Graphs, GRAPH.EXE & WIN.INI

[ChrisMc]

My App is written under FP Windows 2.6a with the fast processor patch applied. On startup and if required it adds to WIN.INI the entry

[MSAPPS]
msapps=c:\windows\msapps

If required it then copies GRAPH.EXE (version 3) to C:\WINDOWS\MSAPPS\MSGRAPH

The App contains an included CONFIG.FPW file with the line _GENGRAPH="PROGRAMS\GENGRAPH.APP" (PROGRAMS is a sub-directory of my App's tree and GENGRAPH.APP exists there) and, for completeness I've added the full file to the end of this note.

I call graphs using Rick Strahl's GGRAPH program. This worked fine and indeed worked on other systems but has now stopped: trying to track down the cause is driving me up the wall. This is the scenario:

If I delete the C:\WINDOWS\MSAPPS directory on my development machine (a P4 with 512Mb RAM running XP Professional), remove the entry from WIN.INI and check by double blipping an OLE Graph general field in a table, I expect & get 'Cannot activate OLE server'. If I then install the App, everything is back & graphs work fine.

HOWEVER, if I install the App on other machines (I've tried XP, ME & 98 - all the same), the entry *is* in WIN.INI and GRAPH.EXE *does* exist in C:\WINDOWS\MSAPPS\MSGRAPH BUT I get the 'Cannot activate OLE server' error and graphs wont work. The machines I tried have sufficient memory - 512Mb on two, 256Mb on the other.

Does anybody have any idea of what else could effect the behaviour? I've totally run out of ideas and I'm begining to seriously doubt my sanity! Thanks in advance to anybody who saves me from the men in white coats.

The answer is of course the good ole' registry

I've updated my FAQ with the required entries, for anybody going down this road.

Hmmm. Makes sense. But it sure didn't come to mind at the time. Glad you got it worked out.
