Read/Write Process Memory Address Values?
May 30, 2010Ive 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 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?

2008 Express Edition: Attempted To Read Or Write Protected Memory, This Is Often An Indication That Other Memory Is Corrupt?
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.
Here is the programs I have installed:
Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)

VS 2008 Read Process Memory From An Open Program?
Dec 27, 2009I 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.

Dec 5, 2011I'm getting this error only on my laptop (so far) trying to get the local IP address. I've tried 3 different ways of getting the IP address and each one fails with the same error. This has never happened on my desktop machine but when I moved it to my laptop for additional testing I started getting the error and it further states "This is often an indication that other memory is corrupt". It does however retrieve the ip address but I'd like to get rid of the error. Here's my code and I might add that it never takes the catch ex path in my try-catch code it just stops on the error when running in the IDE.

Attempted To Read Or Write Protected Memory Again?
Mar 20, 2010i found out that the program wants to use a part of the memory that he may not use.In my case it only happens when i want to print something.In there i have a PrintPreviewDialog and add a PrintDocument.After that one is loaded it shows the document on the PrintPreviewDialog.Most errors that appear show drawing errors.So, how can i tell windows that the program may use the memory?
A friend of mine thought it was something like this:
[Security].Permissions.FileDialogPermission(Security.Permissions.SecurityAction.Demand) ]

Random 'Attempted To Read Or Write Protected Memory'
Feb 10, 2012I have a Windows application written in Visual Studio .NET 2008 in Visual Basic using the .NET Framework 2.0 A couple clients have been experiencing this very frustrating (but random) error "Attempted to read or write protected memory..." message. I've identified the code specifically when trying to create a new object from a VB6 DLL. [code] The new event of the VB6 object has no code. The error is very random, seems to work more than 99% of the time but every now and then throws an error. Same workstation and user can run the same code numerous times without any issues but eventually the exeption is thrown. I'm at a loss on this and it cannot be reproduced on demand.The VB6DLL is marked COMSelfReg in the MSI. The VB6DLL has not changed but the error seems to be new in the last few weeks. Reinstall the app and the VB6DLL does not resolve.

VS 2008 Error - Read Or Write Protected Memory
Apr 4, 2010I am working on an application that starts a few threads every second. The threads don't do much, and everything seemed fine. I monitor the number of threads running, and I have never seen it higher than 4.
Last night I started the app and this morning I had this.
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
The threads can make changes to two List(of Strings) and I had SyncLock's surrounding the code that did that. It has been running for several hours again and all seems well.
My question is that I found a place in the UI thread that was copying the list without the lock. Could that have caused the error?
how to debug something that isn't going to fail conveniently?

[Code]...
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.
