Reading Memory From A Game?
Aug 10, 2010I'm currently developing a sort of community program that logs game things to their profile.
Let say... you are playing BioShock PC, you passed a checkpoint... but when you passed checkpoint the game needs to trigger a notify to my program that tells that the gamer has passed that specific checkpoint.
Is it possible to read it from the game's memory or do i need to modify the game's executable?
Reading Memory From An Application Don't Own In C++
Jan 26, 2012A couple of months ago, before I started learning C++, I made an application in VB.net that reads memory from an external program. This could be anything, from notepad to windows media player etc. I have been trying to find a way to do the exact same thing in C++, but to my suprise I can't find anything straightforward on the subject. All google comes up with is threads on several forums, where the general response is "Windows doesn't allow you to read from memory you do not own". But if it works in VB.net, it can work in C++ too.

View 2 RepliesReading Object's Memory Address?
May 4, 2009I'm trying to pass a business object from one WinForm to another WinForm for modification, and then repopulate the text boxes, etc. on the first form with the updated values.However, it seems that the object values set in the second form are not "sticking" when the code control returns to the first form.Is there a way to view the memory location of an object in VB.NET? I want to first make sure that the object variable on the second form is pointing to the same memory address as the object on the first form. Then I can take it from there.
In a separate VB project, I passed a simple object to a second form, modified the values, and re-displayed the object's values on the first form. It worked fine. In my real app, I'm passing an object that is a property of another object, which may be why it isn't working.SOLUTION: The problem was that I was using a DeepCopy() function that I found to simplify copying the properties of one object to another. Removing that function and manually setting the values to the passed object on the second form (ex. obj.property1
VS 2008 Reading Strings From Memory
Jun 5, 2010im trying to read "calculator" from calc.exe, now i found the mem adress where the value resides but i have a few problems
1) how many bytes should i read? im not just talking about calculator string but potentially any length string, i get different results with 4/8 bytes but same from 8 - 32 bytes
2) when i read i get a long value 27866486557179971 but how to convert that into a string
EDIT: ok by staring at the return value long enough i discovered that when i convert it to hex it spells "calc" backwards, same for all other strings, i could build a working converter based on that knowledge but now what bugs me is where is "ulator" or the rest of the string, the most i can get is always 4 letters
EDIT2: oh nm that, by moving memory adress a step further i get the next letter along with 3 previous ones and still backwards but i can work with that
ok so now next step would be making a search function for which i need to find out the range of memory to scan, anybody know how to do that?
VS 2010 Memory Reading / Offset Usage?

VB - Pointers, Memory Allocation And Reading Writing Data?

View 10 RepliesAttempted To Read Or Write Protected Memory / Often An Indication That Other Memory Is Corrupt
May 22, 2007Im 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?

View 1 RepliesThread And Memory Leaks - Memory Usage Jumps About 1000k And It Never Goes Back Down
Apr 17, 2011I've noticed that every time I start a new thread in my program, the memory usage jumps about 1000k and it never goes back down. I have ensured that the thread is no longer running, and only one instance of my worker thread is ever running at a time. I am using ThreadPool.QueueUserWorkItem and ASyncOperation to get stuff done. The program starts using a Sub Main in a module that uses STAThread; I read that using STAThread instead of MTAThread makes it impossible for the Garbage Collector to get in and consider objects for garbage collection. However, when I change the STAThread to an MTAThread, the WebBrowser control in my frmMain cannot be instantiated.
I get this exception:
Code: An unhandled exception of type 'System.Threading.ThreadStateException' occurred in System.Windows.Forms.dll
Additional information: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment. I do threading with the WebBrowser control, so will using MTAThread fix my problem? If so, how should I partition my code so that the WebBrowser control won't be affected by the above exception? I call the thread repeatedly with a timer (although only one instance ever runs at a time), and my program's memory usage starts at about 5000k and can jump to 300,000k+ depending on many times the thread needs to be called.

May 27, 2009I 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.

.net - How To Deallocate Memory
Nov 4, 2010I have the following method for looping through a table, changint some values in every row and saving the chages back to the database. To make things go faster I am fetching data in sets of 10,000 rows. This is a large table with over 25 million records in it.
The problem is that my application doesn't seems to be releasing any memory. I have tried redeclaring the records variable to nothing or explicitly caling the garbage collector but the memory stays there.Runnning the built-in VS10 profiler I can see that the culprit is the system.linq.enumerable.tolist() method which takes up over 98% of my memory. How do I release that memory after the call to saveChanges?
