Not getting previews with new vpe 4.0 ocx

[BartG]

Hi,

Well, it looks like we had an earlier version of VPE than I thought (I thought we had 3.60, but I am new here, so, sorry about that). The GUID for the OCX of our version is 399548B6-253E-11D2-BE13-000000000000. Maybe that can tell you which version of vpe we really have...

Anyway, I tried to replace the old OCX with the new one, ran the program and got a message regarding the picture method stating that we had the wrong number of parameters. I went into the program, found that we were passing 6 parameters instead of just 5. I modified the statement and passed 5 parameters to PICTURE instead of 6.

The program compiled successfully, but now when I call it, I only get blank pages instead of data for my reports. I'm at a loss since this is my first experience with VPE and Progress. Can you tell me what I'm doing wrong?

[IDEAL Software Support]

Please see the file "Release Notes" installed with VPE v4.0. It contains a section with compatibilty issues. After providing from 3/1999 until 8/2008 a fully compatible API, we had to do some major changes in order to support the new platforms like Mac OS X, Linux and Solaris.

However, VPE can be switched into v3.x compatibility mode by inserting two lines of source code into your existing applications.
