WriteToFile?

[soks2626]

Hi again-
I was wondering how I would be able to take a Binary piece of data (like an image stored in a table) and write that to a specific directory and file name based on other contents on the same row as that image data. I'm thinking "WriteToFile", but that doesn't seem to let me write to a specific place or let me specify how I want the file to be named.

Any suggestions? Thanks!

Alex,

Something like this should work:

method pushButton(var eventInfo Event)
var
   binDocData   Binary            
   tcDocTable   TCursor           
endVar

const
   BLOB_TABLE = ":work:blobdemo"
endConst


   if not tcDocTable.open( BLOB_TABLE ) then
      errorShow( "Can't Open " + BLOB_TABLE,
                 "Use [>>] for more details." )
   else

      ; Now, write the binary data to the file
      binDocData = tcDocTable."BlobData"
      binDocData.writeToFile( "c:\\myblob.bin" )

   endIf

   ; Note: Always explicitly close TCursors
   if tcDocTable.isAssigned() then
      tcDocTable.close()
   endIf

endMethod

Hope this helps...
