Hei p-HD
Tok en rask kikk på Text-tv programmet som følger med Hauppauge PVR-250, VTPlus. Den kan ikke dette 'out of the box', men det er kanskje mulig via script språket og/eller via oppdatering av et DDE område.
Sakset fra VTPlus help:
2. Data port:
Data is fetched with DDE directly from the displayed windows. A list of these windows you get with a DDERequest for the item Topics under the topic System.
Connect your program with VTPlus | window (for example VTPlus | ARD422). First you can check whether the selected page including all subpages have been received in your destination window. Ask with DDERequest about the item Status. The feedback you can get are "Ready" for complete reception or "Busy" for not received completely.
There are two basic possibilities to read in the data.
Manual You fetch the data by a single request yourself. The used terminology depends on the used program, for example DDE-Request, Linkmode 2 or Cold Link. You will get an error feedback, when one or several selected subpages are not yet available. We advise you therefore, after you have requested data via the command port, to establish an automatic connection with VTPlus and to ask for Status.
Automatic When the data changes, VTPlus will deliver the data automatically. This is always experienced when all affected subpages are being received and at every update, when the option update continuously is marked. You have to build a continuous connection, the often used terminology depends again on the used program and may vary from, for example DDE-Advise, Linkmode 1 or 3, Warm Link, Hot Link.
The requested item has to be transferred with the following Syntax:
f,l,fi,fp
f first subpage from 1 ... 64 (Preset 1). If you use -1 here, the actual displayed subpage is transferred. In this case the parameter l is ignored.
l last subpage from 1 ... 64 (Last available preset)
fi A filename of an optional referred filter with complete path information, which has been created with the VTPlus Filter editor , or command file for an external Filter function.
fp Parameter for an external filter function, optional in "".
The element fp may be optionally enclosed with (fp) or 'fp'.
Examples:
=VTPlus|ard422!'1,2,c:\tt\ard422.vtf'
stands for an Excel connection to VTPlus, where a filter is being used. When you mark your complete working space on your Excel worksheet and change with the command ctrl + shift + Enter a so called "Array" is created. You will find more extensive information in your Excel-manual.
{DDEAUTO VTPlus ard422 1,2}
creates a Winword connection to VTPlus. No filter is being used in this example.
I script mode er følgende tilgjengelig:
Exports the page in the given window.
Syntax:
EXPORT ks FILE=d APPEND=a CHARSET=c FIRST=f LAST=l FILTER=fi FPARAM=fp QUALITY=q
k ID, e. g. CNN, optional
s Page 100 ... 899
d Filename for export with full path
a append to existing file YES or NO (Default NO = overwrite)
c Character set ANSI or ASCII (Default ANSI)
f first subpage from 1 ... 64 (Default 1)
l last subpage from 1 ... 64 (Default last found)
fi Filename of an optional filter command with full path, created with VTPlus Filter Editor or command file of external filter function. If the path is not or relatively given the VTPlus directory is assumed as reference.
fp Parameter for an external filter function, optional in "".
q Exportformat TEXT, BLACKWHITE or COLOR (Default TEXT)
Beispiel:
EXPORT CNN422 FILE=c:\stock\newyork.txt LAST=1
exports the first subpage of the page in window ARD422 in the file newyork.txt using ANSI character set.
Comment:
Subdirectories are created automatically. If you use the export formats BLACKWHITE or COLOR the FIRST and LAST parameter must have the same value because only one image can be exported. In that case the bitmap file extension (*.bmp) should be used.
Sier ikke at det er lett, men kanskje mulig med hjelp av VTPlus + en DDE applikasjon som lagrer hver update til fil + en bøtte tid og tålmodighet.
