Attempted to read or write protected memory calling GetCompanyService() C#

I am getting the error;
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
when running the code;
if (sboCompany.GetCompanyService().GetAdminInfo().RoundingMethod == SAPbobsCOM.BoYesNoEnum.tYES)
// My code here
This is happening on a Terminal server session on Server 2003 R2 Std x64 Edition Service Pack 2 running SAP Business One 2007 A (8.00.232) SP: 01 PL: 07
but works OK on a standard Windows XP Professional 2002 SP3 Machine running SAP Business One 2007 A (8.00.181) SP:00 PL:46
I have managed to resolve this by accessing the Roundmthd field in the OADM table directly using a recordset object, but would like to abe able to use the proper api if possible!
Can anyone help?

Within IF clause, it is better comparing two values indirectly that you have already assigned them to your own variables. try it to see.
Thanks,
Gordon

PInvoke - Issue while calling DJVU function from C# Code - Attempted to read or write protected memory

Hi,
I know there are many questions in this subject but none of them help to resolve the issue I am currently facing.
Below is the signature of C Function from DJVULibre added in .NET code
[DllImport("C:\\Program Files\\DJVULIBRE\\LIBDJVULIBRE.dll", CharSet=CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
private unsafe static extern int ddjvu_page_render(IntPtr page, ddjvu_render_mode_t mode, IntPtr pagerect,

try
IntPtr ptr1 = (IntPtr)Memory.Alloc(Marshal.SizeOf(prect));
Marshal.StructureToPtr(prect, ptr1, false);
IntPtr ptr2 = (IntPtr)Memory.Alloc(Marshal.SizeOf(rrect));
Marshal.StructureToPtr(rrect, ptr2, false);

}call to ddjvu_page_render in above code is throwing "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
Prior to this post I must have tried all the option could find in various blogs.
Appreciate any help, is almost a day I am clueless, your timely help could save my job

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:

Recompile the app after SP3 is applied.

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.

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.

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.

Hi,
I am using 2007B PL08. The following are my coding:
Dim oCompanyService As SAPbobsCOM.CompanyService
Dim oCompanyAdminInfo As SAPbobsCOM.AdminInfo
Pub.User.Company.NameEng=oCompany.CompanyName
I can run the above coding properly yesterday but there is no reason that i got the following message suddenly today
Interop.SAPbobsCOM:Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
1. I try to re-boot the machine
2. I try to connect the program to another testing database
3. I try to re-install the DIAPI
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!

Attempted to read or write protected memory problems

Hi there, we are having some issues with ODP.net. every few days after our system has been used quite a lot we get the "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." errors.
I can reproduce this just by launching some threads that all make some DB calls, and after a while (took over an hour in the case) we encounter the error. It it not just one DB call causing it, looking at the logs it does appear to only be calls to 'Get' data, but just about all of them have failed at some point.
Yes we have upgraded to the latest version 11.1.0.6.20 and it still happens. Here are some stack traces, Oracle.DataAccess.Client.OpsSql.AllocSqlValCtx seems to be the most common in the stack traces though, others do occur.
at Oracle.DataAccess.Client.OpsSql.AllocSqlValCtx(OpoSqlValCtx*& pOpoSqlValCtx) at Oracle.DataAccess.Client.OracleCommand.BuildCommandText() at Oracle.DataAccess.Client.OracleCommand.ExecuteReader(Boolean requery, Boolean fillRequest, CommandBehavior behavior) at Oracle.DataAccess.Client.OracleCommand.ExecuteReader() at BUPA.HUGO.Common.DataAccessLayer.Database.StoredProcedures.ProspectSP.GetPersonProspectStoredProcedure.GetFullPersonDetailsDataReader(Int64 personId) in c:\Projects\CC.NETbuild_Hugo_Prod\Server\RF_Hugo_Services\Common\DataAccessLayer\Database\StoredProcedures\ProspectSP\GetPersonProspectStoredProcedure.cs:line 43
Sometime the top of the stack is

or
at Oracle.DataAccess.Client.OpsDac.Read(IntPtr opsConCtx, IntPtr opsErrCtx, IntPtr opsSqlCtx, IntPtr& opsDacCtx, OpoSqlValCtx* pOpoSqlValCtx, OpoMetValCtx* pOpoMetValCtx, OpoDacValCtx* pOpoDacValCtx) at Oracle.DataAccess.Client.OracleDataReader.Read()
Does anyone have any ideas? I saw some older post just asking people to try the new version (which we have). Any help on this matter would be great. We are having trouble figuring out if it is something we are not doing correctly or if there is a bug in ODP.NET.
Thank you,
Luke

Hello,
I've got exactly the same problem. We're using ODP.NET 10g R2 10.2.0.3.02 with RAC database. I found that this error only occurs after a Failover event.
My application is .NET 3.0 WPF app.
I'm able to reproduce this error at any time.
Please have a look at some source code:
//opening OracleConnection:
theConn.Open();
theConn.Failover += new OracleFailoverEventHandler(theConn_Failover);
// handling the Failover event as stated in the docs:
static FailoverReturnCode theConn_Failover(object sender, OracleFailoverEventArgs eventArgs)
Logging.LogInfo("DB-FailoverEvent: " + eventArgs.FailoverEvent.ToString() + " - Type: " + eventArgs.FailoverType.ToString());
switch (eventArgs.FailoverEvent)
case FailoverEvent.Begin:
Logging.LogInfo("FailoverEvent.Begin - Failover is starting");
Logging.LogInfo("FailoverType = " + eventArgs.FailoverType.ToString());
break; // TODO: might not be correct. Was : Exit Select
case FailoverEvent.End:
Logging.LogInfo("FailoverEvent.End - Failover was successful");
break; // TODO: might not be correct. Was : Exit Select
case FailoverEvent.Reauth:
Logging.LogInfo("FailoverEvent.Reauth - User reauthenticated");
break; // TODO: might not be correct. Was : Exit Select
case FailoverEvent.Error:
Logging.LogInfo("FailoverEvent.Error - Failover was unsuccessful");
// Sleep for 3 sec and Retry
Thread.Sleep(3000);
return FailoverReturnCode.Retry;
case FailoverEvent.Abort:
Logging.LogInfo("FailoverEvent.Abort - Failover was unsuccessful");
break; // TODO: might not be correct. Was : Exit Select
default:
Logging.LogInfo("Invalid FailoverEvent : " + eventArgs.FailoverEvent.ToString());
break; // TODO: might not be correct. Was : Exit Select
// comment following lines will not raise an error
if (connect2DB())
return FailoverReturnCode.Success;
else
return FailoverReturnCode.Retry;
And here's the source for checking DB-connection:
private static bool connect2DB()
if (null == myConn)
myConn = openOracleConnection();
if (null == myConn)
Thread.Sleep(5000);
return false;
try
if ((myConn.State == ConnectionState.Broken) || (myConn.State == ConnectionState.Closed))
myConn = openOracleConnection();
String sql = "SELECT 1 FROM dual";
using (OracleCommand cmd = new OracleCommand())
cmd.Connection = myConn;
cmd.CommandText = sql;
cmd.CommandTimeout = 2;
using (OracleDataReader dr = cmd.ExecuteReader())
dr.Read();
catch (Exception ex)
Logging.LogError(ex);
closeOracleConnection(myConn);
myConn = openOracleConnection();
setDBConnState();
if (null != myConn)
if ((myConn.State == ConnectionState.Broken) || (myConn.State == ConnectionState.Closed))
return false;
else
return true;
else
return false;
When I don't call "connect2DB()" in the failover event handler then everything is fine - otherwise oops the error occurs after approx. 14 hours after application runtime.
Regards
Sven

Hi Venkat,
According to the error message, I guess that the error occurred when you previewed the report in Business Intelligence Development Studio (BIDS).
Based on my research, I think it may be a Window Layout issue of Visual Studio. Please try the steps below:
Click “Window” button from the toolbar ribbon.
Click “Reset Windows Layout” option.
Click “Yes” to finish the operation.
The following thread is for your reference:

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
Don

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.

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
Regards Andy
