Code to link to Terraview
Terraview Linking Function – ActiveXObject – Shell run
Terraview Delphi Code to link to APEX
•
Uses the Windows ShellExecute API command to force the url to open in a
browser. The URL is forced to open in IE as opposed to the system default
browser, as IE seems to work better with APEX
if (TApex.GetInstance.UseIE) then
res := ShellExecute(0, 'open', 'iexplore', PChar(url), nil, SW_SHOWNORMAL)
else
res := ShellExecute(0, 'open', PChar(url), nil, nil, SW_SHOWNORMAL);
•
The function will open a different APEX report depending on the menu button
if (Sender = ViewAPEXParcelExtent) then
page := TApex.GetInstance.page[20];
url := Format(apex, [Format(page, [XMin, YMin, XMax, YMax])]);
OpenURL;
Terraview INI Code to link to APEX
•
The URL hotlink that is created uses a .INI file setting or a hard-coded
default URL location
