MAS and Attempted to read or write protected memory.

I'm experiencing an unusual system error using Mobile Application Studio enviroment (CRM Release 2007 / 5.0 SP 09). As soon as I run the MAS, open a Change List and say edit a tile, tileset etc... the application crashes and the system displays a dialog box with the error message:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt".
How can i resolve this issue in our mobile application studio?
Thanks in advance
Eddie

Hello Eddie
The mentioned error is generic and could be because of several reasons.
If you try to edit any BOL Object designers or Code windows from MAS Startup Page/Find Results window throws an error u201CAttempted to Read or write protected memory. This is often an indication that other memory is corrupt", So it is always recommended to expand the Business Library node manually after opening the MAS and continue with other Modeling/Development tasks.
But if you are not modifying or editing any of the BOL objects, then it must be becuase of some other reason. In such case, can you please provide more detailed steps for the crash to occur.
Best Regards

Error "Attempt to read or write protected memory" in MAS

Hello,
I am always getting the error message "Attempt to read or write protected memory. This is often a indicator that other memory is currupt" as soon as I try to add a new Method to a BO. What I do is
1) Open BO in Code Mode
2) Open Tab "Document Outline" ; right click on Method and "New.."
3) I enter the Method name i desire "Z_CPB_RetrieveStockInfo"
4) I enter the specific signature i need "Public Function Z_CPB_RetrieveStockInfo( ByRef Sfmara As String) As Object"
5) I press ok and get the error message in the first popup.
6) I get another error Popup "Cannot open the code window. Reason: The object may have been deleted from the Changelist"
The method "Z_CPB_RetrieveStockInfo" listed in the "Document Outline" Tab below Methods, but not in the selection box above the code. If I restart MAS I can see the method in the code and in every selection box. It is also possible to enter the code into the method, but as soon as I saved and restarted the machine, the code is gone and the method body is empty again.
Does anyone know what's going wrong?

Andreas

"Attempted to read or write protected memory" error in loading a report.

Development Environment
===
Windows XP
Visual Studio 2008 Pro; with Crystal Reports 2008 for Visual Studio

Windows dll
Crystal Reports Runtime SP2 (12.2.0.290)
Deployment Environment

Crystal Reports Runtime SP3 (no be confirmed)
I have created a windows dll with a form with a reportdocument, that loads a report (CrystalDecisions.CrystalReports.Engine.ReportDocument).
Then we circle through the report setting every table location to point at a specific ODBC and database.
The Dll can do this process several hundred reports in a day. However a small number (less than 10) of these have the following error:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
This is normally occurring when the reportDocument.Load function is called. But also happens when going through the setting of table locations: [myTable.ApplyLogOnInfo(TmpTableLogOnInfo)
The dll is called via COM interop and so i have checked "Register for COM interop".

1) Get to SP 3:
for dev computer:
https://smpdl.sap-ag.de/~sapidp/012002523100007123572010E/cr2008_sp3.exe
Recompile the app after SP3 is applied.
for SP3 runtime:
MSI

MSM

(You will have to uninstall SP 2 runtime before installing SP 3 runtime)
2) Do not use "Any CPU". CR2008 is only 32 bit anyhow so use 32 bit.
3) Make sure you are using .Close and .Dispose once you are done with each report object

AccessViolationException: Attempted to read or write protected memory.

Hello all.
The application that I am working on has a Oracle DB 10g and we want to migrate the DB to 11g (11.2.0.2). The client OS is a Windows 7 x64 and the application (which is an x86 app) is a hybrid between .NET and C++(COM components). The .NET part is using ODP.NET components and the C++ part is using ODBC drivers (oraclient 11.2.0.1 - x86 version).
The problem is that the application works without any problems with the 10g DB but when switching to 11g we get an exception. Basically, we have a try { call COM component } catch(Ex ex) {...} and the Exception ex is a AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I debugged the C++ part and this strange thing happens: the component opens the connection (using a connection string like this : "driver={Oracle in OraClient}; uid=... pwd=.. "), executes some queries, and on one query (which is the same as the last ones - just some selects), when the data is processed (by data I mean a integer ID), the exception is thrown in .NET code. I was able to enter in afxdb.cpp and it looks like the exception is thrown when GetData method is called. I looked over the ID's from previous queries and the data passed to GetData method is about the same (I mean the fieldtype, index, len, SQL type).
As solutions I tried:
-set "Statement Cache Purge=true" => same effect
- install a instantclient11_2 basic and ODBC drivers (for 11.2.0.2) but I could not connect to the DB (I could find the new drivers in registry WoW64Node/ODBC Drivers, put the location in PATH in front of the other OraClient and replace the OraClient with the name in registry in conn string) => Specified driver could not be loaded due to system error 127.
- tried to see the Marshal.GetLastWin32Error() => returns 0.
Any ideas? :D

The select clause that causes the problem is actually a select over a view. I replaced the select * from MYView with the actual select clause (with inner join) and the issue disappeared.
Any ideas? :)
Solution:
Looks like the view was written using INNER JOIN stuff. I replaced the code from the view with a simple select like this (inner join free):
select table1.col1, table2.col2, table3.col2, from table1, table2, table3 where table1.col1 = table2.col1 and table1.col1 = table3.col1
Some questions still remain (even if my issue is partially solved):
- why was it working on 10g?
- why this particular view crashed? (there are other views that use inner join and don't cause this)
- why was it working when using the full select (with inner join) and not working when selecting over the view?

Attempted to read or write protected memory error

Hello,
I am using the .Net library and occasionally I get a System.AccessViolationException,"Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Currently it is occurring when trying to initialize a TypedTPINIT object (this has happened in other places before and we just retry the request as a work-around). I set the size equal to the password length + 2 and the constructor for TypedTPINIT throws the exception after making the call to tpaloc. I have code that catches the exception and tries again up to 5 times before bubbling the exception up the chain. Once this exception occurs, no calls can be made to tux, they all throw the same exception. Once the application is closed and restarted (restarting the win32 process), everything works fine with the same data. It will work for a day or two and then fowl up again, seemingly at random. I am unable to reproduce the error at will, we just see it popup now and again, but closing the process and restarting it makes it go away for a while.
Any idea why this exception is happening?
I tried taking the .Net library out of the question and make the call to tpalloc myself using p/invoke and the same thing happens, but not every time.
I appreciate any help you can provide.
~Jason

Hi Jason,
I would suggest using a memory access checking tool like bounds checker, electric fence, or the like, although I don't know what's available in a .NET environment.

Attempted to read or write protected memory error on reportdocument.load

Reportdocument.load causes "System.AccessViolationException: Attempted to read or write protected memory" error.
The error is not consistent. Sometimes a report will print. Sometimes a report will error.
I am at a loss as to what to try.
I have uninstall the app, reinstalled the app, uninstall and reinstalled .NET frameworks, Visual C++ runtime, etc.,
reworked the code to try to capture the error. Nothing helps. Application crashes with Unhandled exception.
Attempted to read or write to protected memory.
Has anyone been able to resolve this issue?

Hi Mary,
What happens if you set your project to use 4.0 framework?
Anything else in the Event Viewer to show an access violation?
Have you tried updating the printer driver to one that is supported in the Framework? I find most legacy printers tend to use the old DEVMODE structure and not the Framework. Try using the printer off the Window CD rather than the Manufacturers driver.
Is your app doing "Report Bursting"? In other words sending multiple reports one right after the other with no time between?
Are you using any legacy UFL's? Try renaming u2lcom.dll if you are not using them. If you do you'll get an error in formula.
Are you using try/catch in your code around each CR API? It may catch something more for you also.
AND, can you try a C# project, some thing very simple also. I've of issues in VS VB that do not show up in other dev languages. Neither Microsoft or SAP can figure out what the cause is.
Thank you

For the VS 2010 project if the .exe inside the debug folder (unless you are compiling for release then the release folder) is executed outside of VS 2010 does the same issue occur?
Also VS 2010 I believe required some updates. Perhaps this tool
VersionInfo (Version information about your Visual Studio 2010 installation, and how to keep it updated to the latest) could provide if there are any issues with your VS 2010.
On the other hand what originally occured with this project? It was created on VS 2010 and never worked then a copy of it was used with VS 2012 and all the sudden it worked? Or for some reason on VS 2010 it was working then one day suddenly memory issues
began occuring?
If the "one day suddenly memory issues began occuring" was the issue then that would be the day to get assistance. As anything could've happened that day that possibly could've been traced rather easily where however much time has gone by now and
whatever else has been done with that system between then and now may make that extremely difficult to impossible.

Attempted to read or write protected memory in SAP 8.81 PL5

Hi
I seem to be suddenly getting lots of 'attempted to read or write protected memory' in an application I am writing using the B1DE
It seems to fail either when connecting to SAP or when initialising a recordset command
I have tried the usual tricks -
delete SM_OBS_DLL folder
reinstall client
reinstall DI API
I am on SAP 8.81 PL5
It's causing me real problems as I can hardly run my vb.net application
Can anyone help please ?
Many Thanks
Regards Andy

Hi all
Thanks for your answers.
At the moment I have found if I turn off all breakpoints the code runs fine.
I will try your answers but I have lost a lot of time on this and I have a deadline looming
Thanks again

Attempted to read or write protected memory. This is often an indication...

I receive the following error when debugging, but not when running the release version of my .NET 2.0 program:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt"
It's quite bizarre! I dont really know what else would be needed, but I can provide DLL versions etc if someone asks. Ive posted this in Ora/MTS forum because it only seems to happen when using a transaction on the client side

Hi I have similar issue. Like others, it seems that the error returned by oracle make ASP.NET (w3wp.exe) to have runtime error.
In my case, it occurs about once every day, consistently. The ASP still work even after runtime error but start to take up high cpu usage after 2nd and 3rd time of error, and totally crash (no reponse to the client request) after 3 or 4 times of errors. It recovers back after the server is restarted.

Crystal Reports Runtime SP3 (12.3.0.601)
We have a dll that prints a batch of reports. There are only three different reports but each is repeatedly printed with different parameters. The first time each report is called it is loaded (myReport.Load) and each table location is set. (myTable.Location = "mydb.dbo.mytable")
A few hundred of these can be printed every day. Approximately once a day we can get the following error:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
This only happens on the deployment machine. It might be hard to run the Process Manager on the deployment machine as this error varies the time it occurs and seems quite intermittent.
Once all the reports have printed we call a '.close' and '.dispose' on each report.
This error was also happening when we had the runtime 12.0.(SP1).
The error seems to happen mostly at:
myReportDocument.PrintToPrinter(1, False, 0, 0)

See if there are any updates for the printer driver.
Try a different printer driver.
See if there are updates for the DB client (e.g.; it may actaully be the DB client eating up the memory).
Check the Event Log for any warnings \ errors.

I did all the above steps but the message still coming out. Anyone can help??
Regards,
Anna

I have experienced this same error, and also found that reinstalling the DIAPI or deleting the temporary folder did not work.
However, I was eventually able to fix the problem by removing removing the reference to the DIAPI from my .NET project, removing the associated Interop file, and adding the reference again, thereby forcing .NET to re-create the COM wrapper. This fixed the problem, and I suspect that my code was calling a method that, although it existed in the Interop file, did not map correctly to the actual DIAPI COM object that was installed on the machine.
Hope this helps someone - I know I was happy to find a solution to this very frustrating problem!
