| I am new to writing Web apps and am having a hard time getting my head around global variables. I would like to be able to use a couple of global variables to hold states, etc. But every time I submit something to the server (a page refresh, new page, etc.), the project initialization code reinitialized the globals. Is there anyway to set a global and keep it throughout a session, or do I just need to pass those values as parameters to all of my different pages? Thanks |

Hi Peter,
it depends of the type of pages you are using: classic, awp or php
Best regards |

| Currently the project site is configured as Dynamic AWP. I have 5 globals defined in project server initialization. That initialization code seems to be recalled each time a page is refreshed, |

Hi
If you use dunamic webdev then your globals are useble the way you discribe. If you use AWP you have to pass the global to the page as a param.
In the calling of the page
pagedisplay( thepageyou call, paramglobal)
In the page that is called add a procedure
PROCEDURE mypage( var is string )
Then use var to get the value of you global
regards

Hi,
Thank you Allard. I think I'll pass them as suggested. Hopefully I can use a composite variable to pass them all easily. I changed the project to Dynamic Webdev, put a break in the server init code, and it still calls the reinitialization of the globals. Don't know why - will try above and scratch my head another day on this one. |

Hi Peter,
You can declare an AWP context to store your global variables in AWP mode (server side if you want).
Check ConfigureAWPContext() and DeclareAWPContext() in the help for that.
In the project init code you get the previous values again stored by these same commands.
Best regards,
Peter Holemans |

Hi Peter,
That sounds like the ticket. I'll give it a try - Thanks. |
