OP is not saying users share a FE, they each have their own copy - but all those copies are the same folder and there is nothing to prevent them opening the ‘wrong’ copy
you can simplify your code
for example
Public Sub setColours(sStr As String, frm As Form)
Dim bc as long
Dim str As String
Dim ctl As Control
bc=rgb(240 ,240,240) ' default colour if "Notes" is null
Select Case sStr
Case "boxes"...
That is also a no no. Wi-Fi can drop connections then reconnect but the FE will lose track of the BE. Worse when working from home since you are dealing with a router as well. It is probably the reason for your issue.
If it has to be WiFi and users work from home I suggest review using terminal...
How are the users opening their front end? By selecting the file? a shortcut? something else?
When you say you have put the FE back on the server, how do you ensure they open their copy and not someone else's? (generally a bad idea to have them on the server anyway - impacts performance among...
My experience is with northwind - if I download and open with 32bit access, all well and good. If I then try to I open the same file (having previously opened with 32bit) with 64 bit I get errors. Same if I open the other way round
Way to go👍
I created an app for cataloging photos- it populated the file properties with keywords and used a tree view type form to create and catalog the keywords and view the files in a web browser control
But don’t think it meets your requirements as it is not generic enough
Perhaps the OP can provide some example data and the outcome required from that data and clarify what ‘not working’ means - wrong result? Something else?
