I am trying to make a dps meter for a game, and basically would like to know how to read the memory fields (NOT WRITE).This can be done in VB(Preffered), but I am also semi useful with C# so it can be done in that as well.
View 1 RepliesI've been scouring Google looking for a solution to my problem, but I can't seem to find anything so thought you guys might know a way of solving my problem.Im writing a little program which needs to change a few different memory address variables of a specific process.Does anyone know how first of all I can detect if the specific process is running on the user's machine, and then how I would read the value of the memory addresses, and write to them also.
View 3 RepliesI need to make a program for my school (I`m the principal), that reads the text in the memory address of the program and write it down in a txt. I already have the address numbers. For more information, I use VS 2008.
I was trying to make one code to get the memory address. So, after I succeed this, I'll make the correct program.
The code I made(adapted from [URL] returning-0 ):
Public Class Form1
Private Declare Function ReadProcessMemory Lib "kernel32" (ByVal hProcess As Integer, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Single, ByVal nSize As Integer, ByRef lpNumberOfBytesWritten As Integer) As Integer

I want to be able to read and write the process memory of Firefox for a game on facebook(It's kind of like cheating only you can't cheat, nothing stays permanent.) this is just for fun. The game is called happy fish aquarium and you raise fish in the game and it's just really addicting. I found a program that reads process memory and lets me change certain values in happy fish aquarium so I can make my fish tank look different or whatever. But if I reload the page it will of course go back to the original state because the fish tank's memory is held online. The point is, I just want to make a program that can read the process memory from Firefox from a certain range and bytes. like 4 bytes and a range of 00400000 to 7FFFFFFF. Does anyone know how I can achieve this? Please note, this is not for cheating purposes in any way whatsoever, it's simply for visual fun(visual meaning only I can see it). What I want to do is the same as using the add-on firebug in firefox to change the html on a webpage.

I'm trying to get a string from a byte array previously read from memory
i can get the string like this
dim mem as string= ASCIIEncoding.ASCII.GetString(memory) or dim mem as string= UTF8Encoding.UTF8.GetString(memory) but when i try to concatenate this with another string i get a strange result dim result as string = "this is you memory string " & mem & " problem string" no matter what comes after mem in the concatenation it seems like it is not there when in fact it is because when i try this (mem has two chars in it) dim result as string = "this is you memory string " & mem(0) & mem(1) & " problem string" problem string appears so what i assume is that there are some vbCrLf chars in the string after reading (or is it from the conversion?)
Im getting a problem with one of my programs I have made in visual basic.NET where it gives me a memory error when i debug the program in the IDE. the exact error is this: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". My program basically has a few forms with text fields on that get their text values from an access database on the same hard drive. Im wondering if im doing something wrong because my program just seems to eat up memory whenever it does anything. For example I have one form that has a combobox on it and when you change the drop down list selection it retreives a few strings from the database and puts them into the relevant text boxes, if you keep changing the selection then the memory usage (in task manager) just keeps going up and up. occasionally I get the error mentioned above when debugging but in my built version of the program it throws an exception everytime the memory usage gets past 49K.
Also I noticed when debugging in the "immediate window" frame I get the following message often:A first chance exception of type 'System. Invalid OperationException' occurred in System.Data.dll...Do I need to somehow be "releasing" the memory that is used to gather data once it becomes redundant?
I am using the following code
This error occurs :

I cannot use Visual Basic 2008 at all. When I go to "new project" and choose "Windows Form Application" I get this error.I have tried multiple uninstall/reinstall with no result.A microsoft reply to this suggested that I needed: " .NET Framework 2.0 Service Pack 1 " I checked, and I did not have the .netframework 2.0 service Pack 1.
When I tried to download and install the above from Microsoft.com, the istaller said that "it was not allowsed" and I was not able to install the service pack 1.
I tried Uninstalling net framework 3.5, 3.0, 2.0 and then reinstalling .netframework 2.0 sevice pack 1; then reinstalling Visual basic 2008 express edition. At the reinstall of Visual basic 2008, .netframework 2.0 sevice pack 1 is unistalled by .net framework service pack 2.When I check the foruims for simiar problems, the formus are mostly for Visual basic 5.0, or other programs that I do not have.
Here is the programs I have installed:
Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)
Microsoft .Net Framework 2.0 Service Pack 2

I have two forms, Form1 and Form2. Form2 has a button to show OpenFileDialog. I call Form2 from Form1 by a button. My startUp Form is Form1. When i start debugging, i press my Form1's button to show my Form2, it shows, but when i click On Form2's Button to show OpenFileDialog it is giving me exception that
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
When i set my startup Form to Form2 and click Form2's Button to show OpenFileDialog then it shows!
I'm trying to fix a problem that is just killing my program's efficiency. When I run it, it starts out at maybe 10M of RAM, but it gradually increases. Within 20 minutes, it can get up to 700M of RAM. Now, when the program is restarted, all of this goes away and starts anew, but restarting the program every so often is a very loose solution. Here's what my program does: there's an array in which many (anywhere from 500-4000 or so) links are placed. I have a webbrowser that navigates to each of these and does an action on them, then moves to the next page. For example: [Code]
And all of the actions work perfectly, but the memory exponentially increases, resulting in a crash if left on for too long. I've searched Google and all I've found is that that's not the actual usage, and that if you just minimize it and maximize it again it will go down, but it did not when I tried it. Why is the memory increasing so much like that, and is there any way to fix it?

2) To access the Chat Program one has to put in ones Username and password in a Login Form.
3) TextBox1 = Username TextBox2 = Password
4) One clicks the "Log In" button.
5) HERE is the problem. I do not know how to check if the specific username and the password are correct. I have a file called "Users.dat". In there every valid Username(marked with a *) and it's Password(marked with a #) is contained e.g.*Username#Password.
I want my "Log In" program to check if the Username matches one of the usernames and if the username is found in the file, if the password provided is the same as the one standing behind the Username in the file.
6) If both the Username and Password are valid, the Chat Programs shows up.

Have written a simple C++ DLL to provide info back to a calling VB.Net application in a structure passed over to the DLL from VB. On return the structure contains the data from the DLL but gives an error. Have tried changing the field types in C++ (I'm not strong at all in C++) but still getting error. Have provided the two sets of coding for the C++ Dll and the VB.Net program:
