Failed to call the function of_getcurrentposition of eon_mobile_geolocationex object
Posted by Nico Wang on 17 September 2013 02:29 PM

Phenomenon: Cannot call the function of_getcurrentposition to get the current position.

Solution 1 (this soluiton is working only for iOS devices): There should be at least one second interval between calling the of_getcurrentposition function and the of_open function, the example is shown as below.

if appeongetclienttype()="MOBILE" then

   eon_mobile_geolocationex  lgnv_aws               

                 lgnv_aws = CREATE eon_mobile_geolocationex                 

                  If lgnv_aws.of_isenabled() = 1 Then

                                lgnv_aws.of_open (0, 1)

                        sleep(1)                               

                                lgnv_aws.of_getcurrentposition (astr_coordinates)

                                lgnv_aws.of_close()                      

                                messagebox('Long',astr_coordinates.dec_longitude)

                                messagebox('Long',astr_coordinates.dec_latitude)

                Else

                                messagebox('', 'GPS Disabled')

                End If               

    destroy lgnv_aws

end if

 

Solution 2 (this solution is working for iOS and Android devices): Alternatively, you can separately execute the of_getcurrentposition function and the of_open function as the example shown below.

//instance variables of w_1 window

   eon_mobile_geolocationex  ignv_aws      

 

//in the constructor event of w_1 window

……

if appeongetclienttype()="MOBILE" then

                 ignv_aws = CREATE eon_mobile_geolocationex      

                  If ignv_aws.of_isenabled() = 1 Then

                               ignv_aws.of_open (0, 1)

                Else

                     destroy ignv_aws          

                      messagebox('', 'GPS Disabled')

                End If               

end if           

……

 

// in clicked event of cb_1 of  w_1 window

……

if isvalid( ignv_aws) then 

          ignv_aws.of_getcurrentposition (astr_coordinates)

          ignv_aws.of_close()                      

          messagebox('Long',astr_coordinates.dec_longitude)

          messagebox('Long',astr_coordinates.dec_latitude)

end if
