Hello, I have created help cue cards for a software system that utilizes several different modules. The modules can work together or act as stand-alone applications. Therefore, a client may use 1 or all or any number of modules.

All the cue cards are in one publication. I wrote a script so that when the user clicks a link to a cue card page, the publication searches to see if the module's .exe to which that cue card refers is present on the user's system. If it is, the cue card page is displayed. If the .exe is not present on their system, they get a "sorry" message.

The script works fine. However, I decided I need another related script, and it is that script with which I am having problems.

I use a launch publication search action. The only problem is of course that the search returns the keywords for all cue cards, even those referring to modules that are not present on the user's system.

So, I wrote the following script that I guess I'm going to need to put on every cue card page, so that upon page pre-show, the publication will search for that module's .exe. If the .exe is present, the cue card page will be displayed. If not present, a "sorry" page will be displayed. However, I discovered a problem during testing. If I click on a keyword in the search form and I am taken to the "sorry" page, it opens the "sorry" page, then opens it again - you see the page transition twice.

Here is my script...does anyone know what's going on?
Thanks a bunch,
Mike

if ( FileExists( SYSTEM_PUBLICATION_DIR + "mobcli.exe" ))
{
// File exists - do something
GotoPage("mobile_going_in_service")
}
else
{
// File does not exist - do something else
GotoPage("Sorry")
}

Hi Mike,

Maybe the 'if' and 'else' conditions are happening at once in your script. Try the following...


var check = FileExists( SYSTEM_PUBLICATION_DIR + "mobcli.exe" )
if (check == 1)
{
GotoPage("mobile_going_in_service")
}
else
{
// File does not exist - do something else
GotoPage("Sorry")
}

Hi Steve,
Thanks so much for the quick reply. Unfortunately, that doesn't do the trick. I do appreciate the suggestion.
Mike

Maybe this line works...
if ( FileExists( SYSTEM_PUBLICATION_DIR + "mobcli.exe" )==1)
{action}
else
{action}

Is there any way you can exclude the Sorry page's text from your text search? Go to the Sorry page and uncheck the Use words from text objects on page checkbox. I think it's actually doing it right, because it's displaying the page because it found it in the Publication Search, but then the page is redisplaying because your script is run, hence you get two transitions.

Thanks a lot, bwpatric and Jim. I'll try both of the suggestions and get back to you!

Thanks for your suggestions, everyone; I'm still experiencing the issue. This is baffling, to say the least.

Hi Mike,
your logic is correct -- using a file named CSE.exe, the following script gives the correct answer (at least for me)

var check = FileExists(SYSTEM_PUBLICATION_DIR + "CSE.exe" )
if (check)
{
GotoPage("mobile_going_in_service")
}
else
{
// File does not exist - do something else
GotoPage("Sorry")
}

Sometimes it pays to test logic using Debug.trace so you can see if the problem lies elsewhere.
Caution: Don't test using "if (check==1)" or it will miss a file that is read only, as then check=2.
if(check) will pass any non zero number.

see attached imp.
I've used a file called CSE.exe in my pub to test with, change it accordingly.

cheers

Thanks a bunch, Paul. I'll give it a whirl.

Thanks, everyone, for your suggestions, but I guess this is a lost cause. It's just not working correctly.
