Re: [Gambas-user] Serial I/O with byte data
Following should work for you: Public Sub XXX_Read() Dim iLen As Integer Dim aData As Byte[] iLen = Lof(Last) aData = New Byte[] aData.Resize(iLen) Try aData.Read(Last, 0, iLen) End You need to get the length (lof) first, then resize array ... only then you can read it. 2017-05-14 21:56 GMT+02:00 Tobias Boege : > On Sun, 14 May 2017, alexchernoff wrote: > > Good day all, > > > > Anyone know how to read data received on serial port into an array of > bytes > > instead of string? > > > > I think that's not possible. > > > String gets unreadable binary characters, so how can I > > put them into byte[] or so? > > > > This shouldn't be a problem.

Gambas Strings are not null-terminated and can contain any sequence of bytes, which includes non-printable characters (which I think is what you meant by "unreadable" characters). If you insist on a Byte[], read it into a String and use Byte[].FromString(), but there is no way to go around the String, AFAICT (and that is because there is no need to, as Strings can handle binary data just fine).

Re: [Gambas-user] Serial I/O with byte data
Good day all, Anyone know how to read data received on serial port into an array of bytes instead of string? String gets unreadable binary characters, so how can I put them into byte[] or so?

Re: [Gambas-user] How to use gb.map ".AddPolyLine( )" method ?
Hi Fabien, the gb.map works very well. Thank you for this. But I have questions about AddPolyLine: 1) The AddPolyLine() always draws the outline of polygon. Is it possible to have only lines with an 'open end'? I tried to set the last Mappoint to the same values as the next-to-last Mappoint. That does'nt help. 2) Can I manipulate the thickness of the line? Thank you in advance.
