Is it possible to convert big text to inStream? I dont want to write into a file and then read from it.

Please help.

Yes

table.BlobField.CREATEOUTSTREAM(ostream);
bstr.WRITE(ostream);

table.BlobField.CREATEINSTREAM(istream);
bstr.READ(istream);

Thanks.

But I have got a text variable.

lets say "txtA" being passed from some other source to a function
Now I want to load it into a stream to pass it xml port.

so what needs to be done.

txtA.CREATEINSTREAM(ostream);
bstr.READ(istream);

right?

There's a table that you can use for this purpose, called TempBLOB. Add a temporary record variable based on that table, and use its methods:

TempBlob.Blob.CREATEOUTSTREAM(outstr);
TempBlob.Blob.CREATEINSTREAM(instr);

Now you can use other automation to actually populate the out and instreams. Read the outstream from a big text, and use the outstream as the source for your XMLPort.

You would use CREATEOUTSTREAM only for outstreams, not instreams. For that you would use CREATEINSTREAM. By using the TempBlob table, when you read the instream into the Blob field, you can set its value from an instream, and use it to create an outstream, based on the same field.

hI thanks for your help.
I am just new to nav cal coding...

ProcessCustomers(InputXML : BigText) status : Boolean

tempRec.Blob.CREATEINSTREAM(XMLInStream);
InputXML.READ(XMLInStream);
XMLPORT.IMPORT(123456751,XMLInStream);
status := TRUE;

not getting the data into the table through XMLPORT.

Am i still doing any thing wrong?

please advise.

Yes, you are reading the blob into the BigText instead writing it into outstream and reading it through instream...
