tDosPrn

Hi,

I am working on adding a bluetooth printer to my pocket pc app but when I try to compile I get the following:

* Linking errors *

It is this line that causes the problem:

Code: Select all  Expand view

oPrn:=TDosPrn():New(cPrnCom)

This command works fine in FWH.

Any idea what I am missing?

Tdosprn does not work with fw ppc

anyway bluetooth printing is similar to com printing , tdosprn will not be useful in this case

this is a sample code i use, you can find samples by searching this forum

you can also write to an ascii txt file and then use

Sendblue( MemoRead(cfile)) // function below

Hth

Richard

Code: Select all  Expand view

STATIC FUNCTION SENDBLUE(ctext)
LOCAL i, hOut

DPTCOM := "COM5:"   // you need to check the port on your ppc

hOut := CreateFile( DPTCOM,GENERIC_REWRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL )
IF hOut==-1
   MsgStop("xxxxxx error Port not found")
 ELSE
   FOR i = 1 TO Len( cText )
      WriteByte( hOut, Asc(SubStr( cText, i, 1 ) ) )
   NEXT
   CloseHandle( hOut )
ENDIF
return nil

Hi Richard,

Thanks, I will give your solution a try. It might actually work better for me since I can build the text file as I go ... no need to go back and forth through my data at the end of collection

Just an FYI ...

I was able to get the tDosPrn working perfectly with the Bluetooth and FWH.
I thought tDosPrn was available on the Pocket PC because there is an entry on the Wiki for it
