DotNet MemoryStream

mik

Hi,

I am just working on an external component and need to pass MemoryStreams to this .dll.

I found the following information for this topic.

http://kauffmann.nl/index.php/2012/04/04/binary-data-with-nav-web-service/

In this example you can see that he is using the command

COPYSTREAM(MemoryStream,InStream);

I have atm the problem, that I can use this because of following error.

](*,)

Unable to convert from Microsoft.Dynamics.Nav.Runtime.NavDotNet to Microsoft.Dynamics.Nav.Runtime.NavOutStream.

Every DotNet Global is running on Client ("yes")

I'm using a Three-Tier Environment. Version: 7.10.36.366

Hi,
I think I just found the solution after the longest 4 hours of my life. \:D/

I did the following....

Name		        DataType	        Subtype	Length
AdvancedPDF	DotNet		mpAdvancedPDF.AdvPDF.'mpAdvancedPDF, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e520dfe28c1ca5b5'	
MemoryStream	DotNet		System.IO.MemoryStream.'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'	
Stream		DotNet		System.IO.Stream.'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'	
InStr		        InStream	


MemoryStream := MemoryStream.MemoryStream;
Document.CALCFIELDS(BlobField);
IF Document.BlobField.HASVALUE THEN BEGIN
  Document.BlobField.CREATEINSTREAM(InStr);
  Stream := InStr;
  Stream.CopyTo(MemoryStream);
  Message(Format(MemoryStream.Length()));
END;

Was trying also, but method CopyTo does not exist on a system.io.stream???

How did you managed compiling that code?

In this stackoverflow post it is said that the CopyTo() method has been implemented since .NET 4 but Mik gives a list of .net vars using version 2, maybe his code uses version 4 and he wrote version 2 on mibuso ?
