check on get

[Otto]

Dear João,
it's difficult in a foreign language.
I just wanted to say that one shouldn't see and hear everything during full moon times.
It's not a criticism of you.
With kind regards,
Otto

Mr. Otto,

Function test()
local aGet:=array(2)
local oDlg
local cGet1:=space(60)
local cGet2:=space(60)
local lSave:=.f.
local bCheck
local oBtn1,oBtn2

ACTIVATE DIALOG oDlg
return nil
 

What was hard?

Than I asked another question, not how save with lsave....

Do you think about ?


I only asked how check if the get are changed when the user press Exit or Ok button, you Know how make it ?

Joao always responds by inserting source code that has nothing to do with the request of the topic, after all he doesn't do it only and exclusively to me but to several people, only that sometimes if the person who made the request really needs the help, We are very upset when we read your answers,
Otto, it's like if I came to your hotel and asked for a double room and you pretend nothing happened and just give me a cot and in the garage, do you think it's the same thing?

//aGet
lAsk:= Aeval( aGet, { | o | o:lChanged } )

or
Aeval( aGet, { | o | if(o:lChanged,lAsk := .t.,.f.) } )

give me error

Give me an error , how I can resolve to check all gets ?

[Silvio.Falconi]

I tried to found the result of oGet:lchanged and give me no exist

Code:
Error occurred at: 27-11-2023, 11:06:45

This error means that oGet is NIL

Nages,

I tried with

Aeval( aGet, { | o | if(o != nil .and. o:IsKindOf( "TGET" ) .and. o:lChanged,lAsk := .t.,.f.) } ) //this give me allways .t.

Si no cambio los valores de los gets, a mi me devuelve falso esa funcion

[Silvio.Falconi]

el valor .t siempre me resulta extraño.

[nageswaragunupudi]

el valor .t siempre me resulta extraño.

Please let us know the FWH version

Nages,

> ACTION ( If( lSave, MsgInfo( "Save" ), ), oDlg:End() )

to not use the lsave variable and not to change all the dialogs that I have already done for many years

it is possible to use ( oDlg:end( IDOK ) ) and ( oDlg:end( IDCANCEL ) ) ?

and use
IF oDlg:nresult == IDOK
orec:save()
ENDIF

if I have to change all the insertion dialogs to check the get controls with the lsave variable I prefer not to do it, I waste years changing everything

[nageswaragunupudi]

Simple

Code: Select all  Expand view  RUN

@ r,c BUTTON .......... ;
ACTION If( DlgModified( oDlg ), ID_OK, ID_CANCEL )

Dear Mr. Rao,
I have recreated the example with webview. Perhaps we could enhance it with the function

var s = SendToFWH(evt.target.id, evt.type, someData)
.then(s => {
alert(s.result);
})


We could then build a UI with the webview as a template.

Just an idea.

Kind regards,
Otto

Sorry Otto What does this have to do with the request I made?
It's not related to the topic.
I didn't ask how to do it on the web
