Import bitmap to blob from byte-array in C#.NET

John_Reinhold · 2006-10-04

How do I import a bitmap into a blob-field from an automation that returns the bitmap as a byte-array? I need to do it from NAV4, not from C# by C/Front.

The blobfield.import only accepts filenames...

Of course I can save it in disk and then read it, but thats slow.

BTW: I use Visual Studio 2005

I'm afraid that's the only way.

You can create instream for the BLOB, but I am afraid that the stream is not compatible with C#... but you can try something around that...

Hi Kine,

I also want to return bitmap in BYTE array to Navision but from COM.
Can you please give me an example of how Navision side I can handle BYTE array using InStream/OutStream.

Thanks for any help.

Sorry, I have no tips for you. I just know, that there are some posts about connecting Nav Streams with COM Streams.

You can export the bitmap with an xmlport en use a base64 to encode the bitmap into a bigtext node, then stream the xml file in .net object and decode it there.
But that's much slower then writing the bitmap to a temp file.

Howdy, Stranger!
