Instead of DirectoryExists() you can use FileExists(), it also works for directories.

Dear CJ -

   This was originally meant to replace the entry in the PFC (pfeapsrv.n_cst_filesrvwin32.of_DirectoryExists).

   If you are not using the PFC, or do not wish to overwrite the PFC entry, you can create a new FileServices NVO and add it as a function there.

1) For GOTO's you can usually recode the event/function to drop the GOTOs.

2_ The DirectoryExists() function needs to be replaced. In stead of using the built-in PowerBuilder version of this function, create your own. This is the answer that was posted a while back from Paul Mele.

If you are not using PFC, this is what we use...

Declare local external
-----------------------------
Function ulong    GetCurrentDirectoryA (ulong buf, ref string wdir) Library "kernel32.dll"
Function boolean SetCurrentDirectoryA (ref string cdir) Library "kernel32.dll"

Function call
-----------------
// **********************************************************
// DirectoryExist
//
// Parms: as_dirname - path to be checked
//
// Returns: True on success, False on failure
// **********************************************************
Boolean lb_rtn=False
String ls_tmp

If IsNull(as_dirname)=False And as_dirname<>"" Then
 If Right(as_dirname,1)="\" Then as_dirname = Left(as_dirname,Len(as_dirname)-1)

 // Attempt to set dir as current
 // Return as failure indicates dir does not exist
 // If it is set, then reset back to current
 ls_tmp = This.GetCurrentDirectory()
 If This.SetCurrentDirectory(as_dirname)=True Then
  lb_rtn=True
  This.SetCurrentDirectory(ls_tmp)
 End If
End If
Return lb_rtn

Good Luck,

I don't know what is going on with your items 1 and 3... you may need to open a support ticket for these two issues.

What John and Mike said is exactly right.  So regarding your items 2, 4, and 5, you will need to remediate these unsupported features.  Just to clarify, you can use the PFC framework with PowerServer, which many Appeon customers do, but you will need to put some time to clean it up.

If you don't want to deal with remediating these unsupported features, then you need to wait for PowerServer 2021.  We are going to basically close the gap on unsupported features.  I would recommend to subscribe to our mailing list so you get notified.

Hi, CJ -

As for your question #4, I suspect this is because no one has volunteered to take on the effort and responsibility to review and update the many tens of thousands of lines of code contained in the PFC libraries. The PFC is well into its third decade of existence - it was designed solely for a client/server paradigm, not the web/cloud/mobile environments many projects are being targeted for today. The PFC is open source, so there is no consortium or group that promotes or oversees the development of enhancements. Although Bruce Armstrong graciously administers the PFC repository (Thank you, Bruce!), it is not his responsibility to provide enhancements. Instead, it's everyone's responsibility, and no one's.

I don't know about your situation, but I suspect it is similar to most of us: Our employers and our managers require us to work on their projects and we generally don't get paid to do volunteer work or "pet" projects that we personally would like to do. Even if a company were to take on a review and partial rewrite of the PFC to make it PowerServer compatible, they probably would view that enhancement as a competitive advantage and be against making it available to anyone and everyone. That's just the way it is.

If you're attempting to take a legacy PB application that was built upon the PFC and migrate it into the PowerServer environment and are experiencing significant difficulties, maybe what you're trying to do is not feasible or reasonable for your situation.

Regards / John

well, #2 and #5 are really the same answer.  PowerServer supports most of powerscript, but not all of it.  you need to review your code and make changes as needed.
