Calling one event procedure from another - HOW-TO? 1

[IlyaRabyy]

Colleagues,
In other IV-level languages (at least B4 .NET), I could do something like this (quasi-code, of course)

PROC cboNumOfItems.SelectedIndexChanged()
IF cboNumOfItems.Selected Index > 0
   chkAllInOne.Enabled = True
ELSE
   chkAllInOne.Enabled = False
ENDIF
ENDPROC

PROC cboNumOfItems.KeyPress(KeyCode)
IF KeyCode = 13
   cboNumOfItems.SelectedIndexChanged() ' Calling another event procedure
ENDIF
ENDPROC

As it happens, such a need arose in my project (VS 2019, VB .NET). I tried to figure out how to do this call - and failed.
And this article in Help,

https://learn.microsoft.com/en-us/d...ures/procedures/how-to-call-an-event-handler,

doesn't help me.

Could anyone here "translate" this above code into this modern VB .NET, please?
TIA!


Regards,

Ilya

Thank you, Andy, but unfortunately ComboBox has no PerformElectedInedxChanged() method, only the one on the screenshot, PerformLayout.

And even that latter can't be found in the MS documentation:

https://learn.microsoft.com/en-us/d...ws.controls.combobox?view=windowsdesktop-6.0:

Any other suggestions, colleagues, would be greatly appreciated!

Regards,

Ilya

Another way would be:

PROC cboNumOfItems.SelectedIndexChanged()
    [blue]Call JustDoIt()[/blue]
ENDPROC

PROC cboNumOfItems.KeyPress(KeyCode)
IF KeyCode = 13
   [blue]Call JustDoIt()[/blue] [green]' Calling another event procedure[/green]
ENDIF
ENDPROC 

PROC [blue]JustDoIt()[/blue]
IF cboNumOfItems.Selected Index > 0
   chkAllInOne.Enabled = True
ELSE
   chkAllInOne.Enabled = False
ENDIF
END PROC

Got it!
Thank you!

(I wonder why I didn't think it up myself... gettin' older, I guess! :-( )
