Possible, to send a value from mdi-child to main-window ?
Posted: Sat Apr 26, 2008 11:31 AM

Hello,

I have a little problem :

With one Button in the office-bar (Main-window), i want to know the position inside a folder of a child.
To define a PUBLIC-var at start, doesn't help

Is it possible to use just 1 Button to start a action in relation
of the folder-position ?

Regards

Uwe

If you have any questions about special functions, maybe i can help.

Have you tried oFolder:nOption?

Hello James,

The problem is, i want to start a action in the main-window.
In the main window, i define a var < nPROGPOS = 1 >.
In the Child, the var gets the value from the folder :

ON CHANGE Optionget( nOption, nOldoption)
nPROGPOS := nOption

A Test in the Child => nPROGPOS has the value from the folder-pos.
Inside the child, everything is ok.

But when i press the button in the Main-Window
nPROGPOS is allways 1.

I need the nOption-value in the office-bar.
When it is impossible to do it this way, i have to create a button
in each folder for the needed action.

It seems, nPROGPOS in the Main-window is different to the one
in the Child.
I checked : Public, static, private, by reference
No chance at all.

Regards

Uwe,

Use a static inside a function. You can set it in the child window and retreive it from anywhere.

James

Code: Select all Collapse

function setOption(nNewOption)
   local nReply
   static nOldOption:=1
   nReply:= nOldOption
   if nNewOption != nil
      nOldOption:= nNewOption
   endif
return nReply

Uwe,

>I added the Function to the program and it works fine now.

Glad to hear it. You may want to make the function a static function so it can't be seen elsewhere in your program.
