCAST) {
if(wParam == PBT_APMSUSPEND) {
AddLogMsg(_T("SUSPEND event received"));
[Code] ....
So when SetSuspendState is called with request for a 'forced' sleep mode, the PBT_APMSUSPEND notification is never broadcast. Only if I set forced parameter to FALSE I receive it.
PBT_APMRESUMEAUTOMATIC is received in either case.
PBT_APMSUSPEND is always received when run on Windows Vista/7.
I have two problems with the code below:
1. I cannot find a header file to #include that has the sleep function prototype.
2. When I add my own sleep function prototype, I get an unresolved external reference error (for _sleep, not sleep).
What must I #include to get the sleep function prototype? What lib must I include in the linker configuration to resolve the external reference? (I suspect that if I #include the correct header file, the second question might become moot.)
The "man page" at [URL] .... says the header file is <WinBase.h>. But #include'g only <WinBase.h> results in compilation errors.
A response marked "answer" at [URL] ..... says <windows.h> [sic]. #Include'g only <Windows.h> does eliminate the compilation errors.
But apparently that does not bring in the sleep function prototype. Neither does also subsequently #include'g <WinBase.h>. (Which seems to be #include'd by <Windows.h> anyway.)
But even with my own function prototype shown below, I get an unresolved external reference for _sleep. Is that a symptom of my problem: my sleep reference is changed to _sleep? If so, how can avoid that?
According to "man page" (see link above), the external should be resolve in kernel32.lib. And kernel32.lib does appear in the "Additional Dependencies" list under Configuration Properties Linker Input.
Since I am not using C++ features, I tried setting "Compile as C" under Configuration Properties C/C++ Advanced, to no avail.

I have to find mean,mode and median of a 2-D array :
2 5 2 5 9 5 8 3 6 10
8 1 10 10 7 1 4 4 3 8
4 3 1 2 4 10 3 9 8 5
6 10 8 3 6 10 5 1 2 5

7 1 3 6 2 4 6 7 8 9
8 5 9 2 3 2 1 5 1 8

I've been trying for over an hour to think of the logic to find the mode of an array.I left out code for initializing the arrays, but all the values in the array are between 0-9. Check out my code below.
Code:
int mode( int array[], int size ) {
int i;
int count;
int max = 0;
int num = 0;
int mode;
[code]....
How do you find a mode in array? This is what i got so far. I put this after i sort the array
for (int index = 0; index < size2; index ++) {
//count[mode[index] - 1]++;
if (mode[index] == mode[index + 1]) // compare the first to sec array {
again++;
cout <<"This is number " << again << endl;
}
}
Im currently trying to find the mode of a vector through a map but am not sure how to do so besides the attempt ive made
void mode(vector<double>v)
{
map<double, int> map;

I've been working to make program to find the mode of sorted array. But the program didn't return the results correctly. Here is the code:

cin>>size;
int data [size];

I am writing code, which reads an input file (280 MB) containing a list of words. I would like to compute
1) total # of words
2) total # of unique/distinct words
3) mean/median/mode of word count (Link)
I managed to get done with 1) and 2), but my program crashes for 3). I am not quite sure whether there are memory issues or some bug in the code.
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <map>

I have to use numbers in my .txt file that are stored in an array. So i have to write a function to find the mode of the numbers in my array.
View 5 Replies View RelatedI've been wondering if there's a function or procedure used to know the current video mode. An example of how this was done in Pascal:
function VideoMode : integer;
begin
if (lastmode = BW40) or (lastmode = BW80)
VideoMode := 40
else
VideoMode := 80;
end;
I've been told "conio.h" has a lastmode function, but it doesn't seem to be supported in Dev-C++ and Visual Studio C++. Is there a Windows function to know the number of columns in the current video mode?
My code seems to find the mode of the array I input sometimes. Sometimes it gives me the wrong number or multiple numbers. It just all depends on what is number is inputted into the array. I don't know what the problem is. I tried looking online and editing many times and can't find the answer. Maybe I'm overlooking something or doing something wrong. Here's my code.
#include <stdio.h>
void readArray(int arr[], int length)
{
printf("Enter data:
");
[Code].....
Maximum: 15
Mode: 2
As you can see the mode is clearly not 2 and I do not know why.
