Hi,
I have a "host Window" that contains one (or more) internal windoww.
I need to pass some parameters/info to the internal window, when I open/call the host window.

Any Ideas?

Hi Steven,

Explained here, section "Passing parameters to an internal window": <a class="ExternalLink" rel="nofollow" target="_blank" href="http://doc.windev.com/en-US/?1013259">http://doc.windev.com/en-US/&hellip;</a>

Hi Alexandre,
the problem with the technique described in the above section, is the following:

1) I have code in the host window - say in the initialization section - where I call IW_MyInternalWin.Init(Param1, Param2)

2) I have ALSO code in the INITIALIZATION of the Internal Window.

The code in the initialization of the Internal Window (No 2) fires up BEFORE I call IW_MyInternalWin.Init(Param1, Param2) - in the host !!!!

Is there a way to run code (1) before code (2) ?

I have been using Global Variables to pass the parameters to the IW, but since I had some free time I am trying to see what other options I have ...

Hi Steven,

In my internal windows I just declare global variables in the Global Declarations section of the window and then update them from the main window by a direct reference any time I need them updated.

IW_WindowName.nVariableName = X

Then if I need to refresh the the internal window I use a local procedure in the internal window and call that from my main window

IW_WindowName.LP_LocalProcedureName

This allows me to have the internal windows be responsive to data entered in the main windows.
I use this method in a quite a few areas and it works well.
Hope this helps.

Steve

Hi Steven,

If you use ChangeSourceWindow() you can pass parameters at the same time. (I avoid this path because it only works when using that command.)

I personally do as Steve suggested. In every internal Window I have an Initialize/Refresh command and globals. For simplicity I usually avoid the globals because you always miss something. The Initialize/Refresh command usually receives the arguments that need to be refreshed. (Something like that: Refresh(p is string = gsP, b is bool = gsB), so if you do not specify the params, it uses the globals.)

Best regards,

Thanks Alexandre
I just tested what you and Steve suggested and it works fine
