I need a code that search's in a process memory a custom value. And get the address of that value. Its a simple question but with a hard answer. I've searched in all over the internet, but couldnt find any.

I'm trying to read another process's memory starting from mbi.BaseAddress to mbi.RegionSize using the function ReadProcessMemory, however I only succedeed to read 1 address at a time and it takes like forever to finish, the result being stored into a byte() variable, calling the readaddressmemory 1 million times instead of only 1 for example.

Read/Write Process Memory?
View 6 Repliesi have tryed so many times now so is there some one that can Read/ Process Memory in vb.net 08 ?
this is what i got
Dim help2 As Integer
Dim HP_Have As Integer = &H574
Label5.Text = ReadProcessMemory(proc.Handle.ToInt32(), HP_Have, help2, 4, 4)
Ive basically got 2 problems I need to solve.1) I am trying to determine if a certain process is running on the user's machine at the same time as my program.2) I am also then,if the process is running, trying to edit a specific memory addresses value. I have already found the memory addresses for the program, but how do I tell VB.Net to basically read the current value stored in that memory address, and then write a new value to that address
View 1 RepliesI 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.

Although generally it seems to work correctly, the problem is that for some memory values ReadProcessMemory is returning false, and GetLastError is returning 299. From what I've googled, it seems to happen on vista because some params of OpenProcess were updated. Anyone knows what this is about? And what values should I try? Notice that as they changed, I wouldn't want to know if it's VM_READ or so, I want to know exactly what the values are.

Read (search a value) in a non specific process memory. Write a value in the address found in the last function requested.
View 2 RepliesI am trying to edit the process memory of a game (Age Of Empires II: The Conquerers). I can edit the memory manually on TSearch and it works just fine. I want to this with VB.NET but have had no luck. Note: I am not doing this to cheat, I am just using this as a learning experience for changing process memory.

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.

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:

I need to create a way to dump the memory of a process to a file. And I don't mean a crash dump, I mean dumping the memory. In C++ you can use the function MiniDumpWriteDump.
Here is my code so far:
Public Declare Function MiniDumpWriteDump Lib "dbghelp.dll" (ByVal hProcess _
As IntPtr, ByVal ProcessId As Int32, ByVal hFile As IntPtr, ByVal DumpType _
As mydumptypes, ByVal ExceptionParam As IntPtr, ByVal UserStreamParam As _
IntPtr, ByVal CallackParam As IntPtr) As Boolean
Enum mydumptypes

A file is created, however when I looked inside the file with a hex editor, it was complete garbage. For a test, I opened notepad, typed in "Hello!", and dumped the notepad process. I could not find any strings in it, let alone the "Hello!" string.
mydumptypes.normal =
MiniDumpWithDataSegs= 0x00000001,
in c++. It wasn't what I wanted. Anyways, I fixed it.

Is there a way in vb.net to check whether new memory pages have been created inside a process(such as winlogon, svchost etc) For eg : if i there is a certain value that may change if new memory pages are created inside the process. Then i can compare the previous value and the new value (after pages have been created) and make it sure that new pages have been created inside that process.
