WD11: How to apply color changes on field entry

Startbeitrag von Gianni Spano am 28.04.2008 16:33

Hello to all

My request:

During the input of data in a form, i would like to change automatically the background color
of a textbox during its input (ie yellow) and go back to its previous backcolor (ie white) after it exits from the field.

Now i'm using a "ColorOn()" and a "ColorOff()" routines in the "Entry/Exit" section for each field and sincerily this is a bit annoying because i have to write these commands for every textbox in the form (there are a lot of textboxes).

Does anyone know if it is possibile to intercept when the focus is on a textboxes, then execute a global procedure "ColorOn" and when it leaves the field execute a "ColorOff()", without write these functions in the "entry/exit" secton for every field in the forms?

Thanks in advance



Hello Gianni

Look at events.

Hi Harry

Thanks for your prompt reply.

I was reading the online help for "Event" and there are few examples available, but nothing to solve my problem, because they are focused only for mouse events and it needs a "Window message" to intercept the "entry" or "exit" event (got focus or lost focus) and i don't know which values they need to be passed in the "Event" declaration.

Please, can you post some example here?

Found a solution!!

//Put this code in the Initialization section of the window

nWM_SETFOCUS is int=7
nWM_KILLFOCUS is int=8


It works!!
