Compiler problem with API Function URLDownloadToFile

[Marty Francom]

Jose'
   I am converting a very simple FF31/PB9 program that used the WinAPI and would
compile just fine using FF31/PB9/WinAPI   But when I compile using FF35/PB10/JoseAPI
I get the following compile error.  See screen print:

   Any suggestion?   I have attached the project file.

I posted both here and on FireFly Forum.  I am thinking that this may
be an API problem and you may be able to spot the problem quickly.
Anyway any help you can offer is most appreciated.

Use

Code Select Expand


If UrlDownloadToFile(NOTHING, URLPath, LocalPath, 0, NOTHING) = 0 Then


The one in the PB include files is wrongly declared because they don't have support for low-level COM interfaces.

    Thank you for help.
That worked (of coarse) .

But where does the NOTHING variable come from?
I am guessing it must be defined in your APIs.

It's not a variable, but a PB reserved word. It can be used to replace any OBJECT variable parameter.  In this case, the compiler passes a null object (or a pointer to a null object if BYREF) in place of a typical parameter.
