how to displaying contents of a field in oBrowser

[Phil (OmnisList)]

Hi Doug, Mike,

The doc say:
$/setdataurl/() 	

$/setdataurl/(vData,cMediaType[,cWidth,cHeight]) assigns a data URL for 
the supplied data, with the specified media type, to $urlorcontrolname.

vData can be either:

binary - the data represented by the URL

or another type - OBrowser converts the data to character if necessary, 
and then UTF-8, to become the data represented by the URL.

cMediaType is a MIME type specifying the type of the data e.g. 
text/plain or image/png.

cWidth and cHeight are optional. They are only relevant if vData is 
binary, and the data is an image. In this case, the data URL represents 
an img of the specified cMediaType, sized using the CSS sizes width and 
height e.g.

$/setdataurl/(image, “image/png”, “100%”, “100%”)


Suggesting a limitation to what it can represent?

So, I suspect, as has been suggested, saving it to a temp file(s) first 
might work better...
if not very cumbersome...


Just seen your latest reply Doug, how did you send the HTML directly to 
oBrowser...
