I've a program that uses the Interop.MSFlexGridLib.dll assembly and I cannot use gacutil to install in the GAC as it doesn't have a strongly typed name.  If you install the program from my distribution MSI it all works (and run that instance of the exe) it all works fine.  However I changed laptops and have had to re-add my projects references and hence I have found this problem (running VS 2013 on windows 8).

Does anyone now how I can register the dll in GAC ??

Urgent that I resolve this so any and all ideas appreciated.

Thanks, Tim

Thank you for you time folks!

We are using System.Reflection.Emit to generate code at runtime from source code (yes - as in a compiler). We provide correct symbol information to the ILGenerator with MarkSequencePoint etc, and enable all debug flags on the AssemblyBuilder. The assembly is kept in memory in the same process that compiled it and is executed directly.

When using the Visual Studio debugger to step through the source for the dynamically generated code it actually works perfectly, and Visual Studio seems to be fully aware of where code comes from in terms of files and line numbers.

HOWEVER - When exceptions are thrown by the generated code, the System.Exception objects contain stack traces that are completely wrong. They point to other (valid, but wrong) files and line numbers. It gets the class and method name right, but the file and line number pointed to has nothing to do with the code path the exception actually came from.

The files pointed to are so unrelated it seems it can't be linked to inlining or optimizations. The only pattern I can spot is that it seems to be offset by some files (in an imaginary alphabetically sorted list of source files the assembly was built from). However, this pattern is not 100% consistent, and it seems irrational that this is linked to the source of the problem.

If i construct a System.Diagnostics.Debug object from the Exception, it contains the same faulty information.

I am assuming that the .NET runtime uses the same metadata to construct Exception stack traces as the debugger uses for stepping through the code, in which case this behavior is really weird.

When trying to reproduce the problem with a much simpler project, the error does *not* occur, so unfortunately i have not been able to produce a minimal test case. The real case is quite complex.

I'm trying to find out if this is a known bug in .NET when dealing with dynamic in-memory assemblies, or if anyone has seen similar problems in other areas.

hi,

After updating OS in my laptop from windows 8 to 8.1, I am unable to connect to internet inside VMware Player. I have tried to troubleshoot the issue but ended up with nothing. Is this a known issue ?

Hi, guy

Could anyone give me some example how to use those 2 OpCode, I'm search and try in many way but non success (MSDN library not helpful in this case at all).

Hi,

We've been struggling with this strange issue for a while and we'd appreciate it if anyone can assist...

After upgrading our product to work with .net4 (we successfully used .net 3.5 until now) we suddenly started getting stackoverflow exceptions (it doesn't always happen and not on all machines but we have a machine that it happens constantly).

We used ADPlus to get a dump and found the thread that throws the exception.

Printing the clrstack showed the following for that thread:

and so on, the pattern continues...

It looks like the stackoverflow comes from clrjit code.

Has anyone had this issue before?

Any advice \ idea would be appreciated.

Thanks.

We developed a component which can be used by our customer to develop the DTM (A DTM is also a component, you can think of it as logical representation of automation smart device). Our customer created two DTMs, one is Communication DTM (provides communication ability) created based on latest version of our component (dtmMANAGER3 version 1.4.0.0), and the other one is normal device DTM created based on old version of our component (version 1.3.0.0). And there is a application called Frame Application, this application can load all the DTMs and create a topoloy with these DTMs (The topology is same as the topology of the corresponding physical devices in the field, for example a communication device is parent of a gateway device, and the gateway device is parent of normal smart device).

Our customer create a simple topology with these two DTMs, so the assemblies of these DTMs and their dependencies be loaded into same AppDomain. This causes two different versions of our component (dtmMANAGER3 Version 1.3.0.0 and 1.4.0.0) be loaded into same AppDomain. These two DTMs doesn't directly communication with each other(all the communication will go through FrameApplication), so we think it's ok for two different version of our component be loaded into same AppDomain (Our component has been strong-name signed).

These two DTMs work fine, except the WPF UI. In the xaml file it uses custom control from our component.

Here is the sequence:

1. Add the Communication DTM to the topology which will cause the dtmMANAGER3 component 1.4.0.0 be loaded into the AppDomain.

2. The WPF UI of the Communicaiton DTM can be opened.

3. Add the Device DTM to the topology as the child of the CommunictionDTM, this will caue the dtmMANAGER3 component 1.3.0.0 be loaded into the AppDomain.

4. If we open the WPF UI of the Communication DTM, it won't shown the UI. The WPFUI of communication DTM throws an XamlParseException.

I read this article http://msdn.microsoft.com/en-us/library/ms747086(v=vs.110).aspx.

In the "WPF and Assembly Loading" paragraph, it says: "Iterate through the AppDomain, looking for an already-loaded assembly that matches all aspects of the name, starting from the most recently loaded assembly."

In our scenario the recently loaded assembly is dtmMANAGER3 1.3.0.0 (the dtmMANAGER3 1.4.0.0 is loaded earlier). But the WPF UI of the Communcation DTM should works with the dtmMANAGER3 1.4.0.0. Is this the cause of our problem? If so is there any solution for this?

Hi,

Hello,

I'm operating in a scenario where legacy VB6 code must interoperate with C# code. So far no problems except one special case where a C# library must substitude a former ActiveX-DLL.

The problem that arises is the indexer of a C# class that is being consumed from VB6. I can get values using the indexer without issues but when trying to set values from VB6 I'm running into error 424 "Object required".

Here's the C# code:

[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]  
[ComVisible(true)]    
public interface ITestList 
{         [DispId(0)]      Object this[short Index] 
     {             [DispId(0)]set;           [DispId(0)]get;          
     }        
}

[ComVisible(true)]
[ClassInterface(ClassInterfaceType.None)]
public class TestList : ITestList
{
    private List<Object> internalList = new List<Object>();

    public TestList()
    {
    }        

    public Object this[Object Index]
    {
        [return: MarshalAs(UnmanagedType.Struct)]
        get
        {
            // code for setter goes here
            return "test";                   
        }
        [param: MarshalAs(UnmanagedType.Struct)]
        set
        {
            // code for setter goes here but even without code the error occurs
        }
    }

}

Access from VB6 code:

'This is working
MsgBox obj.Item(1)
'This throws 424 "object required"
obj.Item(1) = "test me"

I've already investigated a lot but none of the findings solved the final problem. Please note that I'm not allowed to change the way VB6 is accessing the property. Thus the workaround to implement custom methods cannot be used.

I'm sure there's a way to implement the indexer in a way it's setter can be accessed from VB6 or at least I'd want to understand why this won't work.

I recently migrated a web application from .net 3.5 to .net 4.5. The machineKey element is:

<machineKey validationKey="KeyA" decryptionKey="KeyB" validation="SHA1" decryption="3DES" compatibilityMode="Framework20SP1" />

I am getting hundreds of these errors:

Exception type: System.Web.HttpException
Exception message: Unable to validate data.

ViewSource suggests the culprit could be an asp:Menu and/or viewstate.

Searching for a solution suggests machineKey could be the problem.

Thanks for any help.

I am calling a third-party unmanaged DLL from vb.net (framework 4.5) and on rare occasions the third party DLL thows an AccessViolationExcpetion ("Attempted to read or write protected memory. This is often an indication that other memory is corrupt."). 

I have added the <HandleProcessCorruptedStateExceptions> attribute to the method which calls the DLL as follows: -

When running in debug mode in VS2013 the exception is handled and the application quits as expected. However when I build and run the app outside of VS2013 it just hangs at this point and no exception is handled. The program doesn't even crash.

Is there anything I have missed here which makes debug vs build different?

Thanks for reading this...

It seem that the MSVCR80.dll is missing from my computer. This only happened today, when I tried to access Apple I-Tunes.

How to I:-

a) Get the file

b) install it in the appropriate space.

Please Help!

Hi Everyone !

We are developing a 100% managed .NET Application/C# that consists of several Windows-Services and Client-Applications. Until April 2010 the Target was .Net 3.5 SP1. Meanwhile we converted all Projects to target .NET 4.0. And now we are expierencing APP-Crashes which happens every now and then (1 or twice a Week) if we are running our Tests on Win7 or 2008 R2.

The Faults are of Sort: 

In some cases I get a Mini-Dump which I was able to debug to a certain point, the Methods where the crash happens are different e.g.

Process Architecture: x64
Exception Code: 0xC0000005
Exception Information: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
Heap Information: Not Present

We now rolled back all our projects to .NET 3.5 Target, and the above AppCrash did not occur anymore (In a 1-Week continous Test). So we went searching for this error but suprisingly there are only few others that reported this error. Since this is an internal CLR-Error of .NET 4.0 we cannot believe that we are the only ones having this problem. But maybe the are more around also still trying to find a reason for it ? Would be glad to ge some Idea about this.

Hi,

Hello,

How would I access free ROTOR to implement an universal bytecode of C++11.NET.

Thanks

I am Prasanna and new to Cmdlet development.

I have to write a cmdlet that takes 4 parameters - A, B, C and D. B is valid only when A is true. And D is valid only if C is true.

I tried to use Dynamic Parameters.

To return 2 different fields depending on A or C, should I write 2 Parameter-classes and return those classes in the call to getDynamicParameters () ?.

Assuming that user specifies both A and C, the method must be made to return both the classes, right ? Is this supported ? How would I make getDynamicParameters() return both ? I derive my CmdLet class from Cmdlet.

Looking for some help on this to support my project-related work at office.

Hello,
I don't know where to post the topic, because it relates mixed applications using unamanged and managed dlls.

A lot of things have been written about loading phase. I cannot find anything about unloading phase.

We had some massive problems during termination phase of our executables.

The problem was that an unmanaged dll (3rd. party!) is using pointers to managed objects

This leads to a crash of the executable, because the unmanaged dll want's to access managed objects during unload of dll.

This has to crash, because of that phase, the CLR has already done its house keeping.

That means the the DLLDetach Code form the 3rd party library is accessing code which can not run anymore.

My understandings is the following for the initialization/deinitilization phase of mixed applications

1. crt is initiliazed

2. crt based variables are initialized (e.g. statics)

3. CLR is intialized

4. CLR base variables are initialized.

For unload it seems to be vice versa

1. CLR is doing house keeping for memory and code

2. CLR is deinitialized/unloaded

3. CRT is doing house keeping for memory and code

4. CRT is unloaded

For a unmanaged DLL (like our 3rd party library :( ), that means that it trys to call e.g. destructors being managed or using managed code. But this exatly happens after the CLR has already done its house keeping . So it crahes.

Workaround:

We found a way to tell that dll to release its internal uses objects, before the exe terminates.
That works, because all runtimes are stille availab.e

But why is Microsoft not fixing the issue.

Here is a proposal hot wo fix it.

Decouple memory house keeping from unlouding the runtimes.

Introduce an additional deinistilization phase which is cleaning the memory, but is not unloading the runtime.

After that phase, after all unmanaged heaps and all managed objects are released,

unload the runtimes.

This ensures that such cross dependent components are able to call there destucturs.

Same is true for initialization

first load both runtimes, than call dll attach and correspondin methods.

Regards
