EWS, EWS proxy and Graph

October 26, 2018, 11:57 am

Hi all,

I'm looking for more information on these API's. Just a few questions about them and how we are using EWS.

In our Web References folder of our web application it appears that we have a reference to the EWS proxy library. Is that library designed to work with exchange via a proxy server?

If so, I'm looking into possibly getting rid of that API and going with EWS or Graph. Currently our application reaches out to our onsite exchange server via URL. It sets up an exchange service binding then we check for emails, and process them into a database. This is some old code and it hangs every time the email contains an inline image(like a picture in the signature), then we manually remove it and resend it.

I'd like to bring this code up to date and process the emails differently. Is Graph an updated API that can handle this or do I need to stick with EWS?

"Safe" to use System.Diagnostics.Trace.CorrelationManager.ActivityId in production?

October 29, 2018, 2:17 am

We have a REST API that calls stored procedures to perform various tasks.

We need to track and log which stored procedures are called as a result of individual REST API HTTP requests (may be multiple). 

For simplicity we are considering setting System.Diagnostics.Trace.CorrelationManager.ActivityId = Guid.NewGuid() in the REST API Controller when every request is received (in a "filter") and then picking it up again just before calling the stored procedures and including it as a parameter. This way we don't need to include the guid as a parameter in every single method call in every layer of the server. 

Is it "safe" to use System.Diagnostics.Trace.CorrelationManager.ActivityId like this in production? E.g. it can't be "switched off" by accident somehow in the target environment? 

Any other performance, security or multi threading issues worth considering by doing it like this? 

Our REST API runs self hosted as a Windows Service. We are using .NET Framework 4.6.1.

SignalR Logging no time

I entered the script in the 

<system.diagnostics>

section of the service config file which is supposed to produce an init log and a transports log.  It is producing a transports log but there are no timestamps which would be helpful in troubleshooting the problem we're having with the client and service loosing connection with each over overnight. 

Anyone know how to record times similar to event logs in this transport file?

the original article with the script is here https://docs.microsoft.com/en-us/aspnet/signalr/overview/testing-and-debugging/enabling-signalr-tracing

TIA

How to evaluate column expressions without DataTables

October 17, 2018, 3:57 am

Hi,

I’m looking for a way to evaluate the column Expression available in ADO.NET … without using a DataTable instance.

Say I have a column expression like iif(a > b, true, false)

Is there a way to evaluate this expression by passing somehow values for a and b?

I looked at the  Compute method on DataTable but it is not quite what I’m looking for:

object result1 = new DataTable().Compute("20.0 / 2", null);

object result3 = new DataTable().Compute("iif(10 > 5, true, false)", null);

object result2 = new DataTable().Compute("iif(a > b, true, false)", null); -- how to evaluate this

Idea behind this is to move away from DataTable to simple array structure for performance reason.

Still I need to support a way to generate the legacy expression used.

I would rather avoid building the expression string to generate this as it will be poor performance for large number of rows.

Thanks in advance for your help

Problem importing a dll in NAV

Hi everyone,

I've got an issue with a dll from a printer development environment. The issue is that I need to send some files to prinet to a certain printer, and I found that there's a development dll available for that printer. That printer wasn't singed, it didn't have the public token.

I found a post, and signed this way:

1- Using the Visual Studio 2015 command prompt

2- sn -k tsclibnet.snk

3-ildasm tsclibnet.dll /out:tsclibnet.il

4-ilasm tsclibnet.il /res:tsclibnet.res /dll /key:tsclibnet.snk /out:tsclibnet.dll

5-Found that process ended correct with sn -vf tsclibnet.dll

But when importing the DLL into a dotnet object in navision, I still having this problem:

Am I doing something wrong with the signing? Should I sign it with another application?

ManualResetEvent.WaitOne throws System.AccessViolationException

We have a multi-threaded application that receives events from a device that unlocks a worker thread.

When we receive an event, EventWaitHandle.Set() is called to unlock the worker thread and then goes back to waiting for other hardware events.  

Before the WaitOne can return in the worker thread the following error is recorded in the dump file.

System.AccessViolationException   Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I can not figure out why this is happening.  Thread 26 comes from a 3rd party library, and is back waiting by the time the crash occurs.

This is a mixed native/.Net 4.6 C++ app.  I'd be thankful for any help.

Thread 49 is waiting, thread 26 is setting the event and then going back to sleep.

In exe.5788.dmp the Module C:\Windows\System32\KERNELBASE.dll has caused an access violation exception (0xC0000005) when trying to execute instructions from a non-executable address at memory location 0x00000000 on thread 49

app.manifest - turn on all operating systems?

Hi all;

We have created an app.manifest to turn on high-res processing. We run well on all versions of Windows. Should we uncomment the settings for each version? Or as we run on all, leave it commented so if there's a newer version of Windows we still run fine.

System.Web.HttpFileCollectionWrapper - An odd beast - Enumerator exhibits weird behavior, not conventional, opinions?

October 22, 2018, 2:31 pm
$
0

The "System.Web.HttpFileCollectionWrapper" .NET Framework type implements System.Collections.IEnumerable so I've tried enumerating over an instance of it using a foreach() construct as follows:

foreach(var X in this.Request.Files) {

    // do something with object in collection

}

This enumerator returns just a key (System.String) in the collection and if a user sends multiple files using a single HTML input element of type file, all the keys are the same.

However, the indexer returns the appropriate objects one would expect to be getting from the enumerator. Which is a System.Web.HttpPostedFileWrapper for each file sent up by the user.

Does anyone besides myself think this is just weird? Obviously, it can be done programatically but from an intuitive perspective about what a programmer expects to get back when enumerating through the type I can't help but be baffled by the behavior personally.

Thoughts please? Thanks in advance!

Microsoft.GroupPolicy ComputerConfiguration Class

Good day,

I am hoping to put together a POC in our AD test environment using the Microsoft.GroupPolicy namespace for checking individual machine's computer configurations.

There is a heap load of documentation on user configuration in general through C#, but this particular namespace doesn't seem to shed any light on its functionality at all:

https://msdn.microsoft.com/en-us/library/windows/desktop/microsoft.grouppolicy.computerconfiguration(v=vs.85).aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1

I'm not sure if I'm just searching for the wrong language, and apologize in advanced if this a duplicate question.

If anyone knows whether or not this would be a viable solution, and if so, could share some examples or more thorough documentation on the matter, I would be greatly appreciated!

Thanks so much for your time!

Cannot add C# .NET4.6.2 project as a reference of C++ project

Hi,

Our company used to use VS2010 to build a C++ project that referenced a C# project that target .NET 4.0 framework.  Everything seems to work fine.

Then we decided to move to VS2015 professional and latest .NET framework. Solution seems to be converted properly, however, when I tried to change the C# project to target .NET4.6.2, the C++ project that referenced it start to complain about cannot use any helper function from that C# reference.  Then I tried to remove and re-add the project, and I got the following error.

    One or more error occurred.

    A referenced to <project> cannot be added because it is incompatible with this project.

The C++ project default using:

Target Platform Version: 8.1

Platform Toolset: Visual Studio 2015 (v140)

I've changed Target Platform to 10.0.14393.0.  Problem still exist.

Then I tried to change the C# project to target .NET 4.6 or 4.5, I still can't add the project to the C++ project until I change it back to .NET 4 then it allows me to add.

Any help would be appreciated.

Thanks,

Gary
