in the following code how would i set a txt file up to where i can have say name = whatever in it and the program will find it and set it to the corresponding global value.
I started with C# 2 days ago, but i have made 3 "games". Its something like Cookie Clicker, very simple and very easy.
But I have problem with saving the game. I want to save values of variables to text file when i click on button, and when i click on another button i want to values of variables load. Just simple save system. How it works and so.
Lets say i have an array with the values 1, 5, 9, and 3. is there anyway to make this so i can have an int with the value 1593 based on those numbers in the array?
This function below takes a pointer as an argument. What I expect to happen is, since expr++ has higher precedence than *expr, that is, the primary expression operators have higher precedence than the unary operators, pointer arithmetic should occur where we increment to the second address pointed to by dbuf, and then we should dereference the value at that address. Given that logiv, when i print dbuf[3] it should print the value pointed to at the 4th address in dbuf. However, the value it returns is 0x0 not 0x3. Why doesn't it dereference the value 0x3?
I am trying to create the lparam for the WM_KEYDOWN message. I know this is the C programming forum, but my code is standard enough to apply here. According to Microsoft, the lparam must be formatted like this : lParam The repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown following. Bits Meaning 0-15 The repeat count for the current message. The value is the number of times the keystroke is autorepeated as a result of the user holding down the key. If the keystroke is held long enough, multiple messages are sent.
However, the repeat count is not cumulative. 16-23 The scan code. The value depends on the OEM. 24 Indicates whether the key is an extended key, such as the right-hand ALT and CTRL keys that appear on an enhanced 101- or 102-key keyboard. The value is 1 if it is an extended key; otherwise, it is 0. 25-28 Reserved; do not use. 29 The context code. The value is always 0 for a WM_KEYDOWN message. 30 The previous key state.
The value is 1 if the key is down before the message is sent, or it is zero if the key is up. 31 The transition state. The value is always 0 for a WM_KEYDOWN message. ( WM_KEYDOWN message (Windows) )^ I'm troubled by setting it into the 32-bit value, and I get confused about what exactly happens when the logical or and the bitshift operators are used. I tried to use them below in my code by looking at Stack Overflow for setting a bit. I also don't know how to test for the endianess of my system, and how to handle it if it's big endian or little endian. Here is my code so far :
I need to set a function to a variable of some kind. Then later in the program it needs to run the function that is set to the variable. The variable doesn't need to change after it is set to a function, it just needs to be able to be set to a function. So maybe I don't need a variable? What do I do? :3 Is this even possible? :o
Example: if (PosRampYes == 0) { SomeVariableOrSomething = FirstFunction(); } else { SomeVariableOrSomething = SecondFunction(); } //later: SomeVariableOrSomething; //so if PosRampYes is set to 0 then this line would run FirstFunction()
I declared a pointer in main with value 0, so I want to change its value so that it points to other variable from a function, I guess the function creates a copy of my pointer that's why whatever I do within function doesn't change the real direction of the pointer in main. I've been trying something like this:
#include <stdio.h> void redirectionate(char *str, char *ptrCopy); int main() {
I created a WinForm app in C# using VS 2013 Express.
I added code to create a Global Hot Key on the main form. This works fine. My hot key is Ctrl-T. I can press the hot key and make the main form show and hide.
Then I created a second form (ChecklistForm) and now I want to press ctrl-T and make that form show and hide. I do not need the main form to do this any more. I just used the main form to test my Global Hot Key code.
So I'm having trouble getting the second form to respond to the hot key. When I put a break on the WndProc(), there is no break.
namespace ChecklistFSX { public partial class MainForm : Form { [DllImport("user32.dll")] public static extern IntPtr FindWindow(String sClassName, String AppName); private IntPtr thisWindow; private GlobalHotKeys hotkey; public MainForm()
Basically the whole purpose of this program is to prompt the user to use a calculator. Choices 1-6 are valid, but I want to set it up where selecting any other number outside of 1-6 to be Invalid, and will display an 'Invalid Choice' message, and then go back to the main menu.... The main program does work properly, it's the 'Invalid' setup that is giving me problems
Code:
#include <iostream> #include <iomanip> using namespace std;
I am trying to find out when using float in a calculation how to set the number of decimal places. For example my code below
Code: #include stdio.h> int main() { float x=123.0;
[Code]....
This returns an answer 8487.0000 I would like it not to show all the decimal places. However if the sum has decimal places I would like to select the number of decimal places shown.
I am having problems with setting up a menu as a function. The point of the menu is to display a list of 4 options and the user is supposed to choose one option and then the program will run. I am having trouble understanding how to display the menu once I run it because it is not working.
#include <iostream> using namespace std; int menu(int ans); // function declaration for menu void draw_triangle(int size, char ch); //function declaration for triangle void draw_downtri( int size, char ch); // function declaration for upside-down triangle void draw_diamond(int size, char ch); //function declaration for diamond
I tried to write a little bit of code to set all bits within a signed int with exception to the MSB, yielding the greatest max positive value. The odd part is that it works for shorts ints, and longs, which are 2, 4 and 4 bytes respectively, however long longs, with a size of 8 bytes, simply yields -1, which would indicate that it failed to clear the MSB. Heres the little segment in question:
my::numerics is just an exercise- its thoroughly tested and I'm certain thats not the issue.
For shorts, ints, longs, this yields the maximum value. However, when I use it on long longs, the output is 0xFFFFFFFFFFFFFFFF, i.e. ~0. Obviously this means the maximum value for unsigned long longs, but -1 for signed long longs.
I'm trying to create a program to balance a checkbook. In the program, I want to be able to list the deposits and withdrawals individually, as well as the total deposits, total withdrawals, beginning and ending balances. I am trying to set up two different arrays to do this, but how to set them up the right way.
Code: //checkbook.cpp //EmilyBattaglia //final project part C #include <iostream> #include <iomanip> using namespace std; int main(){ //declare variables
I have a MFC dialog project, I move all the icons including the IDR_MAINFRAME icon into a resource-only DLL, so there is no icon embedded in the executable file. In the dialog initialization, the dialog loads the icons using LoadIcon(hResdll, MAKEINTRESOURCE(IDI_MYICON))). The icons shows correctly on the dialog.
But in the Windows Explorer, the icon of the .exe file is not the icon of IDR_MAINFRAME, I check the resource file in the resource-only dll project, the ID number of the IDR_MAINFRAME is the lowest one of all icon ID numbers. I also try
