Windows error 0x00000056, 86

Detailed Error Information


MessageThe specified network password is not correct.
Declared inwinerror.h

This appears to be a raw Win32 error. More information may be available in error 0x80070056.


This is a Blue Screen of Death stop code. More information is available in the Knowledge Base article Bug Check 0x56: INSTRUCTION_COHERENCY_EXCEPTION.

HRESULT analysis[3]

This is probably not the correct interpretation of this error. The Win32 error above is more likely to indicate the actual problem.

This code indicates success, rather than an error. This may not be the correct interpretation of this code, or possibly the program is handling errors incorrectly.

Possible solutions


Investigating Memory Leak


The stack recorded when using GFlags is done without utilizing .pdb and often not correct. Since you have traced the leak down to a specific size on a given heap, you can try to set a live break in RtlAllocateHeap and inspect the stack in windbg with proper symbols. I have used the following with some success. You must edit it to suit your heap and size.

 $$ Display stack if heap handle eq 0x00310000 and size is  0x1303
 $$ ====================================================================
bp ntdll!RtlAllocateHeap "j ((poi(@esp+4) = 0x00310000) & (poi(@esp+c) = 0x1303) )'k';'gc'" 

Maybe you then get another stack and other ideas for the offender.

Investigating Memory Leak


The first thing is that the new operator is the new [] operator so is there a corresponding delete[] call and not a plain old delete call?

If you suspect this code I would put a test harness around it, for instance put it in a loop and execute it 100 or 1000 times, does it still leak and proportionally.

You can also measure the memory increase using process explorer or programmatically using GetProcessInformation.

The other obvious thing is to see what happens when you comment out this function call, does the memory leak go away? You may need to do a binary chop if possible of the code to reduce the likely suspect code by half (roughly) each time by commenting out code, however, changing the behaviour of the code may cause more problems or dependant code path issues which can cause memory leaks or strange behaviour.

EDIT Ignore the following seeing as you are working in a managed environment.

You may also consider using the STL or better yet boost reference counted pointers like shared_ptr or scoped_array for array structures to manage the lifetime of the objects.

VisualStateManager thrown exception


Background property is not a color. It's a brush, so you can't animate it with ColorAnimation. Brushes can be animated with ObjectAnimationUsingKeyFrames. But first you have to create a new brush with the target color (in your case it's red).

You can add SolidColorBrush to resources in the same place where is your style:

<SolidColorBrush x:Name="RedBrush" Color="Red" />

<!-- And here goes your button style... -->

Then you can use it in object animation.

<VisualState x:Name="Pressed">
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="RootElement"
            <DiscreteObjectKeyFrame KeyTime="0" 
                                    Value="{StaticResource RedBrush}"/>

PostSharp causes BadImageException when applied to generic methods -- errors when running peverify.exe


"System.BadImageFormatException" usually indicates a 64-bit/32-bit problem.

If you compile your code for "Any CPU" and run it on a 64-bit processor it will be JIT compiled to 64 bit. If it then calls any code (e.g. in an unmanaged dll) that is 32-bit, you'll get this exception when it tries to jump from 64-bit to 32-bit code.

If you're running on a 64-bit OS it's therefore possible that something in your upgrade has caused your program to get a mixture of 32-bit and 64-bit code in it. If you're running on a 32-bit OS then then can't be the problem, though, in which case it may indicate a corrupted binary.

If it is 32/64, then you can do the following: - Make sure all the dlls you use are the same bit-ness as your app, or - If you can't replace some 32-bit dlls with 64-bit versions, try compilng your app as "x86" rather than "Any CPU". This will force it to be compiled to 32-bit code even on a 64-bit PC, which will mean it has to run under WoW64 as a 32-bit app but it will be compatible with its 32-bit dlls.
