I would like to ask about editing proccess memory.For example,I would like to create some program for a multiplayer game which I play.How do I work with memory adresses and what are commands for it.
View 1 RepliesI am looking for a way to run a process form memory, without having any executable. The application will be kept inside a resource and will be extracted during run time. It should be then started as a new process. I couldn't find a solution that works also on x64

this is what im trying it fails
HANDLE Handle = OpenProcess(PROCESS_ALL_ACCESS, false, ProcessId);
BYTE btLdrLoadDll[] = { 0x8B, 0xFF, 0x55, 0x8B, 0xEC };
if (!WriteProcessMemory(Handle, (BYTE*)((DWORD)GetProcAddress(GetModuleHandle("ntdll.dll"), "LdrLoadDll")), &btLdrLoadDll, sizeof(btLdrLoadDll), NULL)) {
CloseHandle(Handle);
std::cout << "
Failed to write Bytes to memory. Press enter to exit.";
[Code] ....
an also using the right address like this fails
WriteProcessMemory(Handle, (BYTE*)0x77C64F9F, &btLdrLoadDll, sizeof(btLdrLoadDll), NULL)
Why the size of a process grows larger in size for lots of small memory allocations. For example, say I have this struct, which is 16 bytes (for a 32 bit build):
Code:
struct Person {
int iID;
int iAge;
char * pForeName;
char * pSurName;
};
If I allocate memory like this:
Code:
LPBYTE lpB = new BYTE[sizeof(Person) * 1000000];
Then my process grows to 16,48KB in size, which is what I expected. However if I allocate memory like this:
Code:
Person * lpPerson;
for(int i = 0; i < 1000000; ++i)
lpPerson = new Person;
Then the process grows to 78,656KB, which I don't understand.
Additionally, I was surprised to find a vector acts more similarly to the first example. This code:
Code:
Person temp = { 0 };
std::vector<Person> people;
for(int i = 0; i < 1000000; ++i)
people.push_back(temp);
Only increases the process memory to 16,892.
Well,I have a dat file which following format;

how i am using wxDev-c++ and i need to make.Tasks would include: use a class or struct variable, and create a program that can perform the following actions:

2. The display of the stored data.
3. edit the data.
Example of data: name surname age.

how to change a certain part of a text file? I want to +1 to a text file every time the user does a particular input. For example my text file has name << password << count . When the user logs in and choose option 1 the program will +1 to the count.
for e.g. Bob Bob123 1
when he logs in and chooses option 1.
it will change to Bob Bob123 2
What i'm trying to do is compile a text file to an executable, but the problem is that I want to be able to edit the resource file while in runtime, for example write something on a textbox, hit compile and get the executable file edited by the texbox.

public static bool Compile(string sourcefile, string exefile) {
CSharpCodeProvider ccp = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.dll");

Is there anyway I could do that?

I'm trying to change the time and id values and can't do it.I tried almost anything.
I'm trying to take a value from an edit box and display it in the edit box as hex. I'm using this code:
CString buffer;
int intbuf;
m_edit[5]->GetWindowTextA(buffer);
intbuf = atoi(buffer);
buffer.Format("%02X", intbuf);
m_edit[5]->SetWindowTextA(buffer);
If I include the last line of code here I get a stack overflow error. If I don't include it, I can run through the debugger and the buffer CString is converted to hex just like I want, I just can't display it because I get that error.
I am working on this project where I need to update an edit box every couple of seconds with a status and based on the status I need to change the color of the background to a particular color.I am able to update the edit box with the status but is clueless on how to update background color.I have read some info on line about this but is confused.This edit box is on a tab in a dialog. Also, on this tab is a Groupable List Ctrl.
View 2 Replies View RelatedI have this project for school where I basically need to write a program that will take any text file and convert it into html code.
string line;
int lineCount = 0;
while (!inFile.eof()) {
getline(inFile, line);
cout << line << endl;
lineCount++;
}
cout << lineCount - 1 << " lines of text read in this file." << endl;
I have this block of code to print each line of the text file into the terminal window and count the number of lines printed. But I don't know how to make it change a single character or set of characters to something else. For example, if a line of text begins with the number "1", I want to be able to change it to "<h1>".
I have a report that's generated by a piece of software, and (I'm assuming because it was intended for Linux/Unix) when I open to read it in notepad, it has a bunch of funky symbols in it, and incorrect line feed characters instead of returns that windows uses.
I looked at the txt file with a hex editor and can see all the hex codes for the symbols I want deleted. One of the symbols 0A.
How can I do a "find and replace" command but do it with hex codes? These symbols cant be simply placed into my code file because VS does not know how to interpret it.
I have made a datagrid in a WPF and added a button to add rows, here is the code for that:
this.itemListDataGrid.Items.Add(new TextBox());
Also, I have already got 3 colums in the datagrid pre-added by me, so when the rows are added I click on one to edit it and it comes up with error edit item not allowed.
Is it possible to edit the message map at startup instead of just having it set at compile time?
I'm reading some values from an XML file at startup. The menu options will be determined from what I find in there. But I need to assign those menu options to the message map.
I'm trying to create an edit box in a CView.So far, this is how far I've gotten:
With this code
Code:
// .h
CEdit m_MyEditField;
// .c
m_MyEditField.Create(WS_CHILD | WS_VISIBLE,CRect(40,40,500,Y+55),this,0x1552);
m_MyEditField.SetWindowText("this is my CEdit field");
As you can see, the edit box doesn't look like the ones in a dialog, which is what I'm trying to accomplish.
Is there possibly some other class I should be using for the edit box?Or another setting for .Create?
I am working on a program that will do several mathematical calculation and will store the data into a csv file.The one below is just a prototype version of this.In my program,I will store my csv file as (current-date).csv using time.
With this in mind,I want my program to first check does (current-date).csv already exists.If not,the program runs normally and output all the data into the csv file.
However if (current-date).csv already exists,I want my program to read and edit that particular csv file,by skipping part1 in my code(name,id N etc.) and start with prompting the user for numbers straight-away.
In other words, if (current-date).csv already exists,the user should continue outputting the numbers from where the user last left before last termination instead of outputting the name,date & etc into the csv file again.
Eg: if no=22, continue inputting values from no=23 till terminating the program again and storing the values correctly into the csv file.

#include <fstream>
#include <iomanip>

foreach (DataGridViewRow _row in Gridview_Output.Rows) {
DataRow dt1 = oDataTable.NewRow();
for (int i = 0; i < Gridview_Output.ColumnCount; i++) {

I have a tabbed dialog with a couple of Separate dialogs. I created classes of CDialog for each dialog. Im trying to get the text from the edit control from the tabbed dialog and it appears in a message box when I press a button on the main dialog.
Code:
myDialog test;
test.UpdateData(TRUE);
CString bla = test.m_edit1;
test.UpdateData(FALSE);
MessageBox(bla,bla,MB_OK);
The m_edit is a variable of CString for the edit box
it gives me a error and crashes.
How do I get the text from the other dialogs edit control?
