I'm trying to get the current time for a game and print that to the games chat window. I'm already injected into the process do I don't think I need ReadProcessMemory.
The value i'm trying to read is the game hours 1-12.
//doesn't work
byte time_hour_get ( void )
{
return *( byte *)0x00B70153; //the address to the memory containing the
}
addMessageToChatWindow((char*)time_hour_get); -> when I call this function it looks like s , . I want it to return the integer value like cheat engine. I used byte when scanning for this address
In the code below. I believe I am returning the memory location of the value I am looking for. How can get the value?
main.cpp
int choice = 0; PlayerMenu *newPM = new PlayerMenu; File *file = new File; // Menu for loading, creating or exiting the game choice = newPM->menuChoices();
PlayerMenu.cpp
[Code] ....
I am not sure how to deference the value so I can get at the value instead of the memory location.
The results of my code is supposed to be very simple: return the 2 integers and then their sum. However, it's doing returning the first value, then an address in memory(rather than the 2nd value), and then the 2nd value(rather than the sum). Here is the code:
Right now im creating a program that use xbox inputs and then send out keyboard functions using sendInput();
It works fine, but now im creating a system wich lets the user of the program change the settings in a textfile. Wich will then change what the controllers bindings are.
example, if settings.txt says: Y=button(0xIE)
i want the program to know that when xbox button Y is pressed, execute a sendInput function to the Key: A (0xIE).
The problem is that the virtual keycode (0xIE) i take from the settings.txt is stored as a string (lets say it is stored in string Y_event)and input.ki.wScan has to be of type BYTE. i made a function wich changes string into int. (because input.ki.wScan seems to be fine getting a int?)
int stringToInt(string insert) { char back[20]; for(unsigned int e=0;e < insert.length();e++) { back[e]=insert[e]; } return atoi(back); }
but when i run the code nothing happend...
In the code i have a function wich executes the keypress: void pressbutton(int key, int time)
when i send in the converted string it doesn't work but when i send in: (0xIE) it works.
pressButton(stringToInt(Y_Event),50) // doesn't work pressButton(0xIE,50) // works
Basically it has to do with the byte ordering in a binary buffer vs the typing of a variable used to hold it.
To give you an example, if I have a buffer (say of indefinite length), and a ptr "ptr" pointing to a byte in the buffer (say, C0), such that if I open the buffer in a binary viewer it reads like this: Code: C0 DD FE 1F Such that this is true:
Code: /*ptr is uint8_t*/ *ptr == 0xC0
Then I do this:
Code: uint16_t var; var = *(ptr+1);
I would expect the result to be:
Code: DD FE /*56830*/
Though if I print that out with:
Code: printf("%u ", var);
It'll print:
Code: 65245 /*(FE DD)*/
Now obviously it's byte swapped, but what is causing that? I'm assuming if I just stream that out to a file byte by byte it'll be fine, so it's something with the 16 bit data type (also have seen this issue with a 32 bit data type, where all 4 are in reverse order). Is there any way to 'fix' it except bit shifts & masks?
I basically want to create a save editor application that will enable people to alter various values in the save by clicking on releveant buttons and then also for the editor to auto update the checksum when changes are done.
The save file is in hex so from what I can gather I would need to create a button to open the file using 'open file dialogue' and then read the file into a byte array so that the values can be called at any time when a particular butto is pressed and the application will then seek to the point in the file to make the required changes.
I have an application that has its own embedded web server. I am trying to add jQuery/Ajax file upload capabilities to the application however, I am running into issues getting the posted file. The jQuery/Ajax portion is similar to this method here. Due to the way the webserver was written (its in a dll and I do not have access to the source), the posted file comes in as a byte[]. If I try to save the byte array directly to file using:
File.WriteAllBytes("path", ByteArray)
I end up with a corrupt file that I cannot open. I believe this is because the byte array also contains the posted file header info (Content-Disposition, name, filename, etc.). If I view the contents of the byte array using:
System.Text.Encoding.Default.GetString(ByteArray) the header info can be viewed as: ------WebKitFormBoundaryQfPjgEVpjoWgA5JL Content-Disposition: form-data; name="0"; filename="someimage.png" Content-Type: image/png ‰PNG
Based on the selected file size and the size of the byte array, the entire file is in the byte array. How can I go about extracting and saving the posted file from the byte array?
to read byte from the serial port.This function is part of the DLL that came with the chip(FT2232D) I am using on my board.I want to use the function to read a byte from the serial port and then send the value to the Graphic user interface.Unfortunately I was unable to get the expected value on my GUI.If I send for instance 40,what I get on the GUI are letters instead of the number 40 or at times the GUI will not even respond.Below are my lines of code I used to read the byte from the serial port:
The following instructions are executed whenever the CHECKBOX is checked
Trying to write very simple code to read a 4 byte int from a file.
code:
int tester; FILE *fp; fp=fopen("/home/bdluser/skeleton.blx","rb"); fread(&tester,sizeof(int),1,fp); printf("tested 1 byte read should be 1: %i",tester);
I have tried editing the binary file....it outputs similar large numbers
I am using print/sprintf with a "%i" format string. Works fine if the input is indeed a 32bit integer. But how can i put in 8/16 bit (ie short & byte) 'integers'? If i just throw them in, they are always taken as unsigned, as the topmost bit/s is/are casted to zero... [URL] ....
I'm trying to understand why a conversion from a byte array (unsigned char) to a double works when done one way and not antoher.
In the example code I test by hard coding an unsigned char array of the same bytes that the double consists of.
When I copy the bytes to a long long and cast to double the result is not the original double but if I use a struct the bytes can be set and the conversion happens.
Seems to me that both ways should work. I'd just like to know what is going on with the "struct way" that makes the conversion correct. I see in debugger that the bytes in memory are the same for piAsLong and u.bytes.
My compiler is VS 2012 and a long long and double are both 8 bytes (tested with sizeof). This is learning activity only.
Code: #include "stdafx.h" #include <iostream> #include <iomanip> using namespace std; union { double d;
I'm having trouble reading a block of bytes into a vector of short ints. My code is as follows:
Code: FileStream.seekg(2821); vector<short> g_Data; int iter = 0; g_Data.reserve(maxNumOfInts);
[Code] ....
The relevant block of data starts at offset 2821 in the file. Every two bytes are a signed short integer. What's odd is that it's giving me the correct results only part of the time. At offset 1052421 and 1052422 there are two bytes 40 and 1F that are correctly read in as 8000, but at offset 1052415 and 1052416 bytes 88 and 13 are read in as -120 instead of 5000.
I don't see anything wrong with my code, though, unless I'm misunderstanding completely how to convert an array of two bytes into a single float. Is my method correct? Better still, is there some way to just convert en mass an array of bytes into a vector of signed short ints?
I'm trying to parse some binary data in the form of an array of bytes and I've come across something that is confusing me related to the representation of data as chars versus ints. It's a bit of a long story, but the byte array contains a mixture of character data and integer data which I' having trouble unravelling. The problem seems to arise from the issue below:
So basically here I have a menu in my C program and if I were to select option 2, I would enter a string up to 30 characters and it would output each block of 16 bytes should be shown which contains a character in the requested string. However, when I compile and run the program and search for the string, nothing happens. what I may be doing wrong?
Code:
else if (select == 2){ printf("Enter a string of up to 30 characters: "); scanf("%s", &userstr); //Compares both user's string and file string for (i = 0; i < size; i++){ if (strcmp (buffer, userstr) !=0){
I am trying to store each char of a string(string a ="1100") into a byteArray ( byte[] byteArray = new byte[4]. its not showing any error but its storing like below:
I don't know why but its replacing 1 with 49 and 0 with 48.what am I doing wrong or how to do this?
my code is as below
byte[] byteArray = new byte[4];)/> int binArrayAdd = 0; string a ="1100"; foreach (char Character in a) { byteArray [binArrayAdd] = Convert.ToByte(Character); binArrayAdd++; }
i need to search for a keyword in a binary(.raw)file and have to extract the characters(until a '&' character is found)that immediately following the keyword .
In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.?
