Jun 1, 2011I am working on vb.net win form. My task is display the file names from a folder onto gridview control. when user clicks process button in my UI, all the file names present in gridview, the corresponding file has to be loaded onto memory stream buffer one after another and append the titles to the content of the file and save it in hard drive with _ed as a suffix to the file name.I am very basic programmer.

Attempted 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)
Microsoft .Net Framework 2.0 Service Pack 2

C++ DLL Gives Attempted To Read Or Write Protected Memory?
Feb 18, 2011Have 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:

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

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:

Text In The Memory Address Of The Program And Write It Down In A Txt?
Jun 20, 2009I need to make a program for my school (I`m the principal), that reads the text in the memory address of the program and write it down in a txt. I couldn`t find a professional here in my city so, I already have the address numbers. For more information, I use VS 2008. I was trying to make one code to get the memory address, and after I succeed this, I'll make the correct program.
[Code]...
1. It only gets the first 4 bytes(is it?) of the memory address. I want it to get all of them.
2. I haven't discovered how to convert each byte(?) into a character. Is there a function for this?
3. When the program runs, after clicking ok on the MsgBox, it highlights the Next and debuggs:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
