Google Map Issue

lescoulm — Wed, 29 Jun 2011 12:34:11 GMT

Hi,

I develop a QV application containing a graph with google map.

The map must appear as a dynamic image with the following parameter :

='http://maps.google.com/staticmap?center='
&
num(var_mid_lat, '##############', '.', ',' )
&
','
&
num(var_mid_long, '##############', '.', ',' )
&
'&zoom=$(var_zoom)'
&
'&maptype='&var_maptype
&
'&size='&map_size_x&'x'&map_size_y
&
'&key='&gmap_key & '&.jpg'

My problem is the map does not appear, but if I make File>open URL and I paste the URL, the map appears correctly.

Have you ideas of my problem ?

Thanks.

I frequently encountered the same problem recently. In many cases it was because the transparency of the scatter chart background was set to 100% thus resulting in no background image at all.

I have already tried to modify the transparency but It does not change anything.

I thought It was a problem of firewall, but when I open the URL from QV Desktop, the map appears correctly.

Try to use a tool like fiddler (http://www.fiddler2.com) to look if the request to google maps is done or not when you change selections and what the response was. If you get an image in response then the problem comes from the object configuration, else it is a network security problem.

Thank you for your answer.

Our firewall locks the Internet acces for qv.exe.

I will see this point with our system administrator.
