Saving drawing with 'SaveToStream' creates broken file

StefanChrist · Post by **StefanChrist** » 22 Oct 2018, 10:39

Hello Support,

I am using the SaveToStream function to write a drawing into a stream, which is stored in a database. It is also possible to create a DWG file with this data. Sometimes the exported file seems to be corrupt, at least TrueView shows a message when opening those files:

"Errors were detected in the drawing. The file cannot be opened without being recovered."

Is there a way to check what is causing those issues?

I am sorry that I cannot attach the generated file to this thread but I could mail it to you if this would help you.

Thank you,
Stefan

Hello Mikhail,

this is the codes that stores the DWG file:

Code: Select all

Dim s = New System.IO.MemoryStream
CADtoDWG.SaveToStream(Drawing, s)
      Dim fs As New FileStream("C:\TMP\" & Date.Now.ToString("yyyy-MM-dd") & ".dwg", FileMode.Create)
      s.WriteTo(fs)
      fs.Close()
      s.Close()

Thank you.

Hello Stefan,

The code is correct. Could you please mail us the drawing which you save through a MemoryStream and get a corrupted DWG file?
