I've seen other people that have had this exception post on the forums, but none have had it happen like my situation. So I have a multi-threaded VB.net app that will have the protected memory exception occur while it's in the Thread.Sleep call.

Is the data not filling in because of the schema information not being retirieved? If so, is there a way around that?
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 :

View 6 RepliesI 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)

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.
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.

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) ]

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.

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.

I am trying to use a .dll in .Net that was written in C++ and was previously used in a VB6 application. I get the error mentioned above.

I'm currently using an unmanaged library written in C++ and imported via <DLLImport()> to access a dos virtual device driver, and that works fine. However, I'd like to be able to do this via my .NET application (without requiring an accompanying DLL). So, I'm trying to write to the virtual dos device using the kernel32 API and WriteFile, however I receive the error: "Attempted to read or write protected memory."
Mapping to the device with DefineDosDevice and CreateFile (also in the kernel32 API) works fine and returns a valid file handle, however when I attempt to write to the file it fails. I've even tried marshaling the data to an unmanaged block of memory using InteropServices (AllocHGlobal and StructureToPtr) and then writing it from there, however I still receive the same error.
I have written a code to take complaints and give that complaint a number automatically. For that i have created a "fno" named variable in settings.but somehow i cant change the value of it and i get this error "Attempt to access protected memory"
