VS 2010 Read/Write Program Memory Addresses?

May 30, 2010

I'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.

Attempted To Read Or Write Protected Memory / Often An Indication That Other Memory Is Corrupt

May 22, 2007

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?

2008 Express Edition: Attempted To Read Or Write Protected Memory, This Is Often An Indication That Other Memory Is Corrupt?

May 27, 2009

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

[code]....

All the security updates and hotfixes for Widows XP.

C++ DLL Gives Attempted To Read Or Write Protected Memory?

Feb 18, 2011

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:

API_NKCdll.h file

namespace API

{[code].....

When this VB program is run the DLL crashes on the Interface_Link_ ConfigOperationTest(objInfo)

instruction with:- "Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

the values in objInfo have been altered by the DLL correctly.

Attempted To Read Or Write Protected Memory

Dec 5, 2011

I'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, 2010

i 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) ]

DLL Import - Attempted To Read Or Write Protected Memory

Dec 29, 2010

I'm stuck at dll imports with the c++ dll. Here is the function in the c++ dll that I want to call from my VB.net code.
bool LoadNewTestPlan(const char* szPlanFileName=" ");

I've tried many ways in my VB.net but always getting the error : "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

I have tried passing in byte(), Marshalling with LPStr, SafeArray and nothing works. Here is the example of my code code within the module
<DllImport("HPVKIfc.dll", EntryPoint:="?LoadNewTestPlan@HPVKIfc@@QAE_NPBD@Z", CharSet:=CharSet.Ansi)> _

Random 'Attempted To Read Or Write Protected Memory'

Feb 10, 2012

I 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, 2010

I 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?
