WebService Q

Hi there.

I have made a webservice which basically tells the caller if an update is available and sets a global value to the link of the file if an update is available

the caller end, the code basically is:

(globally created the webservice method:

Webservice.something = new Webservice() etc...)

Then to check if there is an update:

something.CheckUpdate(1);

at this point the webservice checks for some stuff, returns true if there is an update else false if there is no update

client (caller) side: if its true then it calls another method to the webservice to get the link to the file (that link to the file has been set by the global variable on the webservice end)

thing is, when I do:

something.GetLinkToFile()

I get returned nothing, just blank string. Any ideas?

How about you return an empty string from CheckUpdate if there is no update, otherwise returns the link to the file if there is.
This would reduce the overhead in serialisation too :)

That is a good suggestion. Also, we'd need to see the code in GetLinkToFile and how you're calling it to see what's wrong. I suggest implementing plenderj's suggestion first.

well yeh thats what I did straight after posting this topic... and it works fine :) its just annoying... you would prefer to do a check to see if there is an update and IF SO then get the link....

but yeh :)
