For the past couple days I've been making small improvements on a program I made to keep track of a battle count while playing a game. Mainly to reduce the chore of keeping track yourself while you're playing. But it still becomes a hassle to switch back and forth between the program and your game and I was hoping to be able to set focus to the game after the BattleCount method is called.
Currently I am importing a DLL that somebody recommended I use to make a ActiveProcess method that accepts a integer as a parameter which would set the PID but it doesn't seem to be working. The two methods are as follows.
private void countDownClick(object sender, RoutedEventArgs e) {
//Calls a method within my class that subtracts and adds battle values.
counter.CalculateBattles();
//These two change text on my WPF forms with accessor values from my class.
battlesWonText.Text = counter.BattlesWon.ToString();
battlesLeftText.Text = counter.BattlesLeft.ToString();
[Code] ....
This is the C++ code they told me to use to set focus to another application using a PID.
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
const UInt32 SWP_NOSIZE = 0x0001;
const UInt32 SWP_NOMOVE = 0x0002;
const UInt32 SWP_SHOWWINDOW = 0x0040;
[Code] ....
I'm simply trying to figure out how to set focus to a foreign program using their PID and a button click event in WPF. I'm using Visual Studio 2012 on Windows 7.
I was wondering if there was a possible way to change my c program into an application so that i can send the application to another person and not let the other person have access to my codings?
My reasons for asking this question: For the application i want to send there are secrets that are meant to be unraveled by gameplay but i dont want people to look at the codes and know everything.
Using mfc I have an application where I'm not allowed to use a mouse and alt+tab will be regularly used. Using alt+tab to come back to my application kills the focus in the view. Once my application comes back to the foreground how can I set the view as the focus?
I want to read the bar code using USB scanner without having the focus on text box using WPF. I have searched around online but not found related answers, I think it is the correct place to post my question.
I have MDI form which contains mutliple tabs and each tab has its own child form . When user presses ALT TAB from the from to other application its fine but when users presses ALT TAB back to my application it should keep focus on child form last time it was selected.
I have a strange problem in using C code. I want to move focus from one item to another in a keypress event (like keydown)in loop. But it move directly to the last item
Details: In the code segment, I am generating keypress event explicitly from code and want to move focus for number of items inside loop. Loop is working properly, but output is also generated after completion of loop and focus is directly coming on last item in list not showing intermediate movements. Voice output using espeak is generated correctly in each iteration.
Tryouts: I have tried to call a dilog box which take yes/no event by Btn press,that works fine. That means event generation in code is giving problem, it needs h/w intervention for keypress (As I understood)..
I want to highlight selected text in a wpf textbox while the textbox is not focused. In my application, my textbox never gets focus, and every key input is done manually. I was wondering if there is a way to highlight the selected text when the textbox is not focused?
I was talking to someone earlier about how to change the value of something from a function, and they said what was needed was to use a ** to change something, and was wondering if I could get a walk - through of what happens. I understand a single pointer well enough, but a pointer through a pointer is kind of confusing to me. Here is a simple example.
Code: #include <stdio.h> #include <stdlib.h> #define SIZE 5 int add(int ** TOP, int * stack);
int *stack = NULL;
[Code] ....
Why is it that when the program prints the address of TOP in main, it is different than the address of TOP in the function? Is it because it is a different instance of TOP because it is in the function? When I put the number on *TOP, and come out of the function back to main, it then says the address of TOP is the number entered into *TOP, and am not sure why. And the **TOP ++ at the end I am thinking it increments malloc by 1, therefore bringing the pointer TOP up to point at the next element, or am I completely off base there?
I use miracle library to work with big numbers. I defined a number for example X with 192 bit. at first X= 0 ;I want to change for example 3 bit of it to 1 randomly.as a example:
assume that X has 10 bit : X=0000000000 random numbers should be : 1000010001 1010100000 1100000100
I want to change the complexity of the code from O(n) to O(1) . So I wanted to eliminate the for loop . But as the sum "s" stores values like (i-1)/2 or (2*n-i+1)/2 so eliminating the loop involves tedious calculation of floor value of each (i-1)/2 or (2*n-i+1)/2 . It became very difficult for me to do so as I might have derived the wrong formula in sums of floors . Need Changing complexity from O(n) to O(1). Is there any other way to reduce the complexity ? If yes ... then how ?
I have this code which previously used the BigInteger library, however now I have GMP installed and I want to use that instead.
I have read the manual but I cannot figure out how to use GMP in this function without getting errors.
Here is the function:
Code: int lucas(long p){ //p is a number in the range of 2 up to 50,000,000, possibly bigger int s = 4; //previously assigned as a big integer int z; //used in the for loop below int M = 2; //previously assigned as a big integer for(z = 1; z < p; z++){ //this accomplishes the same as 2 to the power of p, and is stored in M M *= 2; } M--;

I can initialize variables using the gmp library, but when I'm trying to use the mpz_pow_ui() function I get errors because it wants me to use long integers, which are too small for the numbers I want to work with.
If I have an array of two columns that have the same values and I want to change only the third column how can I go about doing this. The values of the third column will change based on the values in one of the columns which I plug into a math equation. Also how come I can't show a double value in the array?
#include <iostream> #include <math.h> #include<iomanip> #include <vector> using namespace std;
I have a problem with my code which I can't work out:
double Mi = 200*pow(10,30); cout << " Enter accreted mass increment in solar masses "; cin >> dm; cout << "
[Code] ....
Basically the loop works, but gives the wrong results.
I need, at the end of the loop, to sort of "redefine" Mi as "Mi + Macc". I then need it to repeat the loop, and at the end add another Macc so that Mi becomes "Mi + Macc + Macc", etc.
I'm working on a project where we access a tiny premade database in order to log into and access another page. I got the log in part working right, but the last part of the project asks me to lock out the account after a certain number of failed attempts. I'm not sure if I need a method to do this or if I can do it right there in the button handler. I tried creating a method to use on the object that was already there, but I'm not sure if that's the right way to go about it. It says it locks the account, but the value in the database never changes, and I don't know why.
//from the login button handler protected void btnLogin_Click(object sender, EventArgs e) { bool IsFound = false; clsDataLayer dl = new clsDataLayer(); IsFound = dl.GetUser(Server.MapPath("~/AddressBook.mdb"), txtUserID.Text, txtPassword.Text); if (IsFound) { Response.Redirect("~/frmUpdateAddress.aspx");
i had created a client server program in MFC using TCP but by doing this the server can only work on one computer because you have to tell the client the ip address to connect to i.e
so i want to change my code so that i can use broadcasting but i found out that it only works using UDP. I tried changing the code but the error message "error with sendto: 10047" displays when i run the program.
that error means
Address family not supported by protocol family. An address incompatible with the requested protocol was used. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in sendto.
here is the code from server:
Code: WSADATA wsaData; WSAStartup(MAKEWORD(2,2), &wsaData); int port = 7171; if (param) port = reinterpret_cast<short>(param);
I haven't actually learned how to use arrays yet but I know the basic principle of it and decided to try and implement one to improve my code. I'm sure the thing is a bug ridden mess but I would particularly like to point your attention to the function sortDenomination(). Is what I am trying to do in the loop possible?
The reason why I want to do it this way and not with if statements for each denomination is because I can then easily apply this to the second part of the assignment which sees us split a double into dollars and cents and then process each separately. All I would have to differ for each is change the money_loop variable to include the last two denominations in the array.
Code: #include <stdio.h> /*Reads cents input from the user.*/ void getCents(int &read_cents) { printf("Please enter the amount of cents between 5-95:
I have a 10x10 array, initialized to all zeros. I create 2 random numbers for the purpose of guessing a position in the array. However, when I print the array, the 0,0 spot keeps shifting to match the 2nd random number generated. Is there something strange about the 0,0 spot?
Here is my code:
Code: seedrnd(); for (x=0;x<2;x++) { randArray[x]=rnd(10); } for (x=0;x<2;x=x+1)
[Code] .....
The 2nd to last print statement actually prints randColumn. The last print statement correctly prints 0.
I have a GPIO pin(GP4) on a microcontroller with a continuous digital pulse train coming into it. I am writing to it in C and do not have interrupts on this chip. I have been calling my input "#define inputA GP4". In C, I would like to be able to find the positive edge of a pulse and trigger the timer on it. I'm not sure if an XOR will accomplish what I need by storing inputA to another variable at some point. Would it be possible to accomplish this by writing code that acts like a positive-edge triggered flip-flop?
The other problem that I have is I need to be able to do this and not get caught in an infinite loop where I can still do other things sequentially with my code, if for instance, inputA goes to 0 and stays at 0 permanently. This means that my option of using while(inputA=0); is out of the question.
