Display jpg via http url

Display jpg via http url

Postby rhlawek » Tue Dec 11, 2012 9:46 pm

Is there an example that can show me how to display a jpg file from an http link in a popup window or dialog? Nothing fancy, just a simple window to display a 320x240 jpg to the user, with the ability to close the window after review.

I'm using coverflow for some of this now but I first have to copy the jpg files locally then reference the local file. Antonio, I am using the example you shared with me to do this from a file. If coverflow, or any other control, can also display the file directly from the url that would most likely fill my needs.

It seems that this should be easy, not sure why I'm finding it difficult.

Robb,

Please try this code to download an image from a remote URL:

Code: Select all  Expand view  RUN
function URLDownLoad(cUrl, cSaveAs)
local hLib := LOADLIBRARY( "urlmon.dll")
if ! URLDownloadToFile( 0, cUrl, cSaveAs, 0, 0 ) == 0
   return .F.
endif
FreeLibrary( hLib )
return .T.

DLL32 FUNCTION URLDownloadToFile(pCaller AS LONG,szURL AS STRING, szFileName AS STRING, dwReserved AS LONG, lpfnCB AS LONG);
AS LONG PASCAL;
FROM "URLDownloadToFileA";
LIB hlib
regards, saludos

Dear Darrell,

It is a Windows DLL so it is available by default

Very Simple:
Code: Select all  Expand view  RUN
cUrl := "https://www.jesmondfruitbarn.com.au/wp-content/uploads/2016/10/Jesmond-Fruit-Barn-Oranges.jpg"
XIMAGE( cUrl )


Image

First run this two line program and then you will know how to use it with other URLs.
No need to copy locally.
All FWH image functions directly fetch the image from the URL and display.
