Re: [MS_AccessPros] Some forms won't open

 

Yes, you will get an error if PartID is Null.  You could try:


Start: CDate(DMin("PartItineraryDate","tblPartItinerary","PartID=" & NZ([tblPart].[PartID], 0)))

Kevin-


Not necessarily.  Are you doing this in the .accde or the .accdb?  If in the .accdb, you should be able to go into Design view to try to figure out what's wrong.  You can't use Design view in a .accde file.

John,
After clicking on some forms, it pops up messeges like:

"Ivalid use of Null"

"The expression is typed incorrectly, or it is too complex to be evaluted, for example, a numeric expression may contain too many complicated elements. Try simplifying expression by assigning pars of the expression to variables."

I think the database is broken, right? What shall I do? Please help!

Best Regards,
Kevin

Kevin-


Please explain what you mean by "some forms won't open."  Note that when you're running in an accde file with the Nav Pane hidden, you must provide command buttons on forms to be able to open forms and reports in your app.  You basically need a Switchboard form that opens on startup that lets you get to all the bits and pieces.

Dear All,

After saving the database as "Make ACCDE", some forms won't open. What should I do? Help!
